Not all of Ambassador's existing API (or even most of\n\/\/ it!?) follow these guidelines, but new additions to the API should.\n\/\/ If\/when we advance to getambassador.io\/v3 and we can break\n\/\/ compatibility, these are things that we should apply everywhere.\n\/\/\n\/\/ - Prefer `camelCase` to `snake_case`\n\/\/   * Exception: Except for consistency with existing fields in the\n\/\/     same resource, or symmetry with identical fields in another\n\/\/     resource.\n\/\/   * Justification: Kubernetes style is to use camelCase. But\n\/\/     historically Ambassador used snake_case for everything.\n\/\/\n\/\/ - Prefer for object references to not support namespacing\n\/\/   * Exception: If there's a real use-case for it.\n\/\/   * Justification: Most native Kubernetes resources don't support\n\/\/     referencing things in a different namespace.  We should be\n\/\/     opinionated and not support it either, unless there's a good\n\/\/     reason to in a specific case.\n\/\/\n\/\/ - Prefer to use `corev1.LocalObjectReference` or\n\/\/   `corev1.SecretReference` references instead of\n\/\/   `{name}.{namespace}` strings.\n\/\/   * Justification: The `{name}.{namespace}` thing evolved \"an\n\/\/     opaque DNS name\" in the `service` field of Mappings, and that\n\/\/     was generalized to other things.  Outside of the context of\n\/\/     \"this is usable as a DNS name to make a request to\", it's just\n\/\/     confusing and introduces needless ambiguity.  Nothing other\n\/\/     than Ambassador uses that notation.\n\/\/   * Notes: For things that don't support cross-namespace references\n\/\/     (see above), use LocalObjectReference; if you really must\n\/\/     support cross-namespace references, then use SecretReference.\n\/\/\n\/\/ - Prefer to use `metav1.Duration` fields instead of \"_s\" or \"_ms\"\n\/\/   numeric fields.\n\/\/\n\/\/ - Don't have Ambassador populate anything in the `.spec` or\n\/\/   `.metadata` of something a user might edit, only let Ambassador\n\/\/   set things in the `.status`.\n\/\/   * Exception: If Ambassador 100% owns the resource and a user will\n\/\/     never edit it.\n\/\/   * Notes: I didn't write \"Prefer\" on this one.  Don't violate it.\n\/\/     Just don't do it.  Ever.  Designing the Host resource in\n\/\/     violation of this was a HUGE mistake and one that I regret very\n\/\/     much.  Learn from my mistakes.\n\/\/   * Justification: Having Ambassador-set things in a subresource\n\/\/     from user-set things:\n\/\/     1. avoids races between the user updating the spec and us\n\/\/        updating the status\n\/\/     2. allows watt\/whatever to only pay attention to\n\/\/        .metadata.generation instead of .metadata.resourceVersion;\n\/\/        avoiding pointless reconfigures.\n\/\/     3. allows the RBAC to be simpler\n\/\/     4. avoids the whole class of bugs where we need to make sure\n\/\/        that everything round-trips correctly\n\/\/     5. provides clarity on which things a user is expected to know\n\/\/        how to fill in\n\npackage v2\n\nimport (\n\t\"encoding\/json\"\n)\n\n\/\/ The old `k8s.io\/kube-openapi\/cmd\/openapi-gen` command had ways to\n\/\/ specify custom schemas for your types (1: define a \"OpenAPIDefinition\"\n\/\/ method, or 2: define a \"OpenAPIV3Definition\" method, or 3: define\n\/\/ \"OpenAPISchemaType\" and \"OpenAPISchemaFormat\" methods).  But the new\n\/\/ `sigs.k8s.io\/controller-tools\/controller-gen` command doesn't; it just\n\/\/ has a small number of \"+kubebuilder:\" magic comments (\"markers\") that we\n\/\/ can use to influence the schema it generates.\n\/\/\n\/\/ So, for example, we'd like to define the AmbassadorID schema as:\n\/\/\n\/\/    oneOf:\n\/\/    - type: \"string\"\n\/\/    - type: \"array\"\n\/\/    items:             # only matters if type=array\n\/\/      type: \"string\"\n\/\/\n\/\/ but if we're going to use just vanilla controller-gen, we're forced to\n\/\/ be dumb and say `+kubebuilder:validation:Type=\"\"`, to define its schema\n\/\/ as\n\/\/\n\/\/    # no `type:` setting because of the +kubebuilder marker\n\/\/    items:\n\/\/      type: \"string\"  # because of the raw type\n\/\/\n\/\/ and then kubectl and\/or the apiserver won't be able to validate\n\/\/ AmbassadorID, because it won't be validated until we actually go to\n\/\/ UnmarshalJSON it when it makes it to Ambassador.  That's pretty much\n\/\/ what Kubernetes itself[1] does for the JSON Schema types that are unions\n\/\/ like that.\n\/\/\n\/\/  > Aside: Some recent work in controller-gen[2] *strongly* suggests that\n\/\/  > setting `+kubebuilder:validation:Type=Any` instead of `:Type=\"\"` is\n\/\/  > the proper thing to do.  But, um, it doesn't work... kubectl would\n\/\/  > say things like:\n\/\/  >\n\/\/  >    Invalid value: \"array\": spec.ambassador_id in body must be of type Any: \"array\"\n\/\/\n\/\/ But honestly that's dumb, and we can do better than that.\n\/\/\n\/\/ So, option one choice would be to send the controller-tools folks a PR\n\/\/ to support the openapi-gen methods to allow that customization.  That's\n\/\/ probably the Right Thing, but that seemed like more work than option\n\/\/ two.  FIXME(lukeshu): Send the controller-tools folks a PR.\n\/\/\n\/\/ Option two: Say something nonsensical like\n\/\/ `+kubebuilder:validation:Type=\"d6e-union\"`, and teach the `fix-crds`\n\/\/ script to notice that and delete that nonsensical `type`, replacing it\n\/\/ with the appropriate `oneOf: [type: A, type: B]` (note that the version\n\/\/ of JSONSchema that OpenAPI\/Kubernetes uses doesn't support type being an\n\/\/ array).  And so that's what I did.\n\/\/\n\/\/ FIXME(lukeshu): But all of that is still terrible.  Because the very\n\/\/ structure of our data inherently means that we must have a\n\/\/ non-structural[3] schema.  With \"apiextensions.k8s.io\/v1beta1\" CRDs,\n\/\/ non-structural schemas disable several features; and in v1 CRDs,\n\/\/ non-structural schemas are entirely forbidden.  I mean it doesn't\n\/\/ _really_ matter right now, because we give out v1beta1 CRDs anyway\n\/\/ because v1 only became available in Kubernetes 1.16 and we still support\n\/\/ down to Kubernetes 1.11; but I don't think that we want to lock\n\/\/ ourselves out from v1 forever.  So I guess that means when it comes time\n\/\/ for `getambassador.io\/v3` (`ambassadorlabs.com\/v1`?), we need to\n\/\/ strictly avoid union types, in order to avoid violating rule 3 of\n\/\/ structural schemas.  Or hope that the Kubernetes folks decide to relax\n\/\/ some of the structural-schema rules.\n\/\/\n\/\/ [1]: https:\/\/github.com\/kubernetes\/apiextensions-apiserver\/blob\/kubernetes-1.18.4\/pkg\/apis\/apiextensions\/v1beta1\/types_jsonschema.go#L195-L206\n\/\/ [2]: https:\/\/github.com\/kubernetes-sigs\/controller-tools\/pull\/427\n\/\/ [3]: https:\/\/kubernetes.io\/docs\/tasks\/extend-kubernetes\/custom-resources\/custom-resource-definitions\/#specifying-a-structural-schema\n\ntype CircuitBreaker struct {\n\t\/\/ +kubebuilder:validation:Enum={\"default\", \"high\"}\n\tPriority           string `json:\"priority,omitempty\"`\n\tMaxConnections     *int   `json:\"max_connections,omitempty\"`\n\tMaxPendingRequests *int   `json:\"max_pending_requests,omitempty\"`\n\tMaxRequests        *int   `json:\"max_requests,omitempty\"`\n\tMaxRetries         *int   `json:\"max_retries,omitempty\"`\n}\n\n\/\/ ErrorResponseTextFormatSource specifies a source for an error response body\ntype ErrorResponseTextFormatSource struct {\n\t\/\/ The name of a file on the Ambassador pod that contains a format text string.\n\tFilename string `json:\"filename\"`\n}\n\n\/\/ ErorrResponseOverrideBody specifies the body of an error response\ntype ErrorResponseOverrideBody struct {\n\t\/\/ A format string representing a text response body.\n\t\/\/ Content-Type can be set using the `content_type` field below.\n\tErrorResponseTextFormat string `json:\"text_format,omitempty\"`\n\n\t\/\/ A JSON response with content-type: application\/json.

The general algorithm is this:\n\t\/\/ - HTTP trail samples will be collected separately and not\n\t\/\/   included in the default sample buffer (which is directly sent\n\t\/\/   to the cloud service every MetricPushInterval).\n\t\/\/ - On every AggregationCalcInterval, all collected HTTP Trails will be\n\t\/\/   split into AggregationPeriod-sized time buckets (time slots) and\n\t\/\/   then into sub-buckets according to their tags (each sub-bucket\n\t\/\/   will contain only HTTP trails with the same sample tags -\n\t\/\/   proto, staus, URL, method, etc.).\n\t\/\/ - If at that time the specified AggregationWaitPeriod has not passed\n\t\/\/   for a particular time bucket, it will be left undisturbed until the next\n\t\/\/   AggregationCalcInterval tick comes along.\n\t\/\/ - If AggregationWaitPeriod has passed for a time bucket, all of its\n\t\/\/   sub-buckets will be traversed. Any sub-buckets that have less than\n\t\/\/   AggregationMinSamples HTTP trails in them will not be aggregated.\n\t\/\/   Instead the HTTP trails in them will just be individually added\n\t\/\/   to the default sample buffer, like they would be if there was no\n\t\/\/   aggregation.\n\t\/\/ - Sub-buckets with at least AggregationMinSamples HTTP trails on the\n\t\/\/   other hand will be aggregated according to the algorithm below:\n\t\/\/     - If AggregationSkipOutlierDetection is enabled, all of the collected\n\t\/\/       HTTP trails in that sub-bucket will be directly aggregated into a single\n\t\/\/       compoind metric sample, without any attempt at outlier detection.\n\t\/\/       IMPORTANT: This is intended only for testing purposes only or, in\n\t\/\/       extreme cases, when the resulting metrics' precision isn't very important,\n\t\/\/       since it could lead to a huge loss of granularity and the masking\n\t\/\/       of any outlier samples in the data.\n\t\/\/     - By default (since AggregationSkipOutlierDetection is not enabled),\n\t\/\/       the collected HTTP trails will be checked for outliers, so we don't loose\n\t\/\/       granularity by accidentally aggregating them. That happens by finding\n\t\/\/       the \"quartiles\" (by default the 75th and 25th percentiles) in the\n\t\/\/       sub-bucket datapoints and using the inter-quartile range (IQR) to find\n\t\/\/       any outliers (https:\/\/en.wikipedia.org\/wiki\/Interquartile_range#Outliers,\n\t\/\/       though the specific parameters and coefficients can be customized\n\t\/\/       by the AggregationOutlier{Radius,CoefLower,CoefUpper} options)\n\t\/\/     - Depending on the number of samples in the sub-bucket, two different\n\t\/\/       algorithms could be used to calculate the quartiles. If there are\n\t\/\/       fewer samples (between AggregationMinSamples and AggregationOutlierAlgoThreshold),\n\t\/\/       then a more precise but also more computationally-heavy sorting-based algorithm\n\t\/\/       will be used. For sub-buckets with more samples, a lighter quickselect-based\n\t\/\/       algorithm will be used, potentially with a very minor loss of precision.\n\t\/\/     - Regardless of the used algorithm, once the quartiles for that sub-bucket\n\t\/\/       are found and the IQR is calculated, every HTTP trail in the sub-bucket will\n\t\/\/       be checked if it seems like an outlier. HTTP trails are evaluated by two different\n\t\/\/       criteria whether they seem like outliers - by their total connection time (i.e.\n\t\/\/       http_req_connecting + http_req_tls_handshaking) and by their total request time\n\t\/\/       (i.e. http_req_sending + http_req_waiting + http_req_receiving).

The general algorithm is this:\n\t\/\/ - HTTP trail samples will be collected separately and not\n\t\/\/   included in the default sample buffer (which is directly sent\n\t\/\/   to the cloud service every MetricPushInterval).\n\t\/\/ - On every AggregationCalcInterval, all collected HTTP Trails will be\n\t\/\/   split into AggregationPeriod-sized time buckets (time slots) and\n\t\/\/   then into sub-buckets according to their tags (each sub-bucket\n\t\/\/   will contain only HTTP trails with the same sample tags -\n\t\/\/   proto, staus, URL, method, etc.).\n\t\/\/ - If at that time the specified AggregationWaitPeriod has not passed\n\t\/\/   for a particular time bucket, it will be left undisturbed until the next\n\t\/\/   AggregationCalcInterval tick comes along.\n\t\/\/ - If AggregationWaitPeriod has passed for a time bucket, all of its\n\t\/\/   sub-buckets will be traversed. Any sub-buckets that have less than\n\t\/\/   AggregationMinSamples HTTP trails in them will not be aggregated.\n\t\/\/   Instead the HTTP trails in them will just be individually added\n\t\/\/   to the default sample buffer, like they would be if there was no\n\t\/\/   aggregation.\n\t\/\/ - Sub-buckets with at least AggregationMinSamples HTTP trails on the\n\t\/\/   other hand will be aggregated according to the algorithm below:\n\t\/\/     - If AggregationSkipOutlierDetection is enabled, all of the collected\n\t\/\/       HTTP trails in that sub-bucket will be directly aggregated into a single\n\t\/\/       compoind metric sample, without any attempt at outlier detection.\n\t\/\/       IMPORTANT: This is intended only for testing purposes only or, in\n\t\/\/       extreme cases, when the resulting metrics' precision isn't very important,\n\t\/\/       since it could lead to a huge loss of granularity and the masking\n\t\/\/       of any outlier samples in the data.\n\t\/\/     - By default (since AggregationSkipOutlierDetection is not enabled),\n\t\/\/       the collected HTTP trails will be checked for outliers, so we don't loose\n\t\/\/       granularity by accidentally aggregating them. That happens by finding\n\t\/\/       the \"quartiles\" (by default the 75th and 25th percentiles) in the\n\t\/\/       sub-bucket datapoints and using the inter-quartile range (IQR) to find\n\t\/\/       any outliers (https:\/\/en.wikipedia.org\/wiki\/Interquartile_range#Outliers,\n\t\/\/       though the specific parameters and coefficients can be customized\n\t\/\/       by the AggregationOutlier{Radius,CoefLower,CoefUpper} options)\n\t\/\/     - Depending on the number of samples in the sub-bucket, two different\n\t\/\/       algorithms could be used to calculate the quartiles. If there are\n\t\/\/       fewer samples (between AggregationMinSamples and AggregationOutlierAlgoThreshold),\n\t\/\/       then a more precise but also more computationally-heavy sorting-based algorithm\n\t\/\/       will be used. For sub-buckets with more samples, a lighter quickselect-based\n\t\/\/       algorithm will be used, potentially with a very minor loss of precision.\n\t\/\/     - Regardless of the used algorithm, once the quartiles for that sub-bucket\n\t\/\/       are found and the IQR is calculated, every HTTP trail in the sub-bucket will\n\t\/\/       be checked if it seems like an outlier. HTTP trails are evaluated by two different\n\t\/\/       criteria whether they seem like outliers - by their total connection time (i.e.\n\t\/\/       http_req_connecting + http_req_tls_handshaking) and by their total request time\n\t\/\/       (i.e. http_req_sending + http_req_waiting + http_req_receiving).

Hence, the code does\n\/\/ knowingly not account for this value wrapping around.

The sequencer sits in front of them all, controlling the\n\/\/ entry into \"new territory\". Once the sequencer increments further into the number sequence, other pointers\n\/\/ in the queue may increment up to the point the sequencer is at.\n\/\/\n\/\/ The sequencer does this, while maintaining a key invariant: The infinite sequence of numbers is mapped onto\n\/\/ a circular buffer, which is distinctly not infinite. Hence, the sequencer keeps track of all the secondary\n\/\/ sequence pointers, and ensures the delta from the lowest pointer to the sequencer pointer never is greater\n\/\/ than the size of the buffer.\n\/\/\n\/\/ At the end of the day, the sequencer is really just:\n\/\/\n\/\/   func next(n) {\n\/\/       if cursor + n < min(otherPointersInTheQueue) {\n\/\/           cursor += n\n\/\/       }\n\/\/       return cursor\n\/\/   }\n\/\/\n\/\/ The neat thing is that it does the above using some really clever techniques that make the sequencer\n\/\/ safe for concurrent use, and extremely low overhead to boot.\ntype sequencer struct {\n\tbufferSize   int64\n\twaitStrategy WaitStrategy\n\n\t\/\/ This is the golden cursor - it points to the highest number the sequencer (and hence any other pointer)\n\t\/\/ has reached in our supposedly infinite sequence of numbers\n\tcursor *sequence\n\n\t\/\/ This is the other pointer (soon to be multiple, but one for now) in the queue - the sequencer makes sure\n\t\/\/ it doesn't get further ahead of this than bufferSize, otherwise we'd wrap around the buffer and overwrite\n\t\/\/ slots before they had been processed.\n\tgatingSequence      *sequence\n\tgatingSequenceCache *sequence\n\n\t\/\/ Tracks published slots.

All running transactions must complete before the\nmethod will be called on the underlying lmdb.Env.\n\nIf an open transaction depends on a change in map size then the database will\ndeadlock and block all future transactions in the environment.  Put simply, all\ntransactions must terminate independently of other transactions.\n\nIn the simplest example, a function in view transaction that attempts an update\nwill deadlock database if the map is full and an increase of the map size is\nattempted so the transaction can be retried.  Instead the update should be\nprepared inside the view and then executed following the termination of the\nview.\n\nThe developers of LMDB officially recommend against applications changing the\nmemory map size for an open database.

Usage of\nthe MapFullHandler puts important caveats on how one can safely work with\ntransactions.  See the function documentation for more detailed information.\n\nThe caveats on transactions are lessened if lmdb.MapFull is the only error\nbeing handled (when multi-processing is not a concern).

It is\nunclear what benefits this provides.\n\nUsage of lmdb.NoLock requires that update transactions acquire an exclusive\nlock on the environment.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/\/ Garbage collector: write barriers.\n\/\/\n\/\/ For the concurrent garbage collector, the Go compiler implements\n\/\/ updates to pointer-valued fields that may be in heap objects by\n\/\/ emitting calls to write barriers. This file contains the actual write barrier\n\/\/ implementation, markwb, and the various wrappers called by the\n\/\/ compiler to implement pointer assignment, slice assignment,\n\/\/ typed memmove, and so on.\n\npackage runtime\n\nimport \"unsafe\"\n\n\/\/ markwb is the mark-phase write barrier, the only barrier we have.\n\/\/ The rest of this file exists only to make calls to this function.\n\/\/\n\/\/ This is the Dijkstra barrier coarsened to always shade the ptr (dst) object.\n\/\/ The original Dijkstra barrier only shaded ptrs being placed in black slots.\n\/\/\n\/\/ Shade indicates that it has seen a white pointer by adding the referent\n\/\/ to wbuf as well as marking it.\n\/\/\n\/\/ slot is the destination (dst) in go code\n\/\/ ptr is the value that goes into the slot (src) in the go code\n\/\/\n\/\/\n\/\/ Dealing with memory ordering:\n\/\/\n\/\/ Dijkstra pointed out that maintaining the no black to white\n\/\/ pointers means that white to white pointers not need\n\/\/ to be noted by the write barrier. Furthermore if either\n\/\/ white object dies before it is reached by the\n\/\/ GC then the object can be collected during this GC cycle\n\/\/ instead of waiting for the next cycle. Unfortunately the cost of\n\/\/ ensure that the object holding the slot doesn't concurrently\n\/\/ change to black without the mutator noticing seems prohibitive.\n\/\/\n\/\/ Consider the following example where the mutator writes into\n\/\/ a slot and then loads the slot's mark bit while the GC thread\n\/\/ writes to the slot's mark bit and then as part of scanning reads\n\/\/ the slot.\n\/\/\n\/\/ Initially both [slot] and [slotmark] are 0 (nil)\n\/\/ Mutator thread          GC thread\n\/\/ st [slot], ptr          st [slotmark], 1\n\/\/\n\/\/ ld r1, [slotmark]       ld r2, [slot]\n\/\/\n\/\/ Without an expensive memory barrier between the st and the ld, the final\n\/\/ result on most HW (including 386\/amd64) can be r1==r2==0. This is a classic\n\/\/ example of what can happen when loads are allowed to be reordered with older\n\/\/ stores (avoiding such reorderings lies at the heart of the classic\n\/\/ Peterson\/Dekker algorithms for mutual exclusion). Rather than require memory\n\/\/ barriers, which will slow down both the mutator and the GC, we always grey\n\/\/ the ptr object regardless of the slot's color.\n\/\/\n\/\/ Another place where we intentionally omit memory barriers is when\n\/\/ accessing mheap_.arena_used to check if a pointer points into the\n\/\/ heap. On relaxed memory machines, it's possible for a mutator to\n\/\/ extend the size of the heap by updating arena_used, allocate an\n\/\/ object from this new region, and publish a pointer to that object,\n\/\/ but for tracing running on another processor to observe the pointer\n\/\/ but use the old value of arena_used. In this case, tracing will not\n\/\/ mark the object, even though it's reachable. However, the mutator\n\/\/ is guaranteed to execute a write barrier when it publishes the\n\/\/ pointer, so it will take care of marking the object. A general\n\/\/ consequence of this is that the garbage collector may cache the\n\/\/ value of mheap_.arena_used. (See issue #9984.)\n\/\/\n\/\/\n\/\/ Stack writes:\n\/\/\n\/\/ The compiler omits write barriers for writes to the current frame,\n\/\/ but if a stack pointer has been passed down the call stack, the\n\/\/ compiler will generate a write barrier for writes through that\n\/\/ pointer (because it doesn't know it's not a heap pointer).\n\/\/\n\/\/ One might be tempted to ignore the write barrier if slot points\n\/\/ into to the stack. Don't do it! Mark termination only re-scans\n\/\/ frames that have potentially been active since the concurrent scan,\n\/\/ so it depends on write barriers to track changes to pointers in\n\/\/ stack frames that have not been active. go:nowritebarrier\nfunc gcmarkwb_m(slot *uintptr, ptr uintptr) {\n\tif writeBarrierEnabled {\n\t\tif ptr != 0 && inheap(ptr) {\n\t\t\tshade(ptr)\n\t\t}\n\t}\n}\n\n\/\/ Write barrier calls must not happen during critical GC and scheduler\n\/\/ related operations. In particular there are times when the GC assumes\n\/\/ that the world is stopped but scheduler related code is still being\n\/\/ executed, dealing with syscalls, dealing with putting gs on runnable\n\/\/ queues and so forth.

This file contains the actual write barrier\n\/\/ implementation, markwb, and the various wrappers called by the\n\/\/ compiler to implement pointer assignment, slice assignment,\n\/\/ typed memmove, and so on.\n\npackage runtime\n\nimport \"unsafe\"\n\n\/\/ markwb is the mark-phase write barrier, the only barrier we have.\n\/\/ The rest of this file exists only to make calls to this function.\n\/\/\n\/\/ This is the Dijkstra barrier coarsened to always shade the ptr (dst) object.\n\/\/ The original Dijkstra barrier only shaded ptrs being placed in black slots.\n\/\/\n\/\/ Shade indicates that it has seen a white pointer by adding the referent\n\/\/ to wbuf as well as marking it.\n\/\/\n\/\/ slot is the destination (dst) in go code\n\/\/ ptr is the value that goes into the slot (src) in the go code\n\/\/\n\/\/\n\/\/ Dealing with memory ordering:\n\/\/\n\/\/ Dijkstra pointed out that maintaining the no black to white\n\/\/ pointers means that white to white pointers not need\n\/\/ to be noted by the write barrier. Furthermore if either\n\/\/ white object dies before it is reached by the\n\/\/ GC then the object can be collected during this GC cycle\n\/\/ instead of waiting for the next cycle. Unfortunately the cost of\n\/\/ ensure that the object holding the slot doesn't concurrently\n\/\/ change to black without the mutator noticing seems prohibitive.\n\/\/\n\/\/ Consider the following example where the mutator writes into\n\/\/ a slot and then loads the slot's mark bit while the GC thread\n\/\/ writes to the slot's mark bit and then as part of scanning reads\n\/\/ the slot.\n\/\/\n\/\/ Initially both [slot] and [slotmark] are 0 (nil)\n\/\/ Mutator thread          GC thread\n\/\/ st [slot], ptr          st [slotmark], 1\n\/\/\n\/\/ ld r1, [slotmark]       ld r2, [slot]\n\/\/\n\/\/ Without an expensive memory barrier between the st and the ld, the final\n\/\/ result on most HW (including 386\/amd64) can be r1==r2==0. This is a classic\n\/\/ example of what can happen when loads are allowed to be reordered with older\n\/\/ stores (avoiding such reorderings lies at the heart of the classic\n\/\/ Peterson\/Dekker algorithms for mutual exclusion). Rather than require memory\n\/\/ barriers, which will slow down both the mutator and the GC, we always grey\n\/\/ the ptr object regardless of the slot's color.\n\/\/\n\/\/ Another place where we intentionally omit memory barriers is when\n\/\/ accessing mheap_.arena_used to check if a pointer points into the\n\/\/ heap. On relaxed memory machines, it's possible for a mutator to\n\/\/ extend the size of the heap by updating arena_used, allocate an\n\/\/ object from this new region, and publish a pointer to that object,\n\/\/ but for tracing running on another processor to observe the pointer\n\/\/ but use the old value of arena_used. In this case, tracing will not\n\/\/ mark the object, even though it's reachable. However, the mutator\n\/\/ is guaranteed to execute a write barrier when it publishes the\n\/\/ pointer, so it will take care of marking the object. A general\n\/\/ consequence of this is that the garbage collector may cache the\n\/\/ value of mheap_.arena_used. (See issue #9984.)\n\/\/\n\/\/\n\/\/ Stack writes:\n\/\/\n\/\/ The compiler omits write barriers for writes to the current frame,\n\/\/ but if a stack pointer has been passed down the call stack, the\n\/\/ compiler will generate a write barrier for writes through that\n\/\/ pointer (because it doesn't know it's not a heap pointer).\n\/\/\n\/\/ One might be tempted to ignore the write barrier if slot points\n\/\/ into to the stack. Don't do it! Mark termination only re-scans\n\/\/ frames that have potentially been active since the concurrent scan,\n\/\/ so it depends on write barriers to track changes to pointers in\n\/\/ stack frames that have not been active.\n\/\/go:nowritebarrier\nfunc gcmarkwb_m(slot *uintptr, ptr uintptr) {\n\tif writeBarrierEnabled {\n\t\tif ptr != 0 && inheap(ptr) {\n\t\t\tshade(ptr)\n\t\t}\n\t}\n}\n\n\/\/ Write barrier calls must not happen during critical GC and scheduler\n\/\/ related operations. In particular there are times when the GC assumes\n\/\/ that the world is stopped but scheduler related code is still being\n\/\/ executed, dealing with syscalls, dealing with putting gs on runnable\n\/\/ queues and so forth. This code can not execute write barriers because\n\/\/ the GC might drop them on the floor. Stopping the world involves removing\n\/\/ the p associated with an m.

Entries within the\n\/\/ SigCache are keyed according to the sigHash of the signature. In the\n\/\/ scenario of a cache-hit (according to the sigHash), an additional comparison\n\/\/ of the signature, and public key will be executed in order to ensure a complete\n\/\/ match. In the occasion that two sigHashes collide, the newer sigHash will\n\/\/ simply overwrite the existing entry.\ntype sigCacheEntry struct {\n\tsig    *btcec.Signature\n\tpubKey *btcec.PublicKey\n}\n\n\/\/ SigCache implements an ECDSA signature verification cache with a randomized\n\/\/ entry eviction policy. Only valid signatures will be added to the cache. The\n\/\/ benefits of SigCache are two fold. Firstly, usage of SigCache mitigates a DoS\n\/\/ attack wherein an attack causes a victim's client to hang due to worst-case\n\/\/ behavior triggered while processing attacker crafted invalid transactions. A\n\/\/ detailed description of the mitigated DoS attack can be found here:\n\/\/ https:\/\/bitslog.wordpress.com\/2013\/01\/23\/fixed-bitcoin-vulnerability-explanation-why-the-signature-cache-is-a-dos-protection\/.\n\/\/ Secondly, usage of the SigCache introduces a signature verification\n\/\/ optimization which speeds up the validation of transactions within a block,\n\/\/ if they've already been seen and verified within the mempool.\ntype SigCache struct {\n\tsync.RWMutex\n\tvalidSigs  map[wire.ShaHash]sigCacheEntry\n\tmaxEntries uint\n}\n\n\/\/ NewSigCache creates and initializes a new instance of SigCache. Its sole\n\/\/ parameter 'maxEntries' represents the maximum number of entries allowed to\n\/\/ exist in the SigCache at any particular moment.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/\/ Database API for Go.\n\/\/\n\/\/ Terminology:\n\/\/\n\/\/ Database systems are pieces of software (usually outside of Go)\n\/\/ that allow storage and retrieval of data. We try not to imply\n\/\/ \"relational\" at the level of this API.\n\/\/\n\/\/ Database drivers are pieces of software (usually written in Go)\n\/\/ that allow Go programs to interact with database systems through\n\/\/ some query language. We try not to imply \"SQL\" at the level of\n\/\/ this API.\n\/\/\n\/\/ Goals:\n\/\/\n\/\/ The API described here is a set of conventions that should be\n\/\/ followed by database drivers. Obviously there are levels of\n\/\/ compliance, but every database driver should at least implement\n\/\/ the core of the API: the functions Version() and Open() as well\n\/\/ as the interfaces Connection, Statement, and Cursor.\npackage db\n\nimport \"os\"\n\n\/\/ Each database driver must provide a Version() function to\n\/\/ allow careful clients to configure themselves appropriately\n\/\/ for the database system in question. There are a number of\n\/\/ well-known keys in the map returned by Version():\n\/\/\n\/\/\tKey\t\tDescription\n\/\/\n\/\/\tversion\t\tgeneric version (if client\/server doesn't apply)\n\/\/\tclient\t\tclient version\n\/\/\tserver\t\tserver version\n\/\/\tprotocol\tprotocol version\n\/\/\tdriver\t\tdatabase driver version\n\/\/\n\/\/ Database driver decide which of these keys to return. For\n\/\/ example, db\/sqlite3 returns \"version\" and \"driver\"; db\/mysql\n\/\/ should probably return all keys except \"version\" instead.\n\/\/\n\/\/ Database driver can also return additional keys, provided\n\/\/ they prefix them with the package name of the driver in\n\/\/ question. The db\/sqlite3 driver, for example, returns\n\/\/ \"sqlite3.sourceid\" as well.\ntype VersionSignature func() (map[string]string, os.Error)\n\n\/\/ Each database driver must provide an Open() function to\n\/\/ establish connections to a database system. Database systems\n\/\/ require a wide variety of parameters for connections, which\n\/\/ is why the parameters to Open() are passed as a map.\n\/\/\n\/\/ XXX: THE MAP WILL BE REPLACED WITH SOME FORM OF URL IN THE\n\/\/ NEAR FUTURE. http:\/\/golang.org\/pkg\/http\/#URL\n\/\/\n\/\/ Each map entry consists of a string key and a generic value.\n\/\/ There are a number of well-known keys that apply to many (if\n\/\/ not all) database systems:\n\/\/\n\/\/\tName\t\tType\tDescription\n\/\/\n\/\/\tname\t\tstring\tthe database to connect to\n\/\/\thost\t\tstring\tthe host to connect to\n\/\/\tport\t\tint\tthe port to connect to\n\/\/\tusername\tstring\tthe user to connect as\n\/\/\tpassword\tstring\tthe password for that user\n\/\/\n\/\/ For example, the following piece of code tries to connect to\n\/\/ a MySQL database on the local machine at the default port:\n\/\/\n\/\/\tc, e := mysql.Open(\n\/\/\t\tArguments{\n\/\/\t\t\t\"name\": \"mydb\",\n\/\/\t\t\t\"username\": \"phf\",\n\/\/\t\t\t\"password\": \"somepassword\"\n\/\/\t\t}\n\/\/\t)\n\/\/\n\/\/ Note that defaults for all keys are specific to the database\n\/\/ driver in question and should be documented there.\n\/\/\n\/\/ The Open() function is free to ignore entries that it has no\n\/\/ use for. For example, the sqlite3 driver only understands\n\/\/ \"name\" and ignores the other well-known keys.\n\/\/\n\/\/ A database driver is free to introduce additional keys if\n\/\/ necessary, however those keys have to start with the package\n\/\/ name of the database driver in question. For example, the\n\/\/ sqlite3 driver supports the key \"sqlite3.vfs\".\n\/\/\n\/\/ A successful call to Open() results in a connection to the\n\/\/ database system. Specific database drivers will return\n\/\/ connection objects conforming to one or more of the following\n\/\/ interfaces which represent different levels of functionality.\ntype OpenSignature func(args map[string]interface{}) (conn Connection, err os.Error)\n\n\/\/ The most basic type of database connection.\n\/\/\n\/\/ The choice to separate Prepare() and Execute() is deliberate:\n\/\/ It leaves the database driver the most flexibilty for achieving\n\/\/ good performance without requiring additional caching schemes.\n\/\/\n\/\/ Prepare() accepts a query language string and returns\n\/\/ a precompiled statement that can be executed after any\n\/\/ remaining parameters have been bound. The format of\n\/\/ parameters in the query string is dependent on the\n\/\/ database driver in question.\n\/\/\n\/\/ Execute() accepts a precompiled statement, binds the\n\/\/ given parameters, and then executes the statement.\n\/\/ If the statement produces results, Execute() returns\n\/\/ a cursor; otherwise it returns nil. Specific database\n\/\/ driver will return cursor objects conforming to one\n\/\/ or more of the following interfaces which represent\n\/\/ different levels of functionality.\n\/\/\n\/\/ Iterate() is an experimental variant of Execute()\n\/\/ that returns a channel of Result objects instead\n\/\/ of a Cursor. XXX: Is this any good?\n\/\/\n\/\/ Close() ends the connection to the database system\n\/\/ and frees up all internal resources associated with\n\/\/ it. Note that you must close all Statement and Cursor\n\/\/ objects created through a connection before closing\n\/\/ the connection itself. After a connection has been\n\/\/ closed, no further operations are allowed on it.\ntype Connection interface {\n\tPrepare(query string) (Statement, os.Error);\n\tExecute(statement Statement, parameters ...)

We try not to imply\n\/\/ \"relational\" at the level of this API.\n\/\/\n\/\/ Database drivers are pieces of software (usually written in Go)\n\/\/ that allow Go programs to interact with database systems through\n\/\/ some query language. We try not to imply \"SQL\" at the level of\n\/\/ this API.\n\/\/\n\/\/ Goals:\n\/\/\n\/\/ The API described here is a set of conventions that should be\n\/\/ followed by database drivers. Obviously there are levels of\n\/\/ compliance, but every database driver should at least implement\n\/\/ the core of the API: the functions Version() and Open() as well\n\/\/ as the interfaces TODO Connection, Statement, and Cursor.\npackage db\n\nimport \"os\"\n\n\/\/ Database drivers must provide the Version() function to allow\n\/\/ careful clients to configure themselves appropriately for the\n\/\/ database system in question. There are a number of well-known\n\/\/ keys in the map returned by Version():\n\/\/\n\/\/\tKey\t\tDescription\n\/\/\n\/\/\tversion\t\tgeneric version (if client\/server doesn't apply)\n\/\/\tclient\t\tclient version\n\/\/\tserver\t\tserver version\n\/\/\tprotocol\tprotocol version\n\/\/\tdriver\t\tdatabase driver version\n\/\/\n\/\/ Database drivers decide which of these keys to return. For\n\/\/ example, the sqlite3 driver returns \"version\" and \"driver\";\n\/\/ the mysql driver should probably return all keys except\n\/\/ \"version\" instead.\n\/\/\n\/\/ Database drivers can also return additional keys provided\n\/\/ they prefix them with the package name of the driver. The\n\/\/ sqlite3 driver, for example, returns \"sqlite3.sourceid\" in\n\/\/ addition to \"version\" and \"driver\".\ntype VersionSignature func() (map[string]string, os.Error)\n\n\/\/ Each database driver must provide an Open() function to\n\/\/ establish connections to a database system. Database systems\n\/\/ require a wide variety of parameters for connections, which\n\/\/ is why the parameters to Open() are passed as a map.\n\/\/\n\/\/ XXX: THE MAP WILL BE REPLACED WITH SOME FORM OF URL IN THE\n\/\/ NEAR FUTURE. http:\/\/golang.org\/pkg\/http\/#URL\n\/\/\n\/\/ Each map entry consists of a string key and a generic value.\n\/\/ There are a number of well-known keys that apply to many (if\n\/\/ not all) database systems:\n\/\/\n\/\/\tName\t\tType\tDescription\n\/\/\n\/\/\tname\t\tstring\tthe database to connect to\n\/\/\thost\t\tstring\tthe host to connect to\n\/\/\tport\t\tint\tthe port to connect to\n\/\/\tusername\tstring\tthe user to connect as\n\/\/\tpassword\tstring\tthe password for that user\n\/\/\n\/\/ For example, the following piece of code tries to connect to\n\/\/ a MySQL database on the local machine at the default port:\n\/\/\n\/\/\tc, e := mysql.Open(\n\/\/\t\tArguments{\n\/\/\t\t\t\"name\": \"mydb\",\n\/\/\t\t\t\"username\": \"phf\",\n\/\/\t\t\t\"password\": \"somepassword\"\n\/\/\t\t}\n\/\/\t)\n\/\/\n\/\/ Note that defaults for all keys are specific to the database\n\/\/ driver in question and should be documented there.\n\/\/\n\/\/ The Open() function is free to ignore entries that it has no\n\/\/ use for. For example, the sqlite3 driver only understands\n\/\/ \"name\" and ignores the other well-known keys.\n\/\/\n\/\/ A database driver is free to introduce additional keys if\n\/\/ necessary, however those keys have to start with the package\n\/\/ name of the database driver in question. For example, the\n\/\/ sqlite3 driver supports the key \"sqlite3.vfs\".\n\/\/\n\/\/ A successful call to Open() results in a connection to the\n\/\/ database system.

The format of\n\/\/ parameters in the query string is dependent on the\n\/\/ database driver in question.\n\/\/\n\/\/ Execute() accepts a precompiled statement, binds the\n\/\/ given parameters, and then executes the statement.\n\/\/ If the statement produces results, Execute() returns\n\/\/ a cursor; otherwise it returns nil. Specific database\n\/\/ driver will return cursor objects conforming to one\n\/\/ or more of the following interfaces which represent\n\/\/ different levels of functionality.\n\/\/\n\/\/ Iterate() is an experimental variant of Execute()\n\/\/ that returns a channel of Result objects instead\n\/\/ of a Cursor. XXX: Is this any good?\n\/\/\n\/\/ Close() ends the connection to the database system\n\/\/ and frees up all internal resources associated with\n\/\/ it.

Think `database\/sql` for cloud products.\n\nAt the core of the Go CDK are common \"portable types\" implemented by cloud\nproviders. For example, objects of the blob.Bucket portable type can be created\nusing gcsblob.OpenBucket, s3blob.OpenBucket, or any other provider. Then, the\nblob.Bucket can be used throughout your application without worrying about\nthe underlying implementation.\n\nThe Go CDK works well with a code generator called Wire\n(https:\/\/github.com\/google\/wire\/blob\/master\/README.md). It creates\nhuman-readable code that only imports the cloud SDKs for providers you use. This\nallows the Go CDK to grow to support any number of cloud providers, without\nincreasing compile times or binary sizes, and avoiding any side effects from\n`init()` functions.\n\nFor sample applications and a tutorial, see the samples directory\n(https:\/\/github.com\/google\/go-cloud\/tree\/master\/samples).\n\n\nURLs\n\nIn addition to creating portable types via provider-specific constructors\n(e.g., creating a blob.Bucket using s3blob.OpenBucket), many portable types\ncan also be created using a URL. The scheme of the URL specifies the provider,\nand each provider implementation has code to convert the URL into the data\nneeded to call its constructor. For example, calling blob.OpenBucket with\ns3blob:\/\/my-bucket will return a blob.Bucket created using s3blob.OpenBucket.\n\nEach portable API package will document the types that it supports opening\nby URL; for example, the blob package supports Buckets, while the pubsub\npackage supports Topics and Subscriptions. Each provider implementation will\ndocument what scheme(s) it registers for, and what format of URL it expects.\n\nEach portable API package should also include an example using a URL, and\nmany providers will include provider-specific examples as well.\n\n\nURL Muxes\n\nEach portable type that's openable via URL will have a top-level function\nyou can call, like blob.OpenBucket. This top-level function uses a default\ninstance of an URLMux multiplexer to map schemes to a provider-specific\nopener for the type. For example, blob has a BucketURLOpener interface that\nproviders implement and then register using RegisterBucket.\n\nMany applications will work just fine using the default mux through the\ntop-level Open functions. However, if you want more control, you can create\nyour own URLMux and register the provider URLOpeners you need. Most providers\nwill export URLOpeners that give you more fine grained control over the\narguments needed by the constructor. In particular, portable types opened via\nURL will often use default credentials from the environment. For example, the\nAWS URL openers use the credentials saved by \"aws login\" (we don't want to\ninclude credentials in the URL itself, since they are likely to be sensitive).\n\n  - Instantiate the provider's URLOpener with the specific fields you need.\n    For example, s3blob.URLOpener{ConfigProvider: myAWSProvider} using a\n    ConfigProvider that holds explicit AWS credentials.\n  - Create your own instance of the URLMux, e.g., mymux := new(blob.URLMux).\n  - Register your custom URLOpener on your mux, e.g.,\n    mymux.RegisterBucket(s3blob.Scheme, myS3URLOpener).\n  - Now use your mux to open URLs, e.g. mymux.OpenBucket('s3:\/\/my-bucket').\n\n\nEscaping the abstraction\n\nIt is not feasible or desirable for APIs like blob.Bucket to encompass the full\nfunctionality of every provider. Rather, we intend to provide a subset of the\nmost commonly used functionality.

The bytes stay in memory unless they exceed a threshold (10MB by\ndefault), in which case they are written to a temp file.\n\nNote: Binding a file upload to os.File requires Revel to write it to a temp file\n(if it wasn’t already), making it less efficient than the other types.\n\nSlices\n\nBoth indexed and unindexed slices are supported.\n\nThese two forms are bound as unordered slices:\n\n <form>\n  <input name=\"ids\">\n  <input name=\"ids\">\n  <input name=\"ids\">\n <\/form>\n\n <form>\n  <input name=\"ids[]\">\n  <input name=\"ids[]\">\n  <input name=\"ids[]\">\n <\/form>\n\nThis is bound as an ordered slice:\n\n <form>\n  <input name=\"ids[0]\">\n  <input name=\"ids[1]\">\n  <input name=\"ids[2]\">\n <\/form>\n\nThe two forms may be combined, with unindexed elements filling any gaps between\nindexed elements.\n\n <form>\n  <input name=\"ids[]\">\n  <input name=\"ids[]\">\n  <input name=\"ids[5]\">\n <\/form>\n\nNote that if the slice element is a struct, it must use the indexed notation.\n\nStructs\n\nStructs are bound using a dot notation.  For example:\n\n <form>\n  <input name=\"user.Name\">\n  <input name=\"user.Phones[0].Label\">\n  <input name=\"user.Phones[0].Number\">\n  <input name=\"user.Phones[1].Label\">\n  <input name=\"user.Phones[1].Number\">\n <\/form>\n\nStruct fields must be exported to be bound.\n\nAdditionally, all params may be bound as members of a struct, rather than\nextracting a single field.\n\n <form>\n  <input name=\"Name\">\n  <input name=\"Phones[0].Label\">\n  <input name=\"Phones[0].Number\">\n  <input name=\"Phones[1].Label\">\n  <input name=\"Phones[1].Number\">\n <\/form>\n\n var user User\n err := bind.Request(req).All(&user)\n\n*\/\npackage bind\n<|endoftext|>"}

   var b string = \"Hello\"\n\n     assert.Equal(a, b, \"The two words should be the same.\")\n   }\n\nAssertions\n\nAssertions allow you to easily write test code, and are global funcs in the `assert` package.\nAll assertion functions take, as the first argument, the `*testing.T` object provided by the\ntesting framework. This allows the assertion funcs to write the failings and other details to\nthe correct place.\n\nEvery assertion function also takes an optional string message as the final argument,\nallowing custom error messages to be appended to the message the assertion method outputs.\n*\/\npackage assert\n<|endoftext|>"}

As stated above, these interactions are not\ndirectly handled by this package.  For more in-depth details about the\nappropriate interactions, see the official bitcoin protocol wiki entry at\nhttps:\/\/en.bitcoin.it\/wiki\/Protocol_specification.\n\nThe initial handshake consists of two peers sending each other a version message\n(MsgVersion) followed by responding with a verack message (MsgVerAck).  Both\npeers use the information in the version message (MsgVersion) to negotiate\nthings such as protocol version and supported services with each other.  Once\nthe initial handshake is complete, the following chart indicates message\ninteractions in no particular order.\n\n\tPeer A Sends                          Peer B Responds\n\t----------------------------------------------------------------------------\n\tgetaddr message (MsgGetAddr)          addr message (MsgAddr)\n\tgetblocks message (MsgGetBlocks)      inv message (MsgInv)\n\tinv message (MsgInv)                  getdata message (MsgGetData)\n\tgetdata message (MsgGetData)          block message (MsgBlock) -or-\n\t                                      tx message (MsgTx) -or-\n\t                                      notfound message (MsgNotFound)\n\tgetheaders message (MsgGetHeaders)    headers message (MsgHeaders)\n\tping message (MsgPing)                pong message (MsgHeaders)* -or-\n\t                                      (none -- Ability to send message is enough)\n\n\tNOTES:\n\t* The pong message was not added until later protocol versions as defined\n\t  in BIP0031.  The BIP0031Version constant can be used to detect a recent\n\t  enough protocol version for this purpose (version > BIP0031Version).\n\nCommon Parameters\n\nThere are several common parameters that arise when using this package to read\nand write bitcoin messages.  The following sections provide a quick overview of\nthese parameters so the next sections can build on them.\n\nProtocol Version\n\nThe protocol version should be negotiated with the remote peer at a higher\nlevel than this package via the version (MsgVersion) message exchange, however,\nthis package provides the btcwire.ProtocolVersion constant which indicates the\nlatest protocol version this package supports and is typically the value to use\nfor all outbound connections before a potentially lower protocol version is\nnegotiated.\n\nBitcoin Network\n\nThe bitcoin network is a magic number which is used to identify the start of a\nand which bitcoin network the message applies to.  This package provides the\nfollowing constants:\n\n\tbtcwire.MainNet\n\tbtcwire.TestNet\n\tbtcwire.TestNet3\n\nDetermining Message Type\n\nAs discussed in the bitcoin message overview section, this package reads\nand writes bitcoin messages using a generic interface named Message.  In\norder to determine the actual concrete type of the message, use a type\nswitch or type assertion.  An example of a type switch follows:\n\n\t\/\/ Assumes msg is already a valid concrete message such as one created\n\t\/\/ via NewMsgVersion or read via ReadMessage.\n\tswitch msg.(type) {\n\tcase *btcwire.MsgVersion:\n\t\t\/\/ The message is a pointer to a MsgVersion struct.\n\t\tfmt.Printf(\"Protocol version: %v\", msg.ProtocolVersion)\n\tcase *btcwire.MsgBlock:\n\t\t\/\/ The message is a pointer to a MsgBlock struct.\n\t\tfmt.Printf(\"Number of tx in block: %v\", msg.Header.TxnCount)\n\n\t}\n\nReading Messages\n\nIn order to unmarshall bitcoin messages from the wire, use the ReadMessage\nfunction.  It accepts any io.Reader, but typically this will be a net.Conn to\na remote node running a bitcoin peer.  Example syntax is:\n\n\t\/\/ Reads and validates the next bitcoin message from conn using the\n\t\/\/ protocol version pver and the bitcoin network btcnet.  The returns\n\t\/\/ are a btcwire.Message, a []byte which contains the unmarshalled\n\t\/\/ raw payload, and a possible error.\n\tmsg, rawPayload, err := btcwire.ReadMessage(conn, pver, btcnet)\n\tif err != nil {\n\t\t\/\/ Log and handle the error\n\t}\n\nWriting Messages\n\nIn order to marshall bitcoin messages to the wire, use the WriteMessage\nfunction.  It accepts any io.Writer, but typically this will be a net.Conn to\na remote node running a bitcoin peer.  Example syntax to request addresses\nfrom a remote peer is:\n\n\t\/\/ Create a new getaddr bitcoin message.\n\tmsg := btcwire.NewMsgGetAddr()\n\n\t\/\/ Writes a bitcoin message msg to conn using the protocol version\n\t\/\/ pver, and the bitcoin network btcnet.  The return is a possible\n\t\/\/ error.\n\terr := btcwire.WriteMessage(conn, msg, pver, btcnet)\n\tif err != nil {\n\t\t\/\/ Log and handle the error\n\t}\n\nErrors\n\nMost errors returned by this package are either the raw errors provided by\nunderlying calls to read\/write from streams, or raw strings that describe\nthe error.  See the documentation of each function for any exceptions.  NOTE:\nThis will change soon as the package should return errors that can be\nprogramatically tested.\n\nBitcoin Improvement Proposals\n\nThis package includes spec changes outlined by the following BIPs:\n\n\t\tBIP0031 (https:\/\/en.bitcoin.it\/wiki\/BIP_0031)\n\t\tBIP0035 (https:\/\/en.bitcoin.it\/wiki\/BIP_0035)\n\nOther important information\n\nThe package does not yet implement BIP0037 (https:\/\/en.bitcoin.it\/wiki\/BIP_0037)\nand therefore does not recognize filterload, filteradd, filterclear, or\nmerkleblock messages.\n*\/\npackage btcwire\n<commit_msg>Fix a minor typo in the package overview doco.<commit_after>\/\/ Copyright (c) 2013 Conformal Systems LLC.\n\/\/ Use of this source code is governed by an ISC\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage btcwire implements the bitcoin wire protocol.\n\nFor the complete details of the bitcoin protocol, see the official wiki entry\nat https:\/\/en.bitcoin.it\/wiki\/Protocol_specification.

Both\npeers use the information in the version message (MsgVersion) to negotiate\nthings such as protocol version and supported services with each other.  Once\nthe initial handshake is complete, the following chart indicates message\ninteractions in no particular order.\n\n\tPeer A Sends                          Peer B Responds\n\t----------------------------------------------------------------------------\n\tgetaddr message (MsgGetAddr)          addr message (MsgAddr)\n\tgetblocks message (MsgGetBlocks)      inv message (MsgInv)\n\tinv message (MsgInv)                  getdata message (MsgGetData)\n\tgetdata message (MsgGetData)          block message (MsgBlock) -or-\n\t                                      tx message (MsgTx) -or-\n\t                                      notfound message (MsgNotFound)\n\tgetheaders message (MsgGetHeaders)    headers message (MsgHeaders)\n\tping message (MsgPing)                pong message (MsgHeaders)* -or-\n\t                                      (none -- Ability to send message is enough)\n\n\tNOTES:\n\t* The pong message was not added until later protocol versions as defined\n\t  in BIP0031.  The BIP0031Version constant can be used to detect a recent\n\t  enough protocol version for this purpose (version > BIP0031Version).\n\nCommon Parameters\n\nThere are several common parameters that arise when using this package to read\nand write bitcoin messages.  The following sections provide a quick overview of\nthese parameters so the next sections can build on them.\n\nProtocol Version\n\nThe protocol version should be negotiated with the remote peer at a higher\nlevel than this package via the version (MsgVersion) message exchange, however,\nthis package provides the btcwire.ProtocolVersion constant which indicates the\nlatest protocol version this package supports and is typically the value to use\nfor all outbound connections before a potentially lower protocol version is\nnegotiated.\n\nBitcoin Network\n\nThe bitcoin network is a magic number which is used to identify the start of a\nmessage and which bitcoin network the message applies to.  This package provides\nthe following constants:\n\n\tbtcwire.MainNet\n\tbtcwire.TestNet\n\tbtcwire.TestNet3\n\nDetermining Message Type\n\nAs discussed in the bitcoin message overview section, this package reads\nand writes bitcoin messages using a generic interface named Message.  In\norder to determine the actual concrete type of the message, use a type\nswitch or type assertion.  An example of a type switch follows:\n\n\t\/\/ Assumes msg is already a valid concrete message such as one created\n\t\/\/ via NewMsgVersion or read via ReadMessage.\n\tswitch msg.(type) {\n\tcase *btcwire.MsgVersion:\n\t\t\/\/ The message is a pointer to a MsgVersion struct.\n\t\tfmt.Printf(\"Protocol version: %v\", msg.ProtocolVersion)\n\tcase *btcwire.MsgBlock:\n\t\t\/\/ The message is a pointer to a MsgBlock struct.\n\t\tfmt.Printf(\"Number of tx in block: %v\", msg.Header.TxnCount)\n\n\t}\n\nReading Messages\n\nIn order to unmarshall bitcoin messages from the wire, use the ReadMessage\nfunction.  It accepts any io.Reader, but typically this will be a net.Conn to\na remote node running a bitcoin peer.  Example syntax is:\n\n\t\/\/ Reads and validates the next bitcoin message from conn using the\n\t\/\/ protocol version pver and the bitcoin network btcnet.  The returns\n\t\/\/ are a btcwire.Message, a []byte which contains the unmarshalled\n\t\/\/ raw payload, and a possible error.\n\tmsg, rawPayload, err := btcwire.ReadMessage(conn, pver, btcnet)\n\tif err != nil {\n\t\t\/\/ Log and handle the error\n\t}\n\nWriting Messages\n\nIn order to marshall bitcoin messages to the wire, use the WriteMessage\nfunction.  It accepts any io.Writer, but typically this will be a net.Conn to\na remote node running a bitcoin peer.  Example syntax to request addresses\nfrom a remote peer is:\n\n\t\/\/ Create a new getaddr bitcoin message.\n\tmsg := btcwire.NewMsgGetAddr()\n\n\t\/\/ Writes a bitcoin message msg to conn using the protocol version\n\t\/\/ pver, and the bitcoin network btcnet.  The return is a possible\n\t\/\/ error.\n\terr := btcwire.WriteMessage(conn, msg, pver, btcnet)\n\tif err != nil {\n\t\t\/\/ Log and handle the error\n\t}\n\nErrors\n\nMost errors returned by this package are either the raw errors provided by\nunderlying calls to read\/write from streams, or raw strings that describe\nthe error.  See the documentation of each function for any exceptions.  NOTE:\nThis will change soon as the package should return errors that can be\nprogramatically tested.\n\nBitcoin Improvement Proposals\n\nThis package includes spec changes outlined by the following BIPs:\n\n\t\tBIP0031 (https:\/\/en.bitcoin.it\/wiki\/BIP_0031)\n\t\tBIP0035 (https:\/\/en.bitcoin.it\/wiki\/BIP_0035)\n\nOther important information\n\nThe package does not yet implement BIP0037 (https:\/\/en.bitcoin.it\/wiki\/BIP_0037)\nand therefore does not recognize filterload, filteradd, filterclear, or\nmerkleblock messages.\n*\/\npackage btcwire\n<|endoftext|>"}
{"text":"<commit_before>\/*\nSprig: Template functions for Go.\n\nThis package contains a number of utility functions for working with data\ninside of Go `html\/template` and `text\/template` files.\n\nTo add these functions, use the `template.Funcs()` method:\n\n\tt := templates.New(\"foo\").Funcs(sprig.FuncMap())\n\nNote that you should add the function map before you parse any template files.\n\n\tIn several cases, Sprig reverses the order of arguments from the way they\n\tappear in the standard library. This is to make it easier to pipe\n\targuments into functions.\n\nDate Functions\n\n\t- date FORMAT TIME: Format a date, where a date is an integer type or a time.Time type, and\n\t  format is a time.Format formatting string.\n\t- dateModify: Given a date, modify it with a duration: `date_modify \"-1.5h\" now`. If the duration doesn't\n\tparse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.\n\t- now: Current time.Time, for feeding into date-related functions.\n\t- htmlDate TIME: Format a date for use in the value field of an HTML \"date\" form element.\n\t- dateInZone FORMAT TIME TZ: Like date, but takes three arguments: format, timestamp,\n\t  timezone.\n\t- htmlDateInZone TIME TZ: Like htmlDate, but takes two arguments: timestamp,\n\t  timezone.\n\nString Functions\n\n\t- abbrev: Truncate a string with ellipses. `abbrev 5 \"hello world\"` yields \"he...\"\n\t- abbrevboth: Abbreviate from both sides, yielding \"...lo wo...\"\n\t- trunc: Truncate a string (no suffix). `trunc 5 \"Hello World\"` yields \"hello\".\n\t- trim: strings.TrimSpace\n\t- trimAll: strings.Trim, but with the argument order reversed `trimAll \"$\" \"$5.00\"` or `\"$5.00 | trimAll \"$\"`\n\t- trimSuffix: strings.TrimSuffix, but with the argument order reversed: `trimSuffix \"-\" \"ends-with-\"`\n\t- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix \"$\" \"$5\"`\n\t- upper: strings.ToUpper\n\t- lower: strings.ToLower\n\t- nospace: Remove all space characters from a string. `nospace \"h e l l o\"` becomes \"hello\"\n\t- title: strings.Title\n\t- untitle: Remove title casing\n\t- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)\n\t- substr: Given string, start, and length, return a substr.\n\t- initials: Given a multi-word string, return the initials. `initials \"Matt Butcher\"` returns \"MB\"\n\t- randAlphaNum: Given a length, generate a random alphanumeric sequence\n\t- randAlpha: Given a length, generate an alphabetic string\n\t- randAscii: Given a length, generate a random ASCII string (symbols included)\n\t- randNumeric: Given a length, generate a string of digits.\n\t- wrap: Force a line wrap at the given width. `wrap 80 \"imagine a longer string\"`\n\t- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, \"<br>\", $html`\n\t- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)\n\t- hasPrefix: strings.hasPrefix, but with the arguments switched\n\t- hasSuffix: strings.hasSuffix, but with the arguments switched\n\t- quote: Wrap string(s) in double quotation marks, escape the contents by adding '\\' before '\"'.\n\t- squote: Wrap string(s) in double quotation marks, does not escape content.\n\t- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.\n\t- indent: Indent a string using space characters. `indent 4 \"foo\\nbar\"` produces \"    foo\\n    bar\"\n\t- replace: Replace an old with a new in a string: `$name | replace \" \" \"-\"`\n\t- plural: Choose singular or plural based on length: `len $fish | plural \"one anchovy\" \"many anchovies\"`\n\t- sha256sum: Generate a hex encoded sha256 hash of the input\n\t- toString: Convert something to a string\n\nString Slice Functions:\n\n\t- join: strings.Join, but as `join SEP SLICE`\n\t- split: strings.Split, but as `split SEP STRING`. The results are returned\n\t  as a map with the indexes set to _N, where N is an integer starting from 0.\n\t  Use it like this: `{{$v := \"foo\/bar\/baz\" | split \"\/\"}}{{$v._0}}` (Prints `foo`)\n    - splitList: strings.Split, but as `split SEP STRING`.

Used like this: trim \"   \"| default \"empty\".\n\t  Since trim produces an empty string, the default value is returned. For\n\t  things with a length (strings, slices, maps), len(0) will trigger the default.\n\t  For numbers, the value 0 will trigger the default. For booleans, false will\n\t  trigger the default. For structs, the default is never returned (there is\n\t  no clear empty condition). For everything else, nil value triggers a default.\n\t- empty: Return true if the given value is the zero value for its type.\n\t  Caveats: structs are always non-empty. This should match the behavior of\n\t  {{if pipeline}}, but can be used inside of a pipeline.\n\t- coalesce: Given a list of items, return the first non-empty one.\n\t  This follows the same rules as 'empty'. '{{ coalesce .someVal 0 \"hello\" }}`\n\t  will return `.someVal` if set, or else return \"hello\". The 0 is skipped\n\t  because it is an empty value.\n\t- compact: Return a copy of a list with all of the empty values removed.\n\t  'list 0 1 2 \"\" | compact' will return '[1 2]'\n\nOS:\n\t- env: Resolve an environment variable\n\t- expandenv: Expand a string through the environment\n\nFile Paths:\n\t- base: Return the last element of a path. https:\/\/golang.org\/pkg\/path#Base\n\t- dir: Remove the last element of a path. https:\/\/golang.org\/pkg\/path#Dir\n\t- clean: Clean a path to the shortest equivalent name.

So\n\t  a pointer to type `Foo` will be `*Foo`.\n\t- typeIs: Compares an interface with a string name, and returns true if they match.\n\t  Note that a pointer will not match a reference. For example `*Foo` will not\n\t  match `Foo`.\n\t- typeIsLike: Compares an interface with a string name and returns true if\n\t  the interface is that `name` or that `*name`. In other words, if the given\n\t  value matches the given type or is a pointer to the given type, this returns\n\t  true.\n\t- kindOf: Takes an interface and returns a string representation of its kind.\n\t- kindIs: Returns true if the given string matches the kind of the given interface.\n\n\tNote: None of these can test whether or not something implements a given\n\tinterface, since doing so would require compiling the interface in ahead of\n\ttime.\n\nData Structures:\n\n\t- tuple: Takes an arbitrary list of items and returns a slice of items. Its\n\t  tuple-ish properties are mainly gained through the template idiom, and not\n\t  through an API provided here. WARNING: The implementation of tuple will\n\t  change in the future.\n\t- list: An arbitrary ordered list of items. (This is prefered over tuple.)\n\t- dict: Takes a list of name\/values and returns a map[string]interface{}.\n\t  The first parameter is converted to a string and stored as a key, the\n\t  second parameter is treated as the value. And so on, with odds as keys and\n\t  evens as values. If the function call ends with an odd, the last key will\n\t  be assigned the empty string. Non-string keys are converted to strings as\n\t  follows: []byte are converted, fmt.Stringers will have String() called.\n\t  errors will have Error() called. All others will be passed through\n\t  fmt.Sprtinf(\"%v\").\n\nLists Functions:\n\nThese are used to manipulate lists: '{{ list 1 2 3 | reverse | first }}'\n\n\t- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'\n\t- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'\n\t- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'\n\t- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'\n\t- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'\n\t- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.\n\t- reverse: Reverse the items in a list.\n\t- uniq: Remove duplicates from a list.\n\t- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'\n\t- has: Return 'true' if the item is found in the list: 'has \"foo\" $list' will return 'true' if the list contains \"foo\"\n\nDict Functions:\n\nThese are used to manipulate dicts.\n\n\t- set: Takes a dict, a key, and a value, and sets that key\/value pair in\n\t  the dict. `set $dict $key $value`. For convenience, it returns the dict,\n\t  even though the dict was modified in place.\n\t- unset: Takes a dict and a key, and deletes that key\/value pair from the\n\t  dict. `unset $dict $key`. This returns the dict for convenience.\n\t- hasKey: Takes a dict and a key, and returns boolean true if the key is in\n\t  the dict.\n\t- pluck: Given a key and one or more maps, get all of the values for that key.\n\t- keys: Get an array of all of the keys in a dict.\n\t- pick: Select just the given keys out of the dict, and return a new dict.\n\t- omit: Return a dict without the given keys.\n\nMath Functions:\n\nInteger functions will convert integers of any width to `int64`. If a\nstring is passed in, functions will attempt to convert with\n`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.\n\n\t- add1: Increment an integer by 1\n\t- add: Sum an arbitrary number of integers\n\t- sub: Subtract the second integer from the first\n\t- div: Divide the first integer by the second\n\t- mod: Module of first integer divided by second\n\t- mul: Multiply integers\n\t- max: Return the biggest of a series of one or more integers\n\t- min: Return the smallest of a series of one or more integers\n\t- biggest: DEPRECATED. Return the biggest of a series of one or more integers\n\nCrypto Functions:\n\n\t- genPrivateKey: Generate a private key for the given cryptosystem. If no\n\t  argument is supplied, by default it will generate a private key using\n\t  the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.\n\t- derivePassword: Derive a password from the given parameters according to the [\"Master Password\" algorithm](http:\/\/masterpasswordapp.com\/algorithm.html)\n\t  Given parameters (in order) are:\n          `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,\n           `user`, and `site`\n\nSemVer Functions:\n\nThese functions provide version parsing and comparisons for SemVer 2 version\nstrings.\n\n\t- semver: Parse a semantic version and return a Version object.\n\t- semverCompare: Compare a SemVer range to a particular version.\n*\/\npackage sprig\n<commit_msg>Fix minor indentation issues<commit_after>\/*\nSprig: Template functions for Go.\n\nThis package contains a number of utility functions for working with data\ninside of Go `html\/template` and `text\/template` files.\n\nTo add these functions, use the `template.Funcs()` method:\n\n\tt := templates.New(\"foo\").Funcs(sprig.FuncMap())\n\nNote that you should add the function map before you parse any template files.\n\n\tIn several cases, Sprig reverses the order of arguments from the way they\n\tappear in the standard library.

'list 1 2 3 | first' prints '1'\n\t- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'\n\t- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'\n\t- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'\n\t- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'\n\t- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.\n\t- reverse: Reverse the items in a list.\n\t- uniq: Remove duplicates from a list.\n\t- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'\n\t- has: Return 'true' if the item is found in the list: 'has \"foo\" $list' will return 'true' if the list contains \"foo\"\n\nDict Functions:\n\nThese are used to manipulate dicts.\n\n\t- set: Takes a dict, a key, and a value, and sets that key\/value pair in\n\t  the dict. `set $dict $key $value`. For convenience, it returns the dict,\n\t  even though the dict was modified in place.\n\t- unset: Takes a dict and a key, and deletes that key\/value pair from the\n\t  dict. `unset $dict $key`. This returns the dict for convenience.\n\t- hasKey: Takes a dict and a key, and returns boolean true if the key is in\n\t  the dict.\n\t- pluck: Given a key and one or more maps, get all of the values for that key.\n\t- keys: Get an array of all of the keys in a dict.\n\t- pick: Select just the given keys out of the dict, and return a new dict.\n\t- omit: Return a dict without the given keys.\n\nMath Functions:\n\nInteger functions will convert integers of any width to `int64`. If a\nstring is passed in, functions will attempt to convert with\n`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.\n\n\t- add1: Increment an integer by 1\n\t- add: Sum an arbitrary number of integers\n\t- sub: Subtract the second integer from the first\n\t- div: Divide the first integer by the second\n\t- mod: Module of first integer divided by second\n\t- mul: Multiply integers\n\t- max: Return the biggest of a series of one or more integers\n\t- min: Return the smallest of a series of one or more integers\n\t- biggest: DEPRECATED. Return the biggest of a series of one or more integers\n\nCrypto Functions:\n\n\t- genPrivateKey: Generate a private key for the given cryptosystem. If no\n\t  argument is supplied, by default it will generate a private key using\n\t  the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.\n\t- derivePassword: Derive a password from the given parameters according to the [\"Master Password\" algorithm](http:\/\/masterpasswordapp.com\/algorithm.html)\n\t  Given parameters (in order) are:\n          `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,\n           `user`, and `site`\n\nSemVer Functions:\n\nThese functions provide version parsing and comparisons for SemVer 2 version\nstrings.\n\n\t- semver: Parse a semantic version and return a Version object.\n\t- semverCompare: Compare a SemVer range to a particular version.\n*\/\npackage sprig\n<|endoftext|>"}

Since configurator is built on top of Viper the\n\/\/ same source precedence is applicable.\n\/\/\n\/\/ The priority of config sources is the following:\n\/\/ 1. Overrides, or setting the config struct field directly.\n\/\/ 2. Flags - note that github.com\/spf13\/pflag is used  in lieu of the standard flag package.\n\/\/ 3. Environment variables.\n\/\/ 4. Configuration file values.\n\/\/ 5.

For example: \"otto apps list -h\" will show the\n\/\/     help for \"apps list\" but \"otto apps -h\" will show it for \"apps\".\n\/\/     In the normal CLI, only the first subcommand is used.\n\/\/\n\/\/   * The help flag will list any subcommands that a command takes\n\/\/     as well as the command's help itself. If there are no subcommands,\n\/\/     it will note this. If the CLI itself has no subcommands, this entire\n\/\/     section is omitted.\n\/\/\n\/\/   * Any parent commands that don't exist are automatically created as\n\/\/     no-op commands that just show help for other subcommands. For example,\n\/\/     if you only register \"foo bar\", then \"foo\" is automatically created.\n\/\/\ntype CLI struct {\n\t\/\/ Args is the list of command-line arguments received excluding\n\t\/\/ the name of the app. For example, if the command \".\/cli foo bar\"\n\t\/\/ was invoked, then Args should be []string{\"foo\", \"bar\"}.\n\tArgs []string\n\n\t\/\/ Commands is a mapping of subcommand names to a factory function\n\t\/\/ for creating that Command implementation. If there is a command\n\t\/\/ with a blank string \"\", then it will be used as the default command\n\t\/\/ if no subcommand is specified.\n\t\/\/\n\t\/\/ If the key has a space in it, this will create a nested subcommand.\n\t\/\/ For example, if the key is \"foo bar\", then to access it our CLI\n\t\/\/ must be accessed with \".\/cli foo bar\". See the docs for CLI for\n\t\/\/ notes on how this changes some other behavior of the CLI as well.\n\tCommands map[string]CommandFactory\n\n\t\/\/ Name defines the name of the CLI.\n\tName string\n\n\t\/\/ Version of the CLI.\n\tVersion string\n\n\t\/\/ HelpFunc and HelpWriter are used to output help information, if\n\t\/\/ requested.\n\t\/\/\n\t\/\/ HelpFunc is the function called to generate the generic help\n\t\/\/ text that is shown if help must be shown for the CLI that doesn't\n\t\/\/ pertain to a specific command.\n\t\/\/\n\t\/\/ HelpWriter is the Writer where the help text is outputted to.

Most errors will also be inoccuous (clients dropping\nconnections, etc.), and adminsock should continue operating with no\nintervention.\n\nHowever, if Msg.Err is not nil and Msg.Txt is \"ENOLISTENER\", then a\nlocal networking error has occurred and the adminsock's listener\nsocket has gone away. If this happens, your adminsock instance is no\nlonger viable; clean it up and spawn a new one. You should, at worst,\ndrop a few connection attempts.\n\nMsgr is a buffered channel, capable of holding 32 Msgs. Most writes to\nit, however, will silently fail instead of blocking (which would lead\nto deadlock should a shutdown be called for). The one exception to\nthis is the ENOLISTENER message, which will block.\n\nSHUTDOWN AND CLEANUP\n\nTo halt an adminsock instance, call\n\n    as.Quit()\n\nThis will immediately stop the instance from accepting new\nconnections, and will then wait for all existing connections to\nterminate.\n\nBe aware that if the instance was created with very long connection\ntimeouts (or no timeout at all), then Quit() will block for an\nindeterminate length of time.\n\nOnce Quit() returns, the instance will have no more execution threads\nand will exist only as a reference to an Adminsock struct.\n\nIf you are recovering from a ENOLISTENER condition, it's safe at this\npoint to spawn a new instance:\n\n    case msg := <- as.Msgr:\n        if msg.Err != nil && msg.Txt == \"ENOLISTENER\" {\n            as.Quit()\n            as = adminsock.New(d, 0)\n        }\n\n*\/\npackage adminsock\n<commit_msg>doc wip<commit_after>\/*\nPackage adminsock provides a Unix domain socket -- with builtin\nrequest dispatch -- for administration of a daemon.\n\nCOMMAND DISPATCH\n\nConsider this example, showing an instance of adminsock being setup as\nan echo server.\n\n    func hollaback(s []string) ([]byte, error){\n        return []byte(strings.Join(s, \" \")), nil\n    }\n    \n    func main() {\n        d := make(adminsock.Dispatch)\n        d[\"echo\"] = hollaback\n        as, err := adminsock.New(\"mysockname\", d, 0)\n        \/\/ if err != nil, adminsock is up and listening\n        ...\n    }\n\nA function is defined for each request which adminsock will handle\n(here there is just the one, hollaback()).\n\nThese functions are added to an instance of adminsock.Dispatch, which\nis passed to adminsock.New().

In addition, a config struct can be created by `ParseConfig` and modified before establishing the connection with\n`ConnectConfig` to configure settings such as tracing that cannot be configured with a connection string.\n\nConnection Pool\n\n`*pgx.Conn` represents a single connection to the database and is not concurrency safe. Use sub-package pgxpool for a\nconcurrency safe connection pool.\n\nQuery Interface\n\npgx implements Query in the familiar database\/sql style. However, pgx provides generic functions such as CollectRows and\nForEachRow that are a simpler and safer way of processing rows than manually calling rows.Next(), rows.Scan, and\nrows.Err().\n\nCollectRows can be used collect all returned rows into a slice.\n\n    rows, _ := conn.Query(context.Background(), \"select generate_series(1,$1)\", 5)\n    numbers, err := pgx.CollectRows(rows, pgx.RowTo[int32])\n    if err != nil {\n      return err\n    }\n    \/\/ numbers => [1 2 3 4 5]\n\nForEachRow can be used to execute a callback function for every row. This is often easier than iterating over rows\ndirectly.\n\n    var sum, n int32\n    rows, _ := conn.Query(context.Background(), \"select generate_series(1,$1)\", 10)\n    _, err := pgx.ForEachRow(rows, []any{&n}, func(pgx.QueryFuncRow) error {\n      sum += n\n      return nil\n    })\n    if err != nil {\n      return err\n    }\n\npgx also implements QueryRow in the same style as database\/sql.\n\n    var name string\n    var weight int64\n    err := conn.QueryRow(context.Background(), \"select name, weight from widgets where id=$1\", 42).Scan(&name, &weight)\n    if err != nil {\n        return err\n    }\n\nUse Exec to execute a query that does not return a result set.\n\n    commandTag, err := conn.Exec(context.Background(), \"delete from widgets where id=$1\", 42)\n    if err != nil {\n        return err\n    }\n    if commandTag.RowsAffected() != 1 {\n        return errors.New(\"No row found to delete\")\n    }\n\nPostgreSQL Data Types\n\nThe package pgtype provides extensive and customizable support for converting Go values to and from PostgreSQL values\nincluding array and composite types. See that package's documentation for details.\n\nTransactions\n\nTransactions are started by calling Begin.\n\n    tx, err := conn.Begin(context.Background())\n    if err != nil {\n        return err\n    }\n    \/\/ Rollback is safe to call even if the tx is already closed, so if\n    \/\/ the tx commits successfully, this is a no-op\n    defer tx.Rollback(context.Background())\n\n    _, err = tx.Exec(context.Background(), \"insert into foo(id) values (1)\")\n    if err != nil {\n        return err\n    }\n\n    err = tx.Commit(context.Background())\n    if err != nil {\n        return err\n    }\n\nThe Tx returned from Begin also implements the Begin method. This can be used to implement pseudo nested transactions.\nThese are internally implemented with savepoints.\n\nUse BeginTx to control the transaction mode.\n\nBeginFunc and BeginTxFunc are functions that begin a transaction, execute a function, and commit or rollback the\ntransaction depending on the return value of the function. These can be simpler and less error prone to use.\n\n    err = pgx.BeginFunc(context.Background(), conn, func(tx pgx.Tx) error {\n        _, err := tx.Exec(context.Background(), \"insert into foo(id) values (1)\")\n        return err\n    })\n    if err != nil {\n        return err\n    }\n\nPrepared Statements\n\nPrepared statements can be manually created with the Prepare method. However, this is rarely necessary because pgx\nincludes an automatic statement cache by default. Queries run through the normal Query, QueryRow, and Exec functions are\nautomatically prepared on first execution and the prepared statement is reused on subsequent executions. See ParseConfig\nfor information on how to customize or disable the statement cache.\n\nCopy Protocol\n\nUse CopyFrom to efficiently insert multiple rows at a time using the PostgreSQL copy protocol. CopyFrom accepts a\nCopyFromSource interface. If the data is already in a [][]any use CopyFromRows to wrap it in a CopyFromSource interface.\nOr implement CopyFromSource to avoid buffering the entire data set in memory.\n\n    rows := [][]any{\n        {\"John\", \"Smith\", int32(36)},\n        {\"Jane\", \"Doe\", int32(29)},\n    }\n\n    copyCount, err := conn.CopyFrom(\n        context.Background(),\n        pgx.Identifier{\"people\"},\n        []string{\"first_name\", \"last_name\", \"age\"},\n        pgx.CopyFromRows(rows),\n    )\n\nWhen you already have a typed array using CopyFromSlice can be more convenient.\n\n    rows := []User{\n        {\"John\", \"Smith\", 36},\n        {\"Jane\", \"Doe\", 29},\n    }\n\n    copyCount, err := conn.CopyFrom(\n        context.Background(),\n        pgx.Identifier{\"people\"},\n        []string{\"first_name\", \"last_name\", \"age\"},\n        pgx.CopyFromSlice(len(rows), func(i int) ([]any, error) {\n            return []any{rows[i].FirstName, rows[i].LastName, rows[i].Age}, nil\n        }),\n    )\n\nCopyFrom can be faster than an insert with as few as 5 rows.\n\nListen and Notify\n\npgx can listen to the PostgreSQL notification system with the `Conn.WaitForNotification` method. It blocks until a\nnotification is received or the context is canceled.\n\n    _, err := conn.Exec(context.Background(), \"listen channelname\")\n    if err != nil {\n        return nil\n    }\n\n    if notification, err := conn.WaitForNotification(context.Background()); err != nil {\n        \/\/ do something with notification\n    }\n\n\nTracing and Logging\n\npgx supports tracing by setting ConnConfig.Tracer.\n\nIn addition, the tracelog package provides the TraceLog type which lets a traditional logger act as a Tracer.\n\nLower Level PostgreSQL Functionality\n\npgx is implemented on top of github.com\/jackc\/pgconn a lower level PostgreSQL driver. The Conn.PgConn() method can be\nused to access this lower layer.\n\nPgBouncer\n\nBy default pgx automatically uses prepared statements. Prepared statements are incompaptible with PgBouncer. This can be\ndisabled by setting a different QueryExecMode in ConnConfig.DefaultQueryExecMode.\n*\/\npackage pgx\n<commit_msg>More doc tweaks<commit_after>\/\/ Package pgx is a PostgreSQL database driver.\n\/*\npgx provides a native PostgreSQL driver and can act as a database\/sql driver.

It's the result of\nabout 20 hours of screwing around. I meant to keep it shorter, but\nI started to have too much fun.\n\n\"Morally\" correct means that I intend this to demonstrate a point about\nAPI and language design, and that I don't necessarily intend this to\nhave any other utility.\n\nHowever, as I developed my ideas this turned into a potentially\nlegitimately useful library, because instead of expressing all\nthe interpolations in terms of strings, they are all expressed in\nterms of io.Writers. Since this library also permits inputting\nthe strings to be interpolated in the form of io.Readers, this means\nthat this entire library is fully capable of string interpolation in\nthe middle of streams, not just strings. Or, if you prefer, this is\na *stream* interpolator.\n\nThis documentation focuses on usage; for the reasoning behind the\ndesign, consult the blog post.\n\nUsing String Interpolators\n\nTo use this package, create an interpolator object:\n\n    i := strinterp.NewInterpolator()\n\nYou can then use it to interpolate strings. The simplest case is\nconcatenation:\n\n    concated, err := i.InterpStr(\"concated: %RAW;%RAW;\", str1, str2)\n\nSee the blog post for a discussion of why this is deliberately a bit\nheavyweight and *designed* to call attention to the use of \"RAW\".\n\nThe \"format string\", the first element of the call, has the following\nsyntax:\n\n    * Begins with %, ends with unescaped ;\n    * Begins with the formatter\/encoder name\n    * Which may be followed by a colon, then args for that formatter\n    * Which may then be followed by a pipe, and further specifications\n      of encoders with optional arguments\n\nYou may backslash-escape any of the pipe, colon, or semicolon to pass them\nthrough as arguments to the formatter\/encoder, or backslash itself to pass\nit through. To emit a raw %, use \"%%;\".\n\nHere is an example of a format string that uses all these features:\n\n    result, err := i.InterpStr(\"copy and paste: %json:nohtml|base64:url;\", obj)\n\nThis will result in the standard encoding\/json encoding being used on the\nobj, then it will be converted to base64 using the encoding\/base64\nURLEncoding specification. You can continue piping to further encoders\nindefinitely.\n\nThere are two different kinds of interpolators you can write, formatters\nand encoders.\n\nFormatters\n\nA \"formatter\" is a routine that takes a Go value of some sort and\nconverts it to some bytes to be written out via a provided io.Writer.\nA formatter has the function signature defined by the Formatter type,\nwhich is:\n\n    func (w io.Writer, arg interface{}, params []byte) error\n\nWhen called, the function should first examine the parameters. If it\ndoesn't like the parameters, it should return ErrUnknownArguments,\nproperly filled out. (Note: It is important to be strict on the\nparameters; if they don't make perfect sense, this is your only chance\nto warn a user about that.) It should then take the arg and write it\nout to the io.Writer in whatever manner makes sense, then return either\nthe error obtained during writing or nil if it was fully successful.\n\nSee the Formatter documentation below for more gritty details.\n\nA formatter can only appear in the first position of a format\nspecification.\n\nEncoders\n\nAn \"encoder\" is a routine that receives incoming io.Writer requests,\nmodifies them in a suitable manner, and passes them down to the next\nio.Writer in the chain. In other words it takes []byte and generates\nfurther []byte from them.\n\nSee the Encoder documentation below for more gritty details. See\nexamples.go for examples that the library ships with.\n\nConfiguring Your Interpolators\n\nTo configure your interpolator, you will need to add additional\nformatters and encoders to the interpolator so it is aware of them.\nNewInterpolator will return a bare *Interpolator with only the \"RAW\"\nencoder. A DefaultInterpolator is also provided that comes preconfigured\nfor some HTML- and JSON-type-tasks. Consulting the \"examples.go\" file\nin the godoc file listing below will highlight these formatters\nand interpolators for your cribbing convenience.\n\nUse the AddFormatter and AddEncoder functions to add these to your\ninterpolator to configure it.\n\n(Since I find people often get a sort of mental block around this,\nremember that, for instance, even though I provide you a default JSON\nstreamer based on the standard encoding\/json library, if you have\nsomething else you prefer, you can always specify a *different*\njson formatter for your own usage.)\n\nOnce configured, for maximum utility I recommend putting string\ninterpolation into your environment object. See\nhttp:\/\/www.jerf.org\/iri\/post\/2929 .\n\nSecurity Note\n\nThis is true of all string interpolators, but even more so of\nstrinterp. You MUST NOT feed user input as the interpolation source\nstring. In fact I'd suggest that one could make a good case that the first\nparameter to strinterp should always be a constant string in the source\ncode base, and if I were going to write a local validation routine to plug\ninto go vet or something I'd probably add that as a rule.\n\nAgain, let me emphasize, this is NOT special to strinterp. You shouldn't\nlet users feed into the first parameter of fmt.Sprintf, or any other such\nstring, in any language for that matter. It's possible some are \"safe\" to\ndo that in, but given the wide range of havoc done over the years by\nletting users control interpolation strings, I would just recommend against\nit unconditionally.\n\nCare should also be taken in the construction of filters. If they get much\n\"smarter\" than a for loop iterating over bytes\/runes and doing \"something\" with\nthem, you're starting to ask for trouble if user input passes through\nthem. Generally the entire point of strinterp is to handle potentially\nuntrusted input in a safe manner, so if you start \"interpreting\" user input\nyou could be creating openings for attackers.\n\n*\/\npackage strinterp\n<commit_msg>Hopefully final changes to the docs.<commit_after>\/*\n\nPackage strinterp provides a demonstration of morally correct string\ninterpolation.\n\nThis package was created in support of a blog post.

Consulting the \"examples.go\" file\nin the godoc file listing below will highlight these formatters\nand interpolators for your cribbing convenience.\n\nUse the AddFormatter and AddEncoder functions to add these to your\ninterpolator to configure it.\n\n(Since I find people often get a sort of mental block around this,\nremember that, for instance, even though I provide you a default JSON\nstreamer based on the standard encoding\/json library, if you have\nsomething else you prefer, you can always specify a *different*\njson formatter for your own usage.)\n\nOnce configured, for maximum utility I recommend putting string\ninterpolation into your environment object. See\nhttp:\/\/www.jerf.org\/iri\/post\/2929 .\n\nDirect Encoder Usage\n\nIt is also possible to directly use the Encoders, as their type signature\ntends to imply (note how you don't have to pass them any *Interpolator\nor any other context). Ideally you instantiate a WriterStack around your\ntarget io.Writer and .Push encoders on top of that, as WriterStack handles\nsome corner cases around Encoders that want to be \"Close\"d, then call\n.Finish() on the WriterStack when done, which DOES NOT close the\nunderlying io.Writer. This is probably the maximally-performing way to\ndo this sort of encoding in a stream.\n\nSecurity Note\n\nThis is true of all string interpolators, but even more so of\nstrinterp since it can be hooked up to arbitrary formatters and\nencoders. You MUST NOT feed user input as the interpolation source\nstring. In fact I'd suggest that one could make a good case that the first\nparameter to strinterp should always be a constant string in the source\ncode base, and if I were going to write a local validation routine to plug\ninto go vet or something I'd probably add that as a rule.\n\nAgain, let me emphasize, this is NOT special to strinterp. You shouldn't\nlet users feed into the first parameter of fmt.Sprintf, or any other such\nstring, in any language for that matter. It's possible some are \"safe\" to\ndo that in, but given the wide range of havoc done over the years by\nletting users control interpolation strings, I would just recommend against\nit unconditionally. Even when \"safe\" it probably isn't what you mean.\n\nCare should also be taken in the construction of filters. If they get much\n\"smarter\" than a for loop iterating over bytes\/runes and doing \"something\" with\nthem, you're starting to ask for trouble if user input passes through\nthem. Generally the entire point of strinterp is to handle potentially\nuntrusted input in a safe manner, so if you start \"interpreting\" user input\nyou could be creating openings for attackers.\n\nContributing\n\nI'm interested in pull requests for more Formatters and Encoders for the\n\"default Interpolator\", though ideally only for things in the standard\nlibrary.\n\n*\/\npackage strinterp\n<|endoftext|>"}

The default prefix is the package name\n\/\/ of the source package followed by an underscore. The -prefix option\n\/\/ specifies an alternate prefix.\n\/\/\n\/\/ Occasionally it is necessary to rewrite imports during the bundling\n\/\/ process. The -import option, which may be repeated, specifies that\n\/\/ an import of \"old\" should be rewritten to import \"new\" instead.\n\/\/\n\/\/ Example\n\/\/\n\/\/ Bundle archive\/zip for inclusion in cmd\/dist:\n\/\/\n\/\/\tcd $GOROOT\/src\/cmd\/dist\n\/\/\tbundle -o zip.go archive\/zip\n\/\/\n\/\/ Bundle golang.org\/x\/net\/http2 for inclusion in net\/http,\n\/\/ prefixing all identifiers by \"http2\" instead of \"http2_\",\n\/\/ and rewriting the import \"golang.org\/x\/net\/http2\/hpack\"\n\/\/ to \"internal\/golang.org\/x\/net\/http2\/hpack\":\n\/\/\n\/\/\tcd $GOROOT\/src\/net\/http\n\/\/\tbundle -o h2_bundle.go \\\n\/\/\t\t-prefix http2 \\\n\/\/\t\t-import golang.org\/x\/net\/http2\/hpack=internal\/golang.org\/x\/net\/http2\/hpack \\\n\/\/\t\tgolang.org\/x\/net\/http2\n\/\/\n\/\/ Two ways to update the http2 bundle:\n\/\/\n\/\/\tgo generate net\/http\n\/\/\n\/\/\tcd $GOROOT\/src\/net\/http\n\/\/\tgo generate\n\/\/\n\/\/ Update both bundles, restricting ``go generate'' to running bundle commands:\n\/\/\n\/\/\tgo generate -run bundle cmd\/dist net\/http\n\/\/\npackage main\n\nimport (\n\t\"bytes\"\n\t\"flag\"\n\t\"fmt\"\n\t\"go\/ast\"\n\t\"go\/build\"\n\t\"go\/format\"\n\t\"go\/parser\"\n\t\"go\/token\"\n\t\"go\/types\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"os\"\n\t\"path\"\n\t\"strings\"\n\n\t\"golang.org\/x\/tools\/go\/loader\"\n)\n\nvar (\n\toutputFile = flag.String(\"o\", \"\", \"write output to `file` (default standard output)\")\n\tdstPath    = flag.String(\"dst\", \"\", \"set destination import `path` (default taken from current directory)\")\n\tpkgName    = flag.String(\"pkg\", \"\", \"set destination package `name` (default taken from current directory)\")\n\tprefix     = flag.String(\"prefix\", \"\", \"set bundled identifier prefix to `p` (default source package name + \\\"_\\\")\")\n\n\timportMap = map[string]string{}\n)\n\nfunc init() {\n\tflag.Var(flagFunc(addImportMap), \"import\", \"rewrite import using `map`, of form old=new (can be repeated)\")\n}\n\nfunc addImportMap(s string) {\n\tif strings.Count(s, \"=\") != 1 {\n\t\tlog.Fatal(\"-import argument must be of the form old=new\")\n\t}\n\ti := strings.Index(s, \"=\")\n\told, new := s[:i], s[i+1:]\n\tif old == \"\" || new == \"\" {\n\t\tlog.Fatal(\"-import argument must be of the form old=new;

The default prefix is the package name\n\/\/ of the source package followed by an underscore. The -prefix option\n\/\/ specifies an alternate prefix.\n\/\/\n\/\/ Occasionally it is necessary to rewrite imports during the bundling\n\/\/ process. The -import option, which may be repeated, specifies that\n\/\/ an import of \"old\" should be rewritten to import \"new\" instead.\n\/\/\n\/\/ Example\n\/\/\n\/\/ Bundle archive\/zip for inclusion in cmd\/dist:\n\/\/\n\/\/\tcd $GOROOT\/src\/cmd\/dist\n\/\/\tbundle -o zip.go archive\/zip\n\/\/\n\/\/ Bundle golang.org\/x\/net\/http2 for inclusion in net\/http,\n\/\/ prefixing all identifiers by \"http2\" instead of \"http2_\",\n\/\/ and rewriting the import \"golang.org\/x\/net\/http2\/hpack\"\n\/\/ to \"internal\/golang.org\/x\/net\/http2\/hpack\":\n\/\/\n\/\/\tcd $GOROOT\/src\/net\/http\n\/\/\tbundle -o h2_bundle.go \\\n\/\/\t\t-prefix http2 \\\n\/\/\t\t-import golang.org\/x\/net\/http2\/hpack=internal\/golang.org\/x\/net\/http2\/hpack \\\n\/\/\t\tgolang.org\/x\/net\/http2\n\/\/\n\/\/ Two ways to update the http2 bundle:\n\/\/\n\/\/\tgo generate net\/http\n\/\/\n\/\/\tcd $GOROOT\/src\/net\/http\n\/\/\tgo generate\n\/\/\n\/\/ Update both bundles, restricting ``go generate'' to running bundle commands:\n\/\/\n\/\/\tgo generate -run bundle cmd\/dist net\/http\n\/\/\npackage main\n\nimport (\n\t\"bytes\"\n\t\"flag\"\n\t\"fmt\"\n\t\"go\/ast\"\n\t\"go\/build\"\n\t\"go\/format\"\n\t\"go\/parser\"\n\t\"go\/token\"\n\t\"go\/types\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"os\"\n\t\"path\"\n\t\"strings\"\n\n\t\"golang.org\/x\/tools\/go\/loader\"\n)\n\nvar (\n\toutputFile = flag.String(\"o\", \"\", \"write output to `file` (default standard output)\")\n\tdstPath    = flag.String(\"dst\", \"\", \"set destination import `path` (default taken from current directory)\")\n\tpkgName    = flag.String(\"pkg\", \"\", \"set destination package `name` (default taken from current directory)\")\n\tprefix     = flag.String(\"prefix\", \"\", \"set bundled identifier prefix to `p` (default source package name + \\\"_\\\")\")\n\n\timportMap = map[string]string{}\n)\n\nfunc init() {\n\tflag.Var(flagFunc(addImportMap), \"import\", \"rewrite import using `map`, of form old=new (can be repeated)\")\n}\n\nfunc addImportMap(s string) {\n\tif strings.Count(s, \"=\") != 1 {\n\t\tlog.Fatal(\"-import argument must be of the form old=new\")\n\t}\n\ti := strings.Index(s, \"=\")\n\told, new := s[:i], s[i+1:]\n\tif old == \"\" || new == \"\" {\n\t\tlog.Fatal(\"-import argument must be of the form old=new;

Tests\n\/\/ should be placed in smaller sub-packages for organizational purposes and\n\/\/ parallelism (tests are only run in parallel across different packages).\n\/\/ Integration tests should always begin with a call to CheckFilters to ensure\n\/\/ test filters can be applied, and each package containing integration tests\n\/\/ should call ptest.Main in a TestMain function if it uses ptest.\n\/\/\n\/\/ Running integration tests can be done with a go test call with any flags that\n\/\/ are required by the test pipelines, such as --runner or --endpoint.\n\/\/ Example:\n\/\/    go test -v .\/sdks\/go\/test\/integration\/... --runner=portable --endpoint=localhost:8099\n\/\/\n\/\/ Alternatively, tests can be executed by running the\n\/\/ run_validatesrunner_tests.sh script, which also performs much of the\n\/\/ environment setup, or by calling gradle commands in :sdks:go:test.\npackage integration\n\nimport (\n\t\"fmt\"\n\t\"math\/rand\"\n\t\"regexp\"\n\t\"strings\"\n\t\"testing\"\n\t\"time\"\n\n\t\/\/ common runner flag.\n\t\"github.com\/apache\/beam\/sdks\/v2\/go\/pkg\/beam\/options\/jobopts\"\n\t\"github.com\/apache\/beam\/sdks\/v2\/go\/pkg\/beam\/testing\/ptest\"\n)\n\n\/\/ Filters for temporarily skipping integration tests.

If there is a\nstatic validator set, you store it locally upon initialization of the client,\nand check against that every time.\n\nIf the validator set for the blockchain is dynamic, verifying block commits is\na bit more involved -- if there is a block at height H with a known (trusted)\nvalidator set V, and another block at height H' (H' > H) with validator set V'\n!= V, then we want a way to safely update it.\n\nFirst, we get the new (unconfirmed) validator set V' and verify that H' is\ninternally consistent and properly signed by this V'. Assuming it is a valid\nblock, we check that at least 2\/3 of the validators in V also signed it,\nmeaning it would also be valid under our old assumptions.  Then, we accept H'\nand V' as valid and trusted and use that to validate for heights X > H' until a\nmore recent and updated validator set is found.\n\nIf we cannot update directly from H -> H' because there was too much change to\nthe validator set, then we can look for some Hm (H < Hm < H') with a validator\nset Vm.  Then we try to update H -> Hm and then Hm -> H' in two steps.  If one\nof these steps doesn't work, then we continue bisecting, until we eventually\nhave to externally validate the validator set changes at every block.\n\nSince we never trust any server in this protocol, only the signatures\nthemselves, it doesn't matter if the seed comes from a (possibly malicious)\nnode or a (possibly malicious) user.  We can accept it or reject it based only\non our trusted validator set and cryptographic proofs. This makes it extremely\nimportant to verify that you have the proper validator set when initializing\nthe client, as that is the root of all trust.\n\nThe software currently assumes that the unbonding period is infinite in\nduration.  If the DynamicVerifier hasn't been updated in a while, you should\nmanually verify the block headers using other sources.\n\nTODO: Update the software to handle cases around the unbonding period.\n\n*\/\npackage lite\n<commit_msg>docs: fix lite client formatting (#3198)<commit_after>\/*\nPackage lite allows you to securely validate headers without a full node.\n\nThis library pulls together all the crypto and algorithms, so given a\nrelatively recent (< unbonding period) known validator set, one can get\nindisputable proof that data is in the chain (current state) or detect if the\nnode is lying to the client.\n\nTendermint RPC exposes a lot of info, but a malicious node could return any\ndata it wants to queries, or even to block headers, even making up fake\nsignatures from non-existent validators to justify it.
