The GCOV_PREFIX environment\n\t\/\/ variable adds a prefix to the hardcoded paths.\n\t\/\/ E.g. Given GCOV_PREFIX=\/tmp\/coverage, the hardcoded path \/ss\/build\/a.gcno becomes \/tmp\/coverage\/ss\/build\/a.gcno.\n\t\/\/ This is mainly intended for running the target program on a different machine where the hardcoded paths don't\n\t\/\/ make sense. It can also be used to avoid races.

Its purpose is to replace\n\/\/ aging methods of sharing files such as FTP. With the advent of services like\n\/\/ DropBox, Box, Google Drive and the like, this type of service is becoming more\n\/\/ commonplace EVH has some differentiating features that make it an especially\n\/\/ good tool for corporations and\/or home use.\n\/\/\n\/\/ EVH runs in two modes: server and client. Server hosts a web server interface for\n\/\/ uploading and downloading files. The Client is for uploading only and runs\n\/\/ in a terminal.

level=0)\n\/\/\n\/\/ This function is invoked by the import statement. It can be\n\/\/ replaced (by importing the builtins module and assigning to\n\/\/ builtins.__import__) in order to change semantics of the import\n\/\/ statement, but doing so is strongly discouraged as it is usually\n\/\/ simpler to use import hooks (see PEP 302) to attain the same goals\n\/\/ and does not cause issues with code which assumes the default\n\/\/ import implementation is in use. Direct use of __import__() is also\n\/\/ discouraged in favor of importlib.import_module().\n\/\/\n\/\/ The function imports the module name, potentially using the given\n\/\/ globals and locals to determine how to interpret the name in a\n\/\/ package context. The fromlist gives the names of objects or\n\/\/ submodules that should be imported from the module given by\n\/\/ name. The standard implementation does not use its locals argument\n\/\/ at all, and uses its globals only to determine the package context\n\/\/ of the import statement.\n\/\/\n\/\/ level specifies whether to use absolute or relative imports. 0 (the\n\/\/ default) means only perform absolute imports. Positive values for\n\/\/ level indicate the number of parent directories to search relative\n\/\/ to the directory of the module calling __import__() (see PEP 328\n\/\/ for the details).\n\/\/\n\/\/ When the name variable is of the form package.module, normally, the\n\/\/ top-level package (the name up till the first dot) is returned, not\n\/\/ the module named by name. However, when a non-empty fromlist\n\/\/ argument is given, the module named by name is returned.\n\/\/\n\/\/ For example, the statement import spam results in bytecode\n\/\/ resembling the following code:\n\/\/\n\/\/ spam = __import__('spam', globals(), locals(), [], 0)\n\/\/ The statement import spam.ham results in this call:\n\/\/\n\/\/ spam = __import__('spam.ham', globals(), locals(), [], 0)\n\/\/\n\/\/ Note how __import__() returns the toplevel module here because this\n\/\/ is the object that is bound to a name by the import statement.\n\/\/\n\/\/ On the other hand, the statement from spam.ham import eggs, sausage\n\/\/ as saus results in\n\/\/\n\/\/ _temp = __import__('spam.ham', globals(), locals(), ['eggs', 'sausage'], 0)\n\/\/ eggs = _temp.eggs\n\/\/ saus = _temp.sausage\n\/\/\n\/\/ Here, the spam.ham module is returned from __import__().

It can be\n\/\/ replaced (by importing the builtins module and assigning to\n\/\/ builtins.__import__) in order to change semantics of the import\n\/\/ statement, but doing so is strongly discouraged as it is usually\n\/\/ simpler to use import hooks (see PEP 302) to attain the same goals\n\/\/ and does not cause issues with code which assumes the default\n\/\/ import implementation is in use. Direct use of __import__() is also\n\/\/ discouraged in favor of importlib.import_module().\n\/\/\n\/\/ The function imports the module name, potentially using the given\n\/\/ globals and locals to determine how to interpret the name in a\n\/\/ package context. The fromlist gives the names of objects or\n\/\/ submodules that should be imported from the module given by\n\/\/ name. The standard implementation does not use its locals argument\n\/\/ at all, and uses its globals only to determine the package context\n\/\/ of the import statement.\n\/\/\n\/\/ level specifies whether to use absolute or relative imports. 0 (the\n\/\/ default) means only perform absolute imports. Positive values for\n\/\/ level indicate the number of parent directories to search relative\n\/\/ to the directory of the module calling __import__() (see PEP 328\n\/\/ for the details).\n\/\/\n\/\/ When the name variable is of the form package.module, normally, the\n\/\/ top-level package (the name up till the first dot) is returned, not\n\/\/ the module named by name. However, when a non-empty fromlist\n\/\/ argument is given, the module named by name is returned.\n\/\/\n\/\/ For example, the statement import spam results in bytecode\n\/\/ resembling the following code:\n\/\/\n\/\/ spam = __import__('spam', globals(), locals(), [], 0)\n\/\/ The statement import spam.ham results in this call:\n\/\/\n\/\/ spam = __import__('spam.ham', globals(), locals(), [], 0)\n\/\/\n\/\/ Note how __import__() returns the toplevel module here because this\n\/\/ is the object that is bound to a name by the import statement.\n\/\/\n\/\/ On the other hand, the statement from spam.ham import eggs, sausage\n\/\/ as saus results in\n\/\/\n\/\/ _temp = __import__('spam.ham', globals(), locals(), ['eggs', 'sausage'], 0)\n\/\/ eggs = _temp.eggs\n\/\/ saus = _temp.sausage\n\/\/\n\/\/ Here, the spam.ham module is returned from __import__().

The concrete types that implement\n\/\/ the Type interface are pointers. Since they are not canonicalized,\n\/\/ == cannot be used to check for equivalence, and thus we cannot\n\/\/ simply use a Go map.\n\/\/\n\/\/ Just as with map[K]V, a nil *Map is a valid empty map.\n\/\/\n\/\/ Not thread-safe.\n\/\/\ntype Map struct {\n\thasher Hasher \/\/ shared by many Maps\n\ttable map[uint32][]entry \/\/ maps hash to bucket; entry.key==nil means unused\n\tlength int \/\/ number of map entries\n}\n\n\/\/ entry is an entry (key\/value association) in a hash bucket.\ntype entry struct {\n\tkey types.Type\n\tvalue interface{}\n}\n\n\/\/ SetHasher sets the hasher used by Map.\n\/\/\n\/\/ All Hashers are functionally equivalent but contain internal state\n\/\/ used to cache the results of hashing previously seen types.\n\/\/\n\/\/ A single Hasher created by MakeHasher() may be shared among many\n\/\/ Maps. This is recommended if the instances have many keys in\n\/\/ common, as it will amortize the cost of hash computation.\n\/\/\n\/\/ A Hasher may grow without bound as new types are seen. Even when a\n\/\/ type is deleted from the map, the Hasher never shrinks, since other\n\/\/ types in the map may reference the deleted type indirectly.\n\/\/\n\/\/ Hashers are not thread-safe, and read-only operations such as\n\/\/ Map.Lookup require updates to the hasher, so a full Mutex lock (not a\n\/\/ read-lock) is require around all Map operations if a shared\n\/\/ hasher is accessed from

By default, this package listens for\ninterrupts (i.e., SIGINT), but when it detects that it is running under Einhorn\nit will additionally listen for SIGUSR2 as well, giving your application\nautomatic support for graceful upgrades.\n\nIt's worth mentioning explicitly that this package is a hack to shim graceful\nshutdown behavior into the net\/http package provided in Go 1.2. It was written\nby carefully reading the sequence of function calls net\/http happened to use as\nof this writing and finding enough surface area with which to add appropriate\nbehavior. There's a very good chance that this package will cease to work in\nfuture versions of Go, but with any luck the standard library will add support\nof its own by then.\n\nIf you're interested in figuring out how this package works, we suggest you read\nthe documentation for WrapConn() and net.go.\n*\/\npackage graceful\n\nimport (\n\t\"crypto\/tls\"\n\t\"net\"\n\t\"net\/http\"\n\t\"time\"\n)\n\n\/\/ Exactly like net\/http's Server.

By default, this package listens for\ninterrupts (i.e., SIGINT), but when it detects that it is running under Einhorn\nit will additionally listen for SIGUSR2 as well, giving your application\nautomatic support for graceful upgrades.\n\nIt's worth mentioning explicitly that this package is a hack to shim graceful\nshutdown behavior into the net\/http package provided in Go 1.2. It was written\nby carefully reading the sequence of function calls net\/http happened to use as\nof this writing and finding enough surface area with which to add appropriate\nbehavior. There's a very good chance that this package will cease to work in\nfuture versions of Go, but with any luck the standard library will add support\nof its own by then (https:\/\/code.google.com\/p\/go\/issues\/detail?id=4674).\n\nIf you're interested in figuring out how this package works, we suggest you read\nthe documentation for WrapConn() and net.go.\n*\/\npackage graceful\n\nimport (\n\t\"crypto\/tls\"\n\t\"net\"\n\t\"net\/http\"\n\t\"time\"\n)\n\n\/\/ Exactly like net\/http's Server.

Second, if beta contains only deletion changes, then alpha may or\n\t\/\/ may not be modified, but we should still propagate its contents to either\n\t\/\/ propagate changes or replace the deleted content.

There is one special case\n\t\/\/ that we can handle here in an automatic and intuitive (from the user\n\t\/\/ perspective) manner: if alpha is nil (i.e. it has no contents due to none\n\t\/\/ having existed or them having been deleted) and it's not the case that\n\t\/\/ both the ancestor and beta are directories (i.e. at least one of them is\n\t\/\/ nil or a non-directory type), then we can simply nil out the ancestor and\n\t\/\/ leave the contents on beta as they are.\n\t\/\/\n\t\/\/ To understand why this is the only case that we can handle, we have to\n\t\/\/ consider what happens as soon as one of these conditions is not met.\n\t\/\/\n\t\/\/ If alpha were non-nil, it would mean that there was content on alpha. It\n\t\/\/ wouldn't say anything about whether or not the content was modified (we'd\n\t\/\/ have to do a diff against the ancestor to determine that), but neither\n\t\/\/ case can work. Even if the content is not modified, we still want to\n\t\/\/ repropagate it to enforce mirroring, but we're blocked from doing that by\n\t\/\/ the changes that exist on beta. If the content is modified, then there's\n\t\/\/ an obvious conflict since we couldn't propagate the modification without\n\t\/\/ overwriting the changes on beta. Even if alpha is only subject to\n\t\/\/ deletion changes (i.e. it's a subtree of the ancestor), we still want to\n\t\/\/ maintain the mirroring property of the synchronization, and we can't\n\t\/\/ propagate the deletion without overwriting the contents on beta. You may\n\t\/\/ be asking yourself about the case of alpha and beta both being\n\t\/\/ directories, with alpha having deleted a subset of the tree that doesn't\n\t\/\/ conflict with beta's changes. Well, if both were directories, we wouldn't\n\t\/\/ be here, because we would have simply recursed. At this point, it's\n\t\/\/ guaranteed that one of alpha or beta is not a directory, in which case\n\t\/\/ there's no way that propagation of alpha's (non-nil) contents (modified\n\t\/\/ or not) won't overwrite the changes to beta.\n\t\/\/\n\t\/\/ The requirement that at least one of ancestor or beta be a (potentially\n\t\/\/ nil) non-directory entry is more subtle and partially heuristically\n\t\/\/ motivated. If both were directories, it would indicate that alpha had\n\t\/\/ also previously been a directory (remember that it can't be now or we\n\t\/\/ would have recursed) and it would not be well-defined which portion of\n\t\/\/ the deletions on alpha should be propagated to the contents of beta. You\n\t\/\/ can't just leave beta as is because that policy would prevent entire\n\t\/\/ directory hierarchies from being deleted, even if only modified partially\n\t\/\/ at a much lower level. Trying to figure out which content on beta should\n\t\/\/ be deleted to \"represent\" the deletion changes on alpha is neither\n\t\/\/ well-defined nor intuitive. Additionally, at the end of the day, there's\n\t\/\/ no way to delineate the \"source\" of creation of the directories acting as\n\t\/\/ parents to the modified content (were they \"created\" on alpha or beta?\n\t\/\/ what if it was due to both-created-same behavior? etc.).\n\t\/\/\n\t\/\/ Despite the relative complexity of this condition, it still covers a\n\t\/\/ large number of cases. For example, it covers the case that beta creates\n\t\/\/ contents - they are simply not propagated back to alpha. It also covers\n\t\/\/ the case where alpha has deleted something and beta has modified or\n\t\/\/ replaced it - the new beta contents are simply left in place (assuming\n\t\/\/ that they aren't contents at a lower level of a directory hierarchy that\n\t\/\/ alpha has deleted).\n\t\/\/\n\t\/\/ Finally, since the ancestor is\n\t\/\/ updated with Apply, the Old value will be ignored anyway (since it\n\t\/\/ doesn't need to be transitioned away like on-disk contents do during\n\t\/\/ a transition), so we just set it to nil, rather than the old contents\n\t\/\/ of the ancestor.\n\tancestorOrBetaNonDirectory := ancestor == nil ||\n\t\tancestor.Kind != EntryKind_Directory ||\n\t\tbeta == nil ||\n\t\tbeta.Kind != EntryKind_Directory\n\tif alpha == nil && ancestorOrBetaNonDirectory {\n\t\tif ancestor != nil {\n\t\t\t\/\/ As above, since the ancestor is updated with Apply, the Old value\n\t\t\t\/\/ will be ignored anyway (since it doesn't need to be transitioned\n\t\t\t\/\/ away like on-disk contents do during a transition), so we just\n\t\t\t\/\/ leave it nil, rather than set it to the old ancestor contents.\n\t\t\tr.ancestorChanges = append(r.ancestorChanges, &Change{Path: path})\n\t\t}\n\t\treturn\n\t}\n\n\t\/\/ At this point, there's nothing else we can handle using heuristics.

For beta, we still report only non-deletion\n\t\/\/ changes, because those are the only changes from which conflict can arise\n\t\/\/ in the unidirectional case. We also don't necessarily know here that\n\t\/\/ alpha is modified - it may not be. In that case, the conflict arises\n\t\/\/ implicitly from the need to mirror alpha's (unchanged) contents to beta,\n\t\/\/ and we still need to ensure that the recorded conflict indicates changes\n\t\/\/ on both endpoints, even if the change on alpha is \"synthetic\" and\n\t\/\/ represents a change from itself to itself.

First, if beta is unmodified,\n\t\/\/ then we know that alpha must be modified, and thus we can propagate over\n\t\/\/ beta. Second, if beta contains only deletion changes, then alpha may or\n\t\/\/ may not be modified, but we should still propagate its contents to either\n\t\/\/ propagate changes or replace the deleted content. Fortunately, both of\n\t\/\/ these cases can be handled with a single check.\n\tbetaDeltaNonDeletion := nonDeletionChangesOnly(diff(path, ancestor, beta))\n\tif len(betaDeltaNonDeletion) == 0 {\n\t\tr.betaChanges = append(r.betaChanges, &Change{\n\t\t\tPath: path,\n\t\t\tOld: beta,\n\t\t\tNew: alpha,\n\t\t})\n\t\treturn\n\t}\n\n\t\/\/ At this point, we know that beta is modified and contains non-deletion\n\t\/\/ changes (either modifications or creations). There is one special case\n\t\/\/ that we can handle here in an automatic and intuitive (from the user\n\t\/\/ perspective) manner: if alpha is nil (i.e. it has no contents due to none\n\t\/\/ having existed or them having been deleted) and it's not the case that\n\t\/\/ both the ancestor and beta are directories (i.e. at least one of them is\n\t\/\/ nil or a non-directory type), then we can simply nil out the ancestor and\n\t\/\/ leave the contents on beta as they are.\n\t\/\/\n\t\/\/ To understand why this is the only case that we can handle, we have to\n\t\/\/ consider what happens as soon as one of these conditions is not met.\n\t\/\/\n\t\/\/ If alpha were non-nil, it would mean that there was content on alpha. It\n\t\/\/ wouldn't say anything about whether or not the content was modified (we'd\n\t\/\/ have to do a diff against the ancestor to determine that), but neither\n\t\/\/ case can work. Even if the content is not modified, we still want to\n\t\/\/ repropagate it to enforce mirroring, but we're blocked from doing that by\n\t\/\/ the changes that exist on beta. If the content is modified, then there's\n\t\/\/ an obvious conflict since we couldn't propagate the modification without\n\t\/\/ overwriting the changes on beta. Even if alpha is only subject to\n\t\/\/ deletion changes (i.e. it's a subtree of the ancestor), we still want to\n\t\/\/ maintain the mirroring property of the synchronization, and we can't\n\t\/\/ propagate the deletion without overwriting the contents on beta. You may\n\t\/\/ be asking yourself about the case of alpha and beta both being\n\t\/\/ directories, with alpha having deleted a subset of the tree that doesn't\n\t\/\/ conflict with beta's changes. Well, if both were directories, we wouldn't\n\t\/\/ be here, because we would have simply recursed. At this point, it's\n\t\/\/ guaranteed that one of alpha or beta is not a directory, in which case\n\t\/\/ there's no way that propagation of alpha's (non-nil) contents (modified\n\t\/\/ or not) won't overwrite the changes to beta.\n\t\/\/\n\t\/\/ The requirement that at least one of ancestor or beta be a (potentially\n\t\/\/ nil) non-directory entry is more subtle and partially heuristically\n\t\/\/ motivated. If both were directories, it would indicate that alpha had\n\t\/\/ also previously been a directory (remember that it can't be now or we\n\t\/\/ would have recursed) and it would not be well-defined which portion of\n\t\/\/ the deletions on alpha should be propagated to the contents of beta. You\n\t\/\/ can't just leave beta as is because that policy would prevent entire\n\t\/\/ directory hierarchies from being deleted, even if only modified partially\n\t\/\/ at a much lower level. Trying to figure out which content on beta should\n\t\/\/ be deleted to \"represent\" the deletion changes on alpha is neither\n\t\/\/ well-defined nor intuitive. Additionally, at the end of the day, there's\n\t\/\/ no way to delineate the \"source\" of creation of the directories acting as\n\t\/\/ parents to the modified content (were they \"created\" on alpha or beta?\n\t\/\/ what if it was due to both-created-same behavior? etc.).\n\t\/\/\n\t\/\/ Despite the relative complexity of this condition, it still covers a\n\t\/\/ large number of cases. For example, it covers the case that beta creates\n\t\/\/ contents - they are simply not propagated back to alpha. It also covers\n\t\/\/ the case where alpha has deleted something and beta has modified or\n\t\/\/ replaced it - the new beta contents are simply left in place (assuming\n\t\/\/ that they aren't contents at a lower level of a directory hierarchy that\n\t\/\/ alpha has deleted).\n\t\/\/\n\t\/\/ Finally, since the ancestor is updated with Apply, the Old value will be\n\t\/\/ ignored anyway (since it doesn't need to be transitioned away like\n\t\/\/ on-disk contents do during a transition), so we just set it to nil,\n\t\/\/ rather than the old contents of the ancestor.\n\tancestorOrBetaNonDirectory := ancestor == nil ||\n\t\tancestor.Kind != EntryKind_Directory ||\n\t\tbeta == nil ||\n\t\tbeta.Kind != EntryKind_Directory\n\tif alpha == nil && ancestorOrBetaNonDirectory {\n\t\tif ancestor != nil {\n\t\t\t\/\/ As above, since the ancestor is updated with Apply, the Old value\n\t\t\t\/\/ will be ignored anyway (since it doesn't need to be transitioned\n\t\t\t\/\/ away like on-disk contents do during a transition), so we just\n\t\t\t\/\/ leave it nil, rather than set it to the old ancestor contents.\n\t\t\tr.ancestorChanges = append(r.ancestorChanges, &Change{Path: path})\n\t\t}\n\t\treturn\n\t}\n\n\t\/\/ At this point, there's nothing else we can handle using heuristics. We\n\t\/\/ simply have to mark a conflict. Worth noting is that, for alpha, we\n\t\/\/ report all changes, not just non-deletion changes, because even pure\n\t\/\/ deletion changes on alpha's part can be the source of a conflict (unlike\n\t\/\/ in the bidirectional case). For beta, we still report only non-deletion\n\t\/\/ changes, because those are the only changes from which conflict can arise\n\t\/\/ in the unidirectional case. We also don't necessarily know here that\n\t\/\/ alpha is modified - it may not be. In that case, the conflict arises\n\t\/\/ implicitly from the need to mirror alpha's (unchanged) contents to beta,\n\t\/\/ and we still need to ensure that the recorded conflict indicates changes\n\t\/\/ on both endpoints, even if the change on alpha is \"synthetic\" and\n\t\/\/ represents a change from itself to itself.

Your\n\/\/ endpoint JSON should look something like this:\n\/\/\n\/\/ {\n\/\/ \"pg_user\":\"username-for-postgres\",\n\/\/ \"pg_password\":\"password-for-above-user\",\n\/\/ \"pg_host\":\"hostname-or-ip-of-pg-server\",\n\/\/ \"pg_port\":\"port-above-pg-server-listens-on\", # optional\n\/\/ \"pg_database\": \"name-of-db-to-backup\", # optional\n\/\/ \"pg_bindir\": \"PostgreSQL binaries directory\" # optional\n\/\/ }\n\/\/\n\/\/ The `pg_port` field is optional. If specified, the plugin will connect to the\n\/\/ given port to perform backups. If not specified plugin will connect to\n\/\/ default postgres port 5432.\n\/\/\n\/\/ The `pg_database` field is optional. If specified, the plugin will only\n\/\/ perform backups of the named database. If not specified (the default), all\n\/\/ databases will be backed up.\n\/\/\n\/\/ The `pg_bindir` field is optional. It specifies where to find the PostgreSQL\n\/\/ binaries such as pg_dump \/ pg_dumpall \/ pg_restore. If specified, the plugin\n\/\/ will attempt to use binaries from within the given directory. If not specified\n\/\/ the plugin will default to trying to use binaries in\n\/\/ '\/var\/vcap\/packages\/postgres\/bin'.\n\/\/\n\/\/ BACKUP DETAILS\n\/\/\n\/\/ The `postgres` plugin makes use of `pg_dumpall -c` to back up all databases\n\/\/ on the postgres server it connects to. There is currently no filtering of\n\/\/ individual databases to back up, unless that is done via the postgres users\n\/\/ and roles. The dumps generated include SQL to clean up existing databses\/tables,\n\/\/ so that the restore will go smoothly.\n\/\/\n\/\/ Backing up with the `postgres` plugin will not drop any existing connections to the\n\/\/ database, or restart the service.\n\/\/\n\/\/ RESTORE DETAILS\n\/\/\n\/\/ To restore, the `postgres` plugin connects to the postgres server using the `psql`\n\/\/ command. It then feeds in the backup data (`pg_dumpall` output). To work around\n\/\/ cases where the databases being restored cannot be recreated due to existing connections,\n\/\/ the plugin disallows incoming connections for each database, and disconnects the existing\n\/\/ connections, prior to dropping the database. Once the database is recreated, connections\n\/\/ are once again allowed into the database.\n\/\/\n\/\/ Restoring with the `postgres` plugin will terminate existing connections to the database,\n\/\/ but does not need to restart the postgres service.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ This plugin relies on the `pg_dumpall` and `psql` commands. Please ensure that they\n\/\/ are present on the system that will be running the backups + restores for postgres.\n\/\/ If you are using shield-boshrelease to deploy SHIELD, these tools are provided,

Only one type of the arguments may be specified: filenames,\n\t\tresources and names, or resources and label selector.\n\n\t\tSome resources, such as pods, support graceful deletion. These resources define a default period\n\t\tbefore they are forcibly terminated (the grace period) but you may override that value with\n\t\tthe --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often\n\t\trepresent entities in the cluster, deletion may not be acknowledged immediately. If the node\n\t\thosting a pod is down or cannot reach the API server, termination may take significantly longer\n\t\tthan the grace period. To force delete a resource, you must pass a grace period of 0 and specify\n\t\tthe --force flag.\n\t\tNote: only a subset of resources support graceful deletion. In absence of the support, --grace-period is ignored.\n\n\t\tIMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been\n\t\tterminated, which can leave those processes running until the node detects the deletion and\n\t\tcompletes graceful deletion. If your processes use shared storage or talk to a remote API and\n\t\tdepend on the name of the pod to identify themselves, force deleting those pods may result in\n\t\tmultiple processes running on different machines using the same identification which may lead\n\t\tto data corruption or inconsistency. Only force delete pods when you are sure the pod is\n\t\tterminated, or if your application can tolerate multiple copies of the same pod running at once.\n\t\tAlso, if you force delete pods the scheduler may place new pods on those nodes before the node\n\t\thas released those resources and causing those pods to be evicted immediately.\n\n\t\tNote that the delete command does NOT do resource version checks, so if someone submits an\n\t\tupdate to a resource right when you submit a delete, their update will be lost along with the\n\t\trest of the resource.`))\n\n\tdeleteExample = templates.Examples(i18n.T(`\n\t\t# Delete a pod using the type and name specified in pod.json.\n\t\tkubectl delete -f .\/pod.json\n\n\t\t# Delete resources from a directory containing kustomization.yaml - e.g. dir\/kustomization.yaml.\n\t\tkubectl delete -k dir\n\n\t\t# Delete a pod based on the type and name in the JSON passed into stdin.\n\t\tcat pod.json | kubectl delete -f -\n\n\t\t# Delete pods and services with same names \"baz\" and \"foo\"\n\t\tkubectl delete pod,service baz foo\n\n\t\t# Delete pods and services with label name=myLabel.\n\t\tkubectl delete pods,services -l name=myLabel\n\n\t\t# Delete a pod with minimal delay\n\t\tkubectl delete pod foo --now\n\n\t\t# Force delete a pod on a dead node\n\t\tkubectl delete pod foo --grace-period=0 --force\n\n\t\t# Delete all pods\n\t\tkubectl delete pods --all`))\n)\n\ntype DeleteOptions struct {\n\tresource.FilenameOptions\n\n\tLabelSelector string\n\tFieldSelector string\n\tDeleteAll bool\n\tDeleteAllNamespaces bool\n\tIgnoreNotFound bool\n\tCascade bool\n\tDeleteNow bool\n\tForceDeletion bool\n\tWaitForDeletion bool\n\tQuiet bool\n\tWarnClusterScope bool\n\tRaw string\n\n\tGracePeriod int\n\tTimeout time.Duration\n\n\tOutput string\n\n\tDynamicClient dynamic.Interface\n\tMapper meta.RESTMapper\n\tResult *resource.Result\n\n\tgenericclioptions.IOStreams\n}\n\nfunc NewCmdDelete(f cmdutil.Factory, streams genericclioptions.IOStreams) *cobra.Command {\n\tdeleteFlags := NewDeleteCommandFlags(\"containing the resource to delete.\")\n\n\tcmd := &cobra.Command{\n\t\tUse: \"delete ([-f FILENAME] | [-k DIRECTORY] | TYPE [(NAME | -l label | --all)])\",\n\t\tDisableFlagsInUseLine: true,\n\t\tShort: i18n.T(\"Delete resources by filenames, stdin, resources and names, or by resources and label selector\"),\n\t\tLong: deleteLong,\n\t\tExample: deleteExample,\n\t\tRun: func(cmd *cobra.Command, args []string) {\n\t\t\to := deleteFlags.ToOptions(nil, streams)\n\t\t\tcmdutil.CheckErr(o.Complete(f, args, cmd))\n\t\t\tcmdutil.CheckErr(o.Validate())\n\t\t\tcmdutil.CheckErr(o.RunDelete(f))\n\t\t},\n\t\tSuggestFor: []string{\"rm\"},\n\t}\n\n\tdeleteFlags.AddFlags(cmd)\n\n\treturn cmd\n}\n\nfunc (o *DeleteOptions) Complete(f cmdutil.Factory, args []string, cmd *cobra.Command) error {\n\tcmdNamespace, enforceNamespace, err := f.ToRawKubeConfigLoader().Namespace()\n\tif err != nil {\n\t\treturn err\n\t}\n\n\to.WarnClusterScope = enforceNamespace && !o.DeleteAllNamespaces\n\n\tif o.DeleteAll || len(o.LabelSelector) > 0 || len(o.FieldSelector) > 0 {\n\t\tif f := cmd.Flags().Lookup(\"ignore-not-found\"); f != nil && !f.Changed {\n\t\t\t\/\/ If the user didn't explicitly set the option, default to ignoring NotFound errors when used with --all, -l, or --field-selector\n\t\t\to.IgnoreNotFound = true\n\t\t}\n\t}\n\tif o.DeleteNow {\n\t\tif o.GracePeriod != -1 {\n\t\t\treturn fmt.Errorf(\"--now and --grace-period cannot be specified together\")\n\t\t}\n\t\to.GracePeriod = 1\n\t}\n\tif o.GracePeriod == 0 && !o.ForceDeletion {\n\t\t\/\/ To preserve backwards compatibility, but prevent accidental data loss, we convert --grace-period=0\n\t\t\/\/ into --grace-period=1.

This last bit captures the fact that if they're\n\t\/\/all in the same row (but different columns) that's still quite good.\n\t\/\/Then, we normalize the result based on the highest and lowest possible scores.\n\n\tselfRow := make([]float64, DIM)\n\tselfCol := make([]float64, DIM)\n\tselfBlock := make([]float64, DIM)\n\n\totherRow := make([]float64, DIM)\n\totherCol := make([]float64, DIM)\n\totherBlock := make([]float64, DIM)\n\n\t\/\/How much to add each time we find a cell with that row\/col\/block.\n\t\/\/This saves us from having to loop through again to compute the average\n\tselfProportion := float64(1) \/ float64(len(self))\n\totherProportion := float64(1) \/ float64(len(other))\n\n\tfor _, cell := range self {\n\t\tselfRow[cell.Row] += selfProportion\n\t\tselfCol[cell.Col] += selfProportion\n\t\tselfBlock[cell.Block] += selfProportion\n\t}\n\n\tfor _, cell := range other {\n\t\totherRow[cell.Row] += otherProportion\n\t\totherCol[cell.Col] += otherProportion\n\t\totherBlock[cell.Block] += otherProportion\n\t}\n\n\trowDiff := 0.0\n\tcolDiff := 0.0\n\tblockDiff := 0.0\n\n\t\/\/Now, compute the diffs.\n\tfor i := 0; i < DIM; i++ {\n\t\trowDiff += math.Abs(selfRow[i] - otherRow[i])\n\t\tcolDiff += math.Abs(selfCol[i] - otherCol[i])\n\t\tblockDiff += math.Abs(selfBlock[i] - otherBlock[i])\n\t}\n\n\t\/\/Now sort the diffs; we care disproportionately about the one that matches best.\n\tdiffs := []float64{rowDiff, colDiff, blockDiff}\n\tsort.Float64s(diffs)\n\n\t\/\/We care about the lowest diff the most (capturing the notion that if they line up in row but nothing else, that's still quite good!)\n\tweights := []int{4, 2, 1}\n\n\tresult := 0.0\n\n\tfor i := 0; i < 3; i++ {\n\t\tfor j := 0; j < weights[i]; j++ {\n\t\t\tresult += diffs[i]\n\t\t}\n\t}\n\n\t\/\/Divide by 4 + 2 + 1 = 7\n\tresult \/= 7.0\n\n\treturn result\n\n}\n\nfunc (self CellList) Description() string {\n\tstrings := make(stringSlice, len(self))\n\n\tfor i, cell := range self {\n\t\tstrings[i] = cell.ref().String()\n\t}\n\n\treturn strings.description()\n}\n\nfunc (self CellList) sameAsRefs(refs []cellRef) bool {\n\tcellSet := make(map[string]bool)\n\tfor _, cell := range self {\n\t\tcellSet[cell.ref().String()] = true\n\t}\n\n\trefSet := make(map[string]bool)\n\tfor _, ref := range refs {\n\t\trefSet[ref.String()] = true\n\t}\n\n\tif len(cellSet) != len(refSet) {\n\t\treturn false\n\t}\n\n\tfor item, _ := range cellSet {\n\t\tif _, ok := refSet[item]; !ok {\n\t\t\treturn false\n\t\t}\n\t}\n\n\treturn true\n}\n\nfunc (self cellRef) Cell(grid *Grid) *Cell {\n\tif grid == nil {\n\t\treturn nil\n\t}\n\treturn grid.Cell(self.row, self.col)\n}\n\nfunc (self cellRef) String() string {\n\treturn \"(\" + strconv.Itoa(self.row) + \",\" + strconv.Itoa(self.col) + \")\"\n}\n\nfunc (self stringSlice) description() string {\n\tif len(self) == 0 {\n\t\treturn \"\"\n\t}\n\n\tif len(self) == 1 {\n\t\treturn self[0]\n\t}\n\n\tif len(self) == 2 {\n\t\treturn self[0] + \" and \" + self[1]\n\t}\n\n\tresult := strings.Join(self[:len(self)-1], \", \")\n\n\treturn result + \", and \" + self[len(self)-1]\n}\n\nfunc (self IntSlice) Description() string {\n\n\tstrings := make(stringSlice, len(self))\n\n\tfor i, num := range self {\n\t\tstrings[i] = strconv.Itoa(num)\n\t}\n\n\treturn strings.description()\n\n}\n\n\/\/returns an IntSlice like self, but with any dupes removed.\nfunc (self IntSlice) Unique() IntSlice {\n\t\/\/TODO: test this.\n\treturn self.toIntSet().toSlice()\n}\n\nfunc (self IntSlice) Same() bool {\n\tif len(self) == 0 {\n\t\treturn true\n\t}\n\ttarget := self[0]\n\tfor _, num := range self {\n\t\tif target != num {\n\t\t\treturn false\n\t\t}\n\t}\n\treturn true\n}\n\nfunc (self IntSlice) SameContentAs(otherSlice IntSlice) bool {\n\t\/\/Same as SameAs, but doesn't care about order.\n\n\t\/\/TODO: impelement this using intSets.

HISTORY\n======== =======\n19 Jul 22 -- First version. I'm writing this as I go along, pulling code from other pgms as I need them.\n I want this to take an input string on the command line. This string will be a regexp used to match against a filename, like what rex.go does.\n From the resultant slice of matches of this regexp, I'll shuffle it and then feed them one at a time into vlc.\n So it looks like I'll need pieces of rex.go, shuffle code from bj.go, and then launching and external pgm code like I do in a few places now.\n The final launching loop will pause and exit if I want it to, like I did w\/ the pid and windows title matching routines. I'll let the import list auto-populate.\n20 Jul 22 -- Added verboseFlag being set will have it output the filename w\/ each loop iteration. And I added 'x' to the exit key behavior.\n21 Jul 22 -- Now called lauv, it will output n files on the command line to vlc. This way I can use 'n' from within vlc.\n22 Jul 22 -- I can't get this to work by putting several filenames on the command line and it reading them all in. Maybe I'll try redirection.\n23 Jul 22 -- I finally figured out how to work w\/ variadic params, after searching online. An answer in stack overflow helped me a lot.

Conceptually, a Caret and a Frame's text is like an\n\/\/ int c and a []byte t such that the text before and after that Caret is t[:c]\n\/\/ and t[c:]. That byte-count location remains unchanged even when a Frame is\n\/\/ re-sized and laid out into a new tree of Paragraphs, Lines and Boxes.\n\/\/\n\/\/ A Frame can have multiple open Carets. For example, the beginning and end of\n\/\/ a text selection can be represented by two Carets. Multiple Carets for the\n\/\/ one Frame are not safe to use concurrently, but it is valid to interleave\n\/\/ such operations sequentially. For example, if two Carets c0 and c1 for the\n\/\/ one Frame are positioned at the 10th and 20th byte, and 4 bytes are written\n\/\/ to c0, inserting what becomes the equivalent of text[10:14], then c0's\n\/\/ position is updated to be 14 but c1's position is also updated to be 24.\ntype Caret struct {\n\tf *Frame\n\n\t\/\/ caretsIndex is the index of this Caret in the f.carets slice.\n\tcaretsIndex int\n\n\t\/\/ p, l and b index the Caret's Paragraph, Line and Box. None of these\n\t\/\/ values can be zero.\n\tp, l, b int32\n\n\t\/\/ pos is the Caret's position in the text, in layout order. It is the \"c\"\n\t\/\/ as in \"t[:c]\" in the doc comment for type Caret above.

Conceptually, a Caret and a Frame's text is like an\n\/\/ int c and a []byte t such that the text before and after that Caret is t[:c]\n\/\/ and t[c:]. That byte-count location remains unchanged even when a Frame is\n\/\/ re-sized and laid out into a new tree of Paragraphs, Lines and Boxes.\n\/\/\n\/\/ A Frame can have multiple open Carets. For example, the beginning and end of\n\/\/ a text selection can be represented by two Carets. Multiple Carets for the\n\/\/ one Frame are not safe to use concurrently, but it is valid to interleave\n\/\/ such operations sequentially. For example, if two Carets c0 and c1 for the\n\/\/ one Frame are positioned at the 10th and 20th byte, and 4 bytes are written\n\/\/ to c0, inserting what becomes the equivalent of text[10:14], then c0's\n\/\/ position is updated to be 14 but c1's position is also updated to be 24.\ntype Caret struct {\n\tf *Frame\n\n\t\/\/ caretsIndex is the index of this Caret in the f.carets slice.\n\tcaretsIndex int\n\n\t\/\/ p, l and b index the Caret's Paragraph, Line and Box.

It matches the URL of each incoming\n\/\/ request against a list of registered patterns and calls the handler for\n\/\/ the pattern that most closely matches the URL.\n\/\/\n\/\/ Patterns name are fixed, rooted paths, like \"\/favicon.ico\", or rooted\n\/\/ subtrees like \"\/images\/\" (note the trailing slash). Longer patterns take\n\/\/ precedence over shorter ones, so that if there are handlers registered for\n\/\/ both \"\/images\/\" and \"\/images\/thumbnails\/\", the latter handler will be called\n\/\/ for paths beginning \"\/images\/thumbnails\/\" and the former will receive\n\/\/ requests for any other paths in the \"\/images\/\" subtree.\n\/\/\n\/\/ Note that since a pattern ending in a slash names a rooted subtree, the\n\/\/ pattern \"\/\" matches all paths not matched by other registered patterns,\n\/\/ not just the URL with Path == \"\/\".\n\/\/\n\/\/ If a subtree has been registered and a request is received naming the subtree root without its trailing slash, ServeMux redirects that request to\n\/\/ the subtree root (adding the trailing slash). This behavior can be overridden\n\/\/ with a separate registration for the path without the trailing slash. For\n\/\/ example, registering \"\/images\/\" causes ServeMux to redirect a request for\n\/\/ \"\/images\" to \"\/images\/\", unless \"\/images\" has been registered separately.\n\/\/\n\/\/ Patterns may optionally begin with a host name, restricting matches to URLs\n\/\/ on that host only. Host-specific patterns take precedence over general\n\/\/ patterns, so that a handler might register for the two patterns \"\/codesearch\"\n\/\/ and \"codesearch.google.com\/\" without also taking over requests for\n\/\/ \"http:\/\/www.google.com\/\".\n\/\/\n\/\/ ServeMux also takes care of sanitizing the URL request path and the Host\n\/\/ header, stripping the port number and redirecting any request containing . or\n\/\/ .. elements or repeated slashes to an equivalent, cleaner URL.\n\/\/\n\/\/ Multiple HTTP methods can be served for one pattern and the user is expected\n\/\/ to register a handler for each method supported. These will be combined\n\/\/ into one handler per pattern. The framework will then match each\n\/\/ incoming request to its underlying handler according to its HTTP method.\ntype ServeMux struct {\n\tmux *http.ServeMux\n\tdomains map[string]bool\n\tdisp Dispatcher\n\n\t\/\/ Maps user-provided patterns to combined handlers which encapsulate\n\t\/\/ multiple handlers, each one associated with an HTTP method.\n\thandlers map[string]methodHandler\n}\n\n\/\/ NewServeMux allocates and returns a new ServeMux\n\/\/ TODO(@mattiasgrenfeldt, @mihalimara22): make domains a variadic of string ..\/\/**literals**.\nfunc NewServeMux(dispatcher Dispatcher, domains ...string) *ServeMux {\n\td := map[string]bool{}\n\tfor _, host := range domains {\n\t\td[host] = true\n\t}\n\treturn &ServeMux{\n\t\tmux: http.NewServeMux(),\n\t\tdomains: d,\n\t\tdisp: dispatcher,\n\t\thandlers: map[string]methodHandler{},\n\t}\n}\n\n\/\/ Handle registers a handler for the given pattern and method.

It will serve either gzip or\n\/\/ identity content codings (or return 406 Not Acceptable status if\n\/\/ can do neither).\n\/\/\n\/\/ It works correctly with handlers such as http.FileServer which\n\/\/ honour Range requests by removing the Range header when requests\n\/\/ prefer gzip encoding. This is necessary since Range applies to the\n\/\/ Gzipped content and the wrapped handler is not aware of the\n\/\/ compression when it writes byte ranges.\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"compress\/gzip\"\n\t\"errors\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n)\n\n\/\/ ErrStatusNotAcceptable is returned by Write calls to the\n\/\/ http.ResponseWriter within the wrapped http.Handler if a\n\/\/ http.StatusNotAcceptable has been written by the outer Handler.\nvar ErrStatusNotAcceptable = errors.New(\"httpgzip: http.StatusNotAcceptable has been written\")\n\n\/\/ DefaultContentTypes is the default set of content types with which\n\/\/ a Handler applies Gzip compression.

If the\n\/\/ content to be written is of a type contained in its contentTypes\n\/\/ field and the request allows and prefers Gzip compression then the\n\/\/ response is compressed and the Content-Encoding header is\n\/\/ set. Otherwise a gzipResponseWriter behaves mostly like a normal\n\/\/ http.ResponseWriter.

It will serve either gzip or\n\/\/ identity content codings (or return 406 Not Acceptable status if\n\/\/ can do neither).\n\/\/\n\/\/ It works correctly with handlers such as http.FileServer which\n\/\/ honour Range requests by removing the Range header when requests\n\/\/ prefer gzip encoding. This is necessary since Range applies to the\n\/\/ Gzipped content and the wrapped handler is not aware of the\n\/\/ compression when it writes byte ranges.\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"compress\/gzip\"\n\t\"errors\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n)\n\n\/\/ ErrStatusNotAcceptable is returned by Write calls to the\n\/\/ http.ResponseWriter within the wrapped http.Handler if a\n\/\/ http.StatusNotAcceptable has been written by the outer Handler.\nvar ErrStatusNotAcceptable = errors.New(\"httpgzip: http.StatusNotAcceptable has been written\")\n\n\/\/ DefaultContentTypes is the default set of content types with which\n\/\/ a Handler applies Gzip compression. This set originates from the\n\/\/ file compression.conf within the Apache configuration found at\n\/\/ https:\/\/html5boilerplate.com\/.\nvar DefaultContentTypes = map[string]struct{}{\n\t\"application\/atom+xml\": struct{}{},\n\t\"application\/javascript\": struct{}{},\n\t\"application\/json\": struct{}{},\n\t\"application\/ld+json\": struct{}{},\n\t\"application\/manifest+json\": struct{}{},\n\t\"application\/rdf+xml\": struct{}{},\n\t\"application\/rss+xml\": struct{}{},\n\t\"application\/schema+json\": struct{}{},\n\t\"application\/vnd.geo+json\": struct{}{},\n\t\"application\/vnd.ms-fontobject\": struct{}{},\n\t\"application\/x-font-ttf\": struct{}{},\n\t\"application\/x-javascript\": struct{}{},\n\t\"application\/x-web-app-manifest+json\": struct{}{},\n\t\"application\/xhtml+xml\": struct{}{},\n\t\"application\/xml\": struct{}{},\n\t\"font\/eot\": struct{}{},\n\t\"font\/opentype\": struct{}{},\n\t\"image\/bmp\": struct{}{},\n\t\"image\/svg+xml\": struct{}{},\n\t\"image\/vnd.microsoft.icon\": struct{}{},\n\t\"image\/x-icon\": struct{}{},\n\t\"text\/cache-manifest\": struct{}{},\n\t\"text\/css\": struct{}{},\n\t\"text\/html\": struct{}{},\n\t\"text\/javascript\": struct{}{},\n\t\"text\/plain\": struct{}{},\n\t\"text\/vcard\": struct{}{},\n\t\"text\/vnd.rim.location.xloc\": struct{}{},\n\t\"text\/vtt\": struct{}{},\n\t\"text\/x-component\": struct{}{},\n\t\"text\/x-cross-domain-policy\": struct{}{},\n\t\"text\/xml\": struct{}{},\n}\n\nvar gzipWriterPool = sync.Pool{\n\tNew: func() interface{} { return gzip.NewWriter(nil) },\n}\n\nvar gzipBufPool = sync.Pool{\n\tNew: func() interface{} { return new(bytes.Buffer) },\n}\n\n\/\/ A gzipResponseWriter is a modified http.ResponseWriter. If the\n\/\/ content to be written is of a type contained in its contentTypes\n\/\/ field and the request allows and prefers Gzip compression then the\n\/\/ response is compressed and the Content-Encoding header is\n\/\/ set. Otherwise a gzipResponseWriter behaves mostly like a normal\n\/\/ http.ResponseWriter. It is important to call the Close method when\n\/\/ writing is finished in order to flush and close the Writer.\ntype gzipResponseWriter struct {\n\thttp.ResponseWriter\n\thttpStatus int\n\tcontentTypes map[string]struct{}\n\tencs []encoding\n\tgw *gzip.Writer\n\tbuf *bytes.Buffer\n}\n\nfunc newGzipResponseWriter(w http.ResponseWriter, contentTypes map[string]struct{}, encs []encoding) *gzipResponseWriter {\n\tbuf := gzipBufPool.Get().(*bytes.Buffer)\n\tbuf.Reset()\n\treturn &gzipResponseWriter{\n\t\tResponseWriter: w,\n\t\thttpStatus: http.StatusOK,\n\t\tcontentTypes: contentTypes,\n\t\tencs: encs,\n\t\tbuf: buf}\n}\n\n\/\/ init gets called by Write once at least 512 bytes have been written\n\/\/ to the temporary buffer buf, or by Close if it has not yet been\n\/\/ called. Firstly it determines the content type, either from the\n\/\/ Content-Type header, or by calling http.DetectContentType on\n\/\/ buf. Then, if needed, a gzip.Writer is initialized.

A\n\/\/ directory is uniquely identified by an object name prefix that ends with a\n\/\/ '\/', or the empty string for the root directory. Given such a prefix P, the\n\/\/ contents of directory P are:\n\/\/\n\/\/ * The \"files\" within the directory: all objects named N such that\n\/\/ * P is a strict prefix of N.\n\/\/ * The portion of N following the prefix P contains no slashes.\n\/\/\n\/\/ * The immediate \"sub-directories\": all strings P' such that\n\/\/ * P' is a legal directory prefix according to the definition above.\n\/\/ * P is a strict prefix of P'.\n\/\/ * The portion of P' following the prefix P contains exactly one slash.\n\/\/ * There is at least one objcet with name N such that N has P' as a\n\/\/ prefix.\n\/\/\n\/\/ So for example, imagine a bucket contains the following objects:\n\/\/\n\/\/ * burrito\/\n\/\/ * enchilada\/\n\/\/ * enchilada\/0\n\/\/ * enchilada\/1\n\/\/ * queso\/carne\/carnitas\n\/\/ * queso\/carne\/nachos\/\n\/\/ * taco\n\/\/\n\/\/ Then the directory structure looks like the following, where a trailing\n\/\/ slash indicates a directory and the top level is the contents of the root\n\/\/ directory:\n\/\/\n\/\/ burrito\/\n\/\/ enchilada\/\n\/\/ 0\n\/\/ 1\n\/\/ queso\/\n\/\/ carne\/\n\/\/ carnitas\n\/\/ nachos\/\n\/\/ taco\n\/\/\n\/\/ In particular, note that some directories are explicitly defined by a\n\/\/ placeholder object, whether empty (burrito\/, queso\/carne\/nachos\/) or\n\/\/ non-empty (enchilada\/), and others are implicitly defined by\n\/\/ their children (queso\/carne\/).\n\/\/\n\/\/ Not safe for concurrent access.

mission.\n\/\/\n\/\/ When beta gets back if alpha is home, alpha\n\/\/ is forced to go himself\n\/\/ on a data retrieval mission.\n\/\/\n\/\/ If they both find themselves at home at once, then the\n\/\/ tie is arbitrarily broken and alpha goes (hence\n\/\/ the name).\n\/\/\n\/\/ In this way we implement the ping-pong of\n\/\/ long-polling. Within the constraints of only\n\/\/ having two http connections open, each party\n\/\/ can send whenever they so desire, with as low\n\/\/ latency as we can muster within the constraints\n\/\/ of only using two http connections and the given\n\/\/ traffic profile of pauses on either end.\n\/\/\n\/\/ Similar to: BOSH, Comet.\n\/\/\nfunc (s *Chaser) StartAlpha() {\n\tgo func() {\n\t\tdefer

Given K=3, the following equations might be generated:\n\/\/\n\/\/ f1(x) = 78x^2 + 19x + 42\n\/\/ f2(x) = 128x^2 + 171x + 42\n\/\/ etc.\n\/\/\n\/\/ These polynomials are then evaluated for values of X > 0:\n\/\/\n\/\/ f1(1) = 139\n\/\/ f2(2) = 896\n\/\/ etc.\n\/\/\n\/\/ These (x, y) pairs are the shares given to the parties.

There's no need to hold the client mutex when calling encode, since encode itself uses a mutex to make the writes atomic. However, we need to keep the messages ordered, so add a mutex for that purpose alone. Fixes issue 1244.<commit_after>\/\/ Copyright 2010 The Go Authors.

SHIELD is intended to be a generic\n\/\/ backup\/restore plugin for a postgres server. It can be used against\n\/\/ any postgres server compatible with the `psql` and `pg_dumpall` tools\n\/\/ installed on the system where this plugin is run.\n\/\/\n\/\/ PLUGIN FEATURES\n\/\/\n\/\/ This plugin implements functionality suitable for use with the following\n\/\/ SHIELD Job components:\n\/\/\n\/\/ Target: yes\n\/\/ Store: no\n\/\/\n\/\/ PLUGIN CONFIGURATION\n\/\/\n\/\/ The endpoint configuration passed to this plugin is used to identify\n\/\/ what postgres instance to back up, and how to connect to it. Your\n\/\/ endpoint JSON should look something like this:\n\/\/\n\/\/ {\n\/\/ \"pg_user\":\"username-for-postgres\",\n\/\/ \"pg_password\":\"password-for-above-user\",\n\/\/ \"pg_host\":\"hostname-or-ip-of-pg-server\",\n\/\/ \"pg_port\":\"port-above-pg-server-listens-on\", # defaults to 5432\n\/\/ \"pg_database\": \"name-of-db-to-backup\" # optional\n\/\/ }\n\/\/\n\/\/ The `pg_database` field is optional. If specified, the plugin will only\n\/\/ perform backups of the named database. If not specified (the default), all\n\/\/ databases will be backed up.\n\/\/\n\/\/ BACKUP DETAILS\n\/\/\n\/\/ The `postgres` plugin makes use of `pg_dumpall -c` to back up all databases\n\/\/ on the postgres server it connects to. There is currently no filtering of\n\/\/ individual databases to back up, unless that is done via the postgres users\n\/\/ and roles. The dumps generated include SQL to clean up existing databses\/tables,\n\/\/ so that the restore will go smoothly.\n\/\/\n\/\/ Backing up with the `postgres` plugin will not drop any existing connections to the\n\/\/ database, or restart the service.\n\/\/\n\/\/ RESTORE DETAILS\n\/\/\n\/\/ To restore, the `postgres` plugin connects to the postgres server using the `psql`\n\/\/ command. It then feeds in the backup data (`pg_dumpall` output). To work around\n\/\/ cases where the databases being restored cannot be recreated due to existing connections,\n\/\/ the plugin disallows incoming connections for each database, and disconnects the existing\n\/\/ connections, prior to dropping the database. Once the database is recreated, connections\n\/\/ are once again allowed into the database.\n\/\/\n\/\/ Restoring with the `postgres` plugin will terminate existing connections to the database,\n\/\/ but does not need to restart the postgres service.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ This plugin relies on the `pg_dumpall` and `psql` commands. Please ensure that they\n\/\/ are present on the system that will be running the backups + restores for postgres.\n\/\/ If you are using shield-boshrelease to deploy SHIELD, these tools are provided,

Nats provides multicast, but no guarantees of delivery\nand no flow-control. This works fine as long as your\ndownstream read\/subscribe capacity is larger than your\npublishing rate.\n\nIf your nats publisher evers produces\nfaster than your subscriber can keep up, you may overrun\nyour buffers and drop messages. If your sender is local\nand replaying a disk file of traffic over nats, you are\nguanateed to exhaust even the largest of the internal\nnats client buffers. In addition you may wish guaranteed\norder of delivery (even with dropped messages), which\nswp provides.\n\nHence swp was built to provide flow-control and reliable, ordered\ndelivery on top of the nats event bus. It reproduces the\nTCP sliding window and flow-control mechanism in a\nSession between two nats clients. It provides flow\ncontrol between exactly two nats endpoints; in many\ncases this is sufficient to allow all subscribers to\nkeep up. If you have a wide variation in consumer\nperformance, establish the rate-controlling\n`swp` Session between your producer and your\nslowest consumer.\n\nThere is also a Session.RegisterAsap() API that can be\nused to obtain possibly-out-of-order and possibly-duplicated\nbut as-soon-as-possible delivery (similar to that which\nnats give you natively), while retaining the\nflow-control required to avoid client-buffer overrun.\nThis can be used in tandem with the main always-ordered-and-lossless\nAPI if so desired.\n*\/\npackage swp\n\nimport (\n\t\"fmt\"\n\t\"sync\/atomic\"\n\t\"time\"\n)\n\n\/\/ sliding window protocol\n\/\/\n\/\/ Reference: pp118-120, Computer Networks: A Systems Approach\n\/\/ by Peterson and Davie, Morgan Kaufmann Publishers, 1996.\n\/\/\n\/\/ In addition to sliding window, we implement flow-control\n\/\/ similar to how tcp does for throttling senders.\n\/\/ See pp296-301 of Peterson and Davie.\n\/\/\n\/\/ Most of the implementation is in sender.go and recv.go.\n\n\/\/go:generate msgp\n\n\/\/msgp:ignore TxqSlot RxqSlot Semaphore SenderState RecvState SWP Session NatsNet SimNet\n\n\/\/ Packet is what is transmitted between Sender A and\n\/\/ Recver B, where A and B are the two endpoints in a\n\/\/ given Session.

Nats provides multicast, but no guarantees of delivery\nand no flow-control. This works fine as long as your\ndownstream read\/subscribe capacity is larger than your\npublishing rate.\n\nIf your nats publisher evers produces\nfaster than your subscriber can keep up, you may overrun\nyour buffers and drop messages. If your sender is local\nand replaying a disk file of traffic over nats, you are\nguanateed to exhaust even the largest of the internal\nnats client buffers. In addition you may wish guaranteed\norder of delivery (even with dropped messages), which\nswp provides.\n\nHence swp was built to provide flow-control and reliable, ordered\ndelivery on top of the nats event bus. It reproduces the\nTCP sliding window and flow-control mechanism in a\nSession between two nats clients. It provides flow\ncontrol between exactly two nats endpoints; in many\ncases this is sufficient to allow all subscribers to\nkeep up. If you have a wide variation in consumer\nperformance, establish the rate-controlling\nswp Session between your producer and your\nslowest consumer.\n\nThere is also a Session.RegisterAsap() API that can be\nused to obtain possibly-out-of-order and possibly-duplicated\nbut as-soon-as-possible delivery (similar to that which\nnats give you natively), while retaining the\nflow-control required to avoid client-buffer overrun.\nThis can be used in tandem with the main always-ordered-and-lossless\nAPI if so desired.\n*\/\npackage swp\n\nimport (\n\t\"fmt\"\n\t\"sync\/atomic\"\n\t\"time\"\n)\n\n\/\/ sliding window protocol\n\/\/\n\/\/ Reference: pp118-120, Computer Networks: A Systems Approach\n\/\/ by Peterson and Davie, Morgan Kaufmann Publishers, 1996.\n\/\/\n\/\/ In addition to sliding window, we implement flow-control\n\/\/ similar to how tcp does for throttling senders.\n\/\/ See pp296-301 of Peterson and Davie.\n\/\/\n\/\/ Most of the implementation is in sender.go and recv.go.\n\n\/\/go:generate msgp\n\n\/\/msgp:ignore TxqSlot RxqSlot Semaphore SenderState RecvState SWP Session NatsNet SimNet\n\n\/\/ Packet is what is transmitted between Sender A and\n\/\/ Recver B, where A and B are the two endpoints in a\n\/\/ given Session.

You either start a Node from scratch\nusing raft.StartNode or start a Node from some initial state using raft.RestartNode.\n\tstorage := raft.NewMemoryStorage()\n\tn := raft.StartNode(0x01, []int64{0x02, 0x03}, 3, 1, storage)\n\nNow that you are holding onto a Node you have a few responsibilities:\n\nFirst, you must read from the Node.Ready() channel and process the updates\nit contains. This means:\n\n1. Write HardState, Entries, and Snapshot to persistent storage if they are\nnot empty. Note that when writing an Entry with Index i, any\npreviously-persisted entries with Index >= i must be discarded.\n\n2. Send all Messages to the nodes named in the To field. It is important\nthat this happen *after* all state has been persisted.\n\n3. Apply Snapshot (if any) and CommittedEntries to the state machine.\nIf any committed Entry has Type EntryConfChange, call Node.ApplyConfChange()\nafter applying it.\n\n4. Call Node.Advance() to signal readiness for the next batch of updates.\nThis may be done at any time after step 1, although all updates must be processed\nin the order they were returned by Ready.\n\nSecond, all persisted log entries must be made available via an\nimplementation of the Storage interface. The provided MemoryStorage\ntype can be used for this (if you repopulate its state upon a\nrestart), or you can supply your own disk-backed implementation.\n\nThird, when you receive a message from another node, pass it to Node.Step:\n\n\tfunc recvRaftRPC(ctx context.Context, m raftpb.Message) {\n\t\tn.Step(ctx, m)\n\t}\n\nFinally, you need to call Node.Tick() at regular intervals (probably\nvia a time.Ticker). Raft has two important timeouts: heartbeat and the\nelection timeout. However, internally to the raft package time is\nrepresented by an abstract \"tick\".\n\nThe total state machine handling loop will look something like this:\n\n for {\n select {\n case <-s.Ticker:\n n.Tick()\n case rd := <-s.Node.Ready():\n saveToStorage(rd.State, rd.Entries, rd.Snapshot)\n send(rd.Messages)\n if !raft.IsEmptySnap(rd.Snapshot) {\n processSnapshot(rd.Snapshot)\n }\n for entry := range rd.CommittedEntries {\n process(entry)\n if entry.Type == raftpb.EntryConfChange:\n var cc raftpb.ConfChange\n cc.Unmarshal(entry.Data)\n s.Node.ApplyConfChange(cc)\n }\n s.Node.Advance()\n case <-s.done:\n return\n }\n }\n\nTo propose changes to the state machine from your node take your application\ndata, serialize it into a byte slice and call:\n\n\tn.Propose(ctx, data)\n\nIf the proposal is committed, data will appear in committed entries with type\nraftpb.EntryNormal. There is no guarantee that a proposed command will be\ncommitted; you may have to re-propose after a timeout.\n\nTo add or remove node in a cluster, build ConfChange struct 'cc' and call:\n\n\tn.ProposeConfChange(ctx, cc)\n\nAfter config change is committed, some committed entry with type\nraftpb.EntryConfChange will be returned. You must apply it to node through:\n\n\tvar cc raftpb.ConfChange\n\tcc.Unmarshal(data)\n\tn.ApplyConfChange(cc)\n\nNote: An ID represents a unique node in a cluster for all time. A\ngiven ID MUST be used only once even if the old node has been removed.\nThis means that for example IP addresses make poor node IDs since they\nmay be reused.\n\nImplementation notes\n\nThis implementation is up to date with the final Raft thesis\n(https:\/\/ramcloud.stanford.edu\/~ongaro\/thesis.pdf), although our\nimplementation of the membership change protocol differs somewhat from\nthat described in chapter 4. The key invariant that membership changes\nhappen one node at a time is preserved, but in our implementation the\nmembership change takes effect when its entry is applied, not when it\nis added to the log (so the entry is committed under the old\nmembership instead of the new). This is equivalent in terms of safety,\nsince the old and new configurations are guaranteed to overlap.\n\nTo ensure that we do not attempt to commit two membership changes at\nonce by matching log positions (which would be unsafe since they\nshould have different quorum requirements), we simply disallow any\nproposed membership change while any uncommitted change appears in\nthe leader's log.\n\n*\/\npackage raft\n<commit_msg>raft: more doc updates.<commit_after>\/\/ Copyright 2015 CoreOS, Inc.\n\/\/\n\/\/ Licensed under the Apache License, Version 2.0 (the \"License\");\n\/\/ you may not use this file except in compliance with the License.\n\/\/ You may obtain a copy of the License at\n\/\/\n\/\/ http:\/\/www.apache.org\/licenses\/LICENSE-2.0\n\/\/\n\/\/ Unless required by applicable law or agreed to in writing, software\n\/\/ distributed under the License is distributed on an \"AS IS\" BASIS,\n\/\/ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n\/\/ See the License for the specific language governing permissions and\n\/\/ limitations under the License.\n\n\/*\nPackage raft provides an implementation of the raft consensus algorithm.\n\nUsage\n\nThe primary object in raft is a Node.

The configuration change may be cancelled at this point\nby setting the NodeID field to zero before calling ApplyConfChange\n(but ApplyConfChange must be called one way or the other, and the decision to cancel\nmust be based solely on the state machine and not external information such as\nthe observed health of the node).\n\n4.

positions (which would be unsafe since they\nshould have different quorum requirements), we simply disallow any\nproposed membership change while any uncommitted change appears in\nthe leader's log.\n\nThis approach introduces a problem when you try to remove a member\nfrom a two-member cluster: If one of the members dies before the\nother one receives the commit of the confchange entry, then the member\ncannot be removed any more since the cluster cannot make progress.\nFor this reason it is highly recommened to use three or more nodes in\nevery cluster.\n\n*\/\npackage

The file\n also contains a cryptographic checksum to avoid unauthorized\n modifications.\n\nCOMMANDS\n This section contains a list of commands supported by hush. The\n command name should be the second argument on the command line when\n invoking hush.\n\n export\n Exports the decrypted contents of your hush file to stdout.\n Each line represents a leaf and the path to that leaf. Each\n line is split into two columns, separated by a tab character.\n The first column is a slash-separated path.

Currently, all docker containers receive their own mount\n\/\/ namespaces. NsenterMounter works by executing nsenter to run commands in\n\/\/ the host's mount namespace.\n\/\/\n\/\/ NsenterMounter requires:\n\/\/\n\/\/ 1. Docker >= 1.6 due to the dependency on the slave propagation mode\n\/\/ of the bind-mount of the kubelet root directory in the container.\n\/\/ Docker 1.5 used a private propagation mode for bind-mounts, so mounts\n\/\/ performed in the host's mount namespace do not propagate out to the\n\/\/ bind-mount in this docker version.\n\/\/ 2. The host's root filesystem must be available at \/rootfs\n\/\/ 3. The nsenter binary must be on the Kubelet process' PATH in the container's\n\/\/ filesystem.\n\/\/ 4. The Kubelet process must have CAP_SYS_ADMIN (required by nsenter); at\n\/\/ the present, this effectively means that the kubelet is running in a\n\/\/ privileged container.\n\/\/ 5.

Currently, all docker containers receive their own mount\n\/\/ namespaces. NsenterMounter works by executing nsenter to run commands in\n\/\/ the host's mount namespace.\n\/\/\n\/\/ NsenterMounter requires:\n\/\/\n\/\/ 1. Docker >= 1.6 due to the dependency on the slave propagation mode\n\/\/ of the bind-mount of the kubelet root directory in the container.\n\/\/ Docker 1.5 used a private propagation mode for bind-mounts, so mounts\n\/\/ performed in the host's mount namespace do not propagate out to the\n\/\/ bind-mount in this docker version.\n\/\/ 2. The host's root filesystem must be available at \/rootfs\n\/\/ 3. The nsenter binary must be on the Kubelet process' PATH in the container's\n\/\/ filesystem.\n\/\/ 4. The Kubelet process must have CAP_SYS_ADMIN (required by nsenter); at\n\/\/ the present, this effectively means that the kubelet is running in a\n\/\/ privileged container.\n\/\/ 5. The volume path used by the Kubelet must be the same inside and outside\n\/\/ the container and be writable by the container (to initialize volume)\n\/\/ contents.

If it is, fail.\n\t\tepic.Fail(t, today, birthday)\n\t}\n\nIn the previous example the first validation will fail, here's what that would look like in go test's output:\n\n\t### mytests.TestEpicExample in filename.go at line 8\n\t--- QOTF: Huston, we have a problem!\n\t--- GOT : 2014-05-19\n\t--- WANT: 1982-02-28\n\t--- FAIL: TestEpicExample (0.00 seconds)\n\nEasy to read and fun, isn't it?\n\nXYZ Not Supported\n\nNo worries, if you're using epic then you're writing a normal test case using \"go test\" and the \"testing\" package, feel\nfree to leverage those tools when working with epic to cover your needs; epic will never add support for non-generic\ncases as it's meant to stay simple, easy to use and fun!\n\nContributions\n\nWant to contribute? The best way is to open a pull request on Github at https:\/\/github.com\/federico-lox\/epic.\n\nIn particular you can help making testing everyone's code more fun by adding new QOTFs.\n\n*\/\npackage epic\n\nimport (\n\t\"fmt\"\n\t\"math\/rand\"\n\t\"path\/filepath\"\n\t\"reflect\"\n\t\"runtime\"\n\t\"testing\"\n\t\"time\"\n)\n\nconst (\n\tindexReset = -1\n\tqotfLabel = \"QOTF\"\n\tgotLabel = \"GOT\"\n\twantLabel = \"WANT\"\n\tnotLabel = \"(not) \"\n\treportFormat = \"### %s in %s at line %d\\n--- %-4s: %s\\n--- %-4s: %v\\n--- %-4s: %s%v\\n\"\n)\n\nvar (\n\textractContext = context\n\theadlinesIndex = indexReset\n\theadlines = []string{\n\t\t\"Uh-oh...\",\n\t\t\"Huston, we have a problem!\",\n\t\t\"Oh boy!\",\n\t\t\"Gimme 10 bucks and I'll make all your problems disappear *wink*\",\n\t\t\"To fail or not to fail, that is the question...\",\n\t\t\"Talk me out of it!\",\n\t\t\"I'm outta here!!!\",\n\t\t\"Holy failing tests, Batman!\",\n\t\t\"One can always count on you, uh?\",\n\t\t\"And the winner is...\",\n\t\t\"You're dead to me...\",\n\t\t\"Well done!

if a Control is marked as being \"filling\", it will be sized to fill its cell.\n\/\/ Even if a Control is marked as filling, its preferred size is used to calculate cell sizes.\n\/\/ One Control can be marked as \"stretchy\": when the Window containing the Grid is resized, the cell containing that Control resizes to take any remaining space; its row and column are adjusted accordingly (so other filling controls in the same row and column will fill to the new height and width, respectively).\n\/\/ A stretchy Control implicitly fills its cell.\n\/\/ All cooridnates in a Grid are given in (row,column) form with (0,0) being the top-left cell.\n\/\/ Unlike other UI toolkit Grids, this Grid does not (yet?

Either or both of the flags may be replaced with the\n\tcharacter '*', causing their values to be obtained from the next\n\toperand, which must be of type int.\n\n\tFor most values, width is the minimum number of characters to output,\n\tpadding the formatted form with spaces if necessary.\n\tFor strings, precision is the maximum number of characters to output,\n\ttruncating if necessary.\n\n\tFor floating-point values, width sets the minimum width of the field and\n\tprecision sets the number of places after the decimal, if appropriate,\n\texcept that for %g\/%G it sets the total number of digits. For example,\n\tgiven 123.45 the format %6.2f prints 123.45 while %.4g prints 123.5.\n\tThe default precision for %e and %f is 6; for %g it is the smallest\n\tnumber of digits necessary to identify the value uniquely.\n\n\tFor complex numbers, the width and precision apply to the two\n\tcomponents independently and the result is parenthsized, so %f applied\n\tto 1.2+3.4i produces (1.200000+3.400000i).\n\n\tOther flags:\n\t\t+\talways print a sign for numeric values;\n\t\t\tguarantee ASCII-only output for %q (%+q)\n\t\t-\tpad with spaces on the right rather than the left (left-justify the field)\n\t\t#\talternate format: add leading 0 for octal (%#o), 0x for hex (%#x);\n\t\t\t0X for hex (%#X); suppress 0x for %p (%#p);\n\t\t\tfor %q, print a raw (backquoted) string if strconv.CanBackquote\n\t\t\treturns true;\n\t\t\twrite e.g. U+0078 'x' if the character is printable for %U (%#U).\n\t\t' '\t(space) leave a space for elided sign in numbers (% d);\n\t\t\tput spaces between bytes printing strings or slices in hex (% x, % X)\n\t\t0\tpad with leading zeros rather than spaces;\n\t\t\tfor numbers, this moves the padding after the sign\n\n\tFlags are ignored by verbs that do not expect them.\n\tFor example there is no alternate decimal format, so %#d and %d\n\tbehave identically.\n\n\tFor each Printf-like function, there is also a Print function\n\tthat takes no format and is equivalent to saying %v for every\n\toperand. Another variant Println inserts blanks between\n\toperands and appends a newline.\n\n\tRegardless of the verb, if an operand is an interface value,\n\tthe internal concrete value is used, not the interface itself.\n\tThus:\n\t\tvar i interface{} = 23\n\t\tfmt.Printf(\"%v\\n\", i)\n\twill print 23.\n\n\tExcept when printed using the the verbs %T and %p, special\n\tformatting considerations apply for operands that implement\n\tcertain interfaces. In order of application:\n\n\t1. If an operand implements the Formatter interface, it will\n\tbe invoked. Formatter provides fine control of formatting.\n\n\t2. If the %v verb is used with the # flag (%#v) and the operand\n\timplements the GoStringer interface, that will be invoked.\n\n\tIf the format (which is implicitly %v for Println etc.) is valid\n\tfor a string (%s %q %v %x %X), the following two rules apply:\n\n\t3. If an operand implements the error interface, the Error method\n\twill be invoked to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\t4. If an operand implements method String() string, that method\n\twill be invoked to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\tFor compound operands such as slices and structs, the format\n\tapplies to the elements of each operand, recursively, not to the\n\toperand as a whole. Thus %q will quote each element of a slice\n\tof strings, and %6.2f will control formatting for each element\n\tof a floating-point array.\n\n\tTo avoid recursion in cases such as\n\t\ttype X string\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", x) }\n\tconvert the value before recurring:\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", string(x)) }\n\n\tExplicit argument indexes:\n\n\tIn Printf, Sprintf, and Fprintf, the default behavior is for each\n\tformatting verb to format successive arguments passed in the call.\n\tHowever, the notation [n] immediately before the verb indicates that the\n\tnth one-indexed argument is to be formatted instead. The same notation\n\tbefore a '*' for a width or precision selects the argument index holding\n\tthe value. After processing a bracketed expression [n], arguments n+1,\n\tn+2, etc. will be processed unless otherwise directed.\n\n\tFor example,\n\t\tfmt.Sprintf(\"%[2]d %[1]d\\n\", 11, 22)\n\twill yield \"22, 11\", while\n\t\tfmt.Sprintf(\"%[3]*.[2]*[1]f\", 12.0, 2, 6),\n\tequivalent to\n\t\tfmt.Sprintf(\"%6.2f\", 12.0),\n\twill yield \" 12.00\". Because an explicit index affects subsequent verbs,\n\tthis notation can be used to print the same values multiple times\n\tby resetting the index for the first argument to be repeated:\n\t\tfmt.Sprintf(\"%d %d %#[1]x %#x\", 16, 17)\n\twill yield \"16 17 0x10 0x11\".\n\n\tFormat errors:\n\n\tIf an invalid argument is given for a verb, such as providing\n\ta string to %d, the generated string will contain a\n\tdescription of the problem, as in these examples:\n\n\t\tWrong type or unknown verb: %!verb(type=value)\n\t\t\tPrintf(\"%d\", hi): %!d(string=hi)\n\t\tToo many arguments: %!(EXTRA type=value)\n\t\t\tPrintf(\"hi\", \"guys\"): hi%!(EXTRA string=guys)\n\t\tToo few arguments: %!verb(MISSING)\n\t\t\tPrintf(\"hi%d\"): hi %!d(MISSING)\n\t\tNon-int for width or precision: %!(BADWIDTH) or %!(BADPREC)\n\t\t\tPrintf(\"%*s\", 4.5, \"hi\"): %!(BADWIDTH)hi\n\t\t\tPrintf(\"%.*s\", 4.5, \"hi\"): %!(BADPREC)hi\n\t\tInvalid or invalid use of argument index: %!(BADINDEX)\n\t\t\tPrintf(\"%*[2]d\", 7): %!d(BADINDEX)\n\t\t\tPrintf(\"%.[2]d\", 7): %!d(BADINDEX)\n\n\tAll errors begin with the string \"%!\" followed sometimes\n\tby a single character (the verb) and end with a parenthesized\n\tdescription.\n\n\tIf an Error or String method triggers a panic when called by a\n\tprint routine, the fmt package reformats the error message\n\tfrom the panic, decorating it with an indication that it came\n\tthrough the fmt package. For example, if a String method\n\tcalls panic(\"bad\"), the resulting formatted message will look\n\tlike\n\t\t%!s(PANIC=bad)\n\n\tThe %!s just shows the print verb in use when the failure\n\toccurred.\n\n\tScanning\n\n\tAn analogous set of functions scans formatted text to yield\n\tvalues. Scan, Scanf and Scanln read from os.Stdin; Fscan,\n\tFscanf and Fscanln read from a specified io.Reader; Sscan,\n\tSscanf and Sscanln read from an argument string. Scanln,\n\tFscanln and Sscanln stop scanning at a newline and require that\n\tthe items be followed by one; Scanf, Fscanf and Sscanf require\n\tnewlines in the input to match newlines in the format; the other\n\troutines treat newlines as spaces.\n\n\tScanf, Fscanf, and Sscanf parse the arguments according to a\n\tformat string, analogous to that of Printf. For example, %x\n\twill scan an integer as a hexadecimal number, and %v will scan\n\tthe default representation format for the value.\n\n\tThe formats behave analogously to those of Printf with the\n\tfollowing exceptions:\n\n\t\t%p is not implemented\n\t\t%T is not implemented\n\t\t%e %E %f %F %g %G are all equivalent and scan any floating point or complex value\n\t\t%s and %v on strings scan a space-delimited token\n\t\tFlags # and + are not implemented.\n\n\tThe familiar base-setting prefixes 0 (octal) and 0x\n\t(hexadecimal) are accepted when scanning integers without a\n\tformat or with the %v verb.\n\n\tWidth is interpreted in the input text (%5s means at most\n\tfive runes of input will be read to scan a string) but there\n\tis no syntax for scanning with a precision (no %5.2f, just\n\t%5f).\n\n\tWhen scanning with a format, all non-empty runs of space\n\tcharacters (except newline) are equivalent to a single\n\tspace in both the format and the input. With that proviso,\n\ttext in the format string must match the input text; scanning\n\tstops if it does not, with the return value of the function\n\tindicating the number of arguments scanned.\n\n\tIn all the scanning functions, a carriage return followed\n\timmediately by a newline is treated as a plain newline\n\t(\\r\\n means the same as \\n).\n\n\tIn all the scanning functions, if an operand implements method\n\tScan (that is, it implements the Scanner interface) that\n\tmethod will be used to scan the text for that operand. Also,\n\tif the number of arguments scanned is less than the number of\n\targuments provided, an error is returned.\n\n\tAll arguments to be scanned must be either pointers to basic\n\ttypes or implementations of the Scanner interface.\n\n\tNote: Fscan etc. can read one character (rune) past the input\n\tthey return, which means that a loop calling a scan routine\n\tmay skip some of the input. This is usually a problem only\n\twhen there is no space between input values. If the reader\n\tprovided to Fscan implements ReadRune, that method will be used\n\tto read characters. If the reader also implements UnreadRune,\n\tthat method will be used to save the character and successive\n\tcalls will not lose data.

Well-formed data that does not fit\n\/\/ into val is discarded.\n\/\/\n\/\/ For example, given these definitions:\n\/\/\n\/\/\ttype Email struct {\n\/\/\t\tWhere string \"attr\";\n\/\/\t\tAddr string;\n\/\/\t}\n\/\/\n\/\/\ttype Result struct {\n\/\/\t\tXMLName xml.Name \"result\";\n\/\/\t\tName string;\n\/\/\t\tPhone string;\n\/\/\t\tEmail []Email;\n\/\/\t}\n\/\/\n\/\/\tvar result = Result{ \"name\", \"phone\", nil }\n\/\/\n\/\/ unmarshalling the XML input\n\/\/\n\/\/\t<result>\n\/\/\t\t<email where=\"home\">\n\/\/\t\t\t<addr>gre@example.com<\/addr>\n\/\/\t\t<\/email>\n\/\/\t\t<email where='work'>\n\/\/\t\t\t<addr>gre@work.com<\/addr>\n\/\/\t\t<\/email>\n\/\/\t\t<name>Grace R.

Well-formed data that does not fit\n\/\/ into val is discarded.\n\/\/\n\/\/ For example, given these definitions:\n\/\/\n\/\/\ttype Email struct {\n\/\/\t\tWhere string \"attr\";\n\/\/\t\tAddr string;\n\/\/\t}\n\/\/\n\/\/\ttype Result struct {\n\/\/\t\tXMLName xml.Name \"result\";\n\/\/\t\tName string;\n\/\/\t\tPhone string;\n\/\/\t\tEmail []Email;\n\/\/\t}\n\/\/\n\/\/\tvar result = Result{ \"name\", \"phone\", nil }\n\/\/\n\/\/ unmarshalling the XML input\n\/\/\n\/\/\t<result>\n\/\/\t\t<email where=\"home\">\n\/\/\t\t\t<addr>gre@example.com<\/addr>\n\/\/\t\t<\/email>\n\/\/\t\t<email where='work'>\n\/\/\t\t\t<addr>gre@work.com<\/addr>\n\/\/\t\t<\/email>\n\/\/\t\t<name>Grace R. Emlin<\/name>\n\/\/\t\t<address>123 Main Street<\/address>\n\/\/\t<\/result>\n\/\/\n\/\/ via Unmarshal(r, &result) is equivalent to assigning\n\/\/\n\/\/\tr = Result{\n\/\/\t\txml.Name{\"\", \"result\"},\n\/\/\t\t\"Grace R.

Unmarshal uses a case-insensitive\n\/\/ comparison to match XML element names to struct field names.\n\/\/\n\/\/ Unmarshal maps an XML element to a struct using the following rules:\n\/\/\n\/\/ * If the struct has a field named XMLName of type xml.Name,\n\/\/ Unmarshal records the element name in that field.\n\/\/\n\/\/ * If the XMLName field has an associated tag string of the form\n\/\/ \"tag\" or \"namespace-URL tag\", the XML element must have\n\/\/ the given tag (and, optionally, name space) or else Unmarshal\n\/\/ returns an error.\n\/\/\n\/\/ * If the XML element has an attribute whose name matches a\n\/\/ struct field of type string with tag \"attr\", Unmarshal records\n\/\/ the attribute value in that field.\n\/\/\n\/\/ * If the XML element contains character data, that data is\n\/\/ accumulated in the first struct field that has tag \"chardata\".\n\/\/ The struct field may have type []byte or string.\n\/\/ If there is no such field, the character data is discarded.\n\/\/\n\/\/ * If the XML element contains a sub-element whose name\n\/\/ matches a struct field whose tag is neither \"attr\" nor \"chardata\",\n\/\/ Unmarshal maps the sub-element to that struct field.\n\/\/ Otherwise, if the struct has a field named Any, unmarshal\n\/\/ maps the sub-element to that struct field.\n\/\/\n\/\/ Unmarshal maps an XML element to a string or []byte by saving the\n\/\/ concatenation of that elements character data in the string or []byte.\n\/\/\n\/\/ Unmarshal maps an XML element to a slice by extending the length\n\/\/ of the slice and mapping the element to the newly created value.\n\/\/\n\/\/ Unmarshal maps an XML element to a bool by setting the bool to true.\n\/\/\n\/\/ Unmarshal maps an XML element to an xml.Name by recording the\n\/\/ element name.\n\/\/\n\/\/ Unmarshal maps an XML element to a pointer by setting the pointer\n\/\/ to a freshly allocated value and then mapping the element to that value.\n\/\/\nfunc Unmarshal(r io.Reader,
