"""BigQuery sources and sinks.
This module implements reading from and writing to BigQuery tables. It relies
on several classes exposed by the BigQuery API: TableSchema, TableFieldSchema,
TableRow, and TableCell. The default mode is to return table rows read from a
BigQuery source as dictionaries. Similarly a Write transform to a BigQuerySink
accepts PCollections of dictionaries. This is done for more convenient
programming. If desired, the native TableRow objects can be used throughout to
represent rows (use an instance of TableRowJsonCoder as a coder argument when
creating the sources or sinks respectively).
Also, for programming convenience, instances of TableReference and TableSchema
have a string representation that can be used for the corresponding arguments:
- TableReference can be a PROJECT:DATASET.TABLE or DATASET.TABLE string.
- TableSchema can be a NAME:TYPE{,NAME:TYPE}* string
(e.g. 'month:STRING,event_count:INTEGER').
The syntax supported is described here:
https://cloud.google.com/bigquery/bq-command-line-tool-quickstart
BigQuery sources can be used as main inputs or side inputs. A main input
(common case) is expected to be massive and will be split into manageable chunks
and processed in parallel. Side inputs are expected to be small and will be read
completely every time a ParDo DoFn gets executed. In the example below the
lambda function implementing the DoFn for the Map transform will get on each
call *one* row of the main table and *all* rows of the side table. The runner
may use some caching techniques to share the side inputs between calls in order
to avoid excessive reading:::
main_table = pipeline | 'VeryBig' >> beam.io.ReadFromBigQuery(...)
side_table = pipeline | 'NotBig' >> beam.io.ReadFromBigQuery(...)
results = (
main_table
| 'ProcessData' >> beam.Map(
lambda element, side_input: ..., AsList(side_table)))
There is no difference in how main and side inputs are read. What makes the
side_table a 'side input' is the AsList wrapper used when passing the table
as a parameter to the Map transform. AsList signals to the execution framework
that its input should be made available whole.
The main and side inputs are implemented differently. Reading a BigQuery table
as main input entails exporting the table to a set of GCS files (in AVRO or in
JSON format) and then processing those files.
Users may provide a query to read from rather than reading all of a BigQuery
table. If specified, the result obtained by executing the specified query will
be used as the data of the input transform.::
query_results = pipeline | beam.io.gcp.bigquery.ReadFromBigQuery(
query='SELECT year, mean_temp FROM samples.weather_stations')
When creating a BigQuery input transform, users should provide either a query
or a table. Pipeline construction will fail with a validation error if neither
or both are specified.
When reading via `ReadFromBigQuery`, bytes are returned decoded as bytes.
This is due to the fact that ReadFromBigQuery uses Avro exports by default.
When reading from BigQuery using `apache_beam.io.BigQuerySource`, bytes are
returned as base64-encoded bytes. To get base64-encoded bytes using
`ReadFromBigQuery`, you can use the flag `use_json_exports` to export
data as JSON, and receive base64-encoded bytes.
ReadAllFromBigQuery
-------------------
Beam 2.27.0 introduces a new transform called `ReadAllFromBigQuery` which
allows you to define table and query reads from BigQuery at pipeline
runtime.:::
read_requests = p | beam.Create([
ReadFromBigQueryRequest(query='SELECT * FROM mydataset.mytable'),
ReadFromBigQueryRequest(table='myproject.mydataset.mytable')])
results = read_requests | ReadAllFromBigQuery()
A good application for this transform is in streaming pipelines to
refresh a side input coming from BigQuery. This would work like so:::
side_input = (
p
| 'PeriodicImpulse' >> PeriodicImpulse(
first_timestamp, last_timestamp, interval, True)
| 'MapToReadRequest' >> beam.Map(
lambda x: ReadFromBigQueryRequest(table='dataset.table'))
| beam.io.ReadAllFromBigQuery())
main_input = (
p
| 'MpImpulse' >> beam.Create(sample_main_input_elements)
|
'MapMpToTimestamped' >> beam.Map(lambda src: TimestampedValue(src, src))
| 'WindowMpInto' >> beam.WindowInto(
window.FixedWindows(main_input_windowing_interval)))
result = (
main_input
| 'ApplyCrossJoin' >> beam.FlatMap(
cross_join, rights=beam.pvalue.AsIter(side_input)))
**Note**: This transform is supported on Portable and Dataflow v2 runners.
**Note**: This transform does not currently clean up temporary datasets
created for its execution. (BEAM-11359)
Writing Data to BigQuery
========================
The `WriteToBigQuery` transform is the recommended way of writing data to
BigQuery. It supports a large set of parameters to customize how you'd like to
write to BigQuery.
Table References
----------------
This transform allows you to provide static `project`, `dataset` and `table`
parameters which point to a specific BigQuery table to be created. The `table`
parameter can also be a dynamic parameter (i.e. a callable), which receives an
element to be written to BigQuery, and returns the table that that element
should be sent to.
You may also provide a tuple of PCollectionView elements to be passed as side
inputs to your callable. For example, suppose that one wishes to send
events of different types to different tables, and the table names are
computed at pipeline runtime, one may do something like the following::
with Pipeline() as p:
elements = (p | beam.Create([
{'type': 'error', 'timestamp': '12:34:56', 'message': 'bad'},
{'type': 'user_log', 'timestamp': '12:34:59', 'query': 'flu symptom'},
]))
table_names = (p | beam.Create([
('error', 'my_project:dataset1.error_table_for_today'),
('user_log', 'my_project:dataset1.query_table_for_today'),
])
table_names_dict = beam.pvalue.AsDict(table_names)
elements | beam.io.gcp.bigquery.WriteToBigQuery(
table=lambda row, table_dict: table_dict[row['type']],
table_side_inputs=(table_names_dict,))
In the example above, the `table_dict` argument passed to the function in
`table_dict` is the side input coming from `table_names_dict`, which is passed
as part of the `table_side_inputs` argument.
Schemas
---------
This transform also allows you to provide a static or dynamic `schema`
parameter (i.e. a callable).
If providing a callable, this should take in a table reference (as returned by
the `table` parameter), and return the corresponding schema for that table.
This allows to provide different schemas for different tables::
def compute_table_name(row):
...
errors_schema = {'fields': [
{'name': 'type', 'type': 'STRING', 'mode': 'NULLABLE'},
{'name': 'message', 'type': 'STRING', 'mode': 'NULLABLE'}]}
queries_schema = {'fields': [
{'name': 'type', 'type': 'STRING', 'mode': 'NULLABLE'},
{'name': 'query', 'type': 'STRING', 'mode': 'NULLABLE'}]}
with Pipeline() as p:
elements = (p | beam.Create([
{'type': 'error', 'timestamp': '12:34:56', 'message': 'bad'},
{'type': 'user_log', 'timestamp': '12:34:59', 'query': 'flu symptom'},
]))
elements | beam.io.gcp.bigquery.WriteToBigQuery(
table=compute_table_name,
schema=lambda table: (errors_schema
if 'errors' in table
else queries_schema))
It may be the case that schemas are computed at pipeline runtime. In cases
like these, one can also provide a `schema_side_inputs` parameter, which is
a tuple of PCollectionViews to be passed to the schema callable (much like
the `table_side_inputs` parameter).
Additional Parameters for BigQuery Tables
-----------------------------------------
This sink is able to create tables in BigQuery if they don't already exist. It
also relies on creating temporary tables when performing file loads.
The WriteToBigQuery transform creates tables using the BigQuery API by
inserting a load job (see the API reference [1]), or by inserting a new table
(see the API reference for that [2][3]).
When creating a new BigQuery table, there are a number of extra parameters
that one may need to specify. For example, clustering, partitioning, data
encoding, etc. It is possible to provide these additional parameters by
passing a Python dictionary as `additional_bq_parameters` to the transform.
As an example, to create a table that has specific partitioning, and
clustering properties, one would do the following::
additional_bq_parameters = {
'timePartitioning': {'type': 'DAY'},
'clustering': {'fields': ['country']}}
with Pipeline() as p:
elements = (p | beam.Create([
{'country': 'mexico', 'timestamp': '12:34:56', 'query': 'acapulco'},
{'country': 'canada', 'timestamp': '12:34:59', 'query': 'influenza'},
]))
elements | beam.io.gcp.bigquery.WriteToBigQuery(
table='project_name1:dataset_2.query_events_table',
additional_bq_parameters=additional_bq_parameters)
Much like the schema case, the parameter with `additional_bq_parameters` can
also take a callable that receives a table reference.

*** Short introduction to BigQuery concepts ***
Tables have rows (TableRow) and each row has cells (TableCell).
A table has a schema (TableSchema), which in turn describes the schema of each
cell (TableFieldSchema). The terms field and cell are used interchangeably.
TableSchema: Describes the schema (types and order) for values in each row.
Has one attribute, 'field', which is list of TableFieldSchema objects.
TableFieldSchema: Describes the schema (type, name) for one field.
Has several attributes, including 'name' and 'type'. Common values for
the type attribute are: 'STRING', 'INTEGER', 'FLOAT', 'BOOLEAN', 'NUMERIC',
'GEOGRAPHY'.
All possible values are described at:
https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types
TableRow: Holds all values in a table row. Has one attribute, 'f', which is a
list of TableCell instances.
TableCell: Holds the value for one cell (or field). Has one attribute,
'v', which is a JsonValue instance. This class is defined in
apitools.base.py.extra_types.py module.
As of Beam 2.7.0, the NUMERIC data type is supported. This data type supports
high-precision decimal numbers (precision of 38 digits, scale of 9 digits).
The GEOGRAPHY data type works with Well-Known Text (See
https://en.wikipedia.org/wiki/Well-known_text) format for reading and writing
to BigQuery.
BigQuery IO requires values of BYTES datatype to be encoded using base64
encoding when writing to BigQuery.

Args:
table (str): The ID of the table. The ID must contain only letters
``a-z``, ``A-Z``, numbers ``0-9``, or underscores ``_``. If
**dataset** argument is :data:`None` then the table argument must
contain the entire table reference specified as: ``'DATASET.TABLE'`` or
``'PROJECT:DATASET.TABLE'``.
dataset (str): The ID of the dataset containing this table or
:data:`None` if the table reference is specified entirely by the table
argument.
project (str): The ID of the project containing this table or
:data:`None` if the table reference is specified entirely by the table
argument.
schema (str): The schema to be used if the BigQuery table to write has
to be created. This can be either specified as a
:class:`~apache_beam.io.gcp.internal.clients.bigquery.\
bigquery_v2_messages.TableSchema` object or a single string of the form
``'field1:type1,field2:type2,field3:type3'`` that defines a comma
separated list of fields. Here ``'type'`` should specify the BigQuery
type of the field. Single string based schemas do not support nested
fields, repeated fields, or specifying a BigQuery mode for fields (mode
will always be set to ``'NULLABLE'``).
create_disposition (BigQueryDisposition): A string describing what
happens if the table does not exist. Possible values are:
* :attr:`BigQueryDisposition.CREATE_IF_NEEDED`: create if does not
exist.
* :attr:`BigQueryDisposition.CREATE_NEVER`: fail the write if does not
exist.
write_disposition (BigQueryDisposition): A string describing what
happens if the table has already some data. Possible values are:
* :attr:`BigQueryDisposition.WRITE_TRUNCATE`: delete existing rows.
* :attr:`BigQueryDisposition.WRITE_APPEND`: add to existing rows.
* :attr:`BigQueryDisposition.WRITE_EMPTY`: fail the write if table not
empty.
validate (bool): If :data:`True`, various checks will be done when sink
gets initialized (e.g., is table present given the disposition
arguments?). This should be :data:`True` for most scenarios in order to
catch errors as early as possible (pipeline construction instead of
pipeline execution). It should be :data:`False` if the table is created
during pipeline execution by a previous step.
coder (~apache_beam.coders.coders.Coder): The coder for the
table rows if serialized to disk. If :data:`None`, then the default
coder is :class:`~apache_beam.io.gcp.bigquery_tools.RowAsDictJsonCoder`,
which will interpret every element written to the sink as a dictionary
that will be JSON serialized as a line in a file. This argument needs a
value only in special cases when writing table rows as dictionaries is
not desirable.
kms_key (str): Optional Cloud KMS key name for use when creating new
tables.
Raises:
TypeError: if the schema argument is not a :class:`str` or a
:class:`~apache_beam.io.gcp.internal.clients.bigquery.\
bigquery_v2_messages.TableSchema` object.
ValueError: if the table reference as a string does not
match the expected format.

"""Initialize a WriteToBigQuery transform.
Args:
table (str, callable, ValueProvider): The ID of the table, or a callable
that returns it. The ID must contain only letters ``a-z``, ``A-Z``,
numbers ``0-9``, or connectors ``-_``. If dataset argument is
:data:`None` then the table argument must contain the entire table
reference specified as: ``'DATASET.TABLE'``
or ``'PROJECT:DATASET.TABLE'``. If it's a callable, it must receive one
argument representing an element to be written to BigQuery, and return
a TableReference, or a string table name as specified above.
dataset (str): The ID of the dataset containing this table or
:data:`None` if the table reference is specified entirely by the table
argument.
project (str): The ID of the project containing this table or
:data:`None` if the table reference is specified entirely by the table
argument.
schema (str,dict,ValueProvider,callable): The schema to be used if the
BigQuery table to write has to be created. This can be either specified
as a :class:`~apache_beam.io.gcp.internal.clients.bigquery.\
bigquery_v2_messages.TableSchema`. or a `ValueProvider` that has a JSON string,
or a python dictionary, or the string or dictionary itself,
object or a single string of the form
``'field1:type1,field2:type2,field3:type3'`` that defines a comma
separated list of fields. Here ``'type'`` should specify the BigQuery
type of the field. Single string based schemas do not support nested
fields, repeated fields, or specifying a BigQuery mode for fields
(mode will always be set to ``'NULLABLE'``).
If a callable, then it should receive a destination (in the form of
a str, and return a str, dict or TableSchema).
One may also pass ``SCHEMA_AUTODETECT`` here when using JSON-based
file loads, and BigQuery will try to infer the schema for the files
that are being loaded.
create_disposition (BigQueryDisposition): A string describing what
happens if the table does not exist. Possible values are:
* :attr:`BigQueryDisposition.CREATE_IF_NEEDED`: create if does not
exist.
* :attr:`BigQueryDisposition.CREATE_NEVER`: fail the write if does not
exist.
write_disposition (BigQueryDisposition): A string describing what happens
if the table has already some data. Possible values are:
* :attr:`BigQueryDisposition.WRITE_TRUNCATE`: delete existing rows.
* :attr:`BigQueryDisposition.WRITE_APPEND`: add to existing rows.
* :attr:`BigQueryDisposition.WRITE_EMPTY`: fail the write if table not
empty.
For streaming pipelines WriteTruncate can not be used.
kms_key (str): Optional Cloud KMS key name for use when creating new
tables.
batch_size (int): Number of rows to be written to BQ per streaming API
insert. The default is 500.
test_client: Override the default bigquery client used for testing.
max_file_size (int): The maximum size for a file to be written and then
loaded into BigQuery. The default value is 4TB, which is 80% of the
limit of 5TB for BigQuery to load any file.
max_files_per_bundle(int): The maximum number of files to be concurrently
written by a worker. The default here is 20. Larger values will allow
writing to multiple destinations without having to reshard - but they
increase the memory burden on the workers.
custom_gcs_temp_location (str): A GCS location to store files to be used
for file loads into BigQuery. By default, this will use the pipeline's
temp_location, but for pipelines whose temp_location is not appropriate
for BQ File Loads, users should pass a specific one.
method: The method to use to write to BigQuery. It may be
STREAMING_INSERTS, FILE_LOADS, or DEFAULT. An introduction on loading
data to BigQuery: https://cloud.google.com/bigquery/docs/loading-data.
DEFAULT will use STREAMING_INSERTS on Streaming pipelines and
FILE_LOADS on Batch pipelines.
insert_retry_strategy: The strategy to use when retrying streaming inserts
into BigQuery. Options are shown in bigquery_tools.RetryStrategy attrs.
Default is to retry always. This means that whenever there are rows
that fail to be inserted to BigQuery, they will be retried indefinitely.
Other retry strategy settings will produce a deadletter PCollection
as output. Appropriate values are:
* `RetryStrategy.RETRY_ALWAYS`: retry all rows if
there are any kind of errors. Note that this will hold your pipeline
back if there are errors until you cancel or update it.
* `RetryStrategy.RETRY_NEVER`: rows with errors
will not be retried. Instead they will be output to a dead letter
queue under the `'FailedRows'` tag.
* `RetryStrategy.RETRY_ON_TRANSIENT_ERROR`: retry
rows with transient errors (e.g. timeouts). Rows with permanent errors
will be output to dead letter queue under `'FailedRows'` tag.
additional_bq_parameters (callable): A function that returns a dictionary
with additional parameters to pass to BQ when creating / loading data
into a table. These can be 'timePartitioning', 'clustering', etc. They
are passed directly to the job load configuration. See
https://cloud.google.com/bigquery/docs/reference/rest/v2/Job#jobconfigurationload
table_side_inputs (tuple): A tuple with ``AsSideInput`` PCollections to be
passed to the table callable (if one is provided).
schema_side_inputs: A tuple with ``AsSideInput`` PCollections to be
passed to the schema callable (if one is provided).
triggering_frequency (int): Every triggering_frequency duration, a
BigQuery load job will be triggered for all the data written since
the last load job. BigQuery has limits on how many load jobs can be
triggered per day, so be careful not to set this duration too low, or
you may exceed daily quota. Often this is set to 5 or 10 minutes to
ensure that the project stays well under the BigQuery quota.
See https://cloud.google.com/bigquery/quota-policy for more information
about BigQuery quotas.
validate: Indicates whether to perform validation checks on
inputs. This parameter is primarily used for testing.
temp_file_format: The format to use for file loads into BigQuery. The
options are NEWLINE_DELIMITED_JSON or AVRO, with NEWLINE_DELIMITED_JSON
being used by default. For advantages and limitations of the two
formats, see
https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-avro
and
https://cloud.google.com/bigquery/docs/loading-data-cloud-storage-json.
ignore_insert_ids: When using the STREAMING_INSERTS method to write data
to BigQuery, `insert_ids` are a feature of BigQuery that support
deduplication of events. If your use case is not sensitive to
duplication of data inserted to BigQuery, set `ignore_insert_ids`
to True to increase the throughput for BQ writing. See:
https://cloud.google.com/bigquery/streaming-data-into-bigquery#disabling_best_effort_de-duplication
with_auto_sharding: Experimental. If true, enables using a dynamically
determined number of shards to write to BigQuery. This can be used for
both FILE_LOADS and STREAMING_INSERTS. Only applicable to unbounded
input.

default.
Args:
table (str, callable, ValueProvider): The ID of the table, or a callable
that returns it. The ID must contain only letters ``a-z``, ``A-Z``,
numbers ``0-9``, or underscores ``_``. If dataset argument is
:data:`None` then the table argument must contain the entire table
reference specified as: ``'DATASET.TABLE'``
or ``'PROJECT:DATASET.TABLE'``. If it's a callable, it must receive one
argument representing an element to be written to BigQuery, and return
a TableReference, or a string table name as specified above.
dataset (str): The ID of the dataset containing this table or
:data:`None` if the table reference is specified entirely by the table
argument.
project (str): The ID of the project containing this table.
query (str, ValueProvider): A query to be used instead of arguments
table, dataset, and project.
validate (bool): If :data:`True`, various checks will be done when source
gets initialized (e.g., is table present?). This should be
:data:`True` for most scenarios in order to catch errors as early as
possible (pipeline construction instead of pipeline execution). It
should be :data:`False` if the table is created during pipeline
execution by a previous step.
coder (~apache_beam.coders.coders.Coder): The coder for the table
rows. If :data:`None`, then the default coder is
_JsonToDictCoder, which will interpret every row as a JSON
serialized dictionary.
use_standard_sql (bool): Specifies whether to use BigQuery's standard SQL
dialect for this query. The default value is :data:`False`.
If set to :data:`True`, the query will use BigQuery's updated SQL
dialect with improved standards compliance.
This parameter is ignored for table inputs.
flatten_results (bool): Flattens all nested and repeated fields in the
query results. The default value is :data:`True`.
kms_key (str): Optional Cloud KMS key name for use when creating new
temporary tables.
gcs_location (str, ValueProvider): The name of the Google Cloud Storage
bucket where the extracted table should be written as a string or
a :class:`~apache_beam.options.value_provider.ValueProvider`. If
:data:`None`, then the temp_location parameter is used.
bigquery_job_labels (dict): A dictionary with string labels to be passed
to BigQuery export and query jobs created by this transform. See:
https://cloud.google.com/bigquery/docs/reference/rest/v2/\
Job#JobConfiguration
use_json_exports (bool): By default, this transform works by exporting
BigQuery data into Avro files, and reading those files. With this
parameter, the transform will instead export to JSON files. JSON files
are slower to read due to their larger size.
When using JSON exports, the BigQuery types for DATE, DATETIME, TIME, and
TIMESTAMP will be exported as strings. This behavior is consistent with
BigQuerySource.
When using Avro exports, these fields will be exported as native Python
types (datetime.date, datetime.datetime, datetime.datetime,
and datetime.datetime respectively). Avro exports are recommended.
To learn more about BigQuery types, and Time-related type
representations, see: https://cloud.google.com/bigquery/docs/reference/\

"""
SequenceMatcher is a flexible class for comparing pairs of sequences of
any type, so long as the sequence elements are hashable. The basic
algorithm predates, and is a little fancier than, an algorithm
published in the late 1980's by Ratcliff and Obershelp under the
hyperbolic name "gestalt pattern matching". The basic idea is to find
the longest contiguous matching subsequence that contains no "junk"
elements (R-O doesn't address junk). The same idea is then applied
recursively to the pieces of the sequences to the left and to the right
of the matching subsequence. This does not yield minimal edit
sequences, but does tend to yield matches that "look right" to people.
SequenceMatcher tries to compute a "human-friendly diff" between two
sequences. Unlike e.g. UNIX(tm) diff, the fundamental notion is the
longest *contiguous* & junk-free matching subsequence. That's what
catches peoples' eyes. The Windows(tm) windiff has another interesting
notion, pairing up elements that appear uniquely in each sequence.
That, and the method here, appear to yield more intuitive difference
reports than does diff. This method appears to be the least vulnerable
to synching up on blocks of "junk lines", though (like blank lines in
ordinary text files, or maybe "<P>" lines in HTML files). That may be
because this is the only method of the 3 that has a *concept* of
"junk" <wink>.
Example, comparing two strings, and considering blanks to be "junk":
>>> s = SequenceMatcher(lambda x: x == " ",
... "private Thread currentThread;",
... "private volatile Thread currentThread;")
>>>
.ratio() returns a float in [0, 1], measuring the "similarity" of the
sequences. As a rule of thumb, a .ratio() value over 0.6 means the
sequences are close matches:
>>> print(round(s.ratio(), 3))
0.866
>>>
If you're only interested in where the sequences match,
.get_matching_blocks() is handy:
>>> for block in s.get_matching_blocks():
... print("a[%d] and b[%d] match for %d elements" % block)
a[0] and b[0] match for 8 elements
a[8] and b[17] match for 21 elements
a[29] and b[38] match for 0 elements
Note that the last tuple returned by .get_matching_blocks() is always a
dummy, (len(a), len(b), 0), and this is the only case in which the last
tuple element (number of elements matched) is 0.
If you want to know how to change the first sequence into the second,
use .get_opcodes():
>>> for opcode in s.get_opcodes():
... print("%6s a[%d:%d] b[%d:%d]" % opcode)
equal a[0:8] b[0:8]
insert a[8:8] b[8:17]
equal a[8:29] b[17:38]
See the Differ class for a fancy human-friendly file differencer, which
uses SequenceMatcher both to compare sequences of lines, and to compare
sequences of characters within similar (near-matching) lines.
See also function get_close_matches() in this module, which shows how
simple code building on SequenceMatcher can be used to do useful work.
Timing: Basic R-O is cubic time worst case and quadratic time expected
case. SequenceMatcher is quadratic time for the worst case and has
expected-case behavior dependent in a complicated way on how many
elements the sequences have in common; best case time is linear.

the resulting block never matches on junk except as identical junk
happens to be adjacent to an "interesting" match.
Here's the same example as before, but considering blanks to be
junk. That prevents " abcd" from matching the " abcd" at the tail
end of the second sequence directly. Instead only the "abcd" can
match, and matches the leftmost "abcd" in the second sequence:

class Differ:
r"""
Differ is a class for comparing sequences of lines of text, and
producing human-readable differences or deltas. Differ uses
SequenceMatcher both to compare sequences of lines, and to compare
sequences of characters within similar (near-matching) lines.
Each line of a Differ delta begins with a two-letter code:
'- ' line unique to sequence 1
'+ ' line unique to sequence 2
' ' line common to both sequences
'? ' line not present in either input sequence
Lines beginning with '? ' attempt to guide the eye to intraline
differences, and were not present in either input sequence. These lines
can be confusing if the sequences contain tab characters.
Note that Differ makes no claim to produce a *minimal* diff. To the
contrary, minimal diffs are often counter-intuitive, because they synch
up anywhere possible, sometimes accidental matches 100 pages apart.
Restricting synch points to contiguous matches preserves some notion of
locality, at the occasional cost of producing a longer diff.
Example: Comparing two texts.
First we set up the texts, sequences of individual single-line strings
ending with newlines (such sequences can also be obtained from the
`readlines()` method of file-like objects):
>>> text1 = ''' 1. Beautiful is better than ugly.
... 2. Explicit is better than implicit.
... 3. Simple is better than complex.
... 4. Complex is better than complicated.
... '''.splitlines(keepends=True)
>>> len(text1)
4
>>> text1[0][-1]
'\n'
>>> text2 = ''' 1. Beautiful is better than ugly.
... 3. Simple is better than complex.
... 4. Complicated is better than complex.
... 5. Flat is better than nested.
... '''.splitlines(keepends=True)
Next we instantiate a Differ object:
>>> d = Differ()
Note that when instantiating a Differ object we may pass functions to
filter out line and character 'junk'. See Differ.__init__ for details.
Finally, we compare the two:
>>> result = list(d.compare(text1, text2))
'result' is a list of strings, so let's pretty-print it:
>>> from pprint import pprint as _pprint
>>> _pprint(result)
[' 1. Beautiful is better than ugly.\n',
'- 2. Explicit is better than implicit.\n',
'- 3. Simple is better than complex.\n',
'+ 3. Simple is better than complex.\n',
'? ++\n',
'- 4. Complex is better than complicated.\n',
'? ^ ---- ^\n',
'+ 4. Complicated is better than complex.\n',
'? ++++ ^ ^\n',
'+ 5. Flat is better than nested.\n']
As a single multi-line string it looks like this:
>>> print(''.join(result), end="")
1. Beautiful is better than ugly.
- 2. Explicit is better than implicit.
- 3. Simple is better than complex.
+ 3. Simple is better than complex.
? ++
- 4. Complex is better than complicated.
? ^ ---- ^
+ 4. Complicated is better than complex.
? ++++ ^ ^
+ 5. Flat is better than nested.

The two optional keyword parameters are for filter functions:
- `linejunk`: A function that should accept a single string argument,

`IS_LINE_JUNK` may be used to filter out lines without visible
characters, except for at most one splat ('#'). It is recommended
to leave linejunk None; as of Python 2.3, the underlying
SequenceMatcher class has grown an adaptive notion of "noise" lines
that's better than any static definition the author has ever been
able to craft.
- `charjunk`: A function that should accept a string of length 1. The
module-level function `IS_CHARACTER_JUNK` may be used to filter out
whitespace characters (a blank or tab; **note**: bad idea to include
newline in this!). Use of IS_CHARACTER_JUNK is recommended.

Compare `a` and `b` (lists of strings); return a `Differ`-style delta.
Optional keyword parameters `linejunk` and `charjunk` are for filter
functions (or None):
- linejunk: A function that should accept a single string argument, and
return true iff the string is junk. The default is None, and is
recommended; as of Python 2.3, an adaptive notion of "noise" lines is
used that does a good job on its own.
- charjunk: A function that should accept a string of length 1. The
default is module-level function IS_CHARACTER_JUNK, which filters out
whitespace characters (a blank or tab; note: bad idea to include newline
in this!).
Tools/scripts/ndiff.py is a command-line front-end to this function.
Example:
>>> diff = ndiff('one\ntwo\nthree\n'.splitlines(keepends=True),
... 'ore\ntree\nemu\n'.splitlines(keepends=True))
>>> print(''.join(diff), end="")

Enumerations are typically defined as a list of tuples. The exported values are
typically munged into other types or classes at module load time.

together and easier to audit. And, maybe even one day this file will be
automatically generated by scanning the libclang headers!

Automatically creates project tasks from procurement lines.
===========================================================
This module will automatically create a new task for each procurement order line
(e.g. for sale order lines), if the corresponding product meets the following
characteristics:
* Product Type = Service
* Procurement Method (Order fulfillment) = MTO (Make to Order)
* Supply/Procurement Method = Manufacture
If on top of that a projet is specified on the product form (in the Procurement
tab), then the new task will be created in that specific project. Otherwise, the
new task will not belong to any project, and may be added to a project manually
later.
When the project task is completed or cancelled, the corresponding procurement
is updated accordingly. For example, if this procurement corresponds to a sale
order line, the sale order line will be considered delivered when the task is
completed.

"""ComboBox dropped height Test
**What is checked**
It is ensured that the height of the list displayed when the combobox is
dropped down is not less than the height of the reference.
**How is it checked**
The value for the dropped rectangle can be retrieved from windows. The height
of this rectangle is calculated and compared against the reference height.
**When is a bug reported**
If the height of the dropped rectangle for the combobox being checked is less
than the height of the reference one then a bug is reported.
**Bug Extra Information**
There is no extra information associated with this bug type
**Is Reference dialog needed**
The reference dialog is necessary for this test.
**False positive bug reports**
No false bugs should be reported. If the font of the localised control has a
smaller height than the reference then it is possible that the dropped
rectangle could be of a different size.
**Test Identifier**
The identifier for this test/bug is "ComboBoxDroppedHeight"
