Subject: [PATCH 06/72] feat!: Begin using new microgenerator for v2 firestore
 (#91)

* Update synth.py to use new generator

* Run generator

* Delete gapic, proto directories, old generated surface

* manual changes for regeneration

* docs: use multiprocessing includes instead of note for multiprocessing

* test: drop coverage to get merged, open tracking issue to raise again

+        name (str):
+            A field name of the form
+            ``projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id}/fields/{field_path}``
+
+            A field path may be a simple field name, e.g. ``address`` or
+            a path to fields within map_value , e.g. ``address.city``,
+            or a special field path. The only valid special field is
+            ``*``, which represents any field.
+
+            Field paths may be quoted using
+            ``(backtick). The only character that needs to be escaped within a quoted field path is the backtick character itself, escaped using a backslash. Special characters in field paths that must be quoted include:``\ \*\ ``,``.\ :literal:`, ``` (backtick),`\ [``,``]`,
+            as well as any ascii symbolic characters.
+
+            Examples: (Note: Comments here are written in markdown
+            syntax, so there is an additional layer of backticks to
+            represent a code block)
+            ``\``\ address.city\`\ ``represents a field named``\ address.city\ ``, not the map key``\ city\ ``in the field``\ address\ ``.``\ \`\ *\`\ ``represents a field named``*\ \`,
+            not any field.
+
+            A special ``Field`` contains the default indexing settings

-      name:
-          The resource name of the document, for example ``projects/{pro
-          ject_id}/databases/{database_id}/documents/{document_path}``.
-      fields:
-          The document's fields.  The map keys represent field names.  A
-          simple field name contains only characters ``a`` to ``z``,
-          ``A`` to ``Z``, ``0`` to ``9``, or ``_``, and must not start
-          with ``0`` to ``9``. For example, ``foo_bar_17``.  Field names
-          matching the regular expression ``__.*__`` are reserved.
-          Reserved field names are forbidden except in certain
-          documented contexts. The map keys, represented as UTF-8, must
-          not exceed 1,500 bytes and cannot be empty.  Field paths may
-          be used in other contexts to refer to structured fields
-          defined here. For ``map_value``, the field path is represented
-          by the simple or quoted field names of the containing fields,
-          delimited by ``.``. For example, the structured field ``"foo"
-          : { map_value: { "x&y" : { string_value: "hello" }}}`` would
-          be represented by the field path ``foo.x&y``.  Within a field
-          path, a quoted field name starts and ends with ````` and may
-          contain any character. Some characters, including `````, must
-          be escaped using a ``\``. For example, ```x&y``` represents
-          ``x&y`` and ```bak\`tik``` represents ``bak`tik``.
-      create_time:
-          Output only. The time at which the document was created.  This
-          value increases monotonically when a document is deleted then
-          recreated. It can also be compared to values from other
-          documents and the ``read_time`` of a query.
-      update_time:
-          Output only. The time at which the document was last changed.
-          This value is initially set to the ``create_time`` then
-          increases monotonically with each change to the document. It
-          can also be compared to values from other documents and the
-          ``read_time`` of a query.

-      order_by:
-          The order to apply to the query results.  Firestore guarantees
-          a stable ordering through the following rules:  -  Any field
-          required to appear in ``order_by``, that is not already
-          specified in ``order_by``, is appended to the order in field
-          name    order by default. -  If an order on ``__name__`` is
-          not specified, it is appended by    default.  Fields are
-          appended with the same sort direction as the last order
-          specified, or 'ASCENDING' if no order was specified. For
-          example:  -  ``SELECT * FROM Foo ORDER BY A`` becomes
-          ``SELECT * FROM Foo ORDER BY A, __name__`` -  ``SELECT * FROM
-          Foo ORDER BY A DESC`` becomes    ``SELECT * FROM Foo ORDER BY
-          A DESC, __name__ DESC`` -  ``SELECT * FROM Foo WHERE A > 1``

-          __name__``
-      start_at:
-          A starting point for the query results.
-      end_at:
-          A end point for the query results.
-      offset:
-          The number of results to skip.  Applies before limit, but
-          after all other constraints. Must be >= 0 if specified.
-      limit:
-          The maximum number of results to return.  Applies after all
-          other constraints. Must be >= 0 if specified.

-        set_to_server_value:
-            Sets the field to the given server value.
-        increment:
-            Adds the given value to the field's current value.  This must
-            be an integer or a double value. If the field is not an
-            integer or double, or if the field does not yet exist, the
-            transformation will set the field to the given value. If
-            either of the given value or the current field value are
-            doubles, both values will be interpreted as doubles. Double
-            arithmetic and representation of double values follow IEEE 754
-            semantics. If there is positive/negative integer overflow, the
-            field is resolved to the largest magnitude positive/negative
-            integer.
-        maximum:
-            Sets the field to the maximum of its current value and the
-            given value.  This must be an integer or a double value. If
-            the field is not an integer or double, or if the field does
-            not yet exist, the transformation will set the field to the

-            and the input value are of mixed types (that is - one is an
-            integer and one is a double) the field takes on the type of
-            the larger operand. If the operands are equivalent (e.g. 3 and
-            3.0), the field does not change. 0, 0.0, and -0.0 are all
-            zero. The maximum of a zero stored value and zero input value
-            is always the stored value. The maximum of any numeric value x
-            and NaN is NaN.
-        minimum:
-            Sets the field to the minimum of its current value and the
-            given value.  This must be an integer or a double value. If
-            the field is not an integer or double, or if the field does
-            not yet exist, the transformation will set the field to the
-            input value. If a minimum operation is applied where the field
-            and the input value are of mixed types (that is - one is an
-            integer and one is a double) the field takes on the type of
-            the smaller operand. If the operands are equivalent (e.g. 3
-            and 3.0), the field does not change. 0, 0.0, and -0.0 are all
-            zero. The minimum of a zero stored value and zero input value
-            is always the stored value. The minimum of any numeric value x
-            and NaN is NaN.
-        append_missing_elements:
-            Append the given elements in order if they are not already
-            present in the current field value. If the field is not an
-            array, or if the field does not yet exist, it is first set to
-            the empty array.  Equivalent numbers of different types (e.g.
-            3L and 3.0) are considered equal when checking if a value is
-            missing. NaN is equal to NaN, and Null is equal to Null. If
-            the input contains multiple equivalent values, only the first
-            will be considered.  The corresponding transform\_result will
-            be the null value.
-        remove_all_from_array:
-            Remove all of the given elements from the array in the field.
-            If the field is not an array, or if the field does not yet
-            exist, it is set to the empty array.  Equivalent numbers of
-            the different types (e.g. 3L and 3.0) are considered equal
-            when deciding whether an element should be removed. NaN is
-            equal to NaN, and Null is equal to Null. This will remove all

+
+            A simple field name contains only characters ``a`` to ``z``,
+            ``A`` to ``Z``, ``0`` to ``9``, or ``_``, and must not start
+            with ``0`` to ``9``. For example, ``foo_bar_17``.

+
+            Field paths may be used in other contexts to refer to

+            characters, including :literal:`\``, must be escaped using a
+            ``\``. For example, :literal:`\`x&y\`` represents ``x&y``

-
-  This API provides several administrative services for Cloud Firestore.
-
-  # Concepts
-
-  Project, Database, Namespace, Collection, and Document are used as defined in
-  the Google Cloud Firestore API.
-
-  Operation: An Operation represents work being performed in the background.
-
-
-  # Services
-
-  ## Index
-
-  The index service manages Cloud Firestore indexes.
-
-  Index creation is performed asynchronously.
-  An Operation resource is created for each such asynchronous operation.
-  The state of the operation (including any errors encountered)
-  may be queried via the Operation resource.
-
-  ## Metadata
-
-  Provides metadata and statistical information about data in Cloud Firestore.
-  The data provided as part of this API may be stale.
-
-  ## Operation
-
-  The Operations collection provides a record of actions performed for the
-  specified Project (including any Operations in progress). Operations are not
-  created directly but through calls on other collections or resources.
-
-  An Operation that is not yet done may be cancelled. The request to cancel is
-  asynchronous and the Operation may continue to run for some time after the
-  request to cancel is made.
-
-  An Operation that is done may be deleted so that it is no longer listed as
-  part of the Operation collection.
-
-  Operations are created by service `FirestoreAdmin`, but are accessed via
-  service `google.longrunning.Operations`.

-    If the index already exists, the call will return an `ALREADY_EXISTS`
-    status.
-
-    During creation, the process could result in an error, in which case the
-    index will move to the `ERROR` state. The process can be recovered by
-    fixing the data that caused the error, removing the index with
-    [delete][google.firestore.admin.v1beta1.FirestoreAdmin.DeleteIndex], then re-creating the index with

-      name:
-          The resource name of the document, for example ``projects/{pro
-          ject_id}/databases/{database_id}/documents/{document_path}``.
-      fields:
-          The document's fields.  The map keys represent field names.  A
-          simple field name contains only characters ``a`` to ``z``,
-          ``A`` to ``Z``, ``0`` to ``9``, or ``_``, and must not start
-          with ``0`` to ``9``. For example, ``foo_bar_17``.  Field names
-          matching the regular expression ``__.*__`` are reserved.
-          Reserved field names are forbidden except in certain
-          documented contexts. The map keys, represented as UTF-8, must
-          not exceed 1,500 bytes and cannot be empty.  Field paths may
-          be used in other contexts to refer to structured fields
-          defined here. For ``map_value``, the field path is represented
-          by the simple or quoted field names of the containing fields,
-          delimited by ``.``. For example, the structured field ``"foo"
-          : { map_value: { "x&y" : { string_value: "hello" }}}`` would
-          be represented by the field path ``foo.x&y``.  Within a field
-          path, a quoted field name starts and ends with ````` and may
-          contain any character. Some characters, including `````, must
-          be escaped using a ``\``. For example, ```x&y``` represents
-          ``x&y`` and ```bak\`tik``` represents ``bak`tik``.
-      create_time:
-          Output only. The time at which the document was created.  This
-          value increases monotonically when a document is deleted then
-          recreated. It can also be compared to values from other
-          documents and the ``read_time`` of a query.
-      update_time:
-          Output only. The time at which the document was last changed.
-          This value is initially set to the ``create_time`` then
-          increases monotonically with each change to the document. It
-          can also be compared to values from other documents and the
-          ``read_time`` of a query.

-// *    `create_time` - The time at which a document was created. Changes only

-// *    `update_time` - The time at which a document was last updated. Changes
-//      every time a document is modified. Does not change when a write results
-//      in no modifications. Increases in a strict monotonic fashion.
-// *    `read_time` - The time at which a particular state was observed. Used
-//      to denote a consistent snapshot of the database or the time at which a
-//      Document was observed to not exist.
-// *    `commit_time` - The time at which the writes in a transaction were
-//      committed. Any read with an equal or greater `read_time` is guaranteed
-//      to see the effects of the transaction.

-// The Cloud Firestore Admin API.
-//
-// This API provides several administrative services for Cloud Firestore.
-//
-// # Concepts
-//
-// Project, Database, Namespace, Collection, and Document are used as defined in
-// the Google Cloud Firestore API.
-//
-// Operation: An Operation represents work being performed in the background.
-//
-//
-// # Services
-//
-// ## Index
-//
-// The index service manages Cloud Firestore indexes.
-//
-// Index creation is performed asynchronously.
-// An Operation resource is created for each such asynchronous operation.
-// The state of the operation (including any errors encountered)
-// may be queried via the Operation resource.
-//
-// ## Metadata
-//
-// Provides metadata and statistical information about data in Cloud Firestore.
-// The data provided as part of this API may be stale.
-//
-// ## Operation
-//
-// The Operations collection provides a record of actions performed for the
-// specified Project (including any Operations in progress). Operations are not
-// created directly but through calls on other collections or resources.
-//
-// An Operation that is not yet done may be cancelled. The request to cancel is
-// asynchronous and the Operation may continue to run for some time after the
-// request to cancel is made.
-//
-// An Operation that is done may be deleted so that it is no longer listed as
-// part of the Operation collection.
-//
-// Operations are created by service `FirestoreAdmin`, but are accessed via
-// service `google.longrunning.Operations`.
-service FirestoreAdmin {

-  // A newly created index's initial state is `CREATING`. On completion of the

-  // If the index already exists, the call will return an `ALREADY_EXISTS`
-  // status.
-  //
-  // During creation, the process could result in an error, in which case the
-  // index will move to the `ERROR` state. The process can be recovered by
-  // fixing the data that caused the error, removing the index with
-  // [delete][google.firestore.admin.v1beta1.FirestoreAdmin.DeleteIndex], then re-creating the index with

-        set_to_server_value:
-            Sets the field to the given server value.
-        increment:
-            Adds the given value to the field's current value.  This must
-            be an integer or a double value. If the field is not an
-            integer or double, or if the field does not yet exist, the
-            transformation will set the field to the given value. If
-            either of the given value or the current field value are
-            doubles, both values will be interpreted as doubles. Double
-            arithmetic and representation of double values follow IEEE 754
-            semantics. If there is positive/negative integer overflow, the
-            field is resolved to the largest magnitude positive/negative
-            integer.
-        maximum:
-            Sets the field to the maximum of its current value and the
-            given value.  This must be an integer or a double value. If
-            the field is not an integer or double, or if the field does
-            not yet exist, the transformation will set the field to the

-            and the input value are of mixed types (that is - one is an
-            integer and one is a double) the field takes on the type of
-            the larger operand. If the operands are equivalent (e.g. 3 and
-            3.0), the field does not change. 0, 0.0, and -0.0 are all
-            zero. The maximum of a zero stored value and zero input value
-            is always the stored value. The maximum of any numeric value x
-            and NaN is NaN.
-        minimum:
-            Sets the field to the minimum of its current value and the
-            given value.  This must be an integer or a double value. If
-            the field is not an integer or double, or if the field does
-            not yet exist, the transformation will set the field to the
-            input value. If a minimum operation is applied where the field
-            and the input value are of mixed types (that is - one is an
-            integer and one is a double) the field takes on the type of
-            the smaller operand. If the operands are equivalent (e.g. 3
-            and 3.0), the field does not change. 0, 0.0, and -0.0 are all
-            zero. The minimum of a zero stored value and zero input value
-            is always the stored value. The minimum of any numeric value x
-            and NaN is NaN.
-        append_missing_elements:
-            Append the given elements in order if they are not already
-            present in the current field value. If the field is not an
-            array, or if the field does not yet exist, it is first set to
-            the empty array.  Equivalent numbers of different types (e.g.
-            3L and 3.0) are considered equal when checking if a value is
-            missing. NaN is equal to NaN, and Null is equal to Null. If
-            the input contains multiple equivalent values, only the first
-            will be considered.  The corresponding transform\_result will
-            be the null value.
-        remove_all_from_array:
-            Remove all of the given elements from the array in the field.
-            If the field is not an array, or if the field does not yet
-            exist, it is set to the empty array.  Equivalent numbers of
-            the different types (e.g. 3L and 3.0) are considered equal
-            when deciding whether an element should be removed. NaN is
-            equal to NaN, and Null is equal to Null. This will remove all

+    This service exposes several types of comparable timestamps:
+
+    -  ``create_time`` - The time at which a document was created.
+       Changes only when a document is deleted, then re-created.
+       Increases in a strict monotonic fashion.
+    -  ``update_time`` - The time at which a document was last updated.
+       Changes every time a document is modified. Does not change when a
+       write results in no modifications. Increases in a strict
+       monotonic fashion.
+    -  ``read_time`` - The time at which a particular state was
+       observed. Used to denote a consistent snapshot of the database or
+       the time at which a Document was observed to not exist.
+    -  ``commit_time`` - The time at which the writes in a transaction
+       were committed. Any read with an equal or greater ``read_time``
+       is guaranteed to see the effects of the transaction.
+
+    This class defines the same methods as the primary client, so the
+    primary client can load the underlying transport implementation
+    and call it.
+
+    It sends protocol buffers over the wire using gRPC (which is built on
+    top of HTTP/2); the ``grpcio`` package must be installed.

+Install PortAudio
++++++++++++++++++
+
+Install `PortAudio`_. This is required by the `PyAudio`_ library to stream
+audio from your computer's microphone. PyAudio depends on PortAudio for cross-platform compatibility, and is installed differently depending on the
+platform.
+
+* For Mac OS X, you can use `Homebrew`_::
+
+      brew install portaudio
+
+  **Note**: if you encounter an error when running `pip install` that indicates
+  it can't find `portaudio.h`, try running `pip install` with the following
+  flags::
+
+      pip install --global-option='build_ext' \
+          --global-option='-I/usr/local/include' \
+          --global-option='-L/usr/local/lib' \
+          pyaudio
+
+* For Debian / Ubuntu Linux::
+
+      apt-get install portaudio19-dev python-all-dev
+
+* Windows may work without having to install PortAudio explicitly (it will get
+  installed with PyAudio).
+
+For more details, see the `PyAudio installation`_ page.

-
-    The Cloud Firestore service.
-
-    This service exposes several types of comparable timestamps:
-
-    -  ``create_time`` - The time at which a document was created.
-       Changes only when a document is deleted, then re-created.
-       Increases in a strict monotonic fashion.
-    -  ``update_time`` - The time at which a document was last updated.
-       Changes every time a document is modified. Does not change when a
-       write results in no modifications. Increases in a strict
-       monotonic fashion.
-    -  ``read_time`` - The time at which a particular state was
-       observed. Used to denote a consistent snapshot of the database or
-       the time at which a Document was observed to not exist.
-    -  ``commit_time`` - The time at which the writes in a transaction
-       were committed. Any read with an equal or greater ``read_time``
-       is guaranteed to see the effects of the transaction.
-
-    This class defines the same methods as the primary client, so the
-    primary client can load the underlying transport implementation
-    and call it.
-
-    It sends protocol buffers over the wire using gRPC (which is built on
-    top of HTTP/2); the ``grpcio`` package must be installed.

Subject: [PATCH 47/72] tests: drop min coverage to 97% (#191)

Toward https://github.com/googleapis/python-firestore/issues/190

Note that this is a short-term fix, to get builds against `master`
passing while work goes on to bring coverage back to 100%.

-Note on Editable Installs / Develop Mode
-========================================
-
-- As mentioned previously, using ``setuptools`` in `develop mode`_
-  or a ``pip`` `editable install`_ is not possible with this
-  library. This is because this library uses `namespace packages`_.
-  For context see `Issue #2316`_ and the relevant `PyPA issue`_.
-
-  Since ``editable`` / ``develop`` mode can't be used, packages
-  need to be installed directly. Hence your changes to the source
-  tree don't get incorporated into the **already installed**
-  package.

Subject: [PATCH 54/72] tests: re-enable cross-language conformance tests
 (#205)

Leaving existing (old) conftest JSON files in place for now. in order
to  get the conftest runner working using existing semantics,
before updating the JSON files and making required changes (to use
'update_transforms', for instance) in a future PR.

Closes #95.

Subject: [PATCH 56/72] feat: use 'update_transforms' (#219)

Update `pbs_for_create`, `pbs_for_set_no_merge`, `pbs_for_set_with_merge`, and `pbs_for_update` to match semantics expected by current versions of [conformance tests](https://github.com/googleapis/conformance-tests/commit/0bb8520e48c35b3e0dd45c328a1b38be35664b91):

- Rather than create separate `Write.transform` messages to hold field transforms, inline them as `update_transforms` in the main `Write.update` message (which will always be created now).

Copy in the current version of the conftest JSON files and verify.

Closes #217

Subject: [PATCH 59/72] chore: restore coverage (almost) to 100% (#225)

Note that the synthtool-generated `.coveragerc` (see #224) does *not* include all changes needed for 100% coverage:  see:

- https://github.com/googleapis/gapic-generator-python/issues/171
- https://github.com/googleapis/gapic-generator-python/issues/437

Closes #92.
Closes #195.

+# 2.0.0 Migration Guide
+
+The 2.0 release of the `google-cloud-firestore` client is a significant upgrade based on a [next-gen code generator](https://github.com/googleapis/gapic-generator-python), and includes substantial interface changes. Existing code written for earlier versions of this library may require updates to use this version. This document describes the changes that have been made, and what you need to do to update your usage.
+
+If you experience issues or have questions, please file an [issue](https://github.com/googleapis/python-firestore/issues).
+
+## Supported Python Versions
+
+> **WARNING**: Breaking change
+
+The 2.0.0 release requires Python 3.6+.
+
+
+## Method Calls
+
+> **WARNING**: Breaking change
+
+If you previously were using modules or functions under the namespace
+`google.cloud.firestore_v1.gapic` there is a high likelihood you have incompatible code.
+To assist with this, we have included some helpful scripts to make some of the code
+modifications required to use 2.0.0.
+
+* Install the library
+
+```py
+python3 -m pip install google-cloud-firestore
+```
+
+* The scripts `fixup_firestore_v1_keywords.py` and `fixup_firestore_admin_v1_keywords.py` 
+is shipped with the library. It expects an input directory (with the code to convert)
+and an empty destination directory.
+
+```sh
+$ fixup_firestore_v1_keywords.py --input-directory .samples/ --output-directory samples/
+$ fixup_firestore_admin_v1_keywords.py --input-directory .samples/ --output-directory samples/
+```
+
+### More Details
+
+In `google-cloud-firestore<2.0.0`, parameters required by the API were positional parameters and optional parameters were keyword parameters.
+
+**Before:**
+```py
+    def a_method(
+        self,
+        param1,
+        param2,
+        param3,
+        retry=google.api_core.gapic_v1.method.DEFAULT,
+        timeout=google.api_core.gapic_v1.method.DEFAULT,
+        metadata=None,
+    ):
+```
+
+In the 2.0.0 release, all methods have a single positional parameter `request`. Method docstrings indicate whether a parameter is required or optional.
+
+Some methods have additional keyword only parameters. The available parameters depend on the `google.api.method_signature` annotation specified by the API producer.
+
+
+**After:**
+```py
+    def a_method(
+        self,
+        request: RequestType = None,
+        *
+        param1,
+        param2,
+        param3,
+        retry=google.api_core.gapic_v1.method.DEFAULT,
+        timeout=google.api_core.gapic_v1.method.DEFAULT,
+        metadata=None,
+    ):
+```
+
+> **NOTE:** The `request` parameter and flattened keyword parameters for the API are mutually exclusive.
+> Passing both will result in an error.
+
+
+Both of these calls are valid:
+
+```py
+response = client.a_method(
+    request={
+        "param1": param1,
+        "param2": param2,
+        "param3": param3
+    }
+)
+```
+
+```py
+response = client.a_method(
+    param1=param1,
+    param2=param2,
+    param3=param3
+)
+```
+
+This call is invalid because it mixes `request` with a keyword argument `param1`. Executing this code
+will result in an error.
+
+```py
+response = client.a_method(
+    request={
+        "param1": param1,
+        "param2": param2
+    },
+    param2=param2
+)
+```
+
+
+
+## Enums and Types
+
+
+> **WARNING**: Breaking change
+
+The `enums` submodule has been removed.
+
+**Before:**
+```py
+from google.cloud import firestore_v1
+
+direction = firestore_v1.enums.StructuredQuery.Direction.ASCENDING
+```
+
+
+**After:**
+```py
+from google.cloud import firestore_v1
+
+direction = firestore_v1.types.StructuredQuery.Direction.ASCENDING
+```

+> **NOTE:** The `request` parameter and flattened keyword parameters for the API are mutually exclusive.
+> Passing both will result in an error.
+
+
+Both of these calls are valid:
+
+```py
+response = client.a_method(
+    request={
+        "param1": param1,
+        "param2": param2,
+        "param3": param3
+    }
+)
+```
+
+```py
+response = client.a_method(
+    param1=param1,
+    param2=param2,
+    param3=param3
+)
+```
+
+This call is invalid because it mixes `request` with a keyword argument `param1`. Executing this code
+will result in an error.
+
+```py
+response = client.a_method(
+    request={
+        "param1": param1,
+        "param2": param2
+    },
+    param2=param2
+)
+```
+
+
+
+## Enums and Types
+
+
+> **WARNING**: Breaking change
+
+The submodules `enums` and `types` have been removed.
+
+**Before:**
+```py
+from google.cloud import firestore_v1
+
+direction = firestore_v1.enums.StructuredQuery.Direction.ASCENDING
+```
+
+
+**After:**
+```py
+from google.cloud import firestore_v1
+
+direction = firestore_v1.types.StructuredQuery.Direction.ASCENDING
+```
