[PATCH v1 1/1] .pytool/Plugin/Uncrustify: Add Uncrustify plugin

[PATCH v1 1/1] .pytool/Plugin/Uncrustify: Add Uncrustify plugin

[Michael Kubacki]

From: Michael Kubacki <michael.kubacki@microsoft.com>

Adds a new CI plugin for Uncrustify. This is used to check
coding standard compliance of source code to the EDK II C Coding
Standards Specification.

An external dependency is added in the plugin directory to retrieve
the Uncrustify executable. Currently, the executable is from an edk2
fork of the application.

The default Uncrustify configuration files are added in the plugin
directory. Additional details are in the Readme.md file added in
the Uncrustify plugin directory.

Note: A V2 is planned that will fail the Uncrustify plugin results
if a file or function template header is found in a formatted file.
This will be additional functionality added in the plugin and will
not change the way Uncrustify is invoked.

+# Uncrustify Plugin
+
+This CiBuildPlugin scans all the files in a given package and checks for coding standard compliance issues.
+
+This plugin requires the directory containing the Uncrustify executable that should be used for this plugin to
+be specified in an environment variable named `UNCRUSTIFY_CI_PATH`. This unique variable name is used to avoid confusion
+with other paths to Uncrustify which might not be the expected build for use by this plugin.
+
+By default, an Uncrustify configuration file named "uncrustify.cfg" located in the same directory as the plugin is
+used. The value can be overridden to a package-specific path with the `ConfigFilePath` configuration file option.
+
+* Uncrustify source code and documentation: https://github.com/uncrustify/uncrustify
+* Project Mu Uncrustify fork source code and documentation: https://dev.azure.com/projectmu/Uncrustify
+
+## Files Checked in a Package
+
+By default, this plugin will discover all files in the package with the following default paths:
+
+```python
+[
+# C source
+"*.c",
+"*.h"
+]
+```
+
+From this list of files, any files ignored by Git or residing in a Git submodule will be removed. If Git is not
+found, submodules are not found, or ignored files are not found no changes are made to the list of discovered files.
+
+To control the paths checked in a given package, review the configuration options described in this file.
+
+## Configuration
+
+The plugin can be configured with a few optional configuration options.
+
+``` yaml
+  "Uncrustify": {
+      "AuditOnly": False,           # Don't fail the build if there are errors. Just log them.
+      "OutputFileDiffs": False      # Output chunks of formatting diffs in the test case log.
+                                    # This can significantly slow down the plugin on very large packages.
+      "ConfigFilePath": "",         # Custom path to an Uncrustify config file. Path is relative to the package.
+      "IgnoreStandardPaths": [],    # Standard Plugin defined paths that should be ignored.
+      "AdditionalIncludePaths": []  # Additional paths to check formatting (wildcards supported).
+  }
+```
+
+### `AdditionalIncludePaths`
+
+A package configuration file can specify any additional paths to be included with this option.
+
+At this time, it is recommended all files run against the plugin be written in the C or C++ language.
+
+### `AuditOnly`
+
+`Boolean` - Default is `False`.
+
+If `True`, run the test in an "audit only mode" which will log all errors but instead of failing the build, it will set
+the test as skipped. This allows visibility into the failures without breaking the build.
+
+### `ConfigFilePath`
+
+`String` - Default is `"uncrustify.cfg"`
+
+When specified in the config file, this is a package relative path to the Uncrustify configuration file.
+
+### `IgnoreStandardPaths`
+
+This plugin by default will check the below standard paths. A package configuration file can specify any of these paths
+to be ignored.
+
+```python
+[
+# C source
+"*.c",
+"*.h"
+]
+```
+
+### `OutputFileDiffs`
+
+`Boolean` - Default is `False`.
+
+If `True`, output diffs of formatting changes into the test case log. This is helpful to exactly understand what changes
+need to be made to the source code in order to fix a coding standard compliance issue.
+
+Note that calculating the file diffs on a very large set of of results (e.g. >100 files) can significantly slow down
+plugin execution.
+
+### `SkipGitExclusions`
+
+`Boolean` - Default is `False`.
+
+By default, files in paths matched in a .gitignore file or a recognized git submodule are excluded. If this option
+is `True`, the plugin will not attempt to recognize these files and exclude them.
+
+## High-Level Plugin Operation
+
+This plugin generates two main sets of temporary files:
+
+  1. A working directory in the directory `Build/{package_name}`
+  2. For each source file with formatting errors, a sibling file with the `.uncrustify_plugin` extension
+
+The working directory contains temporary files unique to operation of the plugin. All of these files are removed on
+exit of the plugin including successful or unsuccessful execution (such as a Python exception occurring). If for any
+reason, any files in the package exist prior to running the plugin with the `.uncrustify_plugin` extension, the plugin
+will inform the user to remove these files and exit before running Uncrustify. This is to ensure the accuracy of the
+results reported from each execution instance of the plugin.
+
+The plugin determines the list of relevant files to check with Uncrustify and then invokes Uncrustify with that file
+list. For any files not compliant to the configuration file provided, Uncrustify will generate a corresponding file
+with the `.uncrustify_plugin` extension. The plugin discovers all of these files. If any such files are present, this
+indicates a formatting issue was found and the test is marked failed (unless `AuditOnly` mode is enabled).
+
+The test case log will contain a report of which files failed to format properly, allowing the user to run Uncrustify
+against the file locally to fix the issue. If the `OutputFileDiffs` configuration option is set to `True`, the plugin
+will output diff chunks for all code formatting issues in the test case log.

Re: [PATCH v1 1/1] .pytool/Plugin/Uncrustify: Add Uncrustify plugin

[Michael D Kinney]

Hi Michael,

Have you opened a BZ for this feature?  Can you do that and add REF: to the commit message?

Also, the template files for uncrustify need to be updated to match the contents
from the EDK II C Coding Standard.  Pease see the file and function header templates
in this location:

    https://github.com/mdkinney/edk2/tree/Bug_3737_ApplyUncrustifyChanges_V4/.uncrustify

I also see you use a temp directory in Build output:

> +        self._working_dir = os.path.join(
> +            self._abs_workspace_path, "Build", self._package_name, "UncrustifyPlugin")

In the EccCheck and LicenseCheck patches I sent earlier today, I decided to put all
temp directories associated with pytools Plugins in the path:

    Build/.pytool/Plugin/<PluginName>

This provide a unique path for temp files associated with Plugins that matches
the source path to the Plugin so plugins will never use the same temp dir path
and each plugin can safely clean up its own temp directory.

Thanks,

Mike

> +## Files Checked in a Package
> +
> +By default, this plugin will discover all files in the package with the following default paths:
> +
> +```python
> +[
> +# C source
> +"*.c",
> +"*.h"
> +]
> +```
> +
> +From this list of files, any files ignored by Git or residing in a Git submodule will be removed. If Git is not
> +found, submodules are not found, or ignored files are not found no changes are made to the list of discovered files.
> +
> +To control the paths checked in a given package, review the configuration options described in this file.
> +
> +## Configuration
> +
> +The plugin can be configured with a few optional configuration options.
> +
> +``` yaml
> +  "Uncrustify": {
> +      "AuditOnly": False,           # Don't fail the build if there are errors. Just log them.
> +      "OutputFileDiffs": False      # Output chunks of formatting diffs in the test case log.
> +                                    # This can significantly slow down the plugin on very large packages.
> +      "ConfigFilePath": "",         # Custom path to an Uncrustify config file. Path is relative to the package.
> +      "IgnoreStandardPaths": [],    # Standard Plugin defined paths that should be ignored.
> +      "AdditionalIncludePaths": []  # Additional paths to check formatting (wildcards supported).
> +  }
> +```
> +
> +### `AdditionalIncludePaths`
> +
> +A package configuration file can specify any additional paths to be included with this option.
> +
> +At this time, it is recommended all files run against the plugin be written in the C or C++ language.
> +
> +### `AuditOnly`
> +
> +`Boolean` - Default is `False`.
> +
> +If `True`, run the test in an "audit only mode" which will log all errors but instead of failing the build, it will set
> +the test as skipped. This allows visibility into the failures without breaking the build.
> +
> +### `ConfigFilePath`
> +
> +`String` - Default is `"uncrustify.cfg"`
> +
> +When specified in the config file, this is a package relative path to the Uncrustify configuration file.
> +
> +### `IgnoreStandardPaths`
> +
> +This plugin by default will check the below standard paths. A package configuration file can specify any of these paths
> +to be ignored.
> +
> +```python
> +[
> +# C source
> +"*.c",
> +"*.h"
> +]
> +```
> +
> +### `OutputFileDiffs`
> +
> +`Boolean` - Default is `False`.
> +
> +If `True`, output diffs of formatting changes into the test case log. This is helpful to exactly understand what changes
> +need to be made to the source code in order to fix a coding standard compliance issue.
> +
> +Note that calculating the file diffs on a very large set of of results (e.g. >100 files) can significantly slow down
> +plugin execution.
> +
> +### `SkipGitExclusions`
> +
> +`Boolean` - Default is `False`.
> +
> +By default, files in paths matched in a .gitignore file or a recognized git submodule are excluded. If this option
> +is `True`, the plugin will not attempt to recognize these files and exclude them.
> +
> +## High-Level Plugin Operation
> +
> +This plugin generates two main sets of temporary files:
> +
> +  1. A working directory in the directory `Build/{package_name}`
> +  2. For each source file with formatting errors, a sibling file with the `.uncrustify_plugin` extension
> +
> +The working directory contains temporary files unique to operation of the plugin. All of these files are removed on
> +exit of the plugin including successful or unsuccessful execution (such as a Python exception occurring). If for any
> +reason, any files in the package exist prior to running the plugin with the `.uncrustify_plugin` extension, the plugin
> +will inform the user to remove these files and exit before running Uncrustify. This is to ensure the accuracy of the

> +The plugin determines the list of relevant files to check with Uncrustify and then invokes Uncrustify with that file
> +list. For any files not compliant to the configuration file provided, Uncrustify will generate a corresponding file
> +with the `.uncrustify_plugin` extension. The plugin discovers all of these files. If any such files are present, this
> +indicates a formatting issue was found and the test is marked failed (unless `AuditOnly` mode is enabled).
> +
> +The test case log will contain a report of which files failed to format properly, allowing the user to run Uncrustify
> +against the file locally to fix the issue. If the `OutputFileDiffs` configuration option is set to `True`, the plugin
> +will output diff chunks for all code formatting issues in the test case log.

Re: [PATCH v1 1/1] .pytool/Plugin/Uncrustify: Add Uncrustify plugin

[Michael Kubacki]

I'll file a BZ and add it.

I don't see a difference comparing my template file contents against the 
corresponding files in the branch you linked. Am I missing something?

I saw the temp file directory change recently added to those plugin 
patches. My concern is that .pytool/ is tracked by git and Build/ is not.

In the unlikely case the temp file removal fails (for whatever reason), 
the git workspace does not pick up the left over files.

Given the plugin is storing temp files in a "UncrustifyPlugin" directory 
in each package's build directory, I don't anticipate conflicts (unless 
the user has intentionally tried to do so). I've also taken time to 
improve temp directory removal robustness in ways I haven't seen in 
other plugins including doing so for cases like keyboard interrupts and 
attempting multiple times for sporadic issues that might occur during 
removal (that we've very rarely observed across many CI instances).

Technically, since .pytool/ is tracked, the user could also have local 
changes there that conflict with what the plugin produces as temporary 
output.

So I didn't see a strong practical benefit to changing it from 
Build/{PackageName}/UncrustifyPlugin. Is there a benefit/issue I missed?

Thanks,
Michael

>> +
>> +`String` - Default is `"uncrustify.cfg"`

>> +When specified in the config file, this is a package relative path to the Uncrustify configuration file.

>> +## High-Level Plugin Operation
>> +
>> +This plugin generates two main sets of temporary files:
>> +
>> +  1. A working directory in the directory `Build/{package_name}`
>> +  2. For each source file with formatting errors, a sibling file with the `.uncrustify_plugin` extension
>> +
>> +The working directory contains temporary files unique to operation of the plugin. All of these files are removed on
>> +exit of the plugin including successful or unsuccessful execution (such as a Python exception occurring). If for any
>> +reason, any files in the package exist prior to running the plugin with the `.uncrustify_plugin` extension, the plugin
>> +will inform the user to remove these files and exit before running Uncrustify. This is to ensure the accuracy of the
>> +results reported from each execution instance of the plugin.
>> +
>> +The plugin determines the list of relevant files to check with Uncrustify and then invokes Uncrustify with that file
>> +list. For any files not compliant to the configuration file provided, Uncrustify will generate a corresponding file
>> +with the `.uncrustify_plugin` extension. The plugin discovers all of these files. If any such files are present, this
>> +indicates a formatting issue was found and the test is marked failed (unless `AuditOnly` mode is enabled).
>> +
>> +The test case log will contain a report of which files failed to format properly, allowing the user to run Uncrustify
>> +against the file locally to fix the issue. If the `OutputFileDiffs` configuration option is set to `True`, the plugin
>> +will output diff chunks for all code formatting issues in the test case log.

You are correct.  Please ignore.

I saw reference to Project Mu, but that is in the 
.pytool/Plugin/Uncrustify/uncrustify_ext_dep.yaml file, which is correct
because that is where the fork of uncrustify tool with EDK II extensions
is hosted.

My suggestion is to use Build/.pytool/Plugin/<PluginName> as a temp
directory that is in Build output directory that is ignored by .gitignore.

I have seen a difference between CRTL-C and CRTL-BREAK.  CRTL-C is caught
by Python exception processing so the temp dir can be removed.  CRTL-BREAK
or other OS specific actions to kill a process bypasses the Python exception
handling and the temp dir will not be removed.

I recommend moving all temp dirs/files into locations that are guaranteed
to never be seen as untracked files by git.

>>>> +By default, this plugin will discover all files in the package with the following default paths:
>>>> +
>>>> +```python
>>>> +[
>>>> +# C source
>>>> +"*.c",
>>>> +"*.h"
>>>> +]
>>>> +```
>>>> +
>>>> +From this list of files, any files ignored by Git or residing in a Git submodule will be removed. If Git is not
>>>> +found, submodules are not found, or ignored files are not found no changes are made to the list of discovered files.
>>>> +
>>>> +To control the paths checked in a given package, review the configuration options described in this file.
>>>> +
>>>> +## Configuration
>>>> +
>>>> +The plugin can be configured with a few optional configuration options.
>>>> +
>>>> +``` yaml
>>>> +  "Uncrustify": {
>>>> +      "AuditOnly": False,           # Don't fail the build if there are errors. Just log them.
>>>> +      "OutputFileDiffs": False      # Output chunks of formatting diffs in the test case log.
>>>> +                                    # This can significantly slow down the plugin on very large packages.
>>>> +      "ConfigFilePath": "",         # Custom path to an Uncrustify config file. Path is relative to the package.
>>>> +      "IgnoreStandardPaths": [],    # Standard Plugin defined paths that should be ignored.
>>>> +      "AdditionalIncludePaths": []  # Additional paths to check formatting (wildcards supported).
>>>> +  }
>>>> +```
>>>> +
>>>> +### `AdditionalIncludePaths`
>>>> +
>>>> +A package configuration file can specify any additional paths to be included with this option.
>>>> +
>>>> +At this time, it is recommended all files run against the plugin be written in the C or C++ language.
>>>> +
>>>> +### `AuditOnly`
>>>> +
>>>> +`Boolean` - Default is `False`.
>>>> +
>>>> +If `True`, run the test in an "audit only mode" which will log all errors but instead of failing the build, it will
>> set
>>>> +the test as skipped. This allows visibility into the failures without breaking the build.
>>>> +
>>>> +### `ConfigFilePath`
>>>> +
>>>> +`String` - Default is `"uncrustify.cfg"`
>>>> +
>>>> +When specified in the config file, this is a package relative path to the Uncrustify configuration file.
>>>> +
>>>> +### `IgnoreStandardPaths`
>>>> +
>>>> +This plugin by default will check the below standard paths. A package configuration file can specify any of these
>> paths
>>>> +to be ignored.
>>>> +
>>>> +```python
>>>> +[
>>>> +# C source
>>>> +"*.c",
>>>> +"*.h"
>>>> +]
>>>> +```
>>>> +
>>>> +### `OutputFileDiffs`
>>>> +
>>>> +`Boolean` - Default is `False`.
>>>> +
>>>> +If `True`, output diffs of formatting changes into the test case log. This is helpful to exactly understand what
>> changes
>>>> +need to be made to the source code in order to fix a coding standard compliance issue.
>>>> +
>>>> +Note that calculating the file diffs on a very large set of of results (e.g. >100 files) can significantly slow down
>>>> +plugin execution.
>>>> +
>>>> +### `SkipGitExclusions`
>>>> +
>>>> +`Boolean` - Default is `False`.
>>>> +
>>>> +By default, files in paths matched in a .gitignore file or a recognized git submodule are excluded. If this option
>>>> +is `True`, the plugin will not attempt to recognize these files and exclude them.
>>>> +
>>>> +## High-Level Plugin Operation
>>>> +
>>>> +This plugin generates two main sets of temporary files:
>>>> +
>>>> +  1. A working directory in the directory `Build/{package_name}`
>>>> +  2. For each source file with formatting errors, a sibling file with the `.uncrustify_plugin` extension
>>>> +
>>>> +The working directory contains temporary files unique to operation of the plugin. All of these files are removed on
>>>> +exit of the plugin including successful or unsuccessful execution (such as a Python exception occurring). If for any
>>>> +reason, any files in the package exist prior to running the plugin with the `.uncrustify_plugin` extension, the plugin
>>>> +will inform the user to remove these files and exit before running Uncrustify. This is to ensure the accuracy of the
>>>> +results reported from each execution instance of the plugin.
>>>> +
>>>> +The plugin determines the list of relevant files to check with Uncrustify and then invokes Uncrustify with that file
>>>> +list. For any files not compliant to the configuration file provided, Uncrustify will generate a corresponding file
>>>> +with the `.uncrustify_plugin` extension. The plugin discovers all of these files. If any such files are present, this
>>>> +indicates a formatting issue was found and the test is marked failed (unless `AuditOnly` mode is enabled).
>>>> +
>>>> +The test case log will contain a report of which files failed to format properly, allowing the user to run Uncrustify
>>>> +against the file locally to fix the issue. If the `OutputFileDiffs` configuration option is set to `True`, the plugin
>>>> +will output diff chunks for all code formatting issues in the test case log.
