Hello,
Thank you for your patience during this extended hard freeze.
Just one more step to go. There has been a delay in the review of
the patch series with the uncrustify source changes. PR(6). This
patch series was not sent out as patch review email because of its
very large size. It only contains source style changes and the
CompareBuild tool and GitHub action has shown there are no binary
differences introduced with these source style changes.
If you are a package maintainer, then please review the following
branch/PR for your package contents and review the EDK II CI results
and BuildCompare results. I do not expect a line by line review
because we already had time to provide feedback on the source style
performed by uncrustify. Instead, a Reviewed-by for your package
indicates that you have reviewed the EDK II CI results and CompareBuild
tool functionality and results and you accept the source style
changes to your package.

Changes from Update #3
----------------------------------------------------------------------------
* Pushed PR (5)
* Added link to PR(6). EDK II CI Status is PASS. Build Compare PASS.
* Waiting for review of PR (6)
* Review of PR (7) completed and waiting for review of PR (6)
----------------------------------------------------------------------------
Changes from Update #2
----------------------------------------------------------------------------
* Changed order of PRs swapping (4) and (5). The PR that activates
increases the max CI agent job time is independent of all the other
PRs and its review is complete, so it can be committed now.
* Pushed PRs (1), (2), (3), (4).
* Waiting for review to complete for PRs (5) and (6)
* Reviews complete for PR (7)
* Identifies steps using git filter-branch to apply uncrustify changes to a
code review patch series that was generated before the uncrustify changes
avoiding manual merge.
* Identified steps using git filter-repo to generate an alternate history of
the edk2 repo with uncrustify changes applied on every commit. This may
be useful when evaluating changes to files using tools like git blame
without the large uncrustify patch series.
---------------------------------------------------------------------------
Changes from Update #1
----------------------------------------------------------------------------
* Changed order of PRs swapping (6) and (7). The PR that activates
EDK II CI check UncrustifyCheck has to be last because it unconditionally
checks all C/H files in all packages. Not just files that have been
modified like some of the other checkers.
* Updated link to the branch with the UncrustifyCheck plugin that has been
updated with a one line change and Reviewed-by and Tested-by tags.
https://github.com/mdkinney/edk2/tree/Bug_3748_add_uncrustify_ci_plugin_v6
* Reviews complete for (1), (2), (3), (5), and (7)
---------------------------------------------------------------------------
Michael Kubacki and I have prepared the patches required to apply the
uncrustify changes and enable EDK II CI to check all submitted
patches have been run through uncrustify.
We have verified through the CompareBuild GitHub Action that the
format changes performed by uncrustify have no functional changes.
All of the OBJ, LIB, DLL, EFI, FFS, FV, and FD files match 100%
across 70 VS2019/GCC5 builds of all package/platform DSC files in
the edk2 repo.
The hard freeze will be extended after the edk2-stable202111 tag until
all uncrustify related changes are committed. We do not expect this
to take more than a few days. Do not push any PRs until the hard
freeze is lifted.
The changes are broken up into 7 patch series/PRs. The PRs are ordered
so they can be submitted using the normal submission process and EDK II
CI will pass for each one. Details are listed below.
Uncrustify 73.0.3 for EDK II
=============================
* Sources: https://dev.azure.com/projectmu/_git/Uncrustify
* Documentation: https://dev.azure.com/projectmu/Uncrustify/_wiki/wikis/Uncrustify.wiki/1/Project-Mu-(EDK-II)-Fork-Readme
* Download: https://dev.azure.com/projectmu/Uncrustify/_packaging?_a=package&feed=mu_uncrustify&package=mu-uncrustify-release&protocolType=NuGet&version=73.0.3
Installing Uncrustify
======================
The Uncrustify tool is installed automatically when the Pytools
environment is used and the stuart* commands are run to complete the
environment setup. Please see:
https://github.com/tianocore/edk2/tree/master/.pytool#running-ci-locally
Uncrustify can also be installed from the download page listed above
or built from sources from the source link above.
The Documentation link provides instruction on how to run uncrustify from
the command line or install as a Visual Studio Code plugin. The main
uncrustify documentation also describes how to integrate with a few other
editors.
We have also discussed a client side githook. That effort has not started.
Let us know if that is a feature you would find useful.
Developer impact for new code reviews
======================================
Once the uncrustify checker is active in EDK II CI, developers must
make sure their patches are run through the uncrustify tool before
sending the patches for review.
Developers must install and run uncrustify against changes files before
sending patch review emails or submitting PR for EDK II CI. If EDK II CI
detects and differences in source formatting, then EDK II CI will fail
and the developer must run uncrustify and resubmit the patches.
Developer impact to patch series/PRs reviewed during edk2-stable201121 soft/hard freeze
=======================================================================================
Developers must rebase their changes after the uncrustify source changes are
committed. The branch with a preview of the uncrustify changes can be used
to start this rebase work.
https://github.com/mdkinney/edk2/tree/Bug_3737_3739_ApplyUncrustifyChanges_V5
The following steps can be used to update an existing branch with the
required uncrustify format. This is the Windows version. I will add
the Linux version soon.
1) Fetch and checkout and rebase to latest edk2/master
git fetch origin
git checkout master
git rebase origin/master
2) Make a backup copy of plugin UncrustifyCheck outside WORKSPACE.
(e.g. C:\Temp\UncrustifyCheck) so the uncrustify tool executable and
EDK II specific uncrustify configuration file available when working
with a branch that does not have those tools in its scope.
xcopy .pytool\Plugin\UncrustifyCheck C:\Temp\UncrustifyCheck
3) Check out the patch series branch (e.g. MyBranch)
git checkout MyBranch
4) Rebase patch series against edk2-stable202111
git rebase edk2-stable202111
5) Create new branch for the uncrustifed version (e.g. MyBranch_Uncrustified)
git checkout -b MyBranch_Uncrustified
6) Use git filter-branch to uncrustify all the commits in the series
between the rebase target from (2) and HEAD of the branch. A filter
can be used to scope the uncrustify operations to only the C/H files
in the specific package the patch series is against. (e.g. DynamicTablesPkg).
BaseTools should always be excluded. If the package scoped filter is
not used, it will still work, but will take longer to run because
uncrustify will rescan every C/H files in the whole repo.
git filter-branch --tree-filter "git ls-files DynamicTablesPkg*.c DynamicTablesPkg*.h :!BaseTools/* | c:\\Temp\\UncrustifyCheck\\mu-uncrustify-release_extdep\\Windows-x86\\uncrustify.exe -c c:\\Temp\\UncrustifyCheck\\uncrustify.cfg -F - --replace --no-backup --if-changed" edk2-stable202111..HEAD
7) Now that all the individual patches in the branch are uncrustified,
rebase against latest edk2/master that is already uncrustified.
git rebase master
8) Verify the patches in this new branch.
Impacts to tracing history across the uncrusity changes
=======================================================
Tools the view file and line history do work with the large uncrustify
patch series. One impact is that the operations can be very slow due
to the large uncrustify patches.
One option to provide a faster experience is to provide an alternate
version of the edk2 repository as "documentation" that has the
entire history re-written with uncrustify run on every commit.
The tool called git-filter-repo can be used to perform this
transformation and runs in a reasonable period of time (a few hours)
https://github.com/newren/git-filter-repo
https://github.com/newren/git-filter-repo/blob/main/contrib/filter-repo-demos/lint-history
The following steps can be used to perform this transformation.
This is the Windows version. I will add the Linux version soon.
** WARNING ** This operation modifies(rewrites) all the commits
in the local copy of the repo. Do not perform
these steps on a local repo you are using for
active development.
1) Clone edk2 into a new directory (see **WARNING**)
git clone https://github.com/tianocore/edk2.git edk2-uncrustified
cd edk2-uncrustified
2) Setup python virtual env, install pytools, and run stuart commands
to setup build environment which includes installing uncrustify tools.
https://github.com/tianocore/edk2/tree/master/.pytool#running-ci-locally
3) Make a backup copy of plugin UncrustifyCheck outside WORKSPACE.
(e.g. C:\Temp\UncrustifyCheck) so the uncrustify tool executable and
EDK II specific uncrustify configuration file available when working
with a branch that does not have those tools in its scope.
xcopy .pytool\Plugin\UncrustifyCheck C:\Temp\UncrustifyCheck
4) Use lint-history.py from git-filter-repo examples
https://github.com/newren/git-filter-repo
https://github.com/newren/git-filter-repo/blob/main/contrib/filter-repo-demos/lint-history
Line #127 - Add try except around subprocess.check_call() with except
being pass. This is required because there are a few commits of C
files in the edk2 repo that have incorrect C syntax and do not
build with a C compiler and break the uncrustify parser. Skip reformat
of C files that can not be parsed by uncrustify. These rare instances
are addressed in the commit that fixes the C syntax error.
Run this slightly modified version of lint-history. Include only
C/H files and exclude directories that start with 'Tools' or 'BaseTools'.
This step took about 2.2 hours on a laptop.
lint-history.py
--relevant "return (not filename.startswith(b'Tools') and not filename.startswith(b'BaseTools') and (filename.endswith(b'.c') or filename.endswith(b'.h')))"
c:\\work\\GitHub\\tianocore\\foo\\UncrustifyCheck\\mu-uncrustify-release_extdep\\Windows-x86\\uncrustify.exe -c c:\\work\\GitHub\\tianocore\\foo\\UncrustifyCheck\\uncrustify.cfg --replace --no-backup --if-changed
