Hi folks,
As we move towards using Git as our version control system, more services and scripts will be using identifiers instead of revisions or hashes. Already,
build.webkit.org,
results.webkit.org and
ews-build.webkit.org all display identifiers alongside revisions. Early in the transition process, we added the
git-webkit find command, which converts between hashes, revisions and identifiers. Recently, we added the
git-webkit log and
git-webkit blame commands to better support identifiers and native Git checkouts.
git-webkit log is a wrapper around git log or svn log (depending on your checkout) and annotates the output of those commands with identifiers and revisions. git-webkit log passes the arguments you provide it to your native source code management system, it’s output looks something like this:
commit 240602@main (fe5476762fc34d2a5547b7d2d8116faa7275acd7, r281148)
Date: Tue Aug 17 17:46:39 2021 +0000
[Monterey wk2 Release] performance-api/paint-timing/paint-timing-with-worker.html is a flaky crash.
...
git-webkit blame is a wrapper around git blame or svn blame (again, depending on your checkout) and also annotates the output of these commands with identifiers:
230258@main (Keith Rollin 2020-10-08 19:10:32 +0000 1) MODULES = Source Tools
184786@main (Jonathan Bedard 2017-02-02 18:42:02 +0000 2)
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 3) define build_target_for_each_module
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 4) for dir in $(MODULES); do \
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 5) ${MAKE} $@ -C $$dir PATH_FROM_ROOT=$(PATH_FROM_ROOT)/$${dir}; \
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 6) exit_status=$$?; \
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 7) [ $$exit_status -ne 0 ] && exit $$exit_status; \
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 8) done; true
229628@main (Keith Rollin 2020-09-22 18:37:51 +0000 9) endef
...
Both commands can switch the commit representation they display with the --identifier, --hash and --revision options.
Additionally, for those using Git checkouts, the conversion from Subversion revisions to Git hashes no longer requires your checkout to be configured with git-svn. Contributors may find that something like git checkout r281146 satisfies whatever need they have to interact with Subversion from Git.
All of this has been landed on trunk/main as of r280864/240404@main.
