Agree, and other reasons such as grepping the source tree. I see some
advantages to having ChangeLog files separate from git's knowledge,
and I don't really see any disadvantages (perhaps a small amount of
lost time, but I think that will be negligible once we have proper
tools and procedures).
IMO ChangeLog entries (in whatever format) should be automatically
generated for each git commit from the message (which should include
the PR #), author info, commit (push) date, and the set of files that
are modified, added, or removed. Maintaining the ChangeLog
automatically and incrementally as a text file will make it easy to
fix erroneous entries manually, though ideally those are rare.
Are there good arguments against automatically generated entries? Ralf
identified the following:
* how you want to _replace_ bogus changelog entries,
-- Do it manually. Easy if ChangeLogs are generated incrementally.
Educate developers so they don't push commits that cause bogus
entries. Use a back-end tool (see below) to avoid human error.
* how you want to cope handle rtems CVS history.
-- Unnecessary if ChangeLog is maintained automatically and
incrementally from git commit metadata.
* how you want to handle changelogs of commits the git-commiter
received from somebody else.
-- Use the --author flag of git. git commit --author="Some User
<someuser at domain>"
In order to make this work I think we should integrate ChangeLog entry
generation together with BuildBot or some similar back-end script that
parses a git push to append ChangeLog entries into the repository
