Attached are two patches to change the Emacs repository so that the distributed
ChangeLog file is generated automatically from commit logs, instead of being
maintained manually. The first patch renames every ChangeLog file to
ChangeLog.1 (or whatever) to get it out of the way -- that is, all existing
ChangeLog files are retained in the repository as before. The second patch
arranges for the new ChangeLog file to be generated automatically from future
commit messages. The idea is that developers should continue to write commit
messages in ChangeLog style, so the automatic generation is straightforward, but
they needn't record their commit messages in ChangeLog files. This approach was
developed by Jim Meyering is used by several other GNU packages.
This is a first cut, and no doubt could be improved for Emacs, but I thought I'd
start the ball rolling by publishing something that works for me.
These patches are relative to emacs-24 commit cd2e816
<2014-11-19T19:29:40Z!eggert@cs.ucla.edu>.
PS. The first patch would be about 12 MB, so I'm attaching an abbreviated
summary of it instead of the actual patch; it can be reproduced using the
summary's recipe.

Subject: [PATCH 2/2] Generate a ChangeLog file from commit logs.
Instead of having a ChangeLog file or files in the repository,
generate the ChangeLog file automatically from the git commit logs,
as part of the process of making a distribution.
The new procedure has been tested with vc-dwim, and this
commit was generated by vc-dwim. Also, 'make dist woriks'.
However, I haven't tested other ways to create change log entries nor have
I tested the entire release process, and no doubt further work is needed.
* .gitignore: Add ChangeLog.
* Makefile.in (gen_start_date): New macro.
(gen-ChangeLog): New rule.
* admin/admin.el (make-manuals-dist--1):
Don't treat ChangeLog specially.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/notes/repo: Add note about vc-dwim.
* admin/admin.el (add-release-logs, make-manuals-dist--1):
* admin/make-tarball.txt, admin/notes/bugtracker:
* lisp/emacs-lisp/authors.el:
Add a FIXME comment.
* build-aux/gitlog-to-changelog: New file, from Gnulib.
* lisp/calendar/icalendar.el, lisp/gnus/deuglify.el:
* lisp/emacs-lisp/gulp.el, lwlib/README, make-dist:
Adjust to renamed old ChangeLog files.
* make-dist: Use 'make gen-ChangeLog' to build top-level
ChangeLog in the distribution.

+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, from which the .git/
+ directory can be derived.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
+
+3a169f4c5d9159283548178668d2fae6fced3030

What's the plan for preventing the generated ChangeLog file from
becoming too large? Currently, we roll them over to keep the file
below 1MB.
I looked at Coreutils. They started using a generated file in 2008.
Now, after 6 years, the ChangeLog is over 1MB in size. Emacs's commit
rate is about 12 times higher than that of Coreutils, so we will hit
that mark in about 6 months. What then? gitlog-to-changelog doesn't
have provisions for rolling over, and cannot be told to stop at a
given date.

gitlog-to-changelog takes the same options as `git log`
so it should be easy enough to generate logs for the
last n versions, or the last x versions in the last N years etc.
and discard anything older (which can/should be looked up in git if required).
I'm considering removing any of these old logs
from coreutils that are already in git logs:

I added an --until option to gitlog-to-changelog so that we can generate
a set of ChangeLogs rather than a single ChangeLog. We can uses this
once we want to generate multiple ChangeLogs. I'll CC: this email to
bug-gnulib since the source belongs to gnulib. Patch attached.

A 1 MB limit is too low nowadays. Other GNU Emacs source files are as
large as 6.8 MB and it's not a problem. I suggest raising the size
limit to 32 MB. The issue of size is independent of the mechanism used
to enforce it, of course.
Here's a more-radical suggestion: combine the existing ChangeLogs (there
is about 24 MB worth) into a single ChangeLog.1 file at the top level.
That would be under the 32 MB limit. Or, if we prefer a smaller limit,
16 MB say, we can create ChangeLog.1 and ChangeLog.2. This suggestion
is independent of the other suggestions.

I haven't yet looked at what Emacs has implemented now… but you may want
to take a look at Org. The ChangeLog there is generated for only the
segment of commits between releases to Emacs. If we come up with a
reliable method to (auto-)mark the latest commit that has been picked up
for the ChangeLog, then it becomes trivial to a) do the rollover, either
manually or automatically; and b) edit entries in the ChangeLog for
style or substance that have fallen behind that barrier since the
auto-generation from commit messages will not touch them.
Regards,
Achim.

I implemented this, along with some other fixes (notably, getting a proper
copyright notice into the generated ChangeLog file), and am attaching the
corresponding patches. I would like to install this into the emacs-24 branch
and then merge that into the master.
There are three patches. Patches 1 and 3 are so large that I'm just attaching
summaries here. (Patch 1 is essentially the same as before.) You can get the
full patches temporarily from here:

Subject: [PATCH 2/3] Generate a ChangeLog file from commit logs.
Instead of having a ChangeLog file or files in the repository,
generate the ChangeLog file automatically from the git commit
logs, as part of the process of making a distribution.
The new procedure has been tested with vc-dwim, and this
commit was generated by vc-dwim. Also, 'make dist woriks'.
However, I haven't tested other ways to create change log entries
nor have I tested the entire release process, and no doubt further
work is needed.
* .gitignore: Add ChangeLog.
* Makefile.in (gen_origin): New macro.
(gen-ChangeLog): New rule.
* admin/admin.el (make-manuals-dist--1):
Don't treat ChangeLog specially.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/notes/repo: Add note about vc-dwim.
* admin/admin.el (add-release-logs, make-manuals-dist--1):
* admin/make-tarball.txt, admin/notes/bugtracker:
* lisp/emacs-lisp/authors.el:
Add a FIXME comment.
* build-aux/gitlog-to-changelog: New file, from Gnulib.
* build-aux/gitlog-to-emacslog: New file.
* lisp/calendar/icalendar.el, lisp/gnus/deuglify.el:
* lisp/emacs-lisp/gulp.el, lwlib/README, make-dist:
Adjust to renamed old ChangeLog files.
* make-dist: Use 'make gen-ChangeLog' to build top-level
ChangeLog in the distribution.

Hi.
Can this generation of ChangeLog handle multiple or different authors in the ChangeLog, i.e. generate something like these:
2013-05-07 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
Jan Djärv <jan.h.d@swipnet.se>
* Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
(XINERAMA_CFLAGS): New macros.
(ALL_CFLAGS, LIBES): Use them.
How would a commit message look like to get this in the ChangeLog?
Also, how would a commit message look like if you wanted another author in the ChangeLog that is different from the one checking in? Is it enough to set Author:?
Thanks,
Jan D.

You put a Co-authored-by: line somewhere in the git commit message. E.g.:
Co-authored-by: Jan Djärv <jan.h.d@swipnet.se>
* Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
(XINERAMA_CFLAGS): New macros.
(ALL_CFLAGS, LIBES): Use them.

Why emacs-24?

Patch 3 sounds like a bad idea.
As for whether or not to go ahead: I can personally live with either
decision, tho I prefer dropping ChangeLog files from the VCS. But the
benefits are likely not high enough to justify alienating other core
maintainers, so we should only go ahead if we can get their explicit
agreement first.

Because it'd be a pain to deal with the development and master branches
using different policies for ChangeLogs. If emacs-24 stuck to the old
policy and master used the new one, not only would developers have to
remember which policy to use with which branch, the merging procedure
would be complicated by the need to merge ChangeLogs developed in the
old policy with the automatically-generated ChangeLogs of the new. There
would inevitably be hassles with dropped logs and duplicates and so
forth. We have enough problems already with the merge procedure (as far
as I can tell, it's never been done since the switch to git). So it'd be
much better to change both branches at once, assuming emacs-24 is still
active.
As a side benefit, I'm volunteering to do the first merge from emacs-24
to master, which would be useful experience for us all.

Please feel free to ask them. In the long run it'd less work for
everybody if we did the switch, and I'm volunteering to do the legwork.
A request from you would carry more weight than one from me.

I did such a merge already. There's nothing magical about it, and
whether it's done in Git or in Bzr makes no real difference (except that
we don't yet have the equivalent of bzrmerge.el which helped streamline
the process, of course).

I think this change will lower the quality of Emacs ChangeLogs, which
are important forms of documentation; and frankly I don't even see that
it will save much work. But I'm obviously in a minority, so don't let me
stop you. I do have a list though; do whatever you like in response to it.
1) There are still things to deal with from the last big change, so I'd
appreciate it if you not do this before January at the earliest.
2) Announce the change well in advance, and make it very clear what
people need to do (ie, take much more care with their logs than before).
Put a clear set of instructions in admin/notes. Eg how will I replace `C-x
4 a', `C-c C-a' now? (Frankly I expect to keep doing that, just not
commit the ChangeLog, so as I said, I can't see that this will save any
effort). I hope the answer isn't "install vc-dwim", since Emacs is
supposed to contain all the necessary VC tools itself.
3) How will I mark a change so that it does not generate a ChangeLog?
(Examples include: NEWS edits, comment fixes, fixing a paren typo in
something I committed one second earlier.) Perhaps a "#" or somesuch in
the first char of the log? How will I do this after committing if I
forgot to so mark it at the time?
4) What if I commit something, realize it was wrong, and remove it right
away? Normally I'd delete the ChangeLog entry too.
5) Will I be able to mark a portion of a log to be excluded from the
generated ChangeLog?
6) How does the correction method work (I'm being lazy and not reading
the patch). (Since notes are editable comments associated with commits,
I like the idea of using notes to correct faulty logs.) Frankly, I
expect there to be lots of mistakes, but whatever; I'm not going to
bother to correct them anymore.
7) What dates will entries get? The commit date? This may not match the
push date. What will happen with the dates of entries merged from other
branches.

With Git, it's useful to distinguish between "commit" and "push". The
former can be easily fixed, since it's still only in your local clone;
use "git amend" or even "git reset". The latter cannot be fixed,
except by running Git commands on Savannah that work directly on the
public repository, which is generally frowned upon, because others
could have pulled in-between.
> 6) How does the correction method work (I'm being lazy and not reading
> the patch).
From "gitlog-to-changelog --help:
--amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
makes a change to SHA1's commit log text or metadata.
[...]
In a FILE specified via --amend, comment lines (starting with "#") are ignored.
FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
a line) referring to a commit in the current project, and CODE refers to one
or more consecutive lines of Perl code. Pairs must be separated by one or
more blank line.
Here is sample input for use with --amend=FILE, from coreutils:
3a169f4c5d9159283548178668d2fae6fced3030
# fix typo in title:
s/all tile types/all file types/
1379ed974f1fa39b12e2ffab18b3f7a607082202
# Due to a bug in vc-dwim, I mis-attributed a patch by Paul to myself.
# Change the author to be Paul. Note the escaped "@":

For this reason and many others, I suggest blocking commits directly to
master.
Instead, people should commit to a private branch they can rewrite (git
push -f after amending a commit, for instance) and then a build system
can merge that into master when it passes ChangeLog checks (and possibly
a basic build check, and possibly maintainer approval).
This is, of course, the PR system you find on Github and such sites. It
works for thousands of projects. I see no reason why Emacs is special.

I don't think it's a serious problem. We already use "reverted last
change to <foo>" regularly.

I don't think so, but I don't see why that would be a problem.

I think by and large it doesn't: it's too complicated to be of regular use.
And since it only fixes the ChangeLog but not the "git log" output, its
usefulness is rather limited.

That's one of the work it will save us.

They'll probably gt the commit date. If you want more a more precise
explanation of what happened, you'll need to use the "git log"
output instead.

Because nobody has set such a thing up (and AFAICT Savannah doesn't
have such a thing built-in, oddly enough).

Hmm, it would require some technical work:
* targeted hydra builds for a specific branch
* a click-and-done way to merge a specific branch into master or emacs-24
* maybe a comment system
* maybe debbugs integration
* ability to review the potential ChangeLog entries that will be
generated from the commit
Is this remotely realistic?

Right. On GitHub, it's often also a decent platform for discussions.

It shouldn't be too hard, actually, to set up some code review tool,
such as Gerrit [0], Review Board [1] or Differential [2].
I think all of them support automatic merging of approved patches, or at
least make it reasonably easy. The last one seems to offer a lot of
options, at the cost of learning the whole Phabricator ecosystem.
What do you see as requirements for such a tool? Integration with
Savannah user database?
Do you like at least one of them?
I'd also welcome opinions from people who have experience working with
them, because honestly, I've only done in-browser code reviews
inside issue tracking tools, such as GitHub and GitLab.

We could add that capability to gitlog-to-changelog, if needed. It shouldn't be
hard. I'm hoping it's not needed that much.

That's correct. It's mainly intended to correct serious errors, e.g.,
misattribution. To help give a feel for it, of the 3329 commits to GNU
coreutils master since it began generating ChangeLogs automatically, only 7 have
been corrected in coreutils' build-aux/git-log-fix file.

Problem is: I'm not part of "most" because for me "PR" means "Public
Relations" (aka "BS").

I think given the current state of affair, the requirements are very
low: pretty much anything would be better than what we have now.
The only issues I can think of are that they should be installed on
machines we can control ourselves, and either they're very light on
browser resource usage or they provide some lighterweight (in terms of
resource usage) interface (such as control via email).
Being able to work with it offline is a plus.

I don't have any a-priori preference.

I suggest that Someone(TM) summarizes (on emacs-devel, I suppose) the
main features and pros/cons of using each of the alternatives, and
then we can have enough information for a decision.

Glenn is right saying that we generally don't make ChangeLog entries
for some files in etc/, notably NEWS. It's not a catastrophe, but it
would be a pity to see each change in NEWS to generate a trivial
ChangeLog entry. So if this isn't hard to add to gitlog-to-changelog,
I suggest doing that.

I don't see a problem here: the feature already exists, and its
usefulness will have to be determined by our willingness to fix the
errors.

You're right it's confusing, so let's call it a "pull request" system.
Again, my point is that nowadays this is a well-known term, not that
it's technically more correct or appropriate.
Anyhow, I've followed up in emacs-devel.

coreutils has a total of 6 people with write access, all of whom are
experienced, long-time contributors.
Emacs has nearly 200 and rising, of widely varying experience, some of
whom seem to take very little care with their commit messages.
So I don't think how things work for coreutils is likely to be
representative of how they will work for Emacs.

Yes, that's a problem. Perhaps we could have those committers work in a
separate branch, meant for more experimental changes.

Okay then. Savannah integration would be a complication for me personally.

I don't know if any of them can be considered heavy on the browser.
Phabricator seems to be the most "slick" (and probably
resource-intensive), but it also includes a powerful command-line tool,
or so they say.
Here they are live:
https://git.eclipse.org/r/

Basically, something like a layer on top of Git? That might be nice, but
probably not in the cards.

I'm going to unilaterally adopt "start those lines of the commit message
with '# '" for this.
Only 3 lines of the entire existing Emacs commit log start with '# ',
and all 3 of those lines could happily be omitted from a generated ChangeLog.
Maybe someone will add that functionality to the generate script, and
maybe they won't. I'm going to use that markup anyway.

[-- Attachment #1: Type: text/plain, Size: 420 bytes --]
Attached is a proposed announcement for installing the patch (currently it
suggests a changeover date of January 21, but obviously that's adjustable),
along with updated copies of the rename patch (which should be applied to both
emacs-24 and master branches), a followup patch for the emacs-24 branch, and a
followup patch for the master branch. This all tries to address some (though
not all) the points raised.
[-- Attachment #2: announcement.txt --]
[-- Type: text/plain, Size: 1893 bytes --]
On January 21 we plan to change the procedure for committing changes to
the Emacs git repository, so that the ChangeLog file in the Emacs
distribution is generated automatically from git commit messages,
instead of being maintained manually as a near-copy of the commit
messages.
Because the ChangeLog file will no longer be fixed up by hand after
changes are installed, it will be more important to write good commit
messages. The suggested format is:
* The first line should be a brief summary without trailing period.
* The second line should be empty.
* Any general explanatory text should come next.
* Finally, the ChangeLog entries themselves should appear, in the
format specified by the GNU coding standards.
* Append a "Fixes: bug#NNNN" line if the change fixes a bug.
Lines should hold at most 78 characters. Here is an example commit
message:
Deactivate shifted region
Do not silently extend a region that is not highlighted;
this can happen after a shift.
* lisp/window.el (handle-select-window):
* src/frame.c (Fhandle_switch_frame, Fselected_frame):
Deactivate the mark.
Fixes: bug#19003
(The actual commit message should not be indented.)
- If you use Emacs VC, one way to format ChangeLog entries is to create
a top-level ChangeLog file, and update it with 'C-x 4 a' file as
usual. Do not register the ChangeLog file under git; instead, use
'C-c C-a' to insert its contents into into your *vc-log* buffer.
- Alternatively, you can use the GNU command vc-dwim (if installed)
to maintain commit messages in ChangeLog format. When you create a
source directory FOO, run the shell command 'cd FOO;
git-changelog-symlink-init' to create a symbolic link from ChangeLog
to .git/c/ChangeLog. Edit this ChangeLog via its symlink with Emacs
commands like 'C-x 4 a', and commit the change using the shell
command 'cd FOO; vc-dwim'.

Subject: [PATCH] Generate a ChangeLog file from commit logs
Instead of having a ChangeLog file or files in the repository,
generate the ChangeLog file automatically from the git commit logs,

* .gitignore: Add ChangeLog.
* Makefile.in (gen_origin): New macro.
(gen-ChangeLog): New rule.
* admin/admin.el (make-manuals-dist--1):
Don't treat ChangeLog specially.
* admin/make-tarball.txt, admin/notes/bugtracker:
* lisp/emacs-lisp/authors.el:
Add a FIXME comment.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/notes/repo: Add note about vc-dwim.
* admin/admin.el (add-release-logs, make-manuals-dist--1):
* build-aux/gitlog-to-changelog: New file, from Gnulib.
* build-aux/gitlog-to-emacslog: New file.
* lisp/calendar/icalendar.el, lisp/gnus/deuglify.el:
* lisp/emacs-lisp/gulp.el, lwlib/README, make-dist:
Adjust to renamed old ChangeLog files.
* build-aux/git-hooks/pre-commit: Disallow ChangeLog commits.
* etc/CONTRIBUTE: Adjust suggested procedures accordingly.
* make-dist: Use 'make gen-ChangeLog' to build top-level
ChangeLog in the distribution. Distribute gitlog-to-changelog.

+
+Convert git log output to ChangeLog format. If present, any ARGS

+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, from which the .git/
+ directory can be derived.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --until=DATE convert only the logs older than DATE.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:

Subject: [PATCH] Generate a ChangeLog file from commit logs
Instead of having a ChangeLog file or files in the repository,
generate the ChangeLog file automatically from the git commit logs,
as part of the process of making a distribution.
* .gitignore: Add ChangeLog.
* CONTRIBUTE: Adjust suggested procedures accordingly.
* Makefile.in (gen_origin): New macro.
(gen-ChangeLog): New rule.
* admin/admin.el (make-manuals-dist--1):
Don't treat ChangeLog specially.
* admin/make-tarball.txt, admin/notes/bugtracker, admin/notes/repo:
* lisp/emacs-lisp/authors.el:
Add a FIXME comment.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/admin.el (add-release-logs, make-manuals-dist--1):
* build-aux/git-hooks/pre-commit: Disallow ChangeLog commits.
* build-aux/gitlog-to-changelog: New file, from Gnulib.
* build-aux/gitlog-to-emacslog: New file.
* lisp/calendar/icalendar.el, lisp/gnus/deuglify.el:
* lisp/emacs-lisp/gulp.el, lwlib/README, make-dist:
Adjust to renamed old ChangeLog files.
* make-dist: Use 'make gen-ChangeLog' to build top-level
ChangeLog in the distribution. Distribute gitlog-to-changelog.
Fixes: bug#19113

+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, from which the .git/
+ directory can be derived.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --until=DATE convert only the logs older than DATE.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:

I would like to see people get at least one week's notice, since this
changes a decades-old convention. This bug report doesn't count as
notice. So Jan 21 is almost too soon...
To avoid confusion, does emacs-24 need to merged to trunk just before
this change?
(I would also like to repeat my request for a dedicated announcement
mechanism for things like this. But you don't need to wait for such a
mechanism to exist before making this change.

Yes, I'll change the date to give people a week at least.

I was planning to do a merge, yes. My thought was to install the changes in
emacs-24 and then skip them when merging to master, as there's a separate set of
changes prepared for master.

Could we simply only make the change on master, and keep using the
ChangeLog files in `emacs-24'?
This would decouple this change from the schedule of the Emacs-24.5
release, which I think would be good. Then we could make the change on
Valentine's day.

Not easily, I'm afraid, as the emacs-24 branch would contain patches to
ChangeLog files, and these files should be absent on the master branch.
This would make merges problematic.

Sounds less risky than testing the new changelog-free release process on
a release which i supposed to be short, tho. Spurious conflicts are
part of life, to some extent.

OK, I'll give that a try in my private copy and see how well it works out.
There's another thing that I would like to get working better too, namely,
rotation of commit messages into ChangeLog.1 etc. files. So that's two birds
that perhaps I can kill with 1.5 stones.

[-- Attachment #1: Type: text/plain, Size: 939 bytes --]
I hacked on this a bit and came up with the attached files, which should be
improvements. 'announcement.txt' is a draft email to be sent to emacs-devel
about a week before the change. The two patch files have the same role as
before, and attempt to address the comments made in this thread.
It's now much easier to edit ChangeLog history: run 'make change-history' to
prepend newer commit messages to the file ChangeLog.1 (thus marking them as
older), edit ChangeLog.1 by hand, and then commit the result. Once ChangeLog.1
gets too big it should be easy to start working on ChangeLog.2.
I had trouble implementing Glenn's suggestion of using a '#' prefix to mark
ignorable commit messages, as Git typically uses '#' for its own purposes when
editing commit messages. I changed the prefix to '; ' and this worked better,
so I went with that. It should be easy to use any string that starts with a
character other than '#'.
[-- Attachment #2: announcement.txt --]
[-- Type: text/plain, Size: 2941 bytes --]
On [fill in the date here -- about a week from when this
announcement is made] we plan to change the procedure for
committing changes to the Emacs git repository, so that the
ChangeLog file in the Emacs distribution can be generated
automatically from git commit messages. Although you'll still be
able to edit ChangeLog history by running 'make change-history'
and then committing changes to a new top-level file (initially
'ChangeLog.1'), most commits shouldn't need to change any
ChangeLog* files and this should simplify merging.
The suggested format for commit messages will be changed slightly:
- File names should be relative to the top level, e.g.:
Deactivate shifted region
Do not silently extend an unhighlighted region;
this can happen after a shift.
* doc/emacs/mark.texi (Shift Selection): Document this.
* lisp/window.el (handle-select-window):
* src/frame.c (Fhandle_switch_frame, Fselected_frame):
Deactivate the mark.
Fixes: bug#19003
(The actual commit message should not be indented.)
- If the commit has authors other than yourself, the commit
message should contain a separate line like the following:
Co-authored-by: Joe Schmoe <j.schmoe@example.org>
- If the commit is a tiny change that is exempt from copyright
paperwork, the commit message should contain a separate line
like the following:
Copyright-paperwork-exempt: yes
- If the commit message should not appear in generated
ChangeLogs, its first line should start with "; ".
With the new approach there are multiple ways to format ChangeLog
entries as part of the process of creating a commit message:
- If you use Emacs VC, you can create a top-level ChangeLog file,
and update it with 'C-x 4 a' file as usual. Do not register
the ChangeLog file under git; instead, use 'C-c C-a' to insert
its contents into into your *vc-log* buffer.
- Alternatively, you can use the vc-dwim command to maintain
commit messages. When you create a source directory, run the
shell command 'git-changelog-symlink-init' to create a symbolic
link from ChangeLog to .git/c/ChangeLog. Edit this ChangeLog
via its symlink with Emacs commands like 'C-x 4 a', and commit
the change using the shell command 'vc-dwim --commit'. Type
'vc-dwim --help' for more.
The above will all be documented in the files CONTRIBUTE (for
ordinary commits) and admin/notes/repo (for commits that edit
ChangeLog history files).
This change will be installed on the master branch. Other
branches can adopt this change whenever convenient. The emacs-24
branch can continue to use the old procedure, and changes to
ChangeLog files in emacs-24 can be discarded by hand when merging
to master.
Although this new style of maintenance is common in other GNU
projects, Emacs has its own special needs and most likely there
will be glitches after the transition. We will do our best to
straighten out these problems as they occur.

(change-history-commit): New rules.
* admin/admin.el (make-manuals-dist--1):
Don't worry about doc/ChangeLog.
* admin/authors.el: Add a FIXME.
* admin/make-tarball.txt:
* lisp/calendar/icalendar.el:
* lisp/gnus/deuglify.el:
* lisp/obsolete/gulp.el:
* lwlib/README:
Adjust to renamed ChangeLog history files.
* admin/merge-gnulib (GNULIB_MODULES): Add gitlog-to-changelog.
* admin/notes/repo: Call it 'master' a la Git, not 'trunk' a la Bzr.
Remove obsolete discussion of merging ChangeLog files.
New section "Maintaining ChangeLog history".
* build-aux/git-hooks/pre-commit:
Reject attempts to commit files named 'ChangeLog'.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* make-dist: Make and distribute top-level ChangeLog if there's a
.git directory. Distribute the new ChangeLog history files
instead of scattered ChangeLog files. Distribute the new files
gitlog-to-changelog and gitlog-to-emacslog.

+
+Convert git log output to ChangeLog format. If present, any ARGS

+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --srcdir=DIR the root of the source tree, from which the .git/
+ directory can be derived.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --until=DATE convert only the logs older than DATE.
+ --ignore-matching=PAT ignore commit messages whose first lines match PAT.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+ --strip-tab remove one additional leading TAB from commit message lines.
+ --strip-cherry-pick remove data inserted by "git cherry-pick";
+ this includes the "cherry picked from commit ..." line,
+ and the possible final "Conflicts:" paragraph.
+ --help display this help and exit

+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.

I think we wanted to stop using ChangeLog files on the branch as well,
and that is the only reason we are waiting until after 24.5 release.

No, we instead decided we didn't want to wait.

OK, it's April 7 by my clock, so I've installed the patch, with a few minor
fixups (mostly having to do with allowing top-level history files ChangeLog.2,
ChangeLog.3, etc., in the future). I'm marking this bug as done. No doubt
there will be glitches in the fix, but they can be followed up with further bug
reports.
