Yeah, I think that is sensible.
I am meaning to merge your retire-fnmatch topic to 'master'. What
should the Release Notes say for the upcoming release?
You can build with USE_WILDMATCH=YesPlease to use a replacement
implementation of pattern matching logic used for pathname-like
things, e.g. refnames and paths in the repository. The new
implementation is not expected change the existing behaviour of
Git at all, except for "git for-each-ref" where you can now say
"refs/**/master" and match with both refs/heads/master and
refs/remotes/origin/master. In future versions of Git, we plan
to use this new implementation in wider places (e.g. "git log
'**/t*.sh'" may find commits that touch a shell script whose
name begins with "t" at any level), but we are not there yet.
By building with USE_WILDMATCH, using the resulting Git daily
and reporting when you find breakages, you can help us get
closer to that goal.

* [PATCH] mergetool: clean up temp files when aborted
From: Phil Hord @ 2013-01-24 18:23 UTC (permalink / raw)
To: git; +Cc: phil.hord, Theodore Ts'o, Junio C Hamano, Phil Hord
When handling a symlink conflict or a deleted-file conflict, mergetool
stops to ask the user what to do. If the user chooses any option besides
"(a)bort", then the temporary files which mergetool created in
preparation for handling the conflict are removed. But these temporary
files are not removed when the user chooses to abort the operation.
$ git cherry-pick other/branch
error: could not apply 4e43581... Fix foo.c
$ git status --short
DU foo.c
$ git mergetool
Merging:
foo.c
Deleted merge conflict for 'foo.c':
{local}: deleted
{remote}: modified file
Use (m)odified or (d)eleted file, or (a)bort? a
Continue merging other unresolved paths (y/n) ? n
$ git status --short

?? foo.c.BACKUP.16929.c
?? foo.c.BASE.16929.c
?? foo.c.LOCAL.16929.c
?? foo.c.REMOTE.16929.c
These temporary files should not remain after the mergetool operation is
completed.
Remove the temporary files by calling the cleanup_temp_files when the
user chooses to abort the mergetool operation.
It looks like 'cleanup_temp_files' without the --save-backups option is
the correct thing to do, and this is how this commit is implemented. But
some other paths do use --save-backups resulting in a foo.c.orig file
being left behind. That seems to be a different bug, though.

Please repost the patch (with possible updates) for review when
attempting to resurrect an ancient topic, instead of forcing people
to hunt for an ancient message.
I think your patch is wrong. What happens when we see a Subject:

before your new code has a chance to see Content-Type: header?

I think the check you want to add is to the cache-tree code; before
writing the new index out, if you suspect you might have called
cache_tree_update() before, invalidate any hierarchy that is
recorded to produce a tree object that refers to an object that is
only available through external object store.
As to the logic to check if a object is something that we should
refuse to create a new dependent, I think you should not butcher
sha1_object_info_extended(), and instead add a new call that checks
if a given SHA-1 yields an object if you ignore alternate object
databases that are marked as "external", whose signature may
resemble:
int has_sha1_file_proper(const unsigned char *sha1);
or something.
This is a tangent, but in addition, you may want to add an even
narrower variant that checks the same but ignoring _all_ alternate
object databases, "external" or not:
int has_sha1_file_local(const unsigned char *sha1);
That may be useful if we want to later make the alternate safer to
use; instead of letting the codepath to create an object ask
has_sha1_file() to see if it already exists and refrain from writing
a new copy, we switch to ask has_sha1_file_locally() and even if an
alternate object database we borrow from has it, we keep our own
copy in our repository.
Not tested beyond syntax, but rebasing something like this patch on
top of your "mark external sources" change may take us closer to
that.

* [PATCH] git-cvsimport.txt: cvsps-2 is deprecated
From: John Keeping @ 2013-01-24 19:18 UTC (permalink / raw)
To: Junio C Hamano; +Cc: git, Eric S. Raymond, Chris Rorvick
In-Reply-To: <7vip6ndveb.fsf@alter.siamese.dyndns.org>
git-cvsimport relies on version 2 of cvsps and does not work with the
new version 3. Since cvsps 3.x does not currently work as well as
version 2 for incremental import, document this fact.
Specifically, there is no way to make new git-cvsimport that supports
cvsps 3.x and have a seamless transition for existing users since cvsps
3.x needs a time from which to continue importing and git-cvsimport does
not save the time of the last import or import into a specific namespace
so there is no safe way to calculate the time of the last import.

Wouldn't it make more sense in such a situation if your users can
keep using the old "tortoisemerge" configured in their configuration
and when the renamed one is found the mergetool automatically used
it, rather than the way your patch is done? It seems that you are
forcing all the users to reconfigure or retrain their fingers. Is
that the best we can do? Is it too cumbersome to autodetect the
presense of tortoisegitmerge and redirect a request for tortoisemerge
to it, perhaps using translate_merge_tool_path (cf. mergetools/bc3)?
Assuming that people that have both variants will always want
mergetool to use tortoisegitmerge, that is. If there are some
features missing from or extra bugs in tortoisegitmerge that makes
some people favor tortoisemerge, then giving two choices like your
patch does may make more sense. I only know the difference between
the two from your four-line description above, but it does not look
like it is the case.

So in short, two tortoises and kompare are only valid as mergetool
but cannot be used as difftool? No, I am reading it wrong.
merge.tool can be used for both, kompare can be used as difftool,
and two tortoises can only be used as mergetool.
This paragraph needs to be rewritten to unconfuse readers. The
original is barely intelligible, and it becomes unreadable as the
set of tools subtracted by "minus" and added by "plus" grows.

Aren't there cases where people "abort" so that they can have a
chance inspect them outside mergetool program? If there are no such
cases, then I would agree with your claim "should not remain", but
the proposed log message does not explay why it is sure that there
are no such use cases.

* [PATCH 0/4] Fix "git difftool --tool-help"
From: John Keeping @ 2013-01-24 19:55 UTC (permalink / raw)
To: git; +Cc: David Aguilar
The "--tool-help" option to git-difftool currently displays incorrect
output since it uses the names of the files in
"$GIT_EXEC_PATH/mergetools/" rather than the list of command names in
git-mergetool--lib.
This series fixes this by changing it to simply delegate to a function
in git-mergetool--lib.
The first three patches are just refactorings to move the show_tool_help
function from git-mergetool to git-mergetool--lib and make it usable by
git-difftool. The final patch switches git-difftool to use this
function.
John Keeping (4):
git-mergetool: move show_tool_help to mergetool--lib
git-mergetool: remove redundant assignment
git-mergetool: don't hardcode 'mergetool' in show_tool_help
git-difftool: use git-mergetool--lib for "--tool-help"

* [PATCH 2/4] git-mergetool: remove redundant assignment
From: John Keeping @ 2013-01-24 19:55 UTC (permalink / raw)
To: git; +Cc: David Aguilar
In-Reply-To: <cover.1359057056.git.john@keeping.me.uk>
TOOL_MODE is set at the top of git-mergetool.sh so there is no need to
set it again in show_tool_help. Removing this lets us re-use
show_tool_help in git-difftool.

When using show_tool_help from git-difftool we will want it to print
"git difftool" not "git mergetool" so use "git ${TOOL_MODE}tool".

* [PATCH 4/4] git-difftool: use git-mergetool--lib for "--tool-help"
From: John Keeping @ 2013-01-24 19:55 UTC (permalink / raw)
To: git; +Cc: David Aguilar
In-Reply-To: <cover.1359057056.git.john@keeping.me.uk>
The "--tool-help" option to git-difftool currently displays incorrect
output since it uses the names of the files in
"$GIT_EXEC_PATH/mergetools/" rather than the list of command names in
git-mergetool--lib.
Fix this by simply delegating the "--tool-help" argument to the
show_tool_help function in git-mergetool--lib.

Isn't the whole "and git-cvsimport does not save the time..." part
something that can be fixed in the new cvsimport that reads the
output from cvsps3?
To me, it sounds more like
cvsps2 + cvsimport has an unfixable bugs and there have been an
effort to rewrite cvsps2 from scratch. The resulting cvsp3
currently is unusable with cvsimport, especially when importing
the history incrementally, and it isn't expected that it will
ever be usable with cvsimport again.
There are other tools that analyse the original history better
and emits more correct output when used to convert the whole
history, and hopefully cvsps3 + fast-import would become one of
them. Suggest users to use them instead of cvsimport when they
are not doing an incremental import.
By the way, do we want to make any recommendation to the distro
folks which cvsps they should ship? It appears that not shipping
cvsps2 would be a major regression if cvsps3 does not plan to
support incrementals, so shipping both might be the safest way for
them to support their users with different needs.
Thanks. I think the patch text itself is good.

Yes it can be fixed there (and I have patches to do that) - my argument
here is that there cannot be a seamless upgrade for people who are
currently using git-cvsimport incrementally. If you don't have that
file then how do you create it to reflect the current state of your
repository?

cvsps3 isn't a re-write, it's cvsps2 with a lot of things ripped out and
a fast-export mode added. And in fast-export mode it cannot inspect the
Git repository in the same way that git-cvsimport does.

Yes. The consensus seems to be that cvs2git is the most correct.

I agree. cvsps is only one binary and a man page so I don't think it
would be too hard to ship both.

This is inherited from the original, but these days we try to avoid
touch, unless it is about setting a new file timestamp. The
canonical (in the script we write) way to create an empty file is:
: >foo
with or without ": ", it does not matter that much.

Why do we want "whatever_7" variables and use "cut -c1-7" to produce
them? Is "7" something we care deeply about?
I think what we care a lot more than "7" that happens to be the
current default value is to make sure that, if we ever update the
default abbreviation length to a larger value, the abbreviation
shown with --format=%h is consistent with the abbreviation that is
given by rev-parse --short.
head1_short=$(git rev-parse --short $head1)
perhaps?

Do not use "cat-file -p" that is for human consumption in scripts,
unless you are testing how the format for human consumption should
look like (we may later add more pretty-print to them), which is not
the case here.
Also be careful and pay attention to the end of the header; you do
not want to pick up a random "parent" string in the middle of a log
message.
head2_parent=$(git cat-file commit HEAD | sed -n -e "s/^parent //p" -e "/^$/q")
would be much better.

Does this patch make the all tests in this script fail for people
without cp1251 locale installed? We already have tests that depend
on 8859-1 and some other locales, and we'd be better off limiting
such dependency to the minimum.
Same comment applies to the changes to other test scripts.
Thanks.

I am not disagreeing with your patch text to warn the current users
that cvsimport will be made unusable if they lose cvsps2, and they
are better off using other tools when doing a whole-history import.
I was trying to make sure that my understanding of the current
situation and future possibilities matches yours.
Thanks, I think you clarified the situation better with your
response.

What is going on here?
Is this an example that shows that i18n.commitencoding works
correctly with iso8859-1 but not with cp1251?

This and remaining hunks to this script shows that it would be
helped by the same love you gave to other scripts with your first
two patches before you add the "non-unicode" tests, no?

Indeed, that description matches what I see. The other segfault seems to be in the same place too.
The segfault hits with the following stack (optimization off):
0 git-log parse_commit_header + 39 (pretty.c:738)
1 git-log format_commit_one + 3102 (pretty.c:1138)
2 git-log format_commit_item + 177 (pretty.c:1203)
3 git-log strbuf_expand + 172 (strbuf.c:247)
4 git-log format_commit_message + 196 (pretty.c:1263)
5 git-log notes_cache_match_validity + 215 (notes-cache.c:22)
6 git-log notes_cache_init + 212 (notes-cache.c:41)
7 git-log userdiff_get_textconv + 176 (userdiff.c:301)
8 git-log get_textconv + 66 (diff.c:2233)
9 git-log has_changes + 53 (diffcore-pickaxe.c:205)

commit->message was freed and nulled earlier in a call to cmd_log_walk. This test reproduces it reliably on my machine:

You may be right about other people's workflows which I forgot to
consider. I have noticed a lot of inconsistency in this tool wrt to
mergetool.keepBackup and mergetool.keepTemporaries. Perhaps this
change should hinge on the latter.
Would you agree with this rephrased statement (accompanied by matching logic)?
When mergetool.keepTemporaries is false or not set, these temporary files
should not remain when the mergetool operation is aborted.
Here is the wording from git help config:
mergetool.keepBackup
After performing a merge, the original file with conflict
markers can be saved as a file with a .orig extension. If this
variable is set to false then this file
is not preserved. Defaults to true (i.e. keep the backup files).
mergetool.keepTemporaries
When invoking a custom merge tool, git uses a set of
temporary files to pass to the tool. If the tool returns an error and
this variable is set to true, then
these temporary files will be preserved, otherwise they
will be removed after the tool has exited. Defaults to false.
I have another commit in the works to clean up consistency around the
keepBackup. I'll re-roll this one at the same time.
Phil
