I found this during a conflict merge testing. The original did
not have either DF (a file) or DF/DF (a file DF/DF under a
directory DF). One side created DF, the other created DF/DF. I
first resolved DF as a new file by taking what the first side
did. After that, the entry DF/DF cannot be resolved by running
git-update-cache --remove although it does not exist on the
filesystem.
$ /bin/ls -F
AN DF MN NM NN SS Z/
$ git-ls-files --stage | grep DF
100644 71420ab81e254145d26d6fc0cddee64c1acd4787 0 DF
100644 68a6d8b91da11045cf4aa3a5ab9f2a781c701249 2 DF/DF
$ git-update-cache --remove DF/DF
fatal: Unable to add DF/DF to database
It turns out that the errno from open() in this case was not
ENOENT but ENOTDIR, which the code did not check. Here is a
fix.

The merge-cache program was updated to pass executable bits when
calling git-merge-one-file-script, but the called script
supplied as an example were not using them carefully.
This patch fixes the following problems in the script:
* When a new file is created in a directory, which is a file in
the work tree, it tried to create leading directory but did
not check for failure from the "mkdir -p" command.
* The script did not check the exit status from the
git-update-cache command at all.
* The parameter "$4" to the script is a file name that can
contain almost any characters, so it must be quoted with
double quotes and also needs to be preceded with -- to mark
it as a non-option when passed to certain commands.
* The chmod command was used with parameter "$6" or "$7" to set
the mode bits. This contradicts with the strategy taken by
checkout-cache, where we honor user's umask and force only
the executable bits. With this patch, it creates a new file
by redirecting into it (thus honoring user's default umask),
and then uses "chmod +x" if we want the resulting file
executable. Without this fix, the merge result becomes 0644
or 0755 for users whose umask is 002 for whom it should
become 0664 or 0775.
* When "$1 -> $2 -> $3" case was not handled, the script did
not say which path it was working on, which was not so useful
when used with the -a option of git-merge-cache.

I said:
- Stop attempting to be compatible with cg-patch, and drop
(mode:XXXXXX) bits from the diff.
- Do keep the /dev/null change for created and deleted case.
- No "Index:" line, no "Mode change:" line, anywhere in the
output. Anything that wants the mode bits and sha1 hash can
do things from GIT_EXTERNAL_DIFF mechanism. Maybe document
suggested usage better.
This adds an example script git-apply-patch-script, that can be
used as the GIT_EXTERNAL_DIFF to apply changes between two trees
directly on the current work tree, like this:
GIT_EXTERNAL_DIFF=git-apply-patch-script git-diff-tree -p <tree> <tree>

We used to have all these time-related issues, long gone now.

We'd get the sign wrong for the minutes part of a negative offset.

Also, add EEST (hey, it's Finland).

This still doesn't actually really _use_ it properly, nor make any

we wanted to) fake it a bit better.
Right now the code actually still says "it's always summer". I'm

This date parser turns line-noise into a date. Cool.

...since everything out there is either strange (libc mktime has issues
with timezones) or introduces unnecessary dependencies for people (libcurl).
This goes back to the old date parsing, but moves it out into a file of
its own, and does the "struct tm" to "seconds since epoch" handling by
hand.
I grepped through the tz-database and it seems there's one "country"
left that has non-60-minute DST: Lord Howe Island. All others dropped
that before 1970.
|
|
This switches git-commit-tree to using curl_getdate() for the
AUTHOR_DATE, and thus fixes the problem with "mktime()" parsing dates in
the local timezone. It also ends up being more permissive about the
format of the date.

This also regularizes the make. The source files themselves don't get
the "git-" prefix, because that's just inconvenient. So instead we just
make the rule that "git-xxxx" depends on "xxxx.c", and do that for
all the core programs (ie the old "git-mktag.c" got renamed to just
"mktag.c" to match everything else).
And "show-diff" got renamed to "git-diff-files" while at it, since
that's what it really should be to match the other git-diff-xxx cases.

If you set SHA1_FILE_DIRECTORY to something else than .git/objects
git-pull-script will store the fetched files in a location the rest of
the tools does not expect.
git-prune-script also ignores this setting, but I think this is good,
because pruning a shared tree to fit a single project means throwing
away a lot of useful data. :-)

This patch replaces the usage of read_tree_with_tree_or_commit_sha1()

read_object_with_reference() and extends it to automatically
dereference not just "commit" objects but "tag" objects. With

ls-tree $tag
read-tree -m $(merge-base $tag $HEAD) $tag $HEAD
diff-cache $tag
diff-tree $tag $HEAD

This is an improved version of tar-tree, a streaming archive creator for
GIT. The major added feature is blocking; all write(2) calls now have a
size of 10240, just as GNU tar (and tape drives) likes them. The
buffering overhead does not seem to degrade performance because most
files in the repositories I tested this with are smaller than 10KB, so
we need fewer system calls.
File names are still restricted to 500 bytes and the archive format
currently only allows for files up to 8GB. Both restrictions can be
lifted if need be with more pax extended headers.
The archive format used is the pax interchange format, i.e. POSIX tar
format. It can be read by (and created with) GNU tar. If I read the
specs correctly tar-tree should now be standards compliant (modulo
bugs).
Because it streams the archive (think ls-tree merged with cat-file),
tar-tree doesn't need to create any temporary files. That makes it
quite fast.
It accepts tree IDs and commit IDs as first parameter. In the latter
case tar-tree tries to get the commit date out of the committer line.
Else all files in the archive are time-stamped with the current time.
An optional second parameter is used as a path prefix for all files in
the archive. Example:
$ tar-tree a2755a80f40e5794ddc20e00f781af9d6320fafb \

When diff-cache -p and friends are interrupted, they can leave
their temporary files behind. Also when the external diff
program is killed instead of exiting (this usually happens when
piping the output to a pager, which can cause SIGPIPE when the
user quits viewing the diff early), they incorrectly died
without cleaning their temporary file.
This fixes these problems.

This changes the way the default arguments to diff are built when
diff-cache and friends are invoked with -p and there is no
GIT_EXTERNAL_DIFF environment variable. It attempts to be more cg-patch
friendly by:
- Showing diffs against /dev/null to denote added or removed
files;
- Showing file modes for existing files as a comment after the
diff label.
Unfortunately with this change GIT_DIFF_CMD customization cannot
be supported easily anymore, so it has been dropped.
GIT_DIFF_OPTS customization to change diffs from unified to
context is still there, though.

With the recent "no-patch-by-default" change, the -s flag to the
show-diff command (and silent variable in the show-diff.c) became
meaningless. This deprecates it.
Cogito uses "show-diff -s" for the purpose of "I do not want the patch
text. I just want to know if something has potentially changed, in
which case I know you will have some output. I'll run update-cache
--refresh if you say something", so we cannot barf on seeing -s on our
command line yet.
