git/diff.c, branch v1.2.2

find_unique_abbrev() simplification.

2006-02-10T09:51:12Z

Earlier it did not grok the 0{40} SHA1 very well, but what it needed to do was to find the shortest 0{N} that is not used as a valid object name to be consistent with the way names of valid objects are abbreviated. This makes some users simpler. Signed-off-by: Junio C Hamano

Allow diff and index commands to be interrupted

2006-02-02T03:47:52Z

So far, e.g. git-update-index --refresh was basically uninterruptable by ctrl-c, since it hooked the SIGINT handler, but that handler would only unlink the lockfile but not actually quit. This makes it propagate the signal to the default handler. Note that I expected it to work without resetting the signal handler to SIG_DFL, but without that it ended in an infinite loop of tgkill()s - is my glibc violating SUS or what?

diff --abbrev= option fix.

2006-01-28T08:09:39Z

Earier specifying an abbreviation shorter than minimum fell back to full 40 letters, which was nonsense. Make it to fall back to the minimum number (currently 4). Signed-off-by: Junio C Hamano

abbrev cleanup: use symbolic constants

2006-01-28T08:09:38Z

The minimum length of abbreviated object name was hardcoded in different places to be 4, risking inconsistencies in the future. Also there were three different "default abbreviation precision". Use two C preprocessor symbols to clean up this mess. Signed-off-by: Junio C Hamano

Handle symlinks graciously

2005-12-27T02:33:27Z

This patch converts a stat() to an lstat() call, thereby fixing the case when the date of a symlink was not the same as the one recorded in the index. The included test case demonstrates this. This is for the case that the symlink points to a non-existing file. If the file exists, worse things than just an error message happen.

avoid asking ?alloc() for zero bytes.

2005-12-27T01:23:59Z

Avoid asking for zero bytes when that change simplifies overall logic. Later we would change the wrapper to ask for 1 byte on platforms that return NULL for zero byte request. Signed-off-by: Junio C Hamano

diff: --abbrev option

2005-12-20T02:32:44Z

When I show transcripts to explain how something works, I often find myself hand-editing the diff-raw output to shorten various object names in the output. This adds --abbrev option to the diff family, which shortens diff-raw output and diff-tree commit id headers. Signed-off-by: Junio C Hamano

Move diff.renamelimit out of default configuration.

2005-11-22T07:00:50Z

Otherwise we would end up linking all the unneeded stuff into git-daemon only to link with git_default_config. Signed-off-by: Junio C Hamano

rename/copy score parsing updates.

2005-11-21T22:54:33Z

Better variant, which handles stuff like "4.5%" and rejects "192.168.0.1". Additionally, make sure numbers are unsigned (I'm making them unsigned long just for the hell of it), to make sure that artificial wraparound scenarios don't cause harm. -hpa [jc: with this, -M100 changes its meaning back to 10%. People wanting to say "pure renames only" should now say -M100% or -M1.0; sounds a bit like an earthquake, but arguably things are more consistent this way ;-)] Signed-off-by: Junio C Hamano
