* Make zlib compression level configurable, and change default.Joachim B Haga2006-07-03
| | | | | | | | | | | | | | | | With the change in default, "git add ." on kernel dir is about twice as fast as before, with only minimal (0.5%) change in object size. The speed difference is even more noticeable when committing large files, which is now up to 8 times faster. The configurability is through setting core.compression = [-1..9] which maps to the zlib constants; -1 is the default, 0 is no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest.

* Tweak diff colorsLinus Torvalds2006-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch does: - always reset the color _before_ printing out the newline. This is actually important. You (and Johannes) didn't see it, because it only matters if you set the background, but if you don't do this, you get some random and funky behaviour if you pick a color with a non-default background (which still potentially has problems with tabs etc, but less so). - allow people to have a different color for the "file headers" (DIFF_METAINFO) and for the "fragment header" (DIFF_FRAGINFO). Also, make a difference between "normal color" and "reset colors" - default to red/green for old/new lines. That's the norm, I'd think. - instead of that eye-popping (and eye-ball-with-a-fondue-fork-popping) purple color for metadata, use bold-face for file headers, and cyan for the frag headers. I actually prefer the "gray background" for that, but it only works well in xterms, so COLOR_CYAN it is..

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS environment variable, but strangely enough we would _not_ parse them as part of the normal diff command line (where we only accepted "-u"). This adds parsing of -U and --unified, both with an optional numeric argument. So now you can just say git diff --unified=5 to get a unified diff with a five-line context, instead of having to do something silly like GIT_DIFF_OPTS="--unified=5" git diff -u (that silly format does continue to still work, of course).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the user interface and generated diff data format. * "diff --binary" is used to signal that we want an e-mailable binary patch. It implies --full-index and -p. * "apply --allow-binary-replacement" acquired a short synonym "apply --binary". * After the "GIT binary patch\n" header line there is a token to record which binary patch mechanism was used, so that we can extend it later. Currently there are two mechanisms defined: "literal" and "delta". The former records the deflated postimage and the latter records the deflated delta from the preimage to postimage. For purely implementation convenience, I added the deflated length after these "literal/delta" tokens (otherwise the decoding side needs to guess and reallocate the buffer while inflating). Improvement patches are very welcomed. Signed-off-by: Junio C Hamano <junkio@cox.net>
| * binary patch.Junio C Hamano2006-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds "binary patch" to the diff output and teaches apply what to do with them. On the diff generation side, traditionally, we said "Binary files differ\n" without giving anything other than the preimage and postimage object name on the index line. This was good enough for applying a patch generated from your own repository (very useful while rebasing), because the postimage would be available in such a case. However, this was not useful when the recipient of such a patch via e-mail were to apply it, even if the preimage was available. This patch allows the diff to generate "binary" patch when operating under --full-index option. The binary patch follows the usual extended git diff headers, and looks like this: "GIT binary patch\n" <length byte><data>"\n" ... "\n" Each line is prefixed with a "length-byte", whose value is upper or lowercase alphabet that encodes number of bytes that the data on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ..., 'Z' means 26, 'a' means 27, ...). <data> is 1 or more groups of 5-byte sequence, each of which encodes up to 4 bytes in base85 encoding. Because 52 / 4 * 5 = 65 and we have the length byte, an output line is capped to 66 characters. The payload is the same diff-delta as we use in the packfiles. On the consumption side, git-apply now can decode and apply the binary patch when --allow-binary-replacement is given, the diff was generated with --full-index, and the receiving repository has the preimage blob, which is the same condition as it always required when accepting an "Binary files differ\n" patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we cut off the front of a filename to make it fit on the line, we add a "..." in front. However, the way the "git diff" code was written, we will never reset the prefix back to the empty string, so every single filename afterwards will have the "..." prefix, whether appropriate or not. You can see this with "git diff v2.6.16.." on the current kernel tree, since there are filenames with long names that changed there: [ snip snip ] Documentation/filesystems/vfs.txt | 229 .../firmware_class/firmware_sample_driver.c | 3 .../firmware_sample_firmware_class.c | 1 ...Documentation/fujitsu/frv/kernel-ABI.txt | 192 ...Documentation/hwmon/w83627hf | 4 [ snip snip ] notice how the two Documentation/firmware** filenames caused the "..." to be added, but then the later filenames don't want it, and it also screws up the alignment of the line numbering afterwards. Trivially fixed by moving the declaration (and initial setting) of the "prefix" variable into the for-loop where it is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | Somebody on the #git channel complained that the sha1_to_hex() thing uses a static buffer which caused an error message to show the same hex output twice instead of showing two different ones. That's pretty easily rectified by making it uses a simple LRU of a few buffers, which also allows some other users (that were aware of the buffer re-use) to be written in a more straightforward manner.

The updated diff-files uses revision.c::setup_revisions() infrastructure to parse its command line arguments, which means the pathname arguments are checked more strictly than before. The tests are adjusted to separate possibly missing paths from the rest of arguments with double-dashes, to show the kosher way. As Linus pointed out, renaming diff.c to diff-lib.c was simply stupid, so I am renaming it back. The new diff-lib.c is to contain pieces extracted from diff brothers.
