2006-09-02Replace uses of strdup with xstrdup.Libravatar Shawn Pearce1-2/+2
Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.

2006-08-23Convert memcpy(a,b,20) to hashcpy(a,b).Libravatar Shawn Pearce1-3/+3
This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet. Fixed the cast in the latter hunk to combine-diff.c which was wrong in the original. Also converted ones left-over in combine-diff.c, diff-lib.c and upload-pack.c ] Signed-off-by: Shawn O.

2006-08-03diff.c: do not use pathname comparison to tell renamesLibravatar Junio C Hamano1-5/+1
The final output from diff used to compare pathnames between preimage and postimage to tell if the filepair is a rename/copy. By explicitly marking the filepair created by diffcore_rename(), the output routine, resolve_rename_copy(), does not have to do so anymore. This helps feeding a filepair that has different pathnames in one and two elements to the diff machinery (most notably, comparing two blobs). Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-24Colorize 'commit' lines in log uiLibravatar Jeff King1-17/+11
When paging through the output of git-whatchanged, the color cues help to visually navigate within a diff. However, it is difficult to notice when a new commit starts, because the commit and log are shown in the "normal" color. This patch colorizes the 'commit' line, customizable through diff.colors.commit and defaulting to yellow. As a side effect, some of the diff color engine (slot enum, get_color) has become accessible outside of diff.c. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-08diff: do not use configuration magic at the core-levelLibravatar Junio C Hamano1-1/+7
The Porcelainish has become so much usable as the UI that there is not much reason people should be using the core programs by hand anymore. At this point we are better off making the behaviour of the core programs predictable by keeping them unaffected by the configuration variables. Otherwise they will become very hard to use as reliable building blocks. For example, "git-commit -a" internally uses git-diff-files to figure out the set of paths that need to be updated in the index, and we should never allow diff.renames that happens to be in the configuration to interfere (or slow down the process). The UI level configuration such as showing renamed diff and coloring are still honored by the Porcelainish ("git log" family and "git diff"), but not by the core anymore.

2006-07-03Make zlib compression level configurable, and change default.Libravatar Joachim B Haga1-1/+1
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.

This fixes various problems in the new diff options code. - Fix --cc/-c --patch; it showed two-tree diff used internally. - Use "---\n" only where it matters -- that is, use it immediately after the commit log text when we show a commit log and something else before the patch text. - Do not output spurious extra "\n"; have an extra newline after the commit log text always when we have diff output and we are not doing oneline. - When running a pickaxe you need to go recursive.

setup_revisions() calls diff_setup_done() before we can set default value for output_format.

2006-06-22Tweak diff colorsLibravatar Linus Torvalds1-41/+58
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..
