| * diff: refactor COLOR_DIFF from a flag into an intJeff King2011-08-181-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

So far, format callback functions are not used for anything but 2-way diffs. A callback is given a diff_queue_struct, which is an array of diff_filepair. As its name suggests, a diff_filepair is a _pair_ of diff_filespec that represents a single preimage and a single postimage. Since "diff -c" is to compare N parents with a single merge result and filter out any paths whose result match one (or more) of the parent(s), its output has to be able to represent N preimages and 1 postimage. For this reason, a callback function that inspects a diff_filepair that results from this new infrastructure can and is expected to view the preimage side (i.e. pair->one) as an array of diff_filespec. Each element in the array, except for the last one, is marked with "has_more_entries" bit, so that the same callback function can be used for 2-way diffs and combined diffs.

This generally lead to us printing "Binary files differ" when we could show a combined diff of the converted text. This patch converts file contents according to textconv attributes. The implementation is slightly ugly; because the textconv code is tightly linked with the diff_filespec code, we temporarily create a diff_filespec during conversion. In practice, though, this should not create a performance problem. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Instead, we consider a combined diff to be binary if any of the input blobs is binary. To show a binary combined diff, we indicate "Binary blobs differ"; the "index" meta line will show which parents had which blob.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ever since the xdiff library had been introduced to git, all its callers have used the flag XDF_NEED_MINIMAL. It makes sure that the smallest possible diff is produced, but that takes quite some time if there are lots of differences that can be expressed in multiple ways. This flag makes a difference for only 0.1% of the non-merge commits in the git repo of Linux, both in terms of diff size and execution time. The patches there are mostly nice and small. SungHyun Nam however reported a case in a different repo where a diff took more than 20 times longer to generate with XDF_NEED_MINIMAL than without. Rebasing became really slow. This patch removes this flag from all callers. The default of xdiff is saner because it has minimal to no impact in the normal case of small diffs and doesn't incur that much of a speed penalty for large ones. A follow-up patch may introduce a command line option to set the flag if the user needs it, similar to GNU diff's -d/--minimal.

* combined diff: correctly handle truncated fileThomas Rast2010-04-171-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | Consider an evil merge of two commits A and B, both of which have a file 'foo', but the merge result does not have that file. The combined-diff code learned in 4462731 (combine-diff: do not punt on removed or added files., 2006-02-06) to concisely show only the removal, since that is the evil part and the previous contents are presumably uninteresting. However, to diagnose an empty merge result, it overloaded the variable that holds the file's length. This means that the check also triggers for truncated files. Consequently, such files were not shown in the diff at all despite the merge being clearly evil. Fix this by adding a new variable that distinguishes whether the file was deleted (which is the case 4462731 handled) or truncated. In the truncated case, we show the full combined diff again, which is rather spammy but at least does not hide the evilness.

The problem is that "less" hides a carriage-return only at the end of the line, immediately before a line feed. The colored diff output does not take this into account, and emits four element sequence for each line: - force this color; - the line up to but not including the terminating line feed; - reset color - line feed. By including the carriage return at the end of the line in the second item, we are breaking the smart our pager has in order not to show "^M". This can be fixed by changing the sequence to: - force this color; - the line up to but not including the terminating end-of-line; - reset color - end-of-line. where end-of-line is either a single linefeed or a CRLF pair. When the output is not colored, "force this color" and "reset color" sequences are both empty, so we won't have this problem with or without this patch.

* combine-diff: Fix path quotingJunio C Hamano2007-12-261-10/+31
| | | | | | | | | | | | Earlier when showing combined diff, the filenames on the ---/+++ header lines were quoted incorrectly. a/ (or b/) prefix was output literally and then the path was output, with c-quoting. This fixes the quoting logic, and while at it, adjusts the code to use the customizable prefix (a_prefix and b_prefix) introduced recently. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* xdl_diff: identify call sites.Junio C Hamano2007-12-131-1/+1
| | | | | | | | This inserts a new function xdi_diff() that currently does not do anything other than calling the underlying xdl_diff() to the callchain of current callers of xdl_diff() function. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Make the diff_options bitfields be an unsigned with explicit masks.Pierre Habouzit2007-11-111-5/+5
| | | | | | | reverse_diff was a bit-value in disguise, it's merged in the flags now. Signed-off-by: Pierre Habouzit <madcoder@debian.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Full rework of quote_c_style and write_name_quoted.Pierre Habouzit2007-09-201-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | * quote_c_style works on a strbuf instead of a wild buffer. * quote_c_style is now clever enough to not add double quotes if not needed. * write_name_quoted inherits those advantages, but also take a different set of arguments. Now instead of asking for quotes or not, you pass a "terminator". If it's \0 then we assume you don't want to escape, else C escaping is performed. In any case, the terminator is also appended to the stream. It also no longer takes the prefix/prefix_len arguments, as it's seldomly used, and makes some optimizations harder. * write_name_quotedpfx is created to work like write_name_quoted and take the prefix/prefix_len arguments. Thanks to those API changes, diff.c has somehow lost weight, thanks to the removal of functions that were wrappers around the old write_name_quoted trying to give it a semantics like the new one, but performing a lot of allocations for this goal. Now we always write directly to the stream, no intermediate allocation is performed. As a side effect of the refactor in builtin-apply.c, the length of the bar graphs in diffstats are not affected anymore by the fact that the path was clipped.
