2008-09-06diff --quiet: make it synonym to --exit-code >/dev/nullJunio C Hamano
The point of --quiet was to return the status as early as possible without doing any extra processing. Well behaved scripts, when they expect to run many diff operations inside, are supposed to run "update-index --refresh" upfront; we do not want them to pay the price of iterating over the index and comparing the contents to fix the stat dirtiness, and we avoided most of the processing in diffcore_std() when --quiet is in effect. But scripts that adhere to the good practice won't have to pay any more price than the necessary lstat(2) that will report stat cleanliness, as long as only -q is given without any fancier diff options. More importantly, users who do ask for "--quiet -M --filter=D" (in order to notice only the deletion, not paths that disappeared only because they have been renamed away) deserve to get the result they asked for, even it means they have to pay the extra price; the alternative is to get a cheap early return that gives a result they did not ask for, which is much worse.

2008-09-06diff Porcelain: do not disable auto index refreshing on -C -CJunio C Hamano
When we enabled the automatic refreshing of the index to "diff" Porcelain, we disabled it when --find-copies-harder was asked, but there is no good reason to do so. In the following command sequence, the first "diff" shows an "empty" diff exposing stat dirtyness, while the second one does not. $ >foo $ git add foo $ touch foo $ git diff -C -C $ git diff -C This fixes the inconsistency.

2008-08-30diff: vary default prefix depending on what are comparedJunio C Hamano
With a new configuration "diff.mnemonicprefix", "git diff" shows the differences between various combinations of preimage and postimage trees with prefixes different from the standard "a/" and "b/". Hopefully this will make the distinction stand out for some people. "git diff" compares the (i)ndex and the (w)ork tree; "git diff HEAD" compares a (c)ommit and the (w)ork tree; "git diff --cached" compares a (c)ommit and the (i)ndex; "git-diff HEAD:file1 file2" compares an (o)bject and a (w)ork tree entity; "git diff --no-index a b" compares two non-git things (1) and (2). Because these mnemonics now have meanings, they are swapped when reverse diff is in effect and this feature is enabled. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-08-30diff: Help "less" hide ^M from the outputJunio C Hamano
When the tracked contents have CRLF line endings, colored diff output shows "^M" at the end of output lines, which is distracting, even though the pager we use by default ("less") knows to hide them. 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.

Fix '--dirstat' with cross-directory renaming for-each-ref: Allow a trailing slash in the patterns
2008-08-29Fix '--dirstat' with cross-directory renamingLinus Torvalds
The dirstat code depends on the fact that we always generate diffs with the names sorted, since it then just does a single-pass walk-over of the sorted list of names and how many changes there were. The sorting means that all files are nicely grouped by directory. That all works fine. Except when we have rename detection, and suddenly the nicely sorted list of pathnames isn't all that sorted at all. And now the single-pass dirstat walk gets all confused, and you can get results like this: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 3.0% arch/powerpc/configs/ 6.8% arch/arm/configs/ 2.7% arch/powerpc/configs/ 4.2% arch/arm/configs/ 5.6% arch/powerpc/configs/ 8.4% arch/arm/configs/ 5.5% arch/powerpc/configs/ 23.3% arch/arm/configs/ 8.6% arch/powerpc/configs/ 4.0% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ The trivial fix is to add a sorting pass, fixing it to: [torvalds@nehalem linux]$ git diff --dirstat=2 -M v2.6.27-rc4..v2.6.27-rc5 43.0% arch/arm/configs/ 25.5% arch/powerpc/configs/ 5.3% arch/ 4.4% drivers/usb/musb/ 4.0% drivers/watchdog/ 7.6% drivers/ 3.5% fs/ Spot the difference. In case anybody wonders: it's because of a ton of renames from {include/asm-blackfin => arch/blackfin/include/asm} that just totally messed up the file ordering in between arch/arm and arch/powerpc.

2008-08-20diff --check: do not get confused by new blank lines in the middleJunio C Hamano
The code remembered that the last diff output it saw was an empty line, and tried to reset that state whenever it sees a context line, a non-blank new line, or a new hunk. However, this codepath asks the underlying diff engine to feed diff without any context, and the "just saw an empty line" state was not reset if you added a new blank line in the last hunk of your patch, even if it is not the last line of the file.

2008-08-14xdiff-interface: hide the whole "xdiff_emit_state" business from the callerJunio C Hamano
This further enhances xdi_diff_outf() interface so that it takes two common parameters: the callback function that processes one line at a time, and a pointer to its application specific callback data structure. xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes these two away inside it, which is used by the lowest level output function in the xdiff_outf() callchain, consume_one(), to call back to the application layer. With this restructuring, we lift the requirement that the caller supplied callback data structure embeds xdiff_emit_state structure as its first member.

2008-08-05diff.renamelimit is a basic diff configurationLinus Torvalds
The configuration was added as a core option in 3299c6f (diff: make default rename detection limit configurable., 2005-11-15), but 9ce392f (Move diff.renamelimit out of default configuration., 2005-11-21) separated diff-related stuff out of the core. Up to that point it was Ok. When we separated the Porcelain options out of the git_diff_config in 83ad63c (diff: do not use configuration magic at the core-level, 2006-07-08), we should have been more careful. This mistake made diff-tree plumbing and git-show Porcelain to notice different set of renames when the user explicitly asked for rename detection. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-07-29format-patch: Produce better output with --inline or --attachKevin Ballard
This patch makes two small changes to improve the output of --inline and --attach. The first is to write a newline preceding the boundary. This is needed because MIME defines the encapsulation boundary as including the preceding CRLF (or in this case, just LF), so we should be writing one. Without this, the last newline in the pre-diff content is consumed instead. The second change is to always write the line termination character (default: newline) even when using --inline or --attach. This is simply to improve the aesthetics of the resulting message. When using --inline an email client should render the resulting message identically to the non-inline version. And when using --attach this adds a blank line preceding the attachment in the email, which is visually attractive.

* maint: diff: reset color before printing newline
2008-06-16diff: reset color before printing newlineSZEDER Gábor
It worked that way since commit 50f575fc (Tweak diff colors, 2006-06-22), but commit c1795bb0 (Unify whitespace checking, 2007-12-13) changed it. This patch restores the old behaviour. Besides Linus' arguments in the log message of 50f575fc, resetting color before printing newline is also important to keep 'git add --patch' happy. If the last line(s) of a file are removed, then that hunk will end with a colored line. However, if the newline comes before the color reset, then the diff output will have an additional line at the end containing only the reset sequence. This causes trouble in git-add--interactive.perl's parse_diff function, because @colored will have one more element than @diff, and that last element will contain the color reset. The elements of these arrays will then be copied to @hunk, but only as many as the number of elements in @diff. As a result the last color reset is lost and all subsequent terminal output will be printed in color. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-06-14avoid trailing whitespace in zero-change diffstat linesJeff King
In some cases, we produce a diffstat line even though no lines have changed (e.g., because of an exact rename). In this case, there is no +/- "graph" after the number of changed lines. However, we output the space separator unconditionally, meaning that these lines contained a trailing space character. This isn't a huge problem, but in cleaning up the output we are able to eliminate some trailing whitespace from a test vector.
