Merge branch 'jk/add-i-use-pathspecs'

2017-03-17T20:50:26Z

"git add -p " unnecessarily expanded the pathspec to a list of individual files that matches the pathspec by running "git ls-files ", before feeding it to "git diff-index" to see which paths have changes, because historically the pathspec language supported by "diff-index" was weaker. These days they are equivalent and there is no reason to internally expand it. This helps both performance and avoids command line argument limit on some platforms. * jk/add-i-use-pathspecs: add--interactive: do not expand pathspecs with ls-files

add--interactive: do not expand pathspecs with ls-files

2017-03-14T20:27:23Z

When we want to get the list of modified files, we first expand any user-provided pathspecs with "ls-files", and then feed the resulting list of paths as arguments to "diff-index" and "diff-files". If your pathspec expands into a large number of paths, you may run into one of two problems: 1. The OS may complain about the size of the argument list, and refuse to run. For example: $ (ulimit -s 128 && git add -p drivers) Can't exec "git": Argument list too long at .../git-add--interactive line 177. Died at .../git-add--interactive line 177. That's on the linux.git repository, which has about 20K files in the "drivers" directory (none of them modified in this case). The "ulimit -s" trick is necessary to show the problem on Linux even for such a gigantic set of paths. Other operating systems have much smaller limits (e.g., a real-world case was seen with only 5K files on OS X). 2. Even when it does work, it's really slow. The pathspec code is not optimized for huge numbers of paths. Here's the same case without the ulimit: $ time git add -p drivers No changes. real 0m16.559s user 0m53.140s sys 0m0.220s We can improve this by skipping "ls-files" completely, and just feeding the original pathspecs to the diff commands. This solution was discussed in 2010: http://public-inbox.org/git/20100105041438.GB12574@coredump.intra.peff.net/ but at the time the diff code's pathspecs were more primitive than those used by ls-files (e.g., they did not support globs). Making the change would have caused a user-visible regression, so we didn't. Since then, the pathspec code has been unified, and the diff commands natively understand pathspecs like '*.c'. This patch implements that solution. That skips the argument-list limits, and the result runs much faster: $ time git add -p drivers No changes. real 0m0.149s user 0m0.116s sys 0m0.080s There are two new tests. The first just exercises the globbing behavior to confirm that we are not causing a regression there. The second checks the actual argument behavior using GIT_TRACE. We _could_ do it with the "ulimit -s" trick, as above. But that would mean the test could only run where "ulimit -s" works. And tests of that sort are expensive, because we have to come up with enough files to actually bust the limit (we can't just shrink the "128" down infinitely, since it is also the in-program stack size). Finally, two caveats and possibilities for future work: a. This fixes one argument-list expansion, but there may be others. In fact, it's very likely that if you run "git add -i" and select a large number of modified files that the script would try to feed them all to a single git command. In practice this is probably fine. The real issue here is that the argument list was growing with the _total_ number of files, not the number of modified or selected files. b. If the repository contains filenames with literal wildcard characters (e.g., "foo*"), the original code expanded them via "ls-files" and then fed those wildcard names to "diff-index", which would have treated them as wildcards. This was a bug, which is now fixed (though unless you really go through some contortions with ":(literal)", it's likely that your original pathspec would match whatever the accidentally-expanded wildcard would anyway). So this takes us one step closer to working correctly with files whose names contain wildcard characters, but it's likely that others remain (e.g., if "git add -i" feeds the selected paths to "git add").

add--interactive: fix missing file prompt for patch mode with "-i"

2017-03-02T18:10:38Z

When invoked as "git add -i", each menu interactive menu option prompts the user to select a list of files. This includes the "patch" option, which gets the list before starting the hunk-selection loop. As "git add -p", it behaves differently, and jumps straight to the hunk selection loop. Since 0539d5e6d (i18n: add--interactive: mark patch prompt for translation, 2016-12-14), the "add -i" case mistakenly jumps to straight to the hunk-selection loop. Prior to that commit the distinction between the two cases was managed by the $patch_mode variable. That commit used $patch_mode for something else, and moved the old meaning to the "$cmd" variable. But it forgot to update the $patch_mode check inside patch_update_cmd() which controls the file-list behavior. The simplest fix would be to change that line to check $cmd. But while we're here, let's use a less obscure name for this flag: $patch_mode_only, a boolean which tells whether we are in full-interactive mode or only in patch-mode.

git add -i: replace \t with blanks in the help message

2017-02-22T20:51:00Z

Within the help message of 'git add -i', the 'diff' command uses one tab character and blanks to create the space between the name and the description while the others use blanks only. So if the tab size is not at 4 characters, this description will not be in range. Replace the tab character with blanks. Signed-off-by: Ralf Thielow Signed-off-by: Junio C Hamano

Merge branch 'jc/retire-compaction-heuristics'

2017-01-10T23:24:27Z

"git diff" and its family had two experimental heuristics to shift the contents of a hunk to make the patch easier to read. One of them turns out to be better than the other, so leave only the "--indent-heuristic" option and remove the other one. * jc/retire-compaction-heuristics: diff: retire "compaction" heuristics

diff: retire "compaction" heuristics

2016-12-23T20:32:22Z

When a patch inserts a block of lines, whose last lines are the same as the existing lines that appear before the inserted block, "git diff" can choose any place between these existing lines as the boundary between the pre-context and the added lines (adjusting the end of the inserted block as appropriate) to come up with variants of the same patch, and some variants are easier to read than others. We have been trying to improve the choice of this boundary, and Git 2.11 shipped with an experimental "compaction-heuristic". Since then another attempt to improve the logic further resulted in a new "indent-heuristic" logic. It is agreed that the latter gives better result overall, and the former outlived its usefulness. Retire "compaction", and keep "indent" as an experimental feature. The latter hopefully will be turned on by default in a future release, but that should be done as a separate step.
