2012-06-15do not run pager with diff --no-index --quietLibravatar Jeff King1-3/+3
There is no point in running a pager when --quiet is given, since we are producing no output. The regular diff code path handles this already, because --quiet implies --exit-code, and we check for --exit-code when deciding not to run the pager. However, the "quiet implies exit-code" logic is done in diff_setup_done, and the no-index code path sets up its pager before running diff_setup_done, and misses this case. We can fix this by reordering our initialization. Currently we do: 1. read command line arguments into diff_options 2. Set pager if EXIT_CODE not requested 3. always set EXIT_CODE, since we are emulating traditional diff 4. call diff_setup_done We can fix the problem by moving pager initialization (step 2) after step 4. But step 3 must come after step 2 (since we want to know whether the _user_ requested --exit-code, not whether we turned it on unconditionally). So we must move both.

2012-06-15fix pager.diff with diff --no-indexLibravatar Jeff King1-6/+1
git-diff does not rely on the git wrapper to setup its pager; instead, it sets it up on its own after seeing whether --quiet or --exit-code has been specified. After diff_no_index was split off from cmd_diff, commit b3fde6c (git diff --no-index: default to page like other diff frontends, 2008-05-26) duplicated the one-liner from cmd_diff to turn on the pager. Later, commit 8f0359f (Allow pager of diff command be enabled/disabled, 2008-07-21) taught the the version in cmd_diff to respect the pager.diff config, but the version in diff_no_index was left behind. This meant that git -c pager.diff=0 diff a b would not use a pager, but git -c pager.diff=0 diff --no-index a b would. Let's fix it by factoring out a common function. While we're there, let's update the antiquated comment, which claims that the pager interferes with propagating the exit code; this has not been the case since ea27a18 (spawn pager via run_command interface, 2008-07-22).

2012-05-16diff --no-index: don't leak buffers in queue_diffLibravatar Bobby Powers1-2/+2
queue_diff uses two strbufs, and at the end of the function strbuf_reset was called. This only reset the length of the buffer - any allocated memory was leaked. Using strbuf_release fixes this.

2012-05-16diff --no-index: reset temporary buffer lengths on directory iterationLibravatar Bobby Powers1-0/+6
Commit 875b91b (diff --no-index: use strbuf for temporary pathnames, 2012-04-25) introduced a regression when using diff --no-index with directories. When iterating through a directory, the switch to strbuf from heap-allocated char arrays caused paths to form like 'dir/file1', 'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected. Avoid this by resetting the paths variables to their original length before each iteration.

2012-04-16diff: avoid stack-buffer-read-overrun for very long nameLibravatar Jim Meyering1-0/+2

2009-02-18Skip timestamp differences for diff --no-indexLibravatar Michael Spang1-0/+1
We display empty diffs for files whose timestamps have changed. Usually, refreshing the index makes those empty diffs go away. However, when not using the index they are not very useful and there is no option to suppress them. This forces on the skip_stat_unmatch option for diff --no-index, suppressing any empty diffs. This option is also used for diffs against the index when "diff.autorefreshindex" is set, but that option does not apply to diff --no-index.

2008-08-30diff: vary default prefix depending on what are comparedLibravatar Junio C Hamano1-0/+1
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>

2008-05-24"git diff": do not ignore index without --no-indexLibravatar Junio C Hamano1-0/+231
Even if "foo" and/or "bar" does not exist in index, "git diff foo bar" should not change behaviour drastically from "git diff foo bar baz" or "git diff foo". A feature that "sometimes works and is handy" is an unreliable cute hack. "git diff foo bar" outside a git repository continues to work as a more colourful alternative to "diff -u" as before.
