2020-02-07t4013: make test hash independentbrian m. carlson
This test produces a large number of diff formats and compares the output with test files that have content specific to SHA-1. Since we are more interested in the format of the diffs, and not their specific values, which are tested elsewhere, add a function which uses sed to transform these specific object IDs into generic ones of the right size, which we can then compare.

2019-05-29diff-parseopt: restore -U (no argument) behaviorNguyễn Thái Ngọc Duy
Before d473e2e0e8 (diff.c: convert -U|--unified, 2019-01-27), -U and --unified are implemented with a custom parser opt_arg() in diff.c. I didn't check this code carefully and not realize that it's the equivalent of PARSE_OPT_NONEG | PARSE_OPT_OPTARG. In other words, if -U is specified without any argument, the option should be accepted, and the default value should be used. Without PARSE_OPT_OPTARG, parse_options() will reject this case and cause a regression.

2019-01-24combine-diff: treat --dirstat like --statJeff King
Currently "--cc --dirstat" will show nothing for a merge. Like --shortstat and --summary in the previous two patches, it probably makes sense to treat it like we do --stat, and show a stat against the first-parent. This case is less obviously correct than for --shortstat and --summary, as those are basically variants of --stat themselves. It's possible we could develop a multi-parent combined dirstat format, in which case we might regret defining this first-parent behavior. But the same could be said for --stat, and in the 12+ years of it showing first-parent stats, nobody has complained. So showing the first-parent dirstat is at least _useful_, and if we later develop a clever multi-parent stat format, we'd probably have to deal with --stat anyway.

2019-01-24combine-diff: treat --summary like --statJeff King
Currently "--cc --summary" on a merge shows nothing. Since we show "--cc --stat" as a stat against the first parent, and because --summary is typically used in combination with --stat, it makes sense to treat them both the same way. Note that we have to tweak t4013's setup a bit to test this case, as the existing merges do not have any --summary results against their first parent. But since the merge at the tip of 'master' does add and remove files with respect to the second parent, we can just make a reversed doppelganger merge where the parents are swapped.

2019-01-24combine-diff: treat --shortstat like --statJeff King
The --stat of a combined diff is defined as the first-parent stat, going all the way back to 965f803c32 (combine-diff: show diffstat with the first parent., 2006-04-17). Naturally, we gave --numstat the same treatment in 74e2abe5b7 (diff --numstat, 2006-10-12). But --shortstat, which is really just the final line of --stat, does nothing, which produces confusing results: $ git show --oneline --stat eab7584e37 eab7584e37 Merge branch 'en/show-ref-doc-fix' Documentation/git-show-ref.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) $ git show --oneline --shortstat eab7584e37 eab7584e37 Merge branch 'en/show-ref-doc-fix' [nothing! We'd expect to see the "1 file changed..." line] This patch teaches combine-diff to treats the two formats identically.

2018-11-20tests: send "bug in the test script" errors to the script's stderrSZEDER Gábor
Some of the functions in our test library check that they were invoked properly with conditions like this: test "$#" = 2 || error "bug in the test script: not 2 parameters to test-expect-success" If this particular condition is triggered, then 'error' will abort the whole test script with a bold red error message [1] right away. However, under certain circumstances the test script will be aborted completely silently, namely if: - a similar condition in a test helper function like 'test_line_count' is triggered, - which is invoked from the test script's "main" shell [2], - and the test script is run manually (i.e. './t1234-foo.sh' as opposed to 'make t1234-foo.sh' or 'make test') [3] - and without the '--verbose' option, because the error message is printed from within 'test_eval_', where standard output is redirected either to /dev/null or to a log file. The only indication that something is wrong is that not all tests in the script are executed and at the end of the test script's output there is no "# passed all N tests" message, which are subtle and can easily go unnoticed, as I had to experience myself. Send these "bug in the test script" error messages directly to the test scripts standard error and thus to the terminal, so those bugs will be much harder to overlook. Instead of updating all ~20 such 'error' calls with a redirection, let's add a BUG() function to 'test-lib.sh', wrapping an 'error' call with the proper redirection and also including the common prefix of those error messages, and convert all those call sites [4] to use this new BUG() function instead. [1] That particular error message from 'test_expect_success' is printed in color only when running with or without '--verbose'; with '--tee' or '--verbose-log' the error is printed without color, but it is printed to the terminal nonetheless. [2] If such a condition is triggered in a subshell of a test, then 'error' won't be able to abort the whole test script, but only the subshell, which in turn causes the test to fail in the usual way, indicating loudly and clearly that something is wrong. [3] Well, 'error' aborts the test script the same way when run manually or by 'make' or 'prove', but both 'make' and 'prove' pay attention to the test script's exit status, and even a silently aborted test script would then trigger those tools' usual noticable error messages. [4] Strictly speaking, not all those 'error' calls need that redirection to send their output to the terminal, see e.g. 'test_expect_success' in the opening example, but I think it's better to be consistent.

2018-02-27diff: add --compact-summaryNguyễn Thái Ngọc Duy
Certain information is currently shown with --summary, but when used in combination with --stat it's a bit hard to read since info of the same file is in two places (--stat and --summary). On top of that, commits that add or remove files double the number of display lines, which could be a lot if you add or remove a lot of files. --compact-summary embeds most of --summary back in --stat in the little space between the file name part and the graph line, e.g. with commit 0433d533f1: Documentation/merge-config.txt | 4 + builtin/merge.c | 2 + ...-pull-verify-signatures.sh (new +x) | 81 ++++++++++++++ t/t7612-merge-verify-signatures.sh | 45 ++++++++ 4 files changed, 132 insertions(+) It helps both condensing information and saving some text space. What's new in diffstat is: - A new 0644 file is shown as (new) - A new 0755 file is shown as (new +x) - A new symlink is shown as (new +l) - A deleted file is shown as (gone) - A mode change adding executable bit is shown as (mode +x) - A mode change removing it is shown as (mode -x) Note that --compact-summary does not contain all the information --summary provides.

2017-12-06t4013: prepare for upcoming "diff --raw --abbrev" output format changeAnn T Ropea
Most of the t4013 tests go through a list of sample command lines, and each of them is executed and its output compared with an expected one stored in t4013/ directory. Allow these lines to begin with a colon followed by magic word(s) so that test conditions can easily be tweaked. The expected use that will happen in later steps of this is to run tests expecting the traditional output and run the same test without the GIT_PRINT_SHA1_ELLIPSIS=yes environment exported for (perhaps some of) them, which will have to expect different output. Since all of the existing tests are meant to run with the environment, use the magic word "noellipses" to cause the variable not to be set and exported. As this step does not add any new test with the magic word, all tests still run with the environment variable, expecting the traditional output, but it will change soon.

2016-12-08diff: handle --no-abbrev in no-index caseJack Bates
There are two different places where the --no-abbrev option is parsed, and two different places where SHA-1s are abbreviated. We normally parse --no-abbrev with setup_revisions(), but in the no-index case, "git diff" calls diff_opt_parse() directly, and diff_opt_parse() didn't handle --no-abbrev until now. (It did handle --abbrev, however.) We normally abbreviate SHA-1s with find_unique_abbrev(), but commit 4f03666 ("diff: handle sha1 abbreviations outside of repository, 2016-10-20) recently introduced a special case when you run "git diff" outside of a repository. setup_revisions() does also call diff_opt_parse(), but not for --abbrev or --no-abbrev, which it handles itself. setup_revisions() sets rev_info->abbrev, and later copies that to diff_options->abbrev. It handles --no-abbrev by setting abbrev to zero. (This change doesn't touch that.) Setting abbrev to zero was broken in the outside-of-a-repository special case, which until now resulted in a truly zero-length SHA-1, rather than taking zero to mean do not abbreviate. The only way to trigger this bug, however, was by running "git diff --raw" without either the --abbrev or --no-abbrev options, because 1) without --raw it doesn't respect abbrev (which is bizarre, but has been that way forever), 2) we silently clamp --abbrev=0 to MINIMUM_ABBREV, and 3) --no-abbrev wasn't handled until now. The outside-of-a-repository case is one of three no-index cases. The other two are when one of the files you're comparing is outside of the repository you're in, and the --no-index option.

2016-09-01graph: add support for --line-prefix on all graph-aware outputJacob Keller
Add an extension to git-diff and git-log (and any other graph-aware displayable output) such that "--line-prefix=<string>" will print the additional line-prefix on every line of output. To make this work, we have to fix a few bugs in the graph API that force graph_show_commit_msg to be used only when you have a valid graph. Additionally, we extend the default_diff_output_prefix handler to work even when no graph is enabled. This is somewhat of a hack on top of the graph API, but I think it should be acceptable here. This will be used by a future extension of submodule display which displays the submodule diff as the actual diff between the pre and post commit in the submodule project.

2016-02-25diff: activate diff.renames by defaultMatthieu Moy
Rename detection is a very convenient feature, and new users shouldn't have to dig in the documentation to benefit from it. Potential objections to activating rename detection are that it sometimes fail, and it is sometimes slow. But rename detection is already activated by default in several cases like "git status" and "git merge", so activating diff.renames does not fundamentally change the situation. When the rename detection fails, it now fails consistently between "git diff" and "git status". This setting does not affect plumbing commands, hence well-written scripts will not be affected.

2011-04-11Teach --dirstat not to completely ignore rearranged lines within a fileJohan Herland
Currently, the --dirstat analysis ignores when lines within a file are rearranged, because the "damage" calculated by show_dirstat() is 0. However, if the object name has changed, we already know that there is some damage, and it is unintuitive to claim there is _no_ damage. Teach show_dirstat() to assign a minimum amount of damage (== 1) to entries for which the analysis otherwise yields zero damage, to still represent that these files are changed, instead of saying that there is no change. Also, skip --dirstat analysis when the object names are the same (e.g. for a pure file rename).

2011-04-11--dirstat-by-file: Make it faster and more correctJohan Herland
Currently, when using --dirstat-by-file, it first does the full --dirstat analysis (using diffcore_count_changes()), and then resets 'damage' to 1, if any damage was found by diffcore_count_changes(). But --dirstat-by-file is not interested in the file damage per se. It only cares if the file changed at all. In that sense it only cares if the blob object for a file has changed. We therefore only need to compare the object names of each file pair in the diff queue and we can skip the entire --dirstat analysis and simply set 'damage' to 1 for each entry where the object name has changed. This makes --dirstat-by-file faster, and also bypasses --dirstat's practice of ignoring rearranged lines within a file. The patch also contains an added testcase verifying that --dirstat-by-file now detects changes that only rearrange lines within a file.

Traditionally, "show" defaulted to "show --cc" (dense combined patch), but asking for combined patch with "show -c" didn't turn the patch output format on; the placement of this logic in setup_revisions() dates back to cd2bdc5 (Common option parsing for "git log --diff" and friends, 2006-04-14). This unfortunately cannot be done as a trivial change of "if dense combined is asked, default to patch format" done in setup_revisions() to "if any combined is asked, default to patch format", as "diff-tree -c" needs to default to raw, while "diff-tree --cc" needs to default to patch, and they share the codepath. These command specific defaults are now handled in the new "tweak" callback that can be customized by individual command implementations. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-10-18format-patch: autonumber by defaultBrian Gernhardt
format-patch is most commonly used for multiple patches at once when sending a patchset, in which case we want to number the patches; on the other hand, single patches are not usually expected to be numbered. In other words, the typical behavior expected from format-patch is the one obtained by enabling autonumber, so we set it to be the default. Users that want to disable numbering for a particular patchset can do so with the existing -N command-line switch. Users that want to change the default behavior can use the format.numbering config key.

2008-10-12"git diff <tree>{3,}": do not reverse order of argumentsMatt McCutchen
According to the message of commit 0fe7c1de16f71312e6adac4b85bddf0d62a47168, "git diff" with three or more trees expects the merged tree first followed by the parents, in order. However, this command reversed the order of its arguments, resulting in confusing diffs. A comment /* Again, the revs are all reverse */ suggested there was a reason for this, but I can't figure out the reason, so I removed the reversal of the arguments. Test case included.

2008-08-17tests: use $TEST_DIRECTORY to refer to the t/ directoryJunio C Hamano
Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment. With this patch, and a one-liner not included here (because it would contradict with what Dscho really wants to do): | diff --git a/t/test-lib.sh b/t/test-lib.sh | index 70ea7e0..60e69e4 100644 | --- a/t/test-lib.sh | +++ b/t/test-lib.sh | @@ -485,7 +485,7 @@ fi | . ../GIT-BUILD-OPTIONS | | # Test repository | -test="trash directory" | +test="trash directory/another level/yet another" | rm -fr "$test" || { | trap - exit | echo >&5 "FATAL: Cannot prepare test area" all the tests still pass, but we would want extra sets of eyeballs on this type of change to really make sure.

2008-05-24"git diff": do not ignore index without --no-indexJunio C Hamano
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.

2008-05-24tests: do not use implicit "git diff --no-index"Junio C Hamano
As a general principle, we should not use "git diff" to validate the results of what git command that is being tested has done. We would not know if we are testing the command in question, or locating a bug in the cute hack of "git diff --no-index". Rather use test_cmp for that purpose.
