t: remove TEST_PASSES_SANITIZE_LEAK annotations

2024-11-20T23:23:48Z

Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there is no longer a need to have that variable declared in all of our tests. Drop it. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

userdiff: fix leaking memory for configured diff drivers

2024-08-14T17:08:01Z

The userdiff structures may be initialized either statically on the stack or dynamically via configuration keys. In the latter case we end up leaking memory because we didn't have any infrastructure to discern those strings which have been allocated statically and those which have been allocated dynamically. Refactor the code such that we have two pointers for each of these strings: one that holds the value as accessed by other subsystems, and one that points to the same string in case it has been allocated. Like this, we can safely free the second pointer and thus plug those memory leaks. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

tests: teach callers of test_i18ngrep to use test_grep

2023-11-02T08:13:44Z

They are equivalents and the former still exists, so as long as the only change this commit makes are to rewrite test_i18ngrep to test_grep, there won't be any new bug, even if there still are callers of test_i18ngrep remaining in the tree, or when merged to other topics that add new uses of test_i18ngrep. This patch was produced more or less with git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' | xargs perl -p -i -e 's/test_i18ngrep /test_grep /' and a good way to sanity check the result yourself is to run the above in a checkout of c4603c1c (test framework: further deprecate test_i18ngrep, 2023-10-31) and compare the resulting working tree contents with the result of applying this patch to the same commit. You'll see that test_i18ngrep in a few t/lib-*.sh files corrected, in addition to the manual reproduction. Signed-off-by: Junio C Hamano

attr: teach "--attr-source=" global option to "git"

2023-05-06T21:34:09Z

Earlier, 47cfc9bd (attr: add flag `--source` to work with tree-ish, 2023-01-14) taught "git check-attr" the "--source=" option to allow it to read attribute files from a tree-ish, but did so only for the command. Just like "check-attr" users wanted a way to use attributes from a tree-ish and not from the working tree files, users of other commands (like "git diff") would benefit from the same. Undo most of the UI change the commit made, while keeping the internal logic to read attributes from a given tree-ish. Expose the internal logic via a new "--attr-source=" command line option given to "git", so that it can be used with any git command that runs as part of the main git process. Additionally, add an environment variable GIT_ATTR_SOURCE that is set when --attr-source is passed in, so that subprocesses use the same value for the attributes source tree.

t4000-t4999: detect and signal failure within loop

2021-12-13T18:29:48Z

Failures within `for` and `while` loops can go unnoticed if not detected and signaled manually since the loop itself does not abort when a contained command fails, nor will a failure necessarily be detected when the loop finishes since the loop returns the exit code of the last command it ran on the final iteration, which may not be the command which failed. Therefore, detect and signal failures manually within loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

userdiff: remove support for "broken" tests

2021-04-08T19:19:10Z

There have been no "broken" tests since 75c3b6b2e8 (userdiff: improve Fortran xfuncname regex, 2020-08-12). Let's remove the test support for them. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

userdiff tests: list builtin drivers via test-tool

2021-04-08T19:19:10Z

Change the userdiff test to list the builtin drivers via the test-tool, using the new for_each_userdiff_driver() API function. This gets rid of the need to modify this part of the test every time a new pattern is added, see 2ff6c34612 (userdiff: support Bash, 2020-10-22) and 09dad9256a (userdiff: support Markdown, 2020-05-02) for two recent examples. I only need the "list-builtin-drivers "argument here, but let's add "list-custom-drivers" and "list-drivers" too, just because it's easy.

userdiff tests: explicitly test "default" pattern

2021-04-08T19:19:10Z

Since 122aa6f9c0 (diff: introduce diff..binary, 2008-10-05) the internals of the userdiff.c code have understood a "default" name, which is invoked as userdiff_find_by_name("default") and present in the "builtin_drivers" struct. Let's test for this special case. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

userdiff: support Bash

2020-10-22T17:29:30Z

Support POSIX, bashism and mixed function declarations, all four compound command types, trailing comments and mixed whitespace. Even though Bash allows locale-dependent characters in function names , only detect function names with characters allowed by POSIX.1-2017 for simplicity. This should cover the vast majority of use cases, and produces system-agnostic results. Since a word pattern has to be specified, but there is no easy way to know the default word pattern, use the default `IFS` characters for a starter. A later patch can improve this.

userdiff: support Markdown

2020-05-03T01:04:12Z

It's typical to find Markdown documentation alongside source code, and having better context for documentation changes is useful; see also commit 69f9c87d4 (userdiff: add support for Fountain documents, 2015-07-21). The pattern is based on the CommonMark specification 0.29, section 4.2 but doesn't match empty headings, as seeing them in a hunk header is unlikely to be useful. Only ATX headings are supported, as detecting setext headings would require printing the line before a pattern matches, or matching a multiline pattern. The word-diff pattern is the same as the pattern for HTML, because many Markdown parsers accept inline HTML. Signed-off-by: Ash Holland Acked-by: Johannes Sixt Signed-off-by: Junio C Hamano
