t/unit-tests: demonstrate use of integer comparison assertions

2025-12-06T22:25:16Z

The clar project has introduced a couple of new assertions that perform relative integer comparisons, like "greater than" or "less or equal". Adapt the reftable-record unit tests to demonstrate their usage. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

t/unit-tests: update clar to 39f11fe

2025-12-06T22:25:15Z

Update clar to commit 39f11fe (Merge pull request #131 from pks-gitlab/pks-integer-double-evaluation, 2025-12-05). This commit includes the following changes relevant to Git: - There are now typesafe integer comparison functions. Furthermore, the range of comparison functions has been included to also have relative comparisons, like "greater than". - There is a new `cl_failf()` macro that allows the caller to specify an error message with formatting directives. - The TAP format has been fixed to correctly terminate YAML blocks with "...\n" instead of "---\n". Note that we already had a `cl_failf()` function declared in our own sources. This function is equivalent to the upstreamed function, so we can simply drop it now.

Merge branch 'jk/ci-windows-meson-test-fix'

2025-11-26T18:32:43Z

"Windows+meson" job at the GitHub Actions CI was hard to debug, as it did not show and save failed test artifacts, which has been corrected. * jk/ci-windows-meson-test-fix: ci(windows-meson-test): handle options and output like other test jobs unit-test: ignore --no-chain-lint

Merge branch 'jx/repo-struct-utf8width-fix'

2025-11-24T23:46:41Z

The "git repo structure" subcommand tried to align its output but mixed up byte count and display column width, which has been corrected. * jx/repo-struct-utf8width-fix: builtin/repo: fix table alignment for UTF-8 characters t/unit-tests: add UTF-8 width tests for CJK chars

unit-test: ignore --no-chain-lint

2025-11-18T17:45:28Z

In the same spirit as 9faf3963b6 (t: introduce compatibility options to clar-based tests, 2024-12-13), we should ignore --no-chain-lint passed to our clar tests, since it may appear in GIT_TEST_OPTS to be used with other tests. This is particularly important on Windows CI, where --no-chain-lint is added to the test options by default, and the meson build will pass all options to the unit tests. The only reason our meson Windows CI job does not run into this currently is that it is not respecting GIT_TEST_OPTS at all! So ignoring this option is a prerequisite to fixing that situation.

builtin/repo: fix table alignment for UTF-8 characters

2025-11-17T00:04:24Z

The output table from "git repo structure" is misaligned when displaying UTF-8 characters (e.g., non-ASCII glyphs). E.g.: | 仓库结构 | 值 | | -------------- | ---- | | * 引用 | | | * 计数 | 67 | The previous implementation used simple width formatting with printf() which didn't properly handle multi-byte UTF-8 characters, causing misaligned table columns when displaying repository structure information. This change modifies the stats_table_print_structure function to use strbuf_utf8_align() instead of basic printf width specifiers. This ensures proper column alignment regardless of the character encoding of the content being displayed. Also add test cases for strbuf_utf8_align(), a function newly introduced in "builtin/repo.c".

t/unit-tests: add UTF-8 width tests for CJK chars

2025-11-17T00:04:24Z

The file "builtin/repo.c" uses utf8_strwidth() to calculate the display width of UTF-8 characters in a table, but the resulting output is still misaligned. Add test cases for both utf8_strwidth and utf8_strnwidth to verify that they correctly compute the display width for UTF-8 characters. Also updated the build configuration in Makefile and meson.build to include the new test suite in the build process. Signed-off-by: Jiang Xin Signed-off-by: Junio C Hamano

reftable/stack: add function to check if optimization is required

2025-11-10T17:28:47Z

The reftable backend performs auto-compaction as part of its regular flow, which is required to keep the number of tables part of a stack at bay. This allows it to stay optimized. Compaction can also be triggered voluntarily by the user via the 'git pack-refs' or the 'git refs optimize' command. However, currently there is no way for the user to check if optimization is required without actually performing it. Extract out the heuristics logic from 'reftable_stack_auto_compact()' into an internal function 'update_segment_if_compaction_required()'. Then use this to add and expose `reftable_stack_compaction_required()` which will allow users to check if the reftable backend can be optimized.
