ci: ensure full sanitizer logs are shown in CI #39361

2026-04-25T14:33:39Z

Problem: When ASAN detects an error in a child process, the process may be killed by test teardown before ASAN finishes writing its log file. This results in truncated logs with no stack trace. Also, the sanitizer log content was only written to stdout (which the test runner may not display) and not included in the test_assert error message. Solution: - Poll (up to 2s) for the ASAN "SUMMARY" line before reading, so the crashing process has time to finish writing. - Include full log content in the test_assert error message, so it appears in CI output regardless of stdout handling. - Warn when the log appears truncated (no SUMMARY line found).

ci: drop cirrus #39321

2026-04-22T22:25:07Z

Problem: cirrus will shutdown soon, and we are running out of minutes anyway, which causes ci failures. Solution: Drop cirrus config.

test: replace busted with local harness

2026-04-15T11:09:25Z

Replace the busted-based Lua test runner with a repo-local harness. The new harness runs spec files directly under `nvim -ll`, ships its own reporter and lightweight `luassert` shim, and keeps the helper/preload flow used by the functional and unit test suites. Keep the file boundary model shallow and busted-like by restoring `_G`, `package.loaded`, `package.preload`, `arg`, and the process environment between files, without carrying extra reset APIs or custom assertion machinery. Update the build and test entrypoints to use the new runner, add black-box coverage for the harness itself, and drop the bundled busted/luacheck dependency path. AI-assisted: Codex

test: fix s390x failures

2026-03-29T11:36:56Z

Problem: failures in s390x CI. Solution: - runtime/lua/man.lua: parse_path() can return nil but 3 callers didn't handle it. - skip some tests on s390x.

test: fs_spec fails if home is a symlink #38258

feat(logging): rename ".nvimlog" => "nvim.log" #37935

2026-02-18T16:58:34Z

- Rename ".nvimlog" to "nvim.log" - doesn't need to be "hidden"/dotfile - ".log" extension helps with filetype detection - Also rename "nvim/log" => "nvim/nvim.log"

fix(terminal): changing height may lead to wrong scrollback (#37824)

2026-02-12T12:10:02Z

Problem: Changing terminal height immediately after outputting lines may lead to wrong scrollback. Solution: Insert pending scrollback lines before the old window height.

test: fix some type warnings (#37483)

fix(tests): use uv.spawn instead of io.popen for unittest helpers

2025-05-22T09:56:46Z

The old implementation of repeated_read_cmd would attempt to run the command multiple times to handle racyness of async output. Code like this should not be written. Instead, use the libuv event loop to read until the process has exited and the pipe has been closed. This causes some previous discarded errors to be propagated. Fix these as well.
