Test coverage of "git replay" has + been improved. + + * The iconv library on macOS fails to correctly handle stateful + ISO/IEC 2022:1994 encoded strings. Work it around instead of + replacing it wholesale from homebrew. + + * Upstream symbolic link support on Windows from Git-for-Windows. + + +Performance, Internal Implementation, Development Support etc. +-------------------------------------------------------------- + + * The list of packfiles used in a running Git process is moved from + the packed_git structure into the packfile store. + + * Some ref backend storage can hold not just the object name of an + annotated tag, but the object name of the object the tag points at. + The code to handle this information has been streamlined. + + * As "git diff --quiet" only cares about the existence of any + changes, disable rename/copy detection to skip more expensive + processing whose result will be discarded anyway. + + * A part of code paths that deals with loose objects has been cleaned + up. + + * "make strip" has been taught to strip "scalar" as well as "git". + + * Dockerized jobs at the GitHub Actions CI have been taught to show + more details of failed tests. + + * Code refactoring around object database sources. + + * Halve the memory consumed by artificial filepairs created during + "git diff --find-copies-harder", also making the operation run + faster. + + * The "git_istream" abstraction has been revamped to make it easier + to interface with pluggable object database design. + + * Rewrite the only use of "mktemp()" that is subject to TOCTOU race + and Stop using the insecure "mktemp()" function. + (merge 10bba537c4 rs/ban-mktemp later to maint). + + * In-code comment update to clarify that single-letter options are + outside of the scope of command line completion script. + (merge dc8a00fafe jc/completion-no-single-letter-options later to maint). + + * MEMZERO_ARRAY() helper is introduced to avoid clearing only the + first N bytes of an N-element array whose elements are larger than + a byte. + + * "git diff-files -R --find-copies-harder" has been taught to use + the potential copy sources from the index correctly. + + * Require C99 style flexible array member support from all platforms. + + * The code path that enumerates promisor objects have been optimized + to skip pointlessly parsing blob objects. + + * Prepare test suite for Git for Windows that supports symbolic + links. + + * Import newer version of "clar", unit testing framework. + (merge 84071a6dea ps/clar-integers later to maint). + + * The packfile_store data structure is moved from object store to odb + source. + + * The object-info API has been cleaned up. + + * Further preparation to upstream symbolic link support on Windows. + + * Remove implicit reliance on the_repository global in the APIs + around tree objects and make it explicit which repository to work + in. + + * "git bugreport" and "git version --build-options" learned to + include use of 'gettext' feature, to make it easier to diagnose + problems around l10n. + + * Dscho observed that SVN tests are taking too much time in CI leak + checking tasks, but most time is spent not in our code but in libsvn + code (which happen to be written in Perl), whose leaks have little + value to discover for us. Skip SVN, P4, and CVS tests in the leak + checking tasks. + (merge 047bd7dfe3 js/ci-leak-skip-svn later to maint). + + +Fixes since v2.52 +----------------- + + * Ever since we added whitespace rules for this project, we misspelt + an entry, which has been corrected. + (merge 358e94dc70 jc/gitattributes-whitespace-no-indent-fix later to maint). + + * The code to expand attribute macros has been rewritten to avoid + recursion to avoid running out of stack space in an uncontrolled + way. + (merge 42ed046866 jk/attr-macroexpand-wo-recursion later to maint). + + * Adding a repository that uses a different hash function is a no-no, + but "git submodule add" did not prevent it, which has been corrected. + (merge 6fe288bfbc bc/submodule-force-same-hash later to maint). + + * An earlier check added to osx keychain credential helper to avoid + storing the credential itself supplied was overeager and rejected + credential material supplied by other helper backends that it would + have wanted to store, which has been corrected. + (merge 4580bcd235 kn/osxkeychain-idempotent-store-fix later to maint). + + * The "git repo structure" subcommand tried to align its output but + mixed up byte count and display column width, which has been + corrected. + (merge 7a03a10a3a jx/repo-struct-utf8width-fix later to maint). + + * Yet another corner case fix around renames in the "ort" merge + strategy. + (merge a562d90a35 en/ort-rename-another-fix later to maint). + + * Test leakfix. + (merge 14b561e768 jk/test-mktemp-leakfix later to maint). + + * Update a version of action used at the GitHub Actions CI. + (merge cd99203f86 js/ci-github-setup-go-update later to maint). + + * The "return errno = EFOO, -1" construct, which is heavily used in + compat/mingw.c and triggers warnings under "-Wcomma", has been + rewritten to avoid the warnings. + (merge af3919816f js/mingw-assign-comma-fix later to maint). + + * Makefile based build have recently been updated to build a + libgit.a that also has reftable and xdiff objects; CMake based + build procedure has been updated to match. + (merge b0d5c88cca js/cmake-libgit-fix later to maint). + + * Under-allocation fix. + (merge d22a488482 js/wincred-get-credential-alloc-fix later to maint). + + * "git worktree list" attempts to show paths to worktrees while + aligning them, but miscounted display columns for the paths when + non-ASCII characters were involved, which has been corrected. + (merge 08dfa59835 pw/worktree-list-display-width-fix later to maint). + + * "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. + (merge 17bd1108ea jk/ci-windows-meson-test-fix later to maint). + + * Emulation code clean-up. + (merge 2367c6bcd6 gf/win32-pthread-cond-wait-err later to maint). + + * Various issues detected by Asan have been corrected. + (merge a031b6181a jk/asan-bonanza later to maint). + + * "git config get --path" segfaulted on an ":(optional)path" that + does not exist, which has been corrected. + (merge 0bd16856ff jc/optional-path later to maint). + + * The "--committer-date-is-author-date" option of "git am/rebase" is + a misguided one. The documentation is updated to discourage its + use. + (merge fbf3d0669f kh/doc-committer-date-is-author-date later to maint). + + * The option help text given by "git config unset -h" described + the "--all" option to "replace", not "unset", multiple variables, + which has been corrected. + (merge 18bf67b753 rs/config-unset-opthelp-fix later to maint). + + * The error message given by "git config set", when the variable + being updated has more than one values defined, used old style "git + config" syntax with an incorrect option in its hint, both of which + have been corrected. + (merge df963f0df4 rs/config-set-multi-error-message-fix later to maint). + + * "git replay" forgot to omit the "gpgsig-sha256" extended header + from the resulting commit the same way it omits "gpgsig", which has + been corrected. + (merge 9f3a115087 pw/replay-exclude-gpgsig-fix later to maint). + + * A few tests have been updated to work under the shell compatible + mode of zsh. + (merge a92f243a94 bc/zsh-testsuite later to maint). + + * The way patience diff finds LCS has been optimized. + (merge c7e3b8085b yc/xdiff-patience-optim later to maint). + + * Recent optimization to "last-modified" command introduced use of + uninitialized block of memory, which has been corrected. + (merge fe4e60759b tc/last-modified-active-paths-optimization later to maint). + + * "git last-modified" used to mishandle "--" to mark the beginning of + pathspec, which has been corrected. + (merge 05491b90ce js/last-modified-with-sparse-checkouts later to maint). + + * Emulation code clean-up. + (merge 42aa7603aa gf/win32-pthread-cond-init later to maint). + + * "git submodule add" to add a submodule under <name> segfaulted, + when a submodule.<name>.something is already in

when a tag being fetched + needs to overwrite existing one, failed to fetch other tags, which + has been corrected. + (merge b7b17ec8a6 kn/fix-fetch-backfill-tag-with-batched-ref-updates later to maint). + + * Document "rev-list --filter-provided-objects" better. + (merge 6d8dc99478 jt/doc-rev-list-filter-provided-objects later to maint). + + * Even when there is no changes in the packfile and no need to + recompute bitmaps, "git repack" recomputed and updated the MIDX + file, which has been corrected. + (merge 6ce9d558ce ps/repack-avoid-noop-midx-rewrite later to maint). + + * Update HTTP tests to adjust for changes in curl 8.18.0 + (merge 17f4b01da7 jk/test-curl-updates later to maint). + + * Workaround the "iconv" shipped as part of macOS, which is broken + handling stateful ISO/IEC 2022 encoded strings. + (merge cee341e9dd rs/macos-iconv-workaround later to maint). + + * Running "git diff" with "--name-only" and other options that allows + us not to look at the blob contents, while objects that are lazily + fetched from a promisor remote, caused use-after-free, which has + been corrected. + + * The ort merge machinery hit an assertion failure in a history with + criss-cross merges renamed a directory and a non-directory, which + has been corrected. + (merge 979ee83e8a en/ort-recursive-d-f-conflict-fix later to maint). + + * Diagnose invalid bundle-URI that lack the URI entry, instead of + crashing. + (merge 7796c14a1a sb/bundle-uri-without-uri later to maint). + + * Mailmap update for Karsten + (merge e97678c4ef js/mailmap-karsten-blees later to maint).
