Use "--no-diff-merges" to restore the - previous behaviour to omit patches for merge commits. - - * The commit labels used to explain each side of conflicted hunks - placed by the sequencer machinery have been made more readable by - humans. - - * The "--batch-size" option of "git multi-pack-index repack" command - is now used to specify that very small packfiles are collected into - one until the total size roughly exceeds it. - - * The recent addition of SHA-256 support is marked as experimental in - the documentation. - - * "git fetch" learned --no-write-fetch-head option to avoid writing - the FETCH_HEAD file. - - * Command line completion (in contrib/) usually omits redundant, - deprecated and/or dangerous options from its output; it learned to - optionally include all of them. - - * The output from the "diff" family of the commands had abbreviated - object names of blobs involved in the patch, but its length was not - affected by the --abbrev option. Now it is. - - * "git worktree" gained a "repair" subcommand to help users recover - after moving the worktrees or repository manually without telling - Git. Also, "git init --separate-git-dir" no longer corrupts - administrative data related to linked worktrees. - - * The "--format=" option to the "for-each-ref" command and friends - learned a few more tricks, e.g. the ":short" suffix that applies to - "objectname" now also can be used for "parent", "tree", etc. - - * "git worktree add" learns that the "-d" is a synonym to "--detach" - option to create a new worktree without being on a branch. - - * "format-patch --range-diff=<prev> <origin>..HEAD" has been taught - not to ignore <origin> when <prev> is a single version. - - * "add -p" now allows editing paths that were only added in intent. - - * The 'meld' backend of the "git mergetool" learned to give the - underlying 'meld' the '--auto-merge' option, which would help - reduce the amount of text that requires manual merging. - - * "git for-each-ref" and friends that list refs used to allow only - one --merged or --no-merged to filter them; they learned to take - combination of both kind of filtering. - - * "git maintenance", a "git gc"'s big brother, has been introduced to - take care of more repository maintenance tasks, not limited to the - object database cleaning. - - * "git receive-pack" that accepts requests by "git push" learned to - outsource most of the ref updates to the new "proc-receive" hook. - - * "git push" that wants to be atomic and wants to send push - certificate learned not to prepare and sign the push certificate - when it fails the local check (hence due to atomicity it is known - that no certificate is needed). - - * "git commit-graph write" learned to limit the number of bloom - filters that are computed from scratch with the --max-new-filters - option. - - * The transport protocol v2 has become the default again. - - * The installation procedure learned to optionally omit "git-foo" - executable files for each 'foo' built-in subcommand, which are only - required by old timers that still rely on the age old promise that - prepending "git --exec-path" output to PATH early in their script - will keep the "git-foo" calls they wrote working. - - * The command line completion (in contrib/) learned that "git restore - -s <TAB>" is often followed by a refname. - - * "git shortlog" has been taught to group commits by the contents of - the trailer lines, like "Reviewed-by:", "Coauthored-by:", etc. - - * "git archive" learns the "--add-file" option to include untracked - files into a snapshot from a tree-ish. - - * "git fetch" and "git push" support negative refspecs. - - * "git format-patch" learns to take "whenAble" as a possible value - for the format.useAutoBase configuration variable to become no-op - when the automatically computed base does not make sense. - - * Credential helpers are now allowed to terminate lines with CRLF - line ending, as well as LF line ending. - - -Performance, Internal Implementation, Development Support etc. - - * The changed-path Bloom filter is improved using ideas from an - independent implementation. - - * Updates to the changed-paths bloom filter. - - * The test framework has been updated so that most tests will run - with predictable (artificial) timestamps. - - * Preliminary clean-up of the refs API in preparation for adding a - new refs backend "reftable". - - * Dev support to limit the use of test_must_fail to only git commands. - - * While packing many objects in a repository with a promissor remote, - lazily fetching missing objects from the promissor remote one by - one may be inefficient---the code now attempts to fetch all the - missing objects in batch (obviously this won't work for a lazy - clone that lazily fetches tree objects as you cannot even enumerate - what blobs are missing until you learn which trees are missing). - - * The pretend-object mechanism checks if the given object already - exists in the object store before deciding to keep the data - in-core, but the check would have triggered lazy fetching of such - an object from a promissor remote. - - * The argv_array API is useful for not just managing argv but any - "vector" (NULL-terminated array) of strings, and has seen adoption - to a certain degree. It has been renamed to "strvec" to reduce the - barrier to adoption. - - * The final leg of SHA-256 transition plus doc updates. Note that - there is no interoperability between SHA-1 and SHA-256 - repositories yet. - - * CMake support to build with MSVC for Windows bypassing the Makefile. - - * A new helper function has_object() has been introduced to make it - easier to mark object existence checks that do and don't want to - trigger lazy fetches, and a few such checks are converted using it. - - * A no-op replacement function implemented as a C preprocessor macro - does not perform as good a job as one implemented as a "static - inline" function in catching errors in parameters; replace the - former with the latter in <git-compat-util.h> header. - - * Test framework update. - (merge d572f52a64 es/test-cmp-typocatcher later to maint). - - * Updates to "git merge" tests, in preparation for a new merge - strategy backend. - - * midx and commit-graph files now use the byte defined in their file - format specification for identifying the hash function used for - object names. - - * The FETCH_HEAD is now always read from the filesystem regardless of - the ref backend in use, as its format is much richer than the - normal refs, and written directly by "git fetch" as a plain file.. - - * An unused binary has been discarded, and and a bunch of commands - have been turned into into built-in. - - * A handful of places in in-tree code still relied on being able to - execute the git subcommands, especially built-ins, in "git-foo" - form, which have been corrected. - - * When a packfile is removed by "git repack", multi-pack-index gets - cleared; the code was taught to do so less aggressively by first - checking if the midx actually refers to a pack that no longer - exists. - - * Internal API clean-up to handle two options "diff-index" and "log" - have, which happen to share the same short form, more sensibly. - - * The "add -i/-p" machinery has been written in C but it is not used - by default yet. It is made default to those who are participating - in feature.experimental experiment. - - * Allow maintainers to tweak $(TAR) invocations done while making - distribution tarballs. - - * "git index-pack" learned to resolve deltified objects with greater - parallelism. - - * "diff-highlight" (in contrib/) had a logic to flush its output upon - seeing a blank line but the way it detected a blank line was broken. - - * The logic to skip testing on the tagged commit and the tag itself - was not quite consistent which led to failure of Windows test - tasks. It has been revamped to consistently skip revisions that - have already been tested, based on the tree object of the revision. - - -Fixes since v2.28 ------------------ - - * The "mediawiki" remote backend which lives in contrib/mw-to-git/ - and is not built with git by default, had an RCE bug allowing a - malicious MediaWiki server operator to inject arbitrary commands - for execution by a cloning client. This has been fixed. - - The bug was discovered and reported by Joern Schneeweisz of GitLab - to the git-security mailing list. Its practical impact due to the - obscurity of git-remote-mediawiki was deemed small enough to forgo - a dedicated security release. - - * "git clone --separate-git-dir=$elsewhere" used to stomp on the - contents of the existing directory $elsewhere, which has been - taught to fail when $elsewhere is not an empty directory. - (merge dfaa209a79 bw/fail-cloning-into-non-empty later to maint). - - * With the base fix to 2.27 regresion, any new extensions in a v0 - repository would still be silently honored, which is not quite - right. Instead, complain and die loudly. - (merge ec91ffca04 jk/reject-newer-extensions-in-v0 later to maint). - - * Fetching from a lazily cloned repository resulted at the server - side in attempts to lazy fetch objects that the client side has, - many of which will not be available from the third-party anyway. - (merge 77aa0941ce jt/avoid-lazy-fetching-upon-have-check later to maint). - - * Fix to an ancient bug caused by an over-eager attempt for - optimization. - (merge a98f7fb366 rs/add-index-entry-optim-fix later to maint). - - * Pushing a ref whose name contains non-ASCII character with the - "--force-with-lease" option did not work over smart HTTP protocol, - which has been corrected. - (merge cd85b447bf bc/push-cas-cquoted-refname later to maint). - - * "git mv src dst", when src is an unmerged path, errored out - correctly but with an incorrect error message to claim that src is - not tracked, which has been clarified. - (merge 9b906af657 ct/mv-unmerged-path-error later to maint). - - * Fix to a regression introduced during 2.27 cycle. - (merge cada7308ad en/fill-directory-exponential later to maint). - - * Command line completion (in contrib/) update. - (merge 688b87c81b mp/complete-show-color-moved later to maint). - - * All "mergy" operations that internally use the merge-recursive - machinery should honor the merge.renormalize configuration, but - many of them didn't. - - * Doc cleanup around "worktree". - (merge dc9c144be5 es/worktree-doc-cleanups later to maint). - - * The "git blame --first-parent" option was not documented, but now - it is. - (merge 11bc12ae1e rp/blame-first-parent-doc later to maint). - - * The logic to find the ref transaction hook script attempted to - cache the path to the found hook without realizing that it needed - to keep a copied value, as the API it used returned a transitory - buffer space. This has been corrected. - (merge 09b2aa30c9 ps/ref-transaction-hook later to maint). - - * Recent versions of "git diff-files" shows a diff between the index - and the working tree for "intent-to-add" paths as a "new file" - patch; "git apply --cached" should be able to take "git diff-files" - and should act as an equivalent to "git add" for the path, but the - command failed to do so for such a path. - (merge 4c025c667e rp/apply-cached-with-i-t-a later to maint). - - * "git diff [<tree-ish>] $path" for a $path that is marked with i-t-a - bit was not showing the mode bits from the working tree. - (merge cb0dd22b82 rp/ita-diff-modefix later to maint). - - * Ring buffer with size 4 used for bin-hex translation resulted in a - wrong object name in the sequencer's todo output, which has been - corrected. - (merge 5da69c0dac ak/sequencer-fix-find-uniq-abbrev later to maint). - - * When given more than one target line ranges, "git blame -La,b - -Lc,d" was over-eager to coalesce groups of original lines and - showed incorrect results, which has been corrected. - (merge c2ebaa27d6 jk/blame-coalesce-fix later to maint). - - * The regexp to identify the function boundary for FORTRAN programs - has been updated. - (merge 75c3b6b2e8 pb/userdiff-fortran-update later to maint). - - * A few end-user facing messages have been updated to be - hash-algorithm agnostic. - (merge 4279000d3e jc/object-names-are-not-sha-1 later to maint). - - * "unlink" emulation on MinGW has been optimized. - (merge 680e0b4524 jh/mingw-unlink later to maint). - - * The purpose of "git init --separate-git-dir" is to initialize a - new project with the repository separate from the working tree, - or, in the case of an existing project, to move the repository - (the .git/ directory) out of the working tree. It does not make - sense to use --separate-git-dir with a bare repository for which - there is no working tree, so disallow its use with bare - repositories. - (merge ccf236a23a es/init-no-separate-git-dir-in-bare later to maint). - - * "ls-files -o" mishandled the top-level directory of another git - working tree that hangs in the current git working tree. - (merge ab282aa548 en/dir-nonbare-embedded later to maint). - - * Fix some incorrect UNLEAK() annotations. - (merge 3e19816dc0 jk/unleak-fixes later to maint). - - * Use more buffered I/O where we used to call many small write(2)s. - (merge a698d67b08 rs/more-buffered-io later to maint). - - * The patch-id computation did not ignore the "incomplete last line" - marker like whitespaces. - (merge 82a62015a7 rs/patch-id-with-incomplete-line later to maint). - - * Updates into a lazy/partial clone with a submodule did not work - well with transfer.fsckobjects set. - - * The parser for "git for-each-ref --format=..." was too loose when - parsing the "%(trailers...)" atom, and forgot that "trailers" and - "trailers:<modifiers>" are the only two allowed forms, which has - been corrected. - (merge 2c22e102f8 hv/ref-filter-trailers-atom-parsing-fix later to maint). - - * Long ago, we decided to use 3 threads by default when running the - index-pack task in parallel, which has been adjusted a bit upwards. - (merge fbff95b67f jk/index-pack-w-more-threads later to maint). - - * "git restore/checkout --no-overlay" with wildcarded pathspec - mistakenly removed matching paths in subdirectories, which has been - corrected. - (merge bfda204ade rs/checkout-no-overlay-pathspec-fix later to maint). - - * The description of --cached/--index options in "git apply --help" - has been updated. - (merge d064702be3 rp/apply-cached-doc later to maint). - - * Feeding "$ZERO_OID" to "git log --ignore-missing --stdin", and - running "git log --ignore-missing $ZERO_OID" fell back to start - digging from HEAD; it has been corrected to become a no-op, like - "git log --tags=no-tag-matches-this-pattern" does. - (merge 04a0e98515 jk/rev-input-given-fix later to maint). - - * Various callers of run_command API have been modernized. - (merge afbdba391e jc/run-command-use-embedded-args later to maint). - - * List of options offered and accepted by "git add -i/-p" were - inconsistent, which have been corrected. - (merge ce910287e7 pw/add-p-allowed-options-fix later to maint). - - * "git diff --stat -w" showed 0-line changes for paths whose changes - were only whitespaces, which was not intuitive. We now omit such - paths from the stat output. - (merge 1cf3d5db9b mr/diff-hide-stat-wo-textual-change later to maint). - - * It was possible for xrealloc() to send a non-NULL pointer that has - been freed, which has been fixed. - (merge 6479ea4a8a jk/xrealloc-avoid-use-after-free later to maint). - - * "git status" has trouble showing where it came from by interpreting - reflog entries that record certain events, e.g. "checkout @{u}", and - gives a hard/fatal error. Even though it inherently is impossible - to give a correct answer because the reflog entries lose some - information (e.g. "@{u}" does not record what branch the user was - on hence which branch 'the upstream' needs to be computed, and even - if the record were available, the relationship between branches may - have changed), at least hide the error and allow "status" to show its - output. - - * "git status --short" quoted a path with SP in it when tracked, but - not those that are untracked, ignored or unmerged. They are all - shown quoted consistently. - - * "git diff/show" on a change that involves a submodule used to read - the information on commits in the submodule from a wrong repository - and gave a wrong information when the commit-graph is involved. - (merge 85a1ec2c32 mf/submodule-summary-with-correct-repository later to maint). - - * Unlike "git config --local", "git config --worktree" did not fail - early and cleanly when started outside a git repository. - (merge 378fe5fc3d mt/config-fail-nongit-early later to maint). - - * There is a logic to estimate how many objects are in the - repository, which is meant to run once per process invocation, but - it ran every time the estimated value was requested. - (merge 67bb65de5d jk/dont-count-existing-objects-twice later to maint). - - * "git remote set-head" that failed still said something that hints - the operation went through, which was misleading. - (merge 5a07c6c3c2 cs/don-t-pretend-a-failed-remote-set-head-succeeded later to maint). - - * "git fetch --all --ipv4/--ipv6" forgot to pass the protocol options - to instances of the "git fetch" that talk to individual remotes, - which has been corrected. - (merge 4e735c1326 ar/fetch-ipversion-in-all later to maint). - - * The "unshelve" subcommand of "git p4" incorrectly used commit^N - where it meant to say commit~N to name the Nth generation - ancestor, which has been corrected. - (merge 0acbf5997f ld/p4-unshelve-fix later to maint). - - * "git clone" that clones from SHA-1 repository, while - GIT_DEFAULT_HASH set to use SHA-256 already, resulted in an - unusable repository that half-claims to be SHA-256 repository - with SHA-1 objects and refs. This has been corrected. - - * Adjust sample hooks for hash algorithm other than SHA-1. - (merge d8d3d632f4 dl/zero-oid-in-hooks later to maint). - - * "git range-diff" showed incorrect diffstat, which has been - corrected. - - * Earlier we taught "git pull" to warn when the user does not say the - histories need to be merged, rebased or accepts only fast- - forwarding, but the warning triggered for those who have set the - pull.ff configuration variable. - (merge 54200cef86 ah/pull later to maint). - - * Compilation fix around type punning. - (merge 176380fd11 jk/drop-unaligned-loads later to maint). - - * "git blame --ignore-rev/--ignore-revs-file" failed to validate - their input are valid revision, and failed to take into account - that the user may want to give an annotated tag instead of a - commit, which has been corrected. - (merge 610e2b9240 jc/blame-ignore-fix later to maint). - - * "git bisect start X Y", when X and Y are not valid committish - object names, should take X and Y as pathspec, but didn't. - (merge 73c6de06af cc/bisect-start-fix later to maint). - - * The explanation of the "scissors line" has been clarified. - (merge 287416dba6 eg/mailinfo-doc-scissors later to maint). - - * A race that leads to an access to a free'd data was corrected in - the codepath that reads pack files. - (merge bda959c476 mt/delta-base-cache-races later to maint). - - * in_merge_bases_many(), a way to see if a commit is reachable from - any commit in a set of commits, was totally broken when the - commit-graph feature was in use, which has been corrected. - (merge 8791bf1841 ds/in-merge-bases-many-optim-bug later to maint). - - * "git submodule update --quiet" did not squelch underlying "rebase" - and "pull" commands. - (merge 3ad0401e9e td/submodule-update-quiet later to maint). - - * The lazy fetching done internally to make missing objects available - in a partial clone incorrectly made permanent damage to the partial - clone filter in the repository, which has been corrected. - - * "log -c --find-object=X" did not work well to find a merge that - involves a change to an object X from only one parent. - (merge 957876f17d jk/diff-cc-oidfind-fix later to maint). - - * Other code cleanup, docfix, build fix, etc. - (merge 84544f2ea3 sk/typofixes later to maint). - (merge b17f411ab5 ar/help-guides-doc later to maint). - (merge 98c6871fad rs/grep-simpler-parse-object-or-die-call later to maint). - (merge 861c4ce141 en/typofixes later to maint). - (merge 60e47f6773 sg/ci-git-path-fix-with-pyenv later to maint). - (merge e2bfa50ac3 jb/doc-packfile-name later to maint). - (merge 918d8ff780 es/worktree-cleanup later to maint). - (merge dc156bc31f ma/t1450-quotefix later to maint). - (merge 56e743426b en/merge-recursive-comment-fixes later to maint). - (merge 7d23ff818f rs/bisect-oid-to-hex-fix later to maint). - (merge de20baf2c9 ny/notes-doc-sample-update later to maint). - (merge f649aaaf82 so/rev-parser-errormessage-fix later to maint). - (merge 6103d58b7f bc/sha-256-cvs-svn-updates later to maint). - (merge ac900fddb7 ma/stop-progress-null-fix later to maint). - (merge e767963ab6 rs/upload-pack-sigchain-fix later to maint). - (merge a831908599 rs/preserve-merges-unused-code-removal later to maint). - (merge 6dfefe70a9 jb/commit-graph-doc-fix later to maint). - (merge 847b37271e pb/set-url-docfix later to maint). - (merge 748f733d54 mt/checkout-entry-dead-code-removal later to maint). - (merge ce820cbd58 dl/subtree-docs later to maint). - (merge 55fe225dde jk/leakfix later to maint). - (merge ee22a29215 so/pretty-abbrev-doc later to maint). - (merge 3100fd5588 jc/post-checkout-doc later to maint). - (merge 17bae89476 pb/doc-external-diff-env later to maint). - (merge 27ed6ccc12 jk/worktree-check-clean-leakfix later to maint). - (merge 1302badd16 ea/blame-use-oideq later to maint). - (merge e6d5a11fed al/t3200-back-on-a-branch later to maint). - (merge 324efcf6b6 pw/add-p-leakfix later to maint). - (merge 1c6ffb546b jk/add-i-fixes later to maint). - (merge e40e936551 cd/commit-graph-doc later to maint). - (merge 0512eabd91 jc/sequencer-stopped-sha-simplify later to maint). - (merge d01141de5a so/combine-diff-simplify later to maint). - (merge 3be01e5ab1 sn/fast-import-doc later to maint). |
