| Git v2.38 Release Notes |
| ======================= |
| |
| UI, Workflows & Features |
| |
| * "git remote show [-n] frotz" now pays attention to negative |
| pathspec. |
| |
| * "git push" sometimes performs poorly when reachability bitmaps are |
| used, even in a repository where other operations are helped by |
| bitmaps. The push.useBitmaps configuration variable is introduced |
| to allow disabling use of reachability bitmaps only for "git push". |
| |
| * "git grep -m<max-hits>" is a way to limit the hits shown per file. |
| |
| * "git merge-tree" learned a new mode where it takes two commits and |
| computes a tree that would result in the merge commit, if the |
| histories leading to these two commits were to be merged. |
| |
| * "git mv A B" in a sparsely populated working tree can be asked to |
| move a path between directories that are "in cone" (i.e. expected |
| to be materialized in the working tree) and "out of cone" |
| (i.e. expected to be hidden). The handling of such cases has been |
| improved. |
| |
| * Earlier, HTTP transport clients learned to tell the server side |
| what locale they are in by sending Accept-Language HTTP header, but |
| this was done only for some requests but not others. |
| |
| * Introduce a safe.barerepository configuration variable that |
| allows users to forbid discovery of bare repositories. |
| |
| * Various messages that come from the pack-bitmap codepaths have been |
| tweaked. |
| |
| * "git rebase -i" learns to update branches whose tip appear in the |
| rebased range with "--update-refs" option. |
| |
| * "git ls-files" learns the "--format" option to tweak its output. |
| |
| * "git cat-file" learned an option to use the mailmap when showing |
| commit and tag objects. |
| |
| * When "git merge" finds that it cannot perform a merge, it should |
| restore the working tree to the state before the command was |
| initiated, but in some corner cases it didn't. |
| |
| * Operating modes like "--batch" of "git cat-file" command learned to |
| take NUL-terminated input, instead of one-item-per-line. |
| |
| * "git rm" has become more aware of the sparse-index feature. |
| |
| * "git rev-list --disk-usage" learned to take an optional value |
| "human" to show the reported value in human-readable format, like |
| "3.40MiB". |
| |
| * The "diagnose" feature to create a zip archive for diagnostic |
| material has been lifted from "scalar" and made into a feature of |
| "git bugreport". |
| |
| * The namespaces used by "log --decorate" from "refs/" hierarchy by |
| default has been tightened. |
| |
| * "git rev-list --ancestry-path=C A..B" is a natural extension of |
| "git rev-list A..B"; instead of choosing a subset of A..B to those |
| that have ancestry relationship with A, it lets a subset with |
| ancestry relationship with C. |
| |
| * "scalar" now enables built-in fsmonitor on enlisted repositories, |
| when able. |
| |
| * The bash prompt (in contrib/) learned to optionally indicate when |
| the index is unmerged. |
| |
| * "git clone" command learned the "--bundle-uri" option to coordinate |
| with hosting sites the use of pre-prepared bundle files. |
| |
| * "git range-diff" learned to honor pathspec argument if given. |
| |
| * "git format-patch --from=<ident>" can be told to add an in-body |
| "From:" line even for commits that are authored by the given |
| <ident> with "--force-in-body-from" option. |
| |
| * The built-in fsmonitor refuses to work on a network mounted |
| repositories; a configuration knob for users to override this has |
| been introduced. |
| |
| * The "scalar" addition from Microsoft is now part of the core Git |
| installation. |
| |
| |
| Performance, Internal Implementation, Development Support etc. |
| |
| * Collection of what is referenced by objects in promisor packs have |
| been optimized to inspect these objects in the in-pack order. |
| |
| * Introduce a helper to see if a branch is already being worked on |
| (hence should not be newly checked out in a working tree), which |
| performs much better than the existing find_shared_symref() to |
| replace many uses of the latter. |
| |
| * Teach "git archive" to (optionally and then by default) avoid |
| spawning an external "gzip" process when creating ".tar.gz" (and |
| ".tgz") archives. |
| |
| * Allow large objects read from a packstream to be streamed into a |
| loose object file straight, without having to keep it in-core as a |
| whole. |
| |
| * Further preparation to turn git-submodule.sh into a builtin |
| continues. |
| |
| * Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp |
| macro, which would improve maintainability and readability. |
| |
| * Teach "make all" to build gitweb as well. |
| |
| * Tweak tests so that they still work when the "git init" template |
| did not create .git/info directory. |
| |
| * Add Coccinelle rules to detect the pattern of initializing and then |
| finalizing a structure without using it in between at all, which |
| happens after code restructuring and the compilers fail to |
| recognize as an unused variable. |
| |
| * The code to convert between GPG trust level strings and internal |
| constants we use to represent them have been cleaned up. |
| |
| * Support for libnettle as SHA256 implementation has been added. |
| |
| * The way "git multi-pack" uses parse-options API has been improved. |
| |
| * A Coccinelle rule (in contrib/) to encourage use of COPY_ARRAY |
| macro has been improved. |
| |
| * API tweak to make it easier to run fuzz testing on commit-graph parser. |
| |
| * Omit fsync-related trace2 entries when their values are all zero. |
| |
| * The codepath to write multi-pack index has been taught to release a |
| large chunk of memory that holds an array of objects in the packs, |
| as soon as it is done with the array, to reduce memory consumption. |
| |
| * Add a level of redirection to array allocation API in xdiff part, |
| to make it easier to share with the libgit2 project. |
| |
| * "git fetch" client logs the partial clone filter used in the trace2 |
| output. |
| |
| * The "bundle URI" design gets documented. |
| |
| * The common ancestor negotiation exchange during a "git fetch" |
| session now leaves trace log. |
| |
| * Test portability improvements. |
| (merge 4d1d843be7 mt/rot13-in-c later to maint). |
| |
| * The "subcommand" mode is introduced to parse-options API and update |
| the command line parser of Git commands with subcommands. |
| |
| * The pack bitmap file gained a bitmap-lookup table to speed up |
| locating the necessary bitmap for a given commit. |
| |
| * The assembly version of SHA-1 implementation for PPC has been |
| removed. |
| |
| * The server side that responds to "git fetch" and "git clone" |
| request has been optimized by allowing it to send objects in its |
| object store without recomputing and validating the object names. |
| |
| * Annotate function parameters that are not used (but cannot be |
| removed for structural reasons), to prepare us to later compile |
| with -Wunused warning turned on. |
| |
| * Share the text used to explain configuration variables used by "git |
| <subcmd>" in "git help <subcmd>" with the text from "git help config". |
| |
| * "git mv A B" in a sparsely populated working tree can be asked to |
| move a path from a directory that is "in cone" to another directory |
| that is "out of cone". Handling of such a case has been improved. |
| |
| * The chainlint script for our tests has been revamped. |
| |
| |
| Fixes since v2.37 |
| ----------------- |
| |
| * Rewrite of "git add -i" in C that appeared in Git 2.25 didn't |
| correctly record a removed file to the index, which was fixed. |
| |
| * Certain diff options are currently ignored when combined-diff is |
| shown; mark them as incompatible with the feature. |
| |
| * Adjust technical/bitmap-format to be formatted by AsciiDoc, and |
| add some missing information to the documentation. |
| |
| * Fixes for tests when the source directory has unusual characters in |
| its path, e.g. whitespaces, double-quotes, etc. |
| |
| * "git mktree --missing" lazily fetched objects that are missing from |
| the local object store, which was totally unnecessary for the purpose |
| of creating the tree object(s) from its input. |
| |
| * Give _() markings to fatal/warning/usage: labels that are shown in |
| front of these messages. |
| |
| * References to commands-to-be-typed-literally in "git rebase" |
| documentation mark-up have been corrected. |
| |
| * In a non-bare repository, the behavior of Git when the |
| core.worktree configuration variable points at a directory that has |
| a repository as its subdirectory, regressed in Git 2.27 days. |
| |
| * Recent update to vimdiff layout code has been made more robust |
| against different end-user vim settings. |
| |
| * Plug various memory leaks, both in the main code and in test-tool |
| commands. |
| |
| * Fixes a long-standing corner case bug around directory renames in |
| the merge-ort strategy. |
| |
| * The resolve-undo information in the index was not protected against |
| GC, which has been corrected. |
| |
| * A corner case bug where lazily fetching objects from a promisor |
| remote resulted in infinite recursion has been corrected. |
| |
| * "git clone" from a repository with some ref whose HEAD is unborn |
| did not set the HEAD in the resulting repository correctly, which |
| has been corrected. |
| |
| * An earlier attempt to plug leaks placed a clean-up label to jump to |
| at a bogus place, which as been corrected. |
| |
| * Variable quoting fix in the vimdiff driver of "git mergetool" |
| |
| * "git shortlog -n" relied on the underlying qsort() to be stable, |
| which shouldn't have. Fixed. |
| |
| * A fix for a regression in test framework. |
| |
| * mkstemp() emulation on Windows has been improved. |
| |
| * Add missing documentation for "include" and "includeIf" features in |
| "git config" file format, which incidentally teaches the command |
| line completion to include them in its offerings. |
| |
| * Avoid "white/black-list" in documentation and code comments. |
| |
| * Workaround for a compiler warning against use of die() in |
| osx-keychain (in contrib/). |
| |
| * Workaround for a false positive compiler warning. |
| |
| * "git p4" working on UTF-16 files on Windows did not implement |
| CRLF-to-LF conversion correctly, which has been corrected. |
| |
| * "git p4" did not handle non-ASCII client name well, which has been |
| corrected. |
| |
| * "rerere-train" script (in contrib/) used to honor commit.gpgSign |
| while recreating the throw-away merges. |
| |
| * "git checkout" miscounted the paths it updated, which has been |
| corrected. |
| |
| * Fix for a bug that makes write-tree to fail to write out a |
| non-existent index as a tree, introduced in 2.37. |
| |
| * There was a bug in the codepath to upgrade generation information |
| in commit-graph from v1 to v2 format, which has been corrected. |
| |
| * Gitweb had legacy URL shortener that is specific to the way |
| projects hosted on kernel.org used to (but no longer) work, which |
| has been removed. |
| |
| * Fix build procedure for Windows that uses CMake so that it can pick |
| up the shell interpreter from local installation location. |
| |
| * Conditionally allow building Python interpreter on Windows |
| |
| * Fix to lstat() emulation on Windows. |
| |
| * Older gcc with -Wall complains about the universal zero initializer |
| "struct s = { 0 };" idiom, which makes developers' lives |
| inconvenient (as -Werror is enabled by DEVELOPER=YesPlease). The |
| build procedure has been tweaked to help these compilers. |
| |
| * Plug memory leaks in the failure code path in the "merge-ort" merge |
| strategy backend. |
| |
| * "git symbolic-ref symref non..sen..se" is now diagnosed as an error. |
| |
| * A follow-up fix to a fix for a regression in 2.36 around hooks. |
| |
| * Avoid repeatedly running getconf to ask libc version in the test |
| suite, and instead just as it once per script. |
| |
| * Platform-specific code that determines if a directory is OK to use |
| as a repository has been taught to report more details, especially |
| on Windows. |
| |
| * "vimdiff3" regression fix. |
| |
| * "git fsck" reads mode from tree objects but canonicalizes the mode |
| before passing it to the logic to check object sanity, which has |
| hid broken tree objects from the checking logic. This has been |
| corrected, but to help existing projects with broken tree objects |
| that they cannot fix retroactively, the severity of anomalies this |
| code detects has been demoted to "info" for now. |
| |
| * Fixes to sparse index compatibility work for "reset" and "checkout" |
| commands. |
| |
| * An earlier optimization discarded a tree-object buffer that is |
| still in use, which has been corrected. |
| |
| * Fix deadlocks between main Git process and subprocess spawned via |
| the pipe_command() API, that can kill "git add -p" that was |
| reimplemented in C recently. |
| |
| * The sequencer machinery translated messages left in the reflog by |
| mistake, which has been corrected. |
| |
| * xcalloc(), imitating calloc(), takes "number of elements of the |
| array", and "size of a single element", in this order. A call that |
| does not follow this ordering has been corrected. |
| |
| * The preload-index codepath made copies of pathspec to give to |
| multiple threads, which were left leaked. |
| |
| * Update the version of Ubuntu used for GitHub Actions CI from 18.04 |
| to 22.04. |
| |
| * The auto-stashed local changes created by "git merge --autostash" |
| was mixed into a conflicted state left in the working tree, which |
| has been corrected. |
| |
| * Multi-pack index got corrupted when preferred pack changed from one |
| pack to another in a certain way, which has been corrected. |
| (merge 99e4d084ff tb/midx-with-changing-preferred-pack-fix later to maint). |
| |
| * The clean-up of temporary files created via mks_tempfile_dt() was |
| racy and attempted to unlink() the leading directory when signals |
| are involved, which has been corrected. |
| (merge babe2e0559 rs/tempfile-cleanup-race-fix later to maint). |
| |
| * FreeBSD portability fix for "git maintenance" that spawns "crontab" |
| to schedule tasks. |
| (merge ee69e7884e bc/gc-crontab-fix later to maint). |
| |
| * Those who use diff-so-fancy as the diff-filter noticed a regression |
| or two in the code that parses the diff output in the built-in |
| version of "add -p", which has been corrected. |
| (merge 0a101676e5 js/add-p-diff-parsing-fix later to maint). |
| |
| * Segfault fix-up to an earlier fix to the topic to teach "git reset" |
| and "git checkout" work better in a sparse checkout. |
| (merge 037f8ea6d9 vd/sparse-reset-checkout-fixes later to maint). |
| |
| * "git diff --no-index A B" managed its the pathnames of its two |
| input files rather haphazardly, sometimes leaking them. The |
| command line argument processing has been straightened out to clean |
| it up. |
| (merge 2b43dd0eb5 rs/diff-no-index-cleanup later to maint). |
| |
| * "git rev-list --verify-objects" ought to inspect the contents of |
| objects and notice corrupted ones, but it didn't when the commit |
| graph is in use, which has been corrected. |
| (merge b27ccae34b jk/rev-list-verify-objects-fix later to maint). |
| |
| * More fixes to "add -p" |
| (merge 64ec8efb83 js/builtin-add-p-portability-fix later to maint). |
| |
| * The parser in the script interface to parse-options in "git |
| rev-parse" has been updated to diagnose a bogus input correctly. |
| (merge f20b9c36d0 ow/rev-parse-parseopt-fix later to maint). |
| |
| * The code that manages list-object-filter structure, used in partial |
| clones, leaked the instances, which has been plugged. |
| (merge 66eede4a37 jk/plug-list-object-filter-leaks later to maint). |
| |
| * Fix another UI regression in the reimplemented "add -p". |
| (merge f6f0ee247f rs/add-p-worktree-mode-prompt-fix later to maint). |
| |
| * "git fetch" over protocol v2 sent an incorrect ref prefix request |
| to the server and made "git pull" with configured fetch refspec |
| that does not cover the remote branch to merge with fail, which has |
| been corrected. |
| (merge 49ca2fba39 jk/proto-v2-ref-prefix-fix later to maint). |
| |
| * A result from opendir() was leaking in the commit-graph expiration |
| codepath, which has been plugged. |
| (merge 12f1ae5324 ml/commit-graph-expire-dir-leak-fix later to maint). |
| |
| * Just like we have coding guidelines, we now have guidelines for |
| reviewers. |
| (merge e01b851923 vd/doc-reviewing-guidelines later to maint). |
| |
| * Other code cleanup, docfix, build fix, etc. |
| (merge 77b9e85c0f vd/fix-perf-tests later to maint). |
| (merge 0682bc43f5 jk/test-crontab-fixes later to maint). |
| (merge b46dd1726c cc/doc-trailer-whitespace-rules later to maint). |
