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 discovery.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. + + +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. + + +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. + (merge ece3974ba6 ab/leakfix later to maint). + + * Plug various memory leaks in test-tool commands. + (merge f40a693450 ab/test-tool-leakfix later to maint). + + * 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. + (merge e0ad13977a jc/resolve-undo later to maint). + + * A corner case bug where lazily fetching objects from a promisor + remote resulted in infinite recursion has been corrected. + (merge cb88b37cb9 hx/lookup-commit-in-graph-fix later to maint). + + * "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. + (merge daf7898abb jk/clone-unborn-confusion later to maint). + + * 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. + (merge ae25974de3 rs/mingw-tighten-mkstemp later to maint). + + * 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. + (merge 07aed58017 mb/config-document-include later to maint). + + * Avoid "white/black-list" in documentation and code comments. + (merge f5adaa5cc3 ds/doc-wo-whitelist later to maint). + + * Workaround for a compiler warning against use of die() in + osx-keychain (in contrib/). + (merge f2fc531585 ld/osx-keychain-usage-fix later to maint). + + * Workaround for a false positive compiler warning. + (merge b4f52f09ae ds/win-syslog-compiler-fix later to maint). + + * "git p4" working on UTF-16 files on Windows did not implement + CRLF-to-LF conversion correctly, which has been corrected. + (merge 4d35f74421 mb/p4-utf16-crlf later to maint). + + * "git p4" did not handle non-ASCII client name well, which has been + corrected. + (merge d205483695 kk/p4-client-name-encoding-fix later to maint). + + * "rerere-train" script (in contrib/) used to honor commit.gpgSign + while recreating the throw-away merges. + (merge cc391fc886 cl/rerere-train-with-no-sign later to maint). + + * "git checkout" miscounted the paths it updated, which has been + corrected. + (merge 611c7785e8 mt/checkout-count-fix later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge a700395eaf ma/t4200-update later to maint). + (merge ae436f283c ma/sparse-checkout-cone-doc-fix later to maint). + (merge a10f6e2bda sg/index-format-doc-update later to maint). + (merge ce5f07983d mt/pkt-line-comment-tweak later to maint). |
