The - command is taught to DWIM "--cc" (without "--raw" and other forms - of output specification) to "--cc -p -m". - - * "git config --list" output was hard to parse when values consist of - multiple lines. "--name-only" option is added to help this. - - * A handful of usability & cosmetic fixes to gitk and l10n updates. - - * A completely empty e-mail address <> is now allowed in the authors - file used by git-svn, to match the way it accepts the output from - authors-prog. - - -Performance, Internal Implementation, Development Support etc. - - * In preparation for allowing different "backends" to store the refs - in a way different from the traditional "one ref per file in - $GIT_DIR or in a $GIT_DIR/packed-refs file" filesystem storage, - direct filesystem access to ref-like things like CHERRY_PICK_HEAD - from scripts and programs has been reduced. - - * Computation of untracked status indicator by bash prompt - script (in contrib/) has been optimized. - - * Memory use reduction when commit-slab facility is used to annotate - sparsely (which is not recommended in the first place). - - * Clean up refs API and make "git clone" less intimate with the - implementation detail. - - * "git pull" was reimplemented in C. - - * The packet tracing machinery allows to capture an incoming pack - data to a file for debugging. - - * Move machinery to parse human-readable scaled numbers like 1k, 4M, - and 2G as an option parameter's value from pack-objects to - parse-options API, to make it available to other codepaths. - - * "git verify-tag" and "git verify-commit" have been taught to share - more code, and then learned to optionally show the verification - message from the underlying GPG implementation. - - * Various enhancements around "git am" reading patches generated by - foreign SCM have been made. - - * Ref listing by "git branch -l" and "git tag -l" commands has - started to be rebuilt, based on the for-each-ref machinery. - - * The code to perform multi-tree merges has been taught to repopulate - the cache-tree upon a successful merge into the index, so that - subsequent "diff-index --cached" (hence "status") and "write-tree" - (hence "commit") will go faster. - - The same logic in "git checkout" may now be removed, but that is a - separate issue. - - * Tests that assume how reflogs are represented on the filesystem too - much have been corrected. - - * "git am" has been rewritten in "C". - - * git_path() and mkpath() are handy helper functions but it is easy - to misuse, as the callers need to be careful to keep the number of - active results below 4. Their uses have been reduced. - - * The "lockfile" API has been rebuilt on top of a new "tempfile" API. - - * To prepare for allowing a different "ref" backend to be plugged in - to the system, update_ref()/delete_ref() have been taught about - ref-like things like MERGE_HEAD that are per-worktree (they will - always be written to the filesystem inside $GIT_DIR). - - * The gitmodules API that is accessed from the C code learned to - cache stuff lazily. - - -Also contains various documentation updates and code clean-ups. - - -Fixes since v2.5 ----------------- - -Unless otherwise noted, all the fixes since v2.5 in the maintenance -track are contained in this release (see the maintenance releases' -notes for details). - - * "git subtree" (in contrib/) depended on "git log" output to be - stable, which was a no-no. Apply a workaround to force a - particular date format. - (merge e7aac44 da/subtree-date-confusion later to maint). - - * An attempt to delete a ref by pushing into a repository whose HEAD - symbolic reference points at an unborn branch that cannot be - created due to ref D/F conflict (e.g. refs/heads/a/b exists, HEAD - points at refs/heads/a) failed. - (merge b112b14 jx/do-not-crash-receive-pack-wo-head later to maint). - - * The low-level "git send-pack" did not honor 'user.signingkey' - configuration variable when sending a signed-push. - (merge d830d39 db/send-pack-user-signingkey later to maint). - - * "sparse checkout" misbehaved for a path that is excluded from the - checkout when switching between branches that differ at the path. - (merge 7d78241 as/sparse-checkout-removal later to maint). - - * An experimental "untracked cache" feature used uname(2) in a - slightly unportable way. - (merge 100e433 cb/uname-in-untracked later to maint). - - * A "rebase" replays changes of the local branch on top of something - else, as such they are placed in stage #3 and referred to as - "theirs", while the changes in the new base, typically a foreign - work, are placed in stage #2 and referred to as "ours". Clarify - the "checkout --ours/--theirs". - (merge f303016 se/doc-checkout-ours-theirs later to maint). - - * The "rev-parse --parseopt" mode parsed the option specification - and the argument hint in a strange way to allow '=' and other - special characters in the option name while forbidding them from - the argument hint. This made it impossible to define an option - like "--pair <key>=<value>" with "pair=key=value" specification, - which instead would have defined a "--pair=key <value>" option. - (merge 2d893df ib/scripted-parse-opt-better-hint-string later to maint). - - * Often a fast-import stream builds a new commit on top of the - previous commit it built, and it often unconditionally emits a - "from" command to specify the first parent, which can be omitted in - such a case. This caused fast-import to forget the tree of the - previous commit and then re-read it from scratch, which was - inefficient. Optimize for this common case. - (merge 0df3245 mh/fast-import-optimize-current-from later to maint). - - * Running an aliased command from a subdirectory when the .git thing - in the working tree is a gitfile pointing elsewhere did not work. - (merge d95138e nd/export-worktree later to maint). - - * "Is this subdirectory a separate repository that should not be - touched?" check "git clean" was inefficient. This was replaced - with a more optimized check. - (merge fbf2fec ee/clean-remove-dirs later to maint). - - * The "new-worktree-mode" hack in "checkout" that was added in - nd/multiple-work-trees topic has been removed by updating the - implementation of new "worktree add". - (merge 65f9b75 es/worktree-add-cleanup later to maint). - - * Remove remaining cruft from "git checkout --to", which - transitioned to "git worktree add". - (merge 114ff88 es/worktree-add later to maint). - - * An off-by-one error made "git remote" to mishandle a remote with a - single letter nickname. - (merge bc598c3 mh/get-remote-group-fix later to maint). - - * "git clone $URL", when cloning from a site whose sole purpose is to - host a single repository (hence, no path after <scheme>://<site>/), - tried to use the site name as the new repository name, but did not - remove username or password when <site> part was of the form - <user>@<pass>:<host>. The code is taught to redact these. - (merge adef956 ps/guess-repo-name-at-root later to maint). - - * Running tests with the "-x" option to make them verbose had some - unpleasant interactions with other features of the test suite. - (merge 9b5fe78 jk/test-with-x later to maint). - - * t1509 test that requires a dedicated VM environment had some - bitrot, which has been corrected. - (merge faacc5a ps/t1509-chroot-test-fixup later to maint). - - * "git pull" in recent releases of Git has a regression in the code - that allows custom path to the --upload-pack=<program>. This has - been corrected. - - Note that this is irrelevant for 'master' with "git pull" rewritten - in C. - (merge 13e0e28 mm/pull-upload-pack later to maint). - - * When trying to see that an object does not exist, a state errno - leaked from our "first try to open a packfile with O_NOATIME and - then if it fails retry without it" logic on a system that refuses - O_NOATIME. This confused us and caused us to die, saying that the - packfile is unreadable, when we should have just reported that the - object does not exist in that packfile to the caller. - (merge dff6f28 cb/open-noatime-clear-errno later to maint). - - * The codepath to produce error messages had a hard-coded limit to - the size of the message, primarily to avoid memory allocation while - calling die(). - (merge f4c3edc jk/long-error-messages later to maint). - - * strbuf_read() used to have one extra iteration (and an unnecessary - strbuf_grow() of 8kB), which was eliminated. - (merge 3ebbd00 jh/strbuf-read-use-read-in-full later to maint). - - * We rewrote one of the build scripts in Perl but this reimplements - in Bourne shell. - (merge 57cee8a sg/help-group later to maint). - - * The experimental untracked-cache feature were buggy when paths with - a few levels of subdirectories are involved. - (merge 73f9145 dt/untracked-subdir later to maint). - - * "interpret-trailers" helper mistook a single-liner log message that - has a colon as the end of existing trailer. - - * The "interpret-trailers" helper mistook a multi-paragraph title of - a commit log message with a colon in it as the end of the trailer - block. - (merge 5c99995 cc/trailers-corner-case-fix later to maint). - - * "git describe" without argument defaulted to describe the HEAD - commit, but "git describe --contains" didn't. Arguably, in a - repository used for active development, such defaulting would not - be very useful as the tip of branch is typically not tagged, but it - is better to be consistent. - (merge 2bd0706 sg/describe-contains later to maint). - - * The client side codepaths in "git push" have been cleaned up - and the user can request to perform an optional "signed push", - i.e. sign only when the other end accepts signed push. - (merge 68c757f db/push-sign-if-asked later to maint). - - * Because the configuration system does not allow "alias.0foo" and - "pager.0foo" as the configuration key, the user cannot use '0foo' - as a custom command name anyway, but "git 0foo" tried to look these - keys up and emitted useless warnings before saying '0foo is not a - git command'. These warning messages have been squelched. - (merge 9e9de18 jk/fix-alias-pager-config-key-warnings later to maint). - - * "git rev-list" does not take "--notes" option, but did not complain - when one is given. - (merge 2aea7a5 jk/rev-list-has-no-notes later to maint). - - * When re-priming the cache-tree opportunistically while committing - the in-core index as-is, we mistakenly invalidated the in-core - index too aggressively, causing the experimental split-index code - to unnecessarily rewrite the on-disk index file(s). - (merge 475a344 dt/commit-preserve-base-index-upon-opportunistic-cache-tree-update later to maint). - - * "git archive" did not use zip64 extension when creating an archive - with more than 64k entries, which nobody should need, right ;-)? - (merge 88329ca rs/archive-zip-many later to maint). - - * The code in "multiple-worktree" support that attempted to recover - from an inconsistent state updated an incorrect file. - (merge 82fde87 nd/fixup-linked-gitdir later to maint). - - * On case insensitive systems, "git p4" did not work well with client - specs. - - * "git init empty && git -C empty log" said "bad default revision 'HEAD'", - which was found to be a bit confusing to new users. - (merge ce11360 jk/log-missing-default-HEAD later to maint). - - * Recent versions of scripted "git am" has a performance regression in - "git am --skip" codepath, which no longer exists in the built-in - version on the 'master' front. Fix the regression in the last - scripted version that appear in 2.5.x maintenance track and older. - (merge b9d6689 js/maint-am-skip-performance-regression later to maint). - - * The branch descriptions that are set with "git branch --edit-description" - option were used in many places but they weren't clearly documented. - (merge 561d2b7 po/doc-branch-desc later to maint). - - * Code cleanups and documentation updates. - (merge 1c601af es/doc-clean-outdated-tools later to maint). - (merge 3581304 kn/tag-doc-fix later to maint). - (merge 3a59e59 kb/i18n-doc later to maint). - (merge 45abdee sb/remove-unused-var-from-builtin-add later to maint). - (merge 14691e3 sb/parse-options-codeformat later to maint). - (merge 4a6ada3 ad/bisect-cleanup later to maint). - (merge da4c5ad ta/docfix-index-format-tech later to maint). - (merge ae25fd3 sb/check-return-from-read-ref later to maint). - (merge b3325df nd/dwim-wildcards-as-pathspecs later to maint). - (merge 7aa9b9b sg/wt-status-header-inclusion later to maint). - (merge f04c690 as/docfix-reflog-expire-unreachable later to maint). - (merge 1269847 sg/t3020-typofix later to maint). - (merge 8b54c23 jc/calloc-pathspec later to maint). - (merge a6926b8 po/po-readme later to maint). - (merge 54d160e ss/fix-config-fd-leak later to maint). - (merge b80fa84 ah/submodule-typofix-in-error later to maint). - (merge 99885bc ah/reflog-typofix-in-error later to maint). - (merge 9476c2c ah/read-tree-usage-string later to maint). - (merge b8c1d27 ah/pack-objects-usage-strings later to maint). - (merge 486e1e1 br/svn-doc-include-paths-config later to maint). - (merge 1733ed3 ee/clean-test-fixes later to maint). - (merge 5fcadc3 gb/apply-comment-typofix later to maint). - (merge b894d3e mp/t7060-diff-index-test later to maint). - (merge d238710 as/config-doc-markup-fix later to maint). |
