The command learned to take 'local' + as an instruction to use the local timezone with other formats, + + * The refs used during a "git bisect" session is now per-worktree so + that independent bisect sessions can be done in different worktrees + created with "git worktree add". + + * Users who are too busy to type three extra keystrokes to ask for + "git stash show -p" can now set stash.showPatch configuration + varible to true to always see the actual patch, not just the list + of paths affected with feel for the extent of damage via diffstat. + + * "quiltimport" allows to specify the series file by honoring the + $QUILT_SERIES environment and also --series command line option. + + * The use of 'good/bad' in "git bisect" made it confusing to use when + hunting for a state change that is not a regression (e.g. bugfix). + The command learned 'old/new' and then allows the end user to + say e.g. "bisect start --term-old=fast --term-new=slow" to find a + performance regression. + + * "git interpret-trailers" can now run outside of a Git repository. + + * "git p4" learned to reencode the pathname it uses to communicate + with the p4 depot with a new option. + + * Give progress meter to "git filter-branch". + + * Allow a later "!/abc/def" to override an earlier "/abc" that + appears in the same .gitignore file to make it easier to express + "everything in /abc directory is ignored, except for ...". + + * Teach "git p4" to send large blobs outside the repository by + talking to Git LFS. + + +Performance, Internal Implementation, Development Support etc. + + * The infrastructure to rewrite "git submodule" in C is being built + incrementally. Let's polish these early parts well enough and make + them graduate to 'next' and 'master', so that the more involved + follow-up can start cooking on a solid ground. + + * Some features from "git tag -l" and "git branch -l" have been made + available to "git for-each-ref" so that eventually the unified + implementation can be shared across all three. + + * Because "test_when_finished" in our test framework queues the + clean-up tasks to be done in a shell variable, it should not be + used inside a subshell. Add a mechanism to allow 'bash' to catch + such uses, and fix the ones that were found. + (merge 0968f12 jk/test-lint-forbid-when-finished-in-subshell later to maint). + + * The debugging infrastructure for pkt-line based communication has + been improved to mark the side-band communication specifically. + (merge fd89433 jk/async-pkt-line later to maint). + + * Update "git branch" that list existing branches, using the + ref-filter API that is shared with "git tag" and "git + for-each-ref". + + * The test for various line-ending conversions has been enhanced. + + * A few test scripts around "git p4" have been improved for + portability. + + * Many allocations that is manually counted (correctly) that are + followed by strcpy/sprintf have been replaced with a less error + prone constructs such as xstrfmt. + + +Also contains various documentation updates and code clean-ups. + + +Fixes since v2.6 +---------------- + +Unless otherwise noted, all the fixes since v2.6 in the maintenance +track are contained in this release (see the maintenance releases' +notes for details). + + * Very small number of options take a parameter that is optional + (which is not a great UI element as they can only appear at the end + of the command line). Add notice to documentation of each and + every one of them. + (merge 2b594bf mm/keyid-docs later to maint). + + * "git blame --first-parent v1.0..v2.0" was not rejected but did not + limit the blame to commits on the first parent chain. + (merge 95a4fb0 jk/blame-first-parent later to maint). + + * "git subtree" (in contrib/) now can take whitespaces in the + pathnames, not only in the in-tree pathname but the name of the + directory that the repository is in. (merge 5b6ab38 + as/subtree-with-spaces later to maint). + + * The ssh transport, just like any other transport over the network, + did not clear GIT_* environment variables, but it is possible to + use SendEnv and AcceptEnv to leak them to the remote invocation of + Git, which is not a good idea at all. Explicitly clear them just + like we do for the local transport. + (merge a48b409 jk/connect-clear-env later to maint). + + * Correct "git p4 --detect-labels" so that it does not fail to create + a tag that points at a commit that is also being imported. + (merge b43702a ld/p4-import-labels later to maint). + + * The Makefile always runs the library archiver with hardcoded "crs" + options, which was inconvenient for exotic platforms on which + people want to use programs with totally different set of command + line options. + (merge ac179b4 jw/make-arflags-customizable later to maint). + + * Customization to change the behaviour with "make -w" and "make -s" + in our Makefile was broken when they were used together. + (merge ef49e05 jk/make-findstring-makeflags-fix later to maint). + + * Allocation related functions and stdio are unsafe things to call + inside a signal handler, and indeed killing the pager can cause + glibc to deadlock waiting on allocation mutex as our signal handler + tries to free() some data structures in wait_for_pager(). Reduce + these unsafe calls. + (merge 507d780 ti/glibc-stdio-mutex-from-signal-handler later to maint). + + * The way how --ref/--notes to specify the notes tree reference are + DWIMmed was not clearly documented. + (merge e14c92e jk/notes-dwim-doc later to maint). + + * "git gc" used to barf when a symbolic ref has gone dangling + (e.g. the branch that used to be your upstream's default when you + cloned from it is now gone, and you did "fetch --prune"). + (merge 14886b4 js/gc-with-stale-symref later to maint). + + * "git clone --dissociate" runs a big "git repack" process at the + end, and it helps to close file descriptors that are open on the + packs and their idx files before doing so on filesystems that + cannot remove a file that is still open. + (merge 786b150 js/clone-dissociate later to maint). + + * Description of the "log.follow" configuration variable in "git log" + documentation is now also copied to "git config" documentation. + (merge fd8d07e dt/log-follow-config later to maint). + + * "git rebase -i" had a minor regression recently, which stopped + considering a line that begins with an indented '#' in its insn + sheet not a comment, which is now fixed. + (merge 1db168e gr/rebase-i-drop-warn later to maint). + + * After "git checkout --detach", "git status" reported a fairly + useless "HEAD detached at HEAD", instead of saying at which exact + commit. + (merge 0eb8548 mm/detach-at-HEAD-reflog later to maint). + + * When "git send-email" wanted to talk over Net::SMTP::SSL, + Net::Cmd::datasend() did not like to be fed too many bytes at the + same time and failed to send messages. Send the payload one line + at a time to work around the problem. + (merge f60c483 sa/send-email-smtp-batch-data-limit later to maint). + + * When "git am" was rewritten as a built-in, it stopped paying + attention to user.signingkey, which was fixed. + (merge 434c64d pt/am-builtin later to maint). + + * It was not possible to use a repository-lookalike created by "git + worktree add" as a local source of "git clone". + (merge d78db84 nd/clone-linked-checkout later to maint). + + * On a case insensitive filesystems, setting GIT_WORK_TREE variable + using a random cases that does not agree with what the filesystem + thinks confused Git that it wasn't inside the working tree. + (merge 63ec5e1 js/icase-wt-detection later to maint). + + * Performance-measurement tests did not work without an installed Git. + (merge 31cd128 sb/perf-without-installed-git later to maint). + + * A test script for the HTTP service had a timing dependent bug, + which was fixed. + (merge 362d8b6 sb/http-flaky-test-fix later to maint). + + * There were some classes of errors that "git fsck" diagnosed to its + standard error that did not cause it to exit with non-zero status. + (merge 122f76f jc/fsck-dropped-errors later to maint). + + * Work around "git p4" failing when the P4 depot records the contents + in UTF-16 without UTF-16 BOM. + (merge 1f5f390 ls/p4-translation-failure later to maint). + + * When "git gc --auto" is backgrounded, its diagnosis message is + lost. Save it to a file in $GIT_DIR and show it next time the "gc + --auto" is run. + (merge 329e6e8 nd/gc-auto-background-fix later to maint). + + * The submodule code has been taught to work better with separate + work trees created via "git worktree add". + (merge 11f9dd7 mk/submodule-gitdir-path later to maint). + + * "git gc" is safe to run anytime only because it has the built-in + grace period to protect young objects. In order to run with no + grace period, the user must make sure that the repository is + quiescent. + (merge fae1a90 jc/doc-gc-prune-now later to maint). + + * A recent "filter-branch --msg-filter" broke skipping of the commit + object header, which is fixed. + (merge a5a4b3f jk/filter-branch-use-of-sed-on-incomplete-line later to maint). + + * The normalize_ceiling_entry() function does not muck with the end + of the path it accepts, and the real world callers do rely on that, + but a test insisted that the function drops a trailing slash. + (merge b2a7123 rd/test-path-utils later to maint). + + * Code clean-up and minor fixes. + (merge 15ed07d jc/rerere later to maint). + (merge e7a7401 pt/pull-builtin later to maint). + (merge 29bc480 nd/ls-remote-does-not-have-u-option later to maint). + (merge be510e0 jk/asciidoctor-section-heading-markup-fix later to maint). + (merge 83e6bda tk/typofix-connect-unknown-proto-error later to maint). + (merge a43eb67 tk/doc-interpret-trailers-grammo later to maint). + (merge ba128e2 es/worktree-add-cleanup later to maint). + (merge 44cd91e cc/quote-comments later to maint). + (merge 147875f sb/submodule-config-parse later to maint). |
