"gitk" also comes with an undated translation for - Swedish and Japanese. - - * "git remote" learned "get-url" subcommand to show the URL for a - given remote name used for fetching and pushing. - - * There was no way to defeat a configured rebase.autostash variable - from the command line, as "git rebase --no-autostash" was missing. - - * "git log --date=local" used to only show the normal (default) - format in the local timezone. 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 - variable 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 re-encode 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. - - * Prepare for Git on-disk repository representation to undergo - backward incompatible changes by introducing a new repository - format version "1", with an extension mechanism. - - * "git worktree" learned a "list" subcommand. - - * "git clone --dissociate" learned that it can be used even when - "--reference" was not used at the same time. - - * "git blame" learnt to take "--first-parent" and "--reverse" at the - same time when it makes sense. - - * "git checkout" did not follow the usual "--[no-]progress" - convention and implemented only "--quiet" that is essentially - a superset of "--no-progress". Extend the command to support the - usual "--[no-]progress". - - * The semantics of transfer.hideRefs configuration variable have been - extended to work better with the ref "namespace" feature that lets - you throw unrelated bunches of repositories in a single physical - repository and virtually serve them as separate ones. - - * send-email config variables whose values are pathnames now go - through the ~username/ expansion. - - * bash completion learnt to TAB-complete recipient addresses given - to send-email. - - * The credential-cache daemon can be told to ignore SIGHUP to work - around issue when running Git from inside emacs. - - * "git push" learned new configuration for doing "--recurse-submodules" - on each push. - - * "format-patch" has learned a new option to zero-out the commit - object name on the mbox "From " line. - - -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. The version merged - to the 'master' branch earlier had a performance regression in "tag - --contains", which has since been corrected. - - * 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. - - * The debugging infrastructure for pkt-line based communication has - been improved to mark the side-band communication specifically. - - * 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. - - * The internal stripspace() function has been moved to where it - logically belongs to, i.e. strbuf API, and the command line parser - of "git stripspace" has been updated to use the parse_options API. - - * "git am" used to spawn "git mailinfo" via run_command() API once - per each patch, but learned to make a direct call to mailinfo() - instead. - - * The implementation of "git mailinfo" was refactored so that a - mailinfo() function can be directly called from inside a process. - - * With a "debug" helper, debugging of a single "git" invocation in - our test scripts has become a lot easier. - - * The "configure" script did not test for -lpthread correctly, which - upset some linkers. - - * Cross completed task off of subtree project's todo list. - - * Test cleanups for the subtree project. - - * Clean up style in an ancient test t9300. - - * Work around some test flakiness with p4d. - - * Fsck did not correctly detect a NUL-truncated header in a tag. - - * Use a safer behavior when we hit errors verifying remote certificates. - - * Speed up filter-branch for cases where we only care about rewriting - commits, not tree data. - - * The parse-options API has been updated to make "-h" command line - option work more consistently in all commands. - - * "git svn rebase/mkdirs" got optimized by keeping track of empty - directories better. - - * Fix some racy client/server tests by treating SIGPIPE the same as a - normal non-zero exit. - - * The necessary infrastructure to build topics using the free Travis - CI has been added. Developers forking from this topic (and enabling - Travis) can do their own builds, and we can turn on auto-builds for - git/git (including build-status for pull requests that people - open). - - * The write(2) emulation for Windows learned to set errno to EPIPE - when necessary. - - -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. - - * "git blame --first-parent v1.0..v2.0" was not rejected but did not - limit the blame to commits on the first parent chain. - - * "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. - - * 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. - - * 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. - - * 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. - - * Customization to change the behaviour with "make -w" and "make -s" - in our Makefile was broken when they were used together. - - * 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. - - * The way how --ref/--notes to specify the notes tree reference are - DWIMmed was not clearly documented. - - * "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"). - - * "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. - - * Description of the "log.follow" configuration variable in "git log" - documentation is now also copied to "git config" documentation. - - * "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. Further, the code was still too picky on - Windows where CRLF left by the editor is turned into a trailing CR - on the line read via the "read" built-in command of bash. Both of - these issues are now fixed. - - * After "git checkout --detach", "git status" reported a fairly - useless "HEAD detached at HEAD", instead of saying at which exact - commit. - - * 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. - - * When "git am" was rewritten as a built-in, it stopped paying - attention to user.signingkey, which was fixed. - - * It was not possible to use a repository-lookalike created by "git - worktree add" as a local source of "git clone". - - * 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. - - * Performance-measurement tests did not work without an installed Git. - - * A test script for the HTTP service had a timing dependent bug, - which was fixed. - - * 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. - - * Work around "git p4" failing when the P4 depot records the contents - in UTF-16 without UTF-16 BOM. - - * 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. - - * The submodule code has been taught to work better with separate - work trees created via "git worktree add". - - * "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. - - * A recent "filter-branch --msg-filter" broke skipping of the commit - object header, which is fixed. - - * 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. - - * A test for interaction between untracked cache and sparse checkout - added in Git 2.5 days were flaky. - - * A couple of commands still showed "[options]" in their usage string - to note where options should come on their command line, but we - spell that "[<options>]" in most places these days. - - * The synopsis text and the usage string of subcommands that read - list of things from the standard input are often shown as if they - only take input from a file on a filesystem, which was misleading. - - * "git am -3" had a small regression where it is aborted in its error - handling codepath when underlying merge-recursive failed in certain - ways, as it assumed that the internal call to merge-recursive will - never die, which is not the case (yet). - - * The linkage order of libraries was wrong in places around libcurl. - - * The name-hash subsystem that is used to cope with case insensitive - filesystems keeps track of directories and their on-filesystem - cases for all the paths in the index by holding a pointer to a - randomly chosen cache entry that is inside the directory (for its - ce->ce_name component). This pointer was not updated even when the - cache entry was removed from the index, leading to use after free. - This was fixed by recording the path for each directory instead of - borrowing cache entries and restructuring the API somewhat. - - * "git merge-file" tried to signal how many conflicts it found, which - obviously would not work well when there are too many of them. - - * The error message from "git blame --contents --reverse" incorrectly - talked about "--contents --children". - - * "git imap-send" did not compile well with older version of cURL library. - - * Merging a branch that removes a path and another that changes the - mode bits on the same path should have conflicted at the path, but - it didn't and silently favoured the removal. - - * "git --literal-pathspecs add -u/-A" without any command line - argument misbehaved ever since Git 2.0. - - * "git daemon" uses "run_command()" without "finish_command()", so it - needs to release resources itself, which it forgot to do. - - * "git status --branch --short" accessed beyond the constant string - "HEAD", which has been corrected. - - * We peek objects from submodule's object store by linking it to the - list of alternate object databases, but the code to do so forgot to - correctly initialize the list. - - * The code to prepare the working tree side of temporary directory - for the "dir-diff" feature forgot that symbolic links need not be - copied (or symlinked) to the temporary area, as the code already - special cases and overwrites them. Besides, it was wrong to try - computing the object name of the target of symbolic link, which may - not even exist or may be a directory. - - * A Range: request can be responded with a full response and when - asked properly libcurl knows how to strip the result down to the - requested range. However, we were hand-crafting a range request - and it did not kick in. - - * Having a leftover .idx file without corresponding .pack file in - the repository hurts performance; "git gc" learned to prune them. - - * Apple's common crypto implementation of SHA1_Update() does not take - more than 4GB at a time, and we now have a compile-time workaround - for it. - - * Produce correct "dirty" marker for shell prompts, even when we - are on an orphan or an unborn branch. - - * A build without NO_IPv6 used to use gethostbyname() when guessing - user's hostname, instead of getaddrinfo() that is used in other - codepaths in such a build. - - * The exit code of git-fsck did not reflect some types of errors - found in packed objects, which has been corrected. - - * The helper used to iterate over loose object directories to prune - stale objects did not closedir() immediately when it is done with a - directory--a callback such as the one used for "git prune" may want - to do rmdir(), but it would fail on open directory on platforms - such as WinXP. - - * "git p4" used to import Perforce CLs that touch only paths outside - the client spec as empty commits. It has been corrected to ignore - them instead, with a new configuration git-p4.keepEmptyCommits as a - backward compatibility knob. - - * The completion script (in contrib/) used to list "git column" - (which is not an end-user facing command) as one of the choices - (merge 160fcdb sg/completion-no-column later to maint). - - * The error reporting from "git send-email", when SMTP TLS fails, has - been improved. - (merge 9d60524 jk/send-email-ssl-errors later to maint). - - * When getpwuid() on the system returned NULL (e.g. the user is not - in the /etc/passwd file or other uid-to-name mappings), the - codepath to find who the user is to record it in the reflog barfed - and died. Loosen the check in this codepath, which already accepts - questionable ident string (e.g. host part of the e-mail address is - obviously bogus), and in general when we operate fmt_ident() function - in non-strict mode. - (merge 92bcbb9 jk/ident-loosen-getpwuid later to maint). - - * "git symbolic-ref" forgot to report a failure with its exit status. - (merge f91b273 jk/symbolic-ref-maint later to maint). - - * History traversal with "git log --source" that starts with an - annotated tag failed to report the tag as "source", due to an - old regression in the command line parser back in v2.2 days. - (merge 728350b jk/pending-keep-tag-name later to maint). - - * "git p4" when interacting with multiple depots at the same time - used to incorrectly drop changes. - - * Code clean-up, minor fixes etc. |
