| Git 2.7 Release Notes |
| ===================== |
| |
| Updates since v2.6 |
| ------------------ |
| |
| UI, Workflows & Features |
| |
| * The appearance of "gitk", particularly on high DPI monitors, have |
| been improved. "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 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. |
| |
| * 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. |
