The code now sanitizes the names + given to worktrees, to make sure these refs are well-formed. + + * "git merge" learned "--quit" option that cleans up the in-progress + merge while leaving the working tree and the index still in a mess. + + * "git format-patch" learns a configuration to set the default for + its --notes=<ref> option. + + * The code to show args with potential typo that cannot be + interpreted as a commit-ish has been improved. + + * "git clone --recurse-submodules" learned to set up the submodules + to ignore commit object names recorded in the superproject gitlink + and instead use the commits that happen to be at the tip of the + remote-tracking branches from the get-go, by passing the new + "--remote-submodules" option. + + * The pattern "git diff/grep" use to extract funcname and words + boundary for Matlab has been extend to cover Octave, which is more + or less equivalent. + + * "git help git" was hard to discover (well, at least for some + people). + + * The pattern "git diff/grep" use to extract funcname and words + boundary for Rust has been added. + + * "git status" can be told a non-standard default value for the + "--[no-]ahead-behind" option with a new configuration variable + status.aheadBehind. + + * "git fetch" and "git pull" reports when a fetch results in + non-fast-forward updates to let the user notice unusual situation. + The commands learned "--no-show-forced-updates" option to disable + this safety feature. + + * Two new commands "git switch" and "git restore" are introduced to + split "checking out a branch to work on advancing its history" and + "checking out paths out of the index and/or a tree-ish to work on + advancing the current history" out of the single "git checkout" + command. + + * "git branch --list" learned to always output the detached HEAD as + the first item (when the HEAD is detached, of course), regardless + of the locale. + + * The conditional inclusion mechanism learned to base the choice on + the branch the HEAD currently is on. + + * "git rev-list --objects" learned the "--no-object-names" option to + squelch the path to the object that is used as a grouping hint for + pack-objects. + + * A new tag.gpgSign configuration variable turns "git tag -a" into + "git tag -s". + + * "git multi-pack-index" learned expire and repack subcommands. + + * "git blame" learned to "ignore" commits in the history, whose + effects (as well as their presence) get ignored. + + * "git cherry-pick/revert" learned a new "--skip" action. + + * The tips of refs from the alternate object store can be used as + starting point for reachability computation now. + + * Extra blank lines in "git status" output have been reduced. + + * The commits in a repository can be described by multiple + commit-graph files now, which allows the commit-graph files to be + updated incrementally. + + * "git range-diff" output has been tweaked for easier identification + of which part of what file the patch shown is about. + + +Performance, Internal Implementation, Development Support etc. + + * Update supporting parts of "git rebase" to remove code that should + no longer be used. + + * Developer support to emulate unsatisfied prerequisites in tests to + ensure that the remainder of the tests still succeeds when tests + with prerequisites are skipped. + + * "git update-server-info" learned not to rewrite the file with the + same contents. + + * The way of specifying the path to find dynamic libraries at runtime + has been simplified. The old default to pass -R/path/to/dir has been + replaced with the new default to pass -Wl,-rpath,/path/to/dir, + which is the more recent GCC uses. Those who need to build with an + old GCC can still use "CC_LD_DYNPATH=-R" + + * Prepare use of reachability index in topological walker that works + on a range (A..B). + + * A new tutorial targeting specifically aspiring git-core + developers has been added. + + * Auto-detect how to tell HP-UX aCC where to use dynamically linked + libraries from at runtime. + + * "git mergetool" and its tests now spawn fewer subprocesses. + + * Dev support update to help tracing out tests. + + * Support to build with MSVC has been updated. + + * "git fetch" that grabs from a group of remotes learned to run the + auto-gc only once at the very end. + + * A handful of Windows build patches have been upstreamed. + + * The code to read state files used by the sequencer machinery for + "git status" has been made more robust against a corrupt or stale + state files. + + * "git for-each-ref" with multiple patterns have been optimized. + + * The tree-walk API learned to pass an in-core repository + instance throughout more codepaths. + + * When one step in multi step cherry-pick or revert is reset or + committed, the command line prompt script failed to notice the + current status, which has been improved. + + * Many GIT_TEST_* environment variables control various aspects of + how our tests are run, but a few followed "non-empty is true, empty + or unset is false" while others followed the usual "there are a few + ways to spell true, like yes, on, etc., and also ways to spell + false, like no, off, etc." convention. + + * Adjust the dir-iterator API and apply it to the local clone + optimization codepath. + + * We have been trying out a few language features outside c89; the + coding guidelines document did not talk about them and instead had + a blanket ban against them. + + * A test helper has been introduced to optimize preparation of test + repositories with many simple commits, and a handful of test + scripts have been updated to use it. + + +Fixes since v2.22 +----------------- + + * A relative pathname given to "git init --template=<path> <repo>" + ought to be relative to the directory "git init" gets invoked in, + but it instead was made relative to the repository, which has been + corrected. + + * "git worktree add" used to fail when another worktree connected to + the same repository was corrupt, which has been corrected. + + * The ownership rule for the file descriptor to fast-import remote + backend was mixed up, leading to an unrelated file descriptor getting + closed, which has been fixed. + + * A "merge -c" instruction during "git rebase --rebase-merges" should + give the user a chance to edit the log message, even when there is + otherwise no need to create a new merge and replace the existing + one (i.e. fast-forward instead), but did not. Which has been + corrected. + + * Code cleanup and futureproof. + + * More parameter validation. + + * "git update-server-info" used to leave stale packfiles in its + output, which has been corrected. + + * The server side support for "git fetch" used to show incorrect + value for the HEAD symbolic ref when the namespace feature is in + use, which has been corrected. + + * "git am -i --resolved" segfaulted after trying to see a commit as + if it were a tree, which has been corrected. + + * "git bundle verify" needs to see if prerequisite objects exist in + the receiving repository, but the command did not check if we are + in a repository upfront, which has been corrected. + + * "git merge --squash" is designed to update the working tree and the + index without creating the commit, and this cannot be countermanded + by adding the "--commit" option; the command now refuses to work + when both options are given. + + * The data collected by fsmonitor was not properly written back to + the on-disk index file, breaking t7519 tests occasionally, which + has been corrected. + + * Update to Unicode 12.1 width table. + + * The command line to invoke a "git cat-file" command from inside + "git p4" was not properly quoted to protect a caret and running a + broken command on Windows, which has been corrected. + + * "git request-pull" learned to warn when the ref we ask them to pull + from in the local repository and in the published repository are + different. + + * When creating a partial clone, the object filtering criteria is + recorded for the origin of the clone, but this incorrectly used a + hardcoded name "origin" to name that remote; it has been corrected + to honor the "--origin <name>" option. + + * "git fetch" into a lazy clone forgot to fetch base objects that are + necessary to complete delta in a thin packfile, which has been + corrected. + + * The filter_data used in the list-objects-filter (which manages a + lazily sparse clone repository) did not use the dynamic array API + correctly---'nr' is supposed to point at one past the last element + of the array in use. This has been corrected. + + * The description about slashes in gitignore patterns (used to + indicate things like "anchored to this level only" and "only + matches directories") has been revamped. + + * The URL decoding code has been updated to avoid going past the end + of the string while parsing %-<hex>-<hex> sequence. + + * The list of for-each like macros used by clang-format has been + updated. + + * "git branch --list" learned to show branches that are checked out + in other worktrees connected to the same repository prefixed with + '+', similar to the way the currently checked out branch is shown + with '*' in front. + (merge 6e9381469e nb/branch-show-other-worktrees-head later to maint). + + * Code restructuring during 2.20 period broke fetching tags via + "import" based transports. + + * The commit-graph file is now part of the "files that the runtime + may keep open file descriptors on, all of which would need to be + closed when done with the object store", and the file descriptor to + an existing commit-graph file now is closed before "gc" finalizes a + new instance to replace it. + + * "git checkout -p" needs to selectively apply a patch in reverse, + which did not work well. + + * Code clean-up to avoid signed integer wraparounds during binary search. + + * "git interpret-trailers" always treated '#' as the comment + character, regardless of core.commentChar setting, which has been + corrected. + + * "git stash show 23" used to work, but no more after getting + rewritten in C; this regression has been corrected. + + * "git rebase --abort" used to leave refs/rewritten/ when concluding + "git rebase -r", which has been corrected. + + * An incorrect list of options was cached after command line + completion failed (e.g. trying to complete a command that requires + a repository outside one), which has been corrected. + + * The code to parse scaled numbers out of configuration files has + been made more robust and also easier to follow. + + * The codepath to compute delta islands used to spew progress output + without giving the callers any way to squelch it, which has been + fixed. + + * Protocol capabilities that go over wire should never be translated, + but it was incorrectly marked for translation, which has been + corrected. The output of protocol capabilities for debugging has + been tweaked a bit. + + * Use "Erase in Line" CSI sequence that is already used in the editor + support to clear cruft in the progress output. + + * "git submodule foreach" did not protect command line options passed + to the command to be run in each submodule correctly, when the + "--recursive" option was in use. + + * The configuration variable rebase.rescheduleFailedExec should be + effective only while running an interactive rebase and should not + affect anything when running a non-interactive one, which was not + the case. This has been corrected. + + * The "git clone" documentation refers to command line options in its + description in the short form; they have been replaced with long + forms to make them more recognisable. + + * Generation of pack bitmaps are now disabled when .keep files exist, + as these are mutually exclusive features. + (merge 7328482253 ew/repack-with-bitmaps-by-default later to maint). + + * "git rm" to resolve a conflicted path leaked an internal message + "needs merge" before actually removing the path, which was + confusing. This has been corrected. + + * "git stash --keep-index" did not work correctly on paths that have + been removed, which has been fixed. + (merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint). + + * Window 7 update ;-) + + * A codepath that reads from GPG for signed object verification read + past the end of allocated buffer, which has been fixed. + + * "git clean" silently skipped a path when it cannot lstat() it; now + it gives a warning. + + * "git push --atomic" that goes over the transport-helper (namely, + the smart http transport) failed to prevent refs to be pushed when + it can locally tell that one of the ref update will fail without + having to consult the other end, which has been corrected. + + * The internal diff machinery can be made to read out of bounds while + looking for --function-context line in a corner case, which has been + corrected. + (merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge fbec05c210 cc/test-oidmap later to maint). + (merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint). + (merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint). + (merge d61e6ce1dd sg/fsck-config-in-doc later to maint). diff --git a/Documentation/RelNotes/2.23.1.txt b/Documentation/RelNotes/2.23.1.txt new file mode 100644 index 0000000000..2083b492ce --- /dev/null +++ b/Documentation/RelNotes/2.23.1.txt @@ -0,0 +1,8 @@ +Git v2.23.1 Release Notes +========================= + +This release merges up the fixes that appear in v2.14.6, v2.15.4, +v2.17.3, v2.20.2 and in v2.21.1, addressing the security issues +CVE-2019-1348, CVE-2019-1349, CVE-2019-1350, CVE-2019-1351, +CVE-2019-1352, CVE-2019-1353, CVE-2019-1354, CVE-2019-1387, and +CVE-2019-19604; see the release notes for those versions for details. diff --git a/Documentation/RelNotes/2.23.2.txt b/Documentation/RelNotes/2.23.2.txt new file mode 100644 index 0000000000..b697cbe0e3 --- /dev/null +++ b/Documentation/RelNotes/2.23.2.txt @@ -0,0 +1,5 @@ +Git v2.23.2 Release Notes +========================= + +This release merges the security fix that appears in v2.17.4; see +the release notes for that version for details. |
