| Git v2.41 Release Notes |
| ======================= |
| |
| UI, Workflows & Features |
| |
| * Allow information carried on the WWW-Authenticate header to be |
| passed to the credential helpers. |
| |
| * A new "fetch.hideRefs" option can be used to exclude specified refs |
| from "rev-list --objects --stdin --not --all" traversal for |
| checking object connectivity, most useful when there are many |
| unrelated histories in a single repository. |
| |
| * "git push" has been taught to allow deletion of refs with one-level |
| names to help repairing a repository who acquired such a ref by |
| mistake. In general, we don't encourage use of such a ref, and |
| creation or update to such a ref is rejected as before. |
| |
| * Allow "git bisect reset" to check out the original branch when the |
| branch is already checked out in a different worktree linked to the |
| same repository. |
| |
| * A few subcommands have been taught to stop users from working on a |
| branch that is being used in another worktree linked to the same |
| repository. |
| |
| * "git format-patch" learned to write a log-message only output file |
| for empty commits. |
| |
| * "git format-patch" honors the src/dst prefixes set to nonstandard |
| values with configuration variables like "diff.noprefix", causing |
| receiving end of the patch that expects the standard -p1 format to |
| break. "format-patch" has been taught to ignore end-user configuration |
| and always use the standard prefixes. |
| |
| This is a backward compatibility breaking change. |
| |
| * Lift the limitation that colored prompts can only be used with |
| PROMPT_COMMAND mode. |
| |
| * "git blame --contents=<file> <rev> -- <path>" used to be forbidden, |
| but now it finds the origins of lines starting at <file> contents |
| through the history that leads to <rev>. |
| |
| * "git pack-redundant" gave a warning when run, as the command has |
| outlived its usefulness long ago and is nominated for future |
| removal. Now we escalate to give an error. |
| |
| * "git clone" from an empty repository learned to propagate the |
| choice of the hash algorithm from the source repository to the |
| newly created repository over any one of the v0/v1/v2 protocol. |
| |
| * "git mergetool" and "git difftool" learns a new configuration |
| guiDefault to optionally favor configured guitool over non-gui-tool |
| automatically when $DISPLAY is set. |
| |
| * "git branch -d origin/master" would say "no such branch", but it is |
| likely a missed "-r" if refs/remotes/origin/master exists. The |
| command has been taught to give such a hint in its error message. |
| |
| * Clean-up of the code path that deals with merge strategy option |
| handling in "git rebase". |
| |
| * "git clone --local" stops copying from an original repository that |
| has symbolic links inside its $GIT_DIR; an error message when that |
| happens has been updated. |
| |
| * "git branch --format=..." and "git format-patch --format=..." |
| learns "--omit-empty" to hide refs that whose formatting result |
| becomes an empty string from the output. |
| |
| * The sendemail-validate validate hook learned to pass the total |
| number of input files and where in the sequence each invocation is |
| via environment variables. |
| |
| * When "gc" needs to retain unreachable objects, packing them into |
| cruft packs (instead of exploding them into loose object files) has |
| been offered as a more efficient option for some time. Now the use |
| of cruft packs has been made the default and no longer considered |
| an experimental feature. |
| |
| * The output given by "git blame" that attributes a line to contents |
| taken from the file specified by the "--contents" option shows it |
| differently from a line attributed to the working tree file. |
| |
| * "git send-email" learned to give the e-mail headers to the validate |
| hook by passing an extra argument from the command line. |
| |
| * The credential subsystem learns to help OAuth framework. |
| |
| * The titles of manual pages used to be chomped at an unreasonably |
| short limit, which has been removed. |
| |
| * Error messages given when working on an unborn branch that is |
| checked out in another worktree have been improved. |
| |
| * The documentation was misleading about the interaction between |
| GIT_DEFAULT_HASH and "git clone", which has been clarified to |
| stress that the variable is to be ignored by the command. |
| |
| * "git send-email" learned "--header-cmd=<cmd>" that can inject |
| arbitrary e-mail header lines to the outgoing messages. |
| |
| * "git fsck" learned to detect bit-flip breakages in the reachability |
| bitmap files. |
| |
| * The "--stdin" option of "git name-rev" has been replaced with |
| the "--annotate-stdin" option more than a year ago. We stop |
| advertising it in the "git name-rev -h" output. |
| |
| * "git push --all" gained an alias "git push --branches". |
| |
| * "git fetch" learned the "--porcelain" option that emits what it did |
| in a machine-parseable format. |
| |
| * "git --attr-source=<tree> cmd $args" is a new way to have any |
| command to read attributes not from the working tree but from the |
| given tree object. |
| |
| |
| Performance, Internal Implementation, Development Support etc. |
| |
| * Code clean-up to clarify directory traversal API. |
| |
| * Code clean-up to clarify the rule that "git-compat-util.h" must be |
| the first to be included. |
| |
| * More work towards -Wunused. |
| |
| * Instead of forcing each command to choose to honor GPG related |
| configuration variables, make the subsystem lazily initialize |
| itself. |
| |
| * Remove workaround for ancient versions of DocBook to make it work |
| correctly with groff, which has not been necessary since docbook |
| 1.76 from 2010. |
| |
| * Code clean-up to include and/or uninclude parse-options.h file as |
| needed. |
| |
| * The code path that reports what "git fetch" did to each ref has |
| been cleaned up. |
| |
| * Assorted config API updates. |
| |
| * A few configuration variables to tell the cURL library that |
| different types of ssl-cert and ssl-key are in use have been added. |
| |
| * Split key function and data structure definitions out of cache.h to |
| new header files and adjust the users. |
| |
| * "git fetch --all" does not have to download and handle the same |
| bundleURI over and over, which has been corrected. |
| |
| * "git sparse-checkout" command learns a debugging aid for the sparse |
| rule definitions. |
| |
| * "git write-tree" learns to work better with sparse-index. |
| |
| * The on-disk reverse index that allows mapping from the pack offset |
| to the object name for the object stored at the offset has been |
| enabled by default. |
| |
| * "git fsck" learned to validate the on-disk pack reverse index files. |
| |
| * strtok() and strtok_r() are banned in this codebase. |
| |
| * The detect-compilers script to help auto-tweaking the build system |
| had trouble working with compilers whose version number has extra |
| suffixes. The script has been taught that certain suffixes (like |
| "-win32" in "gcc 10-win32") can be safely stripped as they share |
| the same features and bugs with the version without the suffix. |
| |
| * ctype tests have been taught to test EOF, too. |
| |
| * The implementation of credential helpers used fgets() over fixed |
| size buffers to read protocol messages, causing the remainder of |
| the folded long line to trigger unexpected behaviour, which has |
| been corrected. |
| |
| * The implementation of the default "negotiator", used to find common |
| ancestor over the network for object tranfer, used to be recursive; |
| it was updated to be iterative to conserve stackspace usage. |
| |
| * Our custom callout formatter is no longer used in the documentation |
| formatting toolchain, as the upstream default ones give better |
| output these days. |
| |
| * The tracing mechanism learned to notice and report when |
| auto-discovered bare repositories are being used, as allowing so |
| without explicitly stating the user intends to do so (with setting |
| GIT_DIR for example) can be used with social engineering as an |
| attack vector. |
| |
| * "git diff-files" learned not to expand sparse-index unless needed. |
| |
| |
| Fixes since v2.40 |
| ----------------- |
| |
| * "git fsck" learned to check the index files in other worktrees, |
| just like "git gc" honors them as anchoring points. |
| (merge 8d3e7eac52 jk/fsck-indices-in-worktrees later to maint). |
| |
| * Fix a segfaulting loop. The function and its caller may need |
| further clean-up. |
| (merge c5773dc078 ew/commit-reach-clean-up-flags-fix later to maint). |
| |
| * "git restore" supports options like "--ours" that are only |
| meaningful during a conflicted merge, but these options are only |
| meaningful when updating the working tree files. These options are |
| marked to be incompatible when both "--staged" and "--worktree" are |
| in effect. |
| (merge ee8a88826a ak/restore-both-incompatible-with-conflicts later to maint). |
| |
| * Simplify UI to control progress meter given by "git bundle" command. |
| (merge 8b95521edb jk/bundle-progress later to maint). |
| |
| * "git bundle" learned that "-" is a common way to say that the input |
| comes from the standard input and/or the output goes to the |
| standard output. It used to work only for output and only from the |
| root level of the working tree. |
| (merge 0bbe10313e jk/bundle-use-dash-for-stdfiles later to maint). |
| |
| * Once we start running, we assumed that the list of alternate object |
| databases would never change. Hook into the machinery used to |
| update the list of packfiles during runtime to update this list as |
| well. |
| (merge e2d003dbed ds/reprepare-alternates-when-repreparing-packfiles later to maint). |
| |
| * The code to parse "git rebase -X<opt>" was not prepared to see an |
| unparsable option string, which has been corrected. |
| (merge 15a4cc912e ab/fix-strategy-opts-parsing later to maint). |
| |
| * "git add -p" while the index is unmerged sometimes failed to parse |
| the diff output it internally produces and died, which has been |
| corrected. |
| (merge 28d1122f9c jk/add-p-unmerged-fix later to maint). |
| |
| * Fix for a "ls-files --format="%(path)" that produced nonsense |
| output, which was a bug in 2.38. |
| (merge cfb62dd006 aj/ls-files-format-fix later to maint). |
| |
| * "git receive-pack" that responds to "git push" requests failed to |
| clean a stale lockfile when killed in the middle, which has been |
| corrected. |
| (merge c55c30669c ps/receive-pack-unlock-before-die later to maint). |
| |
| * "git rev-parse --quiet foo@{u}", or anything that asks @{u} to be |
| parsed with GET_OID_QUIETLY option, did not quietly fail, which has |
| been corrected. |
| (merge dfbfdc521d fc/oid-quietly-parse-upstream later to maint). |
| |
| * Transports that do not support protocol v2 did not correctly fall |
| back to protocol v0 under certain conditions, which has been |
| corrected. |
| (merge eaa0fd6584 jk/fix-proto-downgrade-to-v0 later to maint). |
| |
| * time(2) on glib 2.31+, especially on Linux, goes out of sync with |
| higher resolution timers used for gettimeofday(2) and by the |
| filesystem. Replace all calls to it with a git_time() wrapper and |
| (merge 370ddcbc89 pe/time-use-gettimeofday later to maint). |
| |
| * Code clean-up to use designated initializers in parse-options API. |
| (merge 353e6d4554 sg/parse-options-h-initializers later to maint). |
| |
| * A recent-ish change to allow unicode character classes to be used |
| with "grep -P" triggered a JIT bug in older pcre2 libraries. |
| The problematic change in Git built with these older libraries has |
| been disabled to work around the bug. |
| (merge 14b9a04479 mk/workaround-pcre-jit-ucp-bug later to maint). |
| |
| * The wildmatch library code unlearns exponential behaviour it |
| acquired some time ago since it was borrowed from rsync. |
| (merge 3dc0b7f0dc pw/wildmatch-fixes later to maint). |
| |
| * The index files can become corrupt under certain conditions when |
| the split-index feature is in use, especially together with |
| fsmonitor, which have been corrected. |
| (merge 061dd722dc js/split-index-fixes later to maint). |
| |
| * Document what the pathname-looking strings in "rev-list --object" |
| output are for and what they mean. |
| (merge 15364d2a3c jk/document-rev-list-object-name later to maint). |
| |
| * Fix unnecessary truncation of generation numbers used in-core. |
| (merge d3af1c193d ps/ahead-behind-truncation-fix later to maint). |
| |
| * Code clean-up around the use of the_repository. |
| (merge 4a93b899c1 ab/remove-implicit-use-of-the-repository later to maint). |
| |
| * Consistently spell "Message-ID" as such, not "Message-Id". |
| (merge ba4324c4e1 jc/spell-id-in-both-caps-in-message-id later to maint). |
| |
| * Correct use of an uninitialized structure member. |
| (merge dc12ee77ab jx/cap-object-info-uninitialized-fix later to maint). |
| |
| * Tests had a few places where we ignored PERL_PATH and blindly used |
| /usr/bin/perl, which have been corrected. |
| (merge c1917156a0 jk/use-perl-path-consistently later to maint). |
| |
| * Documentation mark-up fix. |
| (merge 78b6369e67 la/mfc-markup-fix later to maint). |
| |
| * Doc toolchain update to remove old workaround for AsciiDoc. |
| (merge 8806120de6 fc/remove-header-workarounds-for-asciidoc later to maint). |
| |
| * The userdiff regexp patterns for various filetypes that are built |
| into the system have been updated to avoid triggering regexp errors |
| from UTF-8 aware regex engines. |
| (merge be39144954 rs/userdiff-multibyte-regex later to maint). |
| |
| * The approxidate() API has been simplified by losing an extra |
| function that did the same thing as another one. |
| (merge 8a7f0b666f rs/remove-approxidate-relative later to maint). |
| |
| * Code clean-up to replace a hardcoded constant with a CPP macro. |
| (merge c870de6502 rs/get-tar-commit-id-use-defined-const later to maint). |
| |
| * Doc build simplification. |
| (merge 9a09ed3229 fc/doc-stop-using-manversion later to maint). |
| |
| * "git archive" run from a subdirectory mishandled attributes and |
| paths outside the current directory. |
| (merge 92b1dd1b9e rs/archive-from-subdirectory-fixes later to maint). |
| |
| * The code to parse capability list for v0 on-wire protocol fell into |
| an infinite loop when a capability appears multiple times, which |
| has been corrected. |
| |
| * Geometric repacking ("git repack --geometric=<n>") in a repository |
| that borrows from an alternate object database had various corner |
| case bugs, which have been corrected. |
| (merge d85cd18777 ps/fix-geom-repack-with-alternates later to maint). |
| |
| * The "%GT" placeholder for the "--format" option of "git log" and |
| friends caused BUG() to trigger on a commit signed with an unknown |
| key, which has been corrected. |
| (merge 7891e46585 jk/gpg-trust-level-fix later to maint). |
| |
| * The completion script used to use bare "read" without the "-r" |
| option to read the contents of various state files, which risked |
| getting confused with backslashes in them. This has been |
| corrected. |
| (merge 197152098a ek/completion-use-read-r-to-read-literally later to maint). |
| |
| * A small API fix to the ort merge strategy backend. |
| (merge 000c4ceca7 en/ort-finalize-after-0-merges-fix later to maint). |
| |
| * The commit object parser has been taught to be a bit more lenient |
| to parse timestamps on the author/committer line with a malformed |
| author/committer ident. |
| (merge 90ef0f14eb jk/parse-commit-with-malformed-ident later to maint). |
| |
| * Retitle a test script with an overly narrow name. |
| (merge 8bb19c14fb ob/t3501-retitle later to maint). |
| |
| * Doc update to clarify how text and eol attributes interact to |
| specify the end-of-line conversion. |
| (merge 6696077ace ah/doc-attributes-text later to maint). |
| |
| * Gitk updates from GfW project. |
| (merge 99e70f3077 js/gitk-fixes-from-gfw later to maint). |
| |
| * "git diff --dirstat" leaked memory, which has been plugged. |
| (merge 83973981eb jc/dirstat-plug-leaks later to maint). |
| |
| * "git merge-tree" reads the basic configuration, which can be used |
| by git forges to disable replace-refs feature. |
| (merge b6551feadf ds/merge-tree-use-config later to maint). |
| |
| * Other code cleanup, docfix, build fix, etc. |
| (merge f7111175df as/doc-markup-fix later to maint). |
