Even if the user renames or moves + such a tag from its natural location in the "refs/tags/" hierarchy, + "git describe C" would still give T as the answer, but in such a + case "git show T^0" would no longer work as expected. There may be + nothing at "refs/tags/T" or even worse there may be a different tag + instead. + + Starting from this version, "git describe" will always use the + "long" version, as if the "--long" option were given, when giving + its output based on such a misplaced tag to work around the problem. + + * "git pull" issues a warning message until the pull.rebase + configuration variable is explicitly given, which some existing + users may find annoying---those who prefer not to rebase need to + set the variable to false to squelch the warning. + + +UI, Workflows & Features + + * A handful of options to configure SSL when talking to proxies have + been added. + + * Smudge/clean conversion filters are now given more information + (e.g. the object of the tree-ish in which the blob being converted + appears, in addition to its path, which has already been given). + + * When "git describe C" finds an annotated tag with tagname A to be + the best name to explain commit C, and the tag is stored in a + "wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the + command gave a warning message but used A (not B) to describe C. + If C is exactly at the tag, the describe output would be "A", but + "git rev-parse A^0" would not be equal as "git rev-parse C^0". The + behavior of the command has been changed to use the "long" form + i.e. A-0-gOBJECTNAME, which is correctly interpreted by rev-parse. + + * "git pull" learned to warn when no pull.rebase configuration + exists, and neither --[no-]rebase nor --ff-only is given (which + would result a merge). + + * "git p4" learned four new hooks and also "--no-verify" option to + bypass them (and the existing "p4-pre-submit" hook). + + * "git pull" shares many options with underlying "git fetch", but + some of them were not documented and some of those that would make + sense to pass down were not passed down. + + * "git rebase" learned the "--no-gpg-sign" option to countermand + commit.gpgSign the user may have. + + * The output from "git format-patch" uses RFC 2047 encoding for + non-ASCII letters on From: and Subject: headers, so that it can + directly be fed to e-mail programs. A new option has been added + to produce these headers in raw. + + * "git log" learned "--show-pulls" that helps pathspec limited + history views; a merge commit that takes the whole change from a + side branch, which is normally omitted from the output, is shown + in addition to the commits that introduce real changes. + + * The interactive input from various codepaths are consolidated and + any prompt possibly issued earlier are fflush()ed before we read. + + * Allow "git rebase" to reapply all local commits, even if the may be + already in the upstream, without checking first. + + * The 'pack.useSparse' configuration variable now defaults to 'true', + enabling an optimization that has been experimental since Git 2.21. + + +Performance, Internal Implementation, Development Support etc. + + * The advise API has been revamped to allow more systematic enumeration of + advice knobs in the future. + + * SHA-256 transition continues. + + * The code to interface with GnuPG has been refactored. + + * "git stash" has kept an escape hatch to use the scripted version + for a few releases, which got stale. It has been removed. + + * Enable tests that require GnuPG on Windows. + + * Minor test usability improvement. + + * Trace2 enhancement to allow logging of the environment variables. + + * Test clean-up continues. + + * Perf-test update. + + * A Windows-specific test element has been made more robust against + misuse from both user's environment and programmer's errors. + + +Fixes since v2.26 +----------------- + + * The real_path() convenience function can easily be misused; with a + bit of code refactoring in the callers' side, its use has been + eliminated. + (merge 49d3c4b481 am/real-path-fix later to maint). + + * Update "git p4" to work with Python 3. + (merge 6bb40ed20a yz/p4-py3 later to maint). + + * The mechanism to prevent "git commit" from making an empty commit + or amending during an interrupted cherry-pick was broken during the + rewrite of "git rebase" in C, which has been corrected. + (merge 430b75f720 pw/advise-rebase-skip later to maint). + + * Fix "git checkout --recurse-submodules" of a nested submodule + hierarchy. + (merge 846f34d351 pb/recurse-submodules-fix later to maint). + + * The "--fork-point" mode of "git rebase" regressed when the command + was rewritten in C back in 2.20 era, which has been corrected. + (merge f08132f889 at/rebase-fork-point-regression-fix later to maint). + + * The import-tars importer (in contrib/fast-import/) used to create + phony files at the top-level of the repository when the archive + contains global PAX headers, which made its own logic to detect and + omit the common leading directory ineffective, which has been + corrected. + (merge c839fcff65 js/import-tars-do-not-make-phony-files-from-pax-headers later to maint). + + * Simplify the commit ancestry connectedness check in a partial clone + repository in which "promised" objects are assumed to be obtainable + lazily on-demand from promisor remote repositories. + (merge 2b98478c6f jt/connectivity-check-optim-in-partial-clone later to maint). + + * The server-end of the v2 protocol to serve "git clone" and "git + fetch" was not prepared to see a delim packets at unexpected + places, which led to a crash. + (merge cacae4329f jk/harden-protocol-v2-delim-handling later to maint). + + * When fed a midx that records no objects, some codepaths tried to + loop from 0 through (num_objects-1), which, due to integer + arithmetic wrapping around, made it nonsense operation with out of + bounds array accesses. The code has been corrected to reject such + an midx file. + (merge 796d61cdc0 dr/midx-avoid-int-underflow later to maint). + + * Utitiles run via the run_command() API were not spawned correctly + on Cygwin, when the paths to them are given as a full path with + backslashes. + (merge 05ac8582bc ak/run-command-on-cygwin-fix later to maint). + + * "git pull --rebase" tried to run a rebase even after noticing that + the pull results in a fast-forward and no rebase is needed nor + sensible, for the past few years due to a mistake nobody noticed. + (merge fbae70ddc6 en/pull-do-not-rebase-after-fast-forwarding later to maint). + + * "git rebase" with the merge backend did not work well when the + rebase.abbreviateCommands configuration was set. + (merge de9f1d3ef4 ag/rebase-merge-allow-ff-under-abbrev-command later to maint). + + * The logic to auto-follow tags by "git clone --single-branch" was + not careful to avoid lazy-fetching unnecessary tags, which has been + corrected. + (merge 167a575e2d jk/use-quick-lookup-in-clone-for-tag-following later to maint). + + * "git rebase -i" did not leave the reflog entries correctly. + (merge 1f6965f994 en/sequencer-reflog-action later to maint). + + * The more aggressive updates to remote-tracking branches we had for + the past 7 years or so were not reflected in the documentation, + which has been corrected. + (merge a44088435c pb/pull-fetch-doc later to maint). + + * We've left the command line parsing of "git log :/a/b/" broken for + about a full year without anybody noticing, which has been + corrected. + (merge 0220461071 jc/missing-ref-store-fix later to maint). + + * Misc fixes for Windows. + (merge 3efc128cd5 js/mingw-fixes later to maint). + + * "git rebase" (again) learns to honor "--no-keep-empty", which lets + the user to discard commits that are empty from the beginning (as + opposed to the ones that become empty because of rebasing). The + interactive rebase also marks commits that are empty in the todo. + (merge 50ed76148a en/rebase-no-keep-empty later to maint). + + * Parsing the host part out of URL for the credential helper has been corrected. + (merge 4c5971e18a jk/credential-parsing-end-of-host-in-URL later to maint). + + * Other code cleanup, docfix, build fix, etc. + (merge 564956f358 jc/maintain-doc later to maint). + (merge 7422b2a0a1 sg/commit-slab-clarify-peek later to maint). + (merge 9c688735f6 rs/doc-passthru-fetch-options later to maint). + (merge 757c2ba3e2 en/oidset-uninclude-hashmap later to maint). + (merge 8312aa7d74 jc/config-tar later to maint). + (merge d00a5bdd50 ss/submodule-foreach-cb later to maint). + (merge 64d1022e14 ar/test-style-fixes later to maint). + (merge 4a465443a6 ds/doc-clone-filter later to maint). + (merge bb2dbe301b jk/t3419-drop-expensive-tests later to maint). + (merge d3507cc712 js/test-junit-finalization-fix later to maint). + (merge 2149b6748f bc/faq later to maint). + (merge 12dc0879f1 jk/test-cleanup later to maint). + (merge 344420bf0f pb/rebase-doc-typofix later to maint). + (merge 7cd54d37dc dl/wrapper-fix-indentation later to maint). + (merge 78725ebda9 jc/allow-strlen-substitution-in-shell-scripts later to maint). + (merge 2ecfcdecc6 jm/gitweb-fastcgi-utf8 later to maint). + (merge 0740d0a5d3 jk/oid-array-cleanups later to maint). + (merge a1aba0c95c js/t0007-typofix later to maint). + (merge 76ba7fa225 ma/config-doc-fix later to maint). |
