1Git 2.11 Release Notes 2====================== 3 4Updates since v2.10 5------------------- 6 7UI, Workflows & Features 8 9 * "git format-patch --cover-letter HEAD^" to format a single patch 10 with a separate cover letter now numbers the output as [PATCH 0/1] 11 and [PATCH 1/1] by default. 12 13 * An incoming "git push" that attempts to push too many bytes can now 14 be rejected by setting a new configuration variable at the receiving 15 end. 16 17 * "git nosuchcommand --help" said "No manual entry for gitnosuchcommand", 18 which was not intuitive, given that "git nosuchcommand" said "git: 19 'nosuchcommand' is not a git command". 20 21 * "git clone --resurse-submodules --reference $path $URL" is a way to 22 reduce network transfer cost by borrowing objects in an existing 23 $path repository when cloning the superproject from $URL; it 24 learned to also peek into $path for presense of corresponding 25 repositories of submodules and borrow objects from there when able. 26 27 * The "git diff --submodule={short,log}" mechanism has been enhanced 28 to allow "--submodule=diff" to show the patch between the submodule 29 commits bound to the superproject. 30 31 32Performance, Internal Implementation, Development Support etc. 33 34 * The delta-base-cache mechanism has been a key to the performance in 35 a repository with a tightly packed packfile, but it did not scale 36 well even with a larger value of core.deltaBaseCacheLimit. 37 38 * Enhance "git status --porcelain" output by collecting more data on 39 the state of the index and the working tree files, which may 40 further be used to teach git-prompt (in contrib/) to make fewer 41 calls to git. 42 43 * Extract a small helper out of the function that reads the authors 44 script file "git am" internally uses. 45 (merge a77598e jc/am-read-author-file later to maint). 46 47 * Lifts calls to exit(2) and die() higher in the callchain in 48 sequencer.c files so that more helper functions in it can be used 49 by callers that want to handle error conditions themselves. 50 51 52Also contains various documentation updates and code clean-ups. 53 54 55Fixes since v2.10 56----------------- 57 58Unless otherwise noted, all the fixes since v2.9 in the maintenance 59track are contained in this release (see the maintenance releases' 60notes for details). 61 62 * Clarify various ways to specify the "revision ranges" in the 63 documentation. 64 (merge a117be4 po/range-doc later to maint). 65 66 * "diff-highlight" script (in contrib/) learned to work better with 67 "git log -p --graph" output. 68 (merge 3dbfe2b bh/diff-highlight-graph later to maint). 69 70 * The test framework left the number of tests and success/failure 71 count in the t/test-results directory, keyed by the name of the 72 test script plus the process ID. The latter however turned out not 73 to serve any useful purpose. The process ID part of the filename 74 has been removed. 75 (merge 5c885c1 jk/test-lib-drop-pid-from-results later to maint). 76 77 * Having a submodule whose ".git" repository is somehow corrupt 78 caused a few commands that recurse into submodules loop forever. 79 (merge 10f5c52 jc/submodule-anchor-git-dir later to maint). 80 81 * "git symbolic-ref -d HEAD" happily removes the symbolic ref, but 82 the resulting repository becomes an invalid one. Teach the command 83 to forbid removal of HEAD. 84 (merge 12cfa79 jc/forbid-symbolic-ref-d-HEAD later to maint). 85 86 * A test spawned a short-lived background process, which sometimes 87 prevented the test directory from getting removed at the end of the 88 script on some platforms. 89 (merge 5babb5b js/t6026-clean-up later to maint). 90 91 * Update a few tests that used to use GIT_CURL_VERBOSE to use the 92 newer GIT_TRACE_CURL. 93 (merge 14e2411 ep/use-git-trace-curl-in-tests later to maint). 94 95 * "git pack-objects --include-tag" was taught that when we know that 96 we are sending an object C, we want a tag B that directly points at 97 C but also a tag A that points at the tag B. We used to miss the 98 intermediate tag B in some cases. 99 (merge b773dde jk/pack-tag-of-tag later to maint). 100 101 * Update Japanese translation for "git-gui". 102 (merge 02748bc sy/git-gui-i18n-ja later to maint). 103 104 * "git fetch http::/site/path" did not die correctly and segfaulted 105 instead. 106 (merge d63ed6e jk/fix-remote-curl-url-wo-proto later to maint). 107 108 * "git commit-tree" stopped reading commit.gpgsign configuration 109 variable that was meant for Porcelain "git commit" in Git 2.9; we 110 forgot to update "git gui" to look at the configuration to match 111 this change. 112 (merge f14a310 js/git-gui-commit-gpgsign later to maint). 113 114 * Other minor doc, test and build updates and code cleanups. 115 (merge 3e1952e jk/squelch-false-warning-from-gcc-o3 later to maint). 116 (merge ca2baa3 rs/compat-strdup later to maint). 117 (merge d233097 rs/hex2chr later to maint). 118 (merge c00bfc9 js/t9903-chaining later to maint). 119 (merge 5e4e5bb sb/xdiff-remove-unused-static-decl later to maint). 120 (merge 5cb5fe4 sb/transport-report-missing-submodule-on-stderr later to maint). 121 (merge a1c8044 ah/misc-message-fixes later to maint). 122 (merge ca9b37e sb/diff-cleanup later to maint).
