1Git v1.7.10 Release Notes 2========================= 3 4Updates since v1.7.9 5-------------------- 6 7UI, Workflows & Features 8 9 * Improved handling of views, labels and branches in git-p4 (in contrib). 10 11 * "git-p4" (in contrib) suffered from unnecessary merge conflicts when 12 p4 expanded the embedded $RCS$-like keywords; it can be now told to 13 unexpand them. 14 15 * Some "git-svn" updates. 16 17 * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and 18 support incremental imports. 19 20 * The configuration mechanism learned an "include" facility; an 21 assignment to the include.path pseudo-variable causes the named 22 file to be included in-place when Git looks up configuration 23 variables. 24 25 * "git am" learned to pass "-b" option to underlying "git mailinfo", so 26 that bracketed string other than "PATCH" at the beginning can be kept. 27 28 * "git clone" learned "--single-branch" option to limit cloning to a 29 single branch (surprise!). 30 31 * "git clone" learned to detach the HEAD in the resulting repository 32 when the source repository's HEAD does not point to a branch. 33 34 * When showing a patch while ignoring whitespace changes, the context 35 lines are taken from the postimage, in order to make it easier to 36 view the output. 37 38 * "diff-highlight" filter (in contrib/) was updated to produce more 39 aesthetically pleasing output. 40 41 * "git merge" in an interactive session learned to spawn the editor 42 by default to let the user edit the auto-generated merge message, 43 to encourage people to explain their merges better. Legacy scripts 44 can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior. 45 Both "git merge" and "git pull" can be given --no-edit from the 46 command line to accept the auto-generated merge message. 47 48 * "git push" learned the "--prune" option, similar to "git fetch". 49 50 * "git tag --list" can be given "--points-at <object>" to limit its 51 output to those that point at the given object. 52 53 * "gitweb" allows intermediate entries in the directory hierarchy 54 that leads to a projects to be clicked, which in turn shows the 55 list of projects inside that directory. 56 57 * "gitweb" learned to read various pieces of information for the 58 repositories lazily, instead of reading everything that could be 59 needed (including the ones that are not necessary for a specific 60 task). 61 62Performance 63 64 * During "git upload-pack" in response to "git fetch", unnecessary calls 65 to parse_object() have been eliminated, to help performance in 66 repositories with excessive number of refs. 67 68Internal Implementation (please report possible regressions) 69 70 * Recursive call chains in "git index-pack" to deal with long delta 71 chains have been flattened, to reduce the stack footprint. 72 73 * Use of add_extra_ref() API is now gone, to make it possible to 74 cleanly restructure the overall refs API. 75 76 * The command line parser of "git pack-objects" now uses parse-options 77 API. 78 79 * The test suite supports the new "test_pause" helper function. 80 81 * Parallel to the test suite, there is a beginning of performance 82 benchmarking framework. 83 84 * t/Makefile is adjusted to prevent newer versions of GNU make from 85 running tests in seemingly random order. 86 87Also contains minor documentation updates and code clean-ups. 88 89 90Fixes since v1.7.9 91------------------ 92 93Unless otherwise noted, all the fixes since v1.7.9 in the maintenance 94releases are contained in this release (see release notes to them for 95details). 96 97 * The bulk check-in codepath streamed contents that needs 98 smudge/clean filters without running them, instead of punting and 99 delegating to the codepath to run filters after slurping everything 100 to core. 101 (merge 4f22b10 jk/maint-avoid-streaming-filtered-contents later to maint). 102 103 * When the filter driver exits before reading the content before the 104 main git process writes the contents to be filtered to the pipe to 105 it, the latter could be killed with SIGPIPE instead of ignoring 106 such an event as an error. 107 (merge 6424c2a jb/filter-ignore-sigpipe later to maint). 108 109 * When a remote helper exits before reading the blank line from the 110 main git process to signal the end of commands, the latter could be 111 killed with SIGPIPE. Instead we should ignore such event as a 112 non-error. 113 (merge c34fe63 sp/smart-http-failure-to-push later to maint). 114 115 * "git bundle create" produced a corrupt bundle file upon seeing 116 commits with excessively long subject line. 117 (merge 8a557bb tr/maint-bundle-long-subject later to maint). 118 119 * "gitweb" used to drop warnings in the log file when "heads" view is 120 accessed in a repository whose HEAD does not point at a valid 121 branch. 122 123--- 124exec >/var/tmp/1 125O=v1.7.9.2-301-g507fba2 126echo O=$(git describe) 127git log --first-parent --oneline ^maint $O.. 128echo 129git shortlog --no-merges ^maint $O..
