1Git v1.7.11 Release Notes 2========================= 3 4Updates since v1.7.10 5--------------------- 6 7UI, Workflows & Features 8 9 * A new mode for push, "simple", which is a cross between "current" 10 and "upstream", has been introduced. "git push" without any refspec 11 will push the current branch out to the same name at the remote 12 repository only when it is set to track the branch with the same 13 name over there. The plan is to make this mode the new default 14 value when push.default is not configured. 15 16 * A couple of commands learned the "--column" option to produce 17 columnar output. 18 19 * A third-party tool "git subtree" is distributed in contrib/ 20 21 * Error messages given when @{u} is used for a branch without its 22 upstream configured have been clatified. 23 24 * Even with "-q"uiet option, "checkout" used to report setting up 25 tracking. Also "branch" learned the "-q"uiet option to squelch 26 informational message. 27 28 * The smart-http backend used to always override GIT_COMMITTER_* 29 variables with REMOTE_USER and REMOTE_ADDR, but these variables are 30 now preserved when set. 31 32 * "include.path" mechanism of the configuration files learned to 33 understand "~/path" and "~user/path". 34 35 * "git am" learned the "--include" option, which is an opposite of 36 existing the "--exclude" option. 37 38 * When "git am -3" needs to fall back to an application to a 39 synthesized preimage followed by a 3-way merge, the paths that 40 needed such treatment are now reported to the end user, so that the 41 result in them can be eyeballed with extra care. 42 43 * The output from "diff/log --stat" used to always allocate 4 columns 44 to show the number of modified lines, but not anymore. 45 46 * "git difftool" learned the "--dir-diff" option to spawn external 47 diff tools that can compare two directory hierarchies at a time 48 after populating two temporary directories, instead of running an 49 instance of the external tool once per a file pair. 50 51 * The "fmt-merge-msg" command learns to list the primary contributors 52 involved in the side topic you are merging. 53 54 * The cases "git push" fails due to non-ff can be broken into three 55 categories; each case is given a separate advise message. 56 57 * "git rebase" learned to optionally keep commits that do not 58 introduce any change in the original history. 59 60 * "git push --recurse-submodules" learned to optionally look into the 61 histories of submodules bound to the superproject and push them 62 out. 63 64 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header, 65 based on the commit date. 66 67 * "gitweb" learned to highlight the patch it outputs even more. 68 69Foreign Interface 70 71 * "git svn" used to die with unwanted SIGPIPE when talking with HTTP 72 server that uses keep-alive. 73 74 * "git svn" learned to use platform specific authentication 75 providers, e.g. gnome-keyring, kwallet, etc. 76 77 * "git p4" has been moved out of contrib/ area and has seen more work 78 on importing labels as tags from (and exporting tags as labels to) 79 p4. 80 81Performance and Internal Implementation (please report possible regressions) 82 83 * An experimental "version 4" format of the index file has been 84 introduced to reduce on-disk footprint and I/O overhead. 85 86 * The code to compute hash values for lines used by the internal diff 87 engine was optimized on little-endian machines, using the same 88 trick the kernel folks came up with. 89 90 * "git apply" had some memory leaks plugged. 91 92 * "git repack" used to write out unreachable objects as loose objects 93 when repacking, even if such loose objects will immediately pruned 94 due to its age. 95 96 * Setting up a revision traversal with many starting points was 97 inefficient as these were placed in a date-order priority queue 98 one-by-one. Now they are collected in the queue unordered first, 99 and sorted immediately before getting used. 100 101 * "git rev-parse --show-prefix" used to emit nothing when run at the 102 top-level of the working tree, but now it gives a blank line. 103 104 * Minor memory leak during unpack_trees (hence "merge" and "checkout" 105 to check out another branch) has been plugged. 106 107 * More lower-level commands learned to use the streaming API to read 108 from the object store without keeping everything in core. 109 110 * Because "sh" on the user's PATH may be utterly broken on some 111 systems, run-command API now uses SHELL_PATH, not /bin/sh, when 112 spawning an external command (not applicable to Windows port). 113 114 * The API to iterate over refs/ hierarchy has been tweaked to allow 115 walking only a subset of it more efficiently. 116 117Also contains minor documentation updates and code clean-ups. 118 119 120Fixes since v1.7.10 121------------------- 122 123Unless otherwise noted, all the fixes since v1.7.10 in the maintenance 124releases are contained in this release (see release notes to them for 125details). 126 127 * "git diff --stat" used to fully count a binary file with modified 128 execution bits whose contents is unmodified, which was not quite 129 right. 130 131 * "log -z --pretty=tformat:..." did not terminate each record with 132 NUL. The fix is not entirely correct when the output also asks for 133 --patch and/or --stat, though. 134 (merge fafd382 jk/maint-tformat-with-z later to maint). 135 136 * "git push" over smart-http lost progress output a few releases ago. 137 (merge e304aeb jk/maint-push-progress later to maint). 138 139 * A contrib script "rerere-train" did not work out of the box unless 140 user futzed with her $PATH. 141 (merge 53876fc jc/rerere-train later to maint). 142 143 * "log --graph" was not very friendly with "--stat" option and its 144 output had line breaks at wrong places. 145 (merge bafa16e lp/diffstat-with-graph later to maint).
