1 Git v1.8.2 Release Notes
2 ========================
3
4 Backward compatibility notes
5 ----------------------------
6
7 In the upcoming major release (tentatively called 1.8.2), we will
8 change the behavior of the "git push" command.
9
10 When "git push [$there]" does not say what to push, we have used the
11 traditional "matching" semantics so far (all your branches were sent
12 to the remote as long as there already are branches of the same name
13 over there). We will use the "simple" semantics that pushes the
14 current branch to the branch with the same name, only when the current
15 branch is set to integrate with that remote branch. There is a user
16 preference configuration variable "push.default" to change this.

19 Updates since v1.8.1
20 --------------------
21
22 UI, Workflows & Features
23
24 * Initial ports to QNX and z/OS UNIX System Services have started.
25
26 * Output from the tests is coloured using "green is okay, yellow is
27 questionable, red is bad and blue is informative" scheme.
28
29 * In bare repositories, "git shortlog" and other commands now read
30 mailmap files from the tip of the history, to help running these
31 tools in server settings.
32
33 * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the
34 "--format=" option of "git log" and friends can be disabled when
35 the output is not sent to a terminal by prefixing them with
36 "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)".
37
38 * Scripts can ask Git that wildcard patterns in pathspecs they give do
39 not have any significance, i.e. take them as literal strings.
40
41 * "git fetch --mirror" and fetch that uses other forms of refspec
42 with wildcard used to attempt to update a symbolic ref that match
43 the wildcard on the receiving end, which made little sense (the
44 real ref that is pointed at by the symbolic ref would be updated
45 anyway). Symbolic refs no longer are affected by such a fetch.
46
47 * "git format-patch" now detects more cases in which a whole branch
48 is being exported, and uses the description for the branch, when
49 asked to write a cover letter for the series.
50
51 * "git push" now requires "-f" to update a tag, even if it is a
52 fast-forward, as tags are meant to be fixed points.
53
54 * "git submodule" started learning a new mode to integrate with the
55 tip of the remote branch (as opposed to integrating with the commit
56 recorded in the superproject's gitlink).
57
58
59 Foreign Interface
60
61 * "git fast-export" has been updated for its use in the context of
62 the remote helper interface.
63
64 * A new remote helper to interact with bzr has been added to contrib/.
65
66
67 Performance, Internal Implementation, etc.
68
69 * "git fsck" has been taught to be pickier about entries in tree
70 objects that should not be there, e.g. ".", ".git", and "..".
71
72 * Matching paths with common forms of pathspecs that contain wildcard
73 characters has been optimized further.
74
75 * The implementation of "imap-send" has been updated to reuse xml
76 quoting code from http-push codepath.
77
78
79 Also contains minor documentation updates and code clean-ups.

82 Fixes since v1.8.1
83 ------------------
84
85 Unless otherwise noted, all the fixes since v1.8.1 in the maintenance
86 track are contained in this release (see release notes to them for
87 details).
88
89 * An element on GIT_CEILING_DIRECTORIES list that does not name the
90 real path to a directory (i.e. a symbolic link) could have caused
91 the GIT_DIR discovery logic to escape the ceiling.
92 (merge 059b379 mh/ceiling later to maint).
93
94 * When attempting to read the XDG-style $HOME/.config/git/config and
95 finding that $HOME/.config/git is a file, we gave a wrong error
96 message, instead of treating the case as "a custom config file does
97 not exist there" and moving on.
98 (merge 8f2bbe4 jn/warn-on-inaccessible-loosen later to maint).
99
100 * The behaviour visible to the end users was confusing, when they
101 attempt to kill a process spawned in the editor that was in turn
102 launched by Git with SIGINT (or SIGQUIT), as Git would catch that
103 signal and die. We ignore these signals now.
104 (merge 1250857 pf/editor-ignore-sigint later to maint).
105
106 * After failing to create a temporary file using mkstemp(), failing
107 pathname was not reported correctly on some platforms.
108 (merge f7be59b jc/mkstemp-more-careful-error-reporting later to maint).
109
110 * The attribute mechanism didn't allow limiting attributes to be
111 applied to only a single directory itself with "path/" like the
112 exclude mechanism does.
113 (merge 94bc671 ja/directory-attrs later to maint).
114
115 * "git apply" misbehaved when fixing whitespace breakages by removing
116 excess trailing blank lines.
117 (merge 5de7166 jc/apply-trailing-blank-removal later to maint).
118
119 * The way "git svn" asked for password using SSH_ASKPASS and
120 GIT_ASKPASS was not in line with the rest of the system.
121 (merge e9263e4 ss/svn-prompt later to maint).
122
123 * The --graph code fell into infinite loop when asked to do what the
124 code did not expect.
125 (merge 656197a mk/maint-graph-infinity-loop later to maint).
126
127 * http transport was wrong to ask for the username when the
128 authentication is done by certificate identity.
129 (merge 75e9a40 rb/http-cert-cred-no-username-prompt later to maint).
130
131 * "git pack-refs" that ran in parallel to another process that
132 created new refs had a nasty race.
133 (merge b3f1280 jk/repack-ref-racefix later to maint).
134
135 * After "git add -N" and then writing a tree object out of the
136 index, the cache-tree data structure got corrupted.
137 (merge eec3e7e nd/invalidate-i-t-a-cache-tree later to maint).
138
139 * "git merge" started calling prepare-commit-msg hook like "git
140 commit" does some time ago, but forgot to pay attention to the exit
141 status of the hook.
142 (merge 3e4141d ap/merge-stop-at-prepare-commit-msg-failure later to maint).
143
144 * "gitweb", when sorting by age to show repositories with new
145 activities first, used to sort repositories with absolutely
146 nothing in it early, which was not very useful.
147 (merge 28dae18 md/gitweb-sort-by-age later to maint).
148
149 * "gitweb"'s code to sanitize control characters before passing it to
150 "highlight" filter lost known-to-be-safe control characters by
151 mistake.
152 (merge 0e901d2 os/gitweb-highlight-uncaptured later to maint).
153
154 * When a line to be wrapped has a solid run of non space characters
155 whose length exactly is the wrap width, "git shortlog -w" failed
156 to add a newline after such a line.
157 (merge e0db176 sp/shortlog-missing-lf later to maint).
158
159 * Some shells do not behave correctly when IFS is unset; work it
160 around by explicitly setting it to the default value.
161 (merge 393050c jc/maint-fbsd-sh-ifs-workaround later to maint).
162
163 * Some scripted programs written in Python did not get updated when
164 PYTHON_PATH changed.
165 (cherry-pick 96a4647fca54031974cd6ad1 later to maint).
166
167 * When autoconf is used, any build on a different commit always ran
168 "config.status --recheck" even when unnecessary.
169 (merge 1226504 jn/less-reconfigure later to maint).
170
171 * We have been carrying a translated and long-unmaintained copy of an
172 old version of the tutorial; removed.
173 (merge 0a85441 ta/remove-stale-translated-tut later to maint).
174
175 * t4014, t9502 and t0200 tests had various portability issues that
176 broke on OpenBSD.
177 (merge 27f6342 jc/maint-test-portability later to maint).
178
179 * t9020 and t3600 tests had various portability issues.
180 (merge 5a02966 jc/test-portability later to maint).
181
182 * t9200 runs "cvs init" on a directory that already exists, but a
183 platform can configure this fail for the current user (e.g. you
184 need to be in the cvsadmin group on NetBSD 6.0).
185 (merge 8666df0 jc/test-cvs-no-init-in-existing-dir later to maint).
186
187 * t9020 and t9810 had a few non-portable shell script construct.
188 (merge 2797914 tb/test-t9020-no-which later to maint).
189 (merge 6f4e505 tb/test-t9810-no-sed-i later to maint).
