+What's cooking in git.git (Oct 2009, #06; Fri, 30)
7
+--------------------------------------------------
8
+
9
+Here are the topics that have been cooking. Commits prefixed with '-' are
10
+only in 'pu' while commits prefixed with '+' are in 'next'. The ones
11
+marked with '.' do not appear in any of the integration branches, but I am
12
+still holding onto them.
13
+
14
+In 1.7.0, we plan to correct handful of warts in the interfaces everybody
15
+agrees that they were mistakes. The resulting system may not be strictly
16
+backward compatible. Currently planeed changes are:
17
+
18
+ * refuse push to update the checked out branch in a non-bare repo by
19
+ default
20
+
21
+ Make "git push" into a repository to update the branch that is checked
22
+ out fail by default. You can countermand this default by setting a
23
+ configuration variable in the receiving repository.
24
+
25
+ http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
26
+
27
+ * refuse push to delete the current branch by default
28
+
29
+ Make "git push $there :$killed" to delete the branch that is pointed at
30
+ by its HEAD fail by default. You can countermand this default by
31
+ setting a configuration variable in the receiving repository.
32
+
33
+ http://thread.gmane.org/gmane.comp.version-control.git/108862/focus=108936
34
+
35
+ * git-send-email won't make deep threads by default
36
+
37
+ Many people said that by default when sending more than 2 patches the
38
+ threading git-send-email makes by default is hard to read, and they
39
+ prefer the default be one cover letter and each patch as a direct
40
+ follow-up to the cover letter. You can countermand this by setting a
41
+ configuration variable.
42
+
43
+ http://article.gmane.org/gmane.comp.version-control.git/109790
44
+
45
+ * git-status won't be "git-commit --dry-run" anymore
46
+
47
+ http://thread.gmane.org/gmane.comp.version-control.git/125989/focus=125993
48
+
49
+ * "git-diff -w --exit-code" will exit success if only differences it
50
+ found are whitespace changes that are stripped away from the output.

200

201
+* jl/submodule-add-noname (2009-09-22) 1 commit.
202
+ - git submodule add: make the <path> parameter optional
203
+
204
+Dscho started an interesting discussion regarding the larger workflow in
205
+which the "submodule add" is used. I think the patch itself makes sense
206
+but at the same time it probably makes sense to also take the <path> and
207
+infer the <repository> as Dscho suggested, probably in "git submodule
208
+add", not in "git add" proper, at least initially.
209
+
210
+* sr/gfi-options (2009-09-06) 6 commits.
211
+ - fast-import: test the new option command

214
+ - fast-import: add feature command
215

218
+Seems to be moving again soon.

221
+ (merged to 'next' on 2009-10-11 at 1b99c56)
222
+ + send-email: confirm on empty mail subjects
223
+
224
+The existing tests cover the positive case (i.e. as long as the user says
225
+"yes" to the "do you really want to send this message that lacks subject",
226
+the message is sent) of this feature, but the feature itself needs its own
227
+test to verify the negative case (i.e. does it correctly stop if the user
228
+says "no"?)

427
+[For 1.7.0]
428
+
429
+* jc/1.7.0-no-commit-no-ff-2 (2009-10-22) 1 commit.
430
+ - git-merge: forbid fast-forward and up-to-date when --no-commit is given
431
+
432
+This makes "git merge --no-commit" fail when it results in fast-forward or
433
+up-to-date. I haven't described this at the beginning of this message
434
+yet, as it is not clear if this change is even necessary. Opinions?
435
+
436
+* jk/1.7.0-status (2009-09-05) 5 commits.
437
+ - docs: note that status configuration affects only long format
438
+ (merged to 'next' on 2009-10-11 at 65c8513)
439
+ + commit: support alternate status formats
440
+ + status: add --porcelain output format
441
+ + status: refactor format option parsing
442
+ + status: refactor short-mode printing to its own function
443
+ (this branch uses jc/1.7.0-status.)
444
+
445
+Gives the --short output format to post 1.7.0 "git commit --dry-run" that
446
+is similar to that of post 1.7.0 "git status".
447
+
448
+The tip one is not in 'next' as I have been hoping that somebody may want
449
+to change the code to make it unnecessary, but it does not seem to be
450
+happening, so probably it should also go to 'next'.
451
+
452
+* jc/1.7.0-status (2009-09-05) 4 commits.
453
+ (merged to 'next' on 2009-10-11 at 9558627)
454
+ + status: typo fix in usage
455
+ + git status: not "commit --dry-run" anymore
456
+ + git stat -s: short status output
457
+ + git stat: the beginning of "status that is not a dry-run of commit"
458
+ (this branch is used by jk/1.7.0-status.)
459
+
460
+With this, "git status" is no longer "git commit --dry-run".
461
+
462

463

467

468
+ + diff.c: fix typoes in comments
469
+ + Make test case number unique
470
+ + diff: Rename QUIET internal option to QUICK
471
+ + diff: change semantics of "ignore whitespace" options
472
+
473
+This changes exit code from "git diff --ignore-whitespace" and friends
474
+when there is no actual output. It is a backward incompatible change, but
475
+we could argue that it is a bugfix.
476
