What's cooking in git.git (Apr 2013, #05; Mon, 15)
--------------------------------------------------

Here are the topics that have been cooking. Commits prefixed with
'-' are only in 'pu' (proposed updates) while commits prefixed with
'+' are in 'next'.

A handful of topics that have been stalled for quite a while have
been discarded; for those that are not superseded by something else,
interested parties can still resubmit a reroll, but without any
advances, we do not get any benefit from carrying them in my tree.

You can find the changes described here in the integration branches
of the repositories listed at

* po/help-guides (2013-04-03) 5 commits
(merged to 'next' on 2013-04-04 at 3d99b28)
+ doc: include --guide option description for "git help"
+ help: mention -a and -g option, and 'git help <concept>' usage.
+ builtin/help.c: add list_common_guides_help() function
+ builtin/help.c: add --guide option

* jk/diff-algo-finishing-touches (2013-04-05) 2 commits
(merged to 'next' on 2013-04-11 at af83b2b)
+ diff: allow unstuck arguments with --diff-algorithm
+ git-merge(1): document diff-algorithm option to merge-recursive

"git help" learned "-g" option to show the list of guides just like
list of commands are given with "-a".
"git diff --diff-algorithm algo" is also understood as "git diff
--diff-algorithm=algo".


* ap/combine-diff-coalesce-lost (2013-03-25) 1 commit
(merged to 'next' on 2013-03-29 at f6a05ca)

* jk/diff-graph-submodule-summary (2013-04-05) 1 commit

+ submodule: print graph output next to submodule log

Attempts to minimize "diff -c/--cc" output by coalescing the same
lines removed from the parents better, but with an O(n^2)
complexity.
Make "git diff --graph" work better with submodule log output.


* js/rerere-forget-protect-against-NUL (2013-04-04) 2 commits
(merged to 'next' on 2013-04-05 at 426d4e2)
+ rerere forget: do not segfault if not all stages are present
+ rerere forget: grok files containing NUL
* jk/http-error-messages (2013-04-06) 9 commits
(merged to 'next' on 2013-04-11 at 7a03981)
+ http: drop http_error function
+ remote-curl: die directly with http error messages
+ http: re-word http error message
+ http: simplify http_error helper function
+ remote-curl: consistently report repo url for http errors
+ remote-curl: always show friendlier 404 message
+ remote-curl: let servers override http 404 advice
+ remote-curl: show server content on http errors
+ http: add HTTP_KEEP_ERROR option

A few bugfixes to "git rerere" working on corner case merge
conflicts.
Improve error reporting from the http transfer clients.

(merged to 'next' on 2013-04-05 at 7f06945)
+ diffcore-pickaxe: unify code for log -S/-G
+ diffcore-pickaxe: fix leaks in "log -S<block>" and "log -G<pattern>"
+ diffcore-pickaxe: port optimization from has_changes() to diff_grep()
+ diffcore-pickaxe: respect --no-textconv

* jk/show-branch-strbuf (2013-04-06) 1 commit
(merged to 'next' on 2013-04-11 at 7a20aa5)
+ show-branch: use strbuf instead of static buffer

"git log -S/-G" started paying attention to textconv filter, but
there was no way to disable this. Make it honor --no-textconv
option.
"git show-branch" was not prepared to show a very long run of
ancestor operators e.g. foobar^2~2^2^2^2...^2~4 correctly.

* po/help-guides (2013-04-12) 1 commit

* lf/bundle-with-tip-wo-message (2013-04-07) 1 commit
(merged to 'next' on 2013-04-11 at bb9f869)
+ bundle: Accept prerequisites without commit messages

Finishing touches.
Will fast-track to 'master'.
"git bundle" did not like a bundle created using a commit without
any message as its one of the prerequistes.


* ap/strbuf-humanize (2013-04-10) 2 commits
- count-objects: add -H option to humanize sizes
- strbuf: create strbuf_humanise_bytes() to show byte sizes
* po/help-guides (2013-04-03) 5 commits

+ builtin/help.c: add list_common_guides_help() function
+ builtin/help.c: add --guide option
+ builtin/help.c: split "-a" processing into two

Teach "--human-readable" aka "-H" option to "git count-objects" to
show various large numbers in Ki/Mi/GiB scaled as necessary.
"git help" learned "-g" option to show the list of guides just like
list of commands are given with "-a".
* po/help-guides (2013-04-12) 1 commit
- help: mark common_guides[] as translatable

Will merge to 'next'.
Finishing touches.

It may not be a bad idea to discard mc/count-objects-kibibytes,
which can introduce regression to scripted users that expect the
output to say "N kilobytes". Opinions?

* rt/commentchar-fmt-merge-msg (2013-04-07) 2 commits
(merged to 'next' on 2013-04-11 at 6af638b)
+ fmt-merge-msg: use core.commentchar in tag signatures completely
+ fmt-merge-msg: respect core.commentchar in people credits

* as/clone-reference-with-gitfile (2013-04-09) 2 commits
- clone: Allow repo using gitfile as a reference
- clone: Fix error message for reference repository
The new core.commentchar configuration was not applied to a few
places.

"git clone" did not work if a repository pointed at by the
"--reference" option is a gitfile that points at another place.

Waiting for comments.
* tr/perl-keep-stderr-open (2013-04-04) 2 commits
(merged to 'next' on 2013-04-07 at 04f737a)
+ t9700: do not close STDERR
+ perl: redirect stderr to /dev/null instead of closing

Closing (not redirecting to /dev/null) the standard error stream is
not a very smart thing to do. Later open may return file
descriptor #2 for unrelated purpose, and error reporting code may
write into them.

* fc/transport-helper-error-reporting (2013-04-11) 3 commits

Rerolls kb/status-ignored-optim topic (reverted from 'next'). Not
merged to 'pu' as it heavily interferes with as/check-ignore topic.

Allow various subcommands of "git submodule" to be run not from the
top of the working tree of the superproject.
* mv/ssl-ftp-curl (2013-04-12) 1 commit
(merged to 'next' on 2013-04-15 at 7fdada6)
+ Support FTP-over-SSL/TLS for regular FTP

Waiting for comments.
Does anybody really use commit walkers over ftp???

Will merge to 'master'.

* kb/co-orphan-suggestion-short-sha1 (2013-04-08) 1 commit

- transport-helper: pass --signed-tags=warn-strip to fast-export
- fast-export: add --signed-tags=warn-strip mode

Allows remote-helpers to declare they can handle signed tags, and
issue a warning when using those that don't.

Comments?


* jn/config-ignore-inaccessible (2013-04-15) 1 commit
- config: allow inaccessible configuration under $HOME

When $HOME is misconfigured to point at an unreadable directory, we
used to complain and die. This loosens the check.

I do not think we agreed that this is a good idea, though.

Reword gitweb configuration instrutions.

Will merge to 'next'.

"git cherry-pick $blob $tree" is diagnosed as a nonsense.
Will merge to 'master'.

Will merge to 'next'.

- t5004: fix issue with empty archive test and bsdtar
* nd/checkout-keep-sparse (2013-04-15) 1 commit
- checkout: add --ignore-skip-worktree-bits in sparse checkout mode

Implementations of "tar" of BSD descend have found to have trouble
with reading an otherwise empty tar archive with pax headers and
causes an unnecessary test failure.
Make the initial "sparse" selection of the paths more sticky across
"git checkout".

Will merge to 'next'.

Teach "--human-readable" aka "-H" option to "git count-objects" to
show various large numbers in Ki/Mi/GiB scaled as necessary.

I've decided to let this topic supersede mc/count-objects-kibibytes.
Human users will get an even easier output with "-H" and by not

(merged to 'next' on 2013-04-05 at f4e50e8)
+ count-objects: output "KiB" instead of "kilobytes"

The command reports the total diskspace used to store loose objects
in kibibytes, but it was labelled as "kilobytes". The number now
is shown with "KiB", e.g. "6750 objects, 50928 KiB".

If you have scripts that decide when to run "git repack" by parsing
the output from "git count-objects", this release may break them.
Sorry about that. One of the scripts shipped by git-core itself
also had to be adjusted. You may want to consider updating such
scripts to always call "git gc --auto" to let it decide when to
repack for you.

Will merge to 'master'.

Allow smart-capable HTTP servers to be restricted via the
GIT_NAMESPACE mechanism when talking with commit-walker clients
(they already do so when talking with smart HTTP clients).

Closing (not redirecting to /dev/null) the standard error stream is
not a very smart thing to do. Later open may return file
descriptor #2 for unrelated purpose, and error reporting code may
write into them.

"git status --ignored" had many corner case bugs. Also the command
has been optimized by taking advantage of the fact that paths that
are already known to the index do not have to be checked against
the .gitignore mechanism most of the time.

This codepath is used not only by status but also in add and clean,
so a bug in it can result in lost data. Extra sets of eyeballs are
very much appreciated.

+ count-objects: output "KiB" instead of "kilobytes"

The command reports the total diskspace used to store loose objects
in kibibytes, but it was labelled as "kilobytes". The number now
is shown with "KiB", e.g. "6750 objects, 50928 KiB".

If you have scripts that decide when to run "git repack" by parsing
the output from "git count-objects", this release may break them.
Sorry about that. One of the scripts shipped by git-core itself
also had to be adjusted. You may want to consider updating such
