git-am: add am.threeWay config variable

Add the am.threeWay configuration variable to use the -3 or --3way
option of git am by default. When am.threeway is set and not desired
for a specific git am command, the --no-3way option can be used to
override it.

builtin-am: remove redirection to git-am.sh

At the beginning of the rewrite of git-am.sh to C, in order to not break
existing test scripts that depended on a functional git-am, a
redirection to git-am.sh was introduced that would activate if the
environment variable _GIT_USE_BUILTIN_AM was not defined.

Now that all of git-am.sh's functionality has been re-implemented in
builtin/am.c, remove this redirection, and retire git-am.sh into
contrib/examples/.

builtin-am: check for valid committer identPaul Tan Tue, 4 Aug 2015 13:52:05 +0000 (21:52 +0800)

builtin-am: check for valid committer ident

When commit_tree() is called, if the user does not have an explicit
committer ident configured, it will attempt to construct a default
committer ident based on the user's and system's info (e.g. gecos field,
hostname etc.) However, if a default committer ident is unable to be
constructed, commit_tree() will die(), but at this point of git-am's
execution, there will already be changes made to the index and work
tree.

This can be confusing to new users, and as such since d64e6b0 (Keep
Porcelainish from failing by broken ident after making changes.,
2006-02-18) git-am.sh will check to see if the committer ident has been
configured, or a default one can be constructed, before even starting to
apply patches.

builtin-am: implement legacy -b/--binary optionPaul Tan Tue, 4 Aug 2015 13:52:04 +0000 (21:52 +0800)

builtin-am: implement legacy -b/--binary option

The -b/--binary option was initially implemented in 087b674 (git-am:
--binary; document --resume and --binary., 2005-11-16). The option will
pass the --binary flag to git-apply to allow it to apply binary patches.

However, in 2b6eef9 (Make apply --binary a no-op., 2006-09-06), --binary
was been made a no-op in git-apply. Following that, since cb3a160
(git-am: ignore --binary option, 2008-08-09), the --binary option in
git-am is ignored as well.

In 6c15a1c (am: officially deprecate -b/--binary option, 2012-03-13),
the --binary option was tweaked to its present behavior: when set, the
message:

The -b/--binary option has been a no-op for long time, and it
will be removed. Please do not use it anymore.

will be printed.

builtin-am: implement -i/--interactive

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07),
git-am.sh supported the --interactive mode. After parsing the patch mail
and extracting the patch, commit message and authorship info, an
interactive session will begin that allows the user to choose between:

* applying the patch

* applying the patch and all subsequent patches (by disabling
interactive mode in subsequent patches)

* skipping the patch

* editing the commit message

Since f89ad67 (Add [v]iew patch in git-am interactive., 2005-10-25),
git-am.sh --interactive also supported viewing the patch to be applied.

When --resolved-ing in --interactive mode, we need to take care to
update the patch with the contents of the index, such that the correct
patch will be displayed when the patch is viewed in interactive mode.

builtin-am: support and auto-detect StGit patches

Since c574e68 (git-am foreign patch support: StGIT support, 2009-05-27),
git-am.sh supported converting StGit patches into RFC2822 mail patches
that can be parsed with git-mailinfo.

Implement this by introducing two functions in builtin/am.c:
stgit_patch_to_mail() and split_mail_conv().

stgit_patch_to_mail() is a callback function for split_mail_conv(), and
contains the logic for converting an StGit patch into an RFC2822 mail
patch.

split_mail_conv() implements the logic to go through each file in the
`paths` list, reading from stdin where specified, and calls the callback
function to write the converted patch to the corresponding output file
in the state directory. This interface should be generic enough to
support other foreign patch formats in the future.

Since 15ced75 (git-am foreign patch support: autodetect some patch

builtin-am: implement patch queue mechanismPaul Tan Tue, 4 Aug 2015 13:51:25 +0000 (21:51 +0800)

builtin-am: implement patch queue mechanism

git-am applies a series of patches. If the process terminates
abnormally, we want to be able to resume applying the series of patches.
This requires the session state to be saved in a persistent location.

Implement the mechanism of a "patch queue", represented by 2 integers --
the index of the current patch we are applying and the index of the last
patch, as well as its lifecycle through the following functions:

* am_setup(), which will set up the state directory
$GIT_DIR/rebase-apply. As such, even if the process exits abnormally,
the last-known state will still persist.

* am_load(), which is called if there is an am session in
progress, to load the last known state from the state directory so we
can resume applying patches.

* am_run(), which will do the actual patch application. After applying a
patch, it calls am_next() to increment the current patch index. The
logic for applying and committing a patch is not implemented yet.

* am_destroy(), which is finally called when we successfully applied all
the patches in the queue, to clean up by removing the state directory
and its contents.

builtin-am: implement skeletal builtin amPaul Tan Tue, 4 Aug 2015 13:51:24 +0000 (21:51 +0800)

builtin-am: implement skeletal builtin am

For the purpose of rewriting git-am.sh into a C builtin, implement a
skeletal builtin/am.c that redirects to $GIT_EXEC_PATH/git-am if the
environment variable _GIT_USE_BUILTIN_AM is not defined. Since in the
Makefile git-am.sh takes precedence over builtin/am.c,
$GIT_EXEC_PATH/git-am will contain the shell script git-am.sh, and thus
this allows us to fall back on the functional git-am.sh when running the
test suite for tests that depend on a working git-am implementation.

Since git-am.sh cannot handle any environment modifications by
setup_git_directory(), "am" is declared with no setup flags in git.c. On
the other hand, to re-implement git-am.sh in builtin/am.c, we need to
run all the git dir and work tree setup logic that git.c typically does
for us. As such, we work around this temporarily by copying the logic in
git.c's run_builtin(), which is roughly:

prefix = setup_git_directory();
trace_repo_setup(prefix);
setup_work_tree();

This redirection should be removed when all the features of git-am.sh
have been re-implemented in builtin/am.c.

for-each-ref: introduce filter_refs()Karthik Nayak Sat, 13 Jun 2015 19:37:28 +0000 (01:07 +0530)

for-each-ref: introduce filter_refs()

Introduce filter_refs() which will act as an API for filtering
a set of refs. Based on the type of refs the user has requested,
we iterate through those refs and apply filters as per the
given ref_filter structure and finally store the filtered refs
in the ref_array structure.

Currently this will wrap around ref_filter_handler(). Hence,
ref_filter_handler is made file scope static.

As users of this API will no longer send a ref_filter_cbdata
structure directly, we make the elements of ref_filter_cbdata
pointers. We can now use the information given by the users
to obtain our own ref_filter_cbdata structure. Changes are made to
support the change in ref_filter_cbdata structure.

Make 'for-each-ref' use this API.

ref-filter: move code from 'for-each-ref'

Move most of the code from 'for-each-ref' to 'ref-filter' to make
it publicly available to other commands, this is to unify the code
of 'tag -l', 'branch -l' and 'for-each-ref' so that they can share
their implementations with each other.

Add 'ref-filter' to the Makefile, this completes the movement of code
from 'for-each-ref' to 'ref-filter'.

GIT_PAGER_IN_USE environment variable that was meant as a local
communication between the original "Git" and subprocesses that was
spawned by it after we launched the pager, which caused many
"interesting" things to happen, e.g. "git diff | cat" still paints
its output in color by default.

strbuf: make strbuf_addftime more robustJeff King Tue, 30 Jun 2015 13:26:53 +0000 (09:26 -0400)

strbuf: make strbuf_addftime more robust

The return value of strftime is poorly designed; when it
returns 0, the caller cannot tell if the buffer was not
large enough, or if the output was actually 0 bytes. In the
original implementation of strbuf_addftime, we simply punted
and guessed that our 128-byte hint would be large enough.

We can do better, though, if we're willing to treat strftime
like less of a black box. We can munge the incoming format
to make sure that it never produces 0-length output, and
then "fix" the resulting output. That lets us reliably grow
the buffer based on strftime's return value.
