If an empty string is passed to link_alt_odb_entries(), our
loop finds no entries and we link nothing. But we still do
some preparatory work to normalize the object directory
path, even though we'll never look at the result. This
triggers in basically every git process, since we feed the
usually-empty ALTERNATE_DB_ENVIRONMENT to the function.
Let's detect early that there's nothing to do and return.
While we're at it, let's treat NULL the same as an empty
string as a favor to our callers. That saves
prepare_alt_odb() from having to cover this case.

The SubmittingPatches document is often cited by outside parties as an
example of good practices to follow, including logical, independent
commits; patch sign-offs; and sending patches to a mailing list.
Currently, people who want to cite a particular section tend to either
refer to it by name and let the interested party search through the
document to find it, or link to a given line number on GitHub and hope
the file doesn't change.
Instead, convert the document to AsciiDoc. Build it as part of the
technical documentation, since it is likely of interest to the same
group of people. Provide stable links to the sections which outside
parties are likely to want to link to. Make some minor structural
changes to organize it so that it can be formatted sanely.
Since the makefile needs a .txt extension in order to build with the
rest of the documentation, simply copy the file. Ignore the temporary
file so it doesn't get checked in accidentally, and remove it as part of
the clean process. Do this instead of renaming the file so that people
who have already linked to the documentation (who we're trying to help)
don't find their links broken. Avoid symlinking since Windows will not
like that.
This allows us to render the document as part of the website for the
benefit of others who wish to link to it as well as providing a more
nicely formatted display for our community and potential contributors.

If you have a pcre1 library which is compiled with JIT enabled then

This means that we enable JIT functionality when calling pcre_study

The test for '--abbrev' in t4201-shortlog.sh assumes that the commits
generated in the test can always be uniquely abbreviated to 5 hex digits
but this is not always the case. If you were unlucky and happened to run
the test at (say) Thu Jun 22 03:04:49 2017 +0000, you would find that
the first commit generated would collide with a tree object created
later in the same test.
This can be simulated in the version of t4201-shortlog.sh prior to this
commit by setting GIT_COMMITTER_DATE and GIT_AUTHOR_DATE to 1498100689
after sourcing test-lib.sh.
Change the test to test --abbrev=35 instead of --abbrev=5 to almost
completely avoid the possibility of a partial collision and add a call
to test_tick in the setup to make the test repeatable (the latter alone
is sufficient to make it robust enough).

ba1b9cac ("fsmonitor: delay updating state until after split index
is merged", 2017-10-27) resolved the problem of the fsmonitor data
being applied to the non-base index when reading; however, a similar
problem exists when writing the index. Specifically, writing of the
fsmonitor extension happens only after the work to split the index
has been applied -- as such, the information in the index is only
for the non-"base" index, and thus the extension information
contains only partial data.
When saving, compute the ewah bitmap before the index is split, and
store it in the fsmonitor_dirty field, mirroring the behavior that
occurred during reading. fsmonitor_dirty is kept from being leaked by
being freed when the extension data is written -- which always happens
precisely once, no matter the split index configuration.

In several functions, we iterate through a commit list by assigning
`result = result->next`. As a consequence, we lose the original pointer
and eventually leak the list.
Rewrite the loops so that we keep the original pointers, then call
`free_commit_list()`. Various alternatives were considered:
1) Use `UNLEAK(result)` before the loop. Simple change, but not very
pretty. These would definitely be new lows among our usages of UNLEAK.
2) Use `pop_commit()` when looping. Slightly less simple change, but it
feels slightly preferable to first display the list, then free it.
3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still
go through all the trouble of refactoring the loop, and because it's not
super-obvious that we're about to exit, let's just free the lists -- it
probably doesn't affect the runtime much.
In `handle_independent()` we can drop `result` while we're here and
reuse the `revs`-variable instead. That matches several other users of
`reduce_heads()`. The memory-leak that this hides will be addressed in
the next commit.

When we specify a list of namespaces to fetch from, by default the MW
API will not fetch from the default namespace, refered to as "(Main)"
in the documentation:
https://www.mediawiki.org/wiki/Manual:Namespace#Built-in_namespaces
I haven't found a way to address that "(Main)" namespace when getting
the namespace ids: indeed, when listing namespaces, there is no
"canonical" field for the main namespace, although there is a "*"
field that is set to "" (empty). So in theory, we could specify the
empty namespace to get the main namespace, but that would make
specifying namespaces harder for the user: we would need to teach
users about the "empty" default namespace. It would also make the code
more complicated: we'd need to parse quotes in the configuration.
So we simply override the query here and allow the user to specify
"(Main)" since that is the publicly documented name.

automatically.

There are times when scripts want to know not only the name of the
push branch on the remote, but also the name of the branch as known
by the remote repository.
An example of this is when a tool wants to push to the very same branch
from which it would pull automatically, i.e. the `<remote>` and the `<to>`
in `git push <remote> <from>:<to>` would be provided by
`%(upstream:remotename)` and `%(upstream:remoteref)`, respectively.
This patch offers the new suffix :remoteref for the `upstream` and `push`
atoms, allowing to show exactly that. Example:
$ cat .git/config
...
[remote "origin"]
url = https://where.do.we.come/from
fetch = refs/heads/*:refs/remote/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
[branch "develop/with/topics"]
remote = origin
merge = refs/heads/develop/with/topics
...
$ git for-each-ref \

Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules
file, 2017-08-03) rebase interactive fails if there are any submodules
with unstaged changes which have been configured with a value for
'submodule.<name>.ignore' in the repository's config.
This is due to how configured values of 'submodule.<name>.ignore' are
handled in addition to a change in how the submodule config is loaded.
When the diff machinery hits a submodule (gitlink as well as a
corresponding entry in the submodule subsystem) it will read the value
of 'submodule.<name>.ignore' stored in the repository's config and if
the config is present it will clear the 'IGNORE_SUBMODULES' (which is
the flag explicitly requested by rebase interactive),
'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff
flags and then set one of them based on the configured value.
Historically this wasn't a problem because the submodule subsystem
wasn't initialized because the .gitmodules file wasn't explicitly loaded
by the rebase interactive command. So when the diff machinery hit a
submodule it would skip over reading any configured values of
'submodule.<name>.ignore'.
In order to preserve the behavior of submodules being ignored by rebase
interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when
submodules are requested to be ignored when checking for unstaged
changes.

These function help read and write capabilities.
To make them more generic and make it easy to reuse them,
the following changes are made:
- we don't require capabilities to come in a fixed order,
- we allow duplicates,
- we check that the remote supports the capabilities we
advertise,
- we don't check if the remote declares any capability we
don't know about.
The reason behind the last change is that the protocol
should work using only the capabilities that both ends
support, and it should not stop working if one end starts
to advertise a new capability.
Despite those changes, we can still require a set of
capabilities, and die if one of them is not supported.
