541c2a3a3d completion: add --autostash and --no-autostash to pull
Ideally we should only autocomplete if pull has --rebase since
they only work with it but could not figure out how to do that
and the error message of doing git pull --autostash points out
that you need --rebase so i guess it's good enough

The mailing address for the FSF has changed over the years.  Rather than
updating the address across all files, refer readers to gnu.org, as the
GNU GPL documentation now suggests for license notices.  The mailing
address is retained in the full license files (COPYING and LGPL-2.1).

The old address is still present in t/diff-lib/COPYING.  This is
intentional, as the file is used in tests and the contents are not
expected to change.

e9282f02b2 diff: --ignore-cr-at-eol
A new option --ignore-cr-at-eol tells the diff machinery to treat a
carriage-return at the end of a (complete) line as if it does not
exist.

Just like other "--ignore-*" options to ignore various kinds of
whitespace differences, this will help reviewing the real changes
you made without getting distracted by spurious CRLF<->LF conversion
made by your editor program.

f805a00a39 run-command: add hint when a hook is ignored
When an hook is present but the file is not set as executable then git will
ignore the hook.
For now this is silent which can be confusing.

This commit adds this warning to improve the situation:

  hint: The 'pre-commit' hook was ignored because it's not set as executable.
  hint: You can disable this warning with `git config advice.ignoredHook false`

To allow the old use-case of enabling/disabling hooks via the executable flag a
new setting is introduced: advice.ignoredHook.

5453b83bdf send-email: --batch-size to work around some SMTP server limit
Some email servers (e.g. smtp.163.com) limit the number emails to be
sent per session (connection) and this will lead to a faliure when
sending many messages.

Teach send-email to disconnect after sending a number of messages
(configurable via the --batch-size=<num> option), wait for a few
seconds (configurable via the --relogin-delay=<seconds> option) and
reconnect, to work around such a limit.

Also add two configuration variables to give these options the default.

Note:

  We will use this as a band-aid for now, but in the longer term, we
  should look at and react to the SMTP error code from the server;
  Xianqiang reports that 450 and 451 are returned by problematic
  servers.

0dab2468ee clone: add a --no-tags option to clone without tags
Add a --no-tags option to clone without fetching any tags.

Without this change there's no easy way to clone a repository without
also fetching its tags.

When supplying --single-branch the primary remote branch will be
cloned, but in addition tags will be followed & retrieved. Now
--no-tags can be added --single-branch to clone a repository without
tags, and which only tracks a single upstream branch.

This option works without --single-branch as well, and will do a
normal clone but not fetch any tags.

Many git commands pay some fixed overhead as a function of the number
of references. E.g. creating ~40k tags in linux.git will cause a
command like `git log -1 >/dev/null` to run in over a second instead
of in a matter of milliseconds, in addition numerous other things will
slow down, e.g. "git log <TAB>" with the bash completion will slowly
show ~40k references instead of 1.

The user might want to avoid all of that overhead to simply use a
repository like that to browse the "master" branch, or something like
a CI tool might want to keep that one branch up-to-date without caring
about any other references.

Without this change the only way of accomplishing this was either by
manually tweaking the config in a fresh repository:

    git init git &&
    cat >git/.git/config <<EOF &&
    [remote "origin"]
        url = git@github.com:git/git.git
        tagOpt = --no-tags
        fetch = +refs/heads/master:refs/remotes/origin/master
    [branch "master"]
        remote = origin
        merge = refs/heads/master
    EOF
    cd git &&
    git pull

Which requires hardcoding the "master" name, which may not be the main
--single-branch would have retrieved, or alternatively by setting
tagOpt=--no-tags right after cloning & deleting any existing tags:

    git clone --single-branch git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Which of course was also subtly buggy if --branch was pointed at a
tag, leaving the user in a detached head:

    git clone --single-branch --branch v2.12.0 git@github.com:git/git.git &&
    cd git &&
    git config remote.origin.tagOpt --no-tags &&
    git tag -l | xargs git tag -d

Now all this complexity becomes the much simpler:

    git clone --single-branch --no-tags git@github.com:git/git.git

Or in the case of cloning a single tag "branch":

    git clone --single-branch --branch v2.12.0 --no-tags git@github.com:git/git.git

60e71bbcea completion: optionally disable checkout DWIM
When we complete branch names for "git checkout", we also
complete remote branch names that could trigger the DWIM
behavior. Depending on your workflow and project, this can
be either convenient or annoying.

For instance, my clone of gitster.git contains 74 local
"jk/*" branches, but origin contains another 147. When I
want to checkout a local branch but can't quite remember the
name, tab completion shows me 251 entries. And worse, for a
topic that has been picked up for pu, the upstream branch
name is likely to be similar to mine, leading to a high
probability that I pick the wrong one and accidentally
create a new branch.

This patch adds a way for the user to tell the completion
code not to include DWIM suggestions for checkout. This can
already be done by typing:

  git checkout --no-guess jk/<TAB>

but that's rather cumbersome. The downside, of course, is
that you no longer get completion support when you _do_ want
to invoke the DWIM behavior. But depending on your workflow,
that may not be a big loss (for instance, in git.git I am
much more likely to want to detach, so I'd type "git
checkout origin/jk/<TAB>" anyway).

723c1d526f completion: expand "push --delete <remote> <ref>" for refs on that <remote>
Change the completion of "push --delete <remote> <ref>" to complete
refs on that <remote>, not all refs.

Before this cloning git.git and doing "git push --delete origin
p<TAB>" will complete nothing, since a fresh clone of git.git will
have no "pu" branch, whereas origin/p<TAB> will uselessly complete
origin/pu, but fully qualified references aren't accepted by
"--delete".

Now p<TAB> will complete as "pu". The completion of giving --delete
later, e.g. "git push origin --delete p<TAB>" remains unchanged, this
is a bug, but is a general existing limitation of the bash completion,
and not how git-push is documented, so I'm not fixing that case, but
adding a failing TODO test for it.

ac3f5a3468 ref-filter: add --no-contains option to tag/branch/for-each-ref
Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.

This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:

    (git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
        sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10

With this new --no-contains option the same can be achieved with:

    git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10

As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:

    git branch --contains v2.8.0 --no-contains v2.10.0

The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.

Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains.  The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.

The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.

In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

41d2716cdc completion: offer ctags symbol names for 'git log -S', '-G' and '-L:'
Just like in the case of search patterns for 'git grep', see 29eec71f2
(completion: match ctags symbol names in grep patterns, 2011-10-21)),
a common thing to look for using 'git log -S', '-G' and '-L:' is the
name of a symbol.

Teach the completion for 'git log' to offer ctags symbol names after
these options, both in stuck and in unstuck forms.

2f779f9176 completion: extract completing ctags symbol names into helper function
The previous commit doubled the number of __git_match_ctag()'s
positional parameters, and, to keep the position of existing
parameters for the sake of backwards compatibility, the prefix,
current word and suffix parameters ended up in different order than in
other functions accepting the same parameters.  Then there is a
condition checking the existence of the tag file before invoking this
function.

We could still live with this if there were only a single callsite,
but the next commit will add a few more, so it's worth providing a
cleaner interface.

Add the wrapper function __git_complete_symbol(), which encompasses
the condition for checking the presence of the tag file and filling
COMPREPLY, and accepts '--opt=val'-style options with default values
that keep callsites simpler.

7826a7865c completion: put matching ctags symbol names directly into COMPREPLY
The one-liner awk script in __git_match_ctag() listing ctags symbol
names for 'git grep <TAB>' is already smart enough to list only symbol
names matching the current word to be completed.

Extend this helper function to accept prefix and suffix parameters to
be prepended and appended, respectively, to each listed symbol name in
the awk script, so its output won't require any additional processing
or filtering in the completion script before being handed over to
Bash.  Use the faster __gitcomp_direct() helper instead of
__gitcomp_nl() to fill the fully processed matching symbol names into
Bash's COMPREPLY array.

Right after 'git grep <TAB>' in current git.git with 14k+ symbol names
in the tag file, best of five:

  Before:

    $ time __gitcomp_nl "$(__git_match_ctag "" tags)"

    real    0m0.178s
    user    0m0.176s
    sys     0m0.000s

  After:

227307a639 completion: speed up branch and tag completion
Modify __git_heads() and __git_tags() and the few callsites they have,
so we can let 'git for-each-ref' do all the hard work and these
functions' output won't need any further processing or filtering
before being handed over to Bash, resulting in faster branch and tag
completion.  These are some of the same tricks used in the previous
commits to speed up refs completion, namely:

  - Extend both functions to accept prefix, current word and suffix
    positional parameters, all optional and all empty by default to
    keep the parameterless behavior unaltered.

  - Specify appropriate globbing patterns to 'git for-each-ref' to
    list only branches or tags matching the given current word
    parameter.

  - Modify the 'git for-each-ref --format=<...>' to include the given
    prefix and suffix.

  - Adjust all callsites to specify the proper prefix, current word
    and suffix parameters, and to fill COMPREPLY using
    __gitcomp_direct().

745d655dc9 completion: fill COMPREPLY directly when completing fetch refspecs
The __git_complete_fetch_refspecs() has to iterate over __git_refs()'s
output anyway to turn the listed matching refs into refspecs, and it
knows about the prefix and suffix that has to be added to each
refspec.

Modify this function to add the prefix and suffix to each refspec
while iterating and feed the result, since it doesn't need further
processing, to the new __gitcomp_direct() helper added in the previous
commit, because it should be faster when there are a lot of refspecs
to list.

fef56eb006 completion: fill COMPREPLY directly when completing refs
__gitcomp_nl() iterates over all the possible completion words it gets
as argument

  - filtering matching words,
  - appending a trailing space to each matching word (in all but two
    cases),
  - prepending a prefix to each matching word (when completing words
    after e.g. '--option=<TAB>' or 'master..<TAB>'), and
  - adding each matching word to the COMPREPLY array.

This takes a while when a lot of refs are passed to __gitcomp_nl().

The previous changes in this series ensure that __git_refs() lists
only refs matching the current word to be completed, making a second
filtering in __gitcomp_nl() redundant.

Adding the necessary prefix and suffix could be done in __git_refs()
as well:

  - When refs come from 'git for-each-ref', then that prefix and
    suffix could be added much more efficiently using a 'git
    for-each-ref' format containing said prefix and suffix.  Care
    should be taken, though, because that prefix might contain
    'for-each-ref' format specifiers as part of the left hand side of
    a '..' range or '...' symmetric difference notation or
    fetch/push/etc. refspec, e.g. 'git log "evil-%(refname)..br<TAB>'.
    Doubling every '%' in the prefix will prevent 'git for-each-ref'
    from interpolating any of those contained specifiers.
  - When refs come from 'git ls-remote', then that prefix and suffix
    can be added in the shell loop that has to process 'git
    ls-remote's output anyway.
  - Finally, the prefix and suffix can be added to that handful of
    potentially matching symbolic and pseudo refs right away in the
    shell loop listing them.

And then all what is still left to do is to assign a bunch of
newline-separated words to a shell array, which can be done without a
shell loop iterating over each word, basically making all of
__gitcomp_nl() unnecessary for refs completion.

Add the helper function __gitcomp_direct() to fill the COMPREPLY array
with prefiltered and preprocessed words without any additional
processing, without a shell loop, with just one single compound
assignment.  Modify __git_refs() to accept prefix and suffix
parameters and add them to each and every listed ref as described
above.  Modify __git_complete_refs() to pass the prefix and suffix
parameters to __git_refs() and to feed __git_refs()'s output to
__gitcomp_direct() instead of __gitcomp_nl().

This speeds up refs completion when there are a lot of refs matching
the current word to be completed.  Listing all branches for completion
in a repo with 100k local branches, all packed, best of five:

400a7553c4 completion: let 'for-each-ref' sort remote branches for 'checkout' DWIMery
When listing unique remote branches for 'git checkout's tracking
DWIMery, __git_refs() runs the classic '... |sort |uniq -u' pattern to
filter out duplicate remote branches.

Let 'git for-each-ref' do the sorting, sparing the overhead of
fork()+exec()ing 'sort' and a stage in the pipeline where potentially
relatively large amount of data can be passed between two subsequent
pipeline stages.

This speeds up refs completion for 'git checkout' a bit when a lot of
remote branches match the current word to be completed.  Listing a
single local and 100k remote branches, all packed, best of five:
