008ed7df93 tag.c: use the correct algorithm for the '--contains' option
In b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-09-11) we port tag.c
to use the ref-filter APIs for filtering and printing refs.  In
ref-filter we have two implementations for filtering refs when the
'--contains' option is used.

Although they do the same thing, one is optimized for filtering
branches and the other for tags (borrowed from branch.c and tag.c
respectively) and the 'filter->with_commit_tag_algo' bit decides
which algorithm must be used.  We should unify these.

When we ported tag.c to use ref-filter APIs we missed out on setting
the 'filter->with_commit_tag_algo' bit.  As reported by Jerry
Snitselaar, this causes "git tag --contains" to work way slower than
expected, fix this by setting 'filter->with_commit_tag_algo' in
tag.c before calling 'filter_refs()'.

5242860f54 tag.c: implement '--merged' and '--no-merged' options
Use 'ref-filter' APIs to implement the '--merged' and '--no-merged'
options into 'tag.c'. The '--merged' option lets the user to only list
tags merged into the named commit. The '--no-merged' option lets the
user to only list tags not merged into the named commit.  If no object
is provided it assumes HEAD as the object.

Add documentation and tests for the same.

b7cc53e92c tag.c: use 'ref-filter' APIs
Make 'tag.c' use 'ref-filter' APIs for iterating through refs, sorting
and printing of refs. This removes most of the code used in 'tag.c'
replacing it with calls to the 'ref-filter' library.

Make 'tag.c' use the 'filter_refs()' function provided by 'ref-filter'
to filter out tags based on the options set.

For printing tags we use 'show_ref_array_item()' function provided by
'ref-filter'.

We improve the sorting option provided by 'tag.c' by using the sorting
options provided by 'ref-filter'. This causes the test 'invalid sort
parameter on command line' in t7004 to fail, as 'ref-filter' throws an
error for all sorting fields which are incorrect. The test is changed
to reflect the same.

Modify documentation for the same.

ac4cc866c8 tag.c: use 'ref-filter' data structures
Make 'tag.c' use 'ref-filter' data structures and make changes to
support the new data structures. This is a part of the process
of porting 'tag.c' to use 'ref-filter' APIs.

This is a temporary step before porting 'tag.c' to use 'ref-filter'
completely. As this is a temporary step, most of the code
introduced here will be removed when 'tag.c' is ported over to use
'ref-filter' APIs.

bef0e12bec ref-filter: add option to match literal pattern
Since 'ref-filter' only has an option to match path names add an
option for plain fnmatch pattern-matching.

This is to support the pattern matching options which are used in `git
tag -l` and `git branch -l` where we can match patterns like `git tag
-l foo*` which would match all tags which has a "foo*" pattern.

1bb38e5a6a ref-filter: add support for %(contents:lines=X)
In 'tag.c' we can print N lines from the annotation of the tag using
the '-n<num>' option. Copy code from 'tag.c' to 'ref-filter' and
modify it to support appending of N lines from the annotation of tags
to the given strbuf.

Implement %(contents:lines=X) where X lines of the given object are
obtained.

While we're at it, remove unused "contents:<suboption>" atoms from
the `valid_atom` array.

Add documentation and test for the same.

f932729cc7 memoize common git-path "constant" files
One of the most common uses of git_path() is to pass a
constant, like git_path("MERGE_MSG"). This has two
drawbacks:

  1. The return value is a static buffer, and the lifetime
     is dependent on other calls to git_path, etc.

  2. There's no compile-time checking of the pathname. This
     is OK for a one-off (after all, we have to spell it
     correctly at least once), but many of these constant
     strings appear throughout the code.

This patch introduces a series of functions to "memoize"
these strings, which are essentially globals for the
lifetime of the program. We compute the value once, take
ownership of the buffer, and return the cached value for
subsequent calls.  cache.h provides a helper macro for
defining these functions as one-liners, and defines a few
common ones for global use.

Using a macro is a little bit gross, but it does nicely
document the purpose of the functions. If we need to touch
them all later (e.g., because we learned how to change the
git_dir variable at runtime, and need to invalidate all of
the stored values), it will be much easier to have the
complete list.

Note that the shared-global functions have separate, manual
declarations. We could do something clever with the macros
(e.g., expand it to a declaration in some places, and a
declaration _and_ a definition in path.c). But there aren't
that many, and it's probably better to stay away from
too-magical macros.

Likewise, if we abandon the C preprocessor in favor of
generating these with a script, we could get much fancier.
E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz".
But the small amount of saved typing is probably not worth
the resulting confusion to readers who want to grep for the
function's definition.

0ea68e4296 get_repo_path: refactor path-allocation
The get_repo_path function calls mkpath() and then does some
non-trivial operations on it, like calling
is_git_directory() and read_gitfile(). These are actually
OK (they do not use more pathname static buffers
themselves), but it takes a fair bit of work to verify.

Let's use our own strbuf to store the path, and we can
simply reuse it for each iteration of the loop (we can even
avoid rewriting the beginning part, since we are trying a
series of suffixes).

To make the strbuf cleanup easier, we split out a thin
wrapper. As a bonus, this wrapper can factor out the
canonicalization that happens in all of the early-return
code paths.

b21a5d6605 remote.c: drop extraneous local variable from migrate_file
It's an anti-pattern to assign the result of git_path to a
variable, since other calls may reuse our buffer. In this
case, we feed the result to unlink_or_warn immediately
afterwards, so it's OK. However, it's nice to avoid
assignment entirely, which makes it more obvious that
there's no bug.

We can just pass the result directly to unlink_or_warn,
which is a known-simple function. As a bonus, the code flow
is a little more obvious, as we eliminate an extra
conditional (a reader does not have to wonder any more
"under which circumstances is 'path' set?").

e3cf230324 prefer mkpathdup to mkpath in assignments
As with the previous commit to git_path, assigning the
result of mkpath is suspicious, since it is not clear
whether we will still depend on the value after it may have
been overwritten by subsequent calls. This patch converts
low-hanging fruit to use mkpathdup instead of mkpath (with
the downside that we must remember to free the result).

fcd12db6af prefer git_pathdup to git_path in some possibly-dangerous cases
Because git_path uses a static buffer that is shared with
calls to git_path, mkpath, etc, it can be dangerous to
assign the result to a variable or pass it to a non-trivial
function. The value may change unexpectedly due to other
calls.

None of the cases changed here has a known bug, but they're
worth converting away from git_path because:

  1. It's easy to use git_pathdup in these cases.

  2. They use constructs (like assignment) that make it
     hard to tell whether they're safe or not.

The extra malloc overhead should be trivial, as an
allocation should be an order of magnitude cheaper than a
system call (which we are clearly about to make, since we
are constructing a filename). The real cost is that we must
remember to free the result.

ee2bd06b0f ref-filter: implement '--contains' option
'tag -l' and 'branch -l' have two different ways of finding
out if a certain ref contains a commit. Implement both these
methods in ref-filter and give the caller of ref-filter API
the option to pick which implementation to be used.

'branch -l' uses 'is_descendant_of()' from commit.c which is
left as the default implementation to be used.

'tag -l' uses a more specific algorithm since ffc4b80. This
implementation is used whenever the 'with_commit_tag_algo' bit
is set in 'struct ref_filter'.

7c32834813 for-each-ref: add '--merged' and '--no-merged' options
Add the '--merged' and '--no-merged' options provided by 'ref-filter'.
The '--merged' option lets the user to only list refs merged into the
named commit. The '--no-merged' option lets the user to only list refs
not merged into the named commit.

Add documentation and tests for the same.

35257aa012 ref-filter: implement '--merged' and '--no-merged' options
In 'branch -l' we have '--merged' option which only lists refs (branches)
merged into the named commit and '--no-merged' option which only lists
refs (branches) not merged into the named commit. Implement these two
options in ref-filter.{c,h} so that other commands can benefit from this.

14de7fba34 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.

c95b758587 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'.

b112b14d78 receive-pack: crash when checking with non-exist HEAD
If HEAD of a repository points to a conflict reference, such as:

* There exist a reference named 'refs/heads/jx/feature1', but HEAD
  points to 'refs/heads/jx', or

* There exist a reference named 'refs/heads/feature', but HEAD points
  to 'refs/heads/feature/bad'.

When we push to delete a reference for this repo, such as:

        git push /path/to/bad-head-repo.git :some/good/reference

The git-receive-pack process will crash.

This is because if HEAD points to a conflict reference, the function
`resolve_refdup("HEAD", ...)` does not return a valid reference name,
but a null buffer.  Later matching the delete reference against the null
buffer will cause git-receive-pack crash.

d830d395a1 builtin/send-pack.c: respect user.signingkey
When git-send-pack is exec'ed, as is done by git-remote-http, it
does not read the config, and configured value of user.signingkey is
ignored. Thus it was impossible to specify a signing key over HTTP,
other than the default key in the keyring having a User ID matching
the "Name <email>" format.

This patch at least partially fixes the problem by reading in the GPG
config from within send-pack. It does not address the related problem
of plumbing a value for this configuration option using
`git -c user.signingkey push ...`.

144c76fa39 update-ref and tag: add --create-reflog arg
Allow the creation of a ref (e.g. stash) with a reflog already in
place. For most refs (e.g. those under refs/heads), this happens
automatically, but for others, we need this option.

Currently, git does this by pre-creating the reflog, but alternate ref
backends might store reflogs somewhere other than .git/logs.  Code
that now directly manipulates .git/logs should instead use git
plumbing commands.

I also added --create-reflog to git tag, just for completeness.

In a moment, we will use this argument to make git stash work with
alternate ref backends.

abd0cd3a30 refs: new public ref function: safe_create_reflog
The safe_create_reflog function creates a reflog, if it does not
already exist.

The log_ref_setup function becomes private and gains a force_create
parameter to force the creation of a reflog even if log_all_ref_updates
is false or the refname is not one of the special refnames.

The new parameter also reduces the need to store, modify, and restore
the log_all_ref_updates global before reflog creation.

In a moment, we will use this to add reflog creation commands to
git-reflog.

a4c653dfcd refs.c: add err arguments to reflog functions
Add an err argument to log_ref_setup that can explain the reason
for a failure. This then eliminates the need to manage errno through
this function since we can just add strerror(errno) to the err string
when meaningful. No callers relied on errno from this function for
anything else than the error message.

Also add err arguments to private functions write_ref_to_lockfile,
log_ref_write_1, commit_ref_update. This again eliminates the need to
manage errno in these functions.

Some error messages are slightly reordered.

2d893dff4c rev-parse --parseopt: allow [*=?!] in argument hints
A line in the input to "rev-parse --parseopt" describes an option by
listing a short and/or long name, optional flags [*=?!], argument hint,
and then whitespace and help string.

We did not allow any of the [*=?!] characters in the argument hints.
The following input

    pair=key=value  equals sign in the hint

used to generate a help line like this:

    --pair=key <value>   equals sign in the hint

and used to expect "pair=key" as the argument name.

That is not very helpful as we generally do not want any of the [*=?!]
characters in the argument names.  But we do want to use at least the
equals sign in the argument hints.

Update the parser to make long argument names stop at the first [*=?!]
character.

Add test case with equals sign in the argument hint and update the test
to perform all the operations in test_expect_success matching the
t/README requirements and allowing commands like

    ./t1502-rev-parse-parseopt.sh --run=1-2

to stop at the test case 2 without any further modification of the test
state area.
