17b73dc699 strbuf_split*(): rename "delim" parameter to "terminator"
The word "delimiter" suggests that the argument separates the
substrings, whereas in fact (1) the delimiter characters are included
in the output, and (2) if the input string ends with the delimiter,
then the output does not include a final empty string.  So rename the
"delim" arguments of the strbuf_split() family of functions to
"terminator", which is more suggestive of how it is used.

895680f044 fmt-merge-msg: Add contents of merged tag in the merge message
When a contributor asks the integrator to merge her history, a signed tag
can be a good vehicle to communicate the authenticity of the request while
conveying other information such as the purpose of the topic.

E.g. a signed tag "for-linus" can be created, and the integrator can run:

   $ git pull git://example.com/work.git/ for-linus

This would allow the integrator to run "git verify-tag FETCH_HEAD" to
validate the signed tag.

Update fmt-merge-msg so that it pre-fills the merge message template with
the body (but not signature) of the tag object to help the integrator write
a better merge message, in the same spirit as the existing merge.log summary
lines.

The message that comes from GPG signature validation is also included in
the merge message template to help the integrator verify it, but they are
prefixed with "#" to make them comments.

2f1d9e2b93 strbuf: allow strbuf_split to work on non-strbufs
The strbuf_split function takes a strbuf as input, and
outputs a list of strbufs. However, there is no reason that
the input has to be a strbuf, and not an arbitrary buffer.

This patch adds strbuf_split_buf for a length-delimited
buffer, and strbuf_split_str for NUL-terminated strings.

28fc3a6857 strbuf_split: add a max parameter
Sometimes when splitting, you only want a limited number of
fields, and for the final field to contain "everything
else", even if it includes the delimiter.

This patch introduces strbuf_split_max, which provides a
"max number of fields" parameter; it behaves similarly to
perl's "split" with a 3rd field.

The existing 2-argument form of strbuf_split is retained for
compatibility and ease-of-use.

7141efab24 strbuf: clarify assertion in strbuf_setlen()
Commit a8f3e2219 introduced the strbuf_grow() call to strbuf_setlen() to
make ensure that there was at least one byte available to write the
mandatory trailing NUL, even for previously unallocated strbufs.

Then b315c5c0 added strbuf_slopbuf for the same reason, only globally for
all uses of strbufs.

Thus the strbuf_grow() call can be removed now.  This avoids readers of
strbuf.h from mistakenly thinking that strbuf_setlen() can be used to
extend a strbuf.

The following assert() needs to be changed to cope with the fact that
sb->alloc can now be zero, which is OK as long as len is also zero.  As
suggested by Junio, use the chance to convert it to a die() with a short
explanatory message.  The pattern of 'die("BUG: ...")' is already used in
strbuf.c.

This was the only assert() in strbuf.[ch], so assert.h doesn't have to be
included anymore either.

ebeb60900f strbuf: add strbuf_vaddf
In a variable-args function, the code for writing into a strbuf is
non-trivial. We ended up cutting and pasting it in several places
because there was no vprintf-style function for strbufs (which in turn
was held up by a lack of va_copy).

Now that we have a fallback va_copy, we can add strbuf_vaddf, the
strbuf equivalent of vsprintf. And we can clean up the cut and paste
mess.

81d2caefed strbuf_addbuf(): allow passing the same buf to dst and src
If sb and sb2 are the same (i.e. doubling the string), the underlying
strbuf_add() can make sb2->buf invalid by calling strbuf_grow(sb) at
the beginning; if realloc(3) done by strbuf_grow() needs to move the
string, strbuf_add() will read from an already freed buffer.

b11b7e13f4 Add generic 'strbuf_readlink()' helper function
It was already what 'git apply' did in read_old_data(), just export it
as a real function, and make it be more generic.

In particular, this handles the case of the lstat() st_size data not
matching the readlink() return value properly (which apparently happens
at least on NTFS under Linux).  But as a result of this you could also
use the new function without even knowing how big the link is going to
be, and it will allocate an appropriately sized buffer.

So we pass in the st_size of the link as just a hint, rather than a
fixed requirement.

The new callback function strbuf_expand_dict_cb() can be used together
with strbuf_expand() if there is only a small number of placeholders
for static replacement texts.  It expects its dictionary as an array of
placeholder+value pairs as context parameter, terminated by an entry
with the placeholder member set to NULL.

The new helper is intended to aid converting the remaining calls of
interpolate().  strbuf_expand() is smaller, more flexible and can be
used to go faster than interpolate(), so it should replace the latter.

c3a670de50 Avoid a useless prefix lookup in strbuf_expand()
Currently, the --pretty=format prefix is looked up in a
tight loop in strbuf_expand(), if prefix is found it is then
used as argument for format_commit_item() that does another
search by a switch statement to select the proper operation.

Because the switch statement is already able to discard
unknown matches we don't need the prefix lookup before
to call format_commit_item().

cde75e59e1 --pretty=format: on-demand format expansion
Some of the --pretty=format placeholders expansions are expensive to
calculate.  This is made worse by the current code's use of
interpolate(), which requires _all_ placeholders are to be prepared
up front.

One way to speed this up is to check which placeholders are present
in the format string and to prepare only the expansions that are
needed.  That still leaves the allocation overhead of interpolate().

Another way is to use a callback based approach together with the
strbuf library to keep allocations to a minimum and avoid string
copies.  That's what this patch does.  It introduces a new strbuf
function, strbuf_expand().

The function takes a format string, list of placeholder strings,
a user supplied function 'fn', and an opaque pointer 'context'
to tell 'fn' what thingy to operate on.

The function 'fn' is expected to accept a strbuf, a parsed
placeholder string and the 'context' pointer, and append the
interpolated value for the 'context' thingy, according to the
format specified by the placeholder.

Thanks to Pierre Habouzit for his suggestion to use strchrnul() and
the code surrounding its callsite.  And thanks to Junio for most of
this commit message. :)

b315c5c081 strbuf change: be sure ->buf is never ever NULL.
For that purpose, the ->buf is always initialized with a char * buf living
in the strbuf module. It is made a char * so that we can sloppily accept
things that perform: sb->buf[0] = '\0', and because you can't pass "" as an
initializer for ->buf without making gcc unhappy for very good reasons.

strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf
anymore.

as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying
->buf isn't an option anymore, if ->buf is going to escape from the scope,
and eventually be free'd.

API changes:
  * strbuf_setlen now always works, so just make strbuf_reset a convenience
    macro.
  * strbuf_detatch takes a size_t* optional argument (meaning it can be
    NULL) to copy the buffer's len, as it was needed for this refactor to
    make the code more readable, and working like the callers.

Add strbuf_swap:
  Exchange the values of its arguments.
  Use it in fast-import.c

Also fix spacing issues in strbuf.h

e6c019d0b0 Drop strbuf's 'eof' marker, and make read_line a first class citizen.
read_line is now strbuf_getline, and is a first class citizen, it returns 0
when reading a line worked, EOF else.

The ->eof marker was used non-locally by fast-import.c, mimic the same
behaviour using a static int in "read_next_command", that now returns -1 on
EOF, and avoids to call strbuf_getline when it's in EOF state.

Also no longer automagically strbuf_release the buffer, it's counter
intuitive and breaks fast-import in a very subtle way.

Note: being at EOF implies that command_buf.len == 0.

917c9a7133 New strbuf APIs: splice and attach.
* strbuf_splice replace a portion of the buffer with another.
* strbuf_attach replace a strbuf buffer with the given one, that should be
  malloc'ed. Then it enforces strbuf's invariants. If alloc > len, then this
  function has negligible cost, else it will perform a realloc, possibly
  with a cost.

Also some style issues are fixed now.

f1696ee398 Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces.
  * Add strbuf_insert to insert data at a given position.
  * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
    \0 so the overflow test for snprintf is the strict comparison. This is
    not critical as the growth mechanism chosen will always allocate _more_
    memory than asked, so the second test will not fail. It's some kind of
    miracle though.
  * Add size extension hints for strbuf_init and strbuf_read. If 0, default
    applies, else:
      + initial buffer has the given size for strbuf_init.
      + first growth checks it has at least this size rather than the
        default 8192.
