Junio C Hamano 4da45bef56 log: teach "terminator" vs "separator" mode to "--pretty=format"
This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.

The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields.  It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.

There are only two cases the code turns use_terminator on.  Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.

With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

  format-patch: generate MIME header as needed even when there is format.header
2008-03-15 00:09:33 -07:00
Junio C Hamano 6bf4f1b4c9 format-patch: generate MIME header as needed even when there is format.header
Earlier, the callchain from pretty_print_commit() down to pp_title_line()
had an unwarranted assumption that the presense of "after_subject"
parameter, means the caller has already output MIME headers for
attachments.  The parameter's primary purpose is to give extra header
lines the caller wants to place after pp_title_line() generates the
"Subject: " line.

This assumption does not hold when the user used the format.header
configuration variable to pass extra headers, and caused a message with
non-ASCII character to lack proper MIME headers (e.g.  8-bit CTE header).
The earlier logic also failed to suppress duplicated MIME headers when
"format-patch -s --attach" is asked for and the signer's name demanded
8-bit clean transport.

This patch fixes the logic by introducing a separate need_8bit_cte
parameter passed down the callchain.  This can have one of these values:

 -1 : we've already done MIME crap and we do not want to add extra header
      to say this is 8bit in pp_title_line();

  0 : we haven't done MIME and we have not seen anything that is 8bit yet;

  1 : we haven't done MIME and we have seen something that is 8bit;
      pp_title_line() must add MIME header.

It adds two tests by Jeff King who independently diagnosed this issue.

Junio C Hamano 3f061887c5 add -i: Fix running from a subdirectory
This fixes the pathspec interactive_add() passes to the underlying
git-add--interactive helper.  When the command was run from a
subdirectory, cmd_add() already has gone up to the toplevel of the work
tree, and the helper will be spawned from there.  The pathspec given on
the command line from the user needs to be adjusted for this.

This adds "validate_pathspec()" function in the callchain, but it does
not validate yet.  The function can be changed to barf if there are
unmatching pathspec given by the user, but that is not strictly
necessary.

Linus Torvalds 53b2c823f6 revision walker: mini clean-up
This removes the unnecessary indirection of "revs->prune_fn",
since that function is always the same one (or NULL), and there
is in fact not even an abstraction reason to make it a function
(i.e. its not called from some other file and doesn't allow us
to keep the function itself static or anything like that).

It then just replaces it with a bit that says "prune or not",
and if not pruning, every commit gets TREECHANGE.

That in turn means that

 - if (!revs->prune_fn || (flags & TREECHANGE))
 - if (revs->prune_fn && !(flags & TREECHANGE))

just become

 - if (flags & TREECHANGE)
 - if (!(flags & TREECHANGE))

respectively.

Together with adding the "single_parent()" helper function, the "complex"
conditional now becomes

	if (!(flags & TREECHANGE) && rev->dense && single_parent(commit))
		continue;

Also indirection of "revs->dense" checking is thrown away the
same way, because TREECHANGE bit is set appropriately now.

Pierre Habouzit 674d172730 Rework pretty_print_commit to use strbufs instead of custom buffers.
Also remove the "len" parameter, as:
  (1) it was used as a max boundary, and every caller used ~0u
  (2) we check for final NUL no matter what, so it doesn't help for speed.

  As a result most of the pp_* function takes 3 arguments less, and we need
a lot less local variables, this makes the code way more readable, and
easier to extend if needed.

  This patch also fixes some spacing and cosmetic issues.

  This patch also fixes (as a side effect) a memory leak intoruced in

Junio C Hamano 80583c0ef6 Lift 16kB limit of log message output
Traditionally we had 16kB limit when formatting log messages for
output, because it was easier to arrange for the caller to have
a reasonably big buffer and pass it down without ever worrying
about reallocating.

This changes the calling convention of pretty_print_commit() to
lift this limit.  Instead of the buffer and remaining length, it
now takes a pointer to the pointer that points at the allocated
buffer, and another pointer to the location that stores the
allocated length, and reallocates the buffer as necessary.

To support the user format, the error return of interpolate()
needed to be changed.  It used to return a bool telling "Ok the
result fits", or "Sorry, I had to truncate it".  Now it returns
0 on success, and returns the size of the buffer it wants in
order to fit the whole result.

Johannes Schindelin ed09aef06f support fetching into a shallow repository
A shallow commit is a commit which has parents, which in turn are
"grafted away", i.e. the commit appears as if it were a root.

Since these shallow commits should not be edited by the user, but
only by core git, they are recorded in the file $GIT_DIR/shallow.

A repository containing shallow commits is called shallow.

The advantage of a shallow repository is that even if the upstream
contains lots of history, your local (shallow) repository needs not
occupy much disk space.

The disadvantage is that you might miss a merge base when pulling
some remote branch.

Linus Torvalds 60ab26de99 [PATCH] Avoid wasting memory in git-rev-list
As pointed out on the list, git-rev-list can use a lot of memory.

One low-hanging fruit is to free the commit buffer for commits that we
parse. By default, parse_commit() will save away the buffer, since a lot
of cases do want it, and re-reading it continually would be unnecessary.
However, in many cases the buffer isn't actually necessary and saving it
just wastes memory.

We could just free the buffer ourselves, but especially in git-rev-list,
we actually end up using the helper functions that automatically add
parent commits to the commit lists, so we don't actually control the
commit parsing directly.

Instead, just make this behaviour of "parse_commit()" a global flag.
Maybe this is a bit tasteless, but it's very simple, and it makes a
noticable difference in memory usage.

Before the change:

	[torvalds@g5 linux]$ /usr/bin/time git-rev-list v2.6.12..HEAD > /dev/null
	0.26user 0.02system 0:00.28elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k
	0inputs+0outputs (0major+3714minor)pagefaults 0swaps

after the change:

	[torvalds@g5 linux]$ /usr/bin/time git-rev-list v2.6.12..HEAD > /dev/null
	0.26user 0.00system 0:00.27elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
	0inputs+0outputs (0major+2433minor)pagefaults 0swaps

note how the minor faults have decreased from 3714 pages to 2433 pages.
That's all due to the fewer anonymous pages allocated to hold the comment
buffers and their metadata.

Junio C Hamano f76412ed6d [PATCH] Add 'git show-branch'.
The 'git show-branches' command turns out to be reasonably useful,
but painfully slow.  So rewrite it in C, using ideas from merge-base
while enhancing it a bit more.

 - Unlike show-branches, it can take --heads (show me all my
   heads), --tags (show me all my tags), or --all (both).

 - It can take --more=<number> to show beyond the merge-base.

 - It shows the short name for each commit in the extended SHA1
   syntax.

 - It can find merge-base for more than two heads.

Examples:

    $ git show-branch --more=6 HEAD

    is almost the same as "git log --pretty=oneline --max-count=6".

    $ git show-branch --merge-base master mhf misc

    finds the merge base of the three given heads.

    $ git show-branch master mhf misc

    shows logs from the top of these three branch heads, up to their
    common ancestor commit is shown.

    $ git show-branch --all --more=10

    is poor-man's gitk, showing all the tags and heads, and
    going back 10 commits beyond the merge base of those refs.

Junio C Hamano d87449c553 Introduce --pretty=oneline format.
This introduces --pretty=oneline to git-rev-tree and
git-rev-list commands to show only the first line of the commit
message, without frills.
