This calculation occurs at the time $(PROGRAMS) is expanded,

Makefile: lazily compute header dependencies

Use the gcc -MMD -MP -MF options to generate dependency rules as
a byproduct when building .o files if the
COMPUTE_HEADER_DEPENDENCIES variable is defined.  That variable
is left undefined by default for now.

As each object file is built, write a makefile fragment
containing its dependencies in the deps/ subdirectory of its
containing directory.  The deps/ directories should be generated
if they are missing at the start of each build.  So let each
object file depend on $(missing_dep_dirs), which lists only the
directories of this kind that are missing to avoid needlessly
regenerating files when the directories' timestamps change.

gcc learned the -MMD -MP -MF options in version 3.0, so most gcc
users should have them by now.

The dependencies this option computes are more specific than the
rough estimates hard-coded in the Makefile, greatly speeding up

Makefile: disable default implicit rules

The git makefile never uses any default implicit rules.

Future patches may restrict the scope of the %.o: %.c pattern.

In Internet Explorer 8 (IE8) the 'blame_incremental' view, which uses
JavaScript to generate blame info using AJAX, sometimes hang at the
beginning (at 0%) of blaming, e.g. for larger files with long history
like git's own gitweb/gitweb.perl.

The error shown by JavaScript console is "Unspecified error" at char:2
of the following line in gitweb/gitweb.js:

  if (xhr.readyState === 3 && xhr.status !== 200) {

Debugging it using IE8 JScript debuger shown that the error occurs
when trying to access xhr.status (xhr is XMLHttpRequest object).
Watch for xhr object shows 'Unspecified error.' as "value" of
xhr.status, and trying to access xhr.status from console throws error.

This bug is some intermittent bug, depending on XMLHttpRequest timing,
as it doesn't occur in all cases.  It is probably caused by the fact
that handleResponse is called from timer (pollTimer), to work around
the fact that some browsers call onreadystatechange handler only once
for each state change, and not like required for 'blame_incremental'
as soon as new data is available from server.  It looks like xhr
object is not properly initialized; still it is a bug to throw an
error when accessing xhr.status (and not use 'null' or 'undefined' as
value).

Work around this bug in IE8 by using try-catch block when accessing
xhr.status.

commit 57bddb11 (Documentation/git-merge: reword references to
"remote" and "pull", 2010-01-07) fixed the manual to drop the
assumption that the other branch being merged is from a remote
repository.  Unfortunately, in a few places, to do so it
introduced the antecedentless phrase "their versions".  Worse, in
passages like the following, 'they' is playing two roles.

|
| * Look at the diffs on their own. 'git log --merge -p <path>'

Using HEAD and MERGE_HEAD nicely assigns terminology to "our" and
"their" sides.  It also provides the reader with practice using
names that git will recognize on the command line.

Documentation: simplify How Merge Works

The user most likely does not care about the exact order of
operations because he cannot see it happening anyway.  Instead,
try to explain what it means to merge two commits into a single
tree.

While at it:

 - Change the heading to TRUE MERGE.  The entire manual page is
   about how merges work.

 - Document MERGE_HEAD.  It is a useful feature, since it makes
   the parents of the intended merge commit easier to refer to.

 - Do not assume commits named on the 'git merge' command line come
   from another repository.  For simplicity, the discussion of
   conflicts still does assume that there is only one and it is a
   branch head.

 - Do not start list items with `code`.  Otherwise, a toolchain bug

Documentation: emphasize when git merge terminates early

A merge-based operation in git can fail in two ways: one that
stops before touching anything, or one that goes ahead and
results in conflicts.

As the 'git merge' manual explains:

| A merge is always between the current `HEAD` and one or more
| commits (usually, branch head or tag), and the index file must
| match the tree of `HEAD` commit (i.e. the contents of the last commit)
| when it starts out.

Unfortunately, the placement of this sentence makes it easy to
skip over, and its formulation leaves the important point, that
any other attempted merge will be gracefully aborted, unspoken.

So give this point its own section and expand upon it.

Probably this could be simplified somewhat: after all, a change
registered in the index is just a special kind of local
uncommited change, so the second added paragraph is only a
special case of the first.  It seemed more helpful to be explicit
here.

Ramsay Jones [Wed, 20 Jan 2010 19:25:51 +0000 (19:25 +0000)]
msvc: Fix an "unrecognized option" linker warning

Having recently added support for building git-imap-send on
Windows, we now link against OpenSSL libraries, and the linker
issues the following warning:

    warning LNK4044: unrecognized option '/lssl'; ignored

In order to suppress the warning, we change the msvc linker
script to translate an '-lssl' parameter to the ssleay32.lib
library.

Note that the linker script was already including ssleay32.lib
(along with libeay32.lib) as part of the translation of the
'-lcrypto' library parameter.  However, libeay32.dll does not
depend on ssleay32.dll and can be used stand-alone, so we remove
ssleay32.lib from the '-lcrypto' translation.

The dependence of ssleay32.dll on libeay32.dll is represented in
the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable.

Also, add the corresponding change to the buildsystem generator.

Linus Torvalds [Thu, 21 Jan 2010 19:37:38 +0000 (11:37 -0800)]
Remove diff machinery dependency from read-cache

Exal Sibeaz pointed out that some git files are way too big, and that
add_files_to_cache() brings in all the diff machinery to any git binary
that needs the basic git SHA1 object operations from read-cache.c. Which
is pretty much all of them.

It's doubly silly, since add_files_to_cache() is only used by builtin
programs (add, checkout and commit), so it's fairly easily fixed by just
moving the thing to builtin-add.c, and avoiding the dependency entirely.

I initially argued to Exal that it would probably be best to try to depend
on smart compilers and linkers, but after spending some time trying to
make -ffunction-sections work and giving up, I think Exal was right, and
the fix is to just do some trivial cleanups like this.

This trivial cleanup results in pretty stunning file size differences.
The diff machinery really is mostly used by just the builtin programs, and
you have things like these trivial before-and-after numbers:

  -rwxr-xr-x 1 torvalds torvalds 1727420 2010-01-21 10:53 git-hash-object
  -rwxrwxr-x 1 torvalds torvalds  940265 2010-01-21 11:16 git-hash-object

Now, I'm not saying that 940kB is good either, but that's mostly all the
debug information - you can see the real code with 'size':

   text    data     bss     dec     hex filename
 418675    3920  127408  550003   86473 git-hash-object (before)
 230650    2288  111728  344666   5425a git-hash-object (after)

ie we have a nice 24% size reduction from this trivial cleanup.

It's not just that one file either. I get:

[torvalds@nehalem git]$ du -s /home/torvalds/libexec/git-core
45640 /home/torvalds/libexec/git-core (before)
33508 /home/torvalds/libexec/git-core (after)

so we're talking 12MB of diskspace here.

(Of course, stripping all the binaries brings the 33MB down to 9MB, so the
whole debug information thing is still the bulk of it all, but that's a
separate issue entirely)

Now, I'm sure there are other things we should do, and changing our
compiler flags from -O2 to -Os would bring the text size down by an
additional almost 20%, but this thing Exal pointed out seems to be some
good low-hanging fruit.
