60d24dd255 Makefile: fold XDIFF_H and VCSSVN_H into LIB_H
Just like MISC_H (see previous commit), there is no reason to track
xdiff and vcs-svn headers separately from the rest of the headers.
The only purpose of these variables is to keep track of recompilation
dependencies.

As a pleasant side effect, folding these into LIB_H lets us stop
tracking GIT_OBJS and VCSSVN_TEST_OBJS separately from the list of all
OBJECTS.

76759c7dff git on Mac OS and precomposed unicode
Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA.  When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.

Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".

As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode.  Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode.  When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.

The unicode decomposition causes many problems:

- The names "git add" and other commands get from the end user may
  often be precomposed form (the decomposed form is not easily input
  from the keyboard), but when the commands read from the filesystem
  to see what it is going to update the index with already is on the
  filesystem, readdir() will give decomposed form, which is different.

- Similarly "git log", "git mv" and all other commands that need to
  compare pathnames found on the command line (often but not always
  precomposed form; a command line input resulting from globbing may
  be in decomposed) with pathnames found in the tree objects (should
  be precomposed form to be compatible with other systems and for
  consistency in general).

- The same for names stored in the index, which should be
  precomposed, that may need to be compared with the names read from
  readdir().

NFS mounted from Linux is fully transparent and does not suffer from
the above.

As Mac OS X treats precomposed and decomposed file names as equal,
we can

 - wrap readdir() on Mac OS X to return the precomposed form, and

 - normalize decomposed form given from the command line also to the
   precomposed form,

to ensure that all pathnames used in Git are always in the
precomposed form.  This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.

The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv().  The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.

The argv[] conversion allows to use the TAB filename completion done
by the shell on command line.  It tolerates other tools which use
readdir() to feed decomposed file names into git.

When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".

The user needs to activate this feature manually.  She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

5a29217dda git-remote-mediawiki: more efficient 'pull' in the best case
The only way to fetch new revisions from a wiki before this patch was to
query each page for new revisions. This is good when tracking a small set
of pages on a large wiki, but very inefficient when tracking many pages
on a wiki with little activity.

Implement a new strategy that queries the wiki for its last global
revision, queries each new revision, and filter out pages that are not
tracked.

5ef6ad1785 git-remote-mediawiki: scripts to install, delete and clear a MediaWiki
install_wiki.sh allows the user to install a MediaWiki instance in a
single shell command. Like "git instaweb", it configures and launches
lighttpd without requiring root priviledges. To simplify database
management, it uses SQLite, which doesn't require a running daemon, and
allows reseting the database by simply replacing a single file. This
allows install_wiki to also defines a function wiki_reset which clear all
content of the previously created wiki, which will be very useful to run
several indepenant tests on the same wiki.

Note those functionnalities are made to be used from the user command
line in the directory git/contrib/mw-to-git/t/

e32b79cb32 vcs-svn: allow 64-bit Prop-Content-Length
Currently the vcs-svn/ library only pays attention to the presence of
the Prop-Content-Length field and doesn't care about its value, but
some day we might care about the value.  Parse it as an off_t instead
of arbitrarily limiting to 32 bits for intuitiveness.

So now you can import from a dump with more than 2 GiB of properties
for a node.  In practice that isn't likely to happen often, and this
is mostly meant as a cleanup.

4a5de8dd79 vcs-svn: avoid self-assignment in dummy initialization of pre_off
Without this change, clang complains:

 vcs-svn/svndiff.c:298:3: warning: Assigned value is garbage or undefined

                 ^               ~~~~~~~

This code uses an old and common idiom for suppressing an
"uninitialized variable" warning, and clang is wrong to warn about it.
The idiom tells the compiler to leave the variable uninitialized,
which saves a few bytes of code size, and, more importantly, allows
valgrind to check at runtime that the variable is properly initialized
by the time it is used.

But MSVC and clang do not know that idiom, so let's avoid it in
vcs-svn/ code.

Initialize pre_off to -1, a recognizably meaningless value, to allow
future code changes that cause pre_off to be used before it is
initialized to be caught early.

5a45c0cafe gitweb: Cleanup git_print_log()
When we see a signed-off-by line (and its friends), we set $signoff
to true, but then we process the next line after we are done without
giving control to the rest of the loop.  And when the line we saw is
not a signed-off-by line, we reset $signoff to false before running
the remainder of the loop.

Hence, the check for $signoff that attempts to remove an extra empty
line between two signed-off-by line was not doing anything useful.

Rename $empty to a more explicit name $skip_blank_line to tell us to
skip a blank line when we see one, set it after we see and emit a
blank line (to avoid showing more than one empty lines in a raw) or
after we handle a signed-off-by line (to avoid empty lines after
such a line), to fix this bug, and get rid of the $signoff variable
that is not useful.

5742c82ba7 push: don't guess at qualifying remote refs on deletion
When we try to push a ref and the right-hand side of the
refspec does not find a match, we try to create it. If it is
not fully qualified, we try to guess where it would go in
the refs hierarchy based on the left-hand source side. If
the source side is not a ref, then we give up and give a
long explanatory message.

For deletions, however, this doesn't make any sense. We
would never want to create on the remote side, and if an
unqualified ref can't be matched, it is simply an error. The
current code handles this already because the left-hand side
is empty, and therefore does not give us a hint as to where
the right-hand side should go, and we properly error out.
Unfortunately, the error message is the long "we tried to
qualify this, but the source side didn't let us guess"
message, which is quite confusing.

Instead, we can just be more succinct and say "we can't
delete this because we couldn't find it". So before:

  $ git push origin :bogus
  error: unable to push to unqualified destination: bogus
  The destination refspec neither matches an existing ref on the remote nor
  begins with refs/, and we are unable to guess a prefix based on the source ref.
  error: failed to push some refs to '$URL'

and now:

  $ git push origin :bogus
  error: unable to delete 'bogus': remote ref does not exist
  error: failed to push some refs to '$URL'

It is tempting to also catch a fully-qualified ref like
"refs/heads/bogus" and generate the same error message.
However, that currently does not error out at all, and
instead gets sent to the remote side, which typically
generates a warning:

  $ git push origin:refs/heads/bogus
  remote: warning: Deleting a non-existent ref.
  To $URL
   - [deleted]         bogus

While it would be nice to catch this error early, a
client-side error would mean aborting the push entirely and
changing push's exit code. For example, right now you can
do:

  $ git push origin refs/heads/foo refs/heads/bar

and end up in a state where "foo" and "bar" are deleted,
whether both of them currently exist or not (and see an
error only if we actually failed to contact the server).
Generating an error would cause a regression for this use
case.

aa1dec9ef6 sha1_name.c: teach get_short_sha1() a commit-only option
When the caller knows that the parameter is meant to name a commit,
e.g. "56789a" in describe name "v1.2.3-4-g56789a", pass that as a
hint so that lower level can use it to disambiguate objects when
there is only one commit whose name begins with 56789a even if there
are objects of other types whose names share the same prefix.

37c00e5590 sha1_name.c: allow get_short_sha1() to take other flags
Instead of a separate "int quietly" argument, make it take "unsigned
flags" so that we can pass other options to it.

The bit assignment of this flag word is exposed in cache.h because
the mechanism will be exposed to callers of the higher layer in
later commits in this series.

c005e98612 get_sha1(): fix error status regression
In finish_object_disambiguation(), if the candidate hasn't been
checked, there are two cases:

 - It is the first and only object that match the prefix; or
 - It replaced another object that matched the prefix but that
   object did not satisfy ds->fn() callback.

And the former case we set ds->candidate_ok to true without doing
anything else, while for the latter we check the candidate, which
may set ds->candidate_ok to false.

At this point in the code, ds->candidate_ok can be false only if
this last-round check found that the candidate does not pass the
check, because the state after update_candidates() returns cannot
satisfy

    !ds->ambiguous && ds->candidate_exists && ds->candidate_checked

and !ds->canidate_ok at the same time.

Hence, when we execute this "return", we know we have seen more than
one object that match the prefix (and none of them satisfied ds->fn),
meaning that we should say "the short name is ambiguous", not "there
is no object that matches the prefix".

Noticed by Jeff King.

a78fafe74a sha1_name.c: restructure disambiguation of short names
We try to find zero, one or more matches from loose objects and
packed objects independently and then decide if the given short
object name is unique across them.

Instead, introduce a "struct disambiguate_state" that keeps track of
what we have found so far, that can be one of:

 - We have seen one object that _could_ be what we are looking for;
 - We have also checked that object for additional constraints (if any),
   and found that the object satisfies it;
 - We have also checked that object for additional constraints (if any),
   and found that the object does not satisfy it; or
 - We have seen more than one objects that satisfy the constraints.

and pass it to the enumeration functions for loose and packed
objects.  The disambiguation state can optionally take a callback
function that takes a candidate object name and reports if the
object satisifies additional criteria (e.g. when the caller knows
that the short name must refer to a commit, this mechanism can be
used to check the type of the given object).

Compared to the earlier attempt, this round avoids the optional
check if there is only one candidate that matches the short name in
the first place.
