Thomas Rast [Wed, 21 Dec 2011 15:54:14 +0000 (16:54 +0100)]
bash completion: use read -r everywhere

We use the 'read' command without -r, so that it treats '\' as an
escape character, in several places.  This breaks the loop reading
refnames from git-for-each-ref in __git_refs() if there are refnames
such as "foo'bar", in which case for-each-ref helpfully quotes them as

  $ git update-ref "refs/remotes/test/foo'bar" HEAD
  $ git for-each-ref --shell --format="ref=%(refname:short)" "refs/remotes"
  ref='test/foo'\''bar'

Interpolating the \' here will read "ref='test/foo'''bar'" instead, and
eval then chokes on the unbalanced quotes.

However, since none of the read loops _want_ to have backslashes
interpolated, it's much safer to use read -r everywhere.

12 years agogitweb: Fix fallback mode of to_utf8 subroutine
Jakub Narebski [Sun, 18 Dec 2011 22:00:58 +0000 (23:00 +0100)]
gitweb: Fix fallback mode of to_utf8 subroutine

e5d3de5 (gitweb: use Perl built-in utf8 function for UTF-8 decoding.,
2007-12-04) was meant to make gitweb faster by using Perl's internals
(see subsection "Messing with Perl's Internals" in Encode(3pm) manpage)

Simple benchmark confirms that (old = 00f429a, new = this version):

        old  new
  old    -- -65%
  new  189%   --

Unfortunately it made fallback mode of to_utf8 do not work...  except
for default value 'latin1' of $fallback_encoding ('latin1' is Perl
native encoding), which is why it was not noticed for such long time.

utf8::valid(STRING) is an internal function that tests whether STRING
is in a _consistent state_ regarding UTF-8.  It returns true is
well-formed UTF-8 and has the UTF-8 flag on _*or*_ if string is held
as bytes (both these states are 'consistent').  For gitweb the second
option was true, as output from git commands is opened without ':utf8'
layer.

What made it work at all for STRING in 'latin1' encoding is the fact
that utf8:decode(STRING) turns on UTF-8 flag only if source string is
valid UTF-8 and contains multi-byte UTF-8 characters... and that if
string doesn't have UTF-8 flag set it is treated as in native Perl
encoding, i.e.  'latin1' / 'iso-8859-1' (unless native encoding it is
EBCDIC ;-)).  It was ':utf8' layer that actually converted 'latin1'
(no UTF-8 flag == native == 'latin1) to 'utf8'.

Let's make use of the fact that utf8:decode(STRING) returns false if
STRING is invalid as UTF-8 to check whether to enable fallback mode.

Jeff King [Sat, 17 Dec 2011 10:45:39 +0000 (05:45 -0500)]
remote-curl: don't pass back fake refs

When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.

However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.

On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.

However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref).  But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.

Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.

Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).

This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

fetching and pushing was completely separate. Commit bde873c
refactored the verbosity handling out of the fetch side, and
then 8afd8dc converted push to use the refactored code.

However, the fetch and push sides numbered and passed along
their verbosity levels differently. For both, a verbosity
level of "-1" meant "quiet", and "0" meant "default output".
But from there they differed.

For fetch, a verbosity level of "1" indicated to the "fetch"
program that it should make the status table slightly more
verbose, showing up-to-date entries. A verbosity level of
"2" meant that we should pass a verbose flag to the
transport; in the case of fetch-pack, this displays protocol
debugging information.

As a result, the refactored code in bde873c checks for
"verbosity >= 2", and only then passes it on to the
transport. From the transport code's perspective, a
verbosity of 0 or 1 both meant "0".

Push, on the other hand, does not show its own status table;
that is always handled by the transport layer or below
(originally send-pack itself, but these days it is done by
the transport code). So a verbosity level of 1 meant that we
should pass the verbose flag to send-pack, so that it knows
we want a verbose status table. However, once 8afd8dc
switched it to the refactored fetch code, a verbosity level
of 1 was now being ignored.  Thus, you needed to
artificially bump the verbosity to 2 (via "-v -v") to have
any effect.

We can fix this by letting the transport code know about the
true verbosity level (i.e., let it distinguish level 0 or
1).

We then have to also make an adjustment to any transport
methods that assumed "verbose > 0" meant they could spew
lots of debugging information. Before, they could only get
"0" or "2", but now they will also receive "1". They need to
adjust their condition for turning on such spew from
"verbose > 0" to "verbose > 1".

12 years agogrep: disable threading in non-worktree case
Thomas Rast [Mon, 12 Dec 2011 21:16:08 +0000 (22:16 +0100)]
grep: disable threading in non-worktree case

Measurements by various people have shown that grepping in parallel is
not beneficial when the object store is involved.  For example, with a
simple regex:

  Threads     | --cached case            | worktree case
  ----------------------------------------------------------------
  8 (default) | 2.88u 0.21s 0:02.94real  | 0.19u 0.32s 0:00.16real
  4           | 2.89u 0.29s 0:02.99real  | 0.16u 0.34s 0:00.17real
  2           | 2.83u 0.36s 0:02.87real  | 0.18u 0.32s 0:00.26real
  NO_PTHREADS | 2.16u 0.08s 0:02.25real  | 0.12u 0.17s 0:00.31real

This happens because all the threads contend on read_sha1_mutex almost
all of the time.  A more complex regex allows the threads to do more
work in parallel, but as Jeff King found out, the "super boost" (much
higher clock when only one core is active) feature of recent CPUs
still causes the unthreaded case to win by a large margin.

So until the pack machinery allows unthreaded access, we disable
grep's threading in all but the worktree case.

use custom rename score during --follow

If you provide a custom rename score on the command line,
like:

  git log -M50 --follow foo.c

it is completely ignored, and there is no way to --follow
with a looser rename score. Instead, let's use the same
rename score that will be used for generating diffs. This is
convenient, and mirrors what we do with the break-score.

You can see an example of it being useful in git.git:

  530e741 Start preparing the API documents.
   create mode 100644 Documentation/technical/api-path-list.txt

You could have two separate rename scores, one for following
and one for diff. But almost nobody is going to want that,
and it would just be unnecessarily confusing. Besides which,
we re-use the diff results from try_to_follow_renames for
the actual diff output, which means having them as separate
scores is actively wrong. E.g., with the current code, you
get:

  $ git log --oneline --diff-filter=R --name-status \
            -M90 --follow git.spec.in
  27dedf0 GIT 0.99.9j aka 1.0rc3
  R084    git-core.spec.in        git.spec.in
  f85639c Rename the RPM from "git" to "git-core"
  R098    git.spec.in     git-core.spec.in

The first one should not be considered a rename by the -M
score we gave, but we print it anyway, since we blindly
re-use the diff information from the follow (which uses the
default score). So this could also be considered simply a
bug-fix, as with the current code "-M" is completely ignored
when using "--follow".
