The function replace_encoding_header is given the whole
commit buffer, including the commit message. When looking
for the encoding header, if none was found in the header, it
would locate any line in the commit message matching
"\nencoding " and remove it.

Instead, we now make sure to search only to the end of the

Linus Torvalds [Tue, 27 Mar 2007 16:50:20 +0000 (09:50 -0700)]
Fix "getaddrinfo()" buglet

At least in Linux glibc, "getaddrinfo()" has a very irritating feature (or
bug, who knows..).

Namely if you pass it in an empty string for the service name, it will
happily and quietly consider it identical to a NULL port pointer, and
return port number zero and no errors. Which obviously will not work.

Maybe that's what it's really expected to do, although the man-page for
getaddrinfo() certainly implies that it's a bug.

So when somebody passes me a "please pull" request pointing to something
like the following

git://git.kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb.git

(note the extraneous colon at the end of the host name), git would happily
try to connect to port 0, which would generally just cause the remote to
not even answer, and the "connect()" will take a long time to time out.

So to work around the glibc feature/bug, just notice this empty port case
automatically. Also, add the port information to the error information
when it fails to look up (maybe it's the host-name that fails, maybe it's
the port-name - we should print out both).

17 years agogitweb: Don't escape attributes in CGI.pm HTML methods
Jakub Narebski [Wed, 7 Mar 2007 01:21:25 +0000 (02:21 +0100)]
gitweb: Don't escape attributes in CGI.pm HTML methods

There is no need to escape HTML tag's attributes in CGI.pm
HTML methods (like CGI::a()), because CGI.pm does attribute
escaping automatically.

  $cgi->a({ ... -attribute => atribute_value }, tag_contents)

is translated to

  <a ... attribute="attribute_value">tag_contents</a>

The rules for escaping attribute values (which are string contents) are
different. For example you have to take care about escaping embedded '"'
and "'" characters; CGI::a() does that for us automatically.

CGI::a() does not HTML escape tag_contents; we would need to write

  <a href="URL">some <b>bold</b> text</a>

for example. So we use esc_html (or esc_path) to escape tag_contents
as needed.

17 years agoFix path-limited "rev-list --bisect" termination condition.
Junio C Hamano [Fri, 23 Mar 2007 20:34:49 +0000 (13:34 -0700)]
Fix path-limited "rev-list --bisect" termination condition.

In a path-limited bisection, when the $bad commit is not
changing the limited path, and the number of suspects is 1, the
code miscounted and returned $bad from find_bisection(), which
is not marked with TREECHANGE.  This is of course filtered by
the output routine, resulting in an empty output, in turn
causing git-bisect driver to say "$bad was both good and bad".

Illustration.  Suppose you have these four commits, and only C
changes path P.  You know D is bad and A is good.

A---B---C*--D

git-bisect driver runs this to find a bisection point:

$ git rev-list --bisect A..D -- P

which calls find_bisection() with B, C and D.  The set of
commits that is given to this function is the same set of
commits as rev-list without --bisect option and pathspec
returns.  Among them, only C is marked with TREECHANGE.  Let's
call the set of commits given to find_bisection() that are
marked with TREECHANGE (or all of them if no path limiter is in
effect) "the bisect set".  In the above example, the size of the
bisect set is 1 (contains only "C").

For each commit in its input, find_bisection() computes the
number of commits it can reach in the bisect set.  For a commit
in the bisect set, this number includes itself, so the number is
1 or more.  This number is called "depth", and computed by
count_distance() function.

When you have a bisect set of N commits, and a commit has depth
D, how good is your bisection if you returned that commit?  How
good this bisection is can be measured by how many commits are
effectively tested "together" by testing one commit.

Currently you have (N-1) untested commits (the tip of the bisect
set, although it is included in the bisect set, is already known
to be bad).  If the commit with depth D turns out to be bad,
then your next bisect set will have D commits and you will have
(D-1) untested commits left, which means you tested (N-1)-(D-1)
= (N-D) commits with this bisection.  If it turns out to be good, then
your next bisect set will have (N-D) commits, and you will have
(N-D-1) untested commits left, which means you tested
(N-1)-(N-D-1) = D commits with this bisection.

Therefore, the goodness of this bisection is is min(N-D, D), and
find_bisection() function tries to find a commit that maximizes
this, by initializing "closest" variable to 0 and whenever a
commit with the goodness that is larger than the current
"closest" is found, that commit and its goodness are remembered
by updating "closest" variable.  The "the commit with the best
goodness so far" is kept in "best" variable, and is initialized
to a commit that happens to be at the beginning of the list of
commits given to this function (which may or may not be in the
bisect set when path-limit is in use).

However, when N is 1, then the sole tree-changing commit has
depth of 1, and min(N-D, D) evaluates to 0.  This is not larger
than the initial value of "closest", and the "so far the best
one" commit is never replaced in the loop.

When path-limit is not in use, this is not a problem, as any
commit in the input set is tree-changing.  But when path-limit
is in use, and when the starting "bad" commit does not change
the specified path, it is not correct to return it.

17 years agoBe more careful about zlib return values
Linus Torvalds [Tue, 20 Mar 2007 18:38:34 +0000 (11:38 -0700)]
Be more careful about zlib return values

When creating a new object, we use "deflate(stream, Z_FINISH)" in a loop
until it no longer returns Z_OK, and then we do "deflateEnd()" to finish
up business.

That should all work, but the fact is, it's not how you're _supposed_ to
use the zlib return values properly:

 - deflate() should never return Z_OK in the first place, except if we
   need to increase the output buffer size (which we're not doing, and
   should never need to do, since we pre-allocated a buffer that is
   supposed to be able to hold the output in full). So the "while()" loop
   was incorrect: Z_OK doesn't actually mean "ok, continue", it means "ok,
   allocate more memory for me and continue"!

 - if we got an error return, we would consider it to be end-of-stream,
   but it could be some internal zlib error.  In short, we should check
   for Z_STREAM_END explicitly, since that's the only valid return value
   anyway for the Z_FINISH case.

 - we never checked deflateEnd() return codes at all.

Now, admittedly, none of these issues should ever happen, unless there is
some internal bug in zlib. So this patch should make zero difference, but
it seems to be the right thing to do.

We should probablybe anal and check the return value of "deflateInit()"
too!

17 years agodon't ever allow SHA1 collisions to exist by fetching a pack
Nicolas Pitre [Tue, 20 Mar 2007 19:32:35 +0000 (15:32 -0400)]
don't ever allow SHA1 collisions to exist by fetching a pack

Waaaaaaay back Git was considered to be secure as it never overwrote
an object it already had.  This was ensured by always unpacking the
packfile received over the network (both in fetch and receive-pack)
and our already existing logic to not create a loose object for an
object we already have.

Lately however we keep "large-ish" packfiles on both fetch and push
by running them through index-pack instead of unpack-objects.  This
would let an attacker perform a birthday attack.

How?  Assume the attacker knows a SHA-1 that has two different
data streams.  He knows the client is likely to have the "good"
one.  So he sends the "evil" variant to the other end as part of
a "large-ish" packfile.  The recipient keeps that packfile, and
indexes it.  Now since this is a birthday attack there is a SHA-1
collision; two objects exist in the repository with the same SHA-1.
They have *very* different data streams.  One of them is "evil".

Currently the poor recipient cannot tell the two objects apart,
short of by examining the timestamp of the packfiles.  But lets
say the recipient repacks before he realizes he's been attacked.
We may wind up packing the "evil" version of the object, and deleting
the "good" one.  This is made *even more likely* by Junio's recent
rearrange_packed_git patch (b867092f).

It is extremely unlikely for a SHA1 collisions to occur, but if it
ever happens with a remote (hence untrusted) object we simply must
not let the fetch succeed.

Normally received packs should not contain objects we already have.
But when they do we must ensure duplicated objects with the same SHA1
actually contain the same data.
