I am not sure if we want to use the owner bit (i.e. 4th place)
instead of the other bit (i.e. the last place) like this patch does,
though. The old code in 1.8.1.x would have produced either "r" (for
100644) or "wx" (for 100755); I think that the result of applying
this patch would give us "r" (for 100644) or "rx" (for 100755).
This should then work, I would think.

Subject: [PATCH v2] cvsserver: pick up the right mode bits
When determining the file mode from either ls-tree or diff-tree
output, we used to grab these octal mode string (typically 100644 or
100755) and then did
$git_perms .= "r" if ( $mode & 4 );
$git_perms .= "w" if ( $mode & 2 );
$git_perms .= "x" if ( $mode & 1 );
which was already wrong, as (100644 & 4) is very different from
oct("100644") & 4. An earlier refactoring 2c3af7e7 (cvsserver:
factor out git-log parsing logic, 2012-10-13) further changed it to
pick the third octal digit (10*0*644 or 10*0*755) from the left and
then do the above conversion, which does not make sense, either.
Let's use the third digit from the last of the octal mode string to
make sure we get the executable and read bits right.

I stopped interacting with CVS quite a long time ago, so I do not
have any way of verifying, but the fix may be just the matter of
something like this.
I am not sure if we want to use the owner bit (i.e. 4th place)
instead of the other bit (i.e. the last place) like this patch does,
though. The old code in 1.8.1.x would have produced either "r" (for
100644) or "wx" (for 100755); I think that the result of applying
this patch would give us "r" (for 100644) or "rx" (for 100755).

Matthew, I do not know if you are still using the git-cvsserver, but
it seems that the only substantial change to that subsystem between
the 1.8.1.x and 1.8.3.x is your update.
Especially 2c3af7e7 (cvsserver: factor out git-log parsing logic,
2012-10-13) looks interesting. It has a hunk like this:
-my $git_perms = "";
-$git_perms .= "r" if ( $mode & 4 );
-$git_perms .= "w" if ( $mode & 2 );
-$git_perms .= "x" if ( $mode & 1 );
-$git_perms = "rw" if ( $git_perms eq "" );
+my $dbMode = convertToDbMode($mode);
with the definition of convertToDbMode being:
+sub convertToDbMode
+{
+my $mode = shift;
+...
+$mode=~/^\d\d(\d)\d{3}$/;
+my $userBits=$1;
+
+my $dbMode = "";
+$dbMode .= "r" if ( $userBits & 4 );
+$dbMode .= "w" if ( $userBits & 2 );
+$dbMode .= "x" if ( $userBits & 1 );
+$dbMode = "rw" if ( $dbMode eq "" );
+
+return $dbMode;
The $mode in the caller comes from diff-tree output (the post-change
side of the mode string, like "100755").
Picking the third digit from the left (i.e. "10'0'755"), instead of
the tail digit (i.e. "10075'5'"), looks strange.
Side note: now I look at it, the original does not make much sense
for that matter. "100755" & 4 is different from oct("100755") & 4.

git-cvsserver strips exec bit
Hello, On git 1.8.1.x (Fedora 18) I was able to use the git-cvsserver to checkout code to package into a tarball. Script files that were in git with 755 masks were checked-out with the same mask. After upgrading the git repository machine to Fedora 19 (1.8.3.1) the behaviour has changed. When I checkout the same script files their mask is now 644. The mask has not changed in git. I understand I can use git-archive to perform the same functionality, but I'd like to report this issue here.
