CVS server was running the hook before the update action was
actually done. This performs the update before the hook is called.
The original commit that introduced the current incorrect behavior
was 394d66d "git-cvsserver runs hooks/post-update". The error in
ordering of the hook call appears to have gone unnoticed, but since
git-cvsserver is supposed to emulate receive-pack, it stands to
reason that the hook should be run *after* the update. Since this
behavior is inconsistent with recieve-pack, users are either:
1) not using post-update hooks with git-cvsserver;
2) using post-update hooks that don't care whether they are
called before or after the actual update occurs;
3) using post-update hooks *only* with git-cvsserver, and
relying on the hook being called just before the update.
This patch would affect only users in case 3. These users are
depending on fairly obviously wrong behavior, and moreover they can
simply change their current post-update into post-recieve hooks,
and their systems will work correctly again.

# the co request to update it. Without using expand-modules, the client

|
|
# working directories under the current directory, which could be
|
|
# unnecessarily slow, or it could be ignorant of the fact that aliasmodule

# stands for 1dir, and neglect to send information for 1dir, which would

=head1 NAME

GITCVS::log
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module provides very crude logging with a similar interface to
|
|
Log::Log4perl
|
|
|
|
=head1 METHODS
|
|
|
|
=cut
|
|
|
|
=head2 new
|
|
|
|
Creates a new log object, optionally you can specify a filename here to
|
|
indicate the file to log to. If no log file is specified, you can specify one
|
|
later with method setfile, or indicate you no longer want logging with method
|
|
nofile.
|
|
|
|
Until one of these methods is called, all log calls will buffer messages ready
|
|
to write out.
|
|
|

sub new
|
|
{
|
|
my $class = shift;

my $self = {};
|
|
|
|
bless $self, $class;
|
|
|
|
if ( defined ( $filename ) )
|
|
{
|
|
open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!");
|
|
}
|
|
|
|
return $self;
|
|
}
|
|
|
|
=head2 setfile
|
|
|
|
This methods takes a filename, and attempts to open that file as the log file.
|
|
If successful, all buffered data is written out to the file, and any further
|
|
logging is written directly to the file.
|
|
|
|
=cut
|
|
sub setfile
|
|
{
|

my $self = shift;

|
|
{
|
|
print {$self->{fh}} $line;
|
|
}
|
|
}
|
|
|
|
=head2 nofile
|
|
|
|
This method indicates no logging is going to be used. It flushes any entries in
|
|
the internal buffer, and sets a flag to ensure no further data is put there.
|
|
|
|
=cut
|
|
sub nofile
|
|
{

my $self = shift;

|
|
|
|
$self->{buffer} = [];
|
|
}
|
|
|
|
=head2 _logopen
|
|
|
|
Internal method. Returns true if the log file is open, false otherwise.
|
|
|
|
=cut
|
|
sub _logopen
|
|
{
|
|
my $self = shift;

|
|
return 0;
|
|
}
|
|
|
|
=head2 debug info warn fatal
|
|
|
|
These four methods are wrappers to _log. They provide the actual interface for
|
|
logging data.
|
|
|
|
=cut
|
|
sub debug { my $self = shift; $self->_log("debug", @_); }
|
|
sub info { my $self = shift; $self->_log("info" , @_); }

|
|
sub fatal { my $self = shift; $self->_log("fatal", @_); }
|
|
|
|
=head2 _log
|
|
|
|
This is an internal method called by the logging functions. It generates a
|
|
timestamp and pushes the logged line either to file, or internal buffer.
|
|
|
|
=cut
|
|
sub _log
|
|

|
|
}
|
|
}
|
|
|
|
=head2 DESTROY
|
|
|
|
This method simply closes the file handle if one is open
|
|
|
|
