The code of git-cvsserver currently has several hard-coded 20 and 40 constants that are the length of SHA-1. When parsing the configuration file, read the extensions.objectformat configuration setting as well as CVS-related ones and adjust the hash sizes accordingly. Use these computed values in all the places we match object IDs.

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

|
{
|
|
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
|
|
{

|
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 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
|
|
|
|
=cut

actual revision (one of the below). TODO: Also allow it to

specify a "date" in the hash.
|
|
- undef, to refer to the latest version on the main branch.
|
|
- Full CVS client revision number (mapped to integer in DB, without the
|
|
"1." prefix),
|
|
- Complex CVS-compatible "special" revision number for
|
|
non-linear history (see comment below)
|
|
- git commit sha1 hash
|
|
- branch or tag name

# Overview of CVS revision numbers:
|
|
#
|
|
# General CVS numbering scheme:
|
|
# - Basic mainline branch numbers: "1.1", "1.2", "1.3", etc.
|
|
# - Result of "cvs checkin -r" (possible, but not really
|
|
# recommended): "2.1", "2.2", etc
|
|
# - Branch tag: "1.2.0.n", where "1.2" is revision it was branched
|
|
# from, "0" is a magic placeholder that identifies it as a
|
|
# branch tag instead of a version tag, and n is 2 times the
|
|
# branch number off of "1.2", starting with "2".
|
|
# - Version on a branch: "1.2.n.x", where "1.2" is branch-from, "n"
|
|
# is branch number off of "1.2" (like n above), and "x" is
|
|
# the version number on the branch.
|
|
# - Branches can branch off of branches: "1.3.2.7.4.1" (even number
|
|
# of components).
|
|
# - Odd "n"s are used by "vendor branches" that result
|
|
# from "cvs import". Vendor branches have additional
|
|
# strangeness in the sense that the main rcs "head" of the main
|
|
# branch will (temporarily until first normal commit) point
|
|
# to the version on the vendor branch, rather than the actual
|
|
# main branch. (FUTURE: This may provide an opportunity
|
|
# to use "strange" revision numbers for fast-forward-merged
|
|
# branch tip when CVS client is asking for the main branch.)
|
|
#
|
|
# git-cvsserver CVS-compatible special numbering schemes:
|
|
# - Currently git-cvsserver only tries to be identical to CVS for
|
|
# simple "1.x" numbers on the "main" branch (as identified
|
|
# by the module name that was originally cvs checkout'ed).
|
|
# - The database only stores the "x" part, for historical reasons.
|
|
# But most of the rest of the cvsserver preserves
|
|
# and thinks using the full revision number.
|
|
# - To handle non-linear history, it uses a version of the form
|
|
# "2.1.1.2000.b.b.b."..., where the 2.1.1.2000 is to help uniquely
|
|
# identify this as a special revision number, and there are
|
|
# 20 b's that together encode the sha1 git commit from which
|
|
# this version of this file originated. Each b is
|
|
# the numerical value of the corresponding byte plus
|
|
# 100.
|
|
# - "plus 100" avoids "0"s, and also reduces the
|
|
# likelihood of a collision in the case that someone someday
|
|
# writes an import tool that tries to preserve original
|
|
# CVS revision numbers, and the original CVS data had done
|
|
# lots of branches off of branches and other strangeness to
|
|
# end up with a real version number that just happens to look
|
|
# like this special revision number form. Also, if needed
|
|
# there are several ways to extend/identify alternative encodings
|
|
# within the "2.1.1.2000" part if necessary.
|
|
# - Unlike real CVS revisions, you can't really reconstruct what
|
|
# relation a revision of this form has to other revisions.
|
|
# - FUTURE: TODO: Rework database somehow to make up and remember
|
|
# fully-CVS-compatible branches and branch version numbers.
