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

# would have two bad choices: it could either send information about all |
|
# 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 |

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; |
|
my $filename = 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; |
|
my $filename = shift; |
|
|
|

|
{ |
|
open $self->{fh}, ">>", $filename or die("Couldn't open '$filename' for writing : $!"); |
|
} |

|
|

|
|
|
while ( my $line = shift @{$self->{buffer}} ) |
|
{ |
|
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->{nolog} = 1; |
|
|
|
return unless ( defined ( $self->{buffer} ) and ref $self->{buffer} eq "ARRAY" ); |
|
|
|
$self->{buffer} = []; |
|
} |
|
|
|
=head2 _logopen |
|
|
|
Internal method. Returns true if the log file is open, false otherwise. |
|
|
|
=cut |
|
sub _logopen |
|
{ |
|
my $self = shift; |
|

|
- A reference to hash that contains a "tag" that is the |

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. |

# one fork (perhaps one directory at a time, without recursion, |

# changed back, confusing anything trying to interpret |
