package VCP::Utils::vss ; =head1 NAME VCP::Utils::vss - utilities for dealing with the vss command =head1 SYNOPSIS use VCP::Utils::vss ; =head1 DESCRIPTION A mix-in class providing methods shared by VCP::Source::vss and VCP::Dest::vss, mostly wrappers for calling the vss command. =cut use strict ; use Carp ; use File::Spec ; use File::Temp qw( mktemp ) ; use VCP::Debug qw( :debug ) ; use VCP::Logger qw( lg pr_doing pr_done pr_done_failed ); use VCP::Utils qw( empty start_dir ) ; =head1 METHODS =item ssdir The location of the VSS database, if set in either the SSDIR environment variable or in the source or destination specification. =cut sub ssdir { my $self = shift; defined $self->repo_server ? File::Spec->rel2abs( $self->repo_server, start_dir ) : $ENV{SSDIR}; } =item ssuser The location of the VSS database, if set in either the SSUSER environment variable or in the source or destination specification. =cut sub ssuser { my $self = shift; defined $self->repo_user ? $self->repo_user : $ENV{SSUSER}; } =item ss Calls the vss command with the appropriate vssroot option. TODO: See if we can use two different users to do vss->vss. Not sure if VSS sets the cp and workfold per machine or per user. =cut sub ss { my $self = shift ; my $args = shift ; my $cmd = shift @$args; my $user = $self->repo_user; my @Y_arg; push @Y_arg, "-Y$user" unless empty $user; local $ENV{SSPWD} = $self->repo_password if defined $self->repo_password; local $ENV{SSDIR} = $self->ssdir if defined $self->repo_server; lg "SSDIR=$ENV{SSDIR}"; my @I_arg; push @I_arg, "-I-" unless grep /^-I/, @$args; my @O_arg; ## Forcing VSS to emit to a file with its -O@foo.txt syntax ## prevents it from wrapping at 80 cols.

# | Change | User | Description | Committed | |
---|---|---|---|---|---|
#16 | 3850 | Barrie Slaymaker | - No longer stores all revs in memory | ||
#15 | 3834 | Barrie Slaymaker | - Remove support for old progress bar | ||
#14 | 3739 | Barrie Slaymaker | - VCP undo of Rename/Restore now occurs even when a BUG surfaces | ||
#13 | 3705 | Barrie Slaymaker |
- VCP::Source::vss can parse all of real_vss_1 - VCP::Source::vss --undocheckout option added |
||
#12 | 3682 | Barrie Slaymaker |
- VCP::Source::vss now survives more VCC oddness I don't understand - Directory names with trailing slashes no longer give SS.EXE the fits |
||
#11 | 3681 | Barrie Slaymaker | - VCP now scans much more of real_vss_1 and converts it to revml | ||
#10 | 3677 | Barrie Slaymaker |
- rev_root sanity check is now case insensitive on Win32 - Parens in source filespecs are now treated as regular characters, not capture groups - ** is not treated as '...' |
||
#9 | 3667 | Barrie Slaymaker |
- VCP-Source-vss.stml now has atomic questions instead of asking for a command-line-like vss: spec |
||
#8 | 3510 | Barrie Slaymaker | - VSS --continue and branching support | ||
#7 | 3433 | Barrie Slaymaker | - Merge in new VSS code. | ||
#6 | 3286 | John Fetkovich |
In 'sub new' constructors of vss source and dest with a new sub, parse_vss_repo_spec in Utils/vss.pm. This also will set the repo_id. Only call parse_vss_repo_spec if the $spec is non-empty. |
||
#5 | 3155 | Barrie Slaymaker |
Convert to logging using VCP::Logger to reduce stdout/err spew. Simplify & speed up debugging quite a bit. Provide more verbose information in logs. Print to STDERR progress reports to keep users from wondering what's going on. Breaks test; halfway through upgrading run3() to an inline function for speed and for VCP specific features. |
||
#4 | 2933 | John Fetkovich | Added calls to empty() | ||
#3 | 1855 | Barrie Slaymaker |
Major VSS checkin. Works on Win32 |
||
#2 | 1822 | Barrie Slaymaker |
Get all other tests passing but VSS. Add agvcommenttime sort field. |
||
#1 | 1810 | Barrie Slaymaker | Preliminary VSS checkin |
