# FUNCTION:
# To recursively walk through a PVCS archive directory tree (archives
# located in VCS/ or vcs/ subdirectories) and convert them to RCS archives.
# The RCS archive name is the PVCS workfile name with ",v" appended.
#
# SYNTAX:
# pvcs_to_rcs.pl --help
#
# where -l indicates the operation is to be performed only in the current
# directory (no recursion)
#
# EXAMPLE:
# pvcs_to_rcs
# Would walk through every VCS or vcs subdir starting at the current directory,
# and produce corresponding RCS archives one level above the VCS or vcs subdir.
# (VCS/../RCS/)
#
# NOTES:
# * This script performs little error checking and logging
# (i.e. USE AT YOUR OWN RISK)
# * This script was last tested using ActiveState's port of Perl 5.005_02
# (internalcut #507) under Win95, though it does compile under Perl-5.00404
# for Solaris 2.4 run on a Solaris 2.6 system. The script crashed
# occasionally under ActiveState's port of Perl 5.003_07 but this stopped
# happening with the update so if you are having problems, try updating Perl.
# Upgrading to cut #507 also seemed to coincide with a large speed
# improvement, so try and keep up, hey? :) It was executed from MKS's
# UNIX tools version 6.1 for Win32's sh. ALWAYS redirect your output to
# a log!!!
# * PVCS archives are left intact
# * RCS archives are created in VCS/../RCS/ (or ./RCS using '-pflat')
# * Branch labels in this script will be attached to the CVS magic
# revision number. For branch a.b.c of a particular file, this means
# the label will be attached to revision a.b.0.c of the converted
# file. If you use the TrunkTip (1.*) label, be aware that it will convert
# to RCS revision 0.1, which is useless to RCS and CVS. You'll probably
# have to delete these.
# * All revisions are saved with correct "metadata" (i.e. check-in date,
# author, and log message). Any blank log message is replaced with
# "no comment". This is because RCS does not allow non-interactive
# check in of a new revision without a comment string.
# * Revision numbers are incremented by 1 during the conversion (since
# RCS does not allow revision 1.0).
# * All converted branch numbers are even (the CVS paradigm)
# * Version labels are assigned to the appropriate (incremented) revision
# numbers. PVCS allows spaces and periods in version labels while RCS
# does not. A global search and replace converts " " and "." to "_"
# There may be other cases that ought to be added.
# * Any working (checked-out) copies of PVCS archives
# within the VCS/../ or vcs/../ (or possibly ./ with '-pflat')
# will be deleted (or overwritten) depending on your mode of
# operation since the current ./ is used in the checkout of each revision.
# I suppose if development continues these files could be redirected to
# temp space rather than ./ .
# * Locks on PVCS archives should be removed (or the workfiles should be
# checked-in) prior to conversion, although the script will blaze through
# the archive nonetheless (But you would lose any checked out revision(s))
# * The -kb option is added to the RCS archive for workfiles with the following
# extensions: .bin .out .btl .rom .a07 .lib .exe .tco .obj .t8u .c8u .o .lku
# .a and a few others. The %bin_ext variable holds these values in regexp
# form.
# * the --force-binary option can be used to convert binary files which don't
# have proper extensions, but I'd *probably* edit the %bin_ext variable.
# * This script will abort occasionally with the error "invalid revision
# number". This is known to happen when a revision comment has
# /^\s*Rev/ (Perl regexp notation) in it. Fix the comment and start over.
# (The directory locks and existance checking make this a fairly quick
# process.)
# * This script writes lockfiles in the RCS/ directories. It will also not
# convert an archive if it finds the RCS Archive existant in the RCS/
# directory. This enables the conversion to quickly pick up where it left
# off after errors or interrupts occur. If you interrupt the script make
# sure you delete the last RCS Archive File which was being written.
# If you recieve the "Invalid revision number" error, then the RCS archive
# file for that particular PVCS file will not have been created yet.
# * This script will not create lockfiles when processing single
# filenames passed into the script, for hopefully obvious reasons.
# (lockfiles lock directories - DRP)
# * Log the output to a file. That makes it real easy to grep for errors
# later. (grep for "^[ \t]*(rcs|ci):" and be aware I might have missed
# a few cases (get? vcs?) !!!) *** Also note that this script will
# exibit some harmless RCS errors. Namely, it will attempt to lock
# branches which haven't been created yet. ***
# * I tried to keep the error and warning info up to date, but it seems
# to mean very little. This script almost always exits with a warning
# or an error that didn't seem to cause any harm. I didn't trace it
# and our imported source checks out and builds...
# It is probably happening when trying to convert empty directories
# or read files (possibly checked out workfiles ) which are not
# pvcs_archives.
# * You must use the -pflat option when processing single filenames
# passed as arguments to the script. This is probably a bug.
# * questions, comments, additions can be sent to info-cvs@nongnu.org
