- # 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.)
- # Binary files which do not have their mode set properly are likely to look
- # corrupted on initial checkout and use, but using
- # `cvs admin -kb <workfilename>' to retroactively change the RCS keyword
- # substitution mode of the file to binary (and refreshing the files in any
- # local workspaces they are checked out in: `rm <workfilename>; update'
- # should do the trick) should end any problems with the original import.
- # If anyone has checked in changes since the import, those revisions may
- # be corrupted in the imported archive and therefore those changes (commits
- # of corrupted data) may need to be backed out.
- # * 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@gnu.org
