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@nongnu.org ######################################################################### # # USER Configurables # # %bin_ext should be editable from the command line. # # NOTE: Each possible binary extension is listed as a Perl regexp # # The value associated with each regexp key is used to print a log # message when a binary file is found. my %bin_ext = ( '\.(?i)abs$' => "Absolute File", '\.(?i)bin$' => "Binary", '\.(?i)bit$' => "Bit File", '\.(?i)ol$' => "Compiler Output", '\.(?i)out$' => "Default Compiler Output", '\.(?i)ln$' => "Linker Output", '\.(?i)lob$' => "Lint Output", '\.(?i)zob$' => "DBCO Object", '\.(?i)mim$' => "MIME File", '\.(?i)dwi$' => "DWI File", '\.(?i)iop$' => "IOP File", '\.(?i)btl$' => "", '\.(?i)rom$' => "ROM File", '\.(?i)a07$' => "", '\.(?i)lib$' => "DOS/Wintel/Netware Compiler Library", '\.(?i)lif$' => "Netware Binary File", '\.(?i)(com|exe)$' => "DOS/Wintel Executable", '\.(?i)tco$' => "", '\.(?i)obj$' => "DOS/Wintel Compiler Object", '\.(?i)res$' => "DOS/Wintel Resource File", '\.(?i)ico$' => "DOS/Wintel Icon File", '\.(?i)nlm$' => "Netware Loadable Module", '\.(?i)t8u$' => "", '\.(?i)c8u$' => "", '\.(?i)lku$' => "", '\.(?i)pdf$' => "Adobe Acrobat Portable Document Format", '\.(?i)doc$' => "MS Word Document", '\.(?i)dot$' => "MS Word Document Template", '\.(?i)pps$' => "MS PowerPoint Presentation", '\.(?i)xls$' => "MS Excel Spreadsheet", '\.(?i)(bmp|gif|jfif|jpeg|jpg|png|tif|tiff|xbm)$' => "Image", '\.(?i)(bz2|gz|tgz|zip)$' => "Compressed File", '\.(?i)dll$' => "DOS/Wintel Dynamically Linked Library", '\.(?i)class$' => "Compliled Java Class File", '\.(?i)jar$' => "Java Archive File", '\.(?i)war$' => "Java Web Archive File", '\.o$' => "UNIX Compiler Object", '\.a$' => "UNIX Compiler Library", '\.so(\.\d+\.\d+)?$' => "UNIX Shared Library" ); # The binaries this script is dependant on: my @bin_dependancies = ("vcs", "vlog", "rcs", "ci"); # Where we should put temporary files my $tmpdir = $ENV{TMPDIR} ? $ENV{TMPDIR} : "/var/tmp"; # We use these... use strict; use Cwd; use File::Basename; # For the usage message. use File::Copy; use File::Path; use IO::File; use Getopt::Long; $Getopt::Long::bundling = 1; my $program = basename $0; my $usage = "\ usage: $program -h $program [-lt] [-i vcsid] [-r flat|leaf] [-p flat|leaf] [-x rcs_extension] [-v none|locks|exists] [options] [path...] "; my $help = "\ $usage ---------------------------- ----------------------------------- -h | --Help Print this text General Settings ---------------------------- ----------------------------------- --Recurse Recurse through directories (default) -l | --NORecurse Process only . --Errorfiles Save a count of conversion errors in the RCS archive directory (default) (unimplemented) --NOErrorfiles Don't save a count of conversion errors (unimplemented) ( -m | --Mode ) Convert Convert PVCS files to RCS files (default) ( -m | --Mode ) Verify Perform verification ONLY (unimplemented) ( -v | --VERIfy ) None Always replace existing RCS files ( -v | --VERIfy ) LOCKS Same as exists unless a #conv.done file exists in the RCS directory.
