package VCP::Source::p4 ; =head1 NAME VCP::Source::p4 - A Perforce p4 repository source =head1 SYNOPSIS vcp p4://depot/...@10 # all files after change 10 applied vcp p4://depot/...@1,10 # changes 1..10 vcp p4://depot/...@-2,10 # changes 8..10 vcp p4://depot/...@1,#head # changes 1..#head vcp p4://depot/...@-2,#head # changes 8..10 vcp p4:...@-2,#head # changes 8..10, if only one depot To specify a user name of 'user', P4PASSWD 'pass', and port 'host:1666', use this syntax: vcp p4:user(client)password@host:1666:files Note: the password will be passed in the environment variable P4PASSWD so it shouldn't show up in error messages. This means that a password specified in a P4CONFIG file will override the password you set on the command line. This is a bug. User, client and the server string will be passed as command line options to make them show up in error output. You may use the P4... environment variables instead of any or all of the fields in the p4: repository specification. The repository spec overrides the environment variables. =head1 DESCRIPTION Driver to allow L to extract files from a L repository. Note that not all metadata is extracted: users, clients and job tracking information is not exported, and only label names are exported. Also, the 'time' and 'mod_time' attributes will lose precision, since p4 doesn't report them down to the minute. Hmmm, seems like p4 never sets a true mod_time. It gets set to either the submit time or the sync time. From C: modtime Causes 'p4 sync' to force modification time to when the file was submitted. nomodtime * Leaves modification time set to when the file was fetched. =head1 OPTIONS =over =item -b, --bootstrap -b '...' --bootstrap='...' -b file1[,file2[,...]] --bootstrap=file1[,file2[,...]] (the C<...> there is three periods, a L wildcard borrowed from C path syntax). Forces bootstrap mode for an entire export (C<-b ...>) or for certain files. Filenames may contain wildcards, see L for details on what wildcards are accepted. This switch controls how the first revision of a file is exported. A bootstrap export of a file contains the entire contents of the first revision exported. This is automatic if the export contains the first revision of a file in the SCM. In contrast to a bootstrap export of a file, an incremental export of a file contains a digest of the revision preceding the first revision in the revision range, followed by a delta record between that revision and the first revision. This allows the destination import function to make sure that the incremental export begins where the last export left off. This option is necessary when exporting only more recent revisions from a repository. =item --continue Starts this transfer where the last one (to the same destination) left off. This uses the destination's state database to detect what was transferred last time and to begin this transfer where that one left off. =for implementor This is defined and accessed in a base class. =item --follow-branch-into Causes VCP to notice "branch into" messages in the output of p4's filelog command and, if the file that is the target of the p4 integrate (branch) command is revision number #1, add the target to the list of exported files. This usually needs a --rev-root option to set the rev root to be high enough in the directory tree to include all branches (it's an error to export a file that is not under the rev root). =item -r, --rev-root Sets the "revisions" root of the source tree being extracted; without this option, VCP assumes that you are extracting the directory tree ending in the last path segment in the filespec without a wildcard. This allows you to specify a shorter root directory, which can be useful especially with --follow-branch-into, since branches may often lead off from the current directory to peer directories or even in to entirely different trees. The default C is the file spec up to the first path segment (directory name) containing a wildcard, so p4:/a/b/c... would have a rev root of C. In direct repository-to-repository transfers, this option should not be necessary, the destination filespec overrides it. =back =head1 BRANCHES VCP uses the "directory" name of each file as the file's branch_id. VCP ignores p4 branch specs for several reasons: =over =item 1 Branch specs are not version controlled, which means that you can't tell what a branch spec looked like when a branch was created. =item 2 Multiple branch specs can point to the same directory or even the same file. =item 3 branch specs are not necessary in managing a p4 repository. =back TODO: build a filter or VCP::Source::p4 option that allows p4 branch specifications to determine branch_ids. As the L chapter mentions, you can use a Map section in the transfer specification to extract meaningful Cs if you need to. =for test_script t/9*p4.t =cut $VERSION = 1.0 ; use strict ; use Carp ; use Fcntl qw( O_WRONLY O_CREAT ) ; use File::Basename; use VCP::Debug ":debug" ; use VCP::Logger qw( lg BUG pr ); use Regexp::Shellish qw( :all ) ; use VCP::Branch; use VCP::Branches; use VCP::Rev ; use base qw( VCP::Source VCP::Utils::p4 ) ; use fields ( 'P4_REPO_CLIENT', ## Set by p4_parse_repo_spec in VCP::Utils::p4 'P4_INFO', ## Results of the 'p4 info' command 'P4_LABEL_CACHE', ## ->{$name}->{$rev} is a list of labels for that rev # 'P4_LABELS', ## Array of labels from 'p4 labels' 'P4_MAX', ## The last change number needed 'P4_MIN', ## The first change number needed 'P4_FOLLOW_BRANCH_INTO', ## Whether or not to follow "branch-into" events 'P4_BRANCHES_TO_FOLLOW', ## Branches remaining to be parsed 'P4_FAKE_BRANCH_COUNTER', ## The current "fake" branch id.

Ignores branch specs for now. There may be an option to enable automatic use of branch specs because most are probably well behaved. However, in the event of a branch spec being altered after the original branch, this could lead to odd results. Not sure how useful branch specs are vs. how likely a problem this is to be. We may also want to support "external" branch specs to allow deleted branch specs to be used. =head1 SEE ALSO L, L. =head1 AUTHOR Barrie Slaymaker =head1 COPYRIGHT Copyright (c) 2000, 2001, 2002 Perforce Software, Inc.
