VCP::Dest::p4 - p4 destination driver

   vcp <source> p4:user:password@p4port:<dest>
   vcp <source> p4:user(client):password@p4port:<dest>
   vcp <source> p4:<dest>

The <dest> spec is a perforce repository spec and must begin with // and a depot name (//depot), not a local filesystem spec or a client spec. There should be a trailing /... specified.

If no user name, password, or port are given, the underlying p4 command will look at that standard environment variables.

VCP sets the environment P4PASSWD rather than giving p4 the password on the command line so it won't be logged in debugging or error messages. The other options are passed on the command line.

If no client name is given, a temporary client name like vcp_tmp_1234 will be created and used. The P4CLIENT environment variable will not be used. If an existing client name is given, the named client spec will be saved off, altered, used, and restored. If the client was created for this import, it will be deleted when complete, regardless of whether the client was specified by the user or was randomly generated. WARNING: If perl coredumps or is killed with a signal that prevents cleanuplike a SIGKILL (9)--the the client deletion or restoral will not occur. The client view is not saved on disk, either, so back it up manually if you care.

THE CLIENT SAVE/RESTORE FEATURE IS EXPERIMENTAL AND MAY CHANGE BASED ON USER FEEDBACK.

VCP::Dest::p4 attempts change set aggregation by sorting incoming revisions. See rev_cmp_sub in VCP::Dest for the order in which revisions are sorted. Once sorted, a change is submitted whenever the change number (if present) changes, the comment (if present) changes, or a new rev of a file with the same name as a revision that's pending. THIS IS EXPERIMENTAL, PLEASE DOUBLE CHECK EVERYTHING!

If the P4::Client Perl module is installed, this will be used instead of the p4 command line utility. If this causes undesirable results, set the environment variable VCPP4API equal to 0 (zero).

--run-p4d

Runs a p4d instance in the directory indicated by repo_server (use a directory path rather than a host name). If repo_server contains a port, that port will be used, otherwise a random port will be used. Dies unless the directory exists and contains files matching db.* (to help prevent unexpected initializing of empty directories). VCP will kill this p4d when it's done.

--init-p4d

Initializes a directory and starts a p4d in it on the given port. Refuses to init a non-empty directory. In this case the p4port portion of the destination specification must point to a directory; and the port, if present, will be used for the port (otherwise a randomized port number other than p4d's 1666 default will be used.) A temporary p4d will be started that should be shut down upon process exit. If the process does not exit cleanly (for instance, if sent the QUIT signal), this shutdown may not occur.

--delete-p4d-dir

If CW--init-p4d is passed and the target directory is not empty, it will be removed before running the p4d. THIS IS DANGEROUS AND SHOULD ONLY BE USED IN TEST ENVIRONMENTS.

--change-branch-rev-1

Some SCMs don't create a branch of a file until there is actually a change made to that file. So the first revision of a file on a branch is different from its parent on the main branch. Normally, p4 does not work this way: rev #1 of a branched file is a very inexpensive copy of the parent revision: you do a p4 integrate, submit, edit, submit sequence to branch a file and introduce it's changes. This option forces VCP to do a p4 integrate, add, submit sequence to branch files, thus capturing the branch and the file alterations in one change. Using this option allows VCP to more exactly model the source repository in the destination repository revision-for-revision, but leaves you with a perforce repository that may not be consistent with your work practices, so it is not the default behavior.

The p4 destination driver allows branching from deleted revisions of files to accomodate source repositories that allow it. It does this by branching from the revision prior to the deleted revision.

The p4 destination driver also allows the first revision of a file to be a deleted revision by forcing an empty add followed by a delete. CVS does this on the main trunk (rev 1.1 is dead, ie deleted) when you add a file on a branch.

repo_client

The p4 client name. This is an accessor for a data member in each class. The data member should be part of VCP::Utils::p4, but the fields pragma does not support multiple inheritance, so the accessor is here but all derived classes supporting this accessor must provide for a key named P4_REPO_CLIENT.
