App-Pinto-0.065_01

Changes for version 0.065_01 - 2013-03-15

!! DEVELOPER RELEASE !!
This requires Pinto 0.065_01 (also a developer release).
IMPORTANT:
Bad news: This version of pinto is not compatible with *existing* repositories. To migrate, you'll need to create a new repository (using this version of pinto) and then "pull" all the distributons from your old repository into the new one. Repeat this process for each stack. Unfortunatley, you will loose your revision history. If you bug me about it, I'll write a script to automate this for you. I am thaljef@cpan.org.
Good news: This version of pinto has hooks to do future migrations automatically. So any repository you create with *this version* of pinto can be easily migrated to any future versions. I'm also pretty confident that the schema is now stable, so a migration will not be required for a while.
Also: several classes have been renamed or removed. I strongly recommend removing your current installation of Pinto and App::Pinto before installing this one. This will remove things that are no longer supported.
COMMANDS:
Many pinto commands have been been renamed, removed, or repurposed. Read the manual for each command to get full details. Here is a summary of changes:
New Commands:
The "props" command now shows AND sets configuration properties. The old "edit" command has been removed.
The new "default" command now takes the place of the --default option that existed on the (now defunct) "edit" command. Use the "default" command to mark the default stack. You can also choose to have no default stack in your repository, so that that every command will need to specify an explicit stack as an argument or option.
The new "kill" command takes the place of the "delete" command, which has been repurposed (see below). The command also accepts a --force option which kills the stack even if it is locked.
The "delete" command has been repurposed to permanently remove an archive (and all of its history) from the repository. This command is highly experimental. Be sure to read the caveats in the manual for this command.
The new "lock" command locks a stack so that its packages cannot be changed by future commands. This is useful for creating a read-only "tag" of a stack. There is also an "unlock" command.
The new "migrate" command migrates existing repositories to be compatible with the current version of Pinto. This will only work for repositories that were created with THIS version of Pinto or later. Contact thaljef@cpan.org if you need to migrate an older repository.
The new "register" command registers the packages within an existing archive on a stack. The archive must already be in the repository.
The new "unregister" command unregisters an archive from a stack, so that its packages will no longer appear in the index but the archive still remains in the repository.
Changed Commands:
The --stack option on the "init" command are no longer supported. Instead, you can specify the initial stack name as an argument. Also the --bare option is not supported either. When you create a repository with the "init" command the initial stack is now called "master".
The "copy" command no longer requires a commit message because the operation no longer creates an event in the revision history.
The "list" command no longer supports "%" to indicate that it should list the contents of all stacks. Instead, use the "diff" command for a more concise way to compare stacks.
The "log" command no longer takes a revision argument ("dev@673") because revisions are no longer identified by a sequence number. But a similar feature will be avialable in the next release. Also, the --details opton is not supported any more, but it will probably come back in the next release.
The --norecurse and --dryrun options have been renamed to --no-recurse and --dry-run on all commands that support them. This is to be consistent with other multi-word option names.
Removed Commands:
The "merge" and "revert" commands have been removed. At this time it just isn't clear how they should behave or even what their use case is. When I know more, I may bring these back.
The "edit" command is also gone. It's functionality has been replaced with the "props" command (see above).
The "blame" command has been removed. It never worked in the first place and fixing it is a low priority right now.
ENHANCEMENTS:
The version control system within Pinto has been redesigned to be simpler and faster. It is more Git-like and stores full snapshots of the stack at each revision (rather than just storing deltas). It also organizes history into a directed graph and uses unique non-sequential identifiers for each revision.
Due to the new version control system, the performance and scalability of Pinto is much improved. Benchmark tests show that common operations still perform well with as many as 10,000 commits (I estimate that is 10 years of work). And a Pinto repository can scale to 100,000 distributions with good performance too (that's almost all of CPAN).
The output of several commands are now colorized to improve readability. Use the --no-color option or set PINTO_NO_COLOR to disable color globally.
