VCP-0.3

Changes for version 0.3

VSS Support added
bin/vcp now errors out sooner on command line errors to avoid misconstruing poorly typed parameters early in @ARGV as errors in later parameters. Unkown schemes were proving troublesome.
VCP::Dest
- "presort" sort key added. This must be the first sort key. It is on by default, and enables two-phased presort & merge strategy by default. This is engaged by using the sort key "presort" first in the sort spec.
- avgcommenttime revision sort key to allow revs with the same timestamp to be sorted by the agv timestamps for the comments they bear, so as to group them with other revisions with the same comment before or after the current timestamp value.
- if a field is present in only some revisions, it will usually be ignored in the sort spec (otherwise unstable sorts can result). These are called "sporadic" fields. This only affects sorting, not payload data.
- Missing (undef) comment fields are now treated as "" for base revisions (which never have comments), to keep base revisions from causing comment fields to be sporadic. This only affects sorting, not payload data.
- Missing (undef) time fields are now treated as 0 for base revisions (which never have comments), to keep base revisions from causing comment fields to be sporadic. This only affects sorting, not payload data.
- Sort keys are no longer stored in the VCP::Rev; they need to be manipulated by VCP::Dest and I don't want to complicate VCP::Rev's internal-use-only metadata, so I removed it.
VCP::Dest::p4
- Doesn't error out when asked to delete an already-deleted file. This was happening due to Source::vss's need to always flag deleted files for incremental exports because it can't tell if a file was deleted before or since the beginning of the export.
VCP::Dest::revml
- Allows several more output fields to be not-present, since VSS provides scarce metadata at times (especially for Delete operations).
VCP::Patch
- Ignores lineends when checking to see if a patch is being applied to the appropriate file.
- Some (all too verbose) debugging removed.
VCP::Plugin
- Emits Win32-friendlt quotes ("" instead of '') when debugging commands. This allows debugging output to be copy-n-pasted to the command line.
- Nascent support for a "stderr_filter" option when running commands. This is to make it easier to have per-command custom stderr filters. A fair amount of VSS code and perhaps some CVS code should be upgraded to use this instead of the current "save in a temp, set new, run command, restore temp" process.
VCP::Rev
- Doesn't complain about undeleted files if $ENV{VCPNODELETE}
- The SORT_KEY field is deprecated, will be removed soon.
- base_revify() added so that Source::vss can parse the log entry for a base revision, then notice that it is a base revision and remove extraneous fields.
- as_string(), which is used in a lot of debugging output, now prints out the first 32 characters of the comment field. This is invaluable when debugging without change numbers and rational (IMHO) rev_ids (as with VSS).
- $ENV{VCPNODELETE} now prevents individual file deletes, too.
- VCP::Source
  - handle time strings with single digits (xx/y/z)
- Remove a Win32ism (.exe no longer needed on filename, IPC::Run is better about this now).
VCP::Utils::p4
- protect program exit when running a subprocess in an END block.
- Remove a Win32ism (.exe no longer needed on filename, IPC::Run is better about this now).
- Workaround intermittant corrupted output from p4
- Failure to delete the working client from the p4 repository is no longer fatal (why die() out of an end block and cause other cleanup not to occur).
Remove stray file (throwaway script) "beatonit" from MANIFEST.
revml.dtd
- Allow VSS' almost metadataless <delete/>s.
