[RFCv2 00/12] Foreign VCS helper program for CVS repositories

Hi,

Here is a resend of the jh/vcs-cvs topic in 'pu'. This series is based on
the jh/notes topic in current 'pu', but is NOT based on the db/transport-shim
topic. As a consequence of this, the series now contains 3 more patches that
were part of the original db/foreign-scm topic.

Also, I expect that Barkalow will at some point send an updated
db/foreign-scm topic, which will invalidate parts of - or the whole of -
this patch series. I expect to rebase and resend this topic when the
updated db/foreign-scm appears, but since I am away for the next week,
I still send this series now, to reflect the current (unfinished) state.

The 7 first patches are a resend of Barkalow's original foreign-scm topic,
or at least enough of it to support the rest of this series.

Next, there are 3 patches tweaking and expanding the foreign-vcs API (with
corresponding implementations in the foreign transport code) to adjust for
the CVS helper's needs.

The final 2 patches add the git-vcs-cvs helper program that implements the
fetch/import of objects from a local or remote CVS repository, along with
selftests for verifying its correctness in some simple cases.


Changes since the last iteration:
- Added 3 more patches from the db/foreign-scm topic, caused by rebase.
- The patch with preliminary refactoring in fast-import.c is gone.
- The patch teaching fast-import to import notes has been moved to jh/notes.
- The CVS helper is updated to use the new 'notemodify' fast-import command.


Daniel Barkalow (7):
  Allow late reporting of fetched hashes
  Document details of transport function APIs
  Add option for using a foreign VCS
  Add specification of git-vcs-* helper programs
  Use a function to determine whether a remote is valid
  Allow programs to not depend on remotes having urls
  Add a transport implementation using git-vcs-* helpers

Johan Herland (5):
  Preliminary clarifications to git-vcs documentation
  Teach foreign transport code to perform the "capabilities" command
  Introduce a 'marks <filename>' feature to the foreign transport code
  First draft of CVS importer using the foreign-scm machinery
  Add simple test cases of git-vcs-cvs functionality
