This series is a first draft towards implementing a foreign VCS helper program for CVS.
It is based on the 'db/foreign-scm' and 'jh/notes' topics in 'pu'. As such, this patch series should apply cleanly to current 'pu'.
The first 4 patches supply the necessary parts of Daniel Barkalow's foreign-scm topic that has not yet been merged to 'pu' (i.e. everything remaining in Daniel's original patch series, except the p4-specific stuff).
The next 2 patches add some functionality to git fast-import, for facilitating the import of 'notes' objects (this is a _much_ faster way to generate/import notes than invoking "git notes edit -m MSG" for each note).
Next, there are 3 patches tweaking and expanding the git-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. This is a first RFC/draft of this helper program, and will hopefully grow along with the foreign-scm feature itself until it provides a compelling alternative to "git cvsimport" and "git cvsexportcommit".
Daniel Barkalow (4): 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 (7): Refactor path name parsing into new function: get_path_str() Add support for mark references as path names 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
