No, cvs-fast-export does not have --export-marks. It doesn't generate the SHA1s that would require. Even if it did, it's not clear how that would help.I was thinking about how the following part of git-fast-export `--import-marks=<file>` Any commits that have already been marked will not be exported again. If the backend uses a similar --import-marks file, this allows for incremental bidirectional exporting of the repository by keeping the marks the same across runs.
I understand that. But it's not relevant - cvs-fast-import doesn't know about git SHA1s, and cannot.
How cvs-fast-export know where to start exporting from in incremental mode?
You give it a cutoff date. This is the same way cvsps-2.x and 3.x worked, and it's what the cvsimport wrapper expects to pass down.
BTW. does cvs-fast-export support incremental *output*, or does it perform also incremental *work*?
As I tried to explain previously in my response to John Herland, it's incremental output only. There is *no* CVS exporter known to me, or him, that supports incremental work. That would be at best be impractically difficult; given CVS's limitations it may be actually impossible. I wouldn't bet against impossible.
Anyway, that might mean that generic fast-import stream based incremental (i.e. supporting proper thin fetch) remote helper is out of question, perhaps writing one for cvs / cvs-fe would bring incremental import from CVS to git?
