Even better, Shawn, if this LGTY I will reroll the series implementing this. >>> I think we want to declare features for import-marks and export-marks >>> and define these as paths to local files which store a VCS specific >>> formatted mapping of fast-import mark numbers to VCS labels. > > Explicitly specifying the local path names worries me though.

I think the stream should not have to change, which works if you define the files to be local to the repo being exported to. That is, in git the line "feature export-marks=out.marks" would result in a marks file located in "/path/to/repo/.git/fast-import/out.marks". Or is that not what you mean? > +1.

It is not possible to change the semantics using options though, what kind of bugs could arise this way? > I don't think options should be permitted to change import behavior. In > other words, we should actively discourage vcs-specific streams Sounds fair, I reckon that a wiki in addition to the vcs-fast-import-devs list would not hurt :). -- Cheers, Sverre Rabbelier _______________________________________________ Mailing list: https://launchpad.net/~vcs-fast-import-devs Post to : email@example.com Unsubscribe : https://launchpad.net/~vcs-fast-import-devs More help : https://help.launchpad.net/ListHelp
