RE: Request for comments on 'Extending CVS with offline/disconnected operations'

[Tamas Nagy]

Dear Derek,

No problem, at all, and thanks for the comments.

The reason for suggesting the 'disconnected merge' operation is to allow
working with different working folders, checked out e.g. under Windows
and Linux... I'm working on a multi-platform development project, and
need to frequently use/test/synchronize the changes among them. As the
CVS data structures allows this (completely?), why not having this
functionality as well in addition to add/remove/diff...

Do you think that these 'disconnected operations' could be implemented
outside as a wrapper script/external program or could be part of the cvs
executable?

After revising the 'e-mail transport layer' concept again, I'm not
confident whether it could be implemented efficiently, so I eliminiated
from the concept...

Best regards,
Tamas
