(CC'ing darcs-users since it's a high-level decision on the design of Darcs repositories)
Here is the situation with _darcs/format: * there is a defined semantics : http://article.gmane.org/gmane.comp.version-control.darcs.devel/5393 * if we want to use this semantics for expressing that a repository is without working tree, we will run into a problem when we have a new kind of repositories : http://bugs.darcs.net/msg12892 * I proposed a change in the semantics : http://bugs.darcs.net/msg12949 , http://bugs.darcs.net/msg12948 * but I'm not sure if it is really a good solution… At least the change is harmless because as of now, Darcs is the only Darcs client and never writes "xxx|yyy" in _darcs/format . Why we should decide this change soon: * so that it can be put into darcs 2.5.1 * the feature no-working-tree repositories depends on this and it would be a shame to delay this because of lack of discussion Guillaume 2010/11/8 gh <b...@darcs.net>: > > gh <guilla...@gmail.com> added the comment: > >>> So, what about agreeing to interpret _darcs/format lines "A|B|..|X" >>> as: A is necessary to read the repos, and A, B ... to X are necessary >>> to write to it? >>> >> I thought about it, but this means breaking compatbility: we'd have to >> write it under _darcs/format2, and have _darcs/format be the single line >> 'format2'.
