There is no server-side record that you have done so. Fossil is, AFAIK, unique in that a single clone of a repository can be checked out any number of times. The connection between your machine and the server(s) is managed solely in terms of a repo db (a "clone" is a copy of such a repo db, created via the "clone" command). A checkout is simply one instance of "opening" a clone to gain access to its contents. Fossil neither needs to know, nor cares, whether a given checkout will be used for reading or writing. A user can ALWAYS check contents in to a fossil repo, but they MIGHT not be able to push any changes to a remote copy (depends on their permissions). > In fossil we use “add” which includes the file to a set of files that will > be commited in the next commit. > Nope - that's git's way of doing it (this is why i thought you were using git as a basis for comparison!). In fossil "add" is a one-time thing which is only necessary one time (ever) per file. (In git "add" is needed to "stage" the file for the next commit.) After a file is added, you use "checkin" to irrevocably commit those changes (along with any number of other changes) to fossil. There is no intermediary step of "pending for the next commit" in fossil. Contrariwise, any changes made in a checked-out copy are always considered "pending for the next commit" (for lack of a better phrase) until they are either committed or discarded (the checkout is deleted, "close"d, or otherwise revered to a pristine state). -- ----- stephan beal http://wanderinghorse.net/home/stephan/ "Freedom is sloppy.
