[darcs-users] Q: language-c upstream repo

[Ivan Zakharyaschev]

Hi,

I went further recording patches and tags to the darcs-1 clone of 
language-c from Hackage (because I'm not sure which format will be 
preferred for requesting a pull to upstream) and wanting to push them to 
the darcs-2 clone at hub.darcs.net (becauase I want to save and publish 
them somewhere).

I want to share some notes about some encountered problems and how they 
were overcome.

Now I have again converted from my new state of the darcs-1 repo to 
darcs-2 and tried to push to (a clone of) the previous state darcs-2 
repo (at hub.darcs.net). And have had again that problem ("Failed to 
commute common patches").

After some attempts to convert "only a part of all the patches", I've 
discovered that obliterating my two new tags helps.

One of the tags did indeed not have all preceding patches as its 
dependency.

(And the tags were not very useful anyway, being more like branches which 
might receive further changes. And I'm going to solve the problem of 
saving branches by having several repos at hub.darcs.net.)

Best regards,
Ivan
