Like I said up-thread, I'm happy to mentor someone through a `hg debugcgiweb` or something that would make it easier to use hg as a CGI script that would be appropriate for exposing to HTTP. I'm not going to say I'll do that work because I frankly don't have the time. > Complex software products routinely depend on wrong assumptions. > > De-facto we have a situation that Phabricator requires a very old version of > Mercurial, and thus makes Mercurial look bad. Last I knew phabricator was pinning to an ancient hg specifically because they try to parse our wire protocol blindly without actually understanding our format evolution policy (we detect new capabilities and then use a new format), and then blamed /us/ when we changed a format they shouldn't have been claiming (in the capabilities network call) to support. So I suspect even if you fix this immediate issue, hg-on-phabricator will still be Very Broken unless they've gotten their act together about filtering capabilities to something their software can cope with. But I'm happy to mentor an easier cgi endpoint for things if someone has the energy. It just won't be me that has that energy. :) > > > Makarius _______________________________________________ Mercurial mailing list Mercurial@mercurial-scm.org https://www.mercurial-scm.org/mailman/listinfo/mercurial
