comparison mercurial/changegroup.py @ 37132:a54113fcc8c9

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
lfs: move the 'supportedoutgoingversions' handling to changegroup.py This handling already exists here for the narrow extension. We still need to either figure out how to enable changegroup v3 without the extension, or figure out how to let the server detect that the client doesn't have it loaded, and emit a user friendly error[1]. I can't tell if D1944 is the appropriate vehicle for the latter. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2018-January/109550.html
