#testcases lfsremote-on lfsremote-off

#require serve

This test splits `hg serve` with and without using the extension into separate

tests cases.  The tests are broken down as follows, where "LFS"/"No-LFS"

indicates whether or not there are commits that use an LFS file, and "D"/"E"

indicates whether or not the extension is loaded.  The "X" cases are not tested

individually, because the lfs requirement causes the process to bail early if

the extension is disabled.

  $ hg init server

Skip the experimental.changegroup3=True config.  Failure to agree on this comes

first, and causes a "ValueError: no common changegroup version" or "abort:

HTTP Error 500: Internal Server Error", if the extension is only loaded on one

side.  If that *is* enabled, the subsequent failure is "abort: missing processor

for flag '0x2000'!" if the extension is only loaded on one side (possibly also

masked by the Internal Server Error message).
