wireproto: implement capabilities for wire protocol v2
The capabilities mechanism for wire protocol version 2 represents a
clean break from version 1.
Instead of effectively exchanging a set of capabilities, we're
exchanging a rich data structure.
This data structure currently contains information about
every available command, including its accepted arguments. It also
contains information about supported compression formats.
Exposing information about supported commands will allow clients
to automatically generate bindings to the server. Clients will be
able to do things like detect when they are attempting to run a
command that isn't known to the server. Exposing the required
permissions to run a command can be used by clients to determine if
they have privileges to call a command before actually calling it.
We could potentially even have clients send credentials
preemptively without waiting for the server to deny the command
request. Lots of potential here.
The data returned by this command will likely evolve heavily. So we
shouldn't bikeshed the implementation just yet.

#testcases lfsremote-on lfsremote-off #require serve no-reposimplestore 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. . Server . .

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). $ cat >> $HGRCPATH <<EOF > [lfs] > usercache = null:// > threshold=10 > [web] > allow_push=* > push_ssl=False > EOF #if lfsremote-on $ hg --config extensions.lfs= -R server \ > serve -p $HGPORT -d --pid-file=hg.pid --errorlog=$TESTTMP/errors.log #else $ hg --config extensions.lfs=! -R server \ > serve -p $HGPORT -d --pid-file=hg.pid --errorlog=$TESTTMP/errors.log #endif $ cat hg.pid >> $DAEMON_PIDS $ hg clone -q http://localhost:$HGPORT client $ grep 'lfs' client/.hg/requires $SERVER_REQUIRES [1] -------------------------------------------------------------------------------- Case #1: client with non-lfs content and the extension disabled; server with non-lfs content, and the extension enabled. $ cd client $ echo 'non-lfs' > nonlfs.txt $ hg ci -Aqm 'non-lfs' $ grep 'lfs' .hg/requires $SERVER_REQUIRES [1] #if lfsremote-on $ hg push -q $ grep 'lfs' .hg/requires $SERVER_REQUIRES [1] $ hg clone -q http://localhost:$HGPORT $TESTTMP/client1_clone $ grep 'lfs' $TESTTMP/client1_clone/.hg/requires $SERVER_REQUIRES [1] $ hg init $TESTTMP/client1_pull $ hg -R $TESTTMP/client1_pull pull -q http://localhost:$HGPORT $ grep 'lfs' $TESTTMP/client1_pull/.hg/requires $SERVER_REQUIRES [1] $ hg identify http://localhost:$HGPORT d437e1d24fbd #endif -------------------------------------------------------------------------------- Case #2: client with non-lfs content and the extension enabled; server with non-lfs content, and the extension state controlled by #testcases. $ cat >> $HGRCPATH <<EOF > [extensions] > lfs = > EOF $ echo 'non-lfs' > nonlfs2.txt $ hg ci -Aqm 'non-lfs file with lfs client' Since no lfs content has been added yet, the push is allowed, even when the extension is not enabled remotely. $ hg push -q $ grep 'lfs' .hg/requires $SERVER_REQUIRES [1] $ hg clone -q http://localhost:$HGPORT $TESTTMP/client2_clone $ grep 'lfs' $TESTTMP/client2_clone/.hg/requires $SERVER_REQUIRES [1] $ hg init $TESTTMP/client2_pull $ hg -R $TESTTMP/client2_pull pull -q http://localhost:$HGPORT $ grep 'lfs' $TESTTMP/client2_pull/.hg/requires $SERVER_REQUIRES [1] $ hg identify http://localhost:$HGPORT 1477875038c6 -------------------------------------------------------------------------------- Case #3: client with lfs content and the extension enabled; server with non-lfs content, and the extension state controlled by #testcases.
