wireproto: port heads command to wire protocol v2
After much thought and consideration, wire protocol version 2's
commands will be defined in different functions from the existing
commands. This will make it easier to implement these commands
because it won't require shoehorning things like response formatting
and argument declaration into the same APIs.
For example, wire protocol version 1 requires that commands declare
a fixed and ordered list of argument names. It isn't really possible
to insert new arguments or have optional arguments without
breaking backwards compatibility. Wire protocol version 2, however,
uses CBOR maps for passing arguments. So arguments a) can be
optional b) can be added without BC c) can be strongly typed.
This commit starts our trek towards reimplementing the wire protocol
for version 2 with the heads command. It is pretty similar to the
existing heads command. One added feature is it can be told to
operate on only public phase changesets. This is useful for
making discovery faster when a repo has tens of thousands of
draft phase heads (such as Mozilla's "try" repository).
The HTTPv2 server-side protocol has had its `getargs()` implementation
updated to reflect that arguments are a map and not a list.

#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 >> $HGRCPATH <<EOF > [lfs] > url=file:$TESTTMP/dummy-remote/ > 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.
