    bundle2: make server.bundle2.stream default to True · 4bd6e444c76f
    Anton Shestakov authored
    Support for bundle2 streaming clones has been shipped in Mercurial 4.5
    (7eedbd5d4880), but was never activated by default. It's time to have more
    people use it. The new format allows streaming clones to transport cache
    (hooray for speed) and phaseroots (fixes phase-related issues).
    
    Changes in tests:
    
    bundle2 capabilities now have "stream=v2" (plus a '\n' as a separator) and
    therefore take 14 bytes more: "%0Astream%3Dv2". Tip for tests that have data
    encoded with CBOR: 0xd3 - 0xc5 = 14.
    
    $USUAL_BUNDLE2_CAPS$ replaces $USUAL_BUNDLE2_CAPS_SERVER$, which is the same
    thing, but without "stream=v2".
    
    Since streaming clones now also transfer caches, the reported byte and file
    counts are higher (e.g. 816 bytes in 9 files instead of 613 bytes in 4 files,
    a bit of --debug and manual math confirms that the caches take these extra 203
    bytes in 5 files).
