annotate upstream_keepalive.t @ 1888:cc13f7b098db

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Tests: avoid premature stream reset in h3_limit_req.t. STREAM and RESET_STREAM frames could be batched, which prevents the stream from being processed and changes the status code. The fix is to wait for the stream acknowledgment. Here we just look at the largest acknowledged, this should be enough for simple cases.
