Merge branch 'jk/pkt-line-cleanup'
Clean up pkt-line API, implementation and its callers to make them more robust. * jk/pkt-line-cleanup: do not use GIT_TRACE_PACKET=3 in tests remote-curl: always parse incoming refs remote-curl: move ref-parsing code up in file remote-curl: pass buffer straight to get_remote_heads teach get_remote_heads to read from a memory buffer pkt-line: share buffer/descriptor reading implementation pkt-line: provide a LARGE_PACKET_MAX static buffer pkt-line: move LARGE_PACKET_MAX definition from sideband pkt-line: teach packet_read_line to chomp newlines pkt-line: provide a generic reading function with options pkt-line: drop safe_write function pkt-line: move a misplaced comment write_or_die: raise SIGPIPE when we get EPIPE upload-archive: use argv_array to store client arguments upload-archive: do not copy repo name send-pack: prefer prefixcmp over memcmp in receive_status fetch-pack: fix out-of-bounds buffer offset in get_ack upload-pack: remove packet debugging harness upload-pack: do not add duplicate objects to shallow list upload-pack: use get_sha1_hex to parse "shallow" lines
