I'm hoping to get some more in depth review before I do any more re-rolls, but for those interested I will need to do a re-roll to eliminate the prelude from the http transport. This is the prelude which includes the service line followed by any number of packet lines culminating in a flush-pkt like so: # service=git-upload-pack some other optional lines 0000 With this eliminated all transports will be exactly the same, the only difference will be how the protocol is tunneled. > > Brandon Williams (35): > pkt-line: introduce packet_read_with_status > pkt-line: introduce struct packet_reader > pkt-line: add delim packet support > upload-pack: convert to a builtin > upload-pack: factor out processing lines > transport: use get_refs_via_connect to get refs > connect: convert get_remote_heads to use struct packet_reader > connect: discover protocol version outside of get_remote_heads > transport: store protocol version > protocol: introduce enum protocol_version value protocol_v2 > test-pkt-line: introduce a packet-line test helper > serve: introduce git-serve > ls-refs: introduce ls-refs server command > connect: request remote refs using v2 > transport: convert get_refs_list to take a list of ref patterns > transport: convert transport_get_remote_refs to take a list of ref > patterns > ls-remote: pass ref patterns when requesting a remote's refs > fetch: pass ref patterns when fetching > push: pass ref patterns when pushing > upload-pack: introduce fetch server command > fetch-pack: perform a fetch using v2 > upload-pack: support shallow requests > fetch-pack: support shallow requests > connect: refactor git_connect to only get the protocol version once > connect: don't request v2 when pushing > transport-helper: remove name parameter > transport-helper: refactor process_connect_service > transport-helper: introduce stateless-connect > pkt-line: add packet_buf_write_len function > remote-curl: create copy of the service name > remote-curl: store the protocol version the server responded with > http: allow providing extra headers for http requests > http: don't always add Git-Protocol header > remote-curl: implement stateless-connect command > remote-curl: don't request v2 when pushing > > .gitignore | 1 + > Documentation/technical/protocol-v2.txt | 338 +++++++++++++++++ > Makefile | 7 +- > builtin.h | 2 + > builtin/clone.c | 2 +- > builtin/fetch-pack.c | 21 +- > builtin/fetch.c | 14 +- > builtin/ls-remote.c | 7 +- > builtin/receive-pack.c | 6 + > builtin/remote.c | 2 +- > builtin/send-pack.c | 20 +- > builtin/serve.c | 30 ++ > builtin/upload-pack.c | 74 ++++ > connect.c | 352 +++++++++++++----- > connect.h | 7 + > fetch-pack.c | 319 +++++++++++++++- > fetch-pack.h | 4 +- > git.c | 2 + > http.c | 25 +- > http.h | 2 + > ls-refs.c | 96 +++++ > ls-refs.h | 9 + > pkt-line.c | 149 +++++++- > pkt-line.h | 77 ++++ > protocol.c | 2 + > protocol.h | 1 + > remote-curl.c | 257 ++++++++++++- > remote.h | 9 +- > serve.c | 260 +++++++++++++ > serve.h | 15 + > t/helper/test-pkt-line.c | 64 ++++ > t/t5701-git-serve.sh | 176 +++++++++ > t/t5702-protocol-v2.sh | 239 ++++++++++++ > transport-helper.c | 84 +++-- > transport-internal.h | 4 +- > transport.c | 116 ++++-- > transport.h | 9 +- > upload-pack.c | 625 ++++++++++++++++++++++++-------- > upload-pack.h | 21 ++ > 39 files changed, 3088 insertions(+), 360 deletions(-) > create mode 100644 Documentation/technical/protocol-v2.txt > create mode 100644 builtin/serve.c > create mode 100644 builtin/upload-pack.c > create mode 100644 ls-refs.c > create mode 100644 ls-refs.h > create mode 100644 serve.c > create mode 100644 serve.h > create mode 100644 t/helper/test-pkt-line.c > create mode 100755 t/t5701-git-serve.sh > create mode 100755 t/t5702-protocol-v2.sh > create mode 100644 upload-pack.h > > -- > 2.16.0.rc1.238.g530d649a79-goog > -- Brandon Williams
