Subject: [PATCH v2 00/11] Advertise trace2 SID in protocol capabilities
Date: Mon,  2 Nov 2020 14:30:58 -0800	[thread overview]
Message-ID: <cover.1604355792.git.steadmon@google.com> (raw)
In-Reply-To: <cover.1604006121.git.steadmon@google.com>

In order to more easily debug remote operations, it is useful to be able
to inspect both client-side and server-side traces. This series allows
clients to record the server's trace2 session ID, and vice versa, by
advertising the SID in a new "trace2-sid" protocol capability.

Changes since V1:
* Added a public trace2_session_id() function to trace2.{h,c}. Used this
  in place of tr2_sid_get().
* Fixed a style issue regarding using NULL rather than 0.

Josh Steadmon (11):
  docs: new capability to advertise trace2 SIDs
  docs: new trace2.advertiseSID option
  trace2: add a public function for getting the SID
  upload-pack: advertise trace2 SID in v0 capabilities
  receive-pack: advertise trace2 SID in v0 capabilities
  serve: advertise trace2 SID in v2 capabilities
  transport: log received server trace2 SID
  fetch-pack: advertise trace2 SID in capabilities
  upload-pack, serve: log received client trace2 SID
  send-pack: advertise trace2 SID in capabilities
  receive-pack: log received client trace2 SID
