2018-10-23Remove the global variable for connectionOndrej Fabry2-52/+20
- this also fixes issue where after connect failure all following connects failed 'with only one connection per process is supported' - this global was used to limit to single connection, but the actual limitation is for the adapter and with different adapter implementation multiple connections could actually be supported - the global defined in the vppapiclient package will continue to limit to single connection via VppClient implementation of the adapter Change-Id: Id06dd6e80b51d1d43f6f75bbcc6e01c6f21c605a Signed-off-by: Ondrej Fabry <ofabry@cisco.com>

2018-06-27mock adapter: Group all replies for one request under one call to MockReplyMilan Lenco1-27/+67
Sequence numbers are now used to match requests with replies. Mock adapter thus has to be able to tell how many messages from the head of the queue with mock replies belong to the currently processed request. Then they can be given the right context and the rest of the queued replies are postponed to be delivered later (when context of their request is known). All replies for one request are now therefore queued together. This affects just multipart requests for which replies have to be pushed all at once. The trailling control ping reply is still queued separately, however, because that is actualy another request, e.g.: mockVpp.MockReply( // push multipart messages all at once &interfaces.SwInterfaceDetails{SwIfIndex:1}, &interfaces.SwInterfaceDetails{SwIfIndex:2}, &interfaces.SwInterfaceDetails{SwIfIndex:3}, ) mockVpp.MockReply(&vpe.ControlPingReply{}) Even if the multipart request has no replies, MockReply has to be called exactly twice: mockVpp.MockReply() // zero multipart messages mockVpp.MockReply(&vpe.ControlPingReply{}) Change-Id: I28c15d2f52d14dca0b7fb06033d7270a7da2bde6 Signed-off-by: Milan Lenco <milan.lenco@pantheon.tech>
2018-06-26Pair requests with replies using sequence numbersMilan Lenco3-60/+304
Requests are given sequence numbers (cycling over a finite set of 2^16 integers) that are stored into the lower 16bits of the context. 1bit is also allocated for isMultipart boolean flag and the remaining 15bits are used to store the channel ID. The sequence numbers allow to reliably pair replies with requests, even in scenarious with timeouted requests or ignored (unread) replies. Sequencing is not used with asynchronous messaging as it is implemented by methods of the Channel structure, i.e. above ReqChan and ReplyChan channels.
