Can somebody check have I missed any lang?
* There is an suspicious hardcoded T_CALL in the cpp-generator, line 2759
* Same in the t_c_glib generator at line 1528
* thrift-protocol-spec.md lacks T_ONEWAY in line 46
* PeekProcessor.cpp line 69
* StatsProcessor.h line 53
* not sure what to do with AllProtocolTests.tcc
I take care about these:
* all generators using TMessageType
* including AS3, Go, Delphi, C#, Java, JavaME, Lua, Perl ... and Haxe^W^W

Pushed fix for Compact protocol, moving to Dense :)

got it:
is:
messageType = (TMessageType)((versionAndType >> TYPE_SHIFT_AMOUNT) &
0x03);
should be:
messageType = (TMessageType)((versionAndType >> TYPE_SHIFT_AMOUNT) &
0x07);
as TYPE_MASK = 0xE0 // 1110 0000 - 3bits, 0x03 - 2bits
I'll commit it as soon as I check all other impl of compact protocol

I was able to reproduce Steven's problem. Seems that T_ONEWAY encodes
badly in Compact protocol: "Thrift: Tue Sep 16 11:54:30 2014 received
invalid message type 0 from client"
I'll debug all those shifts and masks etc, hopefully it's a programming
mistake, not protocol issue (T_ONEWAY == 4 and there are 4 bits for
message type, so everything should be ok...)

Looks like an oversight to me. The server side of the generated code in
C++ respects T_ONEWAY and T_CALL.
Coincidentally, someone at my company was likely going to run into this
issue in about three weeks. They are doing some fancy pass-through
server
stuff, and as a 'server' without access to a specific .thrift file, they
need to know whether to wait as a 'client' when passing an RPC. They
were
planning on looking at the message type to figure that out.
I've looked at your commit, but have not tested it. +0.9.

I suspected that something will break - that's why I submited pull
req to see what will Travis say :)
I'll look further into it, also I hope for some explaining comments
to issue from devs ;)

Hello Konrad,
I looked at the patch but it only resolves the issue posted; and may
lead
to deeper problems:
Whereas TBinaryProtocol is ok with T_ONEWAY flag, TCompactProtocol
seems
to have a different way of handling things [it filters it out?], and
TDenseProtocol also failed test but I didn't follow up with that and
the
rest of the provided protocols.

I can confirm that for my oneway messages I observe the same T_CALL
(I
have
not looked into why)
The difference is that one way messages have fooClient::bar that
just
call
send_bar and if it was not oneway it would call send_bar AND
recv_bar
Now realize that you do not have to use the RPC mechanism at all -
you
could just serialize objects into your messages, perhaps with a
custom
header (there may be something supported already). This is what we
have
been doing since thrift0.6.x for SOME of our connections - for that
case
we
do not even define a service, just objects and an enumeration of
messages

Hi,
the following service generates oneway RPC call flagged with T_CALL

between request - reply patterns and push - pull ones at socket

Am I doing something wrong ?
