Hello!
I am using channels to talk to an HTTP server running on localhost:
let channel = ch_open('localhost:1234', {'mode': 'raw'}
let str = '...' " <- this is raw HTTP
let response = ch_evalraw(channel, str)
The HTTP response's body is a JSON string.
I find intermittently (say 50%-70% of the time) the JSON in the response is
truncated. It is alway truncated in the same spot, which is after ~4300 bytes.
The weird thing is that when I log channel activity with `call
ch_logfile('channelog', 'w')` the response is never truncated.
In the channel log I can see the successful response being received in two
parts, with the first part corresponding to what I get "in full" when the
response is truncated. Here's an excerpt:
2.284366 on 8: Created channel
2.285209 on 8: Connecting to localhost port 1234
2.285309 on 8: Waiting for connection (waiting 1 msec)...
2.285449 on 8: Connection made
2.285731 SEND on 8: 'POST /path/to/endpoint HTTP/1.0
Host: localhost
Content-Type: application/x-www-form-urlencoded
Content-Length: 120
{"some json that":"i am sending"}'
2.285779 on 8: Blocking RAW read, timeout: 2000 msec
2.285793 on 8: Waiting for up to 2000 msec
2.286701 RECV on 8: 'HTTP/1.0 200 OK^M
Content-Type: application/json^M
Date: Wed, 25 Oct 2017 11:02:55 GMT^M
^M
{"first part of response":"json truncated here
2.286753 RECV on 8: 'and it continues on to the end}'
2.286775 on 8: Returning 6320 bytes
2.287753 on 8: channel_select_check(): Read EOF from ch_part[0], closing
2.291400 : looking for messages on channels
2.291412 on 8: Closing channel because all readable fds are closed
2.291420 on 8: Closing channel
2.291427 on 8: Closing channel
2.291433 on 8: Clearing channel
2.291441 on 8: Freeing channel
It seems that channel logging somehow forces `ch_evalraw()` to stitch together
all received parts into a single response. And that without channel logging,
50%-70% of the time only the part received first is returned by `ch_evalraw()`.
How can I get `ch_evalraw()` to give me everything it receives without having
to log the channel's activity?
Many thanks in advance!
Yours,
Andrew Stewart
