Changelog

All changes to this project will be documented in this file.

[7.8.2] - 2019-12-25

(ws cobra to sentry) bound the queue size used to hold up cobra messages before they are sent to sentry. Default queue size is a 100 messages. Without such limit the program runs out of memory when a subscriber receive a lot of messages that cannot make it to sentry

[7.8.1] - 2019-12-25

(ws client) use correct compilation defines so that spdlog is not used as a header only library (reduce binary size and increase compilation speed)

[7.8.0] - 2019-12-24

(ws client) all commands use spdlog instead of std::cerr or std::cout for logging

[7.6.5] - 2019-12-24

(cobra client) send a websocket ping every 30s to keep the connection opened

[7.6.4] - 2019-12-22

(client) error handling, quote url in error case when failing to parse one (ws) ws_cobra_publish: register callbacks before connecting (doc) mention mbedtls in supported ssl server backend

[7.6.3] - 2019-12-20

(tls) add a simple description of the TLS configuration routine for debugging

[7.6.2] - 2019-12-20

(mbedtls) correct support for using own certificate and private key

[7.6.1] - 2019-12-20

[7.5.6] - 2019-12-18

(tls servers) Make it clear that apple ssl and mbedtls backends do not support SSL in server mode

[7.5.5] - 2019-12-17

(tls options client) TLSOptions struct _validated member should be initialized to false

[7.5.4] - 2019-12-16

(websocket client) improve the error message when connecting to a non websocket server

Before:

Connection error: Got bad status connecting to example.com:443, status: 200, HTTP Status line: HTTP/1.1 200 OK

After:

Connection error: Expecting status 101 (Switching Protocol), got 200 status connecting to example.com:443, HTTP Status line: HTTP/1.1 200 OK

[7.5.3] - 2019-12-12

(server) attempt at fixing #131 by using blocking writes in server mode

[7.5.2] - 2019-12-11

(ws) cobra to sentry - created events with sentry tags based on tags present in the cobra messages

[7.5.1] - 2019-12-06

(mac) convert SSL errors to utf8

[7.5.0] - 2019-12-05

• (ws) cobra to sentry. Handle Error 429 Too Many Requests and politely wait before sending more data to sentry.

In the example below sentry we are sending data too fast, sentry asks us to slow down which we do. Notice how the sent count stop increasing, while we are waiting for 41 seconds.

[5.2.0] - 2019-09-04

• Fragmentation: for sent messages which are compressed, the continuation fragments should not have the rsv1 bit set (fix all autobahn tests for zlib compression 12.X)
