Crash when "data.sendQueue.len == 0" or "data.sendQueue.len - sendQueueBefore > 0"

assert == false stops my program when running in -d:dev. This happens almost randomly - sometimes on the first request, other times on 10th request when I refresh rapidly.

I am loading quite a few local files:

6 x CSS
8 x JS
5 x API calls which are initiated by 1 of the JS files with jQuery ajax as async

I have tried to disable the API calls, but no difference. My next step will be to strip out the files 1-by-1 and after that minimizing the size of the HTML page. Unless you can point me in another direction ;) ?

Errors

I am getting 2 different errors:

Solution

Compile options

compiling with --assertions:off or -d:release

Code

I can fix it by commenting out:

httpbeast/src/httpbeast.nim

Line 162 in 9820e05

assert data.sendQueue.len == 0

and

httpbeast/src/httpbeast.nim

Line 212 in 9820e05

assert data.sendQueue.len - sendQueueBefore > 0,

This is just a result of me being overly cautious. Many of these asserts no longer apply since I implemented pipelining support so I decided to simply remove them.
