VERY BIG TODO:
|
|
- right now i will use long polling ajax calls when feedback from to the client
|
|
is needed. In the long term this should be changed to websockets (ws). But
|
|
right now ws specification is not final anyway. :)
|
|
|
|
- handle errors after all system call...especially open, close, etc.
|
|
|
|
- IPV6 support
|
|
|
|
- There seem to be a problem in the server under heavy load. Some tests with ab show that at some point it does not accept any more connections. Nor does it seem to answer request. I guess that it might be difficult to find this....
|
|
=> might be done... maybe not completely, I still loose connections under very high load.
|
|
|
|
- using tsearch for my memory management was kind of a bad idea. tsearch uses malloc and free upon addition and remove of elements. Resulting again in uncontroolled heap usage. I guess I have to implement my own tree mechanism here, which does not involve further allocation.
|
|
|
|
- another bug: if there is trailing garbage on the header line
|
|
we got a segfault...
|
|
|
|
GET /images/waldschrat.jpg HTTP/1.1^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D^[[D
|
|
^[[D = backspace...
|
|
|
|
- the unexpected connection close seems to occur just on concurrency over
|
|
1000 paralell connections...maybe this gives a hint.
|
|
|
|
- after changing to non blocking sockets the server hangs after some requests.
|
|
have to check when this happens....
|
|
* it seems that it does not occur without keep-alive and concurrency
|
|
* also concurrent connection don't seem to make a problem.
|
|
* keep-alive alone again don't seem to be a problem...
|
|
!!!! if both are active something is screwed up.... !!!!
