Allows you to configure maximum amount of seconds an HTTP connection
can stay open (does not affect SPDY connections). If set to 0 it will
disable keep-alive all together.
Add some inttypes fluff.
If enabled Kore adds the HSTS header to every response.
- Additionally, fix some typos in the example configuration.
- Change default SSL cipher list again, no more RC4 and almost PFS for all browsers.
- http_header_max:
Maximum size of HTTP headers (in non SPDY connections).
- http_postbody_max:
Maximum size of an HTTP POST body (both in SPDY and HTTP mode).
Right now Kore will simply DC the client, ideally we want to send
a 413 (entity too large) to the client however.
See modules/examples/module.conf for more.
New API functions (docs need to be updated):
- http_file_lookup()
- http_file_add()
- http_argument_add()
- kore_strip_chars()
- kore_mem_find()
- Add an example under the example module on how files can be read.
- Keep HTTP requests in connection, so we can delete them if the connection
ends before the requests do (this way we don't leak them).
- When spdy_stream_close() is called, delete the attached http request.
(This shouldn't hurt to do, so hopefully won't cause major fallout).
- When parsing HTTP, find the first occurence of end-of-headers so uploads
with multipart/form-data can succeed properly.
- Add a test upload page to the example module.
Instead of waiting until one worker is filled up on connections
the workers find the next lowest loaded worker and will hand
over the lock to them instead. This will cause a nicer spread of load.
Instead of running one accept per event loop, we attempt to accept
as many as worker_max_connections allows.
Refactor net sending/recv code a bit.
new connections and which ones will not be notified for it.
Fixes the thundering herd problem, and nicely spreads out load between
all the workers equally. A configuration option (workers_max_connections)
is available to tweak how many connections a worker will have before
giving up the accept lock.
Two ways are added to this commit for access locking:
- Locking via semaphores.
- Locking via GCC's builtin atomic methods.
The default is running with semaphores disabled (OpenBSD cannot do
sem_init() with pshared set to 1, which is required).
If you want to use semaphores add KORE_USE_SEMAPHORES to CFLAGS,
and -lpthread to LDFLAGS in the Makefile.
Other fixes:
- BSD: add a timeout to kevent().
- Merge kore_worker_wait together, linux knows waitpid() as well.
- Send the correct SIGQUIT signal to workers instead of SIGINT.
- Fix kore_time_ms().
- Log fatal worker messages in syslog.
- Refactor code even more.
- Do not free our own kore_worker structure.
