bbb245654d Pass the base for strtoll() to kore_strtonum(), breakage ensues if we depend on the "auto" detection that happens when we pass 0 to strtoll() as base. 2013-08-13 16:13:43 +02:00
Joris Vink
3075162855 Add http_argument_urldecode() which takes a string and decodes any url encoding done to it. 
Change kore_strtonum() to pass 0 to strtoll by default so we can use it to convert hex numbers (prepended with 0x) as well.

db7ed69f2a Add kore_buf_replace_string(). 
kore_buf_replace_string allows you to replace occurances of a certain
string with something else.

Example:
	char	*username = "Joris";

	page = kore_buf_create(static_len_html_profile);
	kore_buf_append(page, static_html_profile, static_len_html_profile);
	kore_buf_replace_string(page, "%name%", username, strlen(username));

ef814a677d Add http_argument_multiple_lookup() and http_argument_multiple_free(). 
Prototypes:
	int	http_argument_multiple_lookup(struct http_req *req,
		    struct http_arg *args);
	void	http_argument_multiple_free(struct http_arg *args);

These functions can be used to lookup arguments in a single call.

args points to an array of struct http_arg elements. Each of them
have the argument name set and its value set to NULL.

The array must have its last element name field set to NULL.

Upon return http_argument_multiple_lookup() gives the caller the
number of arguments that were successfully found. It makes their values
available under the value field in the struct http_arg array passed.

Example:
	int			v;
	struct http_args	args[4];

	memset(args, 0, sizeof(args));
	args[0].name = "email";
	args[1].name = "password1";
	args[2].name = "password2";
	args[3].name = NULL;

	v = http_argument_multiple_lookup(req, args);
	if (v != 3) {
		kore_debug("argument %s was not present", args[v].name);
	} else {
		for (v = 0; args[v].name != NULL; v++)
			kore_debug("%s -> %s", args[v].name, args[v].value);
	}

	http_argument_multiple_free(args);

36d603ea67 When negotiating the protocol to be used using the NPN extension keep in mind that http/1.1 can be given there as well. (Googlebot does this, and thus couldn't access Kore sites). 
On top of that be extra careful with how many bytes we memcmp() if we receive data from the NPN extension.

This fix makes googlebot and anybody negotiating http/1.1 over NPN properly.

95bacb5690 Kore will now keep track of page handlers that cause workers to die. 
This is useful to track down any issues you might have in your module.

A log entry with a page handler causing issues looks like:

Jul  7 14:44:30 devbook kore[18191]: [parent]: worker 1 (pid: 18193) (hdlr: 0x242d9c0) gone

4b2420097b - Better spread load between all worker processes. 
- Introduce own memory management system on top of malloc to keep track
  of all our allocations and free's. Later we should introduce a pooling
  mechanism for fixed size allocations (http_request comes to mind).
- Introduce ssl_cipher in configuration.

Memory usage is kind of high right now, but it seems its OpenSSL
doing it rather then Kore.

2fc5233358 Rework the way worker processes give each other the accept lock. 
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.

Joris Vink
0dda6f996f Add a form of synchronization between what worker will be accepting 
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.

dynamic /	serve_other

/ will be matched to serve_index, while /foo will be matched to serve_foo and /bar will be matched to serve_other for example.

http_populate_arguments() before using http_argument_lookup() to lookup a given argument.

population uses the appropriate query string (from GET or POST) automatically.

a9ebf37cae allow modules to add headers to the response before calling http_response() 
by calling http_response_header_add().

fix wrong overflow check in spdy_stream_get_header().

html_inject now exports last modified timestamp for the files that are
compiled into the module in the format static_mtime_<type>_<name>.

modules can now look into the request headers using http_request_header_get().

a074258dcc rework the way events trigger and the way we handle them. follow the manual for once, as edge trigger does not refire until we got an EAGAIN. 
introduce net_send_flush() and net_recv_flush() for this purpose, we attempt to make as much headway as possible until we reach EAGAIN or until we can simply pickup again later.

should merge all the stuff in http_response() into a single send buffer, **out is in place in net_send_queue() for that purpose.
