Here is the caller graph for this function:

◆ metaserver2_init()

int metaserver2_init ( void )

This initializes the metaserver2 logic - it reads the metaserver2 file, storing the values away. Note that it may be possible/desirable for the server to re-read the values and restart connections (for example, a new metaserver has been added and you want to start updates to it immediately and not restart the server). Because of that, there is some extra logic (has_init) to try to take that into account.

Returns: 1 if we will be updating the metaserver, 0 if no metaserver updates

Here is the caller graph for this function:

◆ metaserver2_thread()

void metaserver2_thread ( )

Repeatedly send updates to the metaserver, stopping when ms2_signal is acquired. Works in the background.

◆ metaserver2_updates()

static void metaserver2_updates ( void )

static

This sends an update to the various metaservers. It generates the form, and then sends it to the server

◆ metaserver2_writer()

static size_t metaserver2_writer	(	void *	ptr,
		size_t	size,
		size_t	nmemb,
		void *	data
	)

static

Handles writing of HTTP request data from the metaserver2. We treat the data as a string. We should really pay attention to the header data, and do something clever if we get 404 codes or the like.

Parameters

ptr	actual data.
size	size of the data.
nmemb	number of elements.
data	user-provided data, unused.

Returns: number of bytes processed, always the full size.

Here is the caller graph for this function:

◆ metaserver_update()

void metaserver_update ( void )

Updates our info in the metaserver Note that this is used for both metaserver1 and metaserver2 - for metaserver2, it just copies dynamic data into private data structure, doing locking in the process.
