Detailed Description
Typedef Documentation
◆ LocalMeta2Info
| typedef struct _LocalMeta2Info LocalMeta2Info |
LocalMeta2Info basically holds all the non server metaserver2 information that we read from the metaserver2 file. Could just have individual variables, but doing it as a structure is cleaner I think, and might be more flexible if in the future, we want to pass this information to other functions (like plugin or something)
◆ MetaServer2
| typedef struct _MetaServer2 MetaServer2 |
This is a linked list of all the metaservers - never really know how many we have.
Function Documentation
◆ free_metaserver2()
|
static |
This frees any data associated with the MetaServer2 info, including the pointer itself. Caller is responsible for updating pointers (ms->next) - really only used when wanting to free all data.
- Parameters
-
ms data to free, pointer becomes invalid.

◆ 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

◆ metaserver2_thread()
| void* metaserver2_thread | ( | void * | junk | ) |
metserver2_thread is the function called from pthread_create. it is a trivial function - it just sleeps and calls the update function. The sleep time here is really quite arbitrary, but once a minute is probably often enough. A better approach might be to do a time() call and see how long the update takes, and sleep according to that.
- Parameters
-
junk unused.
- Returns
- This function should never return/exit.

◆ metaserver2_writer()

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.

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.
