2006-11-26- Add some comments on thread storage with a brief explanation of what it isRussell Bryant
as well as what the motivation is for using it. - Add a comment by the declaration of ast_inet_ntoa() noting that this function is not reentrant, and the result of a previous call to the function is no longer valid after calling it again. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@48019 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2006-08-08Merge team/russell/ast_verbose_threadstorageRussell Bryant
- instead of defining a free() wrapper in a bunch of files, define it as ast_free() in utils.h and remove the copies from all the files. - centralize and abstract the code used for doing thread storage. The code lives in threadstorage.h, with one function being implemented in utils.c. This new API includes generic thread storage as well as special functions for handling thread local dynamic length string buffers. - update ast_inet_ntoa() to use the new threadstorage API - update ast_state2str() to use the new threadstorage API - update ast_cli() to use the new threadstorage API - Modify manager_event() to use thread storage. Instead of using a buffer of 4096 characters as the workspace for building the manager event, use a thread local dynamic string. Now there is no length limitation on the length of the body of a manager event. - Significantly simplify the handling of ast_verbose() ... - Instead of using a static char buffer and a lock to make sure only one thread can be using ast_verbose() at a time, use a thread local dynamic string as the workspace for preparing the verbose message. Instead of locking around the entire function, the only locking done now is when the message has been built and is being deliviered to the list of registered verbose message handlers. - This function was doing a strdup() on every message passed to it and keeping a queue of the last 200 messages in memory. This has been completely removed. The only place this was used was that if there were any messages in the verbose queue when a verbose handler was registered, all of the messages in the queue would be fed to it. So, I just made sure that the console verbose handler and the network verbose handler (for remote asterisk consoles) were registered before any verbose messages. pbx_gtkconsole and pbx_kdeconsole will now lose a few verbose messages at startup, but I didn't feel the performance hit of this message queue was worth saving the initial verbose output for these very rarely used modules. - I have removed the last three arguments to the verbose handlers, leaving only the string itself because they aren't needed anymore. For example, ast_verbose had some logic for telling the verbose handler to add a newline if the buffer was completely full. Now that the buffer can grow as needed, this doesn't matter anymore. - remove unused function, ast_verbose_dmesg() which was to dispatch the message queue - Convert the list of verbose handlers to use the linked list macros. - add missing newline characters to a few ast_verbose() calls - convert the list of log channels to use the linked list macros in logger.c - fix close_logger() to close all of the files it opened for logging - update ast_log() to use a thread local dynamic string for its workspace for preparing log messages instead of a buffer of size BUFSIZ (8kB on my system) allocated on the stack. The dynamic string in this case is limited to only growing to a maximum size of BUFSIZ. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@39272 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2006-04-12add 'show threads' and 'show profile' commands.Luigi Rizzo
These are momstly debugging tools for developers, a bit documented in the header files (utils.h), although more documentation is definitely necessary. The performance impact is close to zero(*) so there is no need to compile it conditionally. (*) not completely true - thread destruction still needs to search a list _but_ this can be easily optimized if we end up with hundreds of active threads (in which case, though, the problem is clearly elsewhere). git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@19544 65c4cc65-6c06-0410-ace0-fbb531ad65f3

Anywhere that we check for a successful allocation after a call to ast_strdupa is unnecessary and should be removed. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@8356 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2006-01-13Various cleanups from comments in an email from Luigi Rizzo. Thank you!Russell Bryant
- Use a cleaner syntax for declaring the allocation macros - Fix return value for ast_strdup/ast_strndup - remove safe_strdup from app_macro, since ast_strup does the same thing - fix a place in app_queue where ast_calloc+strncpy was used instead of ast_strdup. If you are helping out with these conversions, please watch out for other places where this is done. - add a note to the coding guidelines about the fix to app_queue git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@8065 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2006-01-10Add wrappers for commonly used memory allocation functions. These wrappersRussell Bryant
add an automatically generated Asterisk log message if the allocation fails for some reason. Otherwise, they are functionally the same, with the exception of ast_strdup and ast_strndup. These functions have the added ability to accept a NULL argument without error, which will just be ignored without generating an error. The coding guidelines have also been updated to reflect all of this information. (issue #4996) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@7952 65c4cc65-6c06-0410-ace0-fbb531ad65f3
