Matthew Jordan 9057aa20b6 Backed out core changes from r346391
During testing, it was discovered that there were a number of side effects
introduced by r346391 and subsequent check-ins related to it (r346429,
r346617, and r346655).  This included the /main/stdtime/ test 'hanging',
as well as the remote console option failing to receive the appropriate output
after a period of time.

I only backed out the changes to main/ and utils/, as this was adequate
to reverse the behavior experienced.

    Fix deadlock when using dummy channels.
    
    Dummy channels created by ast_dummy_channel_alloc() should be destoyed by
    ast_channel_unref().  Using ast_channel_release() needlessly grabs the
    channel container lock and can cause a deadlock as a result.
    
    * Analyzed use of ast_dummy_channel_alloc() and made use
    ast_channel_unref() when done with the dummy channel.  (Primary reason for
    the reported deadlock.)
    
    * Made app_dial.c:dial_exec_full() not call ast_call() holding any channel
    locks.  Chan_local could not perform deadlock avoidance correctly.
    (Potential deadlock exposed by this issue.  Secondary reason for the
    reported deadlock since the held lock was part of the deadlock chain.)
    
    * Fixed some uses of ast_dummy_channel_alloc() not checking the returned
    channel pointer for failure.
    
    * Fixed some potential chan=NULL pointer usage in func_odbc.c.  Protected
    by testing the bogus_chan value.
    
    * Fixed needlessly clearing a 1024 char auto array when setting the first
    char to zero is enough in manager.c:action_getvar().

    Fix crash with res_fax when MALLOC_DEBUG and "core stop gracefully" are used.
    
    Asterisk crashes if MALLOC_DEBUG is enabled when res_fax tries to
    unregister its logger level.
    
    * Make ast_logger_unregister_level() use ast_free() instead of free().
    When MALLOC_DEBUG is enabled, ast_free() does not degenerate into a call
    to free().  Therefore, if you allocated memory with a form of ast_malloc
    you must free it with ast_free.

    Logger does not warn of failure to open logging channels
    
    Currently, logger only prints an error message to stderr when it fails to open
    a logger channel where many users will not see it because the logger lock is
    held.  The alternative provided by this patch is to log the error to all
    attached consoles in the hopes that it will be easier to see.  Additionally,
    this patch prevents the failed logger channel from being added to the list
    where it would silently fail on each call to the Asterisk logger.

    Output of queue log not started until logger reloaded.
    
    ASTERISK-15863 caused a regression with queue logging.  The output of the
    queue log is not started until the logger configuration is reloaded.
    
    * Queue log initialization is completely delayed until the first message
    is posted to the queue log system.  Including the initial opening of the
    queue log file.
    
    * Fixed rotate_file() ROTATE strategy to give the file just rotated out to
    the configured exec function after rotate.  Just like the other strategies.
    
    * Fixed logger reload to always post the queue reload entry instead of
    just if there is a queue log file.
    
    * Refactored some code to eliminate some redundancy and to reduce stack
    utilization.

  Use sigaction for signals which should persist past the initial trigger, not signal.
  
  If you call signal() in a Solaris signal handler, instead of just resetting
  the signal handler, it causes the signal to refire, because the signal is not
  marked as handled prior to the signal handler being called.  This effectively
  causes Solaris to immediately exceed the threadstack in recursive signal
  handlers and crash.

Kevin P. Fleming e77efbc12e Add ability for logger channels to include *all* levels.
Now that Asterisk modules can dynamically create and destroy logger levels
on demand, it's useful to be able to configure a logger channel (console,
file, whatever) to be able to accept log messages from *all* levels, even
levels created dynamically. This patch adds support for this, by allowing
the '*' level name to be used in logger.conf.

Russell Bryant 0264eef115 Merge the new Channel Event Logging (CEL) subsystem.
CEL is the new system for logging channel events.  This was inspired after
facing many problems trying to represent what is possible to happen to a call
in Asterisk using CDR records.  For more information on CEL, see the built in
HTML or PDF documentation generated from the files in doc/tex/.

Many thanks to Steve Murphy (murf) and Brian Degenhardt (bmd) for their hard
work developing this code.  Also, thanks to Matt Nicholson (mnicholson) and
Sean Bright (seanbright) for their assistance in the final push to get this
code ready for Asterisk trunk.

Joshua Colp ea89db8ce0 Fix an incorrect call to ast_string_field_free_memory which caused a crash in the logger.
Since the message structure is allocated using ast_calloc_with_stringfields we do not need to
free the memory used for the stringfields as it will get freed when the message structure is.

Kevin P. Fleming d1e0b11343 Add ability for modules to dynamically register logger levels
This patch adds the ability for modules to dynamically create logger levels for their own use; these are named levels just like the built-in levels, and can be directed to any destination that the logger can send any level to, by including their names in logger.conf.

Tilghman Lesher c524f905a6 Two fixes found while debugging with ast_backtrace():
1) If MALLOC_DEBUG is used when concurrently using ast_backtrace, the free()
used in that routine will trigger an error, because the memory was allocated
internally to libc, where we could not intercept that call to wrap it.
Therefore, it's not memory we knew about, and the free is reported as an
error.

2) Now that channels are objects, the old hack of initializing a channel
to all zeroes no longer works, since we may try to call something like
ast_channel_lock() within a function on that reference.  In that case, it's
reported as an error, because the pointer isn't an object reference.

  Make absolute paths for logger channels work properly
  
  (Note: This is not a new feature, it was previously undocumented and broken.)
  
  The Asterisk logger has a feature to support absolute pathnames for logger channels, but the code implementing the feature was broken. This has been fixed, and the absolute path feature is now documented in the sample logger.conf.

Kevin P. Fleming a3af213506 Remove rarely-used event_log/LOG_EVENT support
In discussions today at the Europe Asterisk Developer Meet-Up, we determined that
the event_log was used in only 9 places in the entire tree, and really was not needed
at all. The users have been converted to use LOG_NOTICE, or the messages have been
removed since other messages were already in place that provided the same information.

Kevin P. Fleming b8b4d01b06 Fix an error in queue_log file rotation optimization code
This code was copy-and-pasted without properly changing references to event_rotate into queue_rotate, so under some conditions the log rotation would rotate queue_log even though it was not necessary.

Russell Bryant cba19c8a67 Convert the ast_channel data structure over to the astobj2 framework.
There is a lot that could be said about this, but the patch is a big 
improvement for performance, stability, code maintainability, 
and ease of future code development.

The channel list is no longer an unsorted linked list.  The main container 
for channels is an astobj2 hash table.  All of the code related to searching 
for channels or iterating active channels has been rewritten.  Let n be 
the number of active channels.  Iterating the channel list has gone from 
O(n^2) to O(n).  Searching for a channel by name went from O(n) to O(1).  
Searching for a channel by extension is still O(n), but uses a new method 
for doing so, which is more efficient.

The ast_channel object is now a reference counted object.  The benefits 
here are plentiful.  Some benefits directly related to issues in the 
previous code include:

1) When threads other than the channel thread owning a channel wanted 
   access to a channel, it had to hold the lock on it to ensure that it didn't 
   go away.  This is no longer a requirement.  Holding a reference is 
   sufficient.

2) There are places that now require less dealing with channel locks.

3) There are places where channel locks are held for much shorter periods 
   of time.

4) There are places where dealing with more than one channel at a time becomes 
   _MUCH_ easier.  ChanSpy is a great example of this.  Writing code in the 
   future that deals with multiple channels will be much easier.

Some additional information regarding channel locking and reference count 
handling can be found in channel.h, where a new section has been added that 
discusses some of the rules associated with it.

Mark Michelson also assisted with the development of this patch.  He did the 
conversion of ChanSpy and introduced a new API, ast_autochan, which makes it 
much easier to deal with holding on to a channel pointer for an extended period 
of time and having it get automatically updated if the channel gets masqueraded.
Mark was also a huge help in the code review process.

Thanks to David Vossel for his assistance with this branch, as well.  David 
did the conversion of the DAHDIScan application by making it become a wrapper 
for ChanSpy internally.

The changes come from the svn/asterisk/team/russell/ast_channel_ao2 branch.

Mark Michelson e32921415f Assist proper thread synchronization when stopping the logger thread.
I was finding that on my dev box, occasionally attempting to "stop now" in
trunk would cause Asterisk to hang. I traced this to the fact that the logger
thread was waiting on a condition which had already been signalled. The logger
thread also need to be sure to check the value of the close_logger_thread variable.

The close_logger_thread variable is only checked when the list of logmessages is empty.
This allows for the logger thread to print and free any pending messages before exiting.

update dev-mode compiler flags to match the ones used by default on Ubuntu Intrepid, so all developers will see the same warnings and errors

since this branch already had some printf format attributes, enable checking for them and tag functions that didn't have them

format attributes in a consistent way


------------------------------------------------------------------------

in addition:

move some format attributes from main/utils.c to the header files they belong in, and fix up references to the relevant functions based on new compiler warnings

Tilghman Lesher afb571ba8f Starting with a change to ensure that ast_verbose() preserves ABI compatibility
in 1.6.1 (as compared to 1.6.0 and versions of 1.4), this change also
deprecates the use of Asterisk with FreeBSD 4, given the central use of va_copy
in core functions.  va_copy() is C99, anyway, and we already require C99 for
other purposes, so this isn't really a big change anyway.  This change also
simplifies some of the core ast_str_* functions.
