We've been seeing crashes in libbfd when we attempt to generate a stack trace from multiple threads. It turns out that libbfd is NOT thread-safe. It can cache the bfd structure and give it to multiple threads without protecting itself. To get around this, we've added a global mutex around the bfd functions and also have refactored the use of those functions to be more efficient and to provide more information about inlined functions. Also added a few more tests to test_pbx.c. One just calls ast_assert() and the other calls ast_log_backtrace(). Neither are run by default. WARNING: This change necessitated changing the return value of ast_bt_get_symbols() from an array of strings to a VECTOR of strings. However, the use of this function outside Asterisk is not likely.

From 16.0.0 to 16.1.0:
|
|
|
|
Core:
|
|
- ast_bt_get_symbols() now returns a vector of strings instead of an
|
|
array of strings. This must be freed with ast_bt_free_symbols.
|
|
|
|
New in 16.0.0:
|
|
|
|
app_fax:
|
|
- The app_fax module is now deprecated, users should migrate to the
|
|
replacement module res_fax.
|
|
|
|
app_macro:
|
|
- The app_macro module is now deprecated and by default it is no longer
|
|
built. Users should migrate to app_stack (Gosub). A warning is logged
|
|
the first time any Macro is used.
|
|
|
|
AMI:
|
|
- The ContactStatus and Status fields for the manager events ContactStatus
|
|
and ContactStatusDetail are now set to "NonQualified" when a contact exists
|
|
but has not been qualified.
|
|
- The ContactStatus event will no longer be sent by PJSIP when a device
|
|
refreshes its registration.
|
|
- The "Newexten" event is now part of the "dialplan" class. The documentation
|
|
for Asterisk 15 already specified this, but the implementation was actually
|
|
using the "call" class instead.
|
|
|
|
ARI:
|
|
- The ContactInfo event's contact_status field is now set to "NonQualified"
|
|
when a contact exists but has not been qualified.
|
|
|
|
Build System:
|
|
- MALLOC_DEBUG no longer has an effect on Asterisk's ABI. Asterisk built
|
|
with MALLOC_DEBUG can now successfully load binary modules built without
|
|
MALLOC_DEBUG and vice versa. Third-party pre-compiled modules no longer
|
|
need to have a special build with it enabled.
|
|
|
|
- Asterisk now depends on libjansson >= 2.11. If this version is not
|
|
available on your distro you can use `./configure --with-jansson-bundled`.
|
|
|
|
chan_dahdi:
|
|
- Timeouts for reading digits from analog phones are now configurable in
|
|
chan_dahdi.conf: firstdigit_timeout, interdigit_timeout, matchdigit_timeout.
|
|
|
|
cdr_syslog:
|
|
- The cdr_syslog module is now deprecated and by default it is no longer
|
|
built.
|
|
|
|
res_config_sqlite:
|
|
- The res_config_sqlite module is now deprecated, users should migrate to the
|
|
replacement module res_config_sqlite3.
|
|
|
|
res_monitor:
|
|
- The res_monitor module is now deprecated, users should migrate to the
|
|
replacement module app_mixmonitor.
|
|
|
|
Core:
|
|
- libedit is no longer available as an embedded library and must be provided
|
|
by the system.
|
|
- The module loader now enforces inter-module dependencies. This ensures that
|
|
a module is not started before another it depends on, even if preload is used.
|
|
If a dependency is not available or fails to startup this will block any
|
|
dependants from startup.
|
|
- Parts of the Asterisk core which can load configuration from realtime are now
|
|
built-in modules. It is no longer necessary to preload realtime drivers as
|
|
they are always initialized before the built-in modules.
