Naveen Albert	393b903adc	cli: Prevent assertions on startup from bad ao2 refs. ... If "core show channels" is run before startup has completed, it is possible for bad ao2 refs to occur because the system is not yet fully initialized. This will lead to an assertion failing. To prevent this, initialization of CLI builtins is moved to be later along in the main load sequence. Core CLI commands are loaded at the same time, but channel-related commands are loaded later on.

Naveen Albert	12f693d401	cli: Fix CLI blocking forever on terminating backslash ... A corner case exists in CLI parsing where if a CLI user in a remote console ends with a backslash and then invokes command completion (using TAB or ?), then the console will freeze forever until a SIGQUIT signal is sent to the process, due to getting blocked forever reading the command completion. CTRL+C and other key combinations have no impact on the CLI session. This occurs because, in such cases, the CLI process is waiting for AST_CLI_COMPLETE_EOF to appear in the buffer from the main process, but instead the main process is confused by the funny syntax and thus prints out the CLI help. As a result, the CLI process is stuck on the read call, waiting for the completion that will never come. This prevents blocking forever by checking if the data from the main process starts with "Usage:". If it does, that means that CLI help was sent instead of the tab complete vector, and thus the CLI should bail out and not wait any longer.

Naveen Albert	467505d1da	asterisk.c: Warn of incompatibilities with remote console. ... Some command line options to Asterisk only apply when Asterisk is started and cannot be used with remote console mode. If a user tries to use any of these, they are currently simply silently ignored. This prints out a warning if incompatible options are used, informing users that an option used cannot be used with remote console mode. Additionally, some clarifications are added to the help text and man page. ASTERISK-22246 ASTERISK-26582 Change-Id: I980a5380ef2c19e8ea348596396d5382893c4337	3 years ago

Sean Bright	e9e441c399	utf8.c: Add UTF-8 validation and utility functions ... There are various places in Asterisk - specifically in regards to database integration - where having some kind of UTF-8 validation would be beneficial. This patch adds: * Functions to validate that a given string contains only valid UTF-8 sequences. * A function to copy a string (similar to ast_copy_string) stopping when an invalid UTF-8 sequence is encountered. * A UTF-8 validator that allows for progressive validation. All of this is based on the excellent UTF-8 decoder by Björn Höhrmann. More information is available here: https://bjoern.hoehrmann.de/utf-8/decoder/dfa/ The API was written in such a way that should allow us to replace the implementation later should we determine that we need something more comprehensive.

George Joseph	6a0c472374	Scope Tracing: A new facility for tracing scope enter/exit ... What's wrong with ast_debug? ast_debug is fine for general purpose debug output but it's not really geared for scope tracing since it doesn't present its output in a way that makes capturing and analyzing flow through Asterisk easy. How is scope tracing better? Scope tracing uses the same "cleanup" attribute that RAII_VAR uses to print messages to a separate "trace" log level. Even better, the messages are indented and unindented based on a thread-local call depth counter. When output to a separate log file, the output is uncluttered and easy to follow. Here's an example of the output. The leading timestamps and thread ids are removed and the output cut off at 68 columns for commit message restrictions but you get the idea. --> res_pjsip_session.c:3680 handle_incoming PJSIP/1173-00000001 --> res_pjsip_session.c:3661 handle_incoming_response PJSIP/1173 --> res_pjsip_session.c:3669 handle_incoming_response PJSIP/ --> chan_pjsip.c:3265 chan_pjsip_incoming_response_after --> chan_pjsip.c:3194 chan_pjsip_incoming_response P chan_pjsip.c:3245 chan_pjsip_incoming_respon <-- chan_pjsip.c:3194 chan_pjsip_incoming_response P <-- chan_pjsip.c:3265 chan_pjsip_incoming_response_after <-- res_pjsip_session.c:3669 handle_incoming_response PJSIP/ <-- res_pjsip_session.c:3661 handle_incoming_response PJSIP/1173 <-- res_pjsip_session.c:3680 handle_incoming PJSIP/1173-00000001 The messages with the "-->" or "<--" were produced by including the following at the top of each function: SCOPE_TRACE(1, "%s\n", ast_sip_session_get_name(session)); Scope isn't limited to functions any more than RAII_VAR is. You can also see entry and exit from "if", "for", "while", etc blocks. There is also an ast_trace() macro that doesn't track entry or exit but simply outputs a message to the trace log using the current indent level. The deepest message in the sample (chan_pjsip.c:3245) was used to indicate which "case" in a "select" was executed. How do you use it? More documentation is available in logger.h but here's an overview: * Configure with --enable-dev-mode. Like debug, scope tracing is #ifdef'd out if devmode isn't enabled. * Add a SCOPE_TRACE() call to the top of your function. * Set a logger channel in logger.conf to output the "trace" level. * Use the CLI (or cli.conf) to set a trace level similar to setting debug level... CLI> core set trace 2 res_pjsip.so Summary Of Changes: * Added LOG_TRACE logger level. Actually it occupies the slot formerly occupied by the now defunct "event" level. * Added core asterisk option "trace" similar to debug. Includes ability to specify global trace level in asterisk.conf and CLI commands to turn on/off and set levels. Levels can be set globally (probably not a good idea), or by module/source file. * Updated sample asterisk.conf and logger.conf. Tracing is disabled by default in both. * Added __ast_trace() to logger.c which keeps track of the indent level using TLS. It's #ifdef'd out if devmode isn't enabled. * Added ast_trace() and SCOPE_TRACE() macros to logger.h. These are all #ifdef'd out if devmode isn't enabled. Why not use gcc's -finstrument-functions capability? gcc's facility doesn't allow access to local data and doesn't operate on non-function scopes. Known Issues: The only know issue is that we currently don't know the line number where the scope exited. It's reported as the same place the scope was entered. There's probably a way to get around it but it might involve looking at the stack and doing an 'addr2line' to get the line number. Kind of like ast_backtrace() does. Not sure if it's worth it.

George Joseph	d6574cb7c7	message.c: Add option to suppress the Message channel AMI and ARI events ... In order to reduce the amount of AMI and ARI events generated, the global "Message/ast_msg_queue" channel can be set to suppress it's normal channel housekeeping events such as "Newexten", "VarSet", etc. This can greatly reduce load on the manager and ARI applications when the Digium Phone Module for Asterisk is in use. To enable, set "hide_messaging_ami_events" in asterisk.conf to "yes" In Asterisk versions <18, the default is "no" preserving existing behavior. Beginning with Asterisk 18, the option will default to "yes". NOTE: This change does not affect UserEvents or the ARI TextMessageReceived events. * Added the "hide_messaging_ami_events" option to asterisk.conf. * Changed message.c to set the AST_CHAN_TP_INTERNAL property on the "Message/ast_msg_queue" channel if the option is set in asterisk.conf. This suppresses the reporting of the events. Change-Id: Ia2e3516d43f4e0df994fc6598565d6bba2d7018b	5 years ago

Corey Farrell	d61a8791b5	Build System: Improve ccache matching for different menuselect options. ... Changing any Menuselect option in the `Compiler Flags` section causes a full rebuild of the Asterisk source tree. Every enabled option causes a #define to be added to buildopts.h, thus breaking ccache caching for every source file that includes "asterisk.h". In most cases each option only applies to one or two files. Now we only define those options for the specific sources which use them, this causes much better cache matching when working with multiple builds. For example testing code with an without MALLOC_DEBUG will now use just over half the ccache size, only main/astmm.o will have two builds cached instead of every file. Reorder main/Makefile so _ASTCFLAGS set on specific object files are all together, sorted by filename. Stop adding -DMALLOC_DEBUG to CFLAGS of bundled pjproject, this define is no longer used by any header so only serves to break cache. The only code change is a slight adjustment to how main/astmm.c is initialized. Initialization functions always exist so main/asterisk.c can call them unconditionally. Additionally rename the astmm initialization functions so they are not exported. Change-Id: Ie2085237a964f6e1e6fff55ed046e2afff83c027	7 years ago

Corey Farrell	fee929c8ac	core: Remove non-critical cleanup from startup aborts. ... When built-in components of Asterisk fail to start they cause the Asterisk startup to abort. In these cases only the most critical cleanup should be performed - closing databases and terminating proceses. These cleanups are registered using ast_register_atexit, all other cleanups should not be run during startup abort. The main reason for this change is that these cleanup procedures are untestable from the partially initialized states, if they fail it could prevent us from ever running the critical cleanup with ast_run_atexits. Create separate initialization for dns_core.c to be run unconditionally during startup instead of being initialized by the first dns resolver to be registered. This ensures that 'sched' is initialized before it can be potentially used. Replace ast_register_atexit with ast_register_cleanup in media_cache.c.
