Naveen Albert	a2799554d2	pbx_functions.c: Manually update ast_str strlen. When ast_func_read2 is used to read a function using its read function (as opposed to a native ast_str read2 function), the result is copied directly by the function into the ast_str buffer. As a result, the ast_str length remains initialized to 0, which is a bug because this is not the real string length. This can cascade and have issues elsewhere, such as when reading substrings of functions that only register read as opposed to read2 callbacks. In this case, since reading ast_str_strlen returns 0, the returned substring is empty as opposed to the actual substring. This has caused the ast_str family of functions to behave inconsistently and erroneously, in contrast to the pbx_variables substitution functions which work correctly. This fixes this issue by manually updating the ast_str length when the result is copied directly into the ast_str buffer. Additionally, an assertion and a unit test that previously exposed these issues are added, now that the issue is fixed.

George Joseph	1ed15e1815	Geolocation: Base Asterisk Prereqs * Added ast_variable_list_from_quoted_string() Parse a quoted string into an ast_variable list. * Added ast_str_substitute_variables_full2() Perform variable/function/expression substitution on an ast_str. * Added ast_strsep_quoted() Like ast_strsep except you can specify a specific quote character. Also added unit test. * Added ast_xml_find_child_element() Find a direct child element by name. * Added ast_xml_doc_dump_memory() Dump the specified document to a buffer * ast_datastore_free() now checks for a NULL datastore before attempting to destroy it.

Naveen Albert	79689d9df8	func_evalexten: Extension evaluation function. This adds the EVAL_EXTEN function, which may be used to retrieve the variable-substituted data at any extension. ASTERISK-29486 Change-Id: Iad81019689674c9f4ac77d235f5d7234adbb1432	3 years ago
Naveen Albert	3686a97d79	cli: Add command to evaluate dialplan functions. Adds the dialplan eval function commands to evaluate a dialplan function from the CLI. The return value and function result are printed out and can be used for testing or debugging. ASTERISK-29820 #close Change-Id: I833e97ea54c49336aca145330a2adeebfad05209	3 years ago
Naveen Albert	e006d2d2a6	pbx_variables: add missing ASTSBINDIR variable Every config variable in the directories section of asterisk.conf currently has a counterpart built-in variable containing the value of the config option, except for the last one, astsbindir, which should have an ASTSBINDIR variable. However, the actual corresponding ASTSBINDIR variable is missing in pbx_variables.c. This adds the missing variable so that all the config options have their corresponding variable.

Naveen Albert	bb27d5e1fe	pbx_variables: initialize uninitialized variable The variable cp4 in a variable substitution function can potentially be used without being initialized currently. This causes Asterisk to no longer compile. This initializes cp4 to NULL to make the compiler happy. ASTERISK-29803 #close Change-Id: I392579cbb76db2795d5820c9427cf55fbcee9e72	3 years ago
Naveen Albert	c6309af560	pbx_variables: Increase parsing capabilities of MSet Currently MSet can only parse a maximum of 24 variables. If more variables are provided to MSet, the 24th variable will simply contain the remainder of the string and the remaining variables thereafter will never get set. This increases the number of variables that can be parsed in one go from 24 to 99. Additionally, documentation is added since this limitation is currently undocumented and is confusing to users who encounter this limitation.

Naveen Albert	cc1418ef47	pbx: Add variable substitution API for extensions Currently, variable substitution involving dialplan extensions is quite clunky since it entails obtaining the current dialplan location, backing it up, storing the desired variables for substitution on the channel, performing substitution, then restoring the original location. In addition to being clunky, things could also go wrong if an async goto were to occur and change the dialplan location during a substitution. Fundamentally, there's no reason it needs to be done this way, so new API is added to allow for directly passing in the dialplan location for the purposes of variable substitution so we don't need to mess with the channel information anymore. Existing API is not changed. ASTERISK-29745 #close Change-Id: I23273bf27fa0efb64a606eebf9aa8e2f41a065e4	3 years ago
lvl	92fcd4edba	Introduce astcachedir, to be used for temporary bucket files As described in the issue, /tmp is not a suitable location for a large amount of cached media files, since most distributions make /tmp a RAM-based tmpfs mount with limited capacity. I opted for a location that can be configured separately, as opposed to using a subdirectory of spooldir, given the different storage profile (transient files vs files that might stay there indefinitely). This commit just makes the cache directory configurable, but leaves it at /tmp by default, to ensure backwards compatibility. A future commit that only targets master could change the default location to something more sensible such as /var/tmp/asterisk. At that point, the cachedir could be created and cleaned up during uninstall by the Makefile script. ASTERISK-29143 Change-Id: Ic54e95199405abacd9e509cef5f08fa14c510b5d	4 years ago
Kevin Harwell	3d1bf3c537	Compiler fixes for gcc 10 This patch fixes a few compile warnings/errors that now occur when using gcc 10+. Also, the Makefile.rules check to turn off partial inlining in gcc versions greater or equal to 8.2.1 had a bug where it only it only checked against versions with at least 3 numbers (ex: 8.2.1 vs 10). This patch now ensures any version above the specified version is correctly compared. Change-Id: I54718496eb0c3ce5bd6d427cd279a29e8d2825f9	5 years ago
Kevin Harwell	bdd785d31c	various files - fix some alerts raised by lgtm code analysis This patch fixes several issues reported by the lgtm code analysis tool: https://lgtm.com/projects/g/asterisk/asterisk Not all reported issues were addressed in this patch. This patch mostly fixes confirmed reported errors, potential problematic code points, and a few other "low hanging" warnings or recommendations found in core supported modules. These include, but are not limited to the following: * innapropriate stack allocation in loops * buffer overflows * variable declaration "hiding" another variable declaration * comparisons results that are always the same * ambiguously signed bit-field members * missing header guards Change-Id: Id4a881686605d26c94ab5409bc70fcc21efacc25	6 years ago
Richard Mudgett	2f78dc2bfa	pbx_variables.c: Misc fixes in variable substitution. * Copy more than one character at a time when there is nothing to substitute. * Fix off by one error if a '}' or ']' is missing. * Eliminated the requirement that the "used" parameter had to point to a variable. The current callers were always declaring a variable to meet the requirement and discarding the value put into that variable. Now it can be NULL. * In ast_str_substitute_variables_full() fixed using the bogus channel to evaluate a function. We were not using the bogus channel we just created to help evaluate a subexpression. Change-Id: Ia83d99f4f16abe47f329eb39b6ff2013ae7c9854	7 years ago
Corey Farrell	a6e5bae3ef	Remove ASTERISK_REGISTER_FILE. ASTERISK_REGISTER_FILE no longer has any purpose so this commit removes all traces of it. Previously exported symbols removed: * __ast_register_file * __ast_unregister_file * ast_complete_source_filename This also removes the mtx_prof static variable that was declared when MTX_PROFILE was enabled. This variable was only used in lock.c so it is now initialized in that file only. ASTERISK-26480 #close Change-Id: I1074af07d71f9e159c48ef36631aa432c86f9966	9 years ago
