2016-10-27Remove ASTERISK_REGISTER_FILE.Corey Farrell
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

2015-05-13MALLOC_DEBUG: Replace WRAP_LIBC_MALLOC with ASTMM_LIBC.Corey Farrell
There are 3 ways that calls directly to standard allocator functions can be dealt with: 1. Block their use, cause them to generate an error. This is the default. 2. Replace them with the Asterisk equivalent function calls. 3. Leave them alone. This change allows one of these 3 options to be selected by any source. The source just needs to define ASTMM_LIBC to ASTMM_BLOCK, ASTMM_REDIRECT, or ASTMM_IGNORE to use option 1, 2 or 3 respectively. Normally ASTMM_BLOCK is the correct option, so it is default when ASTMM_LIBC is not defined. In some cases when building 3rd party code it is desirable to have it use Asterisk functions, without changing the whole source - ASTMM_REDIRECT accomplishes this. When using 3rd party libraries sometimes a static inline function will make use of malloc or free. In these cases it may be unsafe to replace the allocator in the header, as it's possible the memory could be freed by the library using standard allocators. For those cases ASTMM_IGNORE is needed.

2015-04-13git migration: Refactor the ASTERISK_FILE_VERSION macroMatt Jordan
Git does not support the ability to replace a token with a version string during check-in. While it does have support for replacing a token on clone, this is somewhat sub-optimal: the token is replaced with the object hash, which is not particularly easy for human consumption. What's more, in practice, the source file version was often not terribly useful. Generally, when triaging bugs, the overall version of Asterisk is far more useful than an individual SVN version of a file. As a result, this patch removes Asterisk's support for showing source file versions. Specifically, it does the following: * Rename ASTERISK_FILE_VERSION macro to ASTERISK_REGISTER_FILE, and remove passing the version in with the macro. Other facilities than 'core show file version' make use of the file names, such as setting a debug level only on a specific file. As such, the act of registering source files with the Asterisk core still has use. The macro rename now reflects the new macro purpose. * main/asterisk: - Refactor the file_version structure to reflect that it no longer tracks a version field. - Remove the "core show file version" CLI command. Without the file version, it is no longer useful. - Remove the ast_file_version_find function. The file version is no longer tracked. - Rename ast_register_file_version/ast_unregister_file_version to ast_register_file/ast_unregister_file, respectively. * main/manager: Remove value from the Version key of the ModuleCheck Action. The actual key itself has not been removed, as doing so would absolutely constitute a backwards incompatible change. However, since the file version is no longer tracked, there is no need to attempt to include it in the Version key. * UPGRADE: Add notes for: - Modification to the ModuleCheck AMI Action - Removal of the "core show file version" CLI command Change-Id: I6cf0ff280e1668bf4957dc21f32a5ff43444a40e
2015-03-26Replace most uses of ast_register_atexit with ast_register_cleanup.Corey Farrell
Since 'core stop now' and 'core restart now' do not stop modules, it is unsafe for most of the core to run cleanups. Originally all cleanups used ast_register_atexit, and were only changed when it was shown to be unsafe. ast_register_atexit is now used only when absolutely required to prevent corruption and close child processes. Exceptions that need to use ast_register_atexit: * CDR: Flush records. * res_musiconhold: Kill external applications. * AstDB: Close the DB. * canary_exit: Kill canary process.

2013-06-08Add backtrace generation to MALLOC_DEBUG memory corruption reportsMatthew Jordan
This patch allows astmm to access the backtrace generation code in Asterisk. When memory is allocated, a backtrace is created and stored with the memory region that tracks the allocation. If a memory corruption is detected, the backtrace is printed to the astmm log. The backtrace will make use of the BETTER_BACKTRACES build option if available. As a result, this patch moves the backtrace generation code into its own file and uses the non-wrapped versions of the C library memory allocation routines. This allows the memory allocation code to safely use the backtrace generation routines without infinitely recursing.

2012-11-08Add MALLOC_DEBUG enhancements.Richard Mudgett
* Makes malloc() behave like calloc(). It will return a memory block filled with 0x55. A nonzero value. * Makes free() fill the released memory block and boundary fence's with 0xdeaddead. Any pointer use after free is going to have a pointer pointing to 0xdeaddead. The 0xdeaddead pointer is usually an invalid memory address so a crash is expected. * Puts the freed memory block into a circular array so it is not reused immediately. * When the circular array rotates out a memory block to the heap it checks that the memory has not been altered from 0xdeaddead. * Made the astmm_log message wording better. * Made crash if the DO_CRASH menuselect option is enabled and something is found. * Fixed a potential alignment issue on 64 bit systems. struct ast_region.data[] should now be aligned correctly for all platforms. * Extracted region_check_fences() from __ast_free_region() and handle_memory_show(). * Updated handle_memory_show() CLI usage help.

build times - tested, there is no measureable difference before and after this commit.

Normally, source files should not include any of the above system headers, and instead use either "asterisk.h" or "asterisk/compat.h" which does it better.

https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r78095 | russell | 2007-08-03 14:39:49 -0500 (Fri, 03 Aug 2007) | 28 lines Add some improvements to lock debugging. These changes take effect with DEBUG_THREADS enabled and provide the following: * This will keep track of which locks are held by which thread as well as which lock a thread is waiting for in a thread-local data structure. A reference to this structure is available on the stack in the dummy_start() function, which is the common entry point for all threads. This information can be easily retrieved using gdb if you switch to the dummy_start() stack frame of any thread and print the contents of the lock_info variable. * All of the thread-local structures for keeping track of this lock information are also stored in a list so that the information can be dumped to the CLI using the "core show locks" CLI command. This introduces a little bit of a performance hit as it requires additional underlying locking operations inside of every lock/unlock on an ast_mutex. However, the benefits of having this information available at the CLI is huge, especially considering this is only done in DEBUG_THREADS mode. It means that in most cases where we debug deadlocks, we no longer have to request access to the machine to analyze the contents of ast_mutex_t structures. We can now just ask them to get the output of "core show locks", which gives us all of the information we needed in most cases. I also had to make some additional changes to astmm.c to make this work when both MALLOC_DEBUG and DEBUG_THREADS are enabled. I disabled tracking of one of the locks in astmm.c because it gets used inside the replacement memory allocation routines, and the lock tracking code allocates memory. This caused infinite recursion. ........ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@78096 65c4cc65-6c06-0410-ace0-fbb531ad65f3

2006-08-21various cleanups, including ...Russell Bryant
- Create an astmm_log() macro that logs the same message to both stderr as well as the mmlog file if it is open instead of duplicating the code everywhere. - Use for loops for list traversals instead of while loops - reduce nesting - ensure locking isn't put around more than is necessary - localize a struct definition - change the limit of the path to the mmlog to PATH_MAX instead of 80 git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@40780 65c4cc65-6c06-0410-ace0-fbb531ad65f3
