2015-11-02Turn off -Wdate-time for crasherDan Willemsen
This is an optional diagnostic tool where it's useful to know if you are running the version that you just built. Allow the use of __TIME__ without a warning or error. Bug: 24204119 Change-Id: I78063c2694b80ccaf5891d1cd649ea17eda978cb

2015-07-01Replace all _LOG error calls with ALOGE.Christopher Ferris
The debuggerd code sometimes calls _LOG(..., logtype::ERROR, ...) and sometimes ALOGE(). Standardize on ALOGE since the _LOG message will wind up in the tombstone in weird places, but using ALOGE will wind up in the logcat portion of the tombstone.

2015-06-03Change the 64 bit map address format.Christopher Ferris
Previously, the map printing in tombstones for 64 bit devices uses a variable length value. This means that the maps are not lined up. The new format is to print the map as 00000000'00000000 in all ways. Also fix a bug where the backtrace_map_t did not initialize all parameters. Add unit tests for all of the dump_all_maps function.

2015-05-27Refactor dump_memory function.Christopher Ferris
- Add dumping memory around registers for x86/x86_64. - Add unit tests for new dump_memory function. - Cleanup all of the machine.cpp files. - Increase the high address check for 32 bit, and decrease the high address allowed for 64 bit slightly to match mips64.

2015-03-17Print the build id of shared libraries if present.Christopher Ferris
For every map that has a name, and if it's a mapped in shared library, print the build id. Refactor the way dump_all_maps logs data. Refactor the way stack segments are dumped. Bug: 19371018 Change-Id: Ic08d05a4b13f128925743936fb84d8059f7cb56f

2015-01-20Move 32 bit/64 bit check into debuggerd.Christopher Ferris
On 64 bit systems, calls to dump_backtrace_to_file or dump_tombstone try and directly contact the correct debuggerd (32 bit vs 64 bit) by reading the elf information for the executable. Unfortunately, system_server makes a call to dump_backtrace_to_file and it doesn't have permissions to read the executable data, so it defaults to always contacting the 64 bit debuggerd. This CL changes the code so that all dump requests go to the 64 bit debuggerd, which reads the elf information and redirects requests for 32 bit processes to the 32 bit debuggerd. Testing: - Forced the watchdog code in system_server to dump stacks and verified that all native stacks are dumped correctly. - Verified that dumpstate and bugreport still properly dump the native processes on a 64 bit and 32 bit system. - Intentionally forced the 64 bit to 32 bit redirect to write only a byte at a time and verified there are no errors, and no dropped data. - Used debuggerd and debuggerd64 to dump 32 bit and 64 bit processes seemlessly. - Used debuggerd on a 32 bit system to dump native stacks.

2014-01-10Move to C++ for debuggerd.Christopher Ferris
This is part 1, only including the bare minimum changes because our diff tool doesn't easily show differences when a file moves. This also breaks it into a small chunk in case some other changes break things, as unlikely as I think that will be. Change-Id: Ib7a3e7a2cc1ac574d15b65fda23813ebcf5d31af

2012-06-08Enhance native stack dumps.Jeff Brown
Provides a new mechanism for dumpstate (while running as root) to request that debuggerd dump the stacks of native processes that we care about in bug reports. In this mode, the backtrace is formatted to look similar to a Dalvik backtrace. Moved the tombstone generating code into a separate file to make it easier to maintain. Fixed a bug where sometimes the stack traces would be incomplete because we were not waiting for each thread to stop after issuing PTRACE_ATTACH, only the main thread. So sometimes we were missing traces for some threads. Refactored the logging code to prevent accidentally writing data to logcat when explicitly dumping a tombstone or backtrace from the console. Only root or system server can request to dump backtraces but only root can dump tombstones. Bug: 6615693 Change-Id: Ib3edcc16f9f3a687e414e3f2d250d9500566123b

2010-05-24debuggerd: Show function names in tombstone backtracesMeng Hu
This change enables debuggerd to provide backtraces with function names in tombstone files and log messages. It does this by reading the image file that the address is found in, and parsing the dynamic symbol table to try to extract the symbol corresponding to the given address. This works best when "-Wl,-export-dynamic" is added to the LDFLAGS of each library and executable, because this will cause all symbols to be added to the dynamic symbol table. If this flag is not present, it will still work, but it will only be able to identify functions which are part of the external API of the library/executable.
