* Don't stall waiting for target to crashAndy McFadden2011-08-041-4/+28
| | | | | | | | | | | This modifies debuggerd to sleep-poll while waiting for the target process to crash, rather than block (potentially forever). Also, add/fix some error reporting. Bug 5035703 Change-Id: Id62ab79f53104927f8de684dff1a5734dbdb8390
* debuggerd can't handle debuggerd crashesAndy McFadden2011-07-291-0/+12
| | | | | | | | | | | | | | When a process receives a fatal signal, it connects to debuggerd and initiates a conversation over a socket. When the crashing process is debuggerd, the conversation stalls forever, and you stop getting native crash details. This resets the signal handlers to SIG_DFL, so that debuggerd simply crashes and gets restarted. Bug 5035703 Change-Id: Ie081d710d046f701bca7e7d8ea3e1d24766d9f61

* debuggerd: properly unblock signal handler.David 'Digit' Turner2011-01-211-1/+13
| | | | | | | | | | | | | This change ensures that debuggered properly releases the signal handler that invoked it after the PTRACE_ATTACH. The previous code simply did a close() of the file descriptor, but for some reason, this didn't always make the read() blocking the signal handler exit. Instead, the thread would stay blocked and never fault, preventing the generation of a useful stack trace. Change-Id: I6b0579041165a710d74ec1bece113ff7b828aed4

| * debuggerd: Show function names in tombstone backtracesMeng Hu2010-05-241-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Minor tweaks to debuggerd.Andy McFadden2009-12-011-7/+8
|/ | | | | | | | | | Changed "process has crashed" message: - say ":5039" instead of ":port" so mouse-paste of command is trivial - removed trailing spaces, which consume log buffer to little effect - improved (I hope) the short explanation of what's going on and what the HOME key does Fixed typo ("ignorning").

| | | | 8 more lines should provide more crucial information in weird cases.
