Vicențiu Ciorbaru	26e5f9dda1	MDEV-14229: Stack trace is not resolved for shared objects Resolving a stacktrace including functions in dynamic libraries requires us to look inside the libraries for the symbols. Addr2line needs to be started with the correct binary for each address on the stack. To do this, figure out which library it is using dladdr, then if the addr2line binary was started with a different binary, fork it again with the correct one. We only have one addr2line process running at any point during the stacktrace resolving step. The maximum number of forks for addr2line should generally be around 6. One for server stacktrace code, one for plugin code, one when going back into server code, one for pthread library, one for libc, one for the _start function in the server. More can come up if plugin calls server function which goes back to a plugin, etc.	8 years ago

Sergei Golubchik	d92009231d	a couple of minor post-5.5-merge cleanups include/mysql_com.h: remove "shutdown levels" that aren't shutdown levels from mysql_enum_shutdown_level mysys/my_addr_resolve.c: my_snprintf in 5.5 (but not in 5.3) supports %p sql/item_func.cc: use a method (that exists only in 5.5) instead of directly accessing a member sql/item_subselect.cc: use a method (that exists only in 5.5) instead of directly accessing a member sql/opt_subselect.cc: use a method (that exists only in 5.5) instead of directly accessing a member sql/sql_select.cc: use a method (that exists only in 5.5) instead of directly accessing a member	14 years ago
Sergei Golubchik	00f2e3139f	alternative method of resolving addresses for safemalloc and crash handler. don't link with libbfd, exec addr2line, if it's available at run time	14 years ago
Sergei Golubchik	db8f698c8a	new configure option: NOT_FOR_DISTRIBUTION fix safemalloc to compile w/o libbfd. CMakeLists.txt: NOT_FOR_DISTRIBUTION option cmake/readline.cmake: simplify libedit/readline detection. never use bundled libedit. use system readline v6 only if NOT_FOR_DISTRIBUTION=1 configure.cmake: use libbfd only if NOT_FOR_DISTRIBUTION=1 include/my_stacktrace.h: link with libbfd even w/o safemalloc.	14 years ago
