Arguments:
|

dump_directory: The directory in which to look for minidumps.
|

symbols_path: The path to symbols to use for dump processing.
|

This can either be a path to a directory

containing Breakpad-format symbols, or a URL
|

to a zip file containing a set of symbols.
|

stackwalk_binary: The path to the minidump_stackwalk binary.
|
||||
If not set, the environment variable
|
||||
MINIDUMP_STACKWALK will be checked.
|
||||
dump_save_path: A directory in which to copy minidump files
|
||||
for safekeeping. If not set, the environment
|
||||
variable MINIDUMP_SAVE_PATH will be checked.
|
||||
test_name: The test name to be used in log output.
|
||||
`dump_directory` will be searched for minidump files. Any minidump files found will
|
||||
have `stackwalk_binary` executed on them, with `symbols_path` passed as an extra
|
||||
argument.
|
||||
|
||||
`stackwalk_binary` should be a path to the minidump_stackwalk binary.
|
||||
If `stackwalk_binary` is not set, the MINIDUMP_STACKWALK environment variable
|
||||
will be checked and its value used if it is not empty.
|
||||
|
||||
`symbols_path` should be a path to a directory containing symbols to use for
|
||||
dump processing. This can either be a path to a directory containing Breakpad-format
|
||||
symbols, or a URL to a zip file containing a set of symbols.
|
||||
|
||||
If `dump_save_path` is set, it should be a path to a directory in which to copy minidump
|
||||
files for safekeeping after a stack trace has been printed. If not set, the environment
|
||||
variable MINIDUMP_SAVE_PATH will be checked and its value used if it is not empty.
|
||||
|
||||
If `test_name` is set it will be used as the test name in log output. If not set the
|
||||
filename of the calling function will be used.
|
||||

||||
Returns True if any minidumps were found, False otherwise.
