LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down. All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@178191 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-27Implementing the notion of externally-acquirable ScriptInterpreter lockEnrico Granata
With this notion, if parties outside the ScriptInterpreter itself need to acquire a lock on script APIs, they can do so by a pattern like this: { auto lock = interpeter->AcquireInterpreterLock(); // do whatever you need to do... } // lock will automatically be released here This might be useful for classes that use the Python convenience objects (e.g. PythonDictionary) to ensure they keep the underlying interpreter in a safe and controlled condition while they call through the C API functions Of course, the ScriptInterpreter still manages its internal locking correctly when necessary :-) git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@178189 91177308-0d34-0410-b5e6-96231b3b80d8

Make register read and write accept $<regname> as valid. This allows: (lldb) reg read rbx rbx = 0x0000000000000000 (lldb) reg read $rbx rbx = 0x0000000000000000 (lldb) reg write $rbx 1 (lldb) reg read $rbx rbx = 0x0000000000000001 to function correctly It is not done at the RegisterContext level because we should keep the internal API clean of this user-friendly behavior and name registers appropriately.

Ensure that option -Y also works for expression as it does for frame variable Also, if the user passes an explicit format specifier when printing a variable, override the summary's decision to hide the value. This is required for scenarios like this to work: (lldb) p/x c (Class) $0 = 0x0000000100adb7f8 NSObject Previously this would say: (lldb) p/x c (Class) $0 = NSObject ignoring the explicit format specifier git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@177893 91177308-0d34-0410-b5e6-96231b3b80d8

Making value objects properly iterable in constructs of the form [ x for x in value_with_children ] This would previously cause an endless loop because lacking a proper iterator object, Python will keep calling __getitem__() with increasing values of the index until it gets an IndexError since SBValue::GetValueForExpressionPath() supports synthetic array members, no array index will ever really cause an IndexError to be raised, hence the endless iteration class value_iter is an implementation of __iter__() that provides a terminating iterator over a value git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@177885 91177308-0d34-0410-b5e6-96231b3b80d8
