2015-05-29Don't #include "lldb-python.h" from anywhere.Zachary Turner
Since interaction with the python interpreter is moving towards being more isolated, we won't be able to include this header from normal files anymore, all includes of it should be localized to the python library which will live under source/bindings/API/Python after a future patch. None of the files that were including this header actually depended on it anyway, so it was just a dead include in every single instance. llvm-svn: 238581

2015-04-17Add a "force_kill" arg to Process::Destroy(). This is needed afterJason Molenda
the changes in r233255/r233258. Normally if lldb attaches to a running process, when we call Process::Destroy, we want to detach from the process. If lldb launched the process itself, ::Destroy should kill it. However, if we attach to a process and the driver calls SBProcess::Kill() (which calls Destroy), we need to kill it even if we didn't launch it originally. The force_kill param allows for the SBProcess::Kill method to force the behavior of Destroy. <rdar://problem/20424439> llvm-svn: 235158

2015-02-11Lock mutex in the same order.Hafiz Abid Qadeer
SBProcess uses 2 mutexex; RunLock and APILock. Apart from 2 places, RunLock is locked before API lock. I have fixed the 2 places where order was different. I observed a deadlock due to this different order in lldb-mi once. Although lldb-mi command and event thread dont run at the same time now. So it can not deadlock there but can still be problem for some other clients. Pre-approved by Greg in http://lists.cs.uiuc.edu/pipermail/lldb-dev/2015-February/006509.html llvm-svn: 228844
2014-10-21Make the "synchronous" mode actually work without race conditions.Greg Clayton
There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be. llvm-svn: 220254

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda. It builds cleanly against TOT llvm with xcodebuild. I updated the cmake files by visual inspection but did not try a build. I haven't built these sources on any non-Mac platforms - I don't think this patch adds any code that requires darwin, but please let me know if I missed something.

2013-10-31Fix the format warnings.Sylvestre Ledru
In almost all cases, the misuse is about "%lu" being used instead of the correct "%zu" (even though these are compatible on 64-bit platforms in practice). There are even a couple of cases where "%ld" (ie., signed int) is used instead of "%zu", and one where "%lu" is used instead of "%" PRIu64. Fixes bug #17551.

2013-03-27<rdar://problem/13521159>Greg Clayton
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. llvm-svn: 178191

Added the ability for OS plug-ins to lazily populate the thread this. The python OS plug-in classes can now implement the following method: class OperatingSystemPlugin: def create_thread(self, tid, context): # Return a dictionary for a new thread to create it on demand This will add a new thread to the thread list if it doesn't already exist. The example code in lldb/examples/python/operating_system.py has been updated to show how this call us used. Cleaned up the code in PythonDataObjects.cpp/h: - renamed all classes that started with PythonData* to be Python*. - renamed PythonArray to PythonList. Cleaned up the code to use inheritance where - Centralized the code that does ref counting in the PythonObject class to a single function. - Made the "bool PythonObject::Reset(PyObject *)" function be virtual so each subclass can correctly check to ensure a PyObject is of the right type before adopting the object. - Cleaned up all APIs and added new constructors for the Python* classes to they can all construct form: - PyObject * - const PythonObject & - const lldb::ScriptInterpreterObjectSP & Cleaned up code in ScriptInterpreterPython: - Made calling python functions safer by templatizing the production of value formats. Python specifies the value formats based on built in C types (long, long long, etc), and code often uses typedefs for uint32_t, uint64_t, etc when passing arguments down to python. We will now always produce correct value formats as the templatized code will "do the right thing" all the time. - Fixed issues with the ScriptInterpreterPython::Locker where entering the session and leaving the session had a bunch of issues that could cause the "lldb" module globals lldb.debugger, lldb.target, lldb.process, lldb.thread, and lldb.frame to not be initialized. llvm-svn: 172873
2013-01-16<rdar://problem/13009943>Greg Clayton
Added a unique integer identifier to processes. Some systems, like JTAG or other simulators, might always assign the same process ID (pid) to the processes that are being debugged. In order for scripts and the APIs to uniquely identify the processes, there needs to be another ID. Now the SBProcess class has: uint32_t SBProcess::GetUniqueID(); This integer ID will help to truly uniquely identify a process and help with appropriate caching that can be associated with a SBProcess object. llvm-svn: 172628

2012-10-04Ran the sources through the compiler with -Wshadow warningsJason Molenda
enabled after we'd found a few bugs that were caused by shadowed local variables; the most important issue this turned up was a common mistake of trying to obtain a mutex lock for the scope of a code block by doing Mutex::Locker(m_map_mutex); This doesn't assign the lock object to a local variable; it is a temporary that has its dtor called immediately. Instead, Mutex::Locker locker(m_map_mutex); does what is intended. For some reason -Wshadow happened to highlight these as shadowed variables. I also fixed a few obivous and easy shadowed variable issues across the code base but there are a couple dozen more that should be fixed when someone has a free minute. <rdar://problem/12437585> llvm-svn: 165269

2012-08-29<rdar://problem/11757916>Greg Clayton
Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. llvm-svn: 162860
2012-08-22Rework how the API mutex is acquired when filling out an ExecutionContext ↵Jim Ingham
from an ExecutionContextRef, particularly in the SBThread & SBFrame interfaces. Instead of filling the whole context & then getting the API mutex, we now get only the target, acquire the API mutex from it, then fill out the rest of the context. This removes a race condition where you get a ThreadSP, then wait on the API mutex while another command Destroy's the Thread you've just gotten. Also fixed the ExecutionContextRef::Get*SP calls so they don't return invalid objects. Also fixed the ExecutionContext::Has*Scope calls so they don't claim to have a scope if the object representing that scope has been destroyed. Also fixed a think-o in Thread::IsValid which was causing it to return the opposite of the desired value. <rdar://problem/11995490> llvm-svn: 162401
2012-07-27Added an lldb_private & equivalent SB API to send an AsyncInterrupt to the ↵Jim Ingham
event loop. Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the event loop. If you are attaching and get an async interrupt, abort the attach attempt. Also remember to destroy the process if get interrupted while attaching. Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends. <rdar://problem/10792425> llvm-svn: 160903

2012-07-12<rdar://problem/11791234>Greg Clayton
Fixed a case where the python interpreter could end up holding onto a previous lldb::SBProcess (probably in lldb.process) when run under Xcode. Prior to this fix, the lldb::SBProcess held onto a shared pointer to a lldb_private::Process. This in turn could cause the process to still have a thread list with stack frames. The stack frames would have module shared pointers in the lldb_private::SymbolContext objects. We also had issues with things staying in the shared module list too long when we found things by UUID (we didn't remove the out of date ModuleSP from the global module cache). Now all of this is fixed and everything goes away between runs. llvm-svn: 160140

2012-04-06Added logging when API calls try to do something that shouldn't be done when ↵Greg Clayton
the process is stopped by having logging calls that end with "error: process is running". Also test for the process to be stopped when many SBValue API calls are made to make sure it is safe to evaluate values, children of values and much more. llvm-svn: 154160
2012-04-05Added a new Host class: ReadWriteLockGreg Clayton
This abstracts read/write locks on the current host system. It is currently backed by pthread_rwlock_t objects so it should work on all unix systems. We also need a way to control multi-threaded access to the process through the public API when it is running. For example it isn't a good idea to try and get stack frames while the process is running. To implement this, the lldb_private::Process class now contains a ReadWriteLock member variable named m_run_lock which is used to control the public process state. The public process state represents the state of the process as the client knows it. The private is used to control the actual current process state. So the public state of the process can be stopped, yet the private state can be running when evaluating an expression for example. Adding the read/write lock where readers are clients that want the process to stay stopped, and writers are clients that run the process, allows us to accurately control multi-threaded access to the process. Switched the SBThread and SBFrame over to us shared pointers to the ExecutionContextRef class instead of making their own class to track this. This fixed an issue with assigning on SBFrame to another and will also centralize the code that tracks weak references to execution context objects into one location. llvm-svn: 154099
