* [NativeProcessLinux] Fix handling of SIGSTOPPavel Labath2015-05-211-25/+9
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously, NPL tried to reinject SIGSTOP into the inferior in an attempt to get the process to start in the group-stop state. This was: a) wrong (reinjection should be controlled by "process handle" lldb setting) b) racy (it should use Resume for transparent resuming instead of RequestResume) c) broken (llgs crashed on inferior SIGSTOP) With this change, SIGSTOP is handled just like any other signal delivered to the inferior: we stop all threads and report signal reception to lldb. SIGSTOP reinjection does not behave the same way as it would outside the debugger, but simulating this is a hard problem and is not normally necessary. Test Plan: I have added a test which verifies we get SIGSTOP reports and we do not crash.

* [NativeProcessLinux] Fix removal of temporary breakpointsPavel Labath2015-05-152-19/+21
| | | | | | | | | | | | | | | | | | | | | | Summary: There was an issue in NPL, where we attempted removal of temporary breakpoints (used to implement software single stepping), while some threads of the process were running. This is a problem since we currently always use the main thread's ID in the removal ptrace call. Therefore, if the main thread was still running, the ptrace call would fail, and the software breakpoint would remain, causing all kinds of problems. This change removes the breakpoints after all threads have stopped. This fixes TestExitDuringStep on Android arm and can also potentially help in other situations, as previously the breakpoint would not get removed if the thread stopped for another reason. Test Plan: TestExitDuringStep passes, other tests remain unchanged.

* [NativeProcessLinux] Fix potential race during thread exitPavel Labath2015-05-151-31/+7
| | | | | | | | | | | | | | | | | | | Summary: This is the same issue as we had in D9145 for thread creation. Going through the full ThreadDidStop/RequestResume cycle can cause a deferred notification to fire, which is not correct when we are ignoring an event and resuming the thread. In this case it doesn't matter much since the thread will die after that anyway, but for correctness, we should do the same thing here. Also treating the SIGTRAP case the same way. Test Plan: Tests continue to pass. Reviewers: chaoren, ovyalov Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D9696 llvm-svn: 237445
* Fix StopInfoWatchpoint handling after r237411Pavel Labath2015-05-151-1/+3
| | | | | | | | | | | | r237411 exposed the following issue: ProcessGDBRemote used the description field in the stop-reply to set the description of the StopInfo. In the case of watchpoints, the packet description contains the raw address that got hit, which is not exactly the information we want to display to the user as the stop info. Therefore, I have changed the code to use the packet description only if the StopInfo does not already have a description. This makes the behavior equivalent to the pre-r237411 behavior as then the SetDecription call got ignored for watchpoints. llvm-svn: 237436

* Remote Non-Stop SupportEwan Crawford2015-05-135-7/+104
| | | | | | | | | | | | | | | | | | | | Summary: This patch is the beginnings of support for Non-stop mode in the remote protocol. Letting a user examine stopped threads, while other threads execute freely. Non-stop mode is enabled using the setting target.non-stop-mode, which sends a QNonStop packet when establishing the remote connection. Changes are also made to treat the '?' stop reply packet differently in non-stop mode, according to spec https://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Non_002dStop.html#Remote-Non_002dStop. A setting for querying the remote for default thread on setup is also included. Handling of '%' async notification packets will be added next.

* Remove handling of eStateStopped from NativeProcessLinux::ResumePavel Labath2015-05-122-135/+8
| | | | | | | | | | | | | | | | | | | | | | | Summary: NPL::Resume attempted to handle eStateStopped as a resume action. However: - GDBRemoteCommunicationServerLLGS (the only user of NPL) never sets this action - it could set this action in response to a vCont:t packet, but LLDB never produces this packet - gdb-remote protocol documentation says vCont:t packet is used only in non-stop mode, but LLDB does not support non-stop mode - even if LLDB supported non-stop mode, this implementation of eStateStopped does something different from what the spec says it should (according to spec, it should stop the specified thread, but this seems to want to stop all threads). Given the facts above, I believe we should remove this unused and untested code, as it probably doesn't even work and removing it makes the rest of the code noticably simpler.

* [NativeProcessLinux] Remove the post-stop lambdaPavel Labath2015-05-062-132/+55
| | | | | | | | | | | | | | | | | | | | | | | Summary: The lambda was always calling SetState(eStateStopped) with small variations, so I have inlined the code. Given that we don't have the TSC anymore, I believe we don't need to be so generic. The only major change here is the way we choose a stop reason thread when we're interrupting a program on client request. Previously, we were setting a null stop reason for all threads and then fixing up the reason for one victim thread in the lambda. Now, I make sure the stop reason is set for the victim thread correctly in the first place. I also take the opportunity to rename CallAfter* functions into something more appropriate.

* [NativeProcessLinux] fold ThreadStateCoordinator into NPLPavel Labath2015-05-065-918/+849
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Since all TSC operations are now executed synchronously, TSC has become a little more than a messenger between different parts of NativeProcessLinux. Therefore, the reason for its existance has disappeared. This commit moves the contents of the TSC into the NPL class. This will enable us to remove all the boilerplate code in NPL (as it stands now, this is most of the class), which I plan to do in subsequent commits. Unfortunately, this also means we will lose the unit tests for the TSC. However, since the size of the TSC has diminished, the unit tests were not testing much at this point anyway, so it's not a big loss. No functional change. Test Plan: All tests continue to pass.

* [NativeProcessLinux] Get rid of the thread state coordinator threadPavel Labath2015-05-054-253/+126
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change removes the thread state coordinator thread by making all the operations it was performing synchronous. In order to prevent deadlock, NativeProcessLinux must now always call m_monitor->DoOperation with the m_threads_mutex released. This is needed because HandleWait callbacks lock the mutex (which means the monitor thread will block waiting on whoever holds the lock). If the other thread now requests a monitor operation, it will wait for the monitor thread do process it, creating a deadlock. To preserve this invariant I have introduced two new Monitor commands: "begin operation block" and "end operation block". They begin command blocks the monitor from processing waitpid events until the corresponding end command, thereby assuring the monitor does not attempt to acquire the mutex. Test Plan: Run the test suite locally, verify no tests fail. Reviewers: vharron, chaoren Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D9227 llvm-svn: 236501

* [NativeProcessLinux] Add back synchronisation of thread create eventsPavel Labath2015-04-282-15/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Without the synchronisation between the two thread creation events the following case could happen: - threads A and B are running. A hits a breakpoint. We note that we want to stop B. - before we could stop it, B creates a new thread C, we get the stop notification for B, but we don't record C's existence yet. - we resume B - before we get the C notification, B stops again (e.g. hits a breakpoint, gets our SIGSTOP, etc.) - we see all known threads have stopped, and we notify LLDB - C notification comes, we note it's existence and resume it => we have an inconsistent state (LLDB thinks we've stopped, but C is running) I resolve this by doing a blocking wait for for the C notification when we get the creation notification on the parent (B) thread. This way the two events are synchronised, but we don't need to introduce the intermediate "launching" state which would complicate handling of thread states as all code would need to be aware of the third possible state. Test Plan: This is an obscure corner case, which I had not observed in practise, so I have no test for it. I have tested that this commit does not regress in existing tests though.

* [NativeProcessLinux] Fix race condition during inferior thread creationPavel Labath2015-04-234-134/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following situation occured if we were stopping a process (due to breakpoint, watchpoint, ... hit) while a new thread was being created. - process has two threads: A and B. - thread A hits a breakpoint: we send a STOP signal to thread B and register a callback with ThreadStateCoordinator to send a stop notification after the thread stops. - thread B stops, but not due to the SIGSTOP, but on a thread creation event (of a new thread C). We are unaware of our desire to stop, so we queue ThreadStopped and RequestResume operations with TSC, so the thread can continue running. - TSC receives the ThreadStopped event, sees that all threads are stopped and fires the delayed stop notification. - immediately after that TSC gets the RequestResume operation, so it resumes the thread. At this point the state is inconsistent because LLDB thinks the process is stopped and will start issuing commands to it, but one of the threads is in fact running. Things eventually break. I address this problem by omitting the two TSC events altogether and Resuming the thread B directly. This way the short stop is invisible to the TSC and the delayed notification will not fire. We will fire the notification when we actually process the SIGSTOP on thread B. When we get the initial SIGSTOP for thread C, we also resume the thread and send a ThreadWasCreated message (is_stopped = false) to the TSC. This way, the TSC can stop the thread on its own and handle the stop event later. This way the state of the new thread is correctly handled as well (thanks Chaoren for the idea). This patch also removes the synchronisation between the thread creation notifications on threads B and C. The need for this synchronisation is unclear (the comments seem to hint that the new thread is "fully created" only after we process both events, but I have noticed no regressions in treating it as "created" even after just processing the initial C event), but it is a source for many kinds of obscure races, since it introduces a new thread state "Launching" and the rest of the code does not handle this state at all (what happens if we get a resume request from LLDB while this thread is launching? what happens if we get a stop request? etc.). This fixes the "spurious $O packet" problem in TestPrintStackTraces.py. However, the test remains disabled on i386 due to the VDSO issue. Test Plan: TestPrintStackTraces works on x86_64. No regressions in the rest of the test suite. Reviewers: vharron, chaoren Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D9145 llvm-svn: 235579
