* Fix race in IOHandlerProcessSTDIOPavel Labath2015-05-281-74/+55
| | | | | | | | | | | | | | | | | | Summary: IOHandlerProcessSTDIO::Run() was opening the pipe for interrupt requests lazily. This was racing with another thread executing IOHandlerProcessSTDIO::Cancel() simultaneously. I fix this by opening the pipe in the object constructor. The pipe will be automatically closed when the object is destroyed. Test Plan: Tests pass on linux.

* [NativeProcessLinux] Support inferiors which change their process groupPavel Labath2015-05-281-7/+7
| | | | | | | | | | | | | | | | | | | | Summary: Previously, we wait()ed for events from the inferiors process group. This is resulted in a failure if the inferior changed its process group in the middle of execution. To avoid this, I pass -1 to the wait() call. The flag __WNOTHREAD makes sure we don't actually wait for events from any process, but only the processes(threads) which are our children (or traced by us). Since this happens on the monitor thread, which is dedicated to monitoring a single inferior, we will be getting events only from this inferior. Test Plan: All tests pass on linux. I have added a test to check the new functionality. Reviewers: chaoren, ovyalov Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D10061 llvm-svn: 238405
* Added a new API to SBFrame:Greg Clayton2015-05-281-0/+11
| | | | | | | | | | lldb::addr_t SBFrame::GetCFA(); This gets the CFA (call frame address) of the frame so it allows us to take an address that is on the stack and figure out which thread it comes from. Also modified the heap.py module to be able to find out which variable in a frame's stack frame contains an address. This way when ptr_refs finds a match on the stack, it get then report which variable contains the pointer. llvm-svn: 238393
* I finally found the strong reference that was keeping all ↵Greg Clayton2015-05-281-0/+7
| | | | | | | | | | | | lldb_private::Process instances from ever destroying themselves: ProcessModID.m_mod_id was holding onto the last stop event with ProcessModID::SetStopEventForLastNaturalStopID(EventSP). This is a bad idea because ProcessEventData contains a strong refereence to the process. This is now fixed by calling ProcessModID::SetStopEventForLastNaturalStopID(EventSP()) to clear this event in Process::SetExitStatus() and in Process::Finalize(). This was the original cause of the file descriptor leaks that would cause the test suite to die after running a few hundred processes since no process would ever get destroyed and the communication channel in ProcessGDBRemote and the ProcessIOHandler would never close their pipes. This process leak was previously worked around by closing the pipes when the communication channel was disconnected. This was found by using "ptr_refs" from the heap.py in the lldb.macosx.heap module. It was able to find all strong references to the Process and helped me to figure out who was holding this extra reference. llvm-svn: 238392
* Allow expresions to have unique expression prefixes:Greg Clayton2015-05-272-1/+27
| | | | | | | | | | | | | | | | | | expr_options = lldb.SBExpressionOptions() expr_options.SetPrefix(''' struct Foo { int a; int b; int c; } ''' expr_result = frame.EvaluateExpression ("Foo foo = { 1, 2, 3}; foo", expr_options) This fixed a current issue with ptr_refs, cstr_refs and malloc_info so that they can work. If expressions define their own types and then return expression results that use those types, those types get copied into the target's AST context so they persist and the expression results can be still printed and used in future expressions. Code was added to the expression parser to copy the context in which types are defined if they are used as the expression results. So in the case of types defined by expressions, they get defined in a lldb_expr function and that function and _all_ of its statements get copied. Many types of statements are not supported in this copy (array subscript, lambdas, etc) so this causes expressions to fail as they can't copy the result types. To work around this issue I have added code that allows expressions to specify an expression specific prefix. Then when you evaluate the expression you can pass the "expr_options" and have types that can be correctly copied out into the target. I added this as a way to work around an issue, but I also think it is nice to be allowed to specify an expression prefix that can be reused by many expressions, so this feature is very useful. <rdar://problem/21130675> llvm-svn: 238365

* Change ProcessGDBRemote last stop packet to a container.Ewan Crawford2015-05-274-18/+62
| | | | | | | | | | | | | | | In ProcessGDBRemote we currently have a single packet, m_last_stop_packet, used to set the thread stop info. However in non-stop mode we can receive several stop reply packets in a sequence for different threads. As a result we need to use a container to hold them before they are processed. This patch also changes the return type of CheckPacket() so we can detect async notification packets.

* Improve LLDB prompt handlingPavel Labath2015-05-278-292/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix we have in for this is not working all the time and is introducing unnecessary delays. This change does: - Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to lldb-dev. - coordinates printing of asynchronous text with the iohandlers. This is also based on a (different) Greg's patch, but I have added stronger synchronization to it to avoid races. Together, these changes solve the prompt problem for me on linux (both with and without libedit). I think they should behave similarly on Mac and FreeBSD and I think they will not make matters worse for windows. Test Plan: Prompt comes out alright. All tests still pass on linux.

* Parse function name from DWARF DW_AT_abstract_originTamas Berghammer2015-05-271-9/+13
| | | | | | | | | | | | | | | A DW_TAG_subprogram entry can contain a reference to a DW_AT_abstract_origin entry instead of duplicating the information from it (e.g.: name) when the same function is inlined in some case and not inlined in other cases. This CL fixes name parsing for the case when the DW_TAG_subprogram for the non inlined version contains just a reference to the DW_AT_abstract_origin entry instead of the full information.

* Add support for custom commands to set flags on themselvesEnrico Granata2015-05-2717-149/+238
| | | | | | | | | This works for Python commands defined via a class (implement get_flags on your class) and C++ plugin commands (which can call SBCommand::GetFlags()/SetFlags()) Flags allow features such as not letting the command run if there's no target, or if the process is not stopped, ...

* Added XML to the host layer.Greg Clayton2015-05-269-676/+1029
| | | | | | | | | | | | We know have on API we should use for all XML within LLDB in XML.h. This API will be easy back the XML parsing by different libraries in case libxml2 doesn't work on all platforms. It also allows the only place for #ifdef ...XML... to be in XML.h and XML.cpp. The API is designed so it will still compile with or without XML support and there is a static function "bool XMLDocument::XMLEnabled()" that can be called to see if XML is currently supported. All APIs will return errors, false, or nothing when XML isn't enabled. Converted all locations that used XML over to using the host XML implementation. Added target.xml support to debugserver. Extended the XML register format to work for LLDB by including extra attributes and elements where needed. This allows the target.xml to replace the qRegisterInfo packets and allows us to fetch all register info in a single packet. <rdar://problem/21090173> llvm-svn: 238224
* Move register reading form NativeProcessLinux to NativeRegisterContextLinux*Tamas Berghammer2015-05-2617-1592/+1461
| | | | | | | | | | | | | | | | | This change reorganize the register read/write code inside lldb-server on Linux with moving the architecture independent code into a new class called NativeRegisterContextLinux and all of the architecture dependent code into the appropriate NativeRegisterContextLinux_* class. As part of it the compilation of the architecture specific register contexts are only compiled on the specific architecture because they can't be used in other cases. The purpose of this change is to remove a lot of duplicated code from the different register contexts and to remove the architecture dependent codes from the global NativeProcessLinux class.

* Did some cleanup to stop us from leaking Pipe file descriptors.Greg Clayton2015-05-235-8/+39
| | | | | | | | | | The main issue was the Communication::Disconnect() was calling its Connection::Disconnect() but this wouldn't release the pipes that the ConnectionFileDescriptor was using. We also have someone that is holding a strong reference to the Process so that when you re-run, target replaces its m_process_sp, but it doesn't get destructed because someone has a strong reference to it. I need to track that down. But, even if we have a strong reference to the a process that is outstanding, we need to call Process::Finalize() to have it release as much of its resources as possible to avoid memory bloat. Removed the ProcessGDBRemote::SetExitStatus() override and replaced it with ProcessGDBRemote::DidExit(). Now we aren't leaking file descriptors and the stand alone test suite should run much better. llvm-svn: 238089

* [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.
