2013-05-17The Linux process plugin wasn't returning the correct linux signals. This ↵Matt Kopec
fixes that. Thus, this patch also negates a previous fix for handling SIGCHLD. llvm-svn: 182166
2013-05-17ProcessMonitor improvements for Linux.Matt Kopec
-Remove tracing of fork/vfork until we add support for tracing inferiors' children on Linux. -Add trace exec option for ptrace so that we don't receive legacy SIGTRAP signals on execve calls. -Add handling of SIGCHLD sent by kernel (for now, deliver the signal to the inferior). llvm-svn: 182153
2013-05-13Fix Linux warning about missing virtual destructor in Operation classesDaniel Malea
llvm-svn: 181712
2013-05-09Fixed "log enable linux registers" and added a test.Ashok Thirumurthi
- Eliminated the use of static for methods that read m_register_infos, so that these routines can be implemented in the base class. - Eliminated m_register_infos in the base class because this is not used when derived classes call UpdateRegisterInfo. - Also moved the namespace using declarations from headers to source files. Thanks to Daniel and Samuel for their review feedback. llvm-svn: 181538
2013-05-07Add watchpoint support for Linux on 64-bit host.Matt Kopec
llvm-svn: 181341
2013-04-18After discussing with Chris Lattner, we require C++11, so lets get rid of ↵Greg Clayton
the macros and just use C++11. llvm-svn: 179805
2013-04-18Since we use C++11, we should switch over to using std::unique_ptr when ↵Greg Clayton
C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++. Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro. llvm-svn: 179779
2013-03-28Fix the Linux build issues introduced by r178191.Ashok Thirumurthi
- All Linux logging channels now use a single global instance of lldb_private::Log, to handle the case of logging during process tear down. - Also removed a single use of LogSP in FreeBSD and fixed a typo in a comment while reading through ProcessKDPLog. Reviewed by Daniel Malea. llvm-svn: 178242

2012-11-23Fix Linux bug that leaves lldb in invalid state after expression evaluation ↵Daniel Malea
times out. - Handle EINVAL return code from ptrace(GETSIGINFO, ...): not an error, but 'group-stop' state on Linux - propagate SIGSTOP to inferior in above case - this commit resolves the failure in expression_command/timeout testcase Thanks to Sean Callanan & Matt Kopec for helping debug this problem llvm-svn: 168523
2012-11-22Remove call to StopMonitor() from ProcessMonitor::Detach()Daniel Malea
- StopMonitor() is called anyways from ProcessMonitor destructor later - resolves hang in TestEvents.py Patch by Matt Kopec! llvm-svn: 168503
2012-10-16Patch from Matt Kopec:Greg Clayton
This patch fixes an issue where if lldb fails to attach to a process (ie. invalid pid) on Linux, the process monitor thread gets stuck waiting for a signal from the attach thread, which never comes due to not being signaled. It also implements StopOpThread which is used for both attach/launch cases as I'm not aware of any special handling needed for the attach case. Also, propagate 'Error' from the Detach function instead of using a bool. llvm-svn: 166055

2012-10-12Modified patch from Matt Kopec that makes sure the run lock is acquired when ↵Greg Clayton
attaching and makes sure the pid is being set on linux in the process info. llvm-svn: 165804
2012-09-07Patch from Andrew Kaylor for linux:Greg Clayton
The attached patch adds support for debugging 32-bit processes when running a 64-bit lldb on an x86_64 Linux system. Making this work required two basic changes: 1) Getting lldb to report that it could debug 32-bit processes 2) Changing an assumption about how ptrace works when debugging cross-platform For the first change, I took a conservative approach and only enabled this for x86_64 Linux platforms. It may be that the change I made in Host.cpp could be extended to other 64-bit Linux platforms, but I'm not familiar enough with the other platforms to know for sure. For the second change, the Linux ProcessMonitor class was assuming that ptrace(PTRACE_[PEEK|POKE]DATA...) would read/write a "word" based on the child process word size. However, the ptrace documentation says that the "word" size read or written is "determined by the OS variant." I verified experimentally that when ptracing a 32-bit child from a 64-bit parent a 64-bit word is read or written. llvm-svn: 163398
