* Rationalize how we do Halt-ing before Destroy and Detach.Jim Ingham2013-03-291-8/+3

* A little cleanup. {Disable/Enable}Breakpoint actually disables/enables ↵Jim Ingham2013-02-151-2/+2
| | | | | | | | | BreakpointSites not breakpoints, it is confusing to have it not named appropriately. Also in StopInfoMachException, we aren't testing for software or not software, just whether the thing is a breakpoint we set. So don't use "software"... llvm-svn: 175241

| | | | | | | | | | | | | | | | | | | | | | | | | | Enhance lldb so it can search for a kernel in memory when attaching to a remote system. Remove some of the code that was doing this from ProcessMachCore and ProcessGDBRemote and put it in DynamicLoaderDarwinKernel. I've added a new setting, plugin.dynamic-loader.darwin-kernel.scan-type which can be set to none - for environments where reading random memory can cause a device crash basic - look at one fixed location in memory for a kernel load address, plus the contents of that address fast-scan - the default, tries "basic" and then looks for the kernel's mach header near the current pc value when lldb connects exhaustive-scan - on 32-bit targets, step through the entire range where the kernel can be loaded, looking for the kernel binary I don't have the setting set up correctly right now, I'm getting back unexpected values from the Property system, but I'll figure that out tomorrow and fix. Besides that, all of the different communication methods / types of kernels appear to be working correctly with these changes. llvm-svn: 173891
* Adding events when watchpoints are set or changed.Jim Ingham2012-12-181-2/+2

* <rdar://problem/12649160>Greg Clayton2012-12-051-0/+3
| | | | | | Added the ability to debug through your process exec'ing itself to the same architecture. llvm-svn: 169340
* There seems to be some odd corner case where we shut down the ↵Jim Ingham2012-11-011-0/+9
| | | | | | | | ProcessGDBRemote, but we haven't managed to shut down the async thread. That causes the ProcessGDBRemote::AsyncThread to crash when it wakes up. So I changed StartAsyncThread and StopAsyncThread to be callable multiple times (only the first one does anything) so that we can just shut it down unequivocally in the ProcessGDBRemote destructor. <rdar://problem/12602981> llvm-svn: 167197
* <rdar://problem/12491387>Greg Clayton2012-10-131-2/+3
| | | | | | | | | | | I added the ability for a process plug-in to implement custom commands. All the lldb_private::Process plug-in has to do is override: virtual CommandObject * GetPluginCommandObject(); This object returned should be a multi-word command that vends LLDB commands. There is a sample implementation in ProcessGDBRemote that is hollowed out. It is intended to be used for sending a custom packet, though the body of the command execute function has yet to be implemented! llvm-svn: 165861
* The kernel loading code is now isolated in the DynamicLoaderDarwinKernel;Jason Molenda2012-10-031-4/+6
| | | | | | | | | | remove the duplicates of this code in ProcessGDBRemote and ProcessKDP. These two Process plugins will hardcode their DynamicLoader name to be the DynamicLoaderDarwinKernel so the correct DynamicLoader is picked, and return the kernel load address as the ImageInfosAddress. <rdar://problem/12417038> llvm-svn: 165080
* Add the RelocateOrLoadKernel and LoadKernel methods to ↵Jason Molenda2012-09-291-0/+7
| | | | | | | | | | | | | | ProcessGDBRemote::DoRemoteConnect(). When attaching to a remote system that does not look like a typical vendor system, and no executable binary was specified to lldb, check a couple of fixed locations where kernels running in ASLR mode (slid in memory to a random address) store their load addr when booted in debug mode, and relocate the symbols or load the kernel wholesale from the host computer if we can find it. <rdar://problem/7714201> llvm-svn: 164888
* Add support for debugging KASLR kernels via kdp (the kernel beingJason Molenda2012-09-291-1/+1
| | | | | | | | | | | | | | | | | | loaded at a random offset). To get the kernel's UUID and load address I need to send a kdp packet so I had to implement the kernel relocation (and attempt to find the kernel if none was provided to lldb already) in ProcessKDP -- but this code really properly belongs in DynamicLoaderDarwinKernel. I also had to add an optional Stream to ConnectRemote so ProcessKDP::DoConnectRemote can print feedback about the remote kernel's UUID, load address, and notify the user if we auto-loaded the kernel via the UUID. <rdar://problem/7714201> llvm-svn: 164881
* <rdar://problem/11782789> Changes to the watchpoint implementation on ARM so ↵Enrico Granata2012-07-131-0/+3
| | | | | | that we single-step before stopping at the WP. This is necessary because on ARM the WP triggers before the opcode is actually executed, so we would be unable to continue since we would keep hitting the WP. We work around this by disabling the WP, single stepping and then putting the WP back in place. llvm-svn: 160199
* Work around some problems destroying a process with older debugservers.Jim Ingham2012-07-041-0/+1
| | | | | | rdar://problem/11359989 llvm-svn: 159697
* Add the capability to display the number of supported hardware watchpoints ↵Johnny Chen2012-05-231-0/+3
| | | | | | | | | to the "watchpoint list" command. Add default Process::GetWatchpointSupportInfo() impl which returns an error of "not supported". Add "qWatchpointSupportInfo" packet to the gdb communication layer to support this, and modify TestWatchpointCommands.py to test it. llvm-svn: 157345

| | | | | | Correctly unique a class' methods when we detect that a class has been uniqued to another. llvm-svn: 156795
* <rdar://problem/11241798>Greg Clayton2012-04-131-1/+0
| | | | | | The less locks there are, the better. I removed the thread ID mutex and now just shared the m_thread_list's mutex to make sure we don't deadlock due to lock inversion. llvm-svn: 154652
* Make sure that DoResume doesn't stall if we shut down the async thread while ↵Jim Ingham2012-04-121-1/+2
| | | | | | | | | | | | | DoResume is waiting for packet confirmation. Also added a bit more logging. Also, unlock the writer end of the run lock in Process.cpp on our way out of the private state thread so that the Process can shut down cleanly. <rdar://problem/11228538> llvm-svn: 154601
* A general stability fix where we _always_ get the thread list immediately ↵Greg Clayton2012-04-101-0/+8
| | | | | | | | after we get the stop packets. We had some racy conditions where thread 1 might be sending a packet and thread 2 tries to send a packet to get the thread list and it fails and ends up with an empty list. Packets use a sequence mutex to be able to ensure when you send a packet, you get the resonse. This sequence mutex is take when the process is running, and as we exit the running state and notify our process with the stop packet, we now always get the thread ID list before we do anything and before we can run into race conditions. The next step is to have our stop reply packets send the thread list in the actual stop reply packet to avoid a 2 packet overhead of sending the qfThreadInfo + response and qfThreadInfo + response. llvm-svn: 154376
* Trying to solve our disappearing thread issues by making thread list updates ↵Greg Clayton2012-04-101-1/+1
| | | | | | | | | | | | | | | | safer. The current ProcessGDBRemote function that updates the threads could end up with an empty list if any other thread had the sequence mutex. We now don't clear the thread list when we can't access it, and we also have changed how lldb_private::Process handles the return code from the: virtual bool Process::UpdateThreadList (lldb_private::ThreadList &old_thread_list, lldb_private::ThreadList &new_thread_list) = 0; A bool is now returned to indicate if the list was actually updated or not and the lldb_private::Process class will only update the stop ID of the validity of the thread list if "true" is returned. The ProcessGDBRemote also got an extra assertion that will hopefully assert when running debug builds so we can find the source of this issue. llvm-svn: 154365
* Added a packet history object to the GDBRemoteCommunication class that is ↵Greg Clayton2012-04-091-6/+6
| | | | | | always remembering the last 512 packets that were sent/received. These packets get dumped if logging gets enabled, or when the new expr lldb::DumpProcessGDBRemotePacketHistory (void *process, const char *log_file_path) global function is called. llvm-svn: 154354
* <rdar://problem/3535148>Han Ming Ong2012-02-251-1/+9
| | | | | | Added ability to debug root processes on OS X. This uses XPC service that is available on Lion and above only. llvm-svn: 151419
* First pass at mach-o core file support is in. It currently works for x86_64 Greg Clayton2012-02-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | user space programs. The core file support is implemented by making a process plug-in that will dress up the threads and stack frames by using the core file memory. Added many default implementations for the lldb_private::Process functions so that plug-ins like the ProcessMachCore don't need to override many many functions only to have to return an error. Added new virtual functions to the ObjectFile class for extracting the frozen thread states that might be stored in object files. The default implementations return no thread information, but any platforms that support core files that contain frozen thread states (like mach-o) can make a module using the core file and then extract the information. The object files can enumerate the threads and also provide the register state for each thread. Since each object file knows how the thread registers are stored, they are responsible for creating a suitable register context that can be used by the core file threads. Changed the process CreateInstace callbacks to return a shared pointer and to also take an "const FileSpec *core_file" parameter to allow for core file support. This will also allow for lldb_private::Process subclasses to be made that could load crash logs. This should be possible on darwin where the crash logs contain all of the stack frames for all of the threads, yet the crash logs only contain the registers for the crashed thrad. It should also allow some variables to be viewed for the thread that crashed. llvm-svn: 150154
* <rdar://problem/10487848>Greg Clayton2011-12-061-0/+7
| | | | | | Protect a member variable from being modified by multiple threads. llvm-svn: 145920
* Added optional calls to lldb_private::Process for getting memory region infoGreg Clayton2011-11-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | from a process and hooked it up to the new packet that was recently added to our GDB remote executable named debugserver. Now Process has the following new calls: virtual Error Process::GetMemoryRegionInfo (lldb::addr_t load_addr, MemoryRegionInfo &range_info); virtual uint32_t GetLoadAddressPermissions (lldb::addr_t load_addr); Only the first one needs to be implemented by subclasses that can add this support. Cleaned up the way the new packet was implemented in debugserver to be more useful as an API inside debugserver. Also found an error where finding a region for an address actually will pick up the next region that follows the address in the query so we also need ot make sure that the address we requested the region for falls into the region that gets returned. llvm-svn: 144976
* Made the darwin host layer properly reap any child processes that it spawns.Greg Clayton2011-11-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | After recent changes we weren't reaping child processes resulting in many zombie processes. This was fixed by adding more settings to the ProcessLaunchOptions class that allow clients to specify a callback function and baton to be notified when their process dies. If one is not supplied a default callback will be used that "does the right thing". Cleaned up a race condition in the ProcessGDBRemote class that would attempt to monitor when debugserver died. Added an extra boolean to the process monitor callbacks that indicate if a process exited or not. If your process exited with a zero exit status and no signal, both items could be zero. Modified the process monitor functions to not require a callback function in order to reap the child process. llvm-svn: 144780
* <rdar://problem/10103980>Greg Clayton2011-11-131-13/+0
| | | | | | | A long time ago we started to centralized the STDOUT in lldb_private::Process but we missed a few things still in ProcessGDBRemote. llvm-svn: 144491
* Modified all Process::Launch() calls to use a ProcessLaunchInfo structureGreg Clayton2011-11-031-8/+2
| | | | | | | | on internal only (public API hasn't changed) to simplify the paramter list to the launch calls down into just one argument. Also all of the argument, envronment and stdio things are now handled in a much more centralized fashion. llvm-svn: 143656
* SBValue::Watch() and SBValue::WatchPointee() are now the official API for ↵Johnny Chen2011-10-141-2/+2
| | | | | | | | | | | | | | | | | | creating a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee encapsulated by SBValue (WatchPointee). Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that. Modified the watchpoint related test suite to reflect the change. Plus replacing WatchpointLocation with Watchpoint throughout the code base. There are still cleanups to be dome. This patch passes the whole test suite. Check it in so that we aggressively catch regressions. llvm-svn: 141925
* Added a new plug-in type: lldb_private::OperatingSystem. The operating system Greg Clayton2011-08-221-1/+2
| | | | | | | | | | | | | | | | | | | | plug-ins are add on plug-ins for the lldb_private::Process class that can add thread contexts that are read from memory. It is common in kernels to have a lot of threads that are not currently executing on any cores (JTAG debugging also follows this sort of thing) and are context switched out whose state is stored in memory data structures. Clients can now subclass the OperatingSystem plug-ins and then make sure their Create functions correcltly only enable themselves when the right binary/target triple are being debugged. The operating system plug-ins get a chance to attach themselves to processes just after launching or attaching and are given a lldb_private::Process object pointer which can be inspected to see if the main executable, target triple, or any shared libraries match a case where the OS plug-in should be used. Currently the OS plug-ins can create new threads, define the register contexts for these threads (which can all be different if desired), and populate and manage the thread info (stop reason, registers in the register context) as the debug session goes on. llvm-svn: 138228
* Added a boolean to the pure virtual lldb_private::Process::CanDebug(...)Greg Clayton2011-07-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | method so process plug-ins that are requested by name can answer yes when asked if they can debug a target that might not have any file in the target. Modified the ConnectionFileDescriptor to have both a read and a write file descriptor. This allows us to support UDP, and eventually will allow us to support pipes. The ConnectionFileDescriptor class also has a file descriptor type for each of the read and write file decriptors so we can use the correct read/recv/recvfrom call when reading, or write/send/sendto for writing. Finished up an initial implementation of UDP where you can use the "udp://" URL to specify a host and port to connect to: (lldb) process connect --plugin kdp-remote udp://host:41139 This will cause a ConnectionFileDescriptor to be created that can send UDP packets to "host:41139", and it will also bind to a localhost port that can be given out to receive the connectionless UDP reply. Added the ability to get to the IPv4/IPv6 socket port number from a ConnectionFileDescriptor instance if either file descriptor is a socket. The ProcessKDP can now successfully connect to a remote kernel and detach using the above "processs connect" command!!! So far we have the following packets working: KDP_CONNECT KDP_DISCONNECT KDP_HOSTINFO KDP_VERSION KDP_REATTACH Now that the packets are working, adding new packets will go very quickly. llvm-svn: 135363
* Removed an member variable "m_local_debugserver" that is no longer needed.Greg Clayton2011-06-241-1/+0
| | | | | | | We now check with the platform to see if we are doing local or remote debugging and setup the stdio accordingly. llvm-svn: 133835
* Make sure we don't lose our stop reply packet in the case where the otherGreg Clayton2011-06-021-1/+1
| | | | | | GDB server doesn't support the LLDB specific qThreadStopInfo packet. llvm-svn: 132499
* Added the ability to get the return value from a ThreadPlanCallFunctionGreg Clayton2011-05-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thread plan. In order to get the return value, you can call: void ThreadPlanCallFunction::RequestReturnValue (lldb::ValueSP &return_value_sp); This registers a shared pointer to a return value that will get filled in if everything goes well. After the thread plan is run the return value will be extracted for you. Added an ifdef to be able to switch between the LLVM MCJIT and the standand JIT. We currently have the standard JIT selected because we have some work to do to get the MCJIT fuctioning properly. Added the ability to call functions with 6 argument in the x86_64 ABI. Added the ability for GDBRemoteCommunicationClient to detect if the allocate and deallocate memory packets are supported and to not call allocate memory ("_M") or deallocate ("_m") if we find they aren't supported. Modified the ProcessGDBRemote::DoAllocateMemory(...) and ProcessGDBRemote::DoDeallocateMemory(...) to be able to deal with the allocate and deallocate memory packets not being supported. If they are not supported, ProcessGDBRemote will switch to calling "mmap" and "munmap" to allocate and deallocate memory instead using our trivial function call support. Modified the "void ProcessGDBRemote::DidLaunchOrAttach()" to correctly ignore the qHostInfo triple information if any was specified in the target. Currently if the target only specifies an architecture when creating the target: (lldb) target create --arch i386 a.out Then the vendor, os and environemnt will be adopted by the target. If the target was created with any triple that specifies more than the arch: (lldb) target create --arch i386-unknown-unknown a.out Then the target will maintain its triple and not adopt any new values. This can be used to help force bare board debugging where the dynamic loader for static files will get used and users can then use "target modules load ..." to set addressses for any files that are desired. Added back some convenience functions to the lldb_private::RegisterContext class for writing registers with unsigned values. Also made all RegisterContext constructors explicit to make sure we know when an integer is being converted to a RegisterValue. llvm-svn: 131370
* Moved the execution context that was in the Debugger intoGreg Clayton2011-04-121-21/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the CommandInterpreter where it was always being used. Make sure that Modules can track their object file offsets correctly to allow opening of sub object files (like the "__commpage" on darwin). Modified the Platforms to be able to launch processes. The first part of this move is the platform soon will become the entity that launches your program and when it does, it uses a new ProcessLaunchInfo class which encapsulates all process launching settings. This simplifies the internal APIs needed for launching. I want to slowly phase out process launching from the process classes, so for now we can still launch just as we used to, but eventually the platform is the object that should do the launching. Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able to launch processes with all of the new eLaunchFlag settings. Modified any code that was manually launching processes to use the Host::LaunchProcess functions. Fixed an issue where lldb_private::Args had implicitly defined copy constructors that could do the wrong thing. This has now been fixed by adding an appropriate copy constructor and assignment operator. Make sure we don't add empty ModuleSP entries to a module list. Fixed the commpage module creation on MacOSX, but we still need to train the MacOSX dynamic loader to not get rid of it when it doesn't have an entry in the all image infos. Abstracted many more calls from in ProcessGDBRemote down into the GDBRemoteCommunicationClient subclass to make the classes cleaner and more efficient. Fixed the default iOS ARM register context to be correct and also added support for targets that don't support the qThreadStopInfo packet by selecting the current thread (only if needed) and then sending a stop reply packet. Debugserver can now start up with a --unix-socket (-u for short) and can then bind to port zero and send the port it bound to to a listening process on the other end. This allows the GDB remote platform to spawn new GDB server instances (debugserver) to allow platform debugging. llvm-svn: 129351
* Split the GDBRemoteCommunication class into three classes:Greg Clayton2011-03-221-4/+4
| | | | | | | | | | GDBRemoteCommunication - The base GDB remote communication class GDBRemoteCommunicationClient - designed to be used for clients the connect to a remote GDB server GDBRemoteCommunicationServer - designed to be used on the server side of a GDB server implementation. llvm-svn: 128070
* Added more platform support. There are now some new commands:Greg Clayton2011-03-191-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platform status -- gets status information for the selected platform platform create <platform-name> -- creates a new instance of a remote platform platform list -- list all available platforms platform select -- select a platform instance as the current platform (not working yet) When using "platform create" it will create a remote platform and make it the selected platform. For instances for iPhone OS debugging on Mac OS X one can do: (lldb) platform create remote-ios --sdk-version=4.0 Remote platform: iOS platform SDK version: 4.0 SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0" Not connected to a remote device. (lldb) file ~/Documents/a.out Current executable set to '~/Documents/a.out' (armv6). (lldb) image list [ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out [ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld [ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib Note that this is all happening prior to running _or_ connecting to a remote platform. Once connected to a remote platform the OS version might change which means we will need to update our dependecies. Also once we run, we will need to match up the actualy binaries with the actualy UUID's to files in the SDK, or download and cache them locally. This is just the start of the remote platforms, but this modification is the first iteration in getting the platforms really doing something. llvm-svn: 127934
* Centralize the GDB remote timeout value into the GDBRemoteCommunication as aGreg Clayton2011-03-101-1/+0
| | | | | | | member variable (m_packet_timeout which is a value in seconds). This value is then used for all packets sent to/from the remote GDB server. llvm-svn: 127392
* LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provideGreg Clayton2011-03-081-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an interface to a local or remote debugging platform. By default each host OS that supports LLDB should be registering a "default" platform that will be used unless a new platform is selected. Platforms are responsible for things such as: - getting process information by name or by processs ID - finding platform files. This is useful for remote debugging where there is an SDK with files that might already or need to be cached for debug access. - getting a list of platform supported architectures in the exact order they should be selected. This helps the native x86 platform on MacOSX select the correct x86_64/i386 slice from universal binaries. - Connect to remote platforms for remote debugging - Resolving an executable including finding an executable inside platform specific bundles (macosx uses .app bundles that contain files) and also selecting the appropriate slice of universal files for a given platform. So by default there is always a local platform, but remote platforms can be connected to. I will soon be adding a new "platform" command that will support the following commands: (lldb) platform connect --name machine1 macosx connect://host:port Connected to "machine1" platform. (lldb) platform disconnect macosx This allows LLDB to be well setup to do remote debugging and also once connected process listing and finding for things like: (lldb) process attach --name x<TAB> The currently selected platform plug-in can now auto complete any available processes that start with "x". The responsibilities for the platform plug-in will soon grow and expand. llvm-svn: 127286
* Fixed CommandReturnObject::SetImmediateErrorFile() to set the correct stream.Greg Clayton2011-02-241-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Modifed lldb_private::Process to be able to handle connecting to a remote target that isn't running a process. This leaves lldb_private::Process in the eStateConnected state from which we can then do an attach or launch. Modified ProcessGDBRemote to be able to set stdin, stdout, stderr, working dir, disable ASLR and a few other settings down by using new GDB remote packets. This allows us to keep all of our current launch flags and settings intact and still be able to communicate them over to the remote GDB server. Previously these were being sent as arguments to the debugserver binary that we were spawning. Also modified ProcessGDBRemote to handle losing connection to the remote GDB server and always exit immediately. We do this by watching the lldb_private::Communication event bit for the read thread exiting in the ProcessGDBRemote async thread. Added support for many of the new 'Q' packets for setting stdin, stdout, stderr, working dir and disable ASLR to the GDBRemoteCommunication class for easy accesss. Modified debugserver for all of the new 'Q' packets and also made it so that debugserver always exists if it loses connection with the remote debugger. llvm-svn: 126444
* The DynamicLoader plug-in instance now lives up in lldb_private::Process whereGreg Clayton2011-02-161-5/+0
| | | | | | | | | | | | | | | | | it should live and the lldb_private::Process takes care of managing the auto pointer to the dynamic loader instance. Also, now that the ArchSpec contains the target triple, we are able to correctly set the Target architecture in DidLaunch/DidAttach in the subclasses, and then the lldb_private::Process will find the dynamic loader plug-in by letting the dynamic loader plug-ins inspect the arch/triple in the target. So now the ProcessGDBRemote plug-in is another step closer to be purely process/platform agnostic. I updated the ProcessMacOSX and the ProcessLinux plug-ins accordingly. llvm-svn: 125650
* Added the ability to detect which vCont packets (using the "vCont?") packetGreg Clayton2011-02-121-1/+7
| | | | | | | | | are supported by the remote GDB target. We can also now deal with the lack of vCont support and send packets that the remote GDB stub can use. We also error out of the continue if LLDB tries to do something too complex when vCont isn't supported. llvm-svn: 125433
* Added support for attaching to a remote debug server with the new command:Greg Clayton2011-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (lldb) process connect <remote-url> Currently when you specify a file with the file command it helps us to find a process plug-in that is suitable for debugging. If you specify a file you can rely upon this to find the correct debugger plug-in: % lldb a.out Current executable set to 'a.out' (x86_64). (lldb) process connect connect://localhost:2345 ... If you don't specify a file, you will need to specify the plug-in name that you wish to use: % lldb (lldb) process connect --plugin process.gdb-remote connect://localhost:2345 Other connection URL examples: (lldb) process connect connect://localhost:2345 (lldb) process connect tcp://127.0.0.1 (lldb) process connect file:///dev/ttyS1 We are currently treating the "connect://host:port" as a way to do raw socket connections. If there is a URL for this already, please let me know and we will adopt it. So now you can connect to a remote debug server with the ProcessGDBRemote plug-in. After connection, it will ask for the pid info using the "qC" packet and if it responds with a valid process ID, it will be equivalent to attaching. If it response with an error or invalid process ID, the LLDB process will be in a new state: eStateConnected. This allows us to then download a program or specify the program to run (using the 'A' packet), or specify a process to attach to (using the "vAttach" packets), or query info about the processes that might be available. llvm-svn: 124846

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | takes separate file handles for stdin, stdout, and stder and also allows for the working directory to be specified. Added support to "process launch" to a new option: --working-dir=PATH. We can now set the working directory. If this is not set, it defaults to that of the process that has LLDB loaded. Added the working directory to the host LaunchInNewTerminal function to allows the current working directory to be set in processes that are spawned in their own terminal. Also hooked this up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its API changed, but nothing is making use of it yet. Modfied "debugserver" and "darwin-debug" to also handle the current working directory options and modified the code in LLDB that spawns these tools to pass the info along. Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout and stderr. After clearing the default values for the stdin/out/err file handles for process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable which is now fixed. Also fixed the setting of boolean values to be able to be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no", "off", or "0" for false. Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not already opened. Previous to this fix debugserver would only correctly open and dupe file handles for the slave side of a pseudo terminal. It now correctly handles getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to files. Also made sure the file handles were correctly opened with the NOCTTY flag for terminals. llvm-svn: 124060

Fixed the GDB remote plug-in to once again watch for a reply from the "k" packet, and fixed the logic to make sure the thread requesting the kill and the async thread play nice (and very quickly) by synchronizing the packet sending and reply. I also tweaked some of the shut down packet ("k" kill, "D" detach, and the halt packet) to make sure they do the right thing. Fixed "StateType Process::WaitForProcessStopPrivate (...)" to correctly pass the timeout along to WaitForStateChangedEventsPrivate() and made the function behave correctly with respect to timing out. Added separate STDIN, STDOUT, and STDERR support to debugserver. Also added the start of being able to set the working directory for the inferior process. llvm-svn: 124049

Also add a user settings variable, 'target.process.disable-stdio' to allow the user to set this globally rather than having to use the command option each time the process is launched. llvm-svn: 120825
* Fixed Process::Halt() as it was broken for "process halt" after recent changesGreg Clayton2010-11-181-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | to the DoHalt down in ProcessGDBRemote. I also moved the functionality that was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has to implement a tricky halt/resume on the internal state thread. The functionality is the same as it was before with two changes: - when we eat the event we now just reuse the event we consume when the private state thread is paused and set the interrupted bool on the event if needed - we also properly update the Process::m_public_state with the state of the event we consume. Prior to this, if you issued a "process halt" it would eat the event, not update the process state, and then produce a new event with the interrupted bit set and send it. Anyone listening to the event would get the stopped event with a process that whose state was set to "running". Fixed debugserver to not have to be spawned with the architecture of the inferior process. This worked fine for launching processes, but when attaching to processes by name or pid without a file in lldb, it would fail. Now debugserver can support multiple architectures for a native debug session on the current host. This currently means i386 and x86_64 are supported in the same binary and a x86_64 debugserver can attach to a i386 executable. This change involved a lot of changes to make sure we dynamically detect the correct registers for the inferior process. llvm-svn: 119680
* Added an "Interrupted" bit to the ProcessEventData. Halt now generates an eventJim Ingham2010-11-171-1/+1

DoHalt is changed to ensure that the stop even is processed, and an event with the Interrupted event is posted. Finally ClangFunction is rationalized to use this facility so the that Halt is handled more deterministically. llvm-svn: 119453
