* 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
* Remove DoAttachToProcessWithId(lldb::pid_t).Zachary Turner2015-05-131-7/+0
| | | | | | | | | | There were two versions of DoAttachToprocessWithId. One that takes a pid_t, and the other which takes a pid_t and a ProcessAttachInfo. There were no callers of the former version, and all of the implementations of this version were simply forwarding calls to one version or the other. llvm-svn: 237281
* Remote Non-Stop SupportEwan Crawford2015-05-131-6/+56
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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

* Remove ScriptInterpreterObject.Zachary Turner2015-03-171-22/+25
| | | | | | | | | | | | | | | | | | | | | | | | | This removes ScriptInterpreterObject from the codebase completely. Places that used to rely on ScriptInterpreterObject now use StructuredData::Object and its derived classes. To support this, a new type of StructuredData object is introduced, called StructuredData::Generic, which stores a void*. Internally within the python library, StructuredPythonObject subclasses this StructuredData::Generic class so that it can addref and decref the python object on construction and destruction. Additionally, all of the classes in PythonDataObjects.h such as PythonList, PythonDictionary, etc now provide a method to create an instance of the corresponding StructuredData type. For example, there is PythonDictionary::CreateStructuredDictionary. To eliminate dependencies on PythonDataObjects for external callers, all ScriptInterpreter methods now return only StructuredData classes The rest of the changes in this CL are focused on fixing up users of PythonDataObjects classes to use the new StructuredData classes. llvm-svn: 232534

* llgs: fixes to PTY/gdb-remote inferior stdout/stderr handling, logging addtions.Todd Fiala2014-10-111-7/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, both local-process llgs and remote-target llgs stdout/stderr handling from inferior work correctly. Several log lines have been added around PTY and stdout/stderr redirection logic on the lldb client side. Regarding remote llgs execution, see the following: With these changes, remote llgs with $O now works properly: $ lldb (lldb) platform select remote-linux (lldb) target create ~/some/inferior/exe (lldb) gdb-remote {some-target}:{port} (lldb) run The sequence above will correctly redirect stdout/stderr over gdb-remote $O, as is needed for remote debugging. That sequence assumes there is a lldb-gdbserver exe running on the target with {some-host}:{port}. You can replace the gdb-remote command with a '(lldb) platform connect connect://{target-ip}:{target-port}'. If you do this and have a lldb-platform running on the remote end, it will go ahead and launch llgs for lldb for each target instance that is run/attached. For local debugging with llgs, the following sequence also works, and uses local PTYs instead to avoid $O and extra gdb-remote messages: $ lldb (lldb) settings set platform.plugin.linux.use-llgs true (lldb) target create ~/some/inferior/exe (lldb) run The above will run the inferior using llgs on the local host, and will use PTYs rather than $O redirection. This change also removes the logging that happened after the fork but before the exec when llgs is launching a new inferior process. Some aspect of the file handling during that portion of code would not do the right thing with log handling. We might want to go back later and have that communicate over a pipe from the child to parent to pass along any messages that previously were logged in that section of code. llvm-svn: 219578

| | | | | | | | | | | | | | | | See http://reviews.llvm.org/D5108 for details. This change does the following: * eliminates the Process::GetUnixSignals() virtual method and replaces with a fixed getter. * replaces the Process UnixSignals storage with a shared pointer. * adds a Process constructor variant that can be passed the UnixSignalsSP. When the constructor without the UnixSignalsSP is specified, the Host's default UnixSignals is used. * adds a host-specific version of GetUnixSignals() that is used when we need the host's appropriate UnixSignals variant. * replaces GetUnixSignals() overrides in PlatformElfCore, ProcessGDBRemote, ProcessFreeBSD and ProcessLinux with code that appropriately sets the Process::UnixSignals for the process. This change also enables some future patches that will enable llgs to be used for local Linux debugging. llvm-svn: 216748

| | | | | | | | | | | | | | | | | | | | | This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64. (More architectures coming soon). Not every debugserver option is covered yet.

The history of this large change can be found here: https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64 Until mid/late April, I was not sharing the work and continued to rebase it off of head (developed via id tfiala@google.com).
