Todd Fiala f3d61de532 Enable Linux distribution in vendor portion of host triple.
This change does the following:

* enables building lldb-gdbserver on linux_x86-64 platforms.

  Note - it builds but it has several run-time issues where many gdb
  remote protocol features are not properly implemented yet. I'm
  working on these one at a time.

* lldb-gdbserver: does not enable the eLaunchFlagDebug launch flag on
  Linux. Currently the POSIX launch routine will assert if that flag
  is passed in, presumably because that launch mode is not yet
  available.  This prevents lldb-gdbserver from asserting the moment
  it launches the debuggee process.

* Adds ConstString& Host::GetDistributionId ()

  This method is defined to return an empty result on all platforms
  except for Linux.  On Linux, it makes one attempt to execute
  'lsb_release -i' (both /usr/bin/lsb_release, where it appears
  on ubuntu, and /bin/lsb_release, where it appears on fedora
  if the redhat-lsb package is installed).  If lsb_release is not
  found in either of those locations, or if 'lsb_release -i' does
  not return the first line starting with "Distributor ID:\t",
  then the distribution id is empty.  The method will lower-case
  the id and replace whitespace with underscores.

* Modify Host::GetArchitecture () so that linux replaces an unknown
  vendor portion with the results of GetDistributionId () if that
  is non-empty.  This shows up now in qHostInfo remote packet
  responses and on the lldb host side.  Tested with ubuntu and
  fedora (the latter both with the default of not having lsb_release
  installed, and with having lsb_release installed via the redhat-lsb
  package).

  Examples of triples on Linux after this change:

    # x86_64 Unbuntu 12.04 LTS:
    x86_64-ubuntu-linux-gnu

    # x86_64 Fedora 20 Desktop with redhat-lsb package installed
    x86_64-fedora-linux-gnu

    # x86_64 Fedora 20 Desktop without redhat-lsb-core installed
    # (i.e. no /bin/lsb_release available)
    # same as before the change
    x86_64--linux-gnu

  Note I intend to have Android respond with:

    {arch}-android-linux

  when I get to implementing Android lldb-gdbserver support.

Greg Clayton fb90931b60 Improved platform support.
Improved the detection of a valid GDB server where we actually can connect to a socket, but then it doesn't read or write anything (which happens with some USB mux software).

Host::MakeDirectory() now can make as many intermediate directories as needed.

The testsuite now has very initial support for remote test suite running. When running on a remote platform, the setUp function for the test will make a new directory and select it as the working directory on the remote host. 

Added a common function that can be used to create the short option string for getopt_long calls.

Greg Clayton fbb7634934 Expose SBPlatform through the public API.
Example code:

remote_platform = lldb.SBPlatform("remote-macosx"); 
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)

connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111"); 
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
    print >> result, 'Connected to remote platform:'
    print >> result, 'hostname: %s' % (remote_platform.GetHostname())
    src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
    dst = lldb.SBFileSpec()
    # copy src to platform working directory since "dst" is empty
    err = remote_platform.Install(src, dst);
    if err.Success():
        print >> result, '%s installed successfully' % (src)
    else:
        print >> result, 'error: failed to install "%s": %s' % (src, err)


Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.

The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.

The API in SBPlatform is subject to change and will be getting many new functions.

Jim Ingham df0ae22f92 Changing the default shell to /bin/sh brought up a long-standing bug on OS X,
that /bin/sh re-exec's itself to /bin/bash, so it needs one more resume when you
are using it as the shell than /bin/bash did or you will stop at the start of your
program, rather than running it.

So I added a Platform API to get the number of resumes needed when launching with
a particular shell, and set the right values for Mac OS X.

Daniel Malea e0f8f574c7 merge lldb-platform-work branch (and assorted fixes) into trunk
Summary:
    This merge brings in the improved 'platform' command that knows how to
    interface with remote machines; that is, query OS/kernel information, push
    and pull files, run shell commands, etc... and implementation for the new
    communication packets that back that interface, at least on Darwin based
    operating systems via the POSIXPlatform class. Linux support is coming soon.

    Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
    X Mountain Lion.

    Additional improvements (not in the source SVN branch 'lldb-platform-work'):
    - cmake build scripts for lldb-platform
    - cleanup test suite
    - documentation stub for qPlatform_RunCommand
    - use log class instead of printf() directly
    - reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
    - add new logging category 'platform'

Sylvestre Ledru 594058394e Following the modification introduced in llvm by commit 185311
The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct. 

As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.

The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.

Fixes bug #16446.

llvm-svn: 179805
2013-04-18 22:45:39 +00:00
Greg Clayton e01e07b6e7 Since we use C++11, we should switch over to using std::unique_ptr when 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.

Greg Clayton 5160ce5c72 <rdar://problem/13521159>
LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

<rdar://problem/12068650>

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

Greg Clayton 453925530d <rdar://problem/12462048>
LLDB changes argv[0] when debugging a symlink. Now we have the notion of argv0 in the target settings:

target.arg0 (string) = 

There is also the program argument that are separate from the first argument that have existed for a while:

target.run-args (arguments) =

When running "target create <exe>", we will place the untouched "<exe>" into target.arg0 to ensure when we run, we run with what the user typed. This has been added to the ProcessLaunchInfo and all other needed places so we always carry around the:
- resolved executable path
- argv0
- program args

Some systems may not support separating argv0 from the resolved executable path and the ProcessLaunchInfo needs to carry all of this information along so that each platform can make that decision.

Greg Clayton 542e407581 Patch from Andrew Kaylor for linux:
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.

Greg Clayton 1a362fbb86 <rdar://problem/11439169>
"lldb -a i386" doesn't set the calculator mode correctly if run on a 64 bit system. 

The previous logic always used the current host architecture, not the default architecture. The default arch gets set into a static varaible in lldb_private::Target when an arch is set from the command line:

lldb -a i386

We now use the default arch correctly.

Jim Ingham c075ecd833 Fix a think in Mutex::Locker::Locker(pthread_mutex_t *) Really should lock the mutex handed in, not the m_mutex_ptr that you've set to NULL...
Rework the Host.cpp::ThreadNameAccessor to use ThreadSafeSTLMap - we've got it so we might as well use it.  Also works around a problem with the
Mutex::Locker class raising fallacious asserts in debug mode when used with pthread_mutex_t's that weren't backed by Mutex objects.

2012-05-04 19:24:49 +00:00
Greg Clayton d1cf11a74d Added a new host function that allows us to run shell command and get the output from them along with the status and signal:
Error
Host::RunShellCommand (const char *command,
                       const char *working_dir,
                       int *status_ptr,
                       int *signo_ptr,
                       std::string *command_output_ptr,
                       uint32_t timeout_sec);

This will allow us to use this functionality in the host lldb_private::Platform, and also use it in our lldb-platform binary. It leverages the existing code in Host::LaunchProcess and ProcessLaunchInfo.

Jim Ingham 372787fc19 We sometimes need to be able to call functions (via Process::RunThreadPlan) from code run on the private state thread. To do that we have to
spin up a temporary "private state thread" that will respond to events from the lower level process plugins.  This check-in should work to do
that, but it is still buggy.  However, if you don't call functions on the private state thread, these changes make no difference.

This patch also moves the code in the AppleObjCRuntime step-through-trampoline handler that might call functions (in the case where the debug
server doesn't support the memory allocate/deallocate packet) out to a safe place to do that call.

Greg Clayton c859e2d524 Full core file support has been added for mach-o core files.
Tracking modules down when you have a UUID and a path has been improved.

DynamicLoaderDarwinKernel no longer parses mach-o load commands and it
now uses the memory based modules now that we can load modules from memory.

Added a target setting named "target.exec-search-paths" which can be used
to supply a list of directories to use when trying to look for executables.
This allows one or more directories to be used when searching for modules
that may not exist in the SDK/PDK. The target automatically adds the directory
for the main executable to this list so this should help us in tracking down
shared libraries and other binaries.

2012-02-13 23:10:39 +00:00
Greg Clayton e38a5edd9e Added code in the Host layer that can report system log messages
so that we don't have "fprintf (stderr, ...)" calls sprinkled everywhere.
Changed all needed locations over to using this.

For non-darwin, we log to stderr only. On darwin, we log to stderr _and_
to ASL (Apple System Log facility). This will allow GUI apps to have a place
for these error and warning messages to go, and also allows the command line
apps to log directly to the terminal.

2011-11-17 19:41:57 +00:00
Greg Clayton e4e45924d7 Made the darwin host layer properly reap any child processes that it spawns.
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.

2011-11-04 03:42:38 +00:00
Greg Clayton dce502ede0 Fixed the Xcode project building of LLVM to be a bit more user friendly:
- If you download and build the sources in the Xcode project, x86_64 builds
  by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
  Xcode project will download the right LLVM sources and build them from 
  scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
  directory, we will use the sources you have placed in the LLDB directory.
  
Python can now be disabled for platforms that don't support it. 

Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.

llvm-svn: 131303
2011-05-13 19:57:45 +00:00
Greg Clayton 8b82f087a0 Moved the execution context that was in the Debugger into
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: 129130
2011-04-08 13:36:44 +00:00
Greg Clayton 32e0a7509c Many improvements to the Platform base class and subclasses. The base Platform
class now implements the Host functionality for a lot of things that make 
sense by default so that subclasses can check:

int
PlatformSubclass::Foo ()
{
    if (IsHost())
        return Platform::Foo (); // Let the platform base class do the host specific stuff
    
    // Platform subclass specific code...
    int result = ...
    return result;
}

Added new functions to the platform:

    virtual const char *Platform::GetUserName (uint32_t uid);
    virtual const char *Platform::GetGroupName (uint32_t gid);

The user and group names are cached locally so that remote platforms can avoid
sending packets multiple times to resolve this information.

Added the parent process ID to the ProcessInfo class. 

Added a new ProcessInfoMatch class which helps us to match processes up
and changed the Host layer over to using this new class. The new class allows
us to search for processs:
1 - by name (equal to, starts with, ends with, contains, and regex)
2 - by pid
3 - And further check for parent pid == value, uid == value, gid == value, 
    euid == value, egid == value, arch == value, parent == value.
    
This is all hookup up to the "platform process list" command which required
adding dumping routines to dump process information. If the Host class 
implements the process lookup routines, you can now lists processes on 
your local machine:

machine1.foo.com % lldb
(lldb) platform process list 
PID    PARENT USER       GROUP      EFF USER   EFF GROUP  TRIPLE                   NAME
====== ====== ========== ========== ========== ========== ======================== ============================

This of course also works remotely with the lldb-platform:

The lldb-platform implements everything with the Host:: layer, so this should
"just work" for linux. I will probably be adding more stuff to the Host layer
for launching processes and attaching to processes so that this support should
eventually just work as well.

Modified the target to be able to be created with an architecture that differs
from the main executable. This is needed for iOS debugging since we can have
an "armv6" binary which can run on an "armv7" machine, so we want to be able
to do:

% lldb
(lldb) platform create remote-ios
(lldb) file --arch armv7 a.out

Where "a.out" is an armv6 executable. The platform then can correctly decide
to open all "armv7" images for all dependent shared libraries.

Modified the disassembly to show the current PC value. Example output:

(lldb) disassemble --frame
a.out`main:
   0x1eb7:  pushl  %ebp
   0x1eb8:  movl   %esp, %ebp
   0x1eba:  pushl  %ebx
   0x1ebb:  subl   $20, %esp
   0x1ebe:  calll  0x1ec3                   ; main + 12 at test.c:18
   0x1ec3:  popl   %ebx
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf
   0x1edb:  leal   213(%ebx), %eax
   0x1ee1:  movl   %eax, (%esp)
   0x1ee4:  calll  0x1f1e                   ; puts
   0x1ee9:  calll  0x1f0c                   ; getchar
   0x1eee:  movl   $20, (%esp)
   0x1ef5:  calll  0x1e6a                   ; sleep_loop at test.c:6
   0x1efa:  movl   $12, %eax
   0x1eff:  addl   $20, %esp
   0x1f02:  popl   %ebx
   0x1f03:  leave
   0x1f04:  ret
   
This can be handy when dealing with the new --line options that was recently
added:

(lldb) disassemble --line
a.out`main + 13 at test.c:19
   18  	{
-> 19  		printf("Process: %i\n\n", getpid());
   20  	    puts("Press any key to continue..."); getchar();
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf

Modified the ModuleList to have a lookup based solely on a UUID. Since the
UUID is typically the MD5 checksum of a binary image, there is no need
to give the path and architecture when searching for a pre-existing
image in an image list.

Now that we support remote debugging a bit better, our lldb_private::Module
needs to be able to track what the original path for file was as the platform
knows it, as well as where the file is locally. The module has the two 
following functions to retrieve both paths:

const FileSpec &Module::GetFileSpec () const;
const FileSpec &Module::GetPlatformFileSpec () const;

Greg Clayton e0d378b334 Fixed the LLDB build so that we can have private types, private enums and

abstract our API better.

Greg Clayton 1cb6496eb0 Did a lot more work on abtracting and organizing the platforms.
On Mac OS X we now have 3 platforms:
PlatformDarwin - must be subclassed to fill in the missing pure virtual funcs
                 but this implements all the common functionality between
                 remote-macosx and remote-ios. It also allows for another
                 platform to be used (remote-gdb-server for now) when doing
                 remote connections. Keeping this pluggable will allow for
                 flexibility.
PlatformMacOSX - Now implements both local and remote macosx desktop platforms.
PlatformRemoteiOS - Remote only iOS that knows how to locate SDK files in the
                    cached SDK locations on the host.

A new agnostic platform has been created:
PlatformRemoteGDBServer - this implements the platform using the GDB remote 
                          protocol and uses the built in lldb_private::Host
                          static functions to implement many queries.

2011-03-21 21:25:07 +00:00
Greg Clayton e996fd30be LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide
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.

Stephen Wilson bd58871d96 Host: linux: Use llvm::sys::getHostTriple for the default host ArchSpec.

on Linux where a valid OS component is needed.

Greg Clayton 64195a2c8b Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form
of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up
doing was:
- Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics
  the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple 
  to give us the machine type from llvm::Triple::ArchType.
- There is a new ArchSpec::Core definition which further qualifies the CPU
  core we are dealing with into a single enumeration. If you need support for
  a new Core and want to debug it in LLDB, it must be added to this list. In
  the future we can allow for dynamic core registration, but for now it is
  hard coded.
- The ArchSpec can now be initialized with a llvm::Triple or with a C string
  that represents the triple (it can just be an arch still like "i386").
- The ArchSpec can still initialize itself with a architecture type -- mach-o
  with cpu type and subtype, or ELF with e_machine + e_flags -- and this will
  then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core.
  The mach-o cpu type and subtype can be accessed using the getter functions:
  
  uint32_t
  ArchSpec::GetMachOCPUType () const;

  uint32_t
  ArchSpec::GetMachOCPUSubType () const;
  
  But these functions are just converting out internal llvm::Triple::ArchSpec 
  + ArchSpec::Core back into mach-o. Same goes for ELF.

All code has been updated to deal with the changes.

This should abstract us until later when the llvm::TargetSpec stuff gets
finalized and we can then adopt it.

Greg Clayton 93d3c8339c The DynamicLoader plug-in instance now lives up in lldb_private::Process where
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.

Greg Clayton 514487e806 Made lldb_private::ArchSpec contain much more than just an architecture. It
now, in addition to cpu type/subtype and architecture flavor, contains:
