Ed Maste 02983be252 Set thread names on FreeBSD
Also move the logic to shorten thread names from linux/Host.cpp to a new
SetShortThreadName as both FreeBSD and Linux need the functionality.

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.

Greg Clayton 7b0992d9cd After discussing with Chris Lattner, we require C++11, so lets get rid of the macros and just use C++11.
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.

Greg Clayton 8571963a7c Fixed a case where the result of std::string's c_str() method was being called on a local variable and returned as a const char * incorrectly. We used to cache the thread names for threads in the current host process, but we shoudn't be caching that as the names can change over time, so now a std::string is returned from Host::GetThreadName().

Greg Clayton a0ca6601bc <rdar://problem/12462048>
<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.

Filipe Cabecinhas b018345ddc We shouldn't save g_dummy_target_sp. Other code will simply call Destroy() on it.
TestBackticksWithoutATarget.BackticksWithNoTargetTestCase was calling
GetDummyTarget() when executing for x86_64. When performing session
tearDown, it would get destroyed (and everything would be invalid (arch,
etc).

Then the test would run for i386. The dummy target wasn't being
reinitialized and was invalid. lldb complained that 'current process state
is unsuitable for expression parsing'.

2012-05-15 02:44:13 +00:00
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.

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.

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.

llvm-svn: 144918
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.
