Summary:
This enables us to avoid casts to "void *" in some cases and avoids a couple of "casts off const
qualifiers" warnings.

Originally, the source for the hidden lib_d and the regular lib_d were the same
file, so we always got the "correct" source for each. Splitting them up in
D11367 exposed a bug of showing the incorrect source file for the hidden lib_d.

Target and breakpoints options were added:
    breakpoint set --language lang --name func
    settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers).  If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

Summary:
The current Makefile scheme only allows one dylib to be specified in each make
invocation, so TestLoadUnload had a custom Makefile that's unrelated to the
base Makefile.rules. This change uses recursive make invocations to bypass the
single dylib restriction. See D11202 for more context.

Summary:
This commit integrates MainLoop into NativeProcessLinux. By registering a SIGCHLD handler with
the llgs main loop, we can get rid of the special monitor thread in NPL, which saves as a lot of
thread ping-pong when responding to client requests (e.g. qThreadInfo processing time has been
reduced by about 40%). It also makes the code simpler, IMHO.

This is a resubmission of r242305 after it was reverted due to bad interactions with the stdio
thread.

llvm-svn: 242783

Summary:
This commit removes the stdio forwarding thread in lldb-server in favor of a MainLoop callback.
As in some situations we need to forcibly flush the stream ( => Read() is called from multiple
places) and we still have multiple threads, I have had to additionally protect the communication
instance with a mutex.

Summary:
* Remove extraneous members that were just storing temporary
  values.
* ResultClass_e parameters don't need to be const as they are
  scalars.
* Switch from a map with CMIUtilString values to using a mapping
  function. This uses a switch statement which will generate
  a warning if a new result class is added.
* Make BuildRecordResult a static function rather than a private
  member function so that we can construct the result text
  correctly and avoid having extra stuff in the header.
* Don't need (void) parameter lists in C++.

I have observed an increased flakyness in the buildbots. I suspect something was relying on the
fact that Pipe::Write had an implicit timeout of 1s, which this commit has removed. Reverting
while I investigate.

Patch by Eugene Zelenko.

llvm-svn: 242765

Summary:
This commit adds a WriteWithTimeout method to time Pipe class, analogous to the existing
ReadWithTimeout(). It also changes the meaning of passing zero as a timeout value. Previously,
zero was used as an infinite timeout value. Now, the meaning of zero timeout to return the data
avaiable without sleeping (basically, a non-blocking operation). This makes the behaviour of Pipe
consistent with the Communication/Connection classes. For blocking operatios with infinite
timeout, I introduce a special constant for this purpose.

The session dictionary attached to a Python interpeter holds variables the user creates in the script interpreter
This can include objects that have complex state and need to be torn down intelligently (e.g. our SB* objects)

This will fail if the Python interpreter does not hold a valid thread state. So, acquire one, delete the session dictionary, and then let go of it on destruction

This fixes rdar://20960843

Correctly get the arguments and environment, even for processes that have a large amount or arguments and/or environment variables.

We previously passed in a 8192 byte buffer but this wasn't large enough. We now calculate the size we need and then add 128 to it and get the environment. If we pass exactly the number of bytes it says is needs, the sysctl() returns junk. Adding 1 seemed to do the trick, but to err on the side of caution, I added a few bytes more.

Changed the "jthreads" key/value in the stop reply packets to be "jstopinfo". This JSON only contains threads with valid stop reasons and allows us not to have to ask about other threads via qThreadStopInfo when we are stepping. The "jstopinfo" only gets sent if there are more than one thread since the stop reply packet contains all the info needed for a single thread.

Added a Process::WillPublicStop() in case process subclasses want to do any extra gathering for public stops. For ProcessGDBRemote, we end up sending a jThreadsInfo packet to gather all expedited registers, expedited memory and MacOSX queue information. We only do this for public stops to minimize the packets we send when we have multiple private stops. Multiple private stops happen when a source level single step, step into or step out run the process multiple times while implementing the stepping, and none of these private stops make it out to the UI via notifications because they are private stops.
