Zachary Turner 97a14e60b2 Move some Host logic into HostInfo class.
This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform.  As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.

This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.

Zachary Turner c00cf4a068 Move FileSystem functions out of Host and into their own classes.
More specifically, this change can be summarized as follows:
1) Makes an lldbHostPosix library which contains code common to
   all posix platforms.
2) Creates Host/FileSystem.h which defines a common FileSystem
   interface.
3) Implements FileSystem.h in Host/windows and Host/posix.
4) Creates Host/FileCache.h, implemented in Host/common, which
   defines a class useful for storing handles to open files needed
   by the debugger.

Zachary Turner 696b52878f Refactor FileAction out of ProcessLaunchInfo.
FileAction was previously a nested class in ProcessLaunchInfo.
This led to some unfortunate style consequences, such as requiring
the AddPosixSpawnFileAction() funciton to be defined in the Target
layer, instead of the more appropriate Host layer.  This patch
makes FileAction its own independent class in the Target layer,
and then moves AddPosixSpawnFileAction() into Host as a result.

Zachary Turner df62f20c75 Fix FileSpec to be able to understand Windows paths.
This patch adds the notion of a "path syntax" to FileSpec.  There
are two syntaxes (Posix and Windows) and one "meta syntax",
Host Native, which uses the current platform to figure out the
appropriate syntax for host paths.

This allows paths from one platform to be represented and
manipulated on another platform even if they have different path
syntaxes.

Todd Fiala 015d818b59 Enable lldb-platform exe support for Linux.
This change enables lldb-platform for Linux.  In addition, it does the following:

* fixes Host::GetLLDBPath() to work on Linux/*BSD for ePathTypeSupportExecutableDir-relative paths.

* adds more logging and comments around lldb-platform startup and remote lldb-platform usage.

* refactors lldb-platform remote-* support for Darwin and Linux into PlatformPOSIX.  This, in theory, is the bulk of what is needed for *BSD to make remote connections to lldb-platform as well (although I haven't tested that yet).  FreeBSD can make similar changes to their Platform* as was made here for PlatformLinux to pick up the rest of the bits.

* teaches GDBRemoteCommunication to use lldb-gdbserver for non-Apple hosts.

Zachary Turner c9bf0c70b5 Make lldb -P work on Windows.
lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module.  This
Host functionality was unimplemented on Windows, so this patch
implements it.  Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

Todd Fiala 17096d7669 Add Host::MAX_THREAD_NAME_LENGTH constant.
This value gets set to a max uint32_t value when there is no known limit; otherwise,
it is set to a value appropriate for the platform.  For the moment, only
Linux, FreeBSD and NetBSD set it to 16.  All other platforms set it to
the max uint32_t value.

Modifies the Process private state thread names to fit within a 16-character limit
when the max thread name length is <= 16.  These guarantee that the thread names
can be distinguished within the first 16 characters.  Prior to this change, those
threads had names in the final dotted name segment that were not distinguishable
within the first 16 characters.

This patch implements basic functionality of the "platform process

* Certain types of filtering are not enabled (e.g. filtering by

* The username of the process is not yet obtained.
* Using -v to list verbose information generates an error.
* The architecture column displays the entire triple, leading to
  misaligned formatting of the printed table.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")

First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.

Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

default signal handlers on the spawned process after this change.

Todd Fiala 76747120ca Unify OS X/POSIX/Linux Host spawn support.
This fixes a bug under Linux where spawning a process via
Host::LaunchProcess was disabling all blockable signals on the
launched process.  This caused strange behavior when attempting
to kill the lldb-gdbserver process, as the child generally would
not die unless killed with a non-blockable signal (e.g. 'kill -9').

This change moves several functions out of macosx/Host.mm into
common/Host.cpp.  In addition, two functions that needed to work
across common/Host.cpp and macosx/Host.mm were moved into the Host.h
header file.

Todd Fiala a9ddb0e14f Added distribution info to ArchSpec and qHostInfo message.
ArchSpec now contains an optional distribution_id, with getters and
setters. Host::GetArchitecture () sets it on non-Apple platforms using
Host::GetDistributionId (). The distribution_id is ignored during
ArchSpec comparisons.

The gdb remote qHostInfo message transmits it, if set, via the
distribution_id={id-value} key/value pair. Updated gdb remote docs to
reflect this change.

As before, GetDistributionId () returns nothing on non-Linux platforms
at this time. On Linux, it is returned only if the lsb_platform
command is installed (in /bin or /usr/bin), and only if the
distributor id key is returned by 'lsb_platform -i'. This id is
lowercased, and whitespace is replaced with underscores.

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.
