Greg Clayton 5b94e11873 When calling FileSpec::AppendPathComponent() we don't need to include "." in the path if m_filename is set to exactly '.'. Previously this would cause a FileSpec object that looked like:
m_directory = "/tmp"
m_filename = "."
                                         
To look like:

m_directory = "/tmp/."
m_filename = "foo.txt"

if "foo.txt" was appended to it. With this fix it will be:

m_directory = "/tmp"
m_filename = "foo.txt"

Sean Callanan 6681041d70 Added the concept of a Read-Eval-Print-Loop to LLDB.
A REPL takes over the command line and typically treats input as source code.
REPLs can also do code completion.  The REPL class allows its subclasses to
implement the language-specific functionality without having to know about the
IOHandler-specific internals.

Also added a PluginManager-based way of getting to a REPL given a language and
a target.

Also brought in some utility code and expression options that are useful for
REPLs, such as line offsets for expressions, ANSI terminal coloring of errors,
and a few IOHandler convenience functions.

Pavel Labath 3318314722 Fix temporary directory computation on linux (pr25147)
Summary:
On linux, the environment variables for temp directories that lldb checks for are generally not
defined, and the temp directory computation failed. This caused expression evaluation to fall
back to creating "/tmp/lldb-*.expr" debugging files instead of the usual
"$TMP/lldb/pid/lldb-*.expr". Crucially, these files were not cleaned up on lldb exit, which
caused clutter in the /tmp folder, especially on long-running machines (e.g. builtbots). This
commit fixes lldb to use llvm::sys::path::system_temp_directory, which does the same environment
variable dance, but (!) also falls back to the P_tmpdir macro, which is how the temp directory is
defined on linux.

Since the linux temp path computation now succeeds, I needed to also modify Android path
computation to check for actual directory existence, rather then checking whether the operation
failed.

Zachary Turner 9c40264fda Introduce a `PythonFile` object, and use it everywhere.
Python file handling got an overhaul in Python 3, and it affects
the way we have to interact with files.  Notably:

1) `PyFile_FromFile` no longer exists, and instead we have to use
   `PyFile_FromFd`.  This means having a way to get an fd from
   a FILE*.  For this we reuse the lldb_private::File class to
   convert between FILE*s and fds, since there are some subtleties
   regarding ownership rules when FILE*s and fds refer to the same
   file.
2) PyFile is no longer a builtin type, so there is no such thing as
   `PyFile_Check`.  Instead, files in Python 3 are just instances
   of `io.IOBase`.  So the logic for checking if something is a file
   in Python 3 is to check if it is a subclass of that module.

Additionally, some unit tests are added to verify that `PythonFile`
works as expected on Python 2 and Python 3, and
`ScriptInterpreterPython` is updated to use `PythonFile` instead of
manual calls to the various `PyFile_XXX` methods.

Todd Fiala 7df337f85c ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
  unknown to a specified unknown when both the ArchSpec and the merged
  in ArchSpec were both unspecified unknowns. This no longer happens,
  which fixes issues with global module cache lookup in some
  situations.

* Added ArchSpec::DumpTriple(Stream&) that now properly prints
  unspecified unknowns as '*' and specified unknows as 'unknown'.
  This makes it trivial to tell the difference between the two.
  Converted printing code over ot using DumpTriple() rather than
  building from scratch.

* Fixed up a couple places that were not guaranteeing that an
  unspecified unknown was recorded as such.

Jason Molenda 8825c5c9b4 Re-commit the (fixed) changes from r248985 which were reverted by Pavel
when they introduced android testsuite regressions.  Pavel has run the
testsuite against the updated patch and it completes cleanly now.

The original commit message:


Fixing a subtle issue on Mac OS X systems with dSYMs (possibly
introduced by r235737 but I didn't look into it too closely).

A dSYM can have a per-UUID plist in it which tells lldb where
to find an executable binary for the dSYM (DBGSymbolRichExecutable)
- other information can be included in this plist, like how to
remap the source file paths from their build pathnames to their
long-term storage pathnames.

This per-UUID plist is a unusual; it is used probably exclusively
inside apple with our build system.  It is not created by default
in normal dSYMs.

The problem was like this:

  1. lldb wants to find an executable, given only a UUID
     (this happens when lldb is doing cross-host debugging
      and doesn't have a copy of the target system's binaries)

  2. It eventually calls LocateMacOSXFilesUsingDebugSymbols
     which does a spotlight search for the dSYM on the local
     system, and failing that, tries the DBGShellCommands
     command to find the dSYM.

  3. It gets a dSYM.  It reads the per-UUID plist in the dSYM.
     The dSYM has a DBGSymbolRichExecutable kv pair pointing to
     the binary on a network filesystem.

  4. Using the binary on the network filesystem, lldb now goes
     to find the dSYM.

  5. It starts by looking for a dSYM next to the binary it found.

  6. lldb is now reading the dSYM over a network filesystem,
     ignoring the one it found on its local filesystem earlier.

Everything still *works* but it's much slower.

This would be a tricky one to write up in a testsuite case;
you really need the binary to not exist on the local system.
And LocateMacOSXFilesUsingDebugSymbols will only compile on
Mac OS X - even if I found a way to write up a test case, it
would not run anywhere but on a mac.

One change Greg wanted while I was touching this code was to
have LocateMacOSXFilesUsingDebugSymbols (which could be asked
to find a binary OR find a dSYM) to instead return a ModuleSpec
with the sum total of everything it could find.  This
change of passing around a ModuleSpec instead of a FileSpec
was percolated up into ModuleList::GetSharedModule.

The changes to LocateMacOSXFilesUsingDebugSymbols look larger
than they really are - there's a lot of simple whitespace changes
in there.

I ran the testsuites on mac, no new regressions introduced

Bruce Mitchener eb284e4667 Fix segmentation fault in lldb_private::Symbols::LocateExecutableSymbolFile()
Summary:
When `module_spec.GetFileSpec().GetDirectory().AsCString()` returned a `nullptr` this line caused a segmentation fault:

`std::string module_directory = module_spec.GetFileSpec().GetDirectory().AsCString()`

Some context:
I was remote debugging an executable built with Clang in an Ubuntu VM on my Windows machine using lldb-mi. I copied the executable and nothing else from the Ubuntu VM to the Windows machine.

Then started lldb-server in the Ubuntu VM:

```
./bin/lldb-server gdbserver *:8888 -- /home/enlight/Projects/dbgmits/build/Debug/data_tests_target
```

And ran `lldb-mi --interpreter` on Windows with the following commands:

```
-file-exec-and-symbols C:\Projects\data_tests_target
-target-select remote 192.168.56.101:8888
-exec-continue

```

After which the segmentation fault occurred at the aforementioned line. Inside this method `module_spec.GetFileSpec()` returns an empty `FileSpec` (no dir, no filename), while `module_spec.GetSymbolFileSpec().GetFilename()` returns `"libc-2.19.so"`.

Patch thanks to Vadim Macagon.

See:

not part of the lldb.dylib path, the supporting
executable path is resolved to be the bin directory
sitting next to the lib directory with the dylib

base it on the executable path since both Python

Sean Callanan db7d8083cd Added support for resolving symbolic links to FileSpec.
We use the symbolic link to resolver to find the target of the LLDB shlib
symlink if there is a symlink.  This allows us to find shlib-relative  resources
even when running under the testsuite, where _lldb.so is a symlink in the Python
resource directory.

Also changed a comment to be slightly more clear about what resolve_path in the
constructor for FileSpec means, since if we were actually using realpath() this
code wouldn't have been necessary.

Zachary Turner 022c3c85df When redirecting stdio, use FILE_SHARE_DELETE.
Some tests were failing because the test would try to delete the
file before inferior had exited, but on Windows this will fail by
default unless you specify FILE_SHARE_DELETE when opening the file.

Can't think of a good reason not to do this, so here it is.
