Leonard Mosescu 3da16f8393 Fix a bug in VMRange
I noticed a suspicious failure:

[ RUN ] VMRange.CollectionContains
llvm/src/tools/lldb/unittests/Utility/VMRangeTest.cpp:146: Failure
Value of: VMRange::ContainsRange(collection, VMRange(0x100, 0x104))

Actual: false
Expected: true

Looking at the code, it is a very real bug:

class RangeInRangeUnaryPredicate {
public:
  RangeInRangeUnaryPredicate(VMRange range) : _range(range) {} // note that _range binds to a temporary!
  bool operator()(const VMRange &range) const {
    return range.Contains(_range);
  }
  const VMRange &_range;
};

This change fixes the bug.

Summary:
pudb and pdb interfere with the behavior of the inspect module. calling
`inspect.getfile(inspect.currentframe())` returns a different result
depending on whether or not you're in a debugger. Calling
`os.path.abspath` on the result of `inspect.getfile(...)` normalizes the
result between the two environments.

Raphael Isemann 286ac07199 Add raw_ostream wrapper to the Stream class
Summary:
This wrapper will allow us in the future to reuse LLVM methods from within the
Stream class.

Currently no test as this is intended to be an internal class that shouldn't have any
NFC. The test for this change will be the follow up patch that migrates LLDB's
LEB128 implementation to the one from LLVM.

This change also adds custom move/assignment methods to Stream, as LLVM
raw_ostream doesn't support these. As our internal stream has anyway no state,
we can just keep the same stream object around.

Raphael Isemann 92b16738a1 Add byte counting mechanism to LLDB's Stream class.
Summary:
This patch allows LLDB's Stream class to count the bytes it has written to so far.

There are two major motivations for this patch:

The first one is that this will allow us to get rid of all the handwritten byte counting code
we have in LLDB so far. Examples for this are pretty much all functions in LLDB that
take a Stream to write to and return a size_t, which usually represents the bytes written.

By moving to this centralized byte counting mechanism, we hopefully can avoid some
tricky errors that happen when some code forgets to count the written bytes while
writing something to a stream.

The second motivation is that this is needed for the migration away from LLDB's `Stream`
and towards LLVM's `raw_ostream`. My current plan is to start offering a fake raw_ostream
class that just forwards to a LLDB Stream.

However, for this raw_ostream wrapper we need to fulfill the raw_ostream interface with
LLDB's Stream, which currently lacks the ability to count the bytes written so far (which
raw_ostream exposes by it's `tell()` method). By adding this functionality it is trivial to start
rolling out our raw_ostream wrapper (and then eventually completely move to raw_ostream).

Also, once this fake raw_ostream is available, we can start replacing our own code writing
to LLDB's Stream by LLVM code writing to raw_ostream. The best example for this is the
LEB128 encoding we currently ship, which can be replaced with by LLVM's version which
accepts an raw_ostream.

From the point of view of the pure source changes this test does, we essentially just renamed
the Write implementation in Stream to `WriteImpl` while the `Write` method everyone is using
to write its raw bytes is now just forwarding and counting the written bytes.

Summary:
This patch adds syntax highlighting support to LLDB. When enabled (and lldb is allowed
to use colors), printed source code is annotated with the ANSI color escape sequences.

So far we have only one highlighter which is based on Clang and is responsible for all
languages that are supported by Clang. It essentially just runs the raw lexer over the input
and then surrounds the specific tokens with the configured escape sequences.

Alex Langford 36706fd977 Introduce install-lldb-framework target
Summary:
Previously, I thought that install-liblldb would fail because CMake had
a bug related to installing frameworks. In actuality, I misunderstood the
semantics of `add_custom_target`: the DEPENDS option refers to specific files,
not targets. Therefore `install-liblldb` should rely on the actual liblldb
getting generated rather than the target.

This means that the previous patch I committed (to stop relying on CMake's
framework support) is no longer needed and has been reverted. Using CMake's
framework support greatly simplifies the implementation.

`install-lldb-framework` (and the stripped variant) is as simple as
depending on `install-liblldb` because CMake knows that liblldb was built as a
framework and will install the whole framework for you. The stripped variant
will depend on the stripped variants of individual tools only to ensure they
actually are stripped as well.

Raphael Isemann 1a6d7ab55d Narrow the CompletionRequest API to being append-only.
Summary:
We currently allow any completion handler to read and manipulate the list of matches we
calculated so far. This leads to a few problems:

Firstly, a completion handler's logic can now depend on previously calculated results
by another handlers. No completion handler should have such an implicit dependency,
but the current API makes it likely that this could happen (or already happens). Especially
the fact that some completion handler deleted all previously calculated results can mess
things up right now.

Secondly, all completion handlers have knowledge about our internal data structures with
this API. This makes refactoring this internal data structure much harder than it should be.
Especially planned changes like the support of descriptions for completions are currently
giant patches because we have to refactor every single completion handler.

This patch narrows the contract the CompletionRequest has with the different handlers to:

1. A handler can suggest a completion.
2. A handler can ask how many suggestions we already have.

Point 2 obviously means we still have a  dependency left between the different handlers, but
getting rid of this is too large to just append it to this patch.

Otherwise this patch just completely hides the internal StringList to the different handlers.

The CompletionRequest API now also ensures that the list of completions is unique and we
don't suggest the same value multiple times to the user. This property has been so far only
been ensured by the `Option` handler, but is now applied globally. This is part of this patch
as the OptionHandler is no longer able to implement this functionality itself.

So far lldb is printing this when it finds an ambiguous command:

Ambiguous command 'g'. Possible matches:
        gdb-remote

        gdb-remote
        gui
```
The duplicates come from the fact that we call the same query twice with the same parameters
and add it to the same list. This patch just removes the second query call to `GetCommandObject`.

As `GetCommandObject` is const and the name parameter is also not modified, this shouldn't break
anything else. I didn't merge the remaining if statement into the else as I think otherwise the
`if obj==nullptr do X else Y` pattern in there becomes hard to recognize.
