Raphael Isemann 2d42579886 Fix some crashes and deadlocks in FormatAnsiTerminalCodes
Summary:
This patch fixes a few problems with the FormatAnsiTerminalCodes function:

* It does an infinite loop on an unknown color value.
* It crashes when the color value is at the end of the string.
* It deletes the first character behind the color token.

Also added a few tests that reproduce those problems (and test some other corner cases).

Pavel Labath 7cb4dfb083 Fix TestDataFormatterUnordered for older libc++ versions
clang recently started diagnosing "exception specification in
declaration does not match previous declaration" errors. Unfortunately
old libc++ versions had a bug, where they violated this rule, which
means that tests using this library version now fail due to build
errors.

Since it was easy to work around the bug by compiling this test with
-fno-exceptions, I do that here. If supporting old libc++ versions
becomes a burden, we'll have to revisit this.

The synthetic child providers for these classes had a type expression that matched

I fixed this by adding a way for the Synthetic Child FrontEnd provider to request dereference,
and then had these formatters use that mode.

Raphael Isemann a2e76c0bfc Replaced more boilerplate code with CompletionRequest (NFC)
Summary:
As suggested in D48796, this patch replaces even more internal calls that were using the old
completion API style with a single CompletionRequest. In some cases we also pass an option
vector/index, but as we don't always have this information, it currently is not part of the
CompletionRequest class.

The constructor of the CompletionRequest is now also more sensible. You only pass the
user input, cursor position and your list of matches to the request and the rest will be
inferred (using the same code we used before to calculate this). You also have to pass these
match window parameters to it, even though they are unused right now.

The patch shouldn't change any behavior.

Jonas Devlieghere 924d560867 Convert a location information from PDB to a DWARF expression
The current version of SymbolFilePDB::ParseVariableForPDBData function
always initializes variables with an empty location. This patch adds the
converter of a location information from PDB to a DWARF expression, so
it becomes possible to watch values of variables of primitive data
types. At the moment the converter supports only Static, TLS, RegRel,
Enregistered and Constant PDB location types, but it seems that it's
enough for most cases. There are still some problems with retrieving
values of variables (e.g. we can't watch variables of composite types),
but they look not relevant to the conversion to DWARF.

Raphael Isemann 4d51a90297 Get rid of the C-string parameter in DoExecute
Summary:
This patch gets rid of the C-string parameter in the RawCommandObject::DoExecute function,
making the code simpler and less memory unsafe.

There seems to be a assumption in some command objects that this parameter could be a nullptr,
but from what I can see the rest of the API doesn't actually allow this (and other command
objects and related code pieces dereference this parameter without any checks).

Especially CommandObjectRegexCommand has error handling code for a nullptr that is now gone.

Corrupted minidumps was leading to unpredictable behavior.

This change adds explicit consistency checks for the minidump early on. The
checks are not comprehensive but they should catch obvious structural violations:

streams with type == 0
duplicate streams (same type)
overlapping streams
truncated minidumps

Another early check is to make sure we actually support the minidump architecture
instead of crashing at a random place deep inside LLDB.

Lastly, ClearStackFrames is implemented in the base class, so individual thread implementations don't have to override it.

Davide Italiano 87951b6693 [testsuite] Implement a category to skip libstdcxx tests
On systems where it's not supported.
As far as I understand Linux is the only systems which now ships
with libstdcxx (maybe NetBSD?, but I'm not entirely sure of the
state of lldb on the platform).
We could make this more fine grained looking for the header as
we do for libcxx. This is a little tricky as there's no such
thing as /usr/include/c++/v1, but libstdcxx encodes the version
number in the path (i.e. /usr/include/c++/5.4). I guess we might
match a regex, but it seems fragile to me.

Raphael Isemann 3a0e12700b Refactor parsing of option lists with a raw string suffix.
Summary:
A subset of the LLDB commands follows this command line interface style:
   <command name> [arguments] -- <string suffix>
The parsing code for this interface has been so far been duplicated into the different
command objects which makes it hard to maintain and reuse elsewhere.

This patches improves the situation by adding a OptionsWithRaw class that centralizes
the parsing logic and allows easier testing. The different commands now just call this class to
extract the arguments and the raw suffix from the provided user input.

Stella Stamenova 67a19dfbcb Retrieve a function PDB symbol correctly from nested blocks
Summary:
This patch fixes a problem with retrieving a function symbol by an address in a nested block. In the current implementation of ResolveSymbolContext function it retrieves a symbol with PDB_SymType::None and then checks if found symbol's tag equals to PDB_SymType::Function. So, if nested block's symbol was found, ResolveSymbolContext does not resolve a function.

It is very simple to reproduce this. For example, in the next program

```
int main() {
  auto r = 0;
  for (auto i = 1; i <= 10; i++) {
    r += i & 1 + (i - 1) & 1 - 1;
  }

  return r;
}
```

if we will stop inside the cycle and will do a backtrace, the top element will be broken. But how we can test this? I thought to add an option to lldb-test to allow search a function by address, but the address may change when the compiler will be changed.

This test was trying to stop at a variety of std::vector calls.  It looks like the test
was failing because various inlined std functions left no line table entries for the line that
invoked the inlined function.  The author worked around that by undefining _LIBCPP_INLINE_VISIBILITY.

That's an internal libcxx macro, we really shouldn't be playing around with it.  Better to just force
ourselves to stop where we want using some other non-inlineable statement.  printf seems a good candidate...

It seems we both have the HAVE_LIBCOMPRESSION define in the config header

Config.h header emits the following warning when we compile the Host module:

```
In file included from <module-includes>:21:

        ^
<command line>:1:9: note: previous definition is here
        ^
```

It's not really clear why the define is in both places (the commit message
just says it fixes some unspecified bug), but we can easily work around this
by just guarding our define in Config.h.

Summary:
This change fixes one issue with `lldb.command`, and also reduces the implementation.

The fix: a command function's docstring was not shown when running `help <command_name>`. This is because the docstring attached the source function is not propagated to the decorated function (`f.__call__`). By returning the original function, the docstring will be properly displayed by `help`.

Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.

Additionally, the implementation was updated to:

* Remove inner class
* Remove use of `inspect` module
* Remove `*args` and `**kwargs`

Summary:

2) Update a couple of tests to reference pr37995 as their reason for failure since it is much more accurate. Support for floating point registers doesn't exist on Windows at all, rather than having issues.

Raphael Isemann 2443bbd4aa Refactoring for for the internal command line completion API (NFC)
Summary:
This patch refactors the internal completion API. It now takes (as far as possible) a single
CompletionRequest object instead o half a dozen in/out/in-out parameters. The CompletionRequest
contains a common superset of the different parameters as far as it makes sense. This includes
the raw command line string and raw cursor position, which should make the `expr` command
possible to implement (at least without hacks that reconstruct the command line from the args).

This patch is not intended to change the observable behavior of lldb in any way. It's also as
minimal as possible and doesn't attempt to fix all the problems the API has.

Some Q&A:

Q: Why is this not fixing all the problems in the completion API?
A: Because is a blocker for the expr command completion which I want to get in ASAP. This is the
smallest patch that unblocks the expr completion patch and which allows trivial refactoring in the future.
The patch also doesn't really change the internal information flow in the API, so that hopefully
saves us from ever having to revert and resubmit this humongous patch.

Q: Can we merge all the copy-pasted code in the completion methods
(like computing the current incomplete arg) into CompletionRequest class?
A: Yes, but it's out of scope for this patch.

Q: Why the `word_complete = request.GetWordComplete(); ... ` pattern?
A: I don't want to add a getter that returns a reference to the internal integer. So we have
to use a temporary variable and the Getter/Setter instead. We don't throw exceptions
from what I can tell, so the behavior doesn't change.

Q: Why are we not owning the list of matches?
A: Because that's how the previous API works. But that should be fixed too (in another patch).

Q: Can we make the constructor simpler and compute some of the values from the plain command?
A: I think this works, but I rather want to have this in a follow up commit. Especially when making nested
request it's a bit awkward that the parsed arguments behave as both input/output (as we should in theory
propagate the changes on the nested request back to the parent request if we don't want to change the
behavior too much).

Q: Can't we pass one const request object and then just return another result object instead of mixing
them together in one in/out parameter?
A: It's hard to get keep the same behavior with that pattern, but I think we can also get a nice API with just
a single request object. If we make all input parameters read-only, we have a clear separation between what
is actually an input and what an output parameter (and hopefully we get rid of the in-out parameters).

Q: Can we throw out the 'match' variables that are not implemented according to the comment?
A: We currently just forward them as in the old code to the different methods, even though I think
they are really not used. We can easily remove and readd them once every single completion method just
takes a CompletionRequest, but for now I prefer NFC behavior from the perspective of the API user.

This test makes sure we are able to read the shorter build-ids which are

To make this work, I've extended lldb-test to print the UUID of the

"module-sections" to "object-file" to reflect the fact it prints more
than just the sections.

I've also added the module Architecture to the output, so we could avoid
printing the entire symbol file information just to get the ArchSpec
details in the lc_version_min test (which was also the only test in it's

Pavel Labath 77c397f465 UUID: Add support for arbitrary-sized module IDs
Summary:
The data structure is optimized for the case where the UUID size is <=
20 bytes (standard length emitted by the GNU linkers), but larger sizes
are also possible.

I've modified the string conversion function to support the new sizes as
well. For standard UUIDs it maintains the traditional formatting
(4-2-2-2-6). If a UUID is shorter, we just cut this sequence short, and
for longer UUIDs it will just repeat the last 6-byte block as long as
necessary.

I've also modified ObjectFileELF to take advantage of the new UUIDs and
avoid manually padding the UUID to 16 bytes. While there, I also made
sure the computed UUID does not depend on host endianness.

Pavel Labath 2f93fd1f50 Represent invalid UUIDs as UUIDs with length zero
Summary:
During the previous attempt to generalize the UUID class, it was
suggested that we represent invalid UUIDs as length zero (previously, we
used an all-zero UUID for that). This meant that some valid build-ids
could not be represented (it's possible however unlikely that a checksum of
some file would be zero) and complicated adding support for variable
length build-ids (should a 16-byte empty UUID compare equal to a 20-byte
empty UUID?).

This patch resolves these issues by introducing a canonical
representation for an invalid UUID. The slight complication here is that
some clients (MachO) actually use the all-zero notation to mean "no UUID
has been set". To keep this use case working (while making it very
explicit about which construction semantices are wanted), replaced the
UUID constructors and the SetBytes functions with named factory methods.
- "fromData" creates a UUID from the given data, and it treats all bytes
  equally.
- "fromOptionalData" first checks the data contents - if all bytes are
  zero, it treats this as an invalid/empty UUID.

Jason Molenda 32a914256e A little cleanup in ObjectFileMachO::GetSDKVersion.
This method does one of two things:

1. finds a minimum os deployment version # in a Mach-O load
command and saves the three parts in the m_sdk_version, or

2. finds no valid min os version # load command, pushes a 
sentinel value on the m_sdk_version vector so we don't search
the same load commands multiple times.

There was a little bug when we found a load command with 
a version of 0.0.0 - the method would not add anything to
the m_sdk_version vector but would declare that a success.
It would not push the sentinel value to the vector.
There was code later in the method which assumed that
the vector always had a sentinel value, at least, and that
code could crash when this method was called back when
evaluating a Swift expression.  (these version #'s are 
fetched lazily so it wouldn't happen when the object file
was parsed, only when doing an expression that needed
the version #).

Pavel Labath f104d6b224 Fix TestThreadExit for gcc&libc++ combo
pseudo_barrier_wait() begins by decrementing an atomic variable. Since
these are always_inline in libc++, there is no line table anchor to
break on before we decrement it. This meant that on gcc we stopped after
the variable has been decremented, which meant that thread2 could have
exited, violating the test setup. On clang this wasn't a problem
because it generated some line table entries for the do{}while(0) loop
in the macro, so we still ended up stopping, before we touched the
variable.

I fix this by adding a dummy statement before the pseudo_barrier_wait()
command and setting the breakpoint there.
