Rosetta crashlogs can have their own thread register state. Unlike the
other registers which ware directly listed under "threadState", the
Rosetta registers are nested under their own key in the JSON, as
illustrated below:
{
"threadState":
{
"rosetta":
{
"tmp2":
{
"value": 4935057216
},
"tmp1":
{
"value": 4365863188
},
"tmp0":
{
"value": 18446744073709551615
}
}
}
}
Convert the `crashlog` command to be implemented as a class. The `Symbolicate`
function is switched to a class, to implement `get_long_help`. The text for the
long help comes from the help output generated by `OptionParser`. That is, the
output of `help crashlog` is the same as `crashlog --help`.

JSON crashlogs have an optional field named reportNotes that contains
any potential errors encountered by the crash reporter when generating
the crashlog. Parse and display them in LLDB.

Gracefully deal with JSON crashlogs that don't have thread state
available and print an error saying as much: "No thread state (register
information) available".

JSON crashlogs normally start with a single line of meta data that we
strip unconditionally. Some producers started omitting the meta data
which tripped up crashlog. Be more resilient by only removing the first
line when we know it really is meta data.

mdfind can return multiple results, some of which are not even dSYM
bundles, but Xcode archives (.xcrachive).
Currently, we end up concatenating the paths, which is obviously bogus.
This patch not only fixes that, but now also skips paths that don't have
a Contents/Resources/DWARF subdirectory.

- The register encoding state in the JSON crashlog format changes.
Update the parser accordingly.
- Print the register state when printing the symbolicated thread.
The binary image list contains the following entry when a frame is not
found in any know binary image:
{
"size" : 0,
"source" : "A",
"base" : 0,
"uuid" : "00000000-0000-0000-0000-000000000000"
}
Note that this object is missing the name and path keys. This patch
makes the JSON parser resilient against their absence.
Add a parser for JSON crashlogs. The CrashLogParser now defers to either
the JSONCrashLogParser or the TextCrashLogParser. It first tries to
interpret the input as JSON, and if that fails falling back to the
textual parser.

The lldb.debugger et al convenience variables are only available from
the interactive script interpreter. In all other scenarios, they are
None (since fc1fd6bf9f) before that they
were default initialized.
The crashlog script was hacking around that by setting the lldb.debugger
to a newly created debugger instance when running outside of the script
interpreter, which works fine until lldb creates a script interpreter
instance under the hood and clears the variables. This was resulting in
an AttributeError when invoking the script directly (from outside of
lldb):
AttributeError: 'NoneType' object has no attribute 'GetSourceManager'
This patch fixes that by passing around the debugger instance.

Instead of parsing the crashlog in one big loop, use methods that
correspond to the different parsing modes.

Python doesn't support enums before PEP 435, but using a class with
constants is how it's commonly emulated. It can be converted into a real
Enum (in Python 3.4 and later) by extending the Enum class:
class CrashLogParseMode(Enum):
NORMAL = 0
THREAD = 1
IMAGES = 2
THREGS = 3
SYSTEM = 4
INSTRS = 5
This property is explicitly for use only in the interactive editor,
and NOT in commands. It's use worked until we got more careful about
not leaving lldb.target lying around in the script interpreter.
I also added a quick sniff test for the save_crashlog command.

This is yet another change to the regular expressions in crashlog.py
that fix a few edge cases, and attempt to improve the readability
quite a bit in the process. My last change to support spaces in
filenames introduced a bug that caused the version/archspec field to
be parsed as part of the image name.
For example, in "0x1111111 - 0x22222 +MyApp Pro arm64 <01234>", the
name of the image was recognized as "MyApp Pro arm64" instead of
"MyApp Pro" with a "version" of arm64.
The bugfix makes the space following an optional field mandatory
*inside* the optional group.

For end-users there is no point in printing dSYM load errors for
system frameworks, since they will all fail and there's nothing they
can do about it. This patch hides them by default and shows them when
--verbose is present.

Generally having spurious `\n` doesn't matter, but here the
returning string is a command which is executed, so we want
to strip it. Pointed out by Jason.

Summary:
The method find_matching_slice(self) uses uuid_str on one of the paths but the variable does not exist and so this results in a NameError exception if we take that path.

This is a little dangerous since the crashlog files aren't 100%
unambiguous, but the risk is mitigated by using a non-greedy +?
pattern.

Often users have a crash log an d a .dSYM bundle, but not the original
application binary. It turns out that for crash symbolication, we can
safely fall back to using the binary inside the .dSYM bundle.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

version of this script. We picked up a bug at some point in March
where scripts that fail to call SBDebugger::Destroy() will crash
in the Debugger C++ dtor. I want to track the change down which
introduced the change - but this script should be calling
SBDebugger::Destroy() in the first place, so do that.
