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.

This patch removes the comments grouping header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

- Add latency timings to GDB packet log summary if timestamps are on log
- Add the ability to plot the latencies for each packet type with --plot
- Don't crash the script when target xml register info is in wierd format
|
|
|
|
Fixes include:
- fix all lint errors
- add code that will automatically register and LLDB command classes by detecting the classes and any classes that have a "register_lldb_command" function
- automatically fill in the correct module name when registering commands
- automatically fill in the class name when registering command

This is a combination stand alone BSD archive tool that can dump BSD archives:
% bsd.py /path/to/foo.a
Search archives for an object file:
% bsd.py --object foo.o bar.a
Dump the symbol definitions found in the __.SYMDEF objects:
% bsd.py --symdef bar.a
Find symbols by name that are listed in the __.SYMDEF objects:
% bsd.py --symbol _Z123 bar.a
Extract objects from BSD archives:
% bsd.py --object foo.o bar.a --extract
% bsd.py --object foo.o bar.a --extract --outfile /tmp/foo.o
% bsd.py --object foo.o bar.a --extract --mtime 0x1234556
It also has installs a new LLDB command line command when imported into LLDB:
(lldb) command script import ~/Dropbox/bin/bsd.py
The "verify-debug-map-objects" command has been installed, type "help verify-debug-map-objects" for detailed help.
(lldb) verify-debug-map-objects a.out
This will iterate through all object files and verify the modification times match for any .o files, it will verify any .o files from BSD archives are found and have matching modification times and print out errors if any are found.

Summary:
A couple of members of these data structures have been renamed in recent
months. This makes sure they still work with the latest libc++ version.

This version relies on a newer and more convenient way
to use a class to implement a command. It has been in place
since early 2015, so it should be pretty safe to use.

lldb.process. That hasn't worked for a long time. Convert it
to the form that takes an SBExecutionContext and use that instead.
|
|
When the expression parser does name resolution for local
variables in C++ closures it doesn't give the local name
priority over other global symbols of the same name. heap.py
uses "info" which is a fairly common name, and so the commands
in it fail. This is a workaround, just use lldb_info not info.

Sometimes you want to step along and print a local each time as you go.
You can do that with stop hooks, but that's a little heavy-weight. This
is a sketch of a command that steps and then does "frame variable" on all
its arguments.
|
|
Sometimes you are debugging in source, but you really only want to see
the disassembly. That's easy to do but you have to set a few variables.
This command toggles between your old values, and a disassembly only mode.

Not much we can do about it but at least we can print the bad
plist and the error.

*** 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.

This class enables one to easily write a synthetic child provider by writing a class that returns pairs of names and primitive Python values - the base class then converts those into LLDB SBValues

execution context now that the @lldb.command decorator does the right thing for the command function that takes 5 arguments.
A few fixes:
- Check the process state to make sure it is stopped
- Grab the frame from the "exe_ctx" so this will work during breakpoint callbacks
- Print out the SBDeclaration objects of the variables that shadow each other so we can see the source locations of which variable declarations are shodowing each other.

This shows how to grab individual blocks from stack frames and get only the variables from those blocks. It then will iterate over all of the parent blocks and look for shadowed variables.

CreateChildAtOffset needs a byte offset, not an element number.

This patch fixes a bunch of issues that show up on big-endian systems:
- The gnu_libstdcpp.py script doesn't follow the way libstdc++ encodes
bit vectors: it should identify the enclosing *word* and then access
the appropriate bit within that word. Instead, the script simply
operates on bytes. This gives the same result on little-endian
systems, but not on big-endian.
- lldb_private::formatters::WCharSummaryProvider always assumes wchar_t
is UTF16, even though it could also be UTF8 or UTF32. This is mostly
not an issue on little-endian systems, but immediately fails on BE.
Fixed by checking the size of wchar_t like WCharStringSummaryProvider
already does.
- ClangASTContext::GetChildCompilerTypeAtIndex uses uint32_t to access
the virtual base offset stored in the vtable, even though the size
of this field matches the target pointer size according to the C++
ABI. Again, this is mostly not visible on LE, but fails on BE.
- Process::ReadStringFromMemory uses strncmp to search for a terminator
consisting of multiple zero bytes. This doesn't work since strncmp
will stop already at the first zero byte. Use memcmp instead.

Old-style syntax: `except Exception, e:`
New-style syntax: `except Exception as e:`
These two statements are identical, except that the former has
been deprecated for may versions, and was removed in Python 3.
This converts everything to use the new syntax (which also works
in Python 2). I had to convert unittest2 as well. What we really
need to do is just delete unittest2, and use unittest instead since
it is a standard module that ships with every Python distribution.
But this is the path of least resistance for now, although at
some point we will really need to do it.

Even though these are under examples/, they actually get loaded
when LLDB starts up during initialization of ScriptInterpreterPython.
There's obviously some kind of layering issue here (and comments
in the code even point to that as well), but for now just make them
py3 compatible.
