Raphael Isemann d752b75d7f [lldb][NFC] Simplify regex_chars in CommandCompletions 2019-11-29 12:34:23 +01:00
Pavel Labath 38870af859 [lldb] Remove FileSpec->CompileUnit inheritance
Summary:
CompileUnit is a complicated class. Having it be implicitly convertible
to a FileSpec makes reasoning about it even harder.

This patch replaces the inheritance by a simple member and an accessor
function. This avoid the need for casting in places where one needed to
force a CompileUnit to be treated as a FileSpec, and does not add much
verbosity elsewhere.

It also fixes a bug where we were wrongly comparing CompileUnit& and a
CompileUnit*, which compiled due to a combination of this inheritance
and the FileSpec*->FileSpec implicit constructor.

Jonas Devlieghere bb090bb1ca [Reproducer] Make 'reproducer xcrash' behave the same during capture & replay
There's no point in preventing this command from running during replay.
We should simulate the same crash as during capture.

Adrian McCarthy 3b69f0c555 [NFC] Refactor and improve comments in CommandObjectTarget
Made small improvements while debugging through
CommandObjectTarget::AddModuleSymbols.

1.  Refactored error case for an early out, reducing the indentation of
the rest of this long function.
2.  Clarified some comments by correcting spelling and punctuation.
3.  Reduced duplicate code at the end of the function.

Tested with `ninja check-lldb`

Jonas Devlieghere c8dfe90729 [Reproducer] Generate LLDB reproducer on crash
This patch hooks the reproducer infrastructure with the signal handlers.
When lldb crashes with reproducers capture enabled, it will now generate
the reproducer and print a short message the standard out. This doesn't
affect the pretty stack traces, which are still printed before.

This patch also introduces a new reproducer sub-command that
intentionally raises a given signal to test the reproducer signal
handling.

Currently the signal handler is doing too much work. Instead of copying
over files into the reproducers in the signal handler, we should
re-invoke ourselves with a special command line flag that looks at the
VFS mapping and performs the copy.

This is a NO-OP when reproducers are disabled.

Jonas Devlieghere 0cf86da174 [Reproducer] Quit the debugger after generating a reproducer
Currently nothing prevents you from continuing your debug session after

prevent this from causing bugs in the future.

Pavel Labath 28cf9698ab MemoryRegion: Print "don't know" permission values as such
Summary:
The permissions in a memory region have ternary states (yes, no, don't
know), but the memory region command only prints in binary, treating
"don't know" as "yes", which is particularly confusing as for instance
the unwinder will treat an unknown value as "no".

This patch makes is so that we distinguish all three states when
printing the values, using "?" to indicate the lack of information. It
is implemented via a special argument to the format provider for the
OptionalBool enumeration.

Jim Ingham 738af7a624 Add the ability to pass extra args to a Python breakpoint callback.
For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
    it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
    way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
    command to a breakpoint.

    With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
    the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
    signature) when the breakpoint is hit. Then in lldb, you can say:

    (lldb) break com add -F caller_is -k caller_name -v Foo

    More generally this will allow us to write reusable Python breakpoint commands.

We need a way to show all the processes on android regardless of the user id.

Aleksandr Urakov 30c2441a32 [Windows] Use information from the PE32 exceptions directory to construct unwind plans
This patch adds an implementation of unwinding using PE EH info. It allows to
get almost ideal call stacks on 64-bit Windows systems (except some epilogue
cases, but I believe that they can be fixed with unwind plan disassembly
augmentation in the future).

To achieve the goal the CallFrameInfo abstraction was made. It is based on the
DWARFCallFrameInfo class interface with a few changes to make it less
DWARF-specific.

To implement the new interface for PECOFF object files the class PECallFrameInfo
was written. It uses the next helper classes:

- UnwindCodesIterator helps to iterate through UnwindCode structures (and
  processes chained infos transparently);
- EHProgramBuilder with the use of UnwindCodesIterator constructs EHProgram;
- EHProgram is, by fact, a vector of EHInstructions. It creates an abstraction
  over the low-level unwind codes and simplifies work with them. It contains
  only the information that is relevant to unwinding in the unified form. Also
  the required unwind codes are read from the object file only once with it;
- EHProgramRange allows to take a range of EHProgram and to build an unwind row
  for it.

So, PECallFrameInfo builds the EHProgram with EHProgramBuilder, takes the ranges
corresponding to every offset in prologue and builds the rows of the resulted
unwind plan. The resulted plan covers the whole range of the function except the
epilogue.

Raphael Isemann 95e264fc8a [lldb][NFC] Remove strange bool parameter from Searcher::SearchCallback
Summary:
The SearchCallback has a bool parameter that we always set to false, we never use in any callback implementation and that also changes its name
from one file to the other (either `containing` and `complete`). It was added in the original LLDB check in, so there isn't any history what
this was supposed to be, so let's just remove it.

Lawrence D'Anna 609010d063 protect libedit and LLDB gui from receiving null FILE* streams
Summary:
We now have valid files that will return NULL from GetStream().
libedit and the LLDB gui are the only places left that need FILE*
streams.  Both are doing curses-like user interaction that only
make sense with a real terminal anyway, so there is no need to convert
them off of their use of FILE*.   But we should check for null streams
before enabling these features.

Raphael Isemann dab6f0746d [lldb] Reland 370734: Test 'frame select -r' and fix that INT32_MIN breaks the option parser
The problem with r370734 was that it removed the code for resetting the options in
OptionParsingStarting. This caused that once a 'frame select -r ...' command was executed,
we kept the relative index argument for all following 'frame select ...' invocations (even
the ones with an absolute index as they are the same command object). See rdar://55791276.

This relands the patch but keeps the code that resets the command options before execution.

Raphael Isemann 5a039d5571 [lldb] Partly revert 370734: Test 'frame select -r' and fix that INT32_MIN breaks the option parser
This somehow caused that 'frame select X' ends up being interpreted as 'frame select -r 1' when 'up' or 'down'
were run before 'frame select X'. See rdar://55791276.
Partly reverting to unbreak master. The changes that aren't reverted are the generic 'frame select -r' tests
that are obviously NFC and test existing behavior.

Lawrence D'Anna 7ca15ba73f remove File::SetStream(), make new files instead.
Summary:
This patch removes File::SetStream() and File::SetDescriptor(),
and replaces most direct uses of File with pointers to File.
Instead of calling SetStream() on a file, we make a new file and
replace it.

My ultimate goal here is to introduce a new API class SBFile, which
has full support for python io.IOStream file objects.   These can
redirect read() and write() to python code, so lldb::Files will
need a way to dispatch those methods.   Additionally it will need some
form of sharing and assigning files, as a SBFile will be passed in and
assigned to the main IO streams of the debugger.

In my prototype patch queue, I make File itself copyable and add a
secondary class FileOps to manage the sharing and dispatch.  In that
case SBFile was a unique_ptr<File>.
(here: https://github.com/smoofra/llvm-project/tree/files)

However in review, Pavel Labath suggested that it be shared_ptr instead.
(here: https://reviews.llvm.org/D67793)

In order for SBFile to use shared_ptr<File>, everything else should
as well.

If this patch is accepted, I will make SBFile use a shared_ptr
I will remove FileOps from future patches and use subclasses of File
instead.

Lawrence D'Anna 2fce1137c7 Convert FileSystem::Open() to return Expected<FileUP>
Summary:
This patch converts FileSystem::Open from this prototype:

Status
Open(File &File, const FileSpec &file_spec, ...);

to this one:

llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);

This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status.  It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.
