This skips some tests that pass with active replay (which doesn't check
the output) but fail with passive replay. Valid reasons for this
include:
- Checking the output of the process (which doesn't run during replay),
- Checking files that cannot be captured in the VFS (non-existing or
unreadable files or files that are removed during test),
Unfortunately there's no good way to mark a test as supported for active
replay but unsupported for passive replay because the number and order
of API calls needs to be identical during capture and replay. I don't
think this is a huge loss however.
All entry points into ProcessGDBRemote that connect to the debug server
should connect to the replay server instead during reproducer replay.
This patch adds the necessary logic for ConnectRemote, which is
accessible from the SB API. This fixes active replay for
TestRecognizeBreakpoint.py as described in D78588.
Summary:
1. Created a new common completion for the registers of the current context;
2. Apply this new common completion to the commands register read/write;
3. Unit test.

We currently rely on the TypeSystem implementation to initialize this value
with 0 in the GetChildCompilerTypeAtIndex call below. Let's just initialize
this variable like the rest.
The source file used to test Objective-C data-formatters didn't respected
any formatting (mixed tab and spaces, lines exceed column 80, etc...).
This patch reformats the file using clang-format to make it easier to
work with.

For Swift LLDB (but potentially also for module support in Clang-land)
we need a way to accumulate the path remappings produced by
Module::RegisterXcodeSDK(). In order to make this work for
SymbolFileDebugMaps, registering the search path remapping with both
modules is necessary.

The Python used to run lit can be different from the Python LLDB was
build with. One scenario where this happens is when LLVM can find the
Python 3 interpreter, but not the Python 3 libraries, in which case LLDB
build and links against Python 3. Without this change, you end up with
an ModuleNotFoundError because of the mismatch.
Instead of looking at the Python interpreter that's used to run lit,
lldbtest should use the interpreter that matches the Python version LLDB
was build against.

When debugging from a SymbolMap the creation of CompileUnits for the
individual object files is so lazy that RegisterXcodeSDK() is not
invoked at all before the Swift TypeSystem wants to read it. This
patch fixes this by introducing an explicit
SymbolFile::ParseXcodeSDK() call that can be invoked deterministically
before the result is required.

Summary:
Sometimes users think that setting a function regex for all function that contain the word 'needle' in their
name looks like this: `*needle*`. However, LLDB only searches the function name and doesn't fully match
it against the regex, so the leading and trailing '*' operators don't do anything and actually just cause the
regex engine to reject the regular expression with "repetition-operator operand invalid".
This patch makes this a bit more obvious to the user by printing a warning that a leading '*' before this
regular expression here doesn't have any purpose (and will cause an error). This doesn't attempt to detect
a case where there is only a trailing '*' as that would involve parsing the regex and it seems the most
common way to end up in this situation is by doing `rbreak *needle*`.

Summary:
This fixes a bug where
frame var a[0]+5
returns the value a[0] without any warning because the current logic simply ignores everything after ']' as long as there is no '.', '-' or '[' in the rest of the string.
The fix simplifies the termination condition of the expression path parsing loop to check if have a non-empty remaining string to parse. Previously, the condition checked if a separator was found. That condition coincided with the remaining string-to-parse condition except for the buggy indexed case where non-empty string was left ("+5" in the example above), but the separator index was 'npos'.

After 61d5b0e663 more shell test are expected to exit with a non-zero
status code. Because the exit status is computed in the driver and not
behind the SB API layer, reproducers don't know about it and always
return 0 unless replay failed.
This discrepancy means that these tests don't work with lldb-repro.py
and skipping them for this reason would be a pity. To solve this
problem, the script now serializes the exit code during capture and
returns that during replay.
These is an assert that ensures that replay exits with a zero exit
status to prevent replay failures from being silently ignored.
Update CallBoardSystemServiceOpenApplication to unconditionally log
the NSError's localizedDescription to Console on app launch failure
(as it was already doing), and also to log the NSError object's
full description to the console, which may contain additional nested
error messages. I'm experimenting to find cases where we will get
more detailed information from app launch failures and will start
by logging both to the console.

It looks like the new implementation is correct, since there were TODOs
here about getting the new behavior.
I am not sure if "C:..\.." should become "C:" or "C:\", though. The new
output doesn't precisely match the TODO message, but it seems
appropriate given the specification of remove_dots and how .. traversals
work at the root directory.
Summary:
Languages can have different ways of formatting special characters.
E.g. when debugging C++ code a string might look like "\b", but when
debugging Swift code the same string would look like "\u{8}".
To make this work, plugins override GetStringPrinterEscapingHelper.
However, because there's a large amount of subtly divergent work done in
each override, we end up with large amounts of duplicated code. And all
the memory smashers fixed in one copy of the logic (see D73860) don't
get fixed in the others.
IMO the GetStringPrinterEscapingHelper is overly general and hard to
use. I propose deleting it and replacing it with an EscapeStyle enum,
which can be set as needed by each plugin.
A fix for some swift-lldb memory smashers falls out fairly naturally
from this deletion (https://github.com/apple/llvm-project/pull/1046). As
the swift logic becomes really tiny, I propose moving it upstream as
part of this change. I've added unit tests to cover it.

When trying to read a core file that is not owned by the user running lldb
and that doesn't have read permission on the file, lldb shows a misleading
error message:
```
Unable to find process plug-in for core file
```
This is due to the fact that currently, lldb doesn't check the file
ownership. And when trying to to open and read a core file, the syscall
fails, which prevents a process to be created.
Since lldb already have a portable `open` syscall interface, lets take
advantage of that and delegate the error handling to the syscall
itself. This way, no matter if the file exists or if the user has proper
ownership, lldb will always try to open the file, and behave accordingly
to the error code returned.

The dumping code is not used by anyone, and is a source of
inconsistencies with the llvm dwarf parser, as dumping is implemented at
a different level (DWARFDie) there.
This adds an RunCommandInterpreter overload that returns an instance of

This patch adds a new class CommandInterpreterRunResult which will be
backing the SBCommandInterpreterRunResult. It keeps track of the number
of errors as well as the result which is an enum, as proposed by Pavel

instead of its own member variables.

Currently, `SBCommandInterpreterRunOptions` is defined in
`SBCommandInterpreter.h`. Given that the options are always passed by
reference, a forward declaration is sufficient.
That's not the case for `SBCommandInterpreterRunResults`, which we need
for a new overload for `RunCommandInterpreter` and that returns this new
class by value. We can't include `SBCommandInterpreter.h` because
`SBCommandInterpreter::GetDebugger()` returns SBDebugger by value and
therefore needs a full definition.
This patch moves the definition of `SBCommandInterpreterRunOptions` into
a new header. In a later patch, `SBCommandInterpreterRunResults` will
be defined in there as well, solving the aforementioned problem.

It seems like only the unittests are building with
BUILD_WITH_INSTALL_RPATH set to OFF. Of course when I did my last change
I only ran check-lldb-unit. Not sure why this difference exists, why
would you even install the unittest?
For the LLDB framework we do need different build and install RPATHs.
Currently that logic lives downstream. I plan to upstream that in the
near future. For now I'm just trying to make it possible to run the
test.

This was originally commented out as it broke the data-formatter-stl/libcxx/

The install name for the Python 3 framework in Xcode is relative to
the framework's location and not the dylib itself.
@rpath/Python3.framework/Versions/3.x/Python3
This means that we need to compute the path to the Python3.framework
and use that as the RPATH instead of the usual dylib's directory.
