This test constructs an invalid std::string by starting with a null
pointer.
Somehow this improvement in Clang uncovered a bug in the formatter.
Perhaps because we now know the type of the field we tried to access is
char *, so fall back to a C string formatter that produces `(null)`.
The formatter tries to access `_M_p` and checked whether the resulting
ValueObjectSP was null, but not that it did not contain an error value.
I think that error value can be there if you are able to access one part
of the path, `_M_dataplus`, but another part fails. Since the layout
looks like this:
```
struct _Alloc_hider :
{
pointer _M_p; // The actual data.
};
_Alloc_hider _M_dataplus;
void
_M_data(pointer __p)
{ _M_dataplus._M_p = __p; }
```
So I think we were able to read `_M_dataplus` just by offset, but then
failed because it contains, or points to something containing nulls or a
null pointer.
Or perhaps an error value means we know what the class member is, but
could not read from it.
I found this by comparing with the libcxx formatter, so I've copied the
same handling from there to fix the issue.

This PR converts the `std::variant` summary from Python to C++.
Split from #148554. MSVC's STL and libstdc++ use the same type name for
`std::variant`, thus they need one "dispatcher" function that checks the
type and calls the appropriate summary. For summaries, both need to be
implemented in C++.
This is mostly a 1:1 translation. The main difference is that in C++,
the summary returns `false` if it can't inspect the object properly
(e.g. a member could not be found). In Python, this wasn't possible.

std::shared_ptr formatters (#147340)
Follow-up to
https://github.com/llvm/llvm-project/pull/147165#pullrequestreview-2992585513
Currently when we explicitly dereference a std::shared_ptr, both the
libstdc++ and libc++ formatters will cast the type of the synthetic
pointer child to whatever the `std::shared_ptr::element_type` is aliased
to. E.g.,
```
(lldb) v p
(std::shared_ptr<int>) p = 10 strong=1 weak=0 {
pointer = 0x000000010016c6a0
}
(lldb) v *p
(int) *p = 10
```
However, when we print (or dereference) `p.pointer`, the type devolves
to something less user-friendly:
```
(lldb) v p.pointer
(std::shared_ptr<int>::element_type *) p.pointer = 0x000000010016c6a0
(lldb) v *p.pointer
(std::shared_ptr<int>::element_type) *p.pointer = 10
```
This patch changes both formatters to store the casted type. Then
`GetChildAtIndex` will consistently use the unwrapped type.

summary (#147166)
Depends on https://github.com/llvm/llvm-project/pull/147165
This adds weak/strong counts to the std::shared_ptr summary of the
libstdcxx formatters. We already do this for libcxx. This will make it
easier to consolidate the tests into a generic one (see
https://github.com/llvm/llvm-project/pull/147141).

consistent with each other (#147165)
This patch adjusts the libcxx and libstdcxx std::shared_ptr formatters
to look the same.
Changes to libcxx:
* Now creates a synthetic child called `pointer` (like we already do for
`std::unique_ptr`)
Changes to libstdcxx:
* When asked to dereference the pointer, cast the type of the result
ValueObject to the element type (which we get from the template argument
to std::shared_ptr).
Before:
```
(std::__shared_ptr<int, __gnu_cxx::_S_atomic>::element_type) *foo = 123
```
After:
```
(int) *foo = 123
```
Tested in https://github.com/llvm/llvm-project/pull/147141

From #143177. This combines the summaries for the pre- and post C++ 11
`std::string` as well as `std::wstring`. In all cases, the data pointer
is reachable through `_M_dataplus._M_p`. It has the correct type (i.e.
`char*`/`wchar_t*`) and it's null terminated, so LLDB knows how to
format it as expected when using `GetSummaryAsCString`.
|
|
The problem was in calling GetLoadAddress on a value in the error state,
where `ValueObject::GetLoadAddress` could end up accessing the
uninitialized "address type" by-ref return value from `GetAddressOf`.
This probably happened because each function expected the other to
initialize it.
We can guarantee initialization by turning this into a proper return
value.
I've added a test, but it only (reliably) crashes if lldb is built with
ubsan.
|
|
When inspecting/printing types from MSVC's STL, LLDB would crash because
it assumes these types were from libstdc++. Specifically,
`std::shared_ptr` and `std::optional` would crash because of a null
pointer dereference. I added a minimal test that tests the types with
C++ helpers for libstdc++ (only tests for crashes).
- Fixes #115216
- Fixes #120310
This still has one unresolved discussion: What about MS STL types? This
is https://github.com/llvm/llvm-project/issues/24834, but there was a
bit of discussion in #120310 as well. The main issue is that MSVC's STL
uses the same type names as libstdc++ (i.e. neither uses an inline
namespace like libc++ for some types).

This patch pushes the error handling boundary for the GetBitSize()
methods from Runtime into the Type and CompilerType APIs. This makes it
easier to diagnose problems thanks to more meaningful error messages
being available. GetBitSize() is often the first thing LLDB asks about a
type, so this method is particularly important for a better user
experience.

The vast majority of `SyntheticChildrenFrontEnd` subclasses provide
children, and as such implement `MightHaveChildren` with a constant
value of `true`. This change makes `true` the default value. With this
change, `MightHaveChildren` only needs to be implemented by synthetic
providers that can return `false`, which is only 3 subclasses.

ValueObject is part of lldbCore for historical reasons, but conceptually
it deserves to be its own library. This does introduce a (link-time) circular
dependency between lldbCore and lldbValueObject, which is unfortunate
but probably unavoidable because so many things in LLDB rely on
ValueObject. We already have cycles and these libraries are never built
as dylibs so while this doesn't improve the situation, it also doesn't
make things worse.
The header includes were updated with the following command:
```
find . -type f -exec sed -i.bak "s%include \"lldb/Core/ValueObject%include \"lldb/ValueObject/ValueObject%" '{}' \;

(#67069)
We noticed some performance issue while in lldb-vscode for grabing the
name of the SBValue. Profiling shows SBValue::GetName() can cause
synthetic children provider of shared/unique_ptr to deference underlying
object and complete it type.
This patch lazily moves the dereference from synthetic child provider's
Update() method to GetChildAtIndex() so that SBValue::GetName() won't
trigger the slow code path.
Here is the culprit slow code path:

formatter
This mimicks the implementation of the libstdcpp std::unique_ptr
formatter.
This has been attempted several years ago in
`0789722d85cf1f1fdbe2ffb2245ea0ba034a9f94` but was reverted in
`e7dd3972094c2f2fb42dc9d4d5344e54a431e2ce`.
The difference to the original patch is that we now maintain
a `$$dereference$$` member and we only store weak pointers
to the other children inside the synthetic frontend. This is
what the libc++ formatters do to prevent the recursion mentioned
in the revert commit.

started
The StringPrinter class was using a Process instance to read memory.
This automatically prevented it from working before starting the
program.
This patch changes the class to use the Target object for reading
memory, as targets are always available. This required moving
ReadStringFromMemory from Process to Target.
This is sufficient to make frame/target variable work, but further
changes are necessary for the expression evaluator. Preliminary analysis
indicates the failures are due to the expression result ValueObjects
failing to provide an address, presumably because we're operating on
file addresses before starting. I haven't looked into what would it take
to make that work.

(This is D68010 but I also set the new parameter in LibStdcpp.cpp to fix
the Debian tests).
Summary:
Printing a summary for an empty NSPathStore2 string currently prints random bytes behind the empty string pointer from memory (rdar://55575888).
It seems the reason for this is that the SourceSize parameter in the `ReadStringAndDumpToStreamOptions` - which is supposed to contain the string
length - actually uses the length 0 as a magic value for saying "read as much as possible from the buffer" which is clearly wrong for empty strings.
This patch adds another flag that indicates if we have know the string length or not and makes this behaviour dependent on that (which seemingly
was the original purpose of this magic value).

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Summary:
This commit renames ClangASTContext to TypeSystemClang to better reflect what this class is actually supposed to do
(implement the TypeSystem interface for Clang). It also gets rid of the very confusing situation that we have both a
`clang::ASTContext` and a `ClangASTContext` in clang (which sometimes causes Clang people to think I'm fiddling
with Clang's ASTContext when I'm actually just doing LLDB work).
I also have plans to potentially have multiple clang::ASTContext instances associated with one ClangASTContext so
the ASTContext naming will then become even more confusing to people.

Summary:
When we want to compare a ConstString against a string literal (or any other non-ConstString),
we currently have to explicitly turn the other string into a ConstString. This makes sense as
comparing ConstStrings against each other is only a fast pointer comparison.
However, currently we (rather incorrectly) use in several places in LLDB temporary ConstStrings when
we just want to compare a given ConstString against a hardcoded value, for example like this:
```
if (extension != ConstString(".oat") && extension != ConstString(".odex"))
```
Obviously this kind of defeats the point of ConstStrings. In the comparison above we would
construct two temporary ConstStrings every time we hit the given code. Constructing a
ConstString is relatively expensive: we need to go to the StringPool, take a read and possibly
an exclusive write-lock and then look up our temporary string in the string map of the pool.
So we do a lot of heavy work for essentially just comparing a <6 characters in two strings.
I initially wanted to just fix these issues by turning the temporary ConstString in static variables/
members, but that made the code much less readable. Instead I propose to add a new overload
for the ConstString comparison operator that takes a StringRef. This comparison operator directly
compares the ConstString content against the given StringRef without turning the StringRef into
a ConstString.
This means that the example above can look like this now:
```
if (extension != ".oat" && extension != ".odex")
```
It also no longer has to unlock/lock two locks and call multiple functions in other TUs for constructing
the temporary ConstString instances. Instead this should end up just being a direct string comparison
of the two given strings on most compilers.
This patch also directly updates all uses of temporary and short ConstStrings in LLDB to use this new
comparison operator. It also adds a some unit tests for the new and old comparison operator.

My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.
ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

Essentially, all code in the project is now made available by the LLVM

The code in LLDB assumes that CompilerType and friends use the size 0
as a sentinel value to signal an error. This works for C++, where no
zero-sized type exists, but in many other programming languages
(including I believe C) types of size zero are possible and even
common. This is a particular pain point in swift-lldb, where extra
code exists to double-check that a type is *really* of size zero and
not an error at various locations.
To remedy this situation, this patch starts by converting
CompilerType::getBitSize() and getByteSize() to return an optional
result. To avoid wasting space, I hand-rolled my own optional data
type assuming that no type is larger than what fits into 63
bits. Follow-up patches would make similar changes to the ValueObject
hierarchy.

Summary:
Despite it's name, GetTemplateArgument was only really working for Type
template arguments. This adds the ability to retrieve integral arguments
as well (which I've needed for the std::bitset data formatter).
I've done this by splitting the function into three pieces. The idea is
that one first calls GetTemplateArgumentKind (first function) to
determine the what kind of a parameter this is. Based on that, one can
then use specialized functions to retrieve the correct value. Currently,
I only implement two of these: GetTypeTemplateArgument and
GetIntegralTemplateArgument.

This renames the LLDB error class to Status, as discussed

A change of this magnitude cannot easily be done without

was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

TestPrintStackTraces (funnily enough, only when logging is enabled).

*** 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.
