Python's internal stderr may differ from sys.stderr.
When Python writes errors, it uses its internal stderr rather than the
overwritten sys.stderr.
This may not be the same file/handle
Fix the test to explicitly write to the specified stderr.

returns the correct value also for "_BitInt(...)" types. (#165857)
When trying to get the `SBType` object corresponding to the
`_BitInt(...)` type name, we have noticed that the
`SBTarget::FindFirstType` metod returns `nil`. This branch proposes:
- some test that demonstrate that the problem exists
- a possible fix

Implements part of #168920

Consider the following program:
```
int main() {
int foo[2][3][4];
int (*bar)[3][4] = foo;
return 0;
}
```
If we:
- compile this program
- launch an LLDB debugging session
- launch the process and let it stop at the `return 0;` statement
then the following LLDB command:
```
(lldb) script lldb.frame.FindVariable("bar").GetChildAtIndex(0).get_expr_path()
```
will produce the following output:
```
bar->[0]
```
What we were expecting:
- a valid expression in the C programming language
- that would allow us (in the scope of the `main` function) access the
appropriate object.
What we've got is a string that does not represent a valid expression in
the C programming language.
This pull-request proposes a fix to this problem.

There is no indication this ever worked on windows as this is the first
test that checks python interactive console from a file.
Looking at the error from the CI, It closed the interpreter before
running any python commands.
Will reconfirm this when I have access to a windows machine.

The cause is that in `python3.14`, `fcntl.ioctl` now throws a buffer
overflow error
when the buffer is too small or too large (see
https://github.com/python/cpython/pull/132919). This caused the Python
interpreter to fail terminal detection and not properly echo user
commands back to the screen.
Fix by dropping the custom terminal size check entirely and using the
built-in `sys.stdin.isatty()` instead.
Fixes #173302

I know this is required for at least one feature, because
TestSectionAPI.py has failures if zlib isn't enabled. So I think it's
useful for users to be able to check.
Now that it's in the config, I have also used it to make a test
annotation so we don't get the failure in TestSectionAPI.py when zlib is
disabled.
Which for future reference was:

ranges (#158811)
Scripted frames that materialize Python functions are PC-less by design,
meaning they don't have valid address ranges. Previously,
LineEntry::IsValid()
required both a valid address range and a line number, preventing
scripted
frames from creating valid line entries for these synthetic stack
frames.
Relaxing this requirement is necessary since
`SBSymbolContext::SetLineEntry`
will first check if the LineEntry is valid and discard it otherwise.
This change introduces an `synthetic` flag that gets set when LineEntry
objects are created or modified through the SBAPI (specifically via
SetLine).
When this flag is set, IsValid() no longer requires a valid address
range,
only a valid line number.
This is risk-free because the flag is only set for LineEntry objects
created
through the SBAPI, which are primarily used by scripted processes and
frames.
Regular debug information-derived line entries continue to require valid
address ranges.

Recently I've been deep diving ELF cores in LLDB, aspiring to move LLDB
closer to GDB in capability. One issue I encountered was a system lib
losing it's unwind plan when loading the debuginfo. The reason for this
was the debuginfo has the eh_frame section stripped and the main
executable did not.
The root cause of this was this line in
[ObjectFileElf](https://github.com/llvm/llvm-project/blob/163933e9e7099f352ff8df1973f9a9c3d7def6c5/lldb/source/Plugins/ObjectFile/ELF/ObjectFileELF.cpp#L1972)
```
// For eTypeDebugInfo files, the Symbol Vendor will take care of updating the
// unified section list.
if (GetType() != eTypeDebugInfo)
unified_section_list = *m_sections_up;
```
This would always be executed because CalculateType can never return an
eTypeDebugInfo
```
ObjectFile::Type ObjectFileELF::CalculateType() {
switch (m_header.e_type) {
case llvm::ELF::ET_NONE:
// 0 - No file type
return eTypeUnknown;
case llvm::ELF::ET_REL:
// 1 - Relocatable file
return eTypeObjectFile;
case llvm::ELF::ET_EXEC:
// 2 - Executable file
return eTypeExecutable;
case llvm::ELF::ET_DYN:
// 3 - Shared object file
return eTypeSharedLibrary;
case ET_CORE:
// 4 - Core file
return eTypeCoreFile;
default:
break;
}
return eTypeUnknown;
}
```
This makes sense as there isn't a explicit sh_type to denote that this
file is a debuginfo. After some discussion with @clayborg and
@GeorgeHuyubo we settled on joining the exciting unified section list
with whatever new sections were being added. Adding each new unique
section, or taking the section with the maximum file size. We picked
this strategy to pick the section with the most information. In most
scenarios, LHS should be SHT_NOBITS and RHS would be SHT_PROGBITS.
Here is a diagram documenting the existing vs proposed new way.

This patch introduces `SBFrameList`, a new SBAPI class that allows
iterating over stack frames lazily without calling
`SBThread::GetFrameAtIndex` in a loop.
The new `SBThread::GetFrames()` method returns an `SBFrameList` that
supports Python iteration (`for frame in frame_list:`), indexing
(`frame_list[0]`, `frame_list[-1]`), and length queries (`len()`).
The implementation uses `StackFrameListSP` as the opaque pointer,
sharing the thread's underlying frame list to ensure frames are
materialized on-demand.
This is particularly useful for ScriptedFrameProviders, where user
scripts will be to iterate, filter, and replace frames lazily without
materializing the entire stack upfront.

the function signature for `GetStopDescription` is
`lldb::SBThread::GetStopDescription(char *dst_or_null, size_t len)`.
To get a description you need to call the function first time to get the
buffer size. a second time to get the description.
This is little worse from the python size as the signature is
`lldb.SBThread.GetStopDescription(int: len) -> list[str]` the user has
to pass the max size as possible with no way of checking if it is
enough.
This patch adds a new api
`lldb.SBThread.GetStopDescription(desc: lldb.SBStream()) -> bool` `bool
lldb::SBThread::GetStopDescription(lldb::SBStream &description)` which
handles this case.
Adds new Test case for lua.

(#162278)
When we take the following C program:
```
int main() {
return 0;
}
```
and create a statically-linked executable from it:
```
clang -static -g -o main main.c
```
Then we can observe the following `lldb` behavior:
```
$ lldb
(lldb) target create main
Current executable set to '.../main' (x86_64).
(lldb) breakpoint set --name main
Breakpoint 1: where = main`main + 11 at main.c:2:3, address = 0x000000000022aa7b
(lldb) process launch
Process 3773637 launched: '/home/me/tmp/built-in/main' (x86_64)
Process 3773637 stopped
* thread #1, name = 'main', stop reason = breakpoint 1.1
frame #0: 0x000000000022aa7b main`main at main.c:2:3
1 int main() {
-> 2 return 0;
3 }
(lldb) script lldb.debugger.GetSelectedTarget().FindFirstType("__int128").size
0
(lldb) script lldb.debugger.GetSelectedTarget().FindFirstType("unsigned __int128").size
0
(lldb) quit
```
The value return by the `SBTarget::FindFirstType` method is wrong for
the `__int128` and `unsigned __int128` basic types.
The proposed changes make the `TypeSystemClang::GetBasicTypeEnumeration`
method consistent with `gcc` and `clang` C [language
extension](https://gcc.gnu.org/onlinedocs/gcc/_005f_005fint128.html)
related to 128-bit integer types as well as with the
`BuiltinType::getName` method in the LLVM codebase itself.
When the above change is applied, the behavior of the `lldb` changes in
the following (desired) way:
```
$ lldb
(lldb) target create main
Current executable set to '.../main' (x86_64).
(lldb) breakpoint set --name main
Breakpoint 1: where = main`main + 11 at main.c:2:3, address = 0x000000000022aa7b
(lldb) process launch
Process 3773637 launched: '/home/me/tmp/built-in/main' (x86_64)
Process 3773637 stopped
* thread #1, name = 'main', stop reason = breakpoint 1.1
frame #0: 0x000000000022aa7b main`main at main.c:2:3
1 int main() {
-> 2 return 0;
3 }
(lldb) script lldb.debugger.GetSelectedTarget().FindFirstType("__int128").size
16
(lldb) script lldb.debugger.GetSelectedTarget().FindFirstType("unsigned __int128").size

for expression evaluation (#161688)
Depends on:
* https://github.com/llvm/llvm-project/pull/162050
Since it's a 'Note' diagnostic it would only show up when expression
evaluation actually failed. This helps with expression evaluation
failure reports in mixed language environments where it's not quite
clear what language the expression ran as. It may also reduce confusion
around why the expression evaluator ran an expression in a language it
wasn't asked to run (a softer alternative to what I attempted in
https://github.com/llvm/llvm-project/pull/156648).
Here are some example outputs:
```
# Without target
(lldb) expr blah
note: Falling back to default language. Ran expression as 'Objective C++'.
# Stopped in target
(lldb) expr blah
note: Ran expression as 'C++14'.
(lldb) expr -l objc -- blah
note: Expression evaluation in pure Objective-C not supported. Ran expression as 'Objective C++'.
(lldb) expr -l c -- blah
note: Expression evaluation in pure C not supported. Ran expression as 'ISO C++'.
(lldb) expr -l c++14 -- blah
note: Ran expression as 'C++14'
(lldb) expr -l c++20 -- blah
note: Ran expression as 'C++20'
(lldb) expr -l objective-c++ -- blah
note: Ran expression as 'Objective C++'
(lldb) expr -l D -- blah
note: Expression evaluation in D not supported. Falling back to default language. Ran expression as 'Objective C++'.
```
I didn't put the diagnostic on the same line as the inline diagnostic
for now because of implementation convenience, but if reviewers deem
that a blocker I can take a stab at that again.
Also, other language plugins (namely Swift), won't immediately benefit
from this and will have to emit their own diagnistc. I played around
with having a virtual API on `UserExpression` or `ExpressionParser` that
will be called consistently, but by the time we're about to parse the
expression we are already several frames deep into the plugin. Before
(and at the beginning of) the generic `UserExpression::Parse` call we
don't have enough information to notify which language we're going to
parse in (at least for the C++ plugin).

### Summary
Add support for unique target ids per Target instance. This is needed
for upcoming changes to allow debugger instances to be shared across
separate DAP instances for child process debugging. We want the IDE to
be able to attach to existing targets in an already runny lldb-dap
session, and having a unique ID per target would make that easier.
Each Target instance will have its own unique id, and uses a
function-local counter in `TargetList::CreateTargetInternal` to assign
incremental unique ids.
### Tests
Added several unit tests to test basic functionality, uniqueness of
targets, and target deletion doesn't affect the uniqueness.
```
bin/lldb-dotest -p TestDebuggerAPI

The LLVM Style Guide says the following about error and warning messages
[1]:
> [T]o match error message styles commonly produced by other tools,
> start the first sentence with a lowercase letter, and finish the last

I often provide this feedback during code review, but we still have a
bunch of places where we have inconsistent error message, which bothers
me as a user. This PR identifies a handful of those places and updates
the messages to be consistent.

When you are trying for instance to set a breakpoint on a function by
name, but the SBFunction or SBSymbol are returning demangled names with
argument lists, that match can be tedious to do. Internally, the base
name of a symbol is something we handle all the time, so it's reasonable
that there should be a way to get that info from the API as well.

[lldb] Rename RecursiveDecentFormatter to RecursiveDescentFormatter (NFC)
|
|
`GetHeapRanges()` could return two overlapping ranges because it did not
check whether `heap_pointer1` lies within the range returned for
`heap_pointer2`. This could result in a test failure in
`test_find_ranges_in_memory_two_matches` when
`process.FindRangesInMemory()` returned 3 instead of 2.
The patch ensures that `GetHeapRanges()` returns either two
non-overlapping ranges or one range covering both heap pointers.
The issue was probably introduced in #111951
|
|
Prior to this patch, SBFrame/SBThread methods exhibit racy behavior if
called while the process is running, because they do not lock the
`Process::RetRunLock` mutex. If they did, they would fail, correctly
identifying that the process is not running.
Some methods _attempt_ to protect against this with the pattern:
```
ExecutionContext exe_ctx(m_opaque_sp.get(), lock); // this is a different lock
Process *process = exe_ctx.GetProcessPtr();
if (process) {
Process::StopLocker stop_locker;
if (stop_locker.TryLock(&process->GetRunLock()))
.... do work ...
```
However, this is also racy: the constructor of `ExecutionContext` will
access the frame list, which is something that can only be done once the
process is stopped.
With this patch:
1. The constructor of `ExecutionContext` now expects a `ProcessRunLock`
as an argument. It attempts to lock the run lock, and only fills in
information about frames and threads if the lock can be acquired.
Callers of the constructor are expected to check the lock.
2. All uses of ExecutionContext are adjusted to conform to the above.
3. The SBThread.cpp-defined helper function ResumeNewPlan now expects a
locked ProcessRunLock as _proof_ that the execution is stopped. It will
unlock the mutex prior to resuming the process.
This commit exposes many opportunities for early-returns, but these
would increase the diff of this patch and distract from the important
changes, so we opt not to do it here.

`SBType::GetBasicType` fails on typedefs to primitive types. The docs
for `GetBasicType` state:
```
Returns the BasicType value that is most appropriate to this type
```
But, e.g., for `uint64_t` this would currently return
`eBasicTypeInvalid`.
`TypeSystemClang::GetBasicTypeEnumeration` (which is what
`SBType::GetBasicType` uses) doesn't see through typedefs. Inside LLDB
we almost always call `GetBasicTypeEnumeration` on the canonical type.
In the cases we don't I suspect those were just subtle bugs. This patch
gets the canonical type inside of `GetBasicTypeEnumeration` instead.

### Context
Over a year ago, I landed support for 64b Memory ranges in Minidump
(#95312). In this patch we added the Memory64 list stream, which is
effectively a Linked List on disk. The layout is a sixteen byte header
and then however many Memory descriptors.
### The Bug
This is a classic off-by one error, where I added 8 bytes instead of 16
for the header. This caused the first region to start 8 bytes before the
correct RVA, thus shifting all memory reads by 8 bytes. We are correctly
writing all the regions to disk correctly, with no physical corruption
but the RVA is defined wrong, meaning we were incorrectly reading memory
### Why wasn't this caught?
One problem we've had is forcing Minidump to actually use the 64b mode,
it would be a massive waste of resources to have a test that actually
wrote >4.2gb of IO to validate the 64b regions, and so almost all
validation has been manual. As a weakness of manual testing, this issue
is psuedo non-deterministic, as what regions end up in 64b or 32b is
handled greedily and iterated in the order it's laid out in
/proc/pid/maps. We often validated 64b was written correctly by
hexdumping the Minidump itself, which was not corrupted (other than the
BaseRVA)
### Why is this showing up now?
During internal usage, we had a bug report that the Minidump wasn't
displaying values. I was unable to repro the issue, but during my
investigation I saw the variables were in the 64b regions which resulted
in me identifying the bug.
### How do we prevent future regressions?
To prevent regressions, and honestly to save my sanity for figuring out
where 8 bytes magically came from, I've added a new API to
SBSaveCoreOptions.
```SBSaveCoreOptions::GetMemoryRegionsToSave()```
The ability to get the memory regions that we intend to include in the Coredump. I added this so we can compare what we intended to include versus what was actually included. Traditionally we've always had issues comparing regions because Minidump includes `/proc/pid/maps` and it can be difficult to know what memoryregion read failure was a genuine error or just a page that wasn't meant to be included.
We are also leveraging this API to choose the memory regions to be generated, as well as for testing what regions should be bytewise 1:1.
After much debate with @clayborg, I've moved all non-stack memory to the Memory64 List. This list doesn't incur us any meaningful overhead and Greg originally suggested doing this in the original 64b PR. This also means we're exercising the 64b path every single time we save a Minidump, preventing regressions on this feature from slipping through testing in the future.

### Misc
As a part of this fix I had to look at LLDB logs a lot, you'll notice I added `0x` to many of the PRIx64 `LLDB_LOGF`. This is so the user (or I) can directly copy paste the address in the logs instead of adding the hex prefix themselves.
Added some SBSaveCore tests for the new GetMemoryAPI, and Docstrings.
CC: @DavidSpickett, @da-viper @labath because we've been working together on save-core plugins, review it optional and I didn't tag you but figured you'd want to know

Since https://github.com/llvm/llvm-project/pull/148691 enabled
exceptions when compiling the tests, this test has been failing.
Much like was noted there, one of the variables disappeared
from the debug info. Giving it a non-zero size and initialising
it fixed that.

This PR adds type summaries for
`std::{string,wstring,u8string,u16string,u32string}` from the MSVC STL.
See https://github.com/llvm/llvm-project/issues/24834 for the MSVC STL
issue.
The following changes were made:
- `dotest.py` now detects if the MSVC STL is available. It does so by
looking at the target triple, which is an additional argument passed
from Lit. It specifically checks for `windows-msvc` to not match on
`windows-gnu` (i.e. MinGW/Cygwin).
- (The main part): Added support for summarizing `std::(w)string` from
MSVC's STL. Because the type names from the libstdc++ (pre C++ 11)
string types are the same as on MSVC's STL, `CXXCompositeSummaryFormat`
is used with two entries, one for MSVC's STL and one for libstdc++.
With MSVC's STL, `std::u{8,16,32}string` is also handled. These aren't
handled for libstdc++, so I put them in `LoadMsvcStlFormatters`.

Add a class property for the version string. This allows you to use
access the version string through `lldb.SBDebugger.version` instead of
having to call `lldb.SBDebugger.GetVersionString()`.

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.

The architectures provided to skipIf / expectedFail are regular
expressions (v. _match_decorator_property() in decorators.py
so on Darwin systems "arm64" would match the skips for "arm" (32-bit
Linux). Update these to "arm$" to prevent this, and also update
three tests (TestBuiltinFormats.py, TestCrossDSOTailCalls.py,
TestCrossObjectTailCalls.py) that were skipped for arm64 via this
behavior, and need to be skipped or they will fail.
This was moviated by the new TestDynamicValue.py test which has
an expected-fail for arm, but the test was passing on arm64 Darwin
resulting in failure for the CIs.

Same purpose as https://github.com/llvm/llvm-project/pull/141407,
comitting this directly to get the bot green sooner.

* Changes the default synthetic symbol names to contain their file
address
This is a new PR after the first PR (#137512) was reverted because it
didn't update the way unnamed symbols were searched in the symbol table,
which relied on the index being in the name.
This time also added extra test to make sure the symbol is found as
expected

The motivation here is being (un)able to treat pointer values as an
array consistently. This works for pointers to simple/scalar values, but
for aggregates, we get a very surprising result:
- GetChildAtIndex(x, ??, true) returns the `x` child of the zeroth array
member (the one you get by dereferencing the pointer/array) for all `x`
which are smaller than the number of children of that value.
- for other values of `x`, we get `v[x]`, where `v` is treated like a
(C) pointer
This patch reimagines this interface so that the value of `true` always
treats (pointer and array) values as pointers. For `false`, we always
dereference pointers, while in the case of arrays, we only return the
values as far as the array bounds will allow.
This has the potential to break existing code, but I have a suspicion
that code was already broken to begin with, which is why I think this
would be better than introducing a new API and keeping the old (and
surprising) behavior. If our own test coverage is any indication,
breakage should be minimal.

test_common is force-included into every compilation, which causes
problems when we're compiling assembly code, as we were in #138805.
This avoids that as we can include the header only when it's needed.
