The WatchAddress API includes a flag to indicate if watchpoint should be
for read, modify or both. This API uses 2 booleans, but the 'modify'
flag was ignored and WatchAddress unconditionally watched write
(actually modify).
We now only watch for modify when the modify flag is true.
---
The included test fails prior to this patch and succeeds after. That is
previously specifying `False` for `modify` would still stop on _write_,
but after the patch correctly only stops on _read_

Now that we store the command in the CommandReturnObject (#125132) we
can check the command in the print callback.

Xcode uses a pseudoterminal for the debugger console.
- The upside of this apporach is that it means that it can rely on
LLDB's IOHandlers for multiline and script input.
- The downside of this approach is that the command output is printed to
the PTY and you don't get a SBCommandReturnObject. Adrian added support
for inline diagnostics (#110901) and we'd like to access those from the
IDE.
This patch adds support for registering a callback in the command
interpreter that gives access to the `(SB)CommandReturnObject` right
before it will be printed. The callback implementation can choose
whether it likes to handle printing the result or defer to lldb. If the
callback indicated it handled the result, the command interpreter will
skip printing the result.
We considered a few other alternatives to solve this problem:
- The most obvious one is using `HandleCommand`, which returns a
`SBCommandReturnObject`. The problem with this approach is the multiline
input mentioned above. We would need a way to tell the IDE that it
should expect multiline input, which isn't known until LLDB starts
handling the command.
- To address the multiline issue,we considered exposing (some of the)
IOHandler machinery through the SB API. To solve this particular issue,
that would require reimplementing a ton of logic that already exists
today in the CommandInterpeter. Furthermore that seems like overkill
compared to the proposed solution.

As suggested in #125006. Depending on which PR lands first, I'll update
`TestCommandInterepterPrintCallback.py` to check that the
`CommandReturnObject` passed to the callback has the correct command.

Recently I've been working on a lot of internal Python tooling, and in
certain cases I want to report async to the script over DAP. Progress.h
already handles this, so I've exposed Progress via the SB API so Python
scripts can also update progress objects.
I actually have no idea how to test this, so I just wrote a [toy command
to test
it](https://gist.github.com/Jlalond/48d85e75a91f7a137e3142e6a13d0947)
I also copied the first section of the extensive Progress.h class
documentation to the docstrings.

This patch adds the ability to get a thread at a give index, based on
insertion order, for SBSaveCore Options. This is primarily to benefit
scripts using SBSaveCore, and remove the need to have both options and a
second collection if your script is tracking what threads need to be
saved. Such as if you want to collect the source of all the threads to
be saved after the Core is generated.

Introduces a `member` property to `SBValue`. This property provides pythonic access to a
value's members, by name. The expression `value.member["name"]` will be an alternate
form form of writing `value.GetChildMemberWithName("name")`.

This PR fixes a simple SWIG issue with SBMemoryRegionInfoList not being
iterable out-of-the-box. This is mostly because of limitations to the
`lldb_iter` function, which doesn't allow for specifying arguments to
the size / iter functions passed.

API test failed for remote platform in
[#112657](https://github.com/llvm/llvm-project/pull/112657)
Previously when putting files onto remote platform, I used `platform
file write -d <data>` which actually required a `platform file open
<path>` first in order to obtain a file descriptor.
eg. in file
[TestGDBRemotePlatformFile.py](https://github.com/llvm/llvm-project/blob/94e7d9c0bfe517507ea08b00fb00c32fb2837a82/lldb/test/API/functionalities/gdb_remote_client/TestGDBRemotePlatformFile.py#L24-L32)
To fix this, use the `platform put-file` method, which is used in the
`redirect_stdin` from this test already.

configuration.dwarf_version (#114161)
The tests were using the variable directly to get the dwarf version used
for the test. That's only the overridden value, and won't be set if
we're using the compiler default. I also put a comment by the variable
to make sure people don't make the same mistake in the future.

When `FileAction` opens file with write access, it doesn't clear the
file nor append to the end of the file if it already exists. Instead, it
writes from cursor index 0.
For example, by using the settings `target.output-path` and
`target.error-path`, lldb will redirect process stdout/stderr to files.
It then calls this function to write to the files which the above
symptoms appear.
## Test
- Added unit test checking the file flags
- Added 2 api tests checking
- File content overwritten if the file path already exists
- Stdout and stderr redirection to the same file doesn't change its
behavior

A memory region can be relatively large. Searching for a value in the
entire region is time-consuming, especially when running tests against a
remote target, because the memory data is transferred in small chunks
over a relatively slow GDB Remote Protocol. The patch limits the address
range to be searched to 2K, which seems sufficient for these tests. In
my setup, for local runs, these tests now take half the time they did
before the patch. For a remote target, the improvement is even more
significant.

Line ending policies were changed in the parent, dccebddb3b80. To make
it easier to resolve downstream merge conflicts after line-ending
policies are adjusted this is a separate whitespace-only commit. If you
have merge conflicts as a result, you can simply `git add --renormalize
-u && git merge --continue` or `git add --renormalize -u && git rebase
--continue` - depending on your workflow.

`SBDebugger().Create()` returns a debugger with only the host platform
in its platform list. If the test suite is running for a remote
platform, it should be explicitly added and selected in the new debugger
created within the test, otherwise, the test will fail because the host
platform may not be able to launch the built binary.
|
|
The function should use the by-ref SBError argument instead of creating
a new one. This code has been here since ~forever, and was probably
copied from methods which return an SBError result (where one needs to
create a local variable).
|
|
This fix is based on a problem with cxx_compiler and cxx_linker macros
on Windows.
There was an issue with compiler detection in paths containing "icc". In
such case, Makefile.rules thought it was provided with icc compiler.
To solve that, utilities detection has been rewritten in Python.
The last element of compiler's path is separated, taking into account
the platform path delimiter, and compiler type is extracted, with regard
of possible cross-toolchain prefix.

Reapply #100443 and #101770. These were originally reverted due to a
test failure and an MSAN failure. I changed the test attribute to
restrict to x86 (following the other existing tests). I could not
reproduce the test or the MSAN failure and no repo steps were provided.

(#100443)
In #98403 I enabled the SBSaveCoreOptions object, which allows users via
the scripting API to define what they want saved into their core file.
As the first option I've added a threadlist, so users can scan and
identify which threads and corresponding stacks they want to save.
In order to support this, I had to add a new method to `Process.h` on
how we identify which threads are to be saved, and I had to change the
book keeping in minidump to ensure we don't double save the stacks.
Important to @jasonmolenda I also changed the MachO coredump to accept
these new APIs.
|

overload (#98403)
This PR adds `SBSaveCoreOptions`, which is a container class for options
when LLDB is taking coredumps. For this first iteration this container
just keeps parity with the extant API of `file, style, plugin`. In the
future this options object can be extended to allow users to take a
subset of their core dumps.

A new file was added to the python_api/events test, but I forgot to
git add it before making the PR. The commit was:

This fixes a bug where Process events were being delivered to secondary
listeners when the Private state thread listener was processing the
event. That meant the secondary listener could get an event before the
Primary listener did. That in turn meant the state when the secondary
listener got the event wasn't right yet. Plus it meant that the
secondary listener saw more events than the primary (not all events get
forwarded from the private to the public Process listener.)
This bug became much more evident when we had a stop hook that did some
work, since that delays the Primary listener event delivery. So I also
added a stop-hook to the test, and put a little delay in as well.

On Windows the function name is the full prototype including
the calling convention, all we care about is that the last part
is correct.

(#98041)
In async mode, the test terminates sooner than it should
(`run_to_source_breakpoint` does not work in this mode), and then the
test crashes due to #76057. Most of the time, the test does not fail
because its already XFAILed, but the crash still registers as a failure.

This was just a typo, none of the external execution control functions
should discard other plans. In particular, it means if you stop in a
hand-called function and step an instruction, the function call thread
plan gets unshipped, popping all the function call frames.
I also added a test that asserts the correct behavior. I tested all the
stepping operations even though only StepInstruction was wrong.

(#95181)
…andOverrideCallback (#94518)"
This reverts commit 7cff05ada05e87408966d56b4c1675033187ff5c. The API
test that was added erroneously imports a module that isn't needed and
wouldn't be found which causes a test failures. This reversion removes
that import.

SBCommandInterpreter::CommandOverrideCallback (#94518)"
This reverts commit 6fb6eba9304b63e86ebf039edcb9a0b32e4b39e7.
This test breaks due to an incorrect import in the test.
|
|
SBCommandInterpreter::CommandOverrideCallback (#94518)
`SBCommandInterpreter::CommandOverrideCallback` was not being exposed to
the Python API and has no coverage in the
API test suite, so this commits exposes and adds a test for it. Doing
this involves also adding a typemap for the callback used for this
function so that it matches the functionality of other callback
functions that are exposed to Python.

This is useful if you have a transcript of a user session and want to
rerun those commands with RunCommandInterpreter. The same functionality
is also useful in testing.
I'm adding it primarily for the second reason. In a subsequent patch,
I'm adding the ability to Python based commands to provide their
"auto-repeat" command. Among other things, that will allow potentially
state destroying user commands to prevent auto-repeat. Testing this with
Shell or pexpect tests is not nearly as accurate or convenient as using
RunCommandInterpreter, but to use that I need to allow auto-repeat.
I think for consistency's sake, having interactive sessions always do
auto-repeats is the right choice, though that's a lightly held
opinion...

# Changes
1. Changes to the structured transcript.
1. Add fields `commandName` and `commandArguments`. They will hold the
name and the arguments string of the expanded/executed command (e.g.
`breakpoint set` and `-f main.cpp -l 4`). This is not to be confused
with the `command` field, which holds the user input (e.g. `br s -f
main.cpp -l 4`).
2. Add field `timestampInEpochSeconds`. It will hold the timestamp when
the command is executed.
3. Rename field `seconds` to `durationInSeconds`, to improve
readability, especially since `timestampInEpochSeconds` is added.
2. When transcript is available and the newly added option
`--transcript` is present, add the transcript to the output of
`statistics dump`, as a JSON array under a new field `transcript`.
3. A few test name and comment changes.

The new tests added in #92014 have been flaky on Linaro's
Windows on Arm bot. They appear to be hitting a deadlock trying
to clean up the test process.
This only happens in async mode and I don't see why this test
case needs async mode, so the simple workaround is to stick to
sync mode.
