Changes in comparison to v1:
- Try to fix https://autobuilder.yoctoproject.org/valkyrie/#/builders/23/builds/3070
The tests does remote debugging in Qemu. It sets a breakpoint on a line
which is optimized out by the compiler. That's now fixed by setting the
breakpoint on the next line, which is always there.
So far this is understood and fixed. But what is not yet fully understood
is: Why does it pass on x86 hosts but not on arm hosts?
- Improve remote debugging
- Added GDB pretty-printing for C++ STL types (e.g., std::vector) to
improve visibility during debugging.
- Evaluated DEBUG_PREFIX_MAP for accurate source mapping in debug
sessions.
- Introduced gdbserver attach mode for more flexible remote debugging.
- Moved the code that starts GDB sessions on the remote target from
wrapper scripts into VSCode JSON files. This simplifies
customization and improves transparency.
- Improve test coverage for ide-sdk features
- Test the complete VSCode remote debugging workflow by reading VSCode
JSON files.
- Added example code using std::vector and tests for pretty-printing.
- Extended the CMake and Meson examples with a service and added test
coverage for the new GDB attach mode.
- Added debug logging in DevtoolIdeSdkTests to aid troubleshooting.
- Fixes
- Located and integrated bitbake-setup init-build-env for consistent
environments.
- Misc
- Added a compile step in ide-sdk tests to ensure builds are up to
date. This is required when bitbake supports running do_install
without dependent tasks.

With poky the oe-init-build-env script from the top level directory of
the layer with the higher priority is used to setup the build
environment.
This does no longer work with bitbake-setup. The directory layout
changed and the script is now called init-build-env. Skip the old
implementation if $TOPDIR/init-build-env exists and use it instead.

Add optional debug logging to all runCmd calls in DevtoolIdeSdkTests
to improve debugging capabilities when tests fail. The logging is only
enabled when the test logger is set to DEBUG level.

Extend the C++ example to run as systemd/SysV services
This change adds service capability to the existing C++ example without
modifying its original behavior. The example can now run either as:
- One-shot executables (existing behavior)
- Long-running services via systemd or SysV init
The service runs as an unprivileged user/group, demonstrating security
best practices for service development. This introduces additional
complexity to the build process, particularly around proper pseudo usage
in development builds. The implementation includes:
- Service configuration files (systemd .service and SysV init script)
- Dedicated user/group creation with appropriate permissions
- JSON configuration file for runtime customization, owned by the
service user
- Command-line --endless flag to enable service mode
- Full support for both CMake and Meson build systems
This enhancement enables testing debugger configurations that attach to
running processes, expanding the examples' utility for development tools.

To: openembedded-core; +Cc: Adrian Freihofer
From: Adrian Freihofer <adrian.freihofer@siemens.com>
When running the devtool ide-sdk test with qemu, verify that the example
services are actually running on the target by using pgrep to check for
the example executable names.
Also verify that the configuration files in /etc are owned by the proper
user and group, both before and after the install_and_deploy scripts
have run. This is also a check that the install_and_deploy scripts
are working correctly with pseudo.

To: openembedded-core; +Cc: Adrian Freihofer
From: Adrian Freihofer <adrian.freihofer@siemens.com>
Enhance remote debugging configuration to support multiple modes
per executable binary. This adds support for gdbserver's attach
mode as an additional debug configuration.
When the binary is detected to run as a systemd service or SysV
init script, an attach debug configuration is generated alongside
the regular configuration that starts the process via gdbserver.

To: openembedded-core; +Cc: Adrian Freihofer
From: Adrian Freihofer <adrian.freihofer@siemens.com>
Move code which is used by the ide_none plugin from the base class
to the ide_none plugin. This is just a refactoring, no functional
change.

Previously, the target was hardcoded in the install_and_deploy script,
limiting flexibility. This change allows passing the target as a
command-line argument, enabling IDEs to configure the target dynamically
rather than only at IDE configuration generation time.
This is a first step towards making the target configurable from the IDE.

Write the ssh command to start gdbserver on target directly into the
tasks.json. This avoids the need to create one more script file on the
host. It also simplifies manual modifications of VSCode's standard
tasks.json which is much more handy than modifying multiple proprietary
scripts used to launch gdbserver.

This adds more test coverage for devtool ide-sdk, with VSCode. The cmake
test case has now a full remote debugging test on Qemu. The test checks
the generated launch.json and tasks.json files, starts gdbserver and
connects to it. The test verifies breakpoints, variables and source file
listing.

From: Adrian Freihofer <adrian.freihofer@siemens.com>
Improve the reverse mapping for searching the source files for remote
debugging by taking the details from DEBUG_PREFIX_MAP into account when
generating GDB's debug-file-directory mappings. This allows settings
such as DEBUG_PREFIX_MAP = "" for modified recipes to be used to avoid
any path remapping.
Background:
For packaged debug-symbols, the references to the source code need to be
relocated to paths which are valid on the target system. By default,
devtool ide-sdk tries to keep the relocated paths and configures the
debugger to reverse map them back to the original source paths. The goal
is to provide a debug setup which is a close as possible to a regular
build.
Usually this works well, but there are situations where the reverse
mapping is not unambiguous. For example the default DEBUG_PREFIX_MAP
DEBUG_PREFIX_MAP ?= "\
-ffile-prefix-map=${S}=${TARGET_DBGSRC_DIR} \
-ffile-prefix-map=${B}=${TARGET_DBGSRC_DIR} \
adds two different source paths (${S} and ${B}) to the same target path
(${TARGET_DBGSRC_DIR}). If both source paths contain files with the same
name, the debugger cannot determine which source file to use. For this
example it is usually sufficient to only map ${S} to the target path.
The source files in ${B} are probably a few generated files which are
not that interesting for debugging. But depending on the project, the
files in ${B} might also be relevant for debugging.
Also add a hint to the generated local.conf snippet to use
DEBUG_PREFIX_MAP = "" if the user wants to optimize the build for
debugging.

Add a standard container (std::vector) to the C++ example program to
demonstrate the debugger's capability to inspect and traverse STL
containers during a debugging session. This requires enabling GDB's
pretty-printing feature, which depends on Python scripts shipped with
the compiler.

GDB requires Python scripts provided by GCC to properly display C++ STL
types. This commit adds support for configuring GDB to use these
pretty-printers in the ide-sdk, covering both the ide_none and ide_code
plugins.
The implementation locates the GCC Python helper scripts in the sysroot
and injects the necessary commands into the GDB initialization files and
IDE debug configurations. This ensures that when debugging C++
applications, STL containers and other complex types are displayed in a
readable format.
Without this:
(gdb) print numbers
$1 = {<std::_Vector_base<int, std::allocator<int> >> = {
_M_impl = {<std::allocator<int>> = {<std::__new_allocator<int>> =
{<No data fields>}, <No data fields>}, <std::_Vector_base<int,
std::allocator<int> >::_Vector_impl_data> =
{_M_start = 0x55555556c370, _M_finish = 0x55555556c37c,
_M_end_of_storage = 0x55555556c37c}, <No data fields>}},
<No data fields>}
With this:
(gdb) print numbers
$1 = std::vector of length 3, capacity 3 = {1, 2, 3}

Add explicit compile step to the ide-sdk test workflow. The current
implementation relies on calling bitbake -c install to perform the
install step, which also triggers a build. But this will change when
bitbake will support task execution without handling dependencies.
To make the tests future-proof, add an explicit compile step after
modifying the source code.
This also improves the test coverage for meson based recipes, as the
compile step is now explicitly tested.

I know debugging this might be a bit tough, as it is arm host only. If
you have doubts about what is failing, I can do some tests next week.
Thanks,

Hi Antonin
My proposal for proceeding here is to drop one patch from my series:
[OE-core] [PATCH v2 13/14]
oe-selftest: devtool: add test for gdb pretty-printing
This one get killed by patches which are currently on master-next too.
This makes it almost impossible to fix at the moment.
When things will settle down, I will test and send this one again.
It is just one more test step which would be nice to have but not
essential.
It also fails only on a ARM host, which I cannot reproduce.
All in all just too many floating parts for getting this to final state
right now.
Could we please proceed with 13 out of 14 patches from my series as a
next step? Mathieu already hat such a branch for a while.
Thank you.
Adrian

Sorry for messing up with what Mathieu had on his branch, probably a miss on my
side as I've picked up his work.
I picked your patches again, and while some oe-selftest runs did succeed, I hit
this error, which seem related to your series:
https://autobuilder.yoctoproject.org/valkyrie/api/v2/logs/4983396/raw_inline
From this build:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/35/builds/3035
It was run with the following commits:
https://git.yoctoproject.org/poky-ci-archive/log/?h=oecore/autobuilder.yoctoproject.org/valkyrie/a-full-3073
I don't recall hitting the issue before having your series in my branch, so to
be sure I ran another build with only your series applied on master, and I still
have the issue:
https://autobuilder.yoctoproject.org/valkyrie/api/v2/logs/5038061/raw_inline
Can you have a look?

Yes, it seams that my patches can trigger this race issue. I sent a v3
with a fix.
Thank you for the extra effort. It's very helpful.
