Specifying path to source files

[aulwes]

Hi,

How do I specify the path(s) to the source files so that they are displayed in malt-webview?

Thanks,Rob

Hi Rob,

two answers :

1. You first need to build your program or libraries with -g option to get the debug symbols in the binary so malt can find the source file paths.
2. If for some reasons, you built your program on another computer and install for example an RPM you might not have the sources in the same exact path when you run the MALT webview. In this case you can override some paths to redirect them to another directory by using the -o/--override option.

Eg, if you built with sources in /rpm/.... and run on another machine where you copied the sources in /home/me/

malt-webview --override /rpm/my-project:/home/me/my-project -i malt-123456-my-program.json

Fill free to precise if it is not working for you.

[aulwes]

I tried the -o option, but isn't working. Is there a way to display the original source path that web view is expecting?

[svalat]

Ohhhh, thanks for the report, there is effectively a real bug.

You can see the path of the file in the webview source browser when it failed to fetch the file.

You are most probably in the case where your sources are pointed via a relative paths which trigger a bug in the webview making the './' disappearing while arriving on the mini-server.

I fixed it in master branch.

If you are in this case it might be fixed.

For relative path replacement you might use, or it might work automatically if you are located in the source directory.

malt-webview --override ./:/home/me/my-project -i malt-123456-my-program.json

If you can confirm it is your issue.

[aulwes]

I'm still unable to get it to work, even after pulling your fix. Let's say my source code is located on the remote machine at /usr/workspace/myproject/src I copied the json output malt file to my local machine and cloned 'myproject' in the same directory. I then tried malt-webview --no-auth -p 9090 -i output.json -o /usr/workspace/myproject/src:./myproject/src I still don't see the source code. I did make sure to build my executable with '-g'.

Pretty sur I still have an issue on the ./ in the target part of the redirection, I will give a look.

Waiting the patch, can you try to put a full path instead of ./ ?

[svalat]

In principle I made the fix on master branch.
If you can check and confirm or infirm.

[aulwes]

I rebuilt, but now I'm getting this error when I attempt to run: srun -n 4 --ntasks-per-socket=2 --cpus-per-task=2 $MALT_ROOT/bin/malt -s libunwind --mpi -- myapp.x /g/g15/aulwes1/workspace/malt/src/lib/stacks/Stack.cpp:497: void MALT::Stack::fastSkip(int): Assertion `depth >= 0 && depth < size' failed. /usr/workspace/perfeng/utils/malt/bin/malt: line 448: 524516 Aborted (core dumped) LD_PRELOAD="${MPI_WRAPPER_DIR}/libmaltmpi.so:${MALT_LIB}:${LD_PRELOAD}" "$@" /g/g15/aulwes1/workspace/malt/src/lib/stacks/Stack.cpp:497: void MALT::Stack::fastSkip(int): Assertion `depth >= 0 && depth < size' failed. /g/g15/aulwes1/workspace/malt/src/lib/stacks/Stack.cpp:497: void MALT::Stack::fastSkip(int): Assertion `depth >= 0 && depth < size' failed. /usr/workspace/perfeng/utils/malt/bin/malt: line 448: 524512 Aborted (core dumped) LD_PRELOAD="${MPI_WRAPPER_DIR}/libmaltmpi.so:${MALT_LIB}:${LD_PRELOAD}" "$@" /g/g15/aulwes1/workspace/malt/src/lib/stacks/Stack.cpp:497: void MALT::Stack::fastSkip(int): Assertion `depth >= 0 && depth < size' failed. /usr/workspace/perfeng/utils/malt/bin/malt: line 448: 524511 Aborted (core dumped) LD_PRELOAD="${MPI_WRAPPER_DIR}/libmaltmpi.so:${MALT_LIB}:${LD_PRELOAD}" "$@" /usr/workspace/perfeng/utils/malt/bin/malt: line 448: 524514 Aborted (core dumped) LD_PRELOAD="${MPI_WRAPPER_DIR}/libmaltmpi.so:${MALT_LIB}:${LD_PRELOAD}" "$@" flux-job: task(s) exited with exit code 134 I built using: cmake .. -DLIBUNWIND_PREFIX=/usr/lib64/libunwind-x86_64.so -DCMAKE_INSTALL_PREFIX=/usr/workspace/perfeng/utils/malt The compilers I'm using are Clang 14.0.6.

So if I well understand you get the issue since you moved to master branch and before you got success with probably the released version 1.2.1 ?

Or am I wrong ?

[aulwes]

I'm sure I've made a mistake somewhere. I was getting this same error before as well, but at that time, the fix was to use GCC 9.3.0 and also to specify '-s libunwind'. However, this time, I tried the same thing, to use GCC 10.3.0 and libunwind, but getting this error again. I then tried '-s enter-exit' and this option worked. But does this mean I won't get a stack trace?

The issue related to fastSkip is related the the backtrace on which I skip the first entries not to look on my own internal functions. But the exact value to use might depend on the way your compiler as inlined some functions. In principle this is detected but I probably have an issue if you get the error.

You can try to see if another value of the skip parameter might fix your issue manually via the options :

malt -o stack:skip=3 ......
malt -o stack:skip=4 ......
malt -o stack:skip=5 ......

[aulwes]

Yup, stack:skip=3, worked!! Thanks!!

As you directly call cmakeyou can also try to build in release mode which enable all the optimizations which impact this. I apply it automatically if you use the ./configure script.

Probably i need to fix something in debug mode.

cmake .. -DCMAKE_BUILD_TYPE=Release .......

[aulwes]

Ok, I'll try that, thank you!

I moved the second issue your reported in #76 so I can close this one.

[aulwes]

Ok, thanks, I’m still having trouble getting the source code to appear. I’m trying to add log outputs in the webview source to show where it thinks the source codes are located.
