Hi Luc,
Could you please let us know by when you are planning to create the
project and associated git for SIAL? Right now we are extracting
libsial from the crash tar ball and using it.
Regards,
Aravinda

Libsial is meant to be a pluggable entity and as such should not require
other pieces to be there ( crash or gdb).
I want to create project and associated git for the library soon. For
now you can extract libsial from the crash tar ball and manage any
modifications using a simple patch mechanism. When the git is available,
we can merge any fixes or enhancements you created for support of
makedumpfile.
Makedumpfile and crash would then feed off of specific branches/versions
of the git repository.
If you have any suggestions or want to help in setting up a public git /
project page for sial, please let me know.
-Luc

Hi Luc,
We are looking for utilising SIAL as a language construct for the
makedumpfile
kernel data filtering from vmcore feature. The details of which are in
the mail
forward.
The proposed enhancement will require libsial.a and as SIAL is not
currently
built/shipped, we are looking for possibilities on how libsial.a can
be made
available to makedumpfile. Please let us know your opinion on the same.
Regards,
Aravinda

Sorry but I cannot give you any help with SIAL. Luc Chouinard is the
maintainer
of the SIAL extension module adaptation for the crash utility, and he
can answer
your questions w/respect to adapting it for makedumpfile.
And ultimately, that's a question for the makedumpfile maintainers.
Dave
