This patch-set is an attempt to restructure the project and to make it
build as a native Python package. Although it looks like a complete
rewrite, this is essentially just a switching from using Cython to using
directly the C API of Python. Cython is still being used but only for
the implementation of the NumPy data wrapper. The new building procedure
is very simple and intuitive. The appropriate versions of trace-cmd and
KernelShark libraries are automatically download, patch and build. These
third-party libraries are installed as part of trace-cruncher itself and
do not interfere with any existing system-wide installations of trace-cmd
and KernelShark.
All patches are available at:
https://github.com/vmware/trace-cruncher/tree/refactoring_WIP (branch
"refactoring_WIP")
v2 changes:
- Trying to address the building issues reported by Douglas Raillard in
particular the missing header file and the problem of linking with
libkshark.so.X.Y.Z
- Douglas suggested to use venv in order to avoid the patched versions
of the third-party libraries to pollut the system-wide locations.
Here I am suggesting a different solution that allows to make those
third-party libraries part of the package itself. Not sure which of
the two solution is the best. It will be great if we can have a
discussion.
- All obsoleted source files are removed and the README file is updated
to describe the new building procedure.
