Add support for relative paths in target library #61

Closed giulianobelinassi closed 3 years ago

giulianobelinassi commented 3 years ago

Now the metadata format accepts relative paths when specifying the path to the target library. The way it works is by comparing both library base name and build id to match the library to patch, instead of relying on the full path to it.

Example:

__ABS_BUILDDIR__/.libs/libparameters_livepatch1.so
@.libs/libparameters.so.0
int_params:new_int_params
float_params:new_float_params

Notice that the line starting with @ do not require to be the full path to target library anymore.
