Martin Desruisseaux commented on SIS-366:
-----------------------------------------
Partial fix committed as of revision 1811420: for the
{{apache-sis-bin-0.8.jar}} file, the native files are stored in {{lib/linux}},
{{lib/darwin}} or {{lib/windows}} directories. However this fix does not yet
apply to usage in other context (for example, it does not yet apply to JAR
files used in Maven project).
> sis-gdal module should not write native file in the temporary directory

> Key: SIS-366
> URL: https://issues.apache.org/jira/browse/SIS-366
> Project: Spatial Information Systems
> Issue Type: Bug
> Components: Storage
> Affects Versions: 0.8
> Environment: Linux, MacOS
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Fix For: 0.8
>
>
> The {{sis-gdal}} module uses Java Native Interface (JNI) for accessing the
> Proj.4 library. Currently, the JNI are pre-compiled in
> {{storage/sis-gdal/src/main/resources/native/<OS>/libproj-binding.so}} files
> where {{<OS>}} is {{linux}} or {{darwin}}. The file size is about 14 kb.
> Since we can not load a library from a JAR file, we have to copy it as a
> regular file somewhere. Current implementation copies it in the temporary
> directory.
> Problem is that some environments do not give execution permission in the
> temporary directory. Consequently we should save the {{libproj-binding.so}}
> files somewhere else. Some possibilities are:
> 1. Platform-specific directory like {{<user directory>/Library}} on MacOS.
> 2. A sub-directory of {{$SIS_DATA}}.
