Modular or pure Java builds for smaller binaries

[m-sasha]

I need to access an SQLite database for a relatively small feature in my app, and I would really hate to add 10MB to it just for this feature.

Unfortunately, the jars you release contain all the supported native binaries, which makes them quite large. Some of the native binaries I don't need at all, and others I need only for specific builds of my app (e.g. the Windows ones for the Windows build of my app).

It would be much more convenient if you released per-platform jar in addition to the all-in jar. Alternatively, at least for me, it would be enough to have a version that always uses the pure-Java implementation.

I understand that I can repackage the jar myself (that's what I'm planning to do), but still, this would be more convenient.

I'd prefer to have a native-free JAR first. In my case I have the native library locally installed for the loader, thus no need to constantly extract it.

Maybe this is a case of why-not-both :-)

Ideally this project should be split in multiple artifacts, like:

• 1 to describe sqlite operations (without jdbc)
• 1 for jdbc, that uses the one above

Then some implementations of the above:

• JNI (what we currently have) but without the native libs. JNI libs would be packaged in separated jars per OS/arch, so you can get the ones you want, or none if you BYO native lib.
• FFI (Panama). Would require a more recent java, and would not ship the native libs.
• potentially other implementations

I have made a rudimentary port of sqlite-jdbc from JNI to FFM (Java 22+) with no bundled native libraries (there are some other changes as well): https://github.com/Nnnes/sqlite-jdbc-ffm

Perhaps its code could be of some use in this project if someone wants to add FFM support, in particular NativeDB_c.java and sqlite_h.java.

I see quite some unrelated changes. Can they be applied to main?

I do not intend for my changes to be merged in full into this project. I have deleted and modified a large number of parts and it would generally be an unpleasant surprise to most users of this library. I am happy to answer questions or cherry-pick relevant sections as needed.

Fair enough
