Re: [AVFS] resurrection of AVFS

Source code is nearly uncommented :(
No tutorial, no API documentation, this situation could not attract more developers to use this library in their projects. I could write a basic tutorial with examples of use with some help from you.
Investigating runtest.c is a good start point, are there more examples anywhere else?

Well, as an API I could count functions from "virtual.h". Correct me if I'm wrong.
There is no documentation but functions from virtual.h seem s to behave like their libc counterpards. Function virt_read() behaves like read() but with support for reading from archives, it takes the same arguments, it return the same error codes and so on.

Can I use AVFS for reading ordinary (real) files from local?
I hope I can.

How to set temporary directory for archive cache?

When is cache cleaned? Am I supposed to do it explicitly?
    fd = virt_open("/#avfsstat/cache/clear", O_WRONLY, 0);
    res = virt_write(fd, "1", 1);
    res = virt_close(fd);
..striped function flush_cache() in runtest.c


How you test archive change the situation someone copy file into the ZIP file.
In which sourcefile, which function I can foud it?
Is there something like 'dirty flag'?

Is some kind of server started to keep tracks of opened archives?
(suppose using avfs as library, no avfscoda, preload or fuse)

From sourcecode organisation it looks like AVFS comes in four flavour.
- library (layer libary above some functions from glibc)
- avfscoda
- preload (overload some methods in libc/glibc, so applications use avfs transparetly without)
- fuse module

In documentation only flavours 2 and 3 are mentioned!

From further investigation of mail-lists - only flavour 1 is fully operational now, flavours 2 - 4 seems not to be fully operational (or not operational at all) in newer glibc and kernels (>2.6.x).
