Re: [PATCH] Replaced bz2 decompression code with libbz2

[Ignazio Sgalmuzzo]

Hello Mr. Thibault,
thanks for the reply.
> I guess you have tested this on a bz2-backed filesystem?
I tested with various size .bz2 files (to be clear: "settrans -ca test 
/hurd/storeio -T typed bunzip2:file:test.bz2").
Do I need to do another kind of tests? I'll be happy to check other 
things too, just point me in the right direction.

While testing, I noticed a little problem with "settrans -ca test 
/hurd/storeio -T bunzip2 test.bz2": it seems it looks for a .so module 
with wrong name (something like "libstore_test.bz2.so.0.3)": I want to 
investigate further and eventually fix.

Yes, I'm doing same thing for gzip files support. This just to start, 
possibly other simple things next.
Then, maybe, something more complex: it depends on what kind of progress 
I make and the time I can spend on.

So, if you can show me what I've to sign and what procedure I must 
follow, I'll be very happy to do so.

By the way, looking at the gzip code I saw there's support for zip files 
with various limitations (it takes only first file in archive, it 
recognize encrypted files but does not handle them).
Without zip support (libz doesn't handle it) I can remove nearly all 
compression/file format code using only library functions: effectively 
I've already tested this and it works fine with .gz files. I would like 
to know if it's possible to do in this way. Otherwise I have to modify 
more the existing code to retain the actual zip file functionality.

Sorry for my bad English, I hope it's understandable.
Thanks for your valuable time.

Best regards.
