Re: Problem with sharing files

[Christian Grothoff]

Hi!

I looked into this a bit, but could not find it. What is known:

1) The client must be doing a datastore PUT or RESERVE operation (both
are possible), and expects the datastore to return a STATUS response
(type 94), but that never happens.

2) I checked, and on all code paths the datastore should generate a
STATUS for PUT/RESERVE requests. So I figured maybe it is blocked on
some other request, but also that does not seem to be the case from the
code logic. But, hard to be sure.

3) Some paths depend on the storage plugin being used (postgres, sqlite,
mysql, heap). It might help if you could (a) say which one you used, and
(b) tried with a different storage plugin so we can see if this is
plugin-specific.

4) I tried with 'gnunet-publish' on my system, which worked fine. Did
you try the CLI, or only gnunet-fs-gtk? It should not make a difference,
but diagnosing the issue might be easier if we can reproduce it with a CLI.

Last but not least, I did in the past have issues with the database if
it had gotten very big and slow. That's partially because of design
issues in FS, and partially because of naive usage of the database(s) --
depending on which backend you are using.  So another question here is:
how big is your database? I'd usually expect it to be empty if this is
you testing things for the first time, but if your peer was running for
a while, it might have grown to many gigabytes and may be really just
terribly slow...

My 2 cents
