7a0240694e Fix and test counting Bloom filter. 2013-07-22 14:09:32 +02:00
Matthias Vallentin
532fbfb4d2 Factor implementation and change interface.
When constructing a Bloom filter, one now has to pass a HashPolicy instance to
it. This separates more clearly the concerns of hashing and Bloom filter
management.

This commit also changes the interface to initialize Bloom filters: there exist
now two initialization functions, one for each type:

  (1) bloomfilter_basic_init(fp: double,
                             capacity: count,
                             name: string &default=""): opaque of bloomfilter

  (2) bloomfilter_counting_init(k: count,
                                cells: count,
                                max: count,
                                name: string &default=""): opaque of bloomfilter

The BiFs for adding elements and performing lookups remain the same. This
essentially gives us "BiF polymorphism" at script land, where the
initialization BiF constructs the most derived type while subsequent BiFs
adhere to the same interface.

The reason why we split up the constructor in this case is that we have not yet
derived the math that computes the optimal number of hash functions for
counting Bloom filters---users have to explicitly parameterize them for now.

022ce2505f Change @PATH to @DIR for clarity. Add @FILENAME. Addresses #869.
@DIR expands to directory path of the script, @FILENAME expands to just
the script file name without path.

74e99a27db Ignoring file ids in external tests.
They can change occasionally, and we likewise ignore uids already.

e46300a724 Fixing test that would fail without ES/curl support.
It used to special-case an error message produced in the case that ES
isn't available, however with scripts/test-all-policy.bro now
explicitly disabling ES output, that doesn't seem necessary anymore.

4ccd6d76fd Fixing tests.
Part of this involves making the file-analysis tests independent of
specific hash values. I've done that only partially though.

ae9a02140e Fix the issue with transaction ID reuse in a single DNS connection.
- Each transaction ID within a connection is now maintained as
   a queue of DNS::Info logging records.

 - New function added to the queue.bro script to support
   peeking at the new gettable item in the queue without removing it.

Thanks to git this merge was less troublesome that I was afraid it
would be. Not all tests pass yet though (and file hashes have changed
unfortunately).
