a49c655816 Strictly enforce (start < end) for all intervals.
Previously, we allowed start == end, but this doesn't make sense with
half-open intervals.

f316026592 Move datetime_tz package under nilmdb.utils
datetime_tz isn't readily available, so it's a lot easier to just
package it within the nilmdb tree.

225003f412 Huge cleanup of namespaces, modules, packages, imports.
Now nilmdb.client, nilmdb.server, nilmdb.cmdline, and nilmdb.utils
are each their own modules, and there is a little bit more of a
logical separation between them.  Various changes scattered throughout
to fix naming (for example, nilmdb.nilmdb.NilmDBError is now
nilmdb.server.errors.NilmDBError).

Reduced usage of "from __future__ import absolute_import" as much
as possible.  It's still needed for the functions in the nilmdb/server
directory to be able to import the nilmdb module rather than the
nilmdb.py script.

This should hopefully ease future packaging a bit.

f355c73209 Refactor utility classes into nilmdb.utils subdir/namespace
There's some bug with the testing harness where placing e.g.
  from du import du
in nilmdb/utils/__init__.py doesn't quite work -- sometimes the
module "du" replaces the function "du".  Not exactly sure why;
we work around that by just renaming files so they don't match
the imported names directly.

9082cc9f44 Merging adjacent intervals is working now!
Adjust test expectations accordingly, since the number of intervals
they print out will now be smaller.

c0f87db3c1 Converted rbtree, interval to Cython. Serious speedups! 2012-11-29 15:13:09 -05:00

f5c60f68dc Speed tests.
test_interval_speed is about O(n * log n), which is good -- but the
constants are high and it hits swap on a 4G machine for the 2**21
test.  Hopefully cython helps!

991039903c Partial implementation of Interval and IntervalSet with a red-black
tree.

This is currently hitting an issue where it's considering the
intersection of [0,1] and [1,2] to be [1,1].  It matches the 
fully-closed definition of intervals, unlike before -- but might
cause issues.  Need to consider whether test case is correct.

ea3e92be3f Some prep work for merging adjacent insertions.
Doesn't actually merge them yet; need to change Interval
implementation to allow deletes.

4501da6edc Can query intervals now.
On the big database, the server takes a few seconds to figure out the
interval intersections.  Need to think about how to improve that --
the real key might be to start reducing the number of intervals we're
storing by combining them, potentially as they're inserted.

b84ffddd50 New bxinterval implementation is at least linear -- not much better in
the TestIntervalSpeed versus the previous bisect version, but should
be better in general.

cc4e3bdb76 Rename some nilmdb methods to be private
More work with nilmdb.stream_insert.  Checks for overlap between
parser output and database intervals, and actually inserts the
data into pytables.  Need to benchmark/figure out whether we can
use table.append rather than the row.append() nonsense -- it could
simplify things quite a bit.

Improve layout class and add tests to get more coverage.  Better
error handling on invalid inputs (reports the reason for the error)

Replace layout.fillrow with layout.filltable, but turns out that we
can probably just remove it anyway.

Add nilmdb.Timer for simple timing tests

Move some duplicated test suite helper functions into a new file,
test_helper.py

Add class to test_interval.py to match the others

cf66eca42c Spent time trying to get Intervals and IntervalSets to handle a gap
tolerance in equality comparisions, but it's a real pain to get all
the edge cases right, and it's not clear we actually need that
functionality at the moment.  Skip it for now.
