Previously, we could get empty intervals anyway by having a non-empty
interval and removing a smaller interval around each piece of data.
Turns out that empty intervals are OK and needed in some situations,
so explicitly allow and test for it.
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.
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.
Doesn't actually merge them yet; need to change Interval
implementation to allow deletes.

row individually, when extracting data.
Switch to using bisect module when doing the bisection, to lessen the
chance of errors.
Added syslog ability for timer module, for timing stuff deep inside
the server.
Make the chunked/non-chunked test just give a warning, rather than
failing the tests, for debugging purposes. Alternate approach would
be to disable "die on error" for the tests.

though; need to figure out where the slowdown lies.
Add stream existence check to server's /intervals and /extract paths,
add tests for it.
Make start and end arguments optional for /extract, like /intervals
Move --quiet command line option to just the insert subcommand.
It's the only one that uses it right now, and otherwise it doesn't
show up in after a "nilmtool.py intervals --help". Might revisit this
later if more commands start supporting --quiet.
Change cmdline/extract's write into a print, to keep the trailing
newline.
Fix lingering uses of Interval in nilmdb and change to DBInterval
instead.
Fix nilmdb interval bisection:
- handle common case optimization correctly
- db_endpos is always one after the last row, so use hi=db_endpos-1
Finish nlimdb stream_extract
Add a bunch of cmdline tests for extract, particularly testing border
cases around start/end. Compares output to a set of files stored in
the tests/data dir.
Some more tests in test_client to get better coverage.

- Flesh out tests for the new nilmdb.layout.Formatter
Coverage doesn't handle the cython module, so this is just
functional stuff, not necessarily complete.
Still need to finish each Layout.format()
- Split out test_client_5_chunked from test_client_4_misc
so it's easier to skip while debugging. Turning off streaming
lets us see tracebacks from within the server's content()
functions.
- More work on stream/extract in cmdline, client, server, nilmdb.
Still needs work on server side, but should be complete in nilmdb.
- Start nilmdb.layout.Formatter class

that. This requires a bit of restructuring of server.py:intervals()
to allow us to properly report errors before beginning the stream.
Make the nilmdb.httpclient save a copy of HTTP header responses, and
add a test that the saved responses to verify that the
transfer-encoding is Chunked for the /stream/interval request. This
should check that the above bug is fixed and doesn't show up again
if we switch to a different WSGI server, etc.
Tweak size estimates in nilmdb for /stream/interval

cover overlapping data, missing data, etc.
Consolidate nilmdb.client.MyCurl.getjson() and putjson().
Add __str__ for more compact representation of IntervalSet
Make stream_id not NULL in SQL database.
Format NilmDBError with name of exception for more clarity
Work around CherryPy issue 1138 by removing HTML escaping before
returning JSON error responses from the server.
Reached 100% test coverage again (woohoo)
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10665 ddd99763-3ecb-0310-9145-efcb8ce7c51f
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
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10661 ddd99763-3ecb-0310-9145-efcb8ce7c51f
Change expected_daily_rows into rate_hz just for simplicity
nilmdb.layout.Parser now validates that timestamps are monotonically
increasing, and remembers the min and max seen.
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10660 ddd99763-3ecb-0310-9145-efcb8ce7c51f
Add "end" parameter to TimestamperRate, to force the file to end
before a specific time. Will be good for loading in old files and
knowing that things don't overlap.
