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!
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.

Doesn't actually merge them yet; need to change Interval
implementation to allow deletes.

Current/old design has specific layouts: RawData, PrepData,
RawNotchedData.
Let's get rid of this entirely and switch to simpler data types that
are
just collections and counts of a single type. We'll still use strings
to describe them, with format:
type_count
where type is "uint16", "float32", or "float64", and count is an
integer.
nilmdb.layout.named() will parse these strings into the appropriate
handlers. For compatibility:
"RawData" == "uint16_6"
"RawNotchedData" == "uint16_9"
"PrepData" == "float32_8"

This lets us quickly count the number of matching rows, rather than
returning them.

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

into a generator. Needed to get pycurl's WRITEFUNCTION to give us a
generator instead. It's a bit tricky and uses threads and queues, but
seems to work OK.

us to look at just some of the intervals without having to reconstruct
an entire IntervalSet class -- which greatly reduces server load when
handling requests that cover large interval ranges.
Add Client.get and Client.put, analogous to getjson and putjson but
without parsing the result as json.
Add Client.stream_extract. Still needs server side love.
Allow Cmdline subcommands to provide a return value that turns into
the exit code.
More work on cmdline.extract.
