Spent way too long trying to track down a cryptic error that turned
out to be a CherryPy bug. Now we catch this using a decorator in the
'extract' and 'intervals' generators that transforms exceptions that
trigger the bugs into one that does not. fun!
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.
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

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.

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.

variable instead now. Adjust tests accordingly.
Start list --detail option, using stream/intervals request.
Frontend should be ready, backend needs implementation.
Put interval adding back into nilmdb:_add_interval so things work.
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10833 ddd99763-3ecb-0310-9145-efcb8ce7c51f
intervals are accessed, so it doesn't need to keep rebuilding them as
long as it's running.
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10800 ddd99763-3ecb-0310-9145-efcb8ce7c51f
Make nilmdb.cmdline a proper class
Fix various stuff
Add /dbpath command to get DB path
git-svn-id: https://bucket.mit.edu/svn/nilm/nilmdb@10677 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
