Colin Dellow 92ba5f94e0 reuse FileMetaData
For the statscan dataset, parsing the file metadata takes ~30-40ms,
so stash it away for future re-use.

Colin Dellow 1f938a005d More tests cases to deal with affinity
I'm not sure how these manifest - whether SQLite retypes them based on
column affinity before we see them, or whether they're provided as is.

Colin Dellow 095b576cc2 Scaffolding for row group filters, tests
rowid is special since its column index is -1, so add
explicit tests around it

Colin Dellow 5559a7b563 Fix when last rowgroup is not same size as first
...change test data to use 99 rows, so that when we have
rowgroup size 10 we exercise this code.

Colin Dellow b7c134efc0 test-queries: can debug a testcase
`tests/test-queries regex` filters the test cases.

If the resulting set has only one test case, run it under gdb.

Colin Dellow 35fcde926c Rewrite SQL oracle harness 2018-03-07 20:20:34 -05:00
Colin Dellow caefc23b1e Add a pg oracle
- define `datetime`, `printf` fns in pg so it produces similar
  output as sqlite

- tidy up input data to be less wide

To do: some fns to make it easy to generate a new test case. Probably
want to mount all the 3 parquets simultaneously and refer to the
sqlite table by the same name as the pg table.

Colin Dellow 0d4806ca6f Rejig parquet generation
- "fixed_size_binary" -> "binary_10"
- make null parquet use rowgroups of sie 10: first rowgroup
  has no nulls, 2nd has all null, 3rd-10th have alternating
  nulls

This is prep for making a Postgres layer to use as an oracle
for generating test cases so that we have good coverage before
implementing advanced `xBestIndex` and `xFilter` modes.

Colin Dellow 552da5a647 Initial checkin of CSV table
parquet.cc is a fork of the sample CSV virtual table at
https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/csv.c

So far the only changes are those needed to make it compile cleanly in
C++11 mode.
