Previously the count returned by insert and copy was wrong because
the count was reset on every execute. But, often there is an execute
in the middle of an insert (i.e. to create a chunk). This fixes the
logic to reset the count only at the start of the top-level statement.
Fixes#64
Clean up the table schema to get rid of legacy tables and functionality
that makes it more difficult to provide an upgrade path.
Notable changes:
* Get rid of legacy tables and code
* Simplify directory structure for SQL code
* Simplify table hierarchy: remove root table and make chunk tables
* inherit directly from main table
* Change chunk table suffix from _data to _chunk
* Simplify schema usage: _timescaledb_internal for internal functions.
* _timescaledb_catalog for metadata tables.
* Remove postgres_fdw dependency
* Improve code comments in sql code
remove all murmur3-related source code. Alter regression tests
to reflect new hash values for inputs, and a slightly different
set of input data to ensure that sufficient chunks and partitions
are tested. Some changes to .sh scripts in sql/setup that seem
to be used only to power the "unit tests", which I cannot
yet run successfully.
Previously, each test set their own (although mostly the same)
configuration for log output and error verbosity. This is now set
globally in the test runner so that tests only need to set these
configuration parameters if they need to override the defaults. The
log verbosity is also reduced so that errors aren't generated with the
line number of the source file that output the error. Line numbers in
the output can break tests when upgrading to a new PostgreSQL version
that outputs a different line number.
If an error is generated in any of the insert triggers, the insert
state kept during a batch insert might be left in an undefined state,
breaking the next insert. This patch makes sure errors are captured in
the insert triggers so that the state can be cleaned up.
- Directory structure now matches common practices
- Regression tests now run with pg_regress via the PGXS infrastructure.
- Unit tests do not integrate well with pg_regress and have to be run
separately.
- Docker functionality is separate from main Makefile. Run with
`make -f docker.mk` to build and `make -f docker.mk run` to run
the database in a container.
