- New feature: tweaks - New argument `tweaks` to `make_context()` (#49). - New `tweaks()`, essentially constructs a named list of tweaks but with predefined and documented argument names. - `constructor_name`, respected by the `constructor.*` tests. - `strict_identifier`, if `TRUE` all identifier must be syntactic names even if quoted. The quoting test is now split, and a part is ignored conditional to this tweak. The `roundtrip_quotes` tests also respects this tweak. - `omit_blob_tests` for DBMS that don't have a BLOB data type. - `current_needs_parens` -- some SQL dialects (e.g., BigQuery) require parentheses for the functions `current_date`, `current_time` and `current_timestamp`. - `union`, for specifying a nonstandard way of combining queries. All union queries now name each column in each subquery (required for `bigrquery`). - New tests - `dbGetInfo(Result)` (r-dbi/DBI#55). - `dbListFields()` (#26). - New "package_name" test in `test_getting_started()`. - Improved tests - Stress test now installs package in temporary library (before loading `DBI`) using `R CMD INSTALL` before loading DBI (r-dbi/RSQLite#128, #48). - Row count is now tested for equality but not identity, so that backends can return a numeric value > 2^31 at their discretion. - Call `dbRemoveTable()` instead of issuing `DROP` requests, the latter might be unsupported. - Use subqueries in queries that use `WHERE`. - Test that `dbClearResult()` on a closed result set raises a warning. - Expect a warning instead of an error for double disconnect (#50). - Move connection test that requires `dbFetch()` to `test_result()`. - Split "can_connect_and_disconnect" test. - Expect `DBI` to be in `Imports`, not in `Depends`. - Removed tests - Remove test for `dbGetException()` (r-dbi/DBI#51). - Bug fixes - Fix broken tests for quoting. - Self-testing - Test `RPostgres`, `RMySQL`, `RSQLite` and `RKazam` as part of the Travis-CI tests (#52). - Travis CI now installs rstats-db/DBI, updated namespace imports (`dbiCheckCompliance()`, `dbListResults()`). - Use fork of `testthat`. - Utilities - Return test results as named array of logical. Requires r-lib/testthat#360, gracefully degrades with the CRAN version. - Internal - Refactored the `get_info_()` tests to use a vector of names. - Use versioned dependency for DBI - Use unqualified calls to `dbBind()` again - Same as 1.0-8.

Prefer warnings to errors for dbDisconnect() and dbClearResult() #50
