| 19:02 | [9ada8a26] part of check-in [ad130bb8] Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test.

| ||
| 20:14 | [0d613164] part of check-in [24b0f66a] Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower.

| 00:34 | [4d360f22] part of check-in [227dc3fe] Add a rudimentary tokenizer and parser to FTS1 for parsing the module arguments during initialization.

| 17:31 | [430513b5] part of check-in [f44b8bae] Add pzErr parameters to the xConnect and xCreate methods of virtual tables in order to provide better error reporting. This is an interface change for virtual tables. Prior virtual table implementations will need to be modified and recompiled. (CVS 3402) (check-in: [f44b8bae] user: drh branch: trunk, size: 20001) | |
| 17:08 | [c68946ed] part of check-in [36693a5c] Add a new zErrMsg field to the sqlite3_vtab structure to support returning error messages from virtual table constructors. This change means that virtual table implementations compiled as loadable extensions for version 3.3.7 will need to be recompile for version 3.3.8 and will not be usable by both versions at one. The virtual table mechanism is still considered experimental so we feel justified in breaking backwards compatibility in this way. Additional interface changes might occurs in the future.
