// An xpcshell script to create a test database. Useful for creating
|
|
// the test-env-32 and test-env-64 databases that we use to test migration
|
|
// of databases across architecture changes.
|
|
//
|
|
// To create a test database, simply run this script using xpcshell:
|
|
//
|
|
// path/to/xpcshell path/to/make-test-env.js
|
|
//
|
|
// The script will create the test-env-32 or test-env-64 directory
|
|
// (depending on the current architecture) in the current working directory,
|
|
// create a database called "db" within it, and populate the database
|
|
// with sample data.
|
|
//
|
|
// Note: you don't necessarily need to run this script on every architecture
|
|
// for which you'd like to create a database. Once you have a database for one
|
|
// architecture, you can use the mdb_dump and mdb_load utilities (if available
|
|
// for your systems) to create them for others. To do so, first dump the data
|
|
// on the original architecture:
|
|
//
|
|
// mdb_dump -s db path/to/original/test-env-dir > path/to/dump.txt
|
|
//
|
|
// Then load the data on the new architecture:
|
|
//
|
|
// mkdir path/to/new/test-env-dir
|
|
// mdb_load -s db path/to/dump.txt
