// This test is mainly to verify that we are able to recover from a situation
|
|
// in which the padding file and the padding column are missing during origin
|
|
// initialization. This was originally reported in bug 1425146 comment 39.
|
|
// The situation can be described as follows:
|
|
// 1. A profile is used in FF57. The storage version is 2.1. There's no cache
|
|
// storage for http://www.mozilla.org
|
|
// 2. The same profile is used in FF56. The storage version is still 2.1 which
|
|
// doesn't prevent storage system from working since minor upgrades are
|
|
// backwards-compatible. The cache storage for http://www.mozilla.org is
|
|
// created with schema version 25 (without any padding stuff).
|
|
// 3. The profile is used in FF57 again. Zero padding files for existing cache
|
|
// storages are not created because storage is already at version 2.1.
|
|
// Storage is being initialized and a missing padding file triggers padding
|
|
// size computation from the cache database with schema version 25. Since
|
|
// the computation happens before any real DOM cache operation, the database
|
|
// is not upgraded to schema version 26, so the padding column is missing.
|
|
|
|
add_task(async function testSteps() {
|
|
// The profile contains one cache storage, a script for cache creation and
|
|
// the storage database:
|
|
// - storage/default/http+++www.mozilla.org/cache
|
|
// - create_cache.js
|
|
// - storage.sqlite
|
|
// The file create_cache.js in the package was run locally, specifically it
|
|
// was temporarily added to xpcshell.ini and then executed:
|
|
// mach xpcshell-test --interactive dom/cache/test/xpcshell/create_cache.js
|
|
// Note: it must be executed in FF56 and it only creates the directory
|
|
// "storage/default/chrome/cache" and the file "storage.sqlite". To make it
|
|
// become the profile in the test, additional manual steps are needed.
|
|
// 1. Create "http+++www.mozilla.org" folder under the ""storage/default".
|
|
// 2. Copy the "cache" folder under the "storage/default/chrome" to
|
|
// "storage/default/http+++www.mozilla.org".
|
|
// 3. Remove the folder "storage/default/chrome"
|
|
// 4. Remove the folder "storage/temporary".
|
|
// 5. Add "create_cache.js".
|
|
// 6. Replace the "storage.sqlite" created by FF56 (storage v2.0) with the
|
|
// "storage.sqlite" created by FF57 (storage v2.1)
