* Avoid infinite recursion when bad values are passed to tz aware fieldsSean Griffin2016-02-021-0/+7
| | | | | | | | | | | | | | | We had previously updated this to attempt to map over whatever was passed in, so that additional types like range and array could benefit from this behavior without the time zone converter having to deal with every known type. However, the default behavior of a type is to just yield the given value to `map`, which means that if we don't actually know how to handle a value, we'll just recurse infinitely. Since both uses of `map` in this case occur in cases where we know receiving the same object will recurse, we can just break on reference equality. Fixes #23241.

| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f6db31ec16e42ee7713029f7120f0b011d1ddc6c. Reason: Scope names can very easily conflict, particularly when sharing Concerns within the team, or using multiple gems that extend AR models. It is true that Ruby has the ability to detect this with the -w option, but the reality is that we are depending on too many gems that do not care about Ruby warnings, therefore it might not be a realistic solution to turn this switch on in our real-world apps.

| * | Fix corrupt transaction state caused by `before_commit` exceptionsJeremy Daer2016-02-011-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a `before_commit` callback raises, the database is rolled back but AR's record of the current transaction is not, leaving the connection in a perpetually broken state that affects all future users of the connection: subsequent requests, jobs, etc. They'll think a transaction is active when none is, so they won't BEGIN on their own. This manifests as missing `after_commit` callbacks and broken ROLLBACKs. This happens because `before_commit` callbacks fire before the current transaction is popped from the stack, but the exception-handling path they hit assumes that the current transaction was already popped. So the database ROLLBACK is issued, but the transaction stack is left intact. Common cause: deadlocked `#touch`, which is now implemented with `before_commit` callbacks. What's next: * We shouldn't allow active transaction state when checking in or out from the connection pool. Verify that conns are clean. * Closer review of txn manager sad paths. Are we missing other spots where we'd end up with incorrect txn state? What's the worst that can happen if txn state drifts? How can we guarantee it doesn't and contain the fallout if it does? Thanks for @tomafro for expert diagnosis!

There are additional issues with this commit that need to be addressed before this change is ready (see #23377). This is a temporary revert in order for us to have more time to address the issues with that PR, without blocking the release of beta2.

| | | | | | | | | | | | | | | | | | | | | | | | If `AR.primary_key` is called for a table who has composite primary key, the method returns `nil`. This behavior sometimes generates invalid SQL. The first time developers notice to invalid SQL is when they execute SQL. This commit enables developers to know they are doing something dangerous as soon as possible.

* | Do not use default attributes for STI when instantiating a subclassSean Griffin2016-01-271-0/+4
|/ | | | | | | | | | The commit which originally added this behavior did not consider that doing `Subclass.new` does not actually populate the `type` field in the attributes (though perhaps it should). We simply need to not use the defaults for STI related things unless we are instantiating the base class. Fixes #23285.

| | | | | | | | | | | | | | | | | | | | | | | | | | When updating an associated record via nested attribute hashes the reject_if proc could be bypassed if the _destroy flag was set in the attribute hash and allow_destroy was set to false. The fix is to only short-circuit if the _destroy flag is set and the option allow_destroy is set to true. It also fixes an issue where a new record wasn't created if _destroy was set and the option allow_destroy was set to false. CVE-2015-7577

| * | [close #23009] Limit key lengthschneems2016-01-211-7/+29
| | | | | | | | | | | | | | | | | | | | | Mysql has a weird bug where it cannot index a string column of utf8mb4 if it is over a certain character limit. To get compatibility with msql we can add a limit to the key column. 191 characters is a very long key, it seems reasonable to limit across all adapters since using a longer key wouldn't be supported in mysql. Thanks to @kamipo for the original PR and the test refactoring. Conversation: https://github.com/rails/rails/pull/23009#issuecomment-171416629

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - We don't need the select scope added by user as we only want to max timestamp and size of the collection. So we already know which columns to select. - Additionally having user defined columns in select scope blows the cache_key method with PostGreSQL because it needs all `selected` columns in the group_by clause or aggregate function. - Fixes #23038.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes incorrect assumptions made by e991c7b that we can assume the DB is already casting the value for us. The enum type needs additional information to perform casting, and needs a subtype. I've opted not to call `super` in `cast`, as we have a known set of types which we accept there, and the subtype likely doesn't accept them (symbol -> integer doesn't make sense) Close #23190
