* Continue rebasing.
* Wrote unit tests for external associations.
* Fix the generated SQL.
Some syntactic sugar (capitalizing the keywords), but use the 'ON' syntax on JOINs.
* whitespace fix post rebase
* We want "management.cattle.io.projects:spec.displayName" not "...spec.clusterName"
* Fix the database calls: drop the key
* Fix breakage during automatic rebase merging gone wrong.
* ws fix - NFC
* Post rebase-merge fixes
* Fix rebase-driven merge.
* Fix rebase breakage.
* go-uber v0.5.2 prefers real arg names to '<argN>'
* Run tests using sqlite DB in a temp directory.
I was running into write-file errors which happens when two sqlite processes try to update the DB at the same time.
* Implement and test the extractBarredValue custom SQL function.
* Explain the DB path constants better.
* Re-order SQL event hooks so events are last
* Add QueryRowContext for single line queries
* Add test case for unknown resource version
* Properly check rows and close it
* More accurate error message when context.Context is canceled
* Re-order test check
This introduces the a `WithTransaction` function, which is then used for all transactional work in Steve.
Because `WithTransaction` takes care of all `Begin`s, `Commit`s and `Rollback`s, it eliminates the problem where forgotten open transactions can block all other operations (with long stalling and `SQLITE_BUSY` errors).
This also:
- merges together the disparate `DBClient` interfaces in one only `db.Client` interface with one unexported non-test implementation. I found this much easier to follow
- refactors the transaction package in order to make it as minimal as possible, and as close to the wrapped `sql.Tx` and `sql.Stmt` functions as possible, in order to reduce cognitive load when working with this part of the codebase
- simplifies tests accordingly
- adds a couple of known files to `.gitignore`
