* DEV: Gracefully handle `regex_replace` violations of column length constraints
This is a follow-up to the `remap` [refactor](9b0cfa99c5).
Similar to `remap`, the entire `regex_replace` operation fails if the new content exceeds the column’s max length.
This change introduces an optional mode, controlled by the new `skip_max_length_violations` param
to skip records eligible for `regex_replace` where the new content violates the max column length constraint.
It also includes updates to the exception message raised when `regex_replace` fails to include more details
* DEV: Remove string escapes in heredoc text
* DEV: Gracefully handle remaps which violate DB column constraints
This change implements length constraint enforcement to skip remaps
which exceed column max lengths
* DEV: Only perform skipped column stats lookup when verbose is true
* DEV: Tidy up specs
* DEV: Make skipping violating remap behaviour opt-in
This change introduces a new `skip_max_length_violations` param for
`remap`, set to `false` by default to ensure we still continue to fail
hard when max lenth constraints are violated.
To aid in quick resolution when remaps fail, this change also
adds more context to the exception message to include the offending table
and column information

Constants should always be only assigned once. The logical OR assignment
of a constant is a relic of the past before we used zeitwerk for
autoloading and had bugs where a file could be loaded twice resulting in
constant redefinition warnings.
Rails 6.1.3.1 deprecates a few API and has some internal changes that break our tests suite, so this commit fixes all the deprecations and errors and now Discourse should be fully compatible with Rails 6.1.3.1. We also have a new release of the rails_failover gem that's compatible with Rails 6.1.3.1.
This column often breaks remaps because of some weird, long URLs. The data isn't that important, so truncating a couple of URLs doesn't hurt that much.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
* Cuts number of queries from 273 to 89
* Add some specs
* For a table with 500 posts, benchmarks locally shows a runtime
reduction from 0.046929135 to 0.032694705.
- new hidden site setting 'migrate_to_new_scheme' (defaults to false)
- new rake tasks to toggle migration to new scheme
- FIX: migrate_to_new_scheme also works with CDN
- PERF: improve perf of the DbHelper.remap method
- REFACTOR: UrlHelper is now a class
