bugfix: Fix a race condition when creating guest accounts (#882)
* bugfix: Fix a race condition when creating guest accounts

It was possible to both select the same next numeric ID and then both
attempt to INSERT this into the table. This would cause a UNIQUE violation
which then presented itself as an error in sqlite because it does not
implement `common.IsUniqueConstraintViolationErr`.

The fix here is NOT to implement `common.IsUniqueConstraintViolationErr`
otherwise the 2 users would get the SAME guest account. Instead, all of
these operations should be done inside a transaction. This is what this
PR does.

* Update postgres

* Typo

* Actually use the txn when creating accounts

* bugfix for database is locked on guest reg

Dendrite Build Status Dendrite Dev on Matrix Dendrite on Matrix

Dendrite will be a second-generation Matrix homeserver written in Go.

It's still very much a work in progress, but installation instructions can be found in INSTALL.md. It is not recommended to use Dendrite as a production homeserver at this time.

An overview of the design can be found in DESIGN.md.
