The climit previously of this commit is heavily used inside a
transactions, so in heavy contention operation such that file thumbnail
creation can cause a db pool exhaust.
This commit fixes this issue setting up a better resource limiting
mechanism that works outside the transactions so, contention will
no longer hold an open connection/transaction.
It also adds general improvement to the traceability to the climit
mechanism: it now properly logs the profile-id that is currently
cause some contention on specific resources.
It also add a general/root climit that is applied to all requests
so if someone start making abussive requests, we can clearly detect
it.
Mainly the followin changes:
- Pass majority of code to the old and plain synchronous style
and start using virtual threads for the RPC (and partially some
HTTP server middlewares).
- Make some improvements on how CLIMIT is handled, simplifying code
- Improve considerably performance reducing the reflection and
unnecesary funcion calls on the whole stack-trace of an RPC call.
- Improve efficiency reducing considerably the total threads number.
- makes the profile access more efficient (replace in-app joins to a
simple select query on profile table
- add partial support for access-tokens (still missing some RPC methods)
- move router definitions to specific modules and simplify the main http
module definitions to simple includes
- simplifiy authentication code related to access-tokens and sessions
- normalize db parameters with proper namespaced props
- more work on convert all modules initialization to use proper specs
with fully-qualified keyword config props
