Let's use the same dependency when creating key material and when
creating tokens, no need to carry multiple different dependencies and
converting keys between them.
Instead of passing a path to the output target file, just pass the
directory in which to create the file. This allows the script to create
multiple files later.
When we changed the test structure to use libfaketime, we moved away
from generating targets as part of the chained command running
with-pg/with-pgrst. This function was left-over from that, the
genTargets script does not need to relay its remaining arguments
arguments anymore.
Instead of creating separate test suites for the key type, the PostgREST
instance now accepts both keys via a JWKSet and the targets are
generated 50/50 for both.
The results are still reported seperately by using a different URL,
which shows up as separate rows in the results.
Instead of taking wild guesses at the runtime of the target generation
itself, we're just making sure to reset the system time to a fixed value
when we ultimately start PostgREST. This allows us to create the right
JWT expiry values ahead of time.
Chaining the target generation command after the build is done ensures
that if a build takes too long, the dynamic target generation for vegeta
won't cause 401 Unauthorized errors due to already expired JWTs.
Also split the rsa materials writing to another python program for
easier maintenance.
Currently the `postgrest-loadtest -k jwt-*` loadtests use the OPTIONS method,
which is good for isolating the perf changes for JWT auth.
But using GET is more accurate for actual perf improvements,
since it actually hits the database.
This adds a method argument for postgrest-loadtest, so GET can be used like:
```
postgrest-loadtest -k jwt-hs --method GET
```
CI is not changed, this is mostly useful for manually checking variance.
Completes the jwt loadtests, now we have non-cached, cached + worst case
for the cache.
- jwt-hs (edited): now has the cache disabled
- jwt-hs-cache: cache enabled for jwt-hs
- jwt-hs-cache-worst: worst case of the jwt-hs cache
- jwt-rsa (edited): now has the cache disabled
- jwt-rsa-cache: cache enabled for jwt-rsa
- jwt-rsa-cache-worst: worst case of the jwt-rsa cache
Also deletes `nix/tools/generate_targets_rsa.py` and uses a single
python script.
Should prove what's mentioned on
https://github.com/PostgREST/postgrest/pull/4084#issuecomment-2998170423
This is so the process monitoring results are more meaningful.
* remove the amount of total targets from the loadtest kind name
since the targets can change.
* clarifies the top comment on the generate_targets python script
* increase TOTAL_TARGETS on jwt-hs loadtest
This loadtests the jwt decoding logic. For this it adds an optional
`-k`(kind) parameter to `postgrest-loadtest` and
`postgrest-loadtest-against`.
Old kind (default):
```
postgrest-loadtest -k mixed
postgrest-loadtest-against -k mixed
```
New kind:
```
postgrest-loadtest -k jwt
postgrest-loadtest-against -k jwt
```
Internally it uses a dynamically generated targets file using python
which looks like:
```
GET http://postgrest/authors_only
Authorization: Bearer <jwt>
GET http://postgrest/authors_only
Authorization: Bearer <another-jwt>
...
```
Then this is used to run vegeta with the `-lazy` option.
