This reports the percentage change between the current head branch and
the main branch, which is exactly the number we'll want to make our
decisions on "success or fail" on.
CI failures will initially be reported for regressions of 5% or more on
an individual number.
Because we separate loadtest results per URL now, we can move the error
tests into the regular mixed bag of loadtests - we will be able to tell
from the misspelled URLs when we hit a regression in that area.
We should be able to do similar things for JWT tests, but we'll need
more infrastructure here.
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.
The most likely offender to fail early is jwt-rsa-cache-worst - which
then cancels *all* loadtests at once. This is unnecessary churn for CI.
Instead we can re-run only that one test later.
- Create separate test suite for observability tests
- Create wrapper script `postgrest-test-observability`
- Add to CI and `postgrest-check`
- Move JWT cache tests under observability tests

The coverage workflow mentions that we run the tests against PG 15,
however that is incorrect and misleading. We actually run it against the
latest supported PostgreSQL version according to the nix scripts.

Renames these scripts to `postgrest-with-pg-xx`. The renaming
helps reduce the length of temporary filenames. This is needed
to ensure that socket file names remain under the maximum
allowed length of 107 chars.
Closes#4461.

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
Previously, the loadtest would always compare against main and the
latest tag. This meant a loadtest running on the v13 release branch,
would compare to a *future* version of both. This is not useful, and
also not supported by `postgrest-loadtest-against`, which recently
introduced a change on `main`, that now breaks the tests on the back
branches.
With this change, the loadtest will always run against the current
target branch of a PR, so against the v13 branch for a PR against v13,
for example. Also, it will compare against the latest released tag *for
that branch*.
Thus, when running this for v12, it will test against the v12 branch and
the v12.2.12 tag.
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
Until now we had a load test with 50k unique JWTs signed with symmetric key.
This commit adds a new load test with 10k JWTs signed with RSA 4096.
Existing -k jwt parameter was changed to -k jwt-hs-50k.
New test is run with -k jwt-rsa-10k parameter.
Additionally a new parameter --jwtcache=off was added to turn off JWT caching in the above load tests.
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.
This just exposes the PostgREST package, not more.
The goal is to avoid duplication, so we're re-using only exports from
default.nix.
