Factor out part of the provisioning script into a
wait-until-service-is-ready script, and put it unconditionally in
front of ExecStartPost=, so that services that depend on influxdb2 are
not started until influxdb2 responds to requests.
Fixes https://github.com/NixOS/nixpkgs/issues/317017 ("Scrutiny tries to start before influxdb has started")
Without the change the doc build fails as:
$ nix build -f nixos config.system.build.manual.manualHTML -L
...
nixos-manual-html> RuntimeError: heading in line 366 does not have an id
This splits a dev output to make the default output not depend on any
build dependencies anymore. This also avoids removing references from
pgxs' Makefile this way, which should, at least theoretically, be good
to build extensions via pgxs, making sure they use the same tooling.
ecpg is the "embedded SQL C preprocessor", which is certainly a dev
tool.
Most important, for closure size anyway, is to move pg_config to the dev
output, since it retains paths to all the other outputs.
The only thing with references to the dev output remaining is then the
postgres binary itself. It contains all the output paths, because it
shows those in the pg_config system view. There is no other way than
to nuke those references to avoid circular dependencies between outputs
- and blowing up closure size again.
This change adds services.pgbouncer.settings option as per [RFC 0042]
and deprecates other options that were previously used to generate
configuration file.
In addition to that, we also place the configuration file under
environment.etc to allow reloading configuration without service
restart.

Done using `grep -rP 'description\s+=\s+"[^"]+[ ]";' | cut -d ':' -f 1 |
xargs -i nvim {}` and sorting the opened files by hand, avoiding
generated packages list
Upgrade default postgresql for stateVersion >=24.11.
This also rebuilds all packages linking against `libpq.so` to use
postgresql 16.
After re-reading https://www.postgresql.org/docs/16/release-16.html
I don't see any major risks about doing that.
Since https://github.com/redis/redis/pull/4001 included in 6.2.0
transparent hugepages works when being set to madvise which is the NixOS
and upstream recommended default.
> WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition.
> Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328.
> To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
these changes were generated with nixq 0.0.2, by running
nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix
two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.
Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.
