Sergei Shulepov 72a92eaf9e configuration: Rename validation_upgrade_{frequency -> cooldown} (#4635)
This just renames a member of `HostConfiguration` from
validation_upgrade_frequency to -//-_cooldown.

As was already pointed out in #4460 the existing name is a misnomer, the
member actually represents a minimum time period between upgrades, which
is neatly expressed by a word cooldown.

I've been planning this rename already for some time and the term is
already used in paras module:

Sergei Shulepov 4d76878759 configuration: Unified consistency checks (#4581)
This commit refactors the consistency checks. Instead of each individual
setter performs its checks locally, we delegate those checks to the
already existing function `check_consistency`. This removes duplication
and simplifies the logic.

A motivating example of this one is the next PR in the stack that will
introduce a check for a field, which validity depends on the validity of
other two fields. Without this refactoring we will have to place a check
not only to the field in question, but also to the other two fields so
that if they are changed they do not violate consistency criteria. It's
easy to imagine how this can go unwieldy with the number of checks.

This also adds a test that verifies that the default chain spec host
configuration is consistent.

Robert Klotzner 0349595894 Better logs and metrics on PoV fetching. (#4593) 2021-12-24 08:11:29 +00:00
Bastian Köcher b409837b70 Fix checking for the ParachainHost runtime api (#4594)
The function `has_api` checks that the api + version matches, which
isn't true anymore after bumping the version. The fix is to just compare
the runtime api version being at least `1`.

Bastian Köcher 97506a15c9 runtime-api: Fix runtime version checking (#4595)
The runtime version check `runtime_version <= version` was wrong, it
needs to be `>=`. Besides that the `WIDELY_DEPLOYED_API_VERSION` is
removed. The runtime version is already cached, aka we don't always call
into the runtime when requesting the runtime version. So, there is no
need to "optimize" this.

Robert Klotzner 846828f61c First step in implementing #4386 (#4437)
* First step in implementing https://github.com/paritytech/polkadot/issues/4386

This PR:

- Reduces MAX_UNSHARED_UPLOAD_TIME to 150ms
- Increases timeout on collation fetching to 1200ms
- Reduces limit on needed backing votes in the runtime

This PR does not yet reduce the number of needed backing votes on the
node as this can only be meaningfully enacted once the changed limit in
the runtime is live.

* Fix tests.

* Guide updates.

* Review remarks.

* Bump minimum required backing votes to 2 in runtime.

* Make sure node side code won't make runtime vomit.

* cargo +nightly fmt

Sergei Shulepov 1493fed1ed PVF validation host: do not alter niceness (#4525)
We wanted to change niceness to accomodate the fact that some of the
preparation tasks are low priority. For example, when a node sees that
there is a new para was onboarded the node may start preparing right
away. Since all other activities are more important, such as network I/O
or validation of the backed candidates and preparation of the
immediatelly needed PVFs.

However, it turned out that this approach does not work: generally
non-root processes can only decrease niceness and they cannot increase
it to the previous value, as was assumed by the code.

Apart from that, https://github.com/paritytech/polkadot/pull/4123
assumes all PVFs are prepared in the same way. Specifically, that if a
PVF preparation failed before, then PVF pre-checking will also report
that it was failed, even though it could happen that preparation failed
due to being low-priority. In order to avoid such cases, we decided to
simplify the whole preparation model. Preparation under low priority
does not work well with that.

Closes https://github.com/paritytech/polkadot/issues/4520

Sergei Shulepov 2ccbf38b85 pvf-precheck: teach runtime-api to work with versions (#4510)
As part of #3211 we will need to add a couple of runtime APIs. That
change is coming in a following PR.

The runtime API for pre-checking will be introduced with a version bump
for `ParachainHost`. This commit prepares the ground for that change,
by introducing a error condition that signals that the given API is not
supported.
