Merge pull request #10812 from Mic92/build-perf 
Remove 100s of CPU time (10%) from build times (1465s -> 1302s)
 2024-05-31 13:28:24 +02:00

473d2d56fc Remove 100s of CPU time (10%) from build times (1465s -> 1302s) 
Result's from Mic92's framework 13th Gen Intel Core i7-1360P:

Before: 3595.92s user 183.01s system 1360% cpu 4:37.74 total
After: 3486.07s user 168.93s system 1354% cpu 4:29.79 total

I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.

Before:

This turns errors like:

error: flake output attribute 'hydraJobs' is not a derivation or path

into errors like:

error: expected flake output attribute 'hydraJobs' to be a derivation or
path but found a set: { binaryTarball = «thunk»; build = «thunk»; etc> }

This change affects all InstallableFlake commands.

`*StoreConfig` -> `Store*` rather than skipping the middle step too.

f71b4da0b3 Factor our connection code for worker proto like serve proto 
This increases test coverage, and gets the worker protocol ready to be
used by Hydra.

Why don't we just try to use the store interface in Hydra? Well, the
problem is that the store interface works on connection pools, with each
opreation getting potentially a different connection, but the way temp
roots work requires that we keep one logical "transaction" (temp root
session) using the same connection.

The longer-term solution probably is making connections themselves
implement the store interface, but that is something that builds on
this, so I feel OK that this is not churn in the wrong direction.

Fixes #9584

8ebd99c74e Back in enum values for BuildMode serializer 
We don't want to rely on how C assigns numbers for enums in the wire
format. Sure, this is totally determined by the ABI, but it obscures the
code and makes it harder to safely change the enum definition (should we
need to) without accidentally breaking the wire format.

eeb89c28b0 Worker proto use proper serialiser for BuildMode 
Do this instead of an unchecked cast

I redid this to use the serialisation framework (including a unit test),
but I am keeping the reference to credit Jade for spotting the issue.
