Update commitments with support for non-standard units#624
Conversation
…non-standard units (waiting for release)
📝 WalkthroughWalkthroughThe changes introduce commitment unit validation in the syncer, add Prometheus metrics for tracking sync operations and unit mismatches, implement global request ID propagation from reservation annotations, and update dependency versions. A syncer monitor is instantiated at startup and passed to the syncer during initialization. Changes

240-243: Consider usingmaps.Copyfor merging the skipped UUIDs.Per coding guidelines, prefer
maps.Copyover iteratively copying map entries.♻️ Suggested refactor
// Also include skipped commitments - don't delete their CRDs - for uuid := range commitmentResult.skippedUUIDs { - activeCommitments[uuid] = true - } + maps.Copy(activeCommitments, commitmentResult.skippedUUIDs)You'll need to add
"maps"to the imports.As per coding guidelines: "Use

- Around line 111-123: The code calls a non-existent method
UnitMebibytes.MultiplyBy; replace that logic by calling
liquid.UnitMebibytes.Base() to get (baseUnit, multiplier), set unit = baseUnit
(or liquid.UnitNone on error), and compute any scaled value by multiplying
groupData.SmallestFlavor.MemoryMB by multiplier before assigning into resources;
update references around UnitMebibytes, Unit.Base(),
groupData.SmallestFlavor.MemoryMB, and the resources[resourceName] assignment to
use baseUnit and the computed scaled value.

go-api-declarations liquid Unit MultiplyBy method sapcc
💡 Result:
In github.com/sapcc/go-api-declarations/liquid, there is no Unit.MultiplyBy method. Instead, unit conversion is modeled via:
func (u Unit) Base() (Unit, uint64)which returns the base unit plus a multiplier to convert values inuinto that base unit. For all binary-size units (KiB,MiB, …), the base unit isB(bytes); otherwise it returns(u, 1). [1][2]
Multiplier mapping (from Base()): KiB=1<<10, MiB=1<<20, GiB=1<<30, TiB=1<<40, PiB=1<<50, EiB=1<<60. [2]
How to “multiply by” in practice:
base, mul := u.Base()
valueInBase := value * mul[1][2]
Sources: [1] [2]
Fix non-existent MultiplyBy API call — use Unit.Base() instead.
The liquid.UnitMebibytes.MultiplyBy() method does not exist in go-api-declarations/liquid. Use the Base() method to convert units:
baseUnit, multiplier := liquid.UnitMebibytes.Base()
// Then use: groupData.SmallestFlavor.MemoryMB * multiplier🤖 Prompt for AI Agents
