feat(proof-data-handler): exclude batches without object file in GCS #2980

Merged

What ❔

/tee/proof_inputs endpoint no longer returns batches that have no corresponding object file in Google Cloud Storage for an extended period.

Why ❔

TEE's proof-data-handler on mainnet was flooded with warnings.

Since the recent mainnet's 24.25.0 redeployment, we've been flooded with warnings for the proof-data-handler on mainnet (the warnings are actually not fatal in this context):

Failed request with a fatal error

(...)

Blobs for batch numbers 490520 to 490555 not found in the object store. Marked as unpicked.

The issue is caused by the code behind the /tee/proof_inputs endpoint (which is equivalent to the /proof_generation_data endpoint) – it finds the next batch to send to the requesting tee-prover by looking for the first batch that has a corresponding object in the Google object store. As it skips over batches that don’t have the objects, it logs Failed request with a fatal error for each one (unless the skipped batch was successfully proven, in which case it doesn’t log the error). This happens with every request the tee-prover sends, which is why we're getting so much noise in the logs.

One possible solution is to flag the problematic batches as permanently_ignored, like Thomas did before on mainnet.

@popzxc, I remember you mentioned not to ask for code reviews this wave, but you're probably the most familiar with this code (along with @slowli). So, if you could make an exception this time, I’d really appreciate it. If you're busy, no worries – feel free to ignore, and I’ll ask @RomanBrodetski to find someone else. Thanks!

@pbeza to be honest I don't fully follow this solution. I understand what we are trying to do (mark older unresolved jobs as skipped), but I'm not sure I understand the Why here. We can discuss over a huddle or async

JFYI: This PR is on hold because the code it is based on was recently radically redesigned/refactored here: #3017. This PR may be cherry-picked/revisited once #3017 is merged into main.

We already depend on zksync_types, which re-exports a substantial part
of basic types.

@slowli @haraldh I just retested everything manually to ensure that transitioning to the permanently_ignored state works correctly when there are no object files (you can't imagine how time-consuming and painful it is to reproduce). Everything seems to be working perfectly. Ready to merge from my perspective. 🫡
