Root cause of the balances-test hang in pezkuwi-wallet-android (silent
for over an hour, cancelled multiple times before finding this):
every single chain_id in blocked-chains.json was stale - none matched
anything in Nova's current chains.json (last_updated 2026-02-11, ~5
months of upstream chain-id drift since). The blacklist mechanism
silently no-opped for all 6 entries, so none of the chains it was
meant to exclude were actually excluded.
With the blacklist ineffective, several chains with genuinely dead RPC
endpoints (confirmed live 2026-07-08: 3DPass, Curio, Quartz, Subsocial
- 502s, timeouts, SSL failures) stayed in the merged output. The
Android app's ChainConnection/NodeAutobalancer has no backoff/circuit
breaker for dead endpoints, so it retried them in an extremely tight
loop (~1 attempt/second, 1500-1800+ attempts observed in a 25 minute
window per chain) - burning resources indefinitely and starving the
app's actual chain-sync/test work, which is what made the Android CI
job hang for over an hour with zero progress.
Fix: re-verified and corrected all chain_ids (matching by current
name against live chains.json), added 3DPass/Curio/Subsocial which
weren't blacklisted before, dropped entries for chains no longer
present upstream at all (Passet Hub Testnet, Darwinia Crab, DeepBrain,
Exosama - nothing to block, kept them as historical noise otherwise).
Also added a stale-blacklist warning to sync_from_nova.py: it now
tracks which blocked chain_ids actually matched something in Nova's
current chains across all versions, and prints a warning listing any
that didn't - so this exact silent drift is caught at sync time going
forward instead of rotting unnoticed for another five months.
Android's BalancesIntegrationTest CI fetches this fixture directly
from raw.githubusercontent.com/.../master/tests/chains_for_testBalance.json,
but it never existed in this repo's output - only chains/, xcm/,
icons/, and staking/ were ever synced from nova-base by
sync_from_nova.py. This is why "Run balances tests" in
pezkuwi-wallet-android has been failing (FileNotFoundException) even
after fixing its CI infra and instrumentation-runner issues.
Only this one fixture is published from nova-base/tests/, not the
rest of that directory (upstream's own pytest suite for validating
its chains.json output, unused by anything in this repo or its
consumers).
- Created pezkuwi-overlay/config/global_config_overlay.json (source B)
with stakingApiOverrides for Pezkuwi SubQuery + prod API URLs
- Updated sync_from_nova.py with sync_config() function
Merges: nova-base/global + nova-base/staking (A) + overlay (B) → staking/ (C)
- Same merge pattern as chains, XCM, and icons
- Add sync_from_nova.py script to merge Nova chains with Pezkuwi overlay
- Add GitHub Action for daily auto-sync
- Sync all chains from nova-base (includes Polkadot Coretime and other missing chains)
- Pezkuwi chains appear first and take priority
This fixes DOT swap crash caused by missing Polkadot Coretime chain.
