From 2da96fb50515e17f1114831ccfd81a945cbd65c7 Mon Sep 17 00:00:00 2001 From: matheus1lva Date: Wed, 19 Nov 2025 21:22:00 -0300 Subject: [PATCH] refactor: simplify Kong data handling and add graceful database fallback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add graceful handling when KONG_POSTGRES_DSN is not configured - Remove Kong data refresh from metadata scheduler (APY data now stored during indexing) - Clean up unused Kong data mutex code and fetchKongVaultDataFromDB function - Add database connection checks to prevent panics when DB is unavailable - Simplify debt assignment logic with cleaner if-else-if chain and early break - Fix Kong TVL conversion to prevent precision loss for large values - Optimize strategy processing by removing unnecessary error handling overhead 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- external/vaults/models.go | 11 ++++ .../vaults/route.vaults.one.simplified.go | 56 +++++++------------ internal/fetcher/vaults.go | 26 ++++++--- internal/indexer/indexer.kong.go | 6 ++ internal/models/vaults.go | 3 +- internal/storage/elem.vaults.go | 13 +---- 6 files changed, 58 insertions(+), 57 deletions(-) diff --git a/external/vaults/models.go b/external/vaults/models.go index 89bc040f4..6a3712254 100755 --- a/external/vaults/models.go +++ b/external/vaults/models.go @@ -261,6 +261,7 @@ type TExternalVault struct { Info TExternalVaultInfo `json:"info,omitempty"` FeaturingScore float64 `json:"featuringScore"` // Computing only PricePerShare *bigNumber.Int `json:"pricePerShare"` + Debts []models.TKongDebt `json:"debts"` } /************************************************************************************************** @@ -368,6 +369,15 @@ func ApplyKongData(externalVault *TExternalVault, vault models.TVault) { externalVault.APR.Fees.Management = bigNumber.NewFloat(float64(managementFee) / 10000.0) externalVault.APR.Fees.Performance = bigNumber.NewFloat(float64(performanceFee) / 10000.0) + for _, strategyAddress := range kongData.StrategyAddresses { + strategy, ok := storage.GuessStrategy(vault.ChainID, strategyAddress) + if !ok { + continue + } + + externalVault.Strategies = append(externalVault.Strategies, CreateExternalStrategy(strategy)) + } + // Future: Apply other kong data // applyKongPrices(externalVault, kongData) // applyKongAPY(externalVault, kongData) @@ -485,6 +495,7 @@ func CreateExternalVault(vault models.TVault) (TExternalVault, error) { Description: vault.Metadata.Description, Category: fetcher.BuildVaultCategory(vault, strategies), PricePerShare: vault.LastPricePerShare, + Debts: vault.Debts, Details: TExternalVaultDetails{ IsRetired: vault.Metadata.IsRetired, IsHidden: vault.Metadata.IsHidden, diff --git a/external/vaults/route.vaults.one.simplified.go b/external/vaults/route.vaults.one.simplified.go index eaa909eeb..9c45282d9 100755 --- a/external/vaults/route.vaults.one.simplified.go +++ b/external/vaults/route.vaults.one.simplified.go @@ -8,6 +8,7 @@ import ( "github.com/ethereum/go-ethereum/common" "github.com/gin-gonic/gin" + "github.com/yearn/ydaemon/common/bigNumber" "github.com/yearn/ydaemon/internal/models" "github.com/yearn/ydaemon/internal/storage" ) @@ -100,13 +101,7 @@ func (y Controller) GetSimplifiedVault(c *gin.Context) { if newVault.APR.NetAPR != nil { // APR.NetAPR.Float64() returns (float64, big.Accuracy), not an error // big.Accuracy is an int8 type that indicates precision, not an error - var acc interface{} - APRAsFloat, acc = newVault.APR.NetAPR.Float64() - if acc != nil { - // Log a warning but continue with the calculated value - c.Error(fmt.Errorf("reduced precision when converting APR to float for vault %s: %v", - address.String(), acc)) - } + APRAsFloat, _ = newVault.APR.NetAPR.Float64() } // Check for potential arithmetic overflow due to very large values @@ -137,40 +132,29 @@ func (y Controller) GetSimplifiedVault(c *gin.Context) { newVault.FeaturingScore = newVault.FeaturingScore * 1e18 } - vaultStrategiesMap, vaultStrategies := storage.ListStrategiesForVault(currentVault.ChainID, common.HexToAddress(newVault.Address)) - if len(vaultStrategies) == 0 && len(vaultStrategiesMap) == 0 { - // Log a warning but continue - no strategies is a valid scenario - c.Error(fmt.Errorf("no strategies found for vault %s on chain %d", - address.String(), chainID)) - } - - // Initialize the strategies array with appropriate capacity to avoid reallocations - newVault.Strategies = make([]TExternalStrategy, 0, len(vaultStrategies)) - - // Process strategies with context awareness + // Fetch and process strategies with context awareness + vaultStrategies, _ := storage.ListStrategiesForVault(chainID, address) + newVault.Strategies = []TExternalStrategy{} for _, strategy := range vaultStrategies { - // Try to convert the strategy, capturing any errors - var strategyWithDetails TExternalStrategy - func() { - // Use a deferred recover to handle any panics during conversion - defer func() { - if r := recover();
