From c7fb4b3a2a309e6939fbe0c3a86b2d5f160cfecb Mon Sep 17 00:00:00 2001 From: martonp Date: Tue, 10 Feb 2026 16:09:31 -0500 Subject: [PATCH 1/4] oracle: Refactor sources into subpackage and add quota tracking Move source definitions into oracle/sources/ with provider implementations in oracle/sources/providers/ and shared utilities in oracle/sources/utils/. This separates the source abstraction from the oracle core logic. Also adds quota tracking for each of the sources. --- oracle/.gitignore | 1 - oracle/diviner.go | 66 +- oracle/diviner_test.go | 248 +++-- oracle/oracle.go | 107 +- oracle/oracle_test.go | 8 +- oracle/sources.go | 446 -------- oracle/sources/interface.go | 58 ++ oracle/sources/providers/bitcore.go | 70 ++ oracle/sources/providers/blockcypher.go | 108 ++ oracle/sources/providers/coinmarketcap.go | 118 +++ oracle/sources/providers/coinpaprika.go | 59 ++ oracle/sources/providers/dcrdata.go | 63 ++ oracle/sources/providers/firo.go | 34 + oracle/sources/providers/live_test.go | 268 +++++ oracle/sources/providers/mempool.go | 52 + oracle/sources/providers/source_test.go | 220 ++++ oracle/sources/providers/tatum.go | 131 +++ oracle/sources/utils/http.go | 96 ++ oracle/sources/utils/quota_tracker.go | 279 +++++ oracle/sources/utils/quota_tracker_test.go | 481 +++++++++ oracle/sources/utils/unlimited.go | 66 ++ oracle/sources/utils/unlimited_test.go | 180 ++++ oracle/sources_test.go | 1061 -------------------- 23 files changed, 2527 insertions(+), 1693 deletions(-) delete mode 100644 oracle/.gitignore delete mode 100644 oracle/sources.go create mode 100644 oracle/sources/interface.go create mode 100644 oracle/sources/providers/bitcore.go create mode 100644 oracle/sources/providers/blockcypher.go create mode 100644 oracle/sources/providers/coinmarketcap.go create mode 100644 oracle/sources/providers/coinpaprika.go create mode 100644 oracle/sources/providers/dcrdata.go create mode 100644 oracle/sources/providers/firo.go create mode 100644 oracle/sources/providers/live_test.go create mode 100644 oracle/sources/providers/mempool.go create mode 100644 oracle/sources/providers/source_test.go create mode 100644 oracle/sources/providers/tatum.go create mode 100644 oracle/sources/utils/http.go create mode 100644 oracle/sources/utils/quota_tracker.go create mode 100644 oracle/sources/utils/quota_tracker_test.go create mode 100644 oracle/sources/utils/unlimited.go create mode 100644 oracle/sources/utils/unlimited_test.go delete mode 100644 oracle/sources_test.go diff --git a/oracle/.gitignore b/oracle/.gitignore deleted file mode 100644 index cc2ddc8..0000000 --- a/oracle/.gitignore +++ /dev/null @@ -1 +0,0 @@ -coinpap2000.json diff --git a/oracle/diviner.go b/oracle/diviner.go index 173f4c8..6fd7b02 100644 --- a/oracle/diviner.go +++ b/oracle/diviner.go @@ -9,32 +9,22 @@ import ( "github.com/decred/slog" + "github.com/bisoncraft/mesh/oracle/sources" "github.com/bisoncraft/mesh/tatanka/pb" ) -// fetcher returns either a list of price updates or a list of fee rate updates. -type fetcher func(ctx context.Context) (any, error) -

scheduling based on mesh quotas Updates the algorithm to determine when to perform the next fetch for each source to be based on the quotas of the entire mesh. The sustainable fetch rate of the entire network is calculated, and the entire network can deterministically determine which node should perform the next fetch. Additionally, an Oracle Snapshot function is added which will allow the admin tools to view the state of the oracle. --- oracle/buckets.go | 227 ++++++++++ oracle/diviner.go | 211 ++++-----

new(big.Int).SetBytes(feeRateUpdate.FeeRate) From a4d4006a9369fbb9557594a81c6bc0c2a78a1bfb Mon Sep 17 00:00:00 2001 From: martonp Date: Tue, 10 Feb 2026 16:15:55 -0500 Subject: [PATCH 4/4] tatankactl: Refactor TUI with oracle and connection views Replace the CLI-based tatankactl with an interactive bubbletea TUI. Add oracle source status view with per-source detail screens showing schedule, fetch order, quotas, and price/fee rate contributions. Add aggregated data view with drill-down into individual tickers. --- cmd/tatanka/.!28982!tatanka | 0 cmd/tatankactl/api.go | 344 +++++++++++ cmd/tatankactl/connections.go | 162 +++++ cmd/tatankactl/diff.go | 171 ++++++ cmd/tatankactl/main.go | 659 +++++++-------------- cmd/tatankactl/menu.go | 71 +++ cmd/tatankactl/oracle_aggregated.go | 146 +++++ cmd/tatankactl/oracle_aggregated_detail.go | 152 +++++ cmd/tatankactl/oracle_detail.go | 280 +++++++++ cmd/tatankactl/oracle_view.go | 171 ++++++ cmd/tatankactl/section.go | 235 ++++++++ cmd/tatankactl/styles.go | 147 +++++ go.mod | 19 +- go.sum | 41 +- 14 files changed, 2152 insertions(+), 446 deletions(-) create mode 100755 cmd/tatanka/.!28982!tatanka create mode 100644 cmd/tatankactl/api.go create mode 100644 cmd/tatankactl/connections.go create mode 100644 cmd/tatankactl/diff.go create mode 100644 cmd/tatankactl/menu.go create mode 100644 cmd/tatankactl/oracle_aggregated.go create mode 100644 cmd/tatankactl/oracle_aggregated_detail.go create mode 100644 cmd/tatankactl/oracle_detail.go create mode 100644 cmd/tatankactl/oracle_view.go create mode 100644 cmd/tatankactl/section.go create mode 100644 cmd/tatankactl/styles.go diff --git a/cmd/tatanka/.!28982!tatanka b/cmd/tatanka/.!28982!tatanka new file mode 100755 index 0000000..e69de29 diff --git a/cmd/tatankactl/api.go b/cmd/tatankactl/api.go new file mode 100644 index 0000000..09c2a7c --- /dev/null +++ b/cmd/tatankactl/api.go @@ -0,0 +1,344 @@ +package main + +import ( + "encoding/json" + "fmt" + "net/url" + "sort" + "strings" + "sync" + "time" + + tea "github.com/charmbracelet/bubbletea" + "github.com/gorilla/websocket" + "github.com/bisoncraft/mesh/oracle" + "github.com/bisoncraft/mesh/tatanka/admin" +) + +// --- Navigation messages --- + +type viewID int + +const ( + viewMenu viewID = iota + viewConnections + viewDiff + viewOracleSources + viewOracleDetail + viewOracleAggregated + viewAggregatedDetail +) + +type navigateMsg struct{ view viewID } +type navigateBackMsg struct{} +type navigateToDiffMsg struct{ node admin.NodeInfo } +type navigateToSourceDetailMsg struct { + sourceName string +} +type navigateToAggregatedDetailMsg struct { + dataType oracle.DataType + key string // ticker or network name +} + +// --- Data messages --- + +type adminStateMsg struct { + state *admin.AdminState +} + +type wsConnectedMsg struct{} +type wsErrorMsg struct{ err error } +type wsReconnectMsg struct{} + +// oracleSnapshotMsg is received on WS connect as full state. +type oracleSnapshotMsg oracle.OracleSnapshot + +// oracleUpdateMsg is a partial diff received as oracle_update. +type oracleUpdateMsg oracle.OracleSnapshot + +// renderTickMsg triggers periodic re-rendering while oracle views are active. +type renderTickMsg time.Time + +// --- Shared helpers --- + +func navBack() tea.Cmd { + return func() tea.Msg { return navigateBackMsg{} } +} + +func sortedKeys[M ~map[string]V, V any](m M) []string { + keys := make([]string, 0, len(m)) + for k := range m { + keys = append(keys, k) + } + sort.Strings(keys) + return keys +} + +// --- Shared oracle data helpers --- + +func newOracleSnapshot() *oracle.OracleSnapshot { + return &oracle.OracleSnapshot{ + Prices: make(map[string]*oracle.SnapshotRate), + FeeRates: make(map[string]*oracle.SnapshotRate), + Sources: make(map[string]*oracle.SourceStatus), + } +} + +func getOrCreateSource(d *oracle.OracleSnapshot, name string) *oracle.SourceStatus { + src, ok := d.Sources[name] + if !ok { + src = &oracle.SourceStatus{ + Fetches24h: make(map[string]int), + Quotas: make(map[string]*oracle.Quota), + } + d.Sources[name] = src + } + return src +} + +func getOrCreateRate(m map[string]*oracle.SnapshotRate, key string) *oracle.SnapshotRate { + r, ok := m[key] + if !ok { + r = &oracle.SnapshotRate{ + Contributions: make(map[string]*oracle.SourceContribution), + } + m[key] = r + } + return r +} + +// mergeSnapshot applies a partial oracle.OracleSnapshot to the shared state. +func mergeSnapshot(d *oracle.OracleSnapshot, msg oracle.OracleSnapshot) { + if msg.NodeID != "" { + d.NodeID = msg.NodeID + } + + for name, s := range msg.Sources { + src := getOrCreateSource(d, name) + if s.LastFetch != nil { + src.LastFetch = s.LastFetch + } + if s.NextFetchTime != nil { + src.NextFetchTime = s.NextFetchTime + } + if s.MinFetchInterval != nil { + src.MinFetchInterval = s.MinFetchInterval + } + if s.NetworkSustainableRate != nil { + src.NetworkSustainableRate = s.NetworkSustainableRate + } + if s.NetworkSustainablePeriod != nil { + src.NetworkSustainablePeriod = s.NetworkSustainablePeriod + } + if s.NetworkNextFetchTime != nil { + src.NetworkNextFetchTime = s.NetworkNextFetchTime + } + if s.NextFetchTime != nil { + // Schedule updates from the diviner always carry error + // state.
