Automated behaviors (\"from now on when X\", \"each time X\", \"whenever X\", \"before/after X\") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions (\"allow X\", \"add permission\", \"move permission to\"), env vars (\"set X=Y\"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: \"allow npm commands\", \"add bq permission to global settings\", \"move permission to user settings\", \"set DEBUG=true\", \"when claude stops show X\". For simple settings like theme/model, suggest the /config command.\n- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: \"rebind ctrl+s\", \"add a chord shortcut\", \"change the submit key\", \"customize keybindings\".\n- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.\n- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.\n- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. \"check the deploy every 5 minutes\", \"keep running /babysit-prs\"). Do NOT invoke for one-off tasks.\n- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run (\"run this once at 3pm\", \"remind me to check X tomorrow\").\n- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).\nTRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.\nSKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.\n- frontend-design:frontend-design: Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\n- init: Initialize a new CLAUDE.md file with codebase documentation\n- review: Review a pull request\n- security-review: Complete a security review of the pending changes on the current branch","skillCount":11,"isInitial":true},"type":"attachment","uuid":"cb199907-b802-4f9f-bd34-0a8c0ca1825a","timestamp":"2026-05-12T09:57:19.291Z","userType":"external","entrypoint":"cli","cwd":"/Users/jan/prg/ClusterCockpit/cc-backend","sessionId":"2c7fd178-d9ee-4371-8268-f1b242d02fd5","version":"2.1.126","gitBranch":"release/v1.5"}

This\n10\tshould not take long. For optimal database performance after the migration it is\n11\trecommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`\n12\tand `VACUUM` commands. Depending on your database size (more then 40GB) the\n13\t`VACUUM` may take up to 2h. You can also run the `ANALYZE` command manually.\n14\tWhile we are confident that the memory issue with the metricstore cleanup move\n15\tpolicy is fixed, it is still recommended to use delete policy for cleanup.\n16\tThis is also the default.\n17\t\n18\t## Changes in 1.5.3\n19\t\n20\t### Bug fixes\n21\t\n22\t- **OIDC role extraction**: Fixed role extraction from OIDC tokens where roles\n23\t  were not correctly parsed from the token claims. Roles are now always\n24\t  requested from the token regardless of other configuration.\n25\t- **OIDC user sync role changes**: `SyncUser` and `UpdateUser` callbacks now\n26\t  allow all role changes, removing a restriction that prevented role updates\n27\t  during OIDC-driven user synchronization.\n28\t- **OIDC projects array**: Projects array from the OIDC token is now submitted\n29\t  and applied when syncing user attributes.\n30\t- **WAL message drops during checkpoint**: WAL writes are now paused during\n31\t  binary checkpoint creation. Previously, disk I/O contention between\n32\t  checkpoint writes and WAL staging caused over 1.4 million dropped messages\n33\t  per checkpoint cycle.\n34\t- **WAL rotation skipped for all nodes**: `RotateWALFiles` used a non-blocking\n35\t  send on a small channel. With thousands of nodes, the channel filled instantly\n36\t  and nearly all hosts were skipped, leaving WAL files unrotated. Replaced with\n37\t  a blocking send using a shared 2-minute deadline.\n38\t- **Log viewer auto-refresh**: Fixed the log viewer component not auto-refreshing\n39\t  correctly.\n40\t- **SameSite cookie setting**: Relaxed the SameSite cookie attribute to improve\n41\t  compatibility with OIDC redirect flows.\n42\t- **WAL not rotated on partial checkpoint failure**: When binary checkpointing\n43\t  failed for some hosts, WAL files for successfully checkpointed hosts were not\n44\t  rotated and the checkpoint timestamp was not advanced. Partial successes now\n45\t  correctly advance the checkpoint and rotate WAL files for completed hosts.\n46\t- **Unbounded WAL file growth**: If binary checkpointing consistently failed for\n47\t  a host, its `current.wal` file grew without limit until disk exhaustion. A new\n48\t  `max-wal-size` configuration option (in the `checkpoints` block) allows setting\n49\t  a per-host WAL size cap in bytes. When exceeded, the WAL is force-rotated.\n50\t  Defaults to 0 (unlimited) for backward compatibility.\n51\t\n52\t- **Doubleranged filter fixes**: Range filters now correctly handle zero as a\n53\t  boundary value. Improved validation and UI text for \"more than equal\" and\n54\t  \"less than equal\" range selections.\n55\t- **Lineprotocol body parsing interrupted**: Switched from `ReadTimeout` to\n56\t  `ReadHeaderTimeout` so that long-running metric submissions are no longer\n57\t  cut off mid-stream.\n58\t- **Checkpoint archiving continues on error**: A single cluster's archiving\n59\t  failure no longer aborts the entire cleanup operation. Errors are collected\n60\t  and reported per cluster.\n61\t- **Parquet row group overflow**: Added periodic flush during checkpoint\n62\t  archiving to prevent exceeding the parquet-go 32k column-write limit.\n63\t- **Removed metrics excluded from subcluster config**: Metrics removed from a\n64\t  subcluster are no longer returned by `GetMetricConfigSubCluster`.\n65\t\n66\t### MetricStore performance\n67\t\n68\t- **WAL writer throughput**: Decoupled WAL file flushing from message processing\n69\t  using a periodic 5-second batch flush (up to 4096 messages per cycle),\n70\t  significantly increasing metric ingestion throughput.\n71\t- **Improved shutdown time**: HTTP shutdown timeout reduced; metricstore and\n72\t  archiver now shut down concurrently. Overall shutdown deadline raised to\n73\t  60 seconds.\n74\t\n75\t### New features\n76\t\n77\t- **Manual checkpoint cleanup flag**: New `-cleanup-checkpoints` CLI flag\n78\t  triggers checkpoint cleanup without starting the server, useful for\n79\t  maintenance windows or automated cleanup scripts.\n80\t- **Explicit node state queries in node view**: Node health and scheduler state\n81\t  are now fetched independently from metric data for fresher status information.\n82\t\n83\t### Development tooling\n84\t\n85\t- **Make targets for formatting and linting**: New `make fmt` and `make lint`\n86\t  targets using `gofumpt` and `golangci-lint`. Configuration added in\n87\t  `.golangci.yml` and `gopls.json`.\n88\t\n89\t### New tools\n90\t\n91\t- **binaryCheckpointReader**: New utility tool (`tools/binaryCheckpointReader`)\n92\t  that reads `.wal` or `.bin` checkpoint files produced by the metricstore\n93\t  WAL/snapshot system and dumps their contents to a human-readable `.txt` file.\n94\t  Useful for debugging and inspecting checkpoint data. Usage:\n95\t  `go run ./tools/binaryCheckpointReader <file.wal|file.bin>`\n96\t\n97\t### Logging improvements\n98\t\n99\t- **Reduced tagger log noise**: Missing metrics and expression evaluation errors\n100\t  in the job classification tagger are now logged at debug level instead of\n101\t  error level.\n102\t\n103\t## Changes in 1.5.2\n104\t\n105\t### Bug fixes\n106\t\n107\t- **Memory spike in parquet writer**: Fixed memory spikes when using the\n108\t  metricstore move (archive) policy with the parquet writer. The writer now\n109\t  processes data in a streaming fashion to avoid accumulating large allocations.\n110\t- **Top list query fixes**: Fixed top list queries in analysis and dashboard\n111\t  views.\n112\t- **Exclude down nodes from HealthCheck**: Down nodes are now excluded from\n113\t  health checks in both the REST and NATS handlers.\n114\t- **Node state priority order**: Node state determination now enforces a\n115\t  priority order. Exception: idle+down results in idle.\n116\t- **Blocking ReceiveNats call**: Fixed a blocking NATS receive call in the\n117\t  metricstore.\n118\t\n119\t### Database performance\n120\t\n121\t- **Reduced insert pressure**: Bulk insert operations (node state updates, user\n122\t  and job cache syncs) now use explicit transactions and deferred inserts,\n123\t  significantly reducing write contention on the SQLite database.\n124\t- **SyncJobs wrapped in transaction**: `SyncJobs` now runs inside a transaction\n125\t  for better consistency and reduced lock contention.\n126\t- **Configurable busy timeout**: New `busy-timeout` configuration option for the\n127\t  SQLite connection. This allows tuning how long the driver waits for a locked\n128\t  database before returning an error, which improves resilience under concurrent\n129\t  write load.\n130\t- **Increased default SQLite timeout**: The default SQLite connection timeout\n131\t  has been raised to reduce spurious timeout errors under load.\n132\t- **Optimized stats queries**: Improved sortby handling in stats queries, fixed\n133\t  cache key passing, and simplified a stats query condition that caused an\n134\t  expensive unnecessary subquery.\n135\t\n136\t### MetricStore performance\n137\t\n138\t- **Sharded WAL consumer**: The WAL consumer is now sharded for significantly\n139\t  higher write throughput.\n140\t- **NATS contention fix**: Fixed contention in the metricstore NATS ingestion\n141\t  path.\n142\t\n143\t### NATS API\n144\t\n145\t- **Nodestate health checks in NATS API**: The NATS node state handler now\n146\t  performs the same metric health checks as the REST API handler, including\n147\t  per-subcluster health checks and `MonitoringStateFailed` fallback for nodes\n148\t  without health data.\n149\t\n150\t### Logging improvements\n151\t\n152\t- **Better error context**: Several repository functions now include the calling\n153\t  function name in error messages for easier diagnosis.\n154\t- **Reduced log noise**: `ErrNoRows` (no results found) is no longer logged as\n155\t  an error in `scanRow`; common \"no rows\" paths are now silent.\n156\t- **Debug-level missing metrics**: Warning about missing metrics in the metric\n157\t  store has been downgraded to debug level to reduce log noise in normal\n158\t  operation.\n159\t- **Checkpoint archiving log**: Added an informational log message when the\n160\t  metricstore checkpoint archiving process runs.\n161\t- **Auth failure context**: Auth failure log messages now include more context\n162\t  information.\n163\t\n164\t### Behavior changes\n165\t\n166\t- **DB-based metricHealth**: Replaced heuristic-based metric health with\n167\t  DB-based metric health for the node view, providing more accurate health\n168\t  status information.\n169\t- **Removed minRunningFor filter remnants**: Cleaned up remaining `minRunningFor`\n170\t  references from the GraphQL schema and query builder.\n171\t\n172\t### Frontend\n173\t\n174\t- **Streamlined statsSeries**: Unified stats series calculation and rendering\n175\t  across plot components.\n176\t- **Clarified plot titles**: Improved titles in dashboard and health views.\n177\t- **Bumped frontend dependencies**: Updated frontend dependencies to latest\n178\t  versions.\n179\t\n180\t### Dependencies\n181\t\n182\t- **cc-lib upgraded**: Updated to latest cc-lib version.\n183\t\n184\t## Known issues\n185\t\n186\t- The new dynamic memory management is not bullet proof yet across restarts.\n187\t  Buffers that are kept outside the retention period may be lost across a\n188\t  restart.

`cc-backend` version 1.5.4\n\nSupports job archive version 3 and database version 11.\n\nThis is a bugfix release of `cc-backend`, the API backend and frontend\nimplementation of ClusterCockpit.\nFor release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).\nIf you are upgrading from v1.5.1 no database migration is required.\nIf you are upgrading from v1.5.0 you need to do another DB migration. This\nshould not take long. For optimal database performance after the migration it is\nrecommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`\nand `VACUUM` commands. Depending on your database size (more then 40GB) the\n`VACUUM` may take up to 2h. You can also run the `ANALYZE` command manually.\nWhile we are confident that the memory issue with the metricstore cleanup move\npolicy is fixed, it is still recommended to use delete policy for cleanup.\nThis is also the default.\n\n## Changes in 1.5.3\n\n### Bug fixes\n\n- **OIDC role extraction**: Fixed role extraction from OIDC tokens where roles\n  were not correctly parsed from the token claims. Roles are now always\n  requested from the token regardless of other configuration.\n- **OIDC user sync role changes**: `SyncUser` and `UpdateUser` callbacks now\n  allow all role changes, removing a restriction that prevented role updates\n  during OIDC-driven user synchronization.\n- **OIDC projects array**: Projects array from the OIDC token is now submitted\n  and applied when syncing user attributes.\n- **WAL message drops during checkpoint**: WAL writes are now paused during\n  binary checkpoint creation. Previously, disk I/O contention between\n  checkpoint writes and WAL staging caused over 1.4 million dropped messages\n  per checkpoint cycle.\n- **WAL rotation skipped for all nodes**: `RotateWALFiles` used a non-blocking\n  send on a small channel. With thousands of nodes, the channel filled instantly\n  and nearly all hosts were skipped, leaving WAL files unrotated. Replaced with\n  a blocking send using a shared 2-minute deadline.\n- **Log viewer auto-refresh**: Fixed the log viewer component not auto-refreshing\n  correctly.\n- **SameSite cookie setting**: Relaxed the SameSite cookie attribute to improve\n  compatibility with OIDC redirect flows.\n- **WAL not rotated on partial checkpoint failure**: When binary checkpointing\n  failed for some hosts, WAL files for successfully checkpointed hosts were not\n  rotated and the checkpoint timestamp was not advanced. Partial successes now\n  correctly advance the checkpoint and rotate WAL files for completed hosts.\n- **Unbounded WAL file growth**: If binary checkpointing consistently failed for\n  a host, its `current.wal` file grew without limit until disk exhaustion. A new\n  `max-wal-size` configuration option (in the `checkpoints` block) allows setting\n  a per-host WAL size cap in bytes. When exceeded, the WAL is force-rotated.\n  Defaults to 0 (unlimited) for backward compatibility.\n\n- **Doubleranged filter fixes**: Range filters now correctly handle zero as a\n  boundary value. Improved validation and UI text for \"more than equal\" and\n  \"less than equal\" range selections.\n- **Lineprotocol body parsing interrupted**: Switched from `ReadTimeout` to\n  `ReadHeaderTimeout` so that long-running metric submissions are no longer\n  cut off mid-stream.\n- **Checkpoint archiving continues on error**: A single cluster's archiving\n  failure no longer aborts the entire cleanup operation. Errors are collected\n  and reported per cluster.\n- **Parquet row group overflow**: Added periodic flush during checkpoint\n  archiving to prevent exceeding the parquet-go 32k column-write limit.\n- **Removed metrics excluded from subcluster config**: Metrics removed from a\n  subcluster are no longer returned by `GetMetricConfigSubCluster`.\n\n### MetricStore performance\n\n- **WAL writer throughput**: Decoupled WAL file flushing from message processing\n  using a periodic 5-second batch flush (up to 4096 messages per cycle),\n  significantly increasing metric ingestion throughput.\n- **Improved shutdown time**: HTTP shutdown timeout reduced; metricstore and\n  archiver now shut down concurrently. Overall shutdown deadline raised to\n  60 seconds.\n\n### New features\n\n- **Manual checkpoint cleanup flag**: New `-cleanup-checkpoints` CLI flag\n  triggers checkpoint cleanup without starting the server, useful for\n  maintenance windows or automated cleanup scripts.\n- **Explicit node state queries in node view**: Node health and scheduler state\n  are now fetched independently from metric data for fresher status information.\n\n### Development tooling\n\n- **Make targets for formatting and linting**: New `make fmt` and `make lint`\n  targets using `gofumpt` and `golangci-lint`. Configuration added in\n  `.golangci.yml` and `gopls.json`.\n\n### New tools\n\n- **binaryCheckpointReader**: New utility tool (`tools/binaryCheckpointReader`)\n  that reads `.wal` or `.bin` checkpoint files produced by the metricstore\n  WAL/snapshot system and dumps their contents to a human-readable `.txt` file.\n  Useful for debugging and inspecting checkpoint data. Usage:\n  `go run ./tools/binaryCheckpointReader <file.wal|file.bin>`\n\n### Logging improvements\n\n- **Reduced tagger log noise**: Missing metrics and expression evaluation errors\n  in the job classification tagger are now logged at debug level instead of\n  error level.\n\n## Changes in 1.5.2\n\n### Bug fixes\n\n- **Memory spike in parquet writer**: Fixed memory spikes when using the\n  metricstore move (archive) policy with the parquet writer. The writer now\n  processes data in a streaming fashion to avoid accumulating large allocations.\n- **Top list query fixes**: Fixed top list queries in analysis and dashboard\n  views.\n- **Exclude down nodes from HealthCheck**: Down nodes are now excluded from\n  health checks in both the REST and NATS handlers.\n- **Node state priority order**: Node state determination now enforces a\n  priority order. Exception: idle+down results in idle.\n- **Blocking ReceiveNats call**: Fixed a blocking NATS receive call in the\n  metricstore.\n\n### Database performance\n\n- **Reduced insert pressure**: Bulk insert operations (node state updates, user\n  and job cache syncs) now use explicit transactions and deferred inserts,\n  significantly reducing write contention on the SQLite database.\n- **SyncJobs wrapped in transaction**: `SyncJobs` now runs inside a transaction\n  for better consistency and reduced lock contention.\n- **Configurable busy timeout**: New `busy-timeout` configuration option for the\n  SQLite connection. This allows tuning how long the driver waits for a locked\n  database before returning an error, which improves resilience under concurrent\n  write load.\n- **Increased default SQLite timeout**: The default SQLite connection timeout\n  has been raised to reduce spurious timeout errors under load.\n- **Optimized stats queries**: Improved sortby handling in stats queries, fixed\n  cache key passing, and simplified a stats query condition that caused an\n  expensive unnecessary subquery.\n\n### MetricStore performance\n\n- **Sharded WAL consumer**: The WAL consumer is now sharded for significantly\n  higher write throughput.\n- **NATS contention fix**: Fixed contention in the metricstore NATS ingestion\n  path.\n\n### NATS API\n\n- **Nodestate health checks in NATS API**: The NATS node state handler now\n  performs the same metric health checks as the REST API handler, including\n  per-subcluster health checks and `MonitoringStateFailed` fallback for nodes\n  without health data.\n\n### Logging improvements\n\n- **Better error context**: Several repository functions now include the calling\n  function name in error messages for easier diagnosis.\n- **Reduced log noise**: `ErrNoRows` (no results found) is no longer logged as\n  an error in `scanRow`; common \"no rows\" paths are now silent.\n- **Debug-level missing metrics**: Warning about missing metrics in the metric\n  store has been downgraded to debug level to reduce log noise in normal\n  operation.\n- **Checkpoint archiving log**: Added an informational log message when the\n  metricstore checkpoint archiving process runs.\n- **Auth failure context**: Auth failure log messages now include more context\n  information.\n\n### Behavior changes\n\n- **DB-based metricHealth**: Replaced heuristic-based metric health with\n  DB-based metric health for the node view, providing more accurate health\n  status information.\n- **Removed minRunningFor filter remnants**: Cleaned up remaining `minRunningFor`\n  references from the GraphQL schema and query builder.\n\n### Frontend\n\n- **Streamlined statsSeries**: Unified stats series calculation and rendering\n  across plot components.\n- **Clarified plot titles**: Improved titles in dashboard and health views.\n- **Bumped frontend dependencies**: Updated frontend dependencies to latest\n  versions.\n\n### Dependencies\n\n- **cc-lib upgraded**: Updated to latest cc-lib version.\n\n## Known issues\n\n- The new dynamic memory management is not bullet proof yet across restarts.\n  Buffers that are kept outside the retention period may be lost across a\n  restart. We will fix that in a subsequent patch release.\n- To use the new log viewer (which is only working when starting cc-backend with\n  systemd) in the admin interface the user under which the cc-backend process is\n  running has to be allowed to execute the journalctl command.\n- The user configuration keys for the ui have changed. Therefore old user\n  configuration persisted in the database is not used anymore. It is recommended\n  to configure the metrics shown in the ui-config section and remove all records\n  in the table after the update.\n- Currently energy footprint metrics of type energy are ignored for calculating\n  total energy.\n- With energy footprint metrics of type power the unit is ignored and it is\n  assumed the metric has the unit Watt.\n\n## Changes in 1.5.1\n\n### Database\n\n- **New migration (version 11)**: Optimized database index count and added covering indexes for stats queries for significantly improved query performance\n- **Migration 9 fix**: Removed redundant indices from migration 9 that are superseded by migration 11\n- **Optional DB optimization flag**: Added `-optimize-db` CLI flag to run `ANALYZE` on demand; removed automatic ANALYZE on startup\n- **Selective stats queries**: Stats queries are now selective, reducing unnecessary computation\n- **User list paging**: Added paging support to the user list for better scalability\n- **SQLite configuration hardening**: Sanitized SQLite configuration with new configurable options; fixes large heap allocations in the SQLite driver\n- **Query cancellation**: Long-running database queries can now be cancelled\n- **Resource leak fix**: Added missing `defer Close()` calls for all query result sets\n\n### Bug fixes\n\n- **Segfault when taggers misconfigured**: Fixed crash when `enable-job-taggers` is set but tagger rule directories are missing\n- **GroupBy stats query complexity**: Reduced complexity for `groupBy` statistics queries\n- **Ranged filter conditions**: Fixed GT and LT conditions in ranged filters\n- **Energy filter preset**: Reduced energy filter preset to a more practical default\n- **JSON validity check**: Fixed wrong field being checked for JSON validity\n- **Tagger float rounding**: Fixed rounding of floats in tagger messages\n- **Node view null safety**: Added null-safe checks in node view to prevent runtime errors\n- **Public dashboard null safety**: Added null-safe checks in the public dashboard to prevent runtime errors\n\n### Frontend\n\n- **Bumped patch versions**: Updated frontend dependencies to latest patch versions\n\n### Documentation\n\n- **New DB config options**: Added new database configuration options to README\n\n---\n\n_The sections below document all features and changes introduced in the 1.5.0 major release, which 1.5.1 is based on._\n\n## Breaking changes\n\n### Configuration changes\n\n- **JSON attribute naming**: All JSON configuration attributes now use `kebab-case`\n  style consistently (e.g., `api-allowed-ips` instead of `apiAllowedIPs`).\n  Update your `config.json` accordingly.\n- **Removed `disable-archive` option**: This obsolete configuration option has been removed.\n- **Removed `clusters` config section**: The separate clusters configuration section\n  has been removed. Cluster information is now derived from the job archive.\n- **`apiAllowedIPs` is now optional**: If not specified, defaults to not\n  restricted.\n\n### Architecture changes\n\n- **Web framework replaced**: Migrated from `gorilla/mux` to `chi` as the HTTP\n  router. This should be transparent to users but affects how middleware and\n  routes are composed.
