Release notes

v0.12.1

  • Jobs with no queue are now released during graceful shutdown (thanks @olexiyb)

v0.12.0

  • Run shutdown actions in reverse order (rather than parallel) - more stable release
  • When an error occurs with the new job listener, reconnection attempts now follow an exponential back-off pattern
  • Allow using Node.js time rather than PostgreSQL time (particularly useful for tests)
  • Refactoring of some cron internals
  • Add noPreparedStatements to the docs

v0.11.4

  • Fixes bug in crontab day-of-week check
  • Exposes parseCronItem helper

v0.11.3

  • Restores Logger export accidentally removed in v0.11.0

v0.11.2

  • Added support for wider range of @types/pg dependency

v0.11.1

  • Handles unexpected errors whilst PostgreSQL client is idle

v0.11.0

  • Export getCronItems so library-mode users can watch the crontab file
  • Replace Logger with new @graphile/logger module

v0.10.0

  • No longer exit on SIGPIPE (Node will swallow this error code)
  • Fix issue with error handling on PostgreSQL restart or pg_terminate_backend
  • Fix a potential unhandled promise rejection

v0.9.0

  • New (experimental) "cron" functionality for regularly scheduled jobs
  • Replace jobs ordering index for improved performance (thanks @ben-pr-p)
    • NOTE: this migration might take a moment if you have a large jobs table
  • New events system lets you monitor what's going on inside Graphile Worker
  • New job_key_mode setting; see README for full details, but summary:
    • defaults to replace (existing behavior, i.e. debouncing)
    • if set to preserve_run_at it will preserve run_at which effectively changes it from debouncing to throttling
    • if set to unsafe_dedupe it will not update the attributes when an existing job with that job key exists, even if that job is already running
  • remove_job now prevents locked jobs from running again on error (and removes their key)
  • Dependency updates

v0.8.1

  • Fix issue with cyclic requires in watch mode

v0.8.0

  • Track revision count for jobs (thanks @lukeramsden)
  • "Forbidden flags" feature for rate limiting (thanks @ben-pr-p)
  • Fix incorrect description of priority - numerically smaller numbers run first (thanks @ben-pr-p)
  • Add support for PG* PostgreSQL envvars

v0.7.2

  • Add --no-prepared-statements flag to allow disabling of prepared statements for pgBouncer compatibility.
  • Fix issue in watch mode where files require()d from inside a task are cached permanently.

(v0.7.0 and v0.7.1 had issues with the experimental watch mode enhancements, so were never upgraded to @latest.)

v0.6.1

  • Official Docker image (thanks @madflow)

v0.6.0

  • Use target es2018 for TypeScript (Node v10 supports everything we need) (thanks @keepitsimple)
  • When task promise is rejected with non-Error, use a fallback (thanks @parker-torii)
  • Support pg@8.x and hence Node v14 (thanks @purge)
  • Fix mistake in README
  • General maintenance

v0.5.0

New "Administrative functions", ability to rename graphile_worker schema, and significant overhaul of the codebase in preparation for going to v1.0.

v0.5.0 improvements:

  • Added "Administrative functions" to complete, reschedule or fail jobs in bulk (good for UIs)
  • Added noHandleSignals option to disable our signal handling (if you enable this, make sure you use your own signal handling!)
  • Ability to rename graphile_worker schema
  • Added cosmiconfig for configuration (very few options support this currently)
  • Decrease already negligible chance of worker ID collision (use crypto.randomBytes() rather than Math.random())

v0.5.0 breaking changes:

CLI users: no breaking changes.

Library users: none of the documented (in the README) APIs are affected, except runTaskListOnce and some tiny tweaks to TypeScript types.

The ability to override the SQL schema means that everything in the codebase needs to know this setting. To achieve this:

  • all major APIs now accept options as a configuration parameter
  • where this was optional before it is now required
  • where options was not the first argument, it has been moved to the first argument (for consistency)

As such the following APIs (most of which are internal) have been changed:

  • getTasks(taskPath, watch, logger) -> getTasks(options, taskPath, watch)
  • runTaskList(tasks, pgPool, options?) -> runTaskList(options, tasks, pgPool)
  • runTaskListOnce(tasks, client, options?) -> runTaskList(options, tasks, client)
  • migrate(client) -> migrate(options, client)
  • makeAddJob(withPgClient) -> makeAddJob(options, withPgClient)
  • makeJobHelpers(job, { withPgClient }, baseLogger) -> makeJobHelpers(options, job, { withPgClient, logger? })
  • makeNewWorker(tasks, withPgClient, options, continuous) -> makeNewWorker(options, tasks, withPgClient, continuous)

Also if you're a TypeScript user: we've renamed WorkerSharedOptions to SharedOptions and added a new WorkerSharedOptions. This is particularly relevant if you're using the WorkerUtils class. We've also tweaked what options are available on each of these, but this is unlikely to affect you negatively.

v0.4.0

Performance improvements and ability to efficiently queue jobs from JS.

BREAKING CHANGES:

  • TypeScript:
    • the ID of a job is a string (database bigint), we previously incorrectly stated it was a number.
    • Helpers was renamed to JobHelpers
    • TaskOptions was renamed to TaskSpec
  • queue_name is now nullable (leave it null for maximum parallel performance)
  • when a job is modified using a job_key, the queue_name attribute is now reset like the other attributes

WARNINGS:

  • The database schema has changed; your code should not depend on the database schema, only on the public interfaces (add_job, remove_job, etc), so this shouldn't be an issue.

New features:

  • Significantly enhanced performance
    • Changes database schema such that a job_queue record is only added/checked when necessary
    • Uses prepared statements
    • Can override the PostgreSQL pool size on the CLI (via --max-pool-size)
  • Dedicated API for queueing jobs from JavaScript/TypeScript (makeWorkerUtils / quickAddJob; @mrmurphy, @benjie #60)
  • --once now respects --jobs, so it can run jobs in parallel
  • jobKey is now available via TypeScript API (@tim-field, #78)

Other:

  • Overhauled the perfTest script
  • Upgraded dependencies

v0.3.0-rc.0

v0.3.0-rc.0 was never released as v0.3.0 because we jumped to v0.4.0 too soon.

New features:

  • job_key enables existing jobs to be updated and deleted; can also be used for de-duplication (@gregplaysguitar, @benjie #63)

Fixes:

  • Fixes runner.stop() (@MarkCBall, #66)

v0.2.0

BREAKING CHANGES:

  • The debug task helper has been replaced with a logger helper which is a Logger instance (see README)
  • The -1 shortcut for "run once" never worked; it has been removed
  • Unrecognised command-line arguments will now cause an error to be thrown

New features:

  • Added --schema-only CLI flag for installing/updating the schema (running migrations) only
  • It's now possible to override how logs are output by supplying a logFactory (see README)
  • query helper reduces boilerplate

Fixes:

  • We never needed uuid-ossp so we've removed the requirement (you may want to remove the extension from your DB manually)

v0.1.0

  • Add database 'error' handler to avoid crashes (@madflow #26)
  • DATABASE_URL can now be used in place of connectionString (@madflow, @benjie #20 #27)
  • Improve documentation (@madflow, @archlemon, @benjie #11 #18 #31 #33)
  • Improve testing (@madflow #19 #30)
