Concourse Versions Save

✈️ Features

• Optimize build log collection (#7334 ) @evanchaoli _^:link:
  • Optimized a SQL statement used to remove build logs. This optimization will specially benefit large deployments that have a lot of pipelines.

🐞 Bug Fixes

• Prevent open redirect to other hosts (#7460) @taylorsilva _^:link:

• Fix github-release-resource with graphql update (https://github.com/concourse/github-release-resource/pull/107) @kirillbilchenko _^:link:

🤷 Miscellaneous

• Backport baggageclaim v1.8.0 to release/6.7.x (#7428) @taylorsilva _^:link:

• Use overlay driver for worker integration test [6.7.x] (#7435) @aoldershaw _^:link:

📦 Bundled resource types

✈️ Features

• Fly clear-resource-cache command (#7003) @EstebanFS _^:link:

  • Added fly command clear-resource-cache, you could use this following the next format fly -t ci clear-resource-cache -r pipeline/resource [--version some:version]

• Build page shows name of who triggered the build in header line of build page (#7112) @evanchaoli _^:link:

  • The build page now shows the username of who triggers the build if the build is triggered manually.

• Add page to view all builds/resource versions downstream/upstream from a root resource version (#7125) @chenbh _^:link:

  • Disabled by default since computing causality for large datasets can be expensive, use --enable-resource-causality or $CONCOURSE_ENABLE_RESOURCE_CAUSALITY=true to enable the web UI and API endpoint.
    • Most datasets (like the merge commit for this PR) have < 100 builds and/or resource versions and take < 100ms, but it's possible for some "slow paced" resource versions (i.e. very infrequent new versions) to generate extremely large datasets
    • There is an automatic cutoff at 5000 builds or 25000 resource versions. On our deployment, the call for our slowest paced resource took about ~7 seconds to process, most of which is spent in the DB query
  • The causality page can be navigated to from the resource page
  • The causality page displays all the builds and resource versions that was generated from (downstream) or resulted in (upstream) the creation of a particular resource version
  • The downstream graph will put the root resource version on the left whereas the upstream graph will put it on the right
  • It takes into account all the intermediate resource versions when computing the final graph. In the picture above, while the resource page only shows that git version: 123 is a direct input to integrate #4 & #5, there is also an indirect link from git version: 123 -> test #19 -> ... -> intermediate-3 version:123 -> integrate #6 & #6.1

• Support soft policy enforcement (#7139) @evanchaoli _^:link:

  • This feature doesn't break the existing OPA policy check. If you have enabled OPA policy check, and you don't need "soft" policy enforcement, then you just don't need to do any configuration change.
  • 3 new ATC cli options are added:
    • CONCOURSE_OPA_RESULT_ALLOWED_KEY: specifies a key of allow flag in OPA returned result
    • CONCOURSE_OPA_RESULT_SHOULD_BLOCK_KEY: specifies a key of should-block flag in OPA returned result
    • CONCOURSE_OPA_RESULT_MESSAGES_KEY: specifies a key of messages in OPA returned result

  For example, if OPA returns the following result:

  {
      "result": {
          "allow": true,
          "block": true,
          "reasons": ["foo", "bar"]
      }
  }
  

  then CONCOURSE_OPA_RESULT_ALLOWED_KEY should be set to result.allow; CONCOURSE_OPA_RESULT_SHOULD_BLOCK_KEY should be result.block, and CONCOURSE_OPA_RESULT_MESSAGES_KEY should be result.reasons.

  NOTE: allow and block in OPA result should be boolean type, because it's easy to convert other types to boolean in an OPA policy.

• Add ability to comment on a build (#7147) @multimac _^:link:

  • You can now leave comments on builds. For instance, this can be used to give context to your coworkers about why a particular build failed:

  • If a build has a comment, it is displayed with a small marker to help you quickly find builds of interest. Hovering over the build displays a portion of the comment:

• Add teamName to concourse_steps_wait_duration metrics (#7154) @Esysc _^:link:

• Use browser cache API for dashboard caching (#7247) @aoldershaw _^:link:

  • The cached API responses on the dashboard no longer need to get truncated, which was previously introduced to work around localStorage limits

• Allow interpolation in the across step values (#7252) @aoldershaw _^:link:

  • The across step now supports dynamic interpolation of values. For instance, this can be combined with the set_pipeline step and instanced pipelines to set a dynamic list of pipelines:

    - load_var: branches
      file: branches/branches.json
    - across:
      - var: branch
        values: ((.:branches))
      set_pipeline: my-app
      file: ci/pipelines/my-app.yml
      instance_vars: {branch: ((.:branch))}
    

• Cache the list of workers in memory (#7268) @aoldershaw _^:link:

  • Scheduling containers should be more performant by reducing the number of required database calls

• Optimize build log collector (#7327) @evanchaoli _^:link:

  • Optimized a SQL statement used to remove build logs. This optimization will specially benefit large deployments that have a lot of pipelines.

• Enable emitting dogstatsd metrics over uds (#7338) @jmhwang7 _^:link:

  • The Datadog emitter can now be configured to communicate with the Datadog agent over Unix Domain Sockets

• containerd: Mount /dev/fuse to privileged containers (#7098) @aoldershaw _^:link:

• atc(fix): fixed a bug in resource check rate limiter. (#7102) @evanchaoli _^:link:

• fix BaseResourceType for streamed volumes (#7108) @vito _^:link:

• Fix worker restart issue with containerd daemon and beacon (#7113) @muntac _^:link:

  • Fix worker stall issue when restarting with containerd. Exit the worker's beacon process gracefully if any other top level process like the containerd daemon fails. Wait for containerd daemon to come up before starting the containerd Garden server.

• Fix memory leak in notification bus (#7120) @aoldershaw _^:link:

• containerd: default to root if /etc/passwd is missing (#7124) @aoldershaw _^:link:

  • Fixes a regression introduced in 7.3.0 that prevented containers that don't have an /etc/passwd file from running

• Fix algorithm considering reruns as new builds (#7144) @taylorsilva _^:link:

  • Fixes pipelines getting stuck with the same inputs when a job upstream of a job with version: every succeeds and is rerun

• containerd: keep tasks running after concourse worker restarts gracefully (#7148) @aoldershaw _^:link:

  • The containerd runtime is now more resilient to the concourse worker process gracefully restarting (e.g. via monit restart)
    • Tasks that were started prior to restart will continue to run when the worker process comes back up
    • This matches the behaviour of the Guardian runtime

• Fixed build log reaper not respecting when both Days and Builds are set (#7179) @EstebanFS _^:link:

  • The build log reaper has two options for determining when to reap logs. Before, if both of the options are set, it would reap if either of the two options were true, rather than requiring both of them to be satisfied

• Apply a minimum rate limit for resource checking (#7218) @aoldershaw _^:link:

  • If CONCOURSE_MAX_CHECKS_PER_SECOND is unset, Concourse will try to distribute checks evenly over the course of the check interval to reduce the concurrent load on external systems.
  • If there are few resources in a Concourse deployment (~1-20), checks may have to wait a substantial amount of time to run in order to space the checks out evenly. However, there's no real benefit to doing this, since having just a few resources doesn't cause significant load in the first place.
  • Now, Concourse ensures that at least one check is allowed to run per second

• atc/db: prevent creation of duplicate check builds (#7221) @taylorsilva _^:link:

  • Prevent duplicate checks from being created for a single resource

• Fix browser back button after selecting a group (#7249) @aoldershaw _^:link:

  • Previously, if a pipeline group was selected in the UI, the back button would not work (you'd have to press it twice to go back)

• set_pipeline unpauses previously archived pipelines (#7255) @aoldershaw _^:link:

  • When an archived pipeline is un-archived via the set_pipeline step, it will be unpaused

• GC task caches belonging to archived pipelines (#7272) @aoldershaw _^:link:

• containerd: Clean up networking files in /tmp (#7276) @taylorsilva _^:link:

  • Fixed a bug where the containerd runtime would create networking related files under /tmp and never delete them. They are now made under the --work-dir set for the worker and are cleaned up when the container is deleted. You can delete any lingering network files under your workers /tmp directory after upgrading.

• Fix prometheus emitter not setting default attributes (#7294) @chenbh _^:link:
  Additional metrics attributes configured by --metrics-attribute now propagates to the prometheus emitter correctly.

• run check builds GC in batch (#7323) @xtremerui _^:link:

📦 Bundled resource types

🚨 Breaking

• Bump opentelemetry to 0.19.0 (#6787) @aoldershaw _^:link:
  • The service name Honeycomb tracing exporter is now configured via the more general --tracing-service-name (CONCOURSE_TRACING_SERVICE_NAME) rather than --tracing-honeycomb-service-name (CONCOURSE_TRACING_HONEYCOMB_SERVICE_NAME)

✈️ Features

• Cache streamed volumes and use local cache when looking for volumes (#6660) @evanchaoli _^:link:
  Optimize resource cache streaming and get step.

  • Mark streamed resource cache volumes as resource cache, to avoid duplicate streaming in next runs.
  • If a resource from a get can be found on some workers, then get step will do nothing. This will reduce times of Concourse connecting to external systems, such as git, docker hub, and so on.
  • This feature is currently opt-in and can be enabled using CONCOURSE_ENABLE_CACHE_STREAMED_VOLUMES flag.

• Re-ordering instanced pipelines (#6830) @EstebanFS _^:link:

  • Instanced Pipelines are allowed to be re-ordered with in their group through the UI (using the drag and drop functionality) or using the fly command: fly -t dev oip -g groupName -p key1:var1 -p key2:var2

• Enhance syslog-drainer to make it more useful (#6834) @SimonXming _^:link:

  • Add event_id into syslog-drainer entries, to get the correct order of "drained" build logs.
  • Add more supported event_type for syslog-drainer to include more info for "drained" build logs.

• Enhance webhook triggered checks (#6854) @evanchaoli _^:link:

  • When multiple pipelines hold a common resource and webhook calls against the common resource, checks are sent to all pipelines at same time. Without this enhancement, each webhook call will cause a check to run. With this enhancement, only a single check will run, which is the expected behavior as a global resource.

• Allow override of container limits in task config (#6867) @BooleanCat _^:link:

  • Pipeline authors can now set container_limits for reusable tasks in pipelines. Any limits set in the pipeline will override the limits set within the reusable task file.

• Use cursor-based pagination for build events (#6873) @aoldershaw _^:link:

  • Optimizes fetching build logs from the DB for builds with massive logs

• Use display_user_id field to render username in web interface (#6970) @logyball _^:link:

• Set Content-Security-Policy and Cache-Control Headers (#6949) @taylorsilva _^:link:

  • A Content-Security-Policy header is now set with a default value that will block framing of the Concourse web UI. This was already possible with the default value of the X-Frames-Option header.
    • The CSP header value is configurable with CONCOURSE_CONTENT_SECURITY_POLICY
  • A Cache-Control header is set on every page with a default value of no-store, private. The value of the header is overwritten for some paths (i.e. web assets)

• Fix volume GC query to not include volumes with children (#6902) @xtremerui _^:link:

  • Fix query that causes volume cannot be destroyed as children are present in web and update or delete on table "volumes" violates foreign key constraint "volumes_parent_id_fkey" in DB.

• Set autocomplete to off for login form (#6920) @taylorsilva _^:link:

  • add autocomplete="off" to the top-level form and username tags.

• Ignore "not found" error on process deletion for Containerd runtime (#6959) @aoldershaw _^:link:

• worker: Set PATH based on UID instead of container's privileged state (#6982) @taylorsilva _^:link:

  • Containerd: fixed a bug where PATH did not contain directories to system tools (i.e. /sbin) when a user/process was root. Only effects unprivileged containers.

• Fix Postgres deadlock when frequently setting pipelines (#7011) @aoldershaw _^:link:

• containerd: allow use of non-existent uids (#7029) @muntac _^:link:

📦 Bundled resource types

🚨 Breaking

• Wait for worker matching strategy when scheduling build steps (#6635) @multimac _^:link:
  • Previously, if no workers satisfied the container placement strategy for a step (with the exception of task steps when using the limit-active-tasks placement strategy), the step would simply error the build
  • Now, all steps will wait for a worker to become available
  • The metric concourse_tasks_waiting was removed and replaced with concourse_steps_waiting{type="task"}

✈️ Features

• Add ability to navigate to resources page from build page (#6662) @chenbh _^:link:
  UI: clicking on the version text for a get/put step in the Build page will now navigate directly to the Resource page with the corresponding version expanded

• Allow using LDAP as a password connector (#6671) @aoldershaw _^:link:

  • By setting --password-connector ($CONCOURSE_PASSWORD_CONNECTOR) to ldap, you can authenticate to Concourse with fly login -u ... -p ... using your LDAP credentials
    • Enabling this feature prohibits the use of local users
  • If you use an attribute other than username for authenticating with LDAP (e.g. email address), you can now configure --username-prompt ($CONCOURSE_USERNAME_PROMPT) to change the help text when logging in via the UI

  • Now, the Containerd matches Guardian's behavior by:
    • Detecting the external IP of the host (can be set explicitly using CONCOURSE_CONTAINERD_EXTERNAL_IP)
    • Extracting the MTU from the network interface corresponding with that IP (can be set explicitly using CONCOURSE_CONTAINERD_MTU)

📦 Bundled resource types

🚨 Breaking

• Run checks as builds (#6022) @vito _^:link:

  • Breaking change: unique_version_history can no longer be configured on resource types. No one seemed to be using it, and it made internal architecture unnecessarily complicated. The need for it should go away entirely as we make progress on the v10 roadmap.
  • Resource check operations, which collect and save versions for pipeline resources, are now run as builds.
    • This is largely an internal architecture refactor, but it also improves UX - check output can now be viewed on the resource page!
  • fly check-resource and fly check-resource-type now stream the checking output to the user, just like fly watch and fly trigger-job.
  • This change includes a migration to convert id column of the builds table and all tables referencing build_id to a bigint. This is unfortunately a slow migration, so please anticipate downtime proportional to the amount of builds in your database.
    • If the migration fails with deadlock detected, shut down the other web nodes first.
    • Our large-ish scale test environment took about an hour.

• Remove aggregate step (#6349) @taylorsilva _^:link:

  • Removing the aggregate step as planned. It is succeeded by the in_parallel step.

✈️ Features

• The formerly-experimental containerd runtime is now GA and is considered ready for production use _^:link:

  • We will be changing the default container runtime from Guardian to containerd in coming releases, but we encourage using the containerd runtime ASAP
  • To enable the containerd runtime, set --runtime ($CONCOURSE_RUNTIME) to containerd on the concourse worker command
  • You will also need to convert any --garden-* ($CONCOURSE_GARDEN_*) flags to their containerd counterparts:
    • --garden-request-timeout ($CONCOURSE_GARDEN_REQUEST_TIMEOUT) -> --containerd-request-timeout ($CONCOURSE_CONTAINERD_REQUEST_TIMEOUT)
    • --garden-dns-proxy-enable ($CONCOURSE_GARDEN_DNS_PROXY_ENABLE) -> --containerd-dns-proxy-enable ($CONCOURSE_CONTAINERD_DNS_PROXY_ENABLE)
    • --garden-network-pool ($CONCOURSE_GARDEN_NETWORK_POOL) -> --containerd-network-pool ($CONCOURSE_CONTAINERD_NETWORK_POOL)
    • --garden-max-containers ($CONCOURSE_GARDEN_MAX_CONTAINERS) -> --containerd-max-containers ($CONCOURSE_CONTAINERD_MAX_CONTAINERS)
    • $CONCOURSE_GARDEN_DENY_NETWORKS -> --containerd-restricted-network ($CONCOURSE_CONTAINERD_RESTRICTED_NETWORK)
    • $CONCOURSE_GARDEN_DNS_SERVER -> --containerd-dns-server ($CONCOURSE_CONTAINERD_DNS_SERVER)
  • If you rely on any Garden config that is not yet supported on our containerd runtime, please open an issue

• Perform image fetching using check/get sub-steps (#6153) @vito _^:link:

  • Image fetching for resources and resource types is now handled explicitly in the build plan using check and get steps, and can be inspected in the UI

  

• Show resource check build output in web UI (#6137) @vito _^:link:

• Enforce SetPipeline policy check in set_pipeline step (#5932) @cludden _^:link:

  • When OPA integration is enabled, the set_pipeline step now respects the same policy check as fly set-pipeline

• Speed up database queries by adding a job_id column to build image resource caches table and adding an index for ordering builds of a job (#5993) @clarafu _^:link:

• Allow globs in groups (#6060) @andy-paine _^:link:

  • groups in a pipeline can now match jobs based on globs e.g.:

    groups:
    - name: deploy
      jobs:
      - deploy-*
    

• Add flag to concourse worker to overwrite init binary path for the containerd runtime (#6086) @chenbh _^:link:

  • The init binary can be configured using the --containerd-init-bin flag ($CONCOURSE_CONTAINERD_INIT_BIN)

• Make CNI plugins directory configurable for the containerd runtime (#6120) @muntac _^:link:

  • CNI plugins directory can be configured using the --containerd-cni-plugins-dir flag ($CONCOURSE_CONTAINERD_CNI_PLUGINS_DIR)

• Fallback fly intercept to sh when bash is missing (#6098) @shua _^:link:

  • If no command is specified,fly intercept will first try to use bash for an interactive shell, but if the container returns an error indicating bash is not available, fly will fallback to the more common (but more limited) sh
  • If this fallback logic is not desired, the user can explicitly specify bash as the path argument to the fly intercept command

• Add Honeycomb.io as optional tracing backend (#6103) @spire-allyjweir _^:link:

• [experimental] Group instanced pipelines on UI (#6105) @aoldershaw _^:link:

  • Instanced pipelines (RFC) provide a mechanism for constructing multiple instances of a pipeline template that differ by some parameters
    • e.g. to support multiple release lines, you may have a collection of instanced pipelines called release that differ by the version line (1.0.x, 1.1.x, 2.0.x, etc.)
  • All instanced pipelines with the same name (but different parameters) will be collected in the UI into a grouping of related pipelines, removing clutter from the dashboard when there are many instances of a pipeline template
  • Instanced pipelines are currently experimental until we work out the UX, but if you'd like to play around with them, you can set the flag --enable-pipeline-instances ($CONCOURSE_ENABLE_PIPELINE_INSTANCES)

• Update go module dependencies [go.opentelemetry.io/otel] (#6106) @christophermancini _^:link:

• Implement support for Vault KV v2 backends (#6115) @daviddob _^:link:

• add support for exporting traces via OTLP (#6122) @christophermancini _^:link:

  • Added support for OTLP as a target for traces to be exported to

• Add index to speed up build deletion, fix up a few issues with checks as builds (#6125) @vito _^:link:

• Add --team flag to fly order-pipelines command (#6132) @witjem _^:link:

• Add --team option to fly get-pipeline command (#6144) @techgaun _^:link:

• Add --team option to fly expose-pipeline command (#6169) @techgaun _^:link:

• Ensure pipelines contain at least one job (#6159) @taylorsilva _^:link:

  • Pipelines are now validated to ensure that they contain at least one job - pipeline configs with no jobs will be rejected

• set_pipeline step prints 'no changes to apply' (#6164) @mdb _^:link:

  • set_pipeline now prints "no changes to apply" and thereby behaves similarly to fly set-pipeline when a pipeline config contains no changes.

• Update colours and contrast (#6168) @jomsie _^:link:

• Experimental support for P2P Volume Streaming (#6186) @evanchaoli _^:link:

  • Support P2P volume streaming directly between two workers instead of through the ATC.
    • This is an opt-in feature enabled with --enable-p2p-volume-streaming or env var $CONCOURSE_ENABLE_P2P_VOLUME_STREAMING on the web nodes. When this feature is enabled, --baggageclaim-bind-ip on workers should be set to 0.0.0.0 so that baggage claim can be accessed from another workers.
    • This should only be used for clusters where all workers can reach each other on the same local network.
    • Adds --baggageclaim-p2p-interface-name-pattern and --baggageclaim-p2p-interface-family to the worker command.

• Add a new metric "volumes streamed" (#6187) @evanchaoli _^:link:

• Log the worker name when creating a container fails (#6188) @evanchaoli _^:link:

• Support chained container placement strategies. (#6208) @evanchaoli _^:link:

  • Enhanced container placement strategy to support chained strategies, for example CONCOURSE_CONTAINER_PLACEMENT_STRATEGY=volume-locality,fewest-build-containers

• Add new container placement strategies: limit-max-containers and limit-max-volumes (#6339) @evanchaoli _^:link:

  • These strategies prevent scheduling on workers that already have too many containers or volumes on them (respectively), according to a limit set by --max-active-containers-per-worker, --max-active-volumes-per-worker
  • A possibly placement strategy chain to better balance workloads across workers could be [limit-max-containers, limit-max-volumes, volume-locality, fewest-build-containers]
    • This strategy chain first filters out workers that already have too many containers/volumes, then chooses all the workers with the most inputs already present locally, breaking ties by preferring the worker with fewer containers
  • Note: workers are not guaranteed to never exceed the maximum specified limits

• go-concourse surfaces error messages on saving pipelines (#6222) @andy-paine _^:link:

  • where fly set-pipeline would simply print forbidden when the underlying API call returned a 403 status, now the body of the response will be printed. In particular, errors originating from OPA policy check rejections will be printed.

• Don't enforce timeouts during image fetching (#6237) @vito _^:link:

• Ignore paused jobs when displaying pipeline status in the UI (#6270) @chenbh _^:link:

  • The UI will no longer consider paused jobs when figuring out the overall status of a pipeline

• Skip checking put-only resources (#6281) @evanchaoli _^:link:

  • An optimization which should lower the resource checking load on some instances: instead of checking all resources, only resources which are actually used as inputs will be checked. This feature was released in 6.0.0 and reverted in 6.6.0 because of its side effects. Now after resolving those side effects, it's back.
  • The --enable-skip-checking-not-in-use-resources flag has been removed as it is no longer needed.

• fly set-pipeline prints pipeline name and instance vars (#6300) @aoldershaw _^:link:

• Remove legacy logic for dealing with resource versions that have a check order of zero (#6323) @clarafu _^:link:

  • Includes a migration that will delete any versions with a check order of 0. This should not affect anything because versions with a check order of 0 are invalid versions.
  • Should speed up some queries that had legacy logic with filtering on versions with a check order of 0.

• fly: Add fish auto complete (#6329) @Sasasu _^:link:

  • fly: add autocomplete for fish.

• start containerd with low oom_score (#6330) @muntac _^:link:

  • It is recommended that containerd be started with an oom_score of -999. We want it to be at the level of other system daemons. This is so that containerd never runs into an out of memory state before the containers it's managing are cleaned up. At the same time it should not be unkillable.

• Give worker registration its own database connection pool (#6332) @taylorsilva _^:link:

  • Give the worker registration endpoint its own database connection pool to avoid the situation where the API connection pool is maxed out and workers fail to register and stall

• Allow underscore in identifiers (#6338) @aoldershaw _^:link:

• Support for mTLS (#6355) @nickhyoti _^:link:

  • Added support for mTLS between Concourse and a reverse proxy that may be in front of Concourse

• Allow configuring login and query timeouts for Vault (#6362) @evanchaoli _^:link:

  • These timeouts can be configured using CONCOURSE_VAULT_LOGIN_TIMEOUT and CONCOURSE_VAULT_QUERY_TIMEOUT respectively
  • The new default login timeout is 60s

• Expose username of who manually triggered build to build metadata. (#6369) @evanchaoli _^:link:

  • fly builds has a new column created by that shows a user ID if a build is triggered manually.

  • A new build metadata BUILD_CREATED_BY may be exposed to resource. It is not exposed by default; you need to turn it by add expose_build_created_by when defining a resource:

    resources:
    - name: some-resource
      type: some-type
      expose_build_created_by: true
      source:
        ...
    

  • As different authentication connectors populate different claims, a new concourse web CLI option --concourse-display-user-id-per-connector is added that allow cluster administrator to configure which claims field should be consider as unique user id

    • Values of this option should be in format <connector>:<fieldname>
      • connector is one of: ldap, github, cf, bitbucket-cloud, gitlab, microsoft, oauth, oidc or saml
      • fieldname is one of:
        • user_id mapping to claims' user id field
        • name mapping to claims' username field
        • username mapping to claims' preferred username field
        • email mapping to claims' email field

• Allow disabling resource checking for individual resources (#6386) @taylorsilva _^:link:

  • Automatic resource checking for individual resources can be disabled by setting check_every: never in a resource's definition

• db: lidar checks put-only resources with failed checks (#6412) @taylorsilva _^:link:

  • Lidar now checks any put-only resources that ran a check which failed.

• Add a flag to migrate to the latest db version (#6426) @taylorsilva _^:link:

  • add a --migrate-to-latest-version flag to the migrate command. This flag has concourse perform database migrations to the latest database version.
  • the concourse web command will still automatically migrate the database

• Enhance search bar filtering and allow filtering by instance group (#6433) @aoldershaw _^:link:

  • Allow filtering by exact match on the dashboard by quoting search terms
  • Allow applying multiple search filters simultaneously (e.g. team:"main" status:paused)
  • Make search suggestions more intelligent

• Add more tooltips for action buttons (#6453) @aoldershaw _^:link:

  • Many buttons in the UI now have a tooltip on hover to indicate what they do

• Bump BaggageClaim to v1.10.0 (#6500) @vito _^:link:

  • Windows workers will now shell out to the much faster robocopy executable for copying local files. This should dramatically improve performance for Windows tasks which utilize caches: for caching a bunch of tiny files.

• metrics: make tasks_wait_duration histogram record up to 1h (#6506) @marco-m-pix4d _^:link:

• Removes unnecessary indexes from build events tables (#6522) @clarafu _^:link:

• Allow @ in vars path (#6129) @xtremerui _^:link:

  • Allow "@" sign in a var's path e.g. ((var:"[email protected]".field))

🐞 Bug Fixes

• fly pin-resource requires a version if the resource is unpinned (#6095) @jamieklassen _^:link:

  • Previously, you could run the command on an unpinned resource without passing a version -- it would run and succeed, but do nothing. Now the command will fail and print an error message.

• Fix pipeline cards being rendered off-screen when sidebar was open (#6102) @aoldershaw _^:link:

  • Fixes occasional bug where pipelines would be rendered off-screen after a refresh on the dashboard

• Fix quoting for var subkeys (#6108) @vixus0 _^:link:

  • Fix interpolation of quoted variable fields containing special characters.

• Prevent set_pipeline runtime error (#6116) @mdb _^:link:

  • set_pipeline of a YML pipeline configuration file with no jobs: or resources: no longer causes a runtime error: invalid memory address or nil pointer dereference.

• Use default uid:gid if passwd file does not exist and username is "root" (#6142) @chenbh _^:link:

  • The containerd runtime will now default to uid:gid 0:0 if username is "root" but /etc/passwd file does not exist
  • This matches the behaviour of the default guardian backend

• Preserve whitespace within build output (#6157) @clarafu _^:link:

  • In v6.6.0, whitespace was collapsed in order to fix a bug with horizontal scrolling in the build output. This change will preserve all whitespace while also keeping the horizontal scrolling fix.

• Prevent retrying on worker error when build is aborted (#6197) @evanchaoli _^:link:

  • Fixed a endless build retry bug

• Limit configured by limit-active-tasks is not respected and more tasks can land on a worker (#6216) @aliculPix4D _^:link:

• Remove any existing guardian assets (#6257) @taylorsilva _^:link:

  • The worker will now clear out any existing Guardian assets on start-up (/var/gdn/assets)
  • This fixes in-place upgrade scenarios where guardian was using old versions of runc

• atc: abort a rerun build if input version gone (#6265) @xtremerui _^:link:

  • A rerun build will be aborted automatically if required version of any input is not available.

• set-pipeline prompted unpause-pipeline command should have --team option. (#6336) @evanchaoli _^:link:

  • Fixed a bug of fly set-pipeline where --team option was missing in the prompted unpause-pipeline command.

• Fix mount issues on containerd (#6348) @muntac _^:link:

  • Set the appropriate permissions for mounts in privileged containers.
  • Use the Linux default size for /dev/shm (shared memory) mount.

• Bump baggageclaim to 1.9.1 to fix deeply-nested volumes with overlay driver (#6393) @vito _^:link:

  • This was partially fixed by #5961, but that original fix did not solve the problem in all cases

• Ensure task, set_pipeline, load_var steps have names (#6410) @taylorsilva _^:link:

  • Return an error when no identifier is provided for task, set_pipeline, and load_var steps

• add lock for concourse migrate to latest version cmd (#6510) @xtremerui _^:link:

🤷 Miscellaneous

• Apply bigint migrations to build_events partitions and read from old/new columns instead (#6305) @vito _^:link:

  • Rather than migrating the build_events table's build_id column to bigint, which we found to be too slow in large deployments, this PR adds a new bigint column to the build_events table that is populated at runtime
  • When querying for build events, we consider both the old and new column, since builds run prior to the upgrade to 7.0.0 will only have the old column set

• Migrate build_id references to bigint (#6203) @vito _^:link:

  • This migration can be quite slow if you have a ton of builds, meaning web nodes may take a while to start upon upgrading.
  • This does not migrate the build_events table - that is handled in #6305
