Changelog

v0.45.0

Added

The query/cost check can now use Prometheus query stats to verify query evaluation time and the number of samples used by a query. See query/cost docs for details.

v0.44.2

Fixed

Fixed a crash in promql/series check when Prometheus instance becomes unavailable - #682.
Fixed false positive reports in alerts/template check - #681.

v0.44.1

Fixed

Rule names were not checked for correctly, allowing for rules with empty names to pass checks.
Fixed GitHub annotations being added to unmodified lines - #645.

v0.44.0

Added

Added exclude option to ci config block - #609.
Added minCount & severity to alerts/count check - #612. This allows to only show estimated alerts count only if there would be high enough (>= minCount) number of alerts. Setting severity as well allows to block rules that would create too many alerts.
GitHub reporter will now included folded list of all problems in the summary comment - #608.

Fixed

Fixed alerts/annotation check regexp matching - #613.
When running pint ci using GitHub integration annotation comments are now reported only on modified lines - #640.

v0.43.1

Fixed

Fixed --base-branch flag handling when branch name contains /.

v0.43.0

Added

Added --fail-on flag to pint lint command - #570.
Added tls section to prometheus configuration block - #540.

Changed

If a query run by pint fails because it was too expensive too run it will now be reported as a warning instead of an error.

Fixed

When validating queries using {__name__=~"...", foo="bar"} selectors pint could end up running queries matching a single label, like count({foo="bar"}), which could return too many results. This version ensures that queries always include name matcher to avoid that.

v0.42.2

Fixed

alerts/template check didn't correctly handle label_replace() calls in queries - #568.

v0.42.1

Fixed

Fixed --base-branch flag handling. Value of this flag wasn't being used correctly - #559.

v0.42.0

Fixed

Fixed incorrect results in promql/series check for time series with only a single data point.

v0.41.1

Fixed

Fixed parsing of alert for field values with long durations (for: 1d).

v0.41.0

Added

Added --fail-on flag to pint ci command - #525.

promql/rate will now look for queries that call rate() on results of sum(counter) via recording rules. Example:

- record: my:sum
  expr: sum(http_requests_total)

- alert: my alert
  expr: rate(my:sum[5m])

Added rule/for check.
Added owners configuration block for setting the list of allowed rule owner values. See configuration for details.

Changed

pint lint output will now include severity level as a text label - #524.

v0.40.1

Fixed

Fixed a bug in pint ci that would cause a failure if a directory was renamed.
Fixed false positive reports from promql/series check when a time series disappears from Prometheus.
Fixed Prometheus flags parsing in promql/range_query check.

v0.40.0

Added

Allow snoozing checks for entire file using # pint file/snooze ... comments.
Added lookbackRange and lookbackStep configuration option to the promql/series check - #493.

Changed

Reverted GitHub integration to use Pull Request Review API - #490.

v0.39.0

Changed

GitHub integration now uses Check Runs API - #478.

v0.38.1

Fixed

# pint file/disable comments didn't properly handle Prometheus tags, this is fixed now.

v0.38.0

Added

prometheus configuration blocks now accepts tags field with a list of tags. Tags can be used to disable or snooze specific checks on all Prometheus instances with that tag. See ignoring for details.

v0.37.0

Added

Added pint_rule_file_owner metric.

v0.36.0

Added

Added ability to expand environment variables in pint configuration file. See configuration for details.

v0.35.0

Added

Use uber-go/automaxprocs to automatically set GOMAXPROCS to match Linux container CPU quota.
Added labels/conflict check.
If you want to disable individual checks just for some time then you can now snooze them instead of disabling forever.

The difference between # pint disable ... and # pint snooze ... comments is that the snooze comment must include a timestamp. Selected check will be disabled until that timestamp. Timestamp must either use RFC3339 syntax or YYYY-MM-DD (if you don't care about time and want to snooze until given date). Examples:
```
# pint snooze 2023-01-12T10:00:00Z promql/series
# pint snooze 2023-01-12 promql/rate
- record: ...
  expr: ...
```

Changed

Removed cache option from prometheus config blocks. Query cache will now auto-size itself as needed.

If you have a config entry with cache option, example:
```
prometheus "prod" {
  uri   = "https://prometheus.example.com"
  cache = 20000
}
```
Then pint will fail to start. To fix this simply remove the cache option:
```
prometheus "prod" {
  uri = "https://prometheus.example.com"
}
```

v0.34.0

Added

Added rule/duplicate check.

v0.33.1

Fixed

Fixed a regression causing poor query cache hit rate.

v0.33.0

Added

Added uptime field in prometheus configuration block. This field can be used to set a custom metric used for Prometheus uptime checks and by default uses up metric. If you have a Prometheus with a large number of scrape targets there might be a huge number of up time series making those uptime checks slow to run. If your Prometheus is configured to scrape itself, then you most likely want to use one of metrics exported by Prometheus, like prometheus_build_info:
```
prometheus "prod" {
  uri    = "https://prometheus.example.com"
  uptime = "prometheus_build_info"
}
```

Changed

Refactored some queries used by promql/series check to avoid sending queries that might be very slow and/or return a huge amount of data.
Prometheus query cache now takes into account the size of cached response. This makes memory usage needed for query cache more predictable. As a result the cache option for prometheus config block now means the number of time series cached instead of the number of responses cached and the default for this option is now 50000.

v0.32.1

Fixed

promql/vector_matching was sending expensive queries resulting in high memory usage, this is now fixed.

v0.32.0

Added

Added pint_prometheus_cache_evictions_total metric tracking the number of times cache results were evicted from query cache.
Allow disabling individual checks for the entire file using # pint file/disable ... comments.

Changed

Refactored query cache to only store queries that are requested more than once. This will avoid storing big responses that are never requested from the cache.

Fixed

Config validation will now check for duplicated prometheus block names.

v0.31.1

Fixed

Fixed performance regression slowing down pint watch over time.

v0.31.0

Added

prometheus configuration block now accepts optional headers field, for setting request headers that will be attached to any request made to given Prometheus server. Example:
```
prometheus "protected" {
uri      = "https://prod.example.com"
headers  = {
  "X-Auth": "secret",
  "X-User": "bob"
}
```

Changed

Prometheus range query handling was rewritten to improve memory usage caused by queries returning huge number of results. As a result pint should use up to 5x less memory.

Fixed

Fixed false positive reports in promql/vector_matching for rules using on(...). Example:
```
sum(foo) without(instance) * on(app_name) group_left() bar
```
Don't log passwords when Prometheus URI is using basic authentication.
Fixed false positive reports in alerts/template suggesting to use humanize on queries that already use round().
Fixed false positive reports in alerts/comparison when bool modifier is used on a condition that is guarded by another condition. Example:
```
alert: Foo
expr: (foo > 1) > bool 1
```
Fixed false positive reports in alerts/template warning about labels removed in a query despite being re-added by a join.

v0.30.2

Fixed

Fixed incorrect line number reporting on BitBucket annotations.

v0.30.1

Fixed

Fixed handling of symlinks when running pint lint and pint watch commands.

v0.30.0

Added

BitBucket only allows for annotations on modified lines, so when a high severity problem is reported on unmodified line pint will move that annotation to the first modified line, so it's still visible in BitBucket. Now pint will also add a note to that annotation to make it clear that the problem is really on a different line.
alerts/template will now run extra checks to validate syntax of queries executed from within alerting rule templates.

Example template using sum(xxx query that's missing closing ):

{% raw %}
```
- alert: ...
  expr: ...
  annotations:
    summary: |
      {{ with query "sum(xxx" }}
      {{ . | first | value | humanize }}
      {{ end }}
```
{% endraw %}
If a file is ignored pint will now note that using Information level annotation. This will make it more obvious that a CI check passed because pint didn't run any checks due to file being excluded.

Changed

Prometheus rule files can be symlinked between directories. If the symlink source and target files are in a different directory they can end up querying different Prometheus server when running ping checks. This means that when modifying symlink target file checks must be executed against both symlink source and target. Until now pint was ignoring symlinks but starting with this release it will try to follow them. This means that if you modify a file that has symlinks pointing to them pint will try run checks against those symlinks too.

NOTE: pint can only detect and check symlinks if they are located in the current working directory (as seen by running pint process) or its sub-directories.

Fixed

Fixed a regression in promql/vector_matching that would cause a panic when parsing function calls with optional arguments.

v0.29.4

Fixed

promql/vector_matching was incorrectly handling queries containing function calls with multiple arguments.

v0.29.3

Fixed

Revert 'Use smaller buffers when decoding Prometheus API responses' change.

v0.29.2

Fixed

Use smaller buffers when decoding Prometheus API responses.

v0.29.1

Fixed

Fixed wrong request formatting for Prometheus metric metadata queries.

v0.29.0

Changed

Switched from using prometheus/client_golang API client to streaming JSON library prymitive/current

Fixed

Avoid reporting same issue multiple times in promql/rate and promql/regexp checks.

v0.28.7

Changed

Updated Prometheus modules to v2.38.0. This adds support for toTime template function.

v0.28.6

Fixed

Fixed symlink handling when running pint lint.

v0.28.5

Fixed

Remove noisy debug logs.

v0.28.4

Added

Added pint_prometheus_cache_miss_total metric.

Changed

Reduce log level for File parsed messages.

Fixed

Purge expired cache entries faster to reduce memory usage.

v0.28.3

Fixed

Fix absent() handling in alerts/comparison #330.

v0.28.2

Added

Added --min-severity flag to the pint lint command. Default value is set to warning.

Fixed

Fix a regression in promql/vector_matching introduced in previous release.
Fix promql/series disable comments not working when there are multiple comments on a rule.
promql/series no longer emits an information message metric is generated by alerts ....

v0.28.1

Fixed

Don't use topk in promql/vector_matching check to avoid false positives.

v0.28.0

Added

promql/rate check will now also validate deriv function usage.
alerts/annotation check will now recommend using one of humanize functions if alert query is returning results based on rate() and the value is used in annotations.

Changed

promql/series check now supports more flexible # pint disable promql/series(...) comments. Adding a comment # pint disable promql/series({cluster="dev"}) will disable this check for any metric selector with cluster="dev" matcher.
query/cost check will now calculate how much Prometheus memory will be needed for storing results of given query. bytesPerSample option that was previously used to calculate this was removed.
prometheus {} config block now allows to pass a list of paths to explicitly ignore by setting exclude option. Existing paths option was renamed to include for consistency. Example migration:
```
prometheus "foo" {
  [...]
  paths = [ "rules/.*" ]
}
```
becomes
```
prometheus "foo" {
  [...]
  include = [ "rules/.*" ]
}
```

Fixed

pint_last_run_checks and pint_last_run_checks_done were not updated properly.

v0.27.0

Added

Deduplicate reports where possible to avoid showing same issue twice.
rule/link check for validating URIs found in alerting rule annotations.

Changed

Add more details to BitBucket CI reports.
More compact console output when running pint lint.

v0.26.0

Added

promql/range_query check.

Fixed

Strict parsing mode shouldn't fail on template errors, those will be later reported by alerts/template check.

v0.25.0

Changed

All timeout options are now optional. This includes following config blocks:
- prometheus { timeout = ... }
- repository { bitbucket { timeout = ... } }
- repository { github { timeout = ... } }
pint will now try to discover all repository settings from environment variables when run as part of GitHub Actions workflow and so it doesn't need any repository { github { ... } } configuration block for that anymore. Setting GITHUB_AUTH_TOKEN is the only requirement for GitHub Actions now.

v0.24.1

Fixed

Fixed line reporting on some strict parser errors.

Added

Added --base-branch flag to pint ci command.

v0.24.0

Added

Added rate limit for Prometheus API requests with a default value of 100 requests per second. To customise it set rateLimit field inside selected prometheus server definition.
Added pint_last_run_checks and pint_last_run_checks_done metrics to track progress when running pint watch.

v0.23.0

Fixed

Improved range query cache efficiency.

Added

Added extra global configuration for promql/series check. See check documentation for details.
prometheus server definition in pint config file can now accept optional cache field (defaults to 10000) to allow fine tuning of built-in Prometheus API query caching.
Added pint_prometheus_cache_size metric that exposes the number of entries currently in the query cache.

v0.22.2

Fixed

Improved error reporting when strict mode is enabled.

v0.22.1

Fixed

Fixed high memory usage when running range queries against Prometheus servers.

v0.22.0

Changed

The way pint sends API requests to Prometheus was changed to improve performance.

First change is that each prometheus server definition in pint config file can now accept optional concurrency field (defaults to 16) that sets a limit on how many concurrent requests can that server receive. There is a new metric that tracks how many queries are currently being run for each Prometheus server - pint_prometheus_queries_running.

Second change is that range queries will now be split into smaller queries, so if pint needs to run a range query on one week of metrics, then it will break this down into multiple queries each for a two hour slot, and then merge all the results. Previously it would try to run a single query for a whole week and if that failed it would reduce time range until a query would succeed.

Fixed

Strict parsing mode didn't fully validate rule group files, this is now fixed and pint runs the same set of checks as Prometheus.
Fixed promql/series handling of rules with {__name__=~"foo|bar"} queries.
If Prometheus was stopped or restarted promql/series would occasionally report metrics as "sometimes present". This check will now try to find time ranges with no metrics in Prometheus and ignore these when checking if metrics are present.

v0.21.1

Fixed

pint_prometheus_queries_total and pint_prometheus_cache_hits_total metric wasn't always correctly updated.
Ignore unknown metric types in promql/rate.

v0.21.0

Added

promql/rate check will now report if rate() or irate() function is being passed a non-counter metric.

v0.20.0

Fixed

pint will now correctly handle YAML anchors.

v0.19.0

Added

Parsing files in relaxed mode will now try to find rules inside multi-line strings #252. This allows direct linting of k8s manifests like the one below:

---
kind: ConfigMap
apiVersion: v1
metadata:
  name: example-app-alerts
  labels:
  app: example-app
data:
  alerts: |
    groups:
      - name: example-app-alerts
        rules:
          - alert: Example_Is_Down
            expr: kube_deployment_status_replicas_available{namespace="example-app"} < 1
            for: 5m
            labels:
              priority: "2"
              environment: production
            annotations:
              summary: "No replicas for Example have been running for 5 minutes"

v0.18.1

Fixed

Fixed incorrect line reported when pint fails to unmarshal YAML file.

v0.18.0

Added

Allow fine tuning promql/series check with extra control comments # pint rule/set promql/series min-age ... and # pint rule/set promql/series ignore/label-value ... See promql/series for details.
promql/regexp will report redundant use of regex anchors.

Changed

promql/series will now report missing metrics only if they were last seen over 2 hours ago by default. This can be customised per rule with comments.

v0.17.7

Fixed

Fix problem line reporting for rule/owner check.
Add missing rule/owner documentation page.

v0.17.6

Fixed

Fixed false positive reports from promql/series check when running pint watch.

v0.17.5

Added

Added pint_last_run_duration_seconds metric.
Added --require-owner flag support to pint ci command.

Fixed

Better handling of YAML unmarshal errors.

v0.17.4

Fixed

Fixed false positive reports from alerts/template check when absent() is used inside a binary expression.

v0.17.3

Fixed

File parse errors didn't report correct line numbers when running pint ci.

v0.17.2

Fixed

File parse errors were not reported correctly when running pint ci.

v0.17.1

Fixed

Handle 504 Gateway Timeout HTTP responses from Prometheus same as query timeouts and retry with a shorter range query.

v0.17.0

Added

When running pint ci all checks will be skipped if any commit contains [skip ci] or [no ci] string in the commit message.

Changed

By default pint will now parse all files in strict mode, where all rule files must have the exact syntax Prometheus expects:
```
groups:
- name: example
  rules:
  - record: ...
    expr: ...
```
Previous releases were only looking for individual rules so groups object wasn't required. Now pint will fail to read any file that doesn't follow Prometheus syntax exactly. To enable old behaviour add parser { relaxed = ["(.+)", ...]} option in the config file. See Configuration for details. To enable old (relaxed) behaviour for all files add:
```
parser {
  relaxed = ["(.*)"]
}
```

Fixed

Improved promql/vector_matching checks to detect more issues.
Fixed reporting of problems detected on unmodified lines when running pint ci.

v0.16.1

Fixed

Fixed false positive reports from alerts/template check when absent() function is receiving labels from a binary expression.

v0.16.0

Added

When running pint watch exported metric can include owner label for each rule. This is useful to route alerts based on pint_problem metrics to the right team. To set a rule owner add a # pint file/owner $owner comment in a file, to set an owner for all rules in that file. You can also set an owner per rule, by adding # pint rule/owner $owner comment around given rule. To enforce ownership comments in all files pass --require-owner flag to pint lint.

v0.15.7

Fixed

promql/series check no longer runs duplicated checks on source metrics when a query depends on a recording rule added in the same PR.

v0.15.6

Fixed

promql/series check was reporting that a metric stopped being exported when check queries would require a few retries.

v0.15.5

Fixed

promql/series check was reporting both Warning and Bug problems for the same metric when it was using newly added recording rule.

v0.15.4

Fixed

Fixed false positive reports from promql/fragile when foo OR bar is used inside aggregation.

v0.15.3

Fixed

Use more efficient queries for promql/series check.
Fixed YAML parsing panics detected by Go 1.18 fuzzing.

v0.15.2

Fixed

Improved query cache hit rate and added pint_prometheus_cache_hits_total metric to track the number of cache hits.

v0.15.1

Added

When a range query returns query processing would load too many samples into memory error and we retry it with smaller time range cache this information and start with that smaller time range for future calls to speed up running pint watch.

v0.15.0

Changed

Always print the number of detected problems when running pint lint.
promql/series check was refactored and will now detect a range of problems. See promql/series for details.
promql/regexp severity is now Bug instead of a Warning.
promql/rate check will no longer produce warnings, it will only report issues that cause queries to never return anything.

v0.14.0

Added

Allow matching alerting rules by for field - #148. Example:

rule {
  match {
    for = ">= 10m"
  }
}

Regexp matchers used in check rules can now reference rule fields. See Configuration for details.

Changed

Added filename label to pint_problem metric - #170.
Include Prometheus server URI in reported problems.

Fixed

Fixed pint ci handling when a file was added to git and then removed in the next commit.

v0.13.2

Fixed

yaml/parse was using incorrect line numbers for errors caused by duplicated YAML keys.

v0.13.1

Fixed

Don't use fail-over Prometheus servers in case of errors caused by the query itself, like many-to-many matching not allowed.

v0.13.0

Added

yaml/parse error will be raised if a rule file contains duplicated keys, example:

- record: foo
  expr: sum(my_metric)
  expr: sum(my_metric) without(instance)

Changed

prometheus config block now allows to specify fail-over URIs using failover field. If fail-over URIs are set and main URI fails to respond pint will attempt to use them in the order specified until one of them works.
prometheus config block now allows to define how upstream errors are handled using required field. If required is set to true any check that depends on remote Prometheus server will be reported as bug if it's unable to talk to it. If required is set to false pint will only emit warning level results. Default value for required is false. Set it to true if you want to hard fail in case of remote Prometheus issues. Note that setting it to true might block PRs when running pint ci until pint is able to talk to Prometheus again.
Renamed pint/parse to yaml/parse and added missing documentation for it.

v0.12.0

Added

Added pint_last_run_time_seconds and pint_rules_parsed_total metrics when running pint watch.

Changed

promql/comparison only applies to alerts, so it was renamed to alerts/comparison.
Online documentation hosted at cloudflare.github.io/pint was reworked.
alerts/count check will now retry range queries with shorter time window on found duplicate series for the match group ... errors from Prometheus.

v0.11.1

Fixed

pint_prometheus_queries_total and pint_prometheus_query_errors_total metrics were not incremented correctly.

v0.11.0

Added

Added promql/regexp check that will warn about unnecessary regexp matchers.
Added pint_prometheus_queries_total and pint_prometheus_query_errors_total metric when running pint watch.

v0.10.1

Fixed

Fixed a number of bug with promql/vector_matching check.

v0.10.0

Changed

query/series check was renamed to promql/series.

Fixed

Improved the logic of promql/vector_matching check.

v0.9.0

Changed

Removed lines label from pint_problem metric exported when running pint watch.
Multiple match and ignore blocks can now be specified per each rule.

v0.8.2

Added

Export pint_version metric when running pint watch.
Added --min-severity flag to pint watch command.

v0.8.1

Added

Added --max-problems flag to pint watch command.

Changed

Updated Prometheus modules to v2.33.0. This adds support for stripPort template function.

v0.8.0

Added

Added new promql/fragile check.
BitBucket reports will now include a link to documentation.

v0.7.3

Added

--workers flag to control the number of worker threads for running checks.

v0.7.2

Changed

More aggressive range reduction for query processing would load too many samples into memory errors when sending range queries to Prometheus servers.

v0.7.1

Added

Added command filter to match / ignore blocks. This allows to include skip some checks when (for example) running pint watch but include them in pint lint run.

v0.7.0

Added

Cache each Prometheus server responses to minimise the number of API calls.
pint watch will start a daemon that will continuously check all matching rules and expose metrics describing all discovered problems.

Changed

alerts/annotation and rule/label now include required flag value in # pint disable ... comments. Rename # pint disable alerts/annotation($name) to # pint disable alerts/annotation($name:$required) and # pint disable rule/label($name) to # pint disable rule/label($name:$required).
--offline and --disabled flags are now global, use pint --offline lint instead of pint lint --offline.

Fixed

promql/rate, query/series and promql/vector_matching checks were not enabled for all defined prometheus {} blocks unless there was at least one rule {} block.
annotation based match blocks didn't work correctly.

v0.6.6

Fixed

File renames were not handled correctly when running git ci on branches with multiple commits.

v0.6.5

Added

Allow disabling query/series check for individual series using # pint disable query/series(my_metric_name) comments.

v0.6.4

Fixed

Fixed docker builds.

v0.6.3

Fixed

aggregate check didn't report stripping required labels on queries using aggregation with no grouping labels (sum(foo)).
aggregate check didn't test for name and label matches on alert rules.

v0.6.2

Changed

template check will now include alert query line numbers when reporting issues.

v0.6.1

Fixed

Labels returned by absent() are only from equal match types (absent(foo="bar"), not absent(foo=~"bar.+") but alerts/template didn't test for match type when checking for labels sourced from absent() queries.

v0.6.0

Changed

aggregate check was refactored and uses to run a single test for both by and without conditions. As a result this check might now find issues previously undetected. Check suppression comments will need to be migrated:
- # pint disable promql/by becomes # pint disable promql/aggregate
- # pint disable promql/without becomes # pint disable promql/aggregate
- # pint ignore promql/by becomes # pint ignore promql/aggregate
- # pint ignore promql/without becomes # pint ignore promql/aggregate

v0.5.3

Fixed

Fixed false positive reports in aggregate check.

v0.5.2

Added

--no-color flag for disabling output colouring.

Fixed

Fixed duplicated warnings when multiple rule {...} blocks where configured.

v0.5.1

Fixed

Specifying multiple # pint disable ... comments on a single rule would only apply last comment. This now works correctly and all comments will be applied.

v0.5.0

Added

Added alerts/for check that will look for invalid for values in alerting rules. This check is enabled by default.

Changed

comparison check is now enabled by default and require no configuration. Remove comparison{ ... } blocks from pint config file when upgrading.
template check is now enabled by default and require no configuration. Remove template{ ... } blocks from pint config file when upgrading.
rate check is now enabled by default for all configured Prometheus servers. Remove rate{ ... } blocks from pint config file when upgrading.
series check is now enabled by default for all configured Prometheus servers. Remove series{ ... } blocks from pint config file when upgrading.
vector_matching check is now enabled by default for all configured Prometheus servers. Remove vector_matching{ ... } blocks from pint config file when upgrading.

v0.4.4

Added

Support parseDuration function in alert templates added in Prometheus 2.32.0

v0.4.3

Fixed

Fixed series check handling of queries with {__name__="foo"} selectors.

v0.4.2

Fixed

Fixed template check handling of absent calls on aggregated metrics, like absent(sum(nonexistent{job="myjob"})).

v0.4.1

Added

template check will now warn if any template is referencing a label that is not passed to absent(). Example:

{% raw %}
```
- alert: Foo
  expr: absent(foo{env="prod"})
  annotations:
    summary: 'foo metric is missing for job {{ $labels.job }}'
```
{% endraw %}

Would generate a warning since absent() can only return labels that are explicitly passed to it and the above call only passes env label. This can be fixed by updating the query to absent(foo{env="prod", job="bar"}).

v0.4.0

Added

comparison check will now warn when alert query uses bool modifier after condition, which can cause alert to always fire. Example:
```
- alert: Foo
  expr: rate(error_count[5m]) > bool 5
```
Having bool as part of > 5 condition means that the query will return value 1 when condition is met, and 0 when it's not. Rather than returning value of rate(error_count[5m]) only when that value is > 5. Since all results of an alerting rule expr are considered alerts such alert rule could always fire, regardless of the value returned by rate(error_count[5m]).

Fixed

comparison check will now ignore absent(foo) alert queries without any condition.

v0.3.1

Added

--offline flag for pint ci command.

Fixed

Fixed template check panic when alert query had a syntax error.

v0.3.0

Added

rule block can now specify ignore conditions that have the same syntax as match but will disable rule for matching alerting and recording rules #48.
match and ignore blocks can now filter alerting and recording rules by name. record will be used as name for recording rules and alert for alerting rules.

v0.2.0

Added

--offline flag for pint lint command. When passed only checks that don't send any live queries to Prometheus server will be run.
template check will now warn if template if referencing a label that is being stripped by aggregation. Example:

{% raw %}
```
- alert: Foo
  expr: count(up) without(instance) == 0
  annotations:
    summary: 'foo is down on {{ $labels.instance }}'
```
{% endraw %}

Would generate a warning since instance label is being stripped by without(instance).

v0.1.5

Fixed

Fixed file descriptor leak due to missing file Close() #69.

v0.1.4

Changed

Retry queries that error with query processing would load too many samples into memory using a smaller time range.

v0.1.3

Added

vector_matching check for finding queries with incorrect on() or ignoring() keywords.

Fixed

comparison check would trigger false positive for rules using unless keyword.

v0.1.2

Fixed

# pint skip/line place between # pint skip/begin and # pint skip/end lines would reset ignore rules causing lines that should be ignored to be parsed.

v0.1.1

Changed

value check was replaced by template, which covers the same functionality and more. See docs for details.
