6.0.0

  • Generate Rate, Denominator and Numerator metrics for Kotlin and Swift

  • Explicitly skip Rate, Denominator and Numerator metrics for JavaScript. These will cause a build failure by default, but can be turned into warnings on request. Use -s fail_rates=false to enable warning-only mode.

5.1.2

  • BUGFIX: Revert changes made on v5.1.1.

    • The issues addressed by those changes, were non-issues and result of misuse of the APIs.

  • Glinter: Reject metric files if they use unit by mistake. It should be time_unit (#432).

  • Automatically generate a build date when generating build info (#431). Enabled for Kotlin and Swift. This can be changed with the build_date command line option. build_date=0 will use a static unix epoch time. build_date=2022-01-03T17:30:00 will parse the ISO8601 string to use (as a UTC timestamp). Other values will throw an error.

    Example:

    glean_parser translate –format kotlin –option build_date=2021-11-01T01:00:00 path/to/metrics.yaml

4.3.1

  • BUGFIX: Skip tags for code generation (#409)

  • The path to the file that each metric is defined in is now stored on the Metric object in defined_in["filepath"].

2.3.0 (2021-02-17)

  • Leverage the glean_namespace to provide correct import when building for Javascript.

2.2.0 (2021-02-11)

  • The Kotlin generator now generates static build information that can be passed into Glean.initialize to avoid calling the package manager at runtime.

2.1.0 (2021-02-10)

  • Add support for generating Javascript code.

    • The templates added generate metrics and pings code for Glean.js.

2.0.0 (2021-02-05)

  • New versions 2.0.0 of the metrics.yaml and pings.yaml schemas now ship with glean_parser. These schemas are different from version 1.0.0 in the following ways:

    • Bugs must be specified as URLs. Bug numbers are disallowed.

    • The legacy ping names containing underscores are no longer allowed. These included deletion_request, bookmarks_sync, history_sync, session_end, all_pings, glean_*). In these cases, the _ should be replaced with -.

    To upgrade your app or library to use the new schema, replace the version in the $schema value with 2-0-0.

  • Breaking change: It is now an error to use bug numbers (rather than URLs) in ping definitions.

  • Add the line number that metrics and pings were originally defined in the yaml files.

1.29.1 (2020-12-17)

  • BUGFIX: Linter output can now be redirected correctly (1675771).

1.29.0 (2020-10-07)

  • Breaking change: glean_parser will now return an error code when any of the input files do not exist (unless the --allow-missing-files flag is passed).

  • Generated code now includes a comment next to each metric containing the name of the metric in its original snake_case form.

  • When metrics don’t provide a unit parameter, it is not included in the output (as provided by probe-scraper).

1.28.6 (2020-09-24)

  • BUGFIX: Ensure Kotlin arguments are deterministically ordered

1.28.5 (2020-09-14)

  • Fix deploy step to update pip before deploying to pypi.

1.28.4 (2020-09-14)

  • The SUPERFLUOUS_NO_LINT warning has been removed from the glinter. It likely did more harm than good, and makes it hard to make metrics.yaml files that pass across different versions of glean_parser.

  • Expired metrics will now produce a linter warning, EXPIRED_METRIC.

  • Expiry dates that are more than 730 days (~2 years) in the future will produce a linter warning, EXPIRATION_DATE_TOO_FAR.

  • Allow using the Quantity metric type outside of Gecko.

  • New parser configs custom_is_expired and custom_validate_expires added. These are both functions that take the expires value of the metric and return a bool. (See Metric.is_expired and Metric.validate_expires). These will allow FOG to provide custom validation for its version-based expires values.

1.28.3 (2020-07-28)

  • BUGFIX: Support HashSet and Dictionary in the C## generated code.

1.28.2 (2020-07-28)

1.28.1 (2020-07-24)

  • BUGFIX: Add missing column to correctly render markdown tables in generated documentation.

1.28.0 (2020-07-23)

  • Breaking change: The internal ping deletion-request was misnamed in pings.py causing the linter to not allow use of the correctly named ping for adding legacy ids to. Consuming apps will need to update their metrics.yaml if they are using deletion_request in any send_in_pings to deletion-request after updating.

1.27.0 (2020-07-21)

  • Rename the data_category field to data_sensitivity to be clearer.

1.26.0 (2020-07-21)

  • Add support for generating C## code.

  • BUGFIX: The memory unit is now correctly passed to the MemoryDistribution metric type in Swift.

1.24.0 (2020-06-30)

  • BUGFIX: look for metrics in send_if_empty pings. Metrics for these kinds of pings were being ignored.

1.23.0 (2020-06-27)

  • Support for Python 3.5 has been dropped.

  • BUGFIX: The ordering of event extra keys will now match with their enum, fixing a serious bug where keys of extras may not match the correct values in the data payload. See https://bugzilla.mozilla.org/show_bug.cgi?id=1648768.

1.22.0 (2020-05-28)

  • Breaking change: (Swift only) Combine all metrics and pings into a single generated file Metrics.swift.

1.21.0 (2020-05-25)

  • glinter messages have been improved with more details and to be more actionable.

  • A maximum of 10 extra_keys is now enforced for event metric types.

  • BUGFIX: the Lifetime enum values now match the values of the implementation in mozilla/glean.

1.20.4 (2020-05-07)

  • BUGFIX: yamllint errors are now reported using the correct file name.

1.20.3 (2020-05-06)

  • Support for using timing_distribution’s time_unit parameter to control the range of acceptable values is documented. The default unit for this use case is nanosecond to avoid creating a breaking change. See bug 1630997 for more information.

1.20.2 (2020-04-24)

  • Dependencies that depend on the version of Python being used are now specified using the Declaring platform specific dependencies syntax in setuptools. This means that more recent versions of dependencies are likely to be installed on Python 3.6 and later, and unnecessary backport libraries won’t be installed on more recent Python versions.

1.20.1 (2020-04-21)

  • The minimum version of the runtime dependencies has been lowered to increase compatibility with other tools. These minimum versions are now tested in CI, in addition to testing the latest versions of the dependencies that was already happening in CI.

1.20.0 (2020-04-15)

  • Breaking change: glinter errors found during the translate command will now return an error code. glinter warnings will be displayed, but not return an error code.

  • BUGFIX: Fixes an import error in generated Kotlin code.

1.17.1 (2020-02-05)

  • The Kotlin linter detekt is now run during CI, and for local testing if installed.

  • Python 3.8 is now tested in CI (in addition to Python 3.7). Using tox for this doesn’t work in modern versions of CircleCI, so the tox configuration has been removed.

  • yamllint has been added to test the YAML files on CI.

  • ⚠ Metric types that don’t yet have implementations in glean-core have been removed. This includes enumeration, rate, usage, and use_counter, as well as many labeled metrics that don’t exist.

  • Allow a Swift lint for generated code

  • New lint: Restrict what metric can go into the baseline ping
