Project FOG uses the
glean_parser to generate code from metric definitions.
It depends on glean-parser from pypi.org
To update the in-tree glean-parser change the version in
./mach vendor python
Important: the glean_parser and all of its dependencies must support Python 3.5, as discussed here. This is the minimum version supported by mach and installed on the CI images for running tests. This is enforced by the version ranges declared in the Python installation manifest.
Version mismatch of the Python dependencies¶
The logic for handling version mismatches is very similar to the one for the Rust crates. See Updating the Glean SDK for details. However, updating Python packages also requires to think about Python 3.5 (and Python 2, still) compatibility.
Keeping versions in sync¶
The Glean SDK and
glean_parser are currently released as separate projects.
However each Glean SDK release requires a specific
When updating one or the other ensure versions stay compatible.
You can find the currently used
glean_parser version in the Glean SDK source tree, e.g. in sdk_generator.sh.
