chore(internal): add process_tags to APM payload #15146

dubloom · 2025-11-05T14:48:59Z

This PR implements this RFC for the tracing product.

Add process_tags in APM payload. According to the RFC and as the python tracer supports only v0.4 and v0.5 the tag _dd.tags.process is set in the first first span of each trace chunk set.

The set tag are:

entrypoint.workdir. The working dir name, should be the last path segment.
entrypoint.name. The entrypoint of the application. It is the the script name.
entrypoint.type. I'd assume that it can be only script for Python.
entrypoint.basedir. The base dir is the directory where the called executable resides. Should be the last path segment.

implementation seems like overkill for what needs to be implemented. this is going to have a negative performance impact, especially with the introduction of the lock

are there any edge cases/failure scenarios we should be testing?

e.g. what if sys.argv[0] is outside of os.getcwd?

what if the basename of sys.argv[0] doesn't have an extension?

is it possible for Path(sys.argv[0]).resolve() to not have a parent?

addressed in 0428dcd

I'm not sure if you said:

sys.argv[0] is outside of os.getcwd?

as a real example. Because in terms of code, everything would work. Maybe it would not make sense in terms of tag values but this is not something we can control

+class TestProcessTags(TracerTestCase):


we probably want a tearDown to reset process tags to their original configuration value and generated value?

since all of these tests are polluting the global state/configuration and the state stored at the module level of process_tags.

you don't need this test case, you can just roll it into the ones above (have the ones above also create a child span and the snapshot will encode the "only on the root span" for you).

not sure if you care about validating the case with partial flushing?

you could add/update any tests for the TraceTagsProcessor as well, since controlling better the scenarios like partial flushing are pretty basic.

Testing partial is a good idea. I tried to address it in addressed in 0428dcd, tell me if it looks good to you

There's a comment in the RFC that this should be enabled by default if the user also adds DEFAULT_TRACE_EXPERIMENTAL_FEATURES_ENABLED. I'm not sure what that means for Python since we have something called DD_TRACE_EXPERIMENTAL_FEATURES_ENABLED:
https://ddtrace.readthedocs.io/en/stable/configuration.html#DD_TRACE_EXPERIMENTAL_FEATURES_ENABLED, which currently lists runtime metrics as an experimental feature:

dd-trace-py/ddtrace/internal/constants.py

Line 143 in b7a2d2a

class EXPERIMENTAL_FEATURES:

I'm not sure if that's also needed in this PR on top of this new environment variable.

This env variable is meant to be used like:
DD_TRACE_EXPERIMENTAL_FEATURES_ENABLED=DD_RUNTIME_METRICS_ENABLED.

So I don't think that covers our use case.

Is it possible to do a windows version of this in the test suite? Windows path do \ instead of /: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/path#examples .

os.path.basename() uses the path separator of the operating system it’s running on. Therefore, if we want to add a test for Windows, we'll have to run the test on a Windows machine which might be overkill.
