fix: add default time range filter for ListLogEntries API by simonz130 · Pull Request #304 · googleapis/java-logging

simonz130 · 2020-10-29T06:35:10Z

Making the behavior of ListLogEntries API consistent with gcloud: if filter wasn't specified we now attach a default filter of last 24 hours. This will prevent calls from hanging when listing all logs from projects with high log volumes.

Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
Ensure the tests and linter pass
Code coverage does not decrease (if any source code was changed)
Appropriate docs were updated (if necessary)

Fixes #303 ☕️

you should try filter.lower(). "TIMESTAMP" is also allowed

I'm not sure if I'm reading these tests right, but they all seem to include a timestamp as part of the filter. I'd expect to see tests with no filter added to make sure it's added automatically, and tests with "timestamp" or "TIMESTAMP" in the string to make sure those are behaving as expected
