Potential reliability issue on GE export


(Yi Cheng) #1

Hi,

I made a script to extract certain build attributes via the GE export api. Although I do notice that with every 20k-30k builds, with good reproducibility, the sseclient will error out due to “network issue” (because I am not exactly sure which component is at fault between sseclient and GE). I am using sseclient-py recommended by https://docs.gradle.com/enterprise/export-api/#client_libraries.

This is not blocking per se, but could be annoying if we want to build some reliable. Wonder if gradle side could reproduce this with hardening tests.

Example output:

// count, build id, duration, success, tag

Hi Yi,

We’ve not had this issue reported before, which is a soft indication of something environmental.

Can you please generate a support bundle and send that to me. It might be on the larger side, so you might need to share it via Dropbox or similar. You can send the download link to my first name @gradle.com.

  • Is the error message always the same? In particular the numbers in the IncompleteRead(28 bytes read, 3 more expected) part.

  • Does this only happen when consuming the real time feed? Or does it
    happen when consuming historic builds?

  • Are you aware of any proxies between where the client is running and the server? or any other quirky network controls?

The reliability of the Export API is very important to us so I appreciate you raising this issue.
