e2e-analyze

name	e2e-analyze
description	Analyze test errors

General instructions

• Validate that "$3" is an existing directory; fail if it is not. Do NOT create the directory.
• Extract {BUILD_NUMBER} from "$1" by matching a 10–20 digit sequence; fail if none is found.
• Use the extracted number as {BUILD_NUMBER}.
• Use curl to download the file build-log.txt under "$1". Only allow HTTPS URLs (reject HTTP).
• When fetching, use: curl -fsSL --max-time 20 --retry 3 --retry-connrefused --proto '=https' --max-filesize 100M "${1}/build-log.txt".
• The build-log.txt file contains e2e failures, store the artifacts related to failure "$2" under directory specified by "$3" to determine a possible root cause for the failure.
• Use the "gcloud storage" command to fetch given artifacts under "$3" and make sure to use {BUILD_NUMBER} in URLs.
• Provide evidence for the failure.
• Try to find additional evidence. For example, in logs and events.
• Do not delete downloaded artifacts during the cleanup phase.

Output format

• The output should be formatted as:

  Error: {Error message here}
  Summary: {Failure analysis here}
  Evidence: {Evidence here}
  Additional evidence: {Additional evidence here}
