Finding a specific build log is incredibly slow

I have a script where I am trying to retrieve build logs for all PRs we have that are failing so I can parse the logs and collate the data.

I can get all of the PRs that are failing a particular check with the Github API pretty easily. I end up with detail links which all point to our internal ADO project.

It when I need to pull the logs from ADO that things get really slow. The code basically looks like this:

# PHASE 2: Collect logs for failed LintDiff runs from Azure DevOps
failure_logs = []
ado = get_ado_client()
for run in failed_lint_diff_runs:
    link = run.details_url
    build_id = get_build_id(link)
    build_client = ado.clients_v7_1.get_build_client()
    build_logs = build_client.get_build_logs("internal", build_id)
    for log in build_logs:
        lines = build_client.get_build_log_lines("internal", build_id, log.id)
        if "Starting: LintDiff" in lines[0]:
            print(f"Found LintDiff log for build {build_id} at log {log.id}")
            failure_logs.append(lines)
            break

When I run this, it takes about 20 minutes to run... all of the time is spent repeatedly calling get_build_log_lines to examine just the first line of the build log to see if it is the one I care about. The output looks like:

You can see, we have a lot of build logs, so much of the time is wasted. I couldn't find anything about the build log object that is identifiable. The ID changes all the time, and while in the UI it has a consistent name, that name doesn't seem to be included here. If it were, it would save a ton of time.

Is there a better way to collect this information?

Comienza con las llamadas del cliente Python de Azure DevOps mostradas en el issue: get_build_client(), get_build_logs() y get_build_log_lines(). Comprueba el comportamiento correspondiente de la API de build logs y los metadatos disponibles para identificar un log antes de descargar sus líneas. Se considera terminado cuando se puede encontrar el log de destino LintDiff sin obtener repetidamente el contenido de todos los logs.
