Defaults to /tmp. ## Setup a nightly job -TODO: Complete with safetynet_job.py setup and usage. +Create a separate checkout of pdfium in a new directory, for example `~/job`. +The safetynet_job.py script will run from this directory. This checkout needs to +be `git pull`'ed when there are changes to the SafetyNet scripts, but otherwise +it can be left alone. + +Create a directory to contain the job results, for example `~/job_results`. In +each run, a `.log` file with the results will be written to this directory and a +subdirectory will be created with the other artifacts. + +Setup a cron job to run safetynet_job.py nightly. The example below runs it at +1:42 AM, over the corpus in two directories: `~/pdf_samples/thousand_pdfs` and +`~/pdf_samples/i18n` + +```shell +@ crontab -e +42 1 * * * bash -lc '~/job/pdfium/testing/tools/safetynet_job.py ~/job_results ~/pdf_samples/thousand_pdfs ~/pdf_samples/i18n --output-to-log >> ~/job_results/cron_nightly.log 2>&1' +``` + +The first time the job runs, it will just create a checkpoint as +`~/job_results/last_revision_covered`. From then on, since a checkpoint is +available, each run will compare performance with the last checkpoint and update +the checkpoint. |
