WSGI Preload
Preload your WSGI applications with specified URLs during startup.
Add this to the end of your .wsgi file:
:::python
import wsgipreload
wsgipreload.preload(application, urls=['/', '/foo', '/bar'])
If you are using mod_wsgi, specify the process-group and application-group on your WSGIScriptAlias directive so that it will preload properly. The process-group must match what you specify with WSGIProcessGroup in your config file. Details at https://modwsgi.readthedocs.io/en/develop/release-notes/version-3.0.html#features-added (section 2)
WSGIScriptAlias / /etc/httpd/conf.d/myapp.wsgi process-group=myapp application-group=%{GLOBAL}
Bonus! A helper function is included to pick a few URLs from the beginning of a log file. Use this if you don't want to hard-code all the URLs into your wsgi file.
:::python
import wsgipreload
urls = {'/'}
try:
with open('/var/local/log/httpd-access_log') as log_file:
urls |= wsgipreload.urls_from_log(log_file, num=5)
except Exception as e:
print("preload error on logs")
import traceback
traceback.print_exc()
wsgipreload.preload(application, urls=urls)
