class sans.guiframe.version.VersionChecker(version_url)

Bases: object

Class of objects used to obtain the current version of an application from the deployment server. A sub process is started to read the URL associated with the version number. The version number is written on file locally before the reading process ends, then read when the version number is requested.

The reading of the URL is put in a separate process so that it doesn’t affect the performance of the application and can be managed and stopped at any time.

get_version()

Returns the last version number that was read from the server.

is_complete()

Method used to poll the reading process. The process will be killed if the wait time is longer than a predefined maximum. This method should always be called before get_version() to ensure accuracy of the version number that is returned.
