ui: add configoverride context manager...
ui: add configoverride context manager I feel like this idea might've been discussed before, so please feel free to point me to the right mailing list entry to read about why it should not be done. We have a common pattern of the following code: backup = ui.backupconfig(section, name) try: ui.setconfig(section, name, temporaryvalue, source) do_something() finally: ui.restoreconfig(backup) IMO, this looks better: with ui.configoverride({(section, name): temporaryvalue}, source): do_something() Especially this becomes more convenient when one has to backup multiple config values before doing something. In such case, adding a new value to backup requires codemod in three places.
