Select a name and percentage for the new cohort. Under Cohorts, click Manage, then Create Subcohort of Auto. Upload the new version of the file types. Then commit the changes by clicking Commit Automation Changes. Disable the automatic push by changing the Push Scheduler from LATEST_TO_AUTO to NONE. Submitting a new CL incrementing the version number. Reverting the changes on the Chromium source tree. Rolling back a bad version is best achieved by: (This is important for running new versions on Canary/Dev channel). While Omaha allows rollback through the release manager, the Chrome client will reject updates with lower version numbers. The Component Updater system will notice those files and push them to users within ~6 hours. It will fail if you‘re not a member of since that’s required for access to the GCS bucket. It will ask you to double check its actions before proceeding. % components/safe_browsing/content/resources/push_file_type_proto.py -d out-gn/Debug. Replace the arg with your build directory: In a synced checkout, run the following to generate protos for all platforms and push them to GCS. Wait 1-3 day for this to run on Canary to verify it doesn't crash Chrome. Push it to all users via component update:. 
Edit download_file_types.asciipb and enums.xml. Rendered version of this file: Procedure for adding/modifying file type(s) The metadata described here, and stored in download_file_types.asciipb, will be both baked into Chrome released and pushable to Chrome between releases (via FileTypePolicies class). This describes how to adjust file-type download behavior in Chrome including interactions with Safe Browsing. To get around this, I thought I might enable the GPO to fix their download location (as mentioned above) to their home folder - the only trouble is I can't be so specific as they share a class log-on and then have an individual work folder each in their main home folder.Behavior of Download File Types in Chrome How do I block that location (they cannot browse here as it is already blocked)? 
I have the prompt for download GPO enabled, but for the early years (and even a lot of the later ones) if they don't navigate to their home folder and just press save in the first dialogue box it ends up there.
I have no clue how they're doing it as I can't replicate it - everytime I try to save something it comes up with 'Disabled by your Administrator' or similar depending on the application.Īnyway one thing they can do with Scratch in a Chrome browser, is save a file to this location (not sure where this file is physically though): These are local profiles without UEV / redirection or anything else going on. I have most of the save locations on our pupil ICT suite locked down (C: D: Network etc), but occasionally I do find the odd file on the desktop. Sorry for the old thread resurrection, but I'm having a very similar problem.
