Tool: Latest Chromium ASan builds

May 5, 2021 about Tools

This tool allows you to quickly download the latest Chromium AddressSanitizer (ASan) builds, according to data from the storage bucket and OmahaProxy. Only 64-bit Windows builds are shown.

The Chromium ASan documentation points to the storage bucket directly and instructs users to set the prefix manually to narrow down the platform and commit number. This seems like a lot of overhead for something I do on a regular basis, especially without knowing the latest commit number with an ASan build (not all commits get a build) or after forgetting where to find the latest commit number.

The process above is also prone to human error. Recently I accidentally downloaded a month-old build instead of the latest build. Guess who spent a few hours investigating a fixed UAF bug? 🙋🏻‍♂️

Hope this is as useful to others as it will be to future me. Have feedback? Send me a Tweet or email.
