Script that checks an Unvanquished release for various possible mistakes.

Optional dependencies (pip): macholib, pefile, pyelftools

Usage:

validate_release.py <zip file>

<zip file> may be the universal zip, or any of the platform-specific or symbols zips contained therein. If the zip file is named according to conventions, the script guesses which one it is. If the file is named differently, the type of zip file to look for can be specified as a second argument (see the usage string in the script).

The script has been tested on Linux and Windows. Pure Python libraries are used to analyze the various binary formats, so it should work on any platform.

Checks performed:

• All native binaries are built with ASLR
• All Breakpad symbol files exist and have some of the expected content
• Hashes in pkg/md5sums match the packages
• Normal file permissions for Unices (ones like on the NaCl files in 0.51.1 could prevent making an installation usable by someone other than the owner)
• Linux binaries have no unexpected changes in dynamic dependencies
• Build IDs in symbol files match chose of binaries (i.e. the symbols actually come from the right binary)
• DEPS graph of DPKs: all deps exist; no cycles; no unused packages

Running the script on the 0.51.1 release produces the following output on stdout as of commit d7c72954:
