Bug 1359965 - Support and generate tar.gz WPT archive; r=glandium Several years ago there was a single zip file for all test files. Clients would only extract the files they needed. Thus, zip was a reasonable archive format because it allowed direct access to members without having to decompress the entirety of the stream. We have since split up that monolithic archive into separate, domain-specific archives. e.g. 1 archive for mochitests and one for xpcshell tests. This drastically cut down on network I/O required on testers because they only fetched archives/data that was relevant. It also enabled parallel generation of test archives, we shaved dozens of seconds off builds due to compression being a long pole. Despite the architectural changes to test archive management, we still used zip files. This is not ideal because we no longer access specific files in test archives and thus don't care about single/partial member access performance. This commit implements support for generating tar.gz test archives. And it switches the web-platform archive to a tar.gz file. The performance implications for archive generation are significant: before: 48,321,250 bytes; 6.05s after: 31,844,267 bytes; 4.57s The size is reduced because we have a single compression context so data from 1 file can benefit compression in a subsequent file. CPU usage is reduced because the compressor has to work less with 1 context than it does with N. While I didn't measure it, decompression performance should also be improved for the same reasons. And of course network I/O will be reduced. mozharness consumers use a generic method for handling unarchiving. This method automagically handles multiple file extensions. So as long as downstream consumers aren't hard coding ".zip" this change should "just work." MozReview-Commit-ID: LQa5MIHLsms
