[Перевод] Почему GZIP сыпал исключениями только в жару и в дождь

В квартире стояла летняя жара. Впрочем, ненадолго: хозяин квартиры как раз привез мне кондиционер, и его пора было запускать. Через несколько недель Я писал на C# программу для распаковки gzip-файлов и неожиданно поймал странное исключение, из которого следовало, что архив поврежден. Ситуация выглядела дико: ошибка намекала на поврежденный архив, хотя сам файл не выглядел реально битым. Сказать, что это напрягало значит ничего не сказать...

Oh, joy! Yet another "groundbreaking" tool to tell us the OS that made our #gzip file. 🥳 Because who doesn't lay awake at night pondering over gzip metadata? Thanks, Evan, for saving us from this burning mystery. 🚀🙄

I was surprised to learn that gzip streams encode which operating system did the compression. I built a little tool, "gzpeek", to inspect this metadata (and more): https://evanhahn.com/introducing-gzpeek/

Vergleich von Archivierung und Kompression unter Linux: tar/star, gzip, bzip2, xz und zip

Playing around with compressing a directory structure full of XML files which are about 2MB each (one per directory) and which have a lot of commonality.

It included about 14GB of files in total. With gzip/bzip2/zstd/zip it goes down to ~1GiB (#gzip -> zstd -> bzip2 in order of decreasing size). With #xz it went down to about 67MiB. Huge difference for this use case. Decompressing it was MUCH faster with xz (5.0s vs 33.2s when writing to /dev/null - xz took 5X longer to compress than pigz)

Did you know that #gzip streams may contain filenames?

🎈 Ah, the timeless quest to understand #Deflate by manually decoding a #GZIP file—because clearly, using a computer to do what it's designed for is just too mainstream. 🤓 Meanwhile, Wikipedia does all the heavy lifting, turning an exercise in #compression into an exercise in redundancy. 📜💥

🎉 Behold, the groundbreaking revelation: #Xz is not the Holy Grail of data formats! 🚀 Apparently, using xz for digital preservation is like using a sieve as a bucket—bound to fail. Who knew? 🤦‍♂️ Stick to #bzip2, #gzip, or #lzip if you want actual functionality and avoid sinking your data into the abyss of inadequacy. 🔍💾

static compression for #brotli
and #zstd is enabled on the instance (also #gzip ofc)

Running of few tests I haven't noticed any increasing in errors output / served to other servers. Will keep an eye on logs .

@ermo

I'm very slowly creeping towards having checksum files auto-built. There's a missing part that needs to be done.

But I'm at least over one initial hurdle of switching from pax -z to pax -j. Not that that helps in the #FreeBSD 10 case because FreeBSD 10's pax does not have -j.

(Make an archive with -z and it isn't idempotent, because #gzip has a timestamp.)

So there's still the installing #GhostBSD mountain to climb, and seeing whether that has pax -j yet. (-:

Today I had a quick look at compression speed of the various compression algorithms in #UnrealEngine.

In my use case, speed is more important than compression ratio, so I had COMPRESS_BiasSpeed set.

To little surprise, #gzip and #zlib took about the same time, and #lz4 was a lot slower.

The big surprise was #Oodle, which was faster than all others. By a lot.

So, if you are compressing data in your Unreal game at runtime, you might want to check if Oodle is an option for you.
