Re^4: Compressed content module

GZip magic is easy - The first two bytes are "\x1f\x8b". You can also check for compress which I recall is "\x1f\x9b" though you may want to check.

__SIG__
use B;
printf "You are here %08x\n", unpack "L!", unpack "P4", pack
  "L!", B::svref_2object(sub{})->OUTSIDE;

'easy ' ne 'cheap'. It is certainly easy (thanks for the magic), but it's more expensive than doing an rindex on the filename. `-- I'm not belgian but I play one on TV.`	[reply]

And I thought you'd just suggesting running file(1) on the file. So between a call to file(1) and just reading the first two bytes which are going to be read anyway... I don't see how that's particularly expensive. But then all this only applies if you want to detect GZip/compress files which don't use a .gz/.Z extension. `__SIG__ use B; printf "You are here %08x\n", unpack "L!", unpack "P4", pack "L!", B::svref_2object(sub{})->OUTSIDE;` [download]	[reply] [d/l]

First off it's all moot, this thread started from my misreading the code and thinking he was checking to see if the filename ended in .gz. Secondly, no I did not suggest using file, I said do something like file. Thirdly, while the file will be being read (and so doing the test may preload it into the cache), the bytes read will have to be discarded making that read otherwise worthless. But again, it's all irrelevant. We now return you to youre regularly scheduled NodeReaper-watching.; `-- I'm not belgian but I play one on TV.`	[reply]
