Bug #74395 [Opn]: Support 4g files in stream_copy_to_stream() on 32 bit php builds

Edit report at https://bugs.php.net/bug.php?id=74395&edit=1 ID: 74395 Updated by: ab@php.net Reported by: maggus dot staab at googlemail dot com Summary: Support 4g files in stream_copy_to_stream() on 32 bit php builds Status: Open Type: Bug Package: Streams related PHP Version: 7.1.3 Block user comment: N Private report: N New Comment: @spam2 well, 2017 and still someone cares about 32-bit :) But joke aside, you can simply benchmark 64-bit math on 32-bit platform, to see diff. It can also be hardly worth the efforts to do big refactorings or even tricks, where modern RPI or others ship with a 64-bit processor, and eventually 32-bit will die out same way it did already for desktops, etc. Thanks.

To have 64-bit integers always is much bigger topic than just changing the datatype. That would mean a significant performance impact, and aslo things like date, file stat, PHP streams, external libs and many portability cases would require a deep refactoring in PHP. For stat - well, that's an issue, for date it's still ok. The suggested string conversions in the case look not justified. LFS is not something required every day, so performance is more relevant. In some cases it is solvable with a completely sane approach like listed in the first comment, some workarounds for stat are also possible, even not nice. I would tend to set this to won't fix therefore, as it sohuld be either some proper core solution, or 64-bit is fully suitable for the goals otherwise. Thanks. ------------------------------------------------------------------------ [2017-04-10 12:41:19] maggus dot staab at googlemail dot com in https://github.com/nextcloud/server/issues/1707#issuecomment-292937033 it was pointed out why 32 bit builds are used in the first place: "Most SBCs such as Raspberry Pi and Odroid devices still rely on 32 Bit. Therefore this change is a real big thing for those." ------------------------------------------------------------------------ [2017-04-09 09:52:56] spam2 at rhsoft dot net the better question is why is PHP on 32bit limited that way? couldn't it use longint as other applications do? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
