From 469fa47e0646d8f2ca3237dede8a04568039c7c6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pedro=20J=2E=20Est=C3=A9banez?= Date: Tue, 26 Mar 2019 18:51:13 +0100 Subject: Make all file access 64-bit (uint64_t) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This changes the types of a big number of variables. General rules: - Using `uint64_t` in general. We also considered `int64_t` but eventually settled on keeping it unsigned, which is also closer to what one would expect with `size_t`/`off_t`. - We only keep `int64_t` for `seek_end` (takes a negative offset from the end) and for the `Variant` bindings, since `Variant::INT` is `int64_t`. This means we only need to guard against passing negative values in `core_bind.cpp`. - Using `uint32_t` integers for concepts not needing such a huge range, like pages, blocks, etc. In addition: - Improve usage of integer types in some related places; namely, `DirAccess`, core binds. Note: - On Windows, `_ftelli64` reports invalid values when using 32-bit MinGW with version < 8.0. This was an upstream bug fixed in 8.0. It breaks support for big files on 32-bit Windows builds made with that toolchain. We might add a workaround. Fixes #44363. Fixes godotengine/godot-proposals#400.
