Do not use open64 #326

kraj · 2022-12-29T05:51:24Z

glibc is providing open64 and other lfs64 functions but musl aliases them to normal equivalents since off_t is always 64-bit on musl, therefore check for target env along when target OS is linux before using open64, this is more available. Latest Musl has made these namespace changes [1]

Why do we ever need to use open64 in the first place? Since we never seek it seems like we should just avoid the conditional logic.

I am fine by using open, I was trying to fix just musl case, but if we think its better to use just open I can update the patch

Why do we ever need to use open64 in the first place?

It's likely we have inherited it from std, but I agree that we probably do not need it. If @josephlr agrees, we should simply use open.

What does libstd do for musl targets?

What does libstd do for musl targets?

The change to drop/deprecate LFS64 functions in musl is recent and has not yet made it to a GA release.
I will be fixing it in libstd-rs as well see rust-lang/rust#106246

It's likely we have inherited it from std, but I agree that we probably do not need it. If @josephlr agrees, we should simply use open.

Looking through the various documentation, the only difference (if any) is the presence of O_LARGEFILE. That flag isn't relevant to us, as we are only opening a device (not a real file), so we never care about overflowing off_t.

Let's change this patch to just unconditionally use open.

If you rebase this PR onto the latest master, the tests should be passing.

cool. Uploaded a new version of PR. Lets see

This fixes the build with musl-1.2.4, for those that are still experiencing issues these steps should resolve them: 1. Downgrade to musl-1.2.3 2. Rebuild dev-lang/rust with these patches 3. Upgrade to musl-1.2.4 again 4. Rebuild rust with USE=system-bootstrap At this point USE=system-boostrap will be required with >= musl-1.2.4 until uptream merges these patches and updates their boostrap. This was tested with musl-1.2.3, musl-1.2.4 and glibc-2.37-r3.
