undefined reference to linker error when using dylibs

When including mongodb (2.0.0-alpha) into a dylib'd crate that is included in an application, the linker is failing to resolve all references. It is fine when using mongodb (1.0) which makes me think this is something that tokio 1.0 is bringing to light.

This seems similar to #67276 except the workarounds it suggested at the time do not work.

Code

Due to the nature of this making a truly small example is quite challenging, I assume isolating tokio 1.2 out might work? But anyway for now, an repo for the example is here:

Hi @jonas-schievink, could you let me know how small the example needs to be? I have managed to shrink it to just reqwest & tokio, but might be able to get it much smaller assuming I dont need intimate compiler knowledge in order to guess what the issue could potentially be.
https://github.com/alexkornitzer/dylib-errors/tree/error/tokio

Ideally it would not contain any external dependencies

Okay let me see if I can isolate it down further, but it might be beyond me.

Musings

Not managed to reduce it down yet but I have observed the following which seems interesting, when using reqwest "0.11" which fails the libshared.so tries to link against libhyper-*.so:

        linux-vdso.so.1 (0x00007fff2f1bd000)
	libhyper-e9510aa4920192e8.so => not found
	libstd-6f77337c1826707d.so => not found
	libssl.so.1.1 => /usr/lib/libssl.so.1.1 (0x00007f0536a4c000)
	libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1 (0x00007f053676e000)
	libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f0536754000)
	libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f0536733000)
	libc.so.6 => /usr/lib/libc.so.6 (0x00007f0536564000)
	/usr/lib64/ld-linux-x86-64.so.2 (0x00007f0537707000)
	libdl.so.2 => /usr/lib/libdl.so.2 (0x00007f053655d000)

but if we drop to reqwest "0.10" which succeeds then this .so is missing:

	linux-vdso.so.1 (0x00007ffea26f3000)
	libstd-6f77337c1826707d.so => not found
	libssl.so.1.1 => /usr/lib/libssl.so.1.1 (0x00007f8294541000)
	libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1 (0x00007f8294263000)
	libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f8294249000)
	libpthread.so.0 => /usr/lib/libpthread.so.0 (0x00007f8294228000)
	libdl.so.2 => /usr/lib/libdl.so.2 (0x00007f8294221000)
	libc.so.6 => /usr/lib/libc.so.6 (0x00007f8294052000)
	/usr/lib64/ld-linux-x86-64.so.2 (0x00007f8295434000)

and if we try and bring hyper "0.14" straight into the shared lib we get dep tree errors:

error: cannot satisfy dependencies so `hyper` only shows up once
  |
  = help: having upstream crates all available in one format will likely make this go away

error: aborting due to previous error

error: could not compile `serverctl`

but not with hyper "0.13", I wonder if this dep tree issue is the problem?

@jonas-schievink

Hey @jonas-schievink,

Right got it, so its looks like the issue is when you have the following:

application <- shared (dylib) <- foo (rlib) <- bar (["lib", "staticlib", "cdylib"])

where shared is accessing bar by calling foo::bar where foo re-exports bar.

---bar
pub struct Bar;
pub fn bar() -> Bar {
  Bar
}

---foo
pub use bar::bar;
pub struct Foo;
pub fn foo() -> Foo {
  Foo
}

--shared
pub struct Test;
impl Test {
  pub fn new() -> Self {
    let _ = foo::foo();
    let _ = foo::bar();
    Self
  }
}

--app
fn main() {
  let _ = shared::Test::new();
}

I have a minimal example here: https://github.com/alexkornitzer/dylib-errors/tree/error/nested

Bisected, but this goes back to at least 2018-01-01. I ran cargo-bisect-rustc --test-dir=. --start=<date> with date being the first day of 2018, 2019, and 2020. Got errors of the form:

ERROR: the start of the range (nightly-<date>) must not reproduce the regression

We would like the compiler team to have a closer look at this (tomorrow during the meeting) to help assessing the implicatons (Zulip discussion)

Revert "Upgrade reqwest, warp and tokio"

In our project we use rustc nightly-2021-10-15 and we encountered this issue while trying to upgrade from hyper 0.13, warp 0.2, reqwest 0.10 and tokio 0.2 to hyper 0.14, warp 0.3, reqwest 0.11 and tokio 1.2. Is there any workaround other than downgrading those libraries?

@fpoli

@fpoli I am not too familiar with this issue, but I am wondering if @alexkornitzer workaround in alexkornitzer/hyper@1199048 would help (assuming is it ok for you to vendor hyper, which might not as well)

Thanks! So, that would solve the issue in hyper, but it cannot be upstreamed because hyper also wants to compile to a library usable from C. In our case sticking with the old version of the libraries is still preferable (for now).

Make protocol authentication optional behind a feature flag.

from conversation above

We may be able to fix that "arguably a bug", because dylibs are rare in practice now, most of crate searches will not encounter a dylib candidate.

It sounds like this might be the right next step. I'm already spending some amount of time looking at linker issues (and this is already assigned to me), so I can continue down this path.

(We might want an MCP for the suggested change, in any case.)

Opened #113695 with a fix for what I am pretty sure is the root cause here. (The test I added fails with the same linker issue before that PR at least.)

Auto merge of #113695 - bjorn3:fix_rlib_cdylib_metadata_handling, r=p…
