Shims the use of AtomicU64 in the main metrics lib so that we can use the library on MIPS and other 32 bit platforms.

Changes the atomic lib to portable-atomic as the atomic-shim no longer provides a complete implementation of the methods we require.

Tested building with target.mipsel-unknown-linux-musl.

Fixes #235

Needs some more work... some of the atomic methods being used aren't available on MIPS either...

The problem I'm faced with here is that fetch_max and fetch_update do not exist in the shimmed AtomicU64. I've created an issue there and will attempt a PR later in the week. Appreciate any other thinking on this too though. Thanks.

One other thought: could we get away with 32 bit hash values for keys?

One other thought: could we get away with 32 bit hash values for keys?

We cannot, no: we need to be able to hold a u64 in order to satisfy std::hash::Hasher::finish.

Could a 32 bit hash be used as an opt-in feature, or even more generally? We then cast the u64 to u32 for the atomic.

Could a 32 bit hash be used as an opt-in feature, or even more generally? We then cast the u64 to u32 for the atomic.

Doing so would imply that we need to drop entropy from the original 64-bit hash, which I don't want to do. Performance is a top priority of metrics, and adding a simple way to effectively/silently truncate the hash values for keys, possibly leading to an increased rate of hash collisions, doesn't seem worth it to me as a shortcut to make this change.

Another crate to try out might be portable-atomic: it's a bit more generalized, has fewer transitive dependencies than atomic-shim, and most importantly, should have support for AtomicU64::fetch_max and AtomicU64::fetch_update.

Thanks. I’ll take a look in the next few days.

I've now updated my PR to use portable-atomic. All appears well given a target.mipsel-unknown-linux-musl build.

Sorry, been a bit preoccupied lately.

Looking it over: I'm happier with this, yes. I'll merge it once CI passes.

Thanks! I'm unsure why that target build is failing though... any ideas?

FYI I tried building the x86_64-unknown-linux-gnu target locally on metrics-tracing-context and all was well...

Yeah, to be honest, I don't know why it's up in arms... but I have to go through a lot of my open-source crates and deal with issues related to a bunch of downstream dependencies switching to the 2021 Edition and breaking CI anyways (😓), so... I'll just merge this for now and do a more thorough pass locally.

Merge changes from fork (#2)
9e8351e 
* fix prometheus metric name and label key sanitizer (metrics-rs#296)

Co-authored-by: Toby Lawrence <tobz@users.noreply.github.com>

* metrics-util: add ability to collect metrics on a per-thread basis via DebuggingRecorder (metrics-rs#299)

Signed-off-by: Toby Lawrence <toby@nuclearfurnace.com>

* (cargo-release) version 0.12.1

* Improve handling of the global recorder instance (metrics-rs#302)

This gets rid of the dangerous `static mut`, adds more comments
about the code, relaxes the orderings and documents the unsoundness
of the `clear` function, in addition to marking it unsafe.

It implements a small once_cell-like abstraction.
