Remove duplicate dependencies for rustc itself

[jyn514]

Some things that immediately look promising to remove:

• smallvec 0.6.13, from rustc_workspace_hack (can be upgraded)
• semver 0.9, used for the rustc_ crates where cargo uses 0.10
• env_logger 0.6, used in rustfmt (can be upgraded)

These duplicates were collected with cargo tree -d in the top-level directory of the rust code base.

[workingjubilee]

Cargo.lock can appear deceptive because many of these dependencies ultimately are rooted in e.g. RLS. It's not quite a duplicate per se, but I recently audited all the instances of depending on the byteorder crate, for example, and

1. Most dependents are somewhere in the RLS dependency graph and actually have already moved on, but RLS has not been updated in a while (it is still on tokio v0.1) and so neither has its dependency graph
2. Of those who are not, they are usually depending on it for 1~3 lines
3. Of the two who weren't, one was measureme and it wasn't a huge refactoring job to get rid of it, and I PR'd such in Remove byteorder dependency measureme#125
4. The last instance of it is in regex-automata which is pulled in as part of tracing, and both regex-automata and tracing are looking at 0.2 releases Soon™, so!

smallvec 0.6.13 is actually a similar story as this but actually much more snarled. Its dependency chain looks like

smallvec 0.6.13 <- parking_lot_core 0.6.2 <- parking_lot 0.9.0 <- {
    measureme,
    { jsonrpc-*, tokio-* } <- rls
}

After my PR there, measureme should actually be ready to cut a release which will simplify its position in the dependency graph substantially, but much of the work is going to be in basically reviewing and refactoring RLS. I predict it will actually be easier to remove some non-duplicates.

[matklad]

Note that tokio is in theory removable from RLS. RLS has relatively modest IPC requirements and should be fine with blocking JSON over stdio. However, this might require writing somewhat more code, as IIRC there are no ready-made libraries for blocking IPC.

[workingjubilee]

I think that could still be easier than recursively updating the community dependencies of jsonrpc-* in RLS. RLS is being moved off-of, and I wouldn't want to break it while it is still technically the main RLS, but the dependency on old versions of futures and tokio means that writing a few extra lines for doing the IPC in a direct blocking fashion and simplifying RLS's overall dep state could be much better. This is because RLS is currently in a position where it's not a simple update for tokio either, since jsonrpc-* hasn't fully moved into newer async / futures code yet.

That said, it's possible paritytech/jsonrpc#485 will resolve fully soon and tokio 0.2 will become usable, and moving to blocking JSON IPC would be less of a win then.

[workingjubilee]

jsonrpc was updated to use a more recent tokio and so now rls pulls in tokio 0.2!
...just in time for tokio 1.0!
...whatever!
We now only have one tokio copy. It doesn't matter that it's not the latest because it's one. 🎉

some losses have happened though, e.g.

[[package]]
name = "cargo_metadata"
version = "0.8.2"

[[package]]
name = "cargo_metadata"
version = "0.11.1"

[[package]]
name = "cargo_metadata"
version = "0.12.0"

#84498 also will pull a few deps out of the tree more-or-less permanently.
#84420 pulled smallvec 0.6 out, and should resolve all instances of arrayvec to 0.7 when the next rustc-ap set gets published.
RLS and rustfmt have accepted PRs to bump itertools to 0.9, so those will be up to date when that propagates.

Getting sha-1's duplicates settled seems challenging if attempted, it works like
mdbook -> handlebars -> pest_derive -> pest_generator -> pest_meta -> sha-1 0.8.2
but that would reduce duplication of block-buffer, digest, and opaque-debug.

[workingjubilee]

Also relevant is that, as far as achieving actual goals like "reducing build/test times for rustc" goes, not all deps are in the root Cargo.lock anymore, as other deps can wind up being built/tested. e.g. Cranelift pulled in its own version of byteorder which I factored out in bytecodealliance/wasmtime#2857, but there's probably others. So "just whatever is duplicated in Cargo.lock" is not our only concern, though it might be more relevant to pursue that in depth in a separate issue.

[bjorn3]

The rustc_codegen_cranelift Cargo.lock doesn't contain a lot of dependencies (44 of which 7 are only for some targets), some will be removed by bytecodealliance/wasmtime#2730 once it gets merged (6 I believe. basically all proc macros) and the heaviest dependencies are those specific to Cranelift. Disabling support for the jit mode removes a couple more dependencies.

[workingjubilee]

Yeah, I don't think Cranelift is particularly heavy, and once that's rebased and the update propagates, it will be even lighter. Just more of a general note that there's wins (and dependencies) to be found deeper in the tree.
