2020-08-03Fix async-std at the price of breaking half the test suiteJoshua Nelson-119/+29
- Don't mark impl trait as an error
2020-08-02Auto merge of #74826 - matklad:mbe-fragment, r=petrochenkovbors-339/+319
Introduce NonterminalKind for more type-safe mbe parsing It encapsulate the (part of) the interface between the parser and macro by example (macro_rules) parser. The second bit is somewhat more general `parse_ast_fragment`, which is the reason why we keep some `parse_xxx` functions as public.
2020-08-02Auto merge of #74963 - JohnTitor:ptn-ice, r=petrochenkovbors-56/+146
Fix ICEs with `@ ..` binding This reverts #74557 and introduces an alternative fix while ensuring that #74954 is not broken. The diagnostics are verbose though, it fixes three related issues. cc #74954, #74539, and #74702

2020-08-03Rollup merge of #75057 - Mark-Simulacrum:avoid-long-print, r=alexcrichtonYuki Okushi-1/+3
Avoid dumping rustc invocations to stdout These are quite long, usually, and in most cases not interesting. On smaller terminals they can take up more than a full page of output, hiding the error diagnostics emitted.
2020-08-03Rollup merge of #75054 - cjgillot:rename-depkind, r=petrochenkovYuki Okushi-35/+35
Rename rustc_middle::cstore::DepKind to CrateDepKind It is ambiguous with DepGraph's own DepKind.

2020-08-03Rollup merge of #74874 - ssomers:btree_cleanup_8, r=Mark-SimulacrumYuki Okushi-8/+16
BTreeMap: define forget_type only when relevant Similar to `forget_node_type` for handles. No effect on generated code, apart maybe from the superfluous calls that might not have been optimized away. r? @Mark-Simulacrum

2020-08-03Rollup merge of #74762 - ssomers:btree_no_root_in_remove_kv_tracking, ↵Yuki Okushi-52/+405
r=Mark-Simulacrum BTreeMap::drain_filter should not touch the root during iteration Although Miri doesn't point it out, I believe there is undefined behaviour using `drain_filter` when draining the 11th-last element from a tree that was larger. When this happens, the last remaining child nodes are merged, the root becomes empty and is popped from the tree. That last step establishes a mutable reference to the node elected root and writes a pointer in `node::Root`, while iteration continues to visit the same node. This is mostly code from #74437, slightly adapted.
2020-08-03Rollup merge of #74686 - ssomers:btree_cleanup_3, r=Mark-SimulacrumYuki Okushi-10/+3

Deduplicate `::` -> `:` typo errors Deduplicate errors caused by the same type ascription typo, including ones suggested during parsing that would get reported again during resolve. Fix #70382.

2020-08-02Auto merge of #74972 - second-state:wasi-right-fix, r=KodrAusbors-0/+1
Fix std::fs::File::metadata permission on WASI target Previously `std::fs::File::metadata` on wasm32-wasi would call `fd_filestat_get` to get metadata associated with fd, but that fd is opened without RIGHTS_FD_FILESTAT_GET right, so it will failed on correctly implemented WASI environment. This change instead to add the missing rights when opening an fd.

Use a slice pattern instead of rchunks_exact(_).next() This is a minor cleanup, but trying a single-use `rchunks` iterator can be more directly matched with a slice pattern, `[.., a, b]`.

2020-08-01Auto merge of #74605 - rust-lang:vec-leak, r=Amanieubors-6/+4
Stabilize Vec::leak as a method Closes https://github.com/rust-lang/rust/issues/62195 The signature is changed to a method rather than an associated function: ```diff -pub fn leak<'a>(vec: Vec<T>) -> &'a mut [T] +pub fn leak<'a>(self) -> &'a mut [T] ``` The reason for `Box::leak` not to be a method (`Deref` to an arbitrary `T` which might have its own, different `leak` method) does not apply.

2020-08-01Auto merge of #74726 - oli-obk:tracing, r=Mark-Simulacrumbors-89/+161
Move from `log` to `tracing` The only visible change is that we now get timestamps in our logs: ``` Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: skipping replace of Rvalue::Use(const () because it is already a const Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: propagated into _2 Jul 24 18:41:01.065 TRACE rustc_mir::transform::const_prop: visit_constant: const () ``` This PR was explicitly designed to be as low-impact as possible. We can now move to using the name `tracing` insteads of `log` on a crate-by-crate basis and use any of the other tracing features where desirable. As far as I can tell this will allow tools to seamlessly keep working (since they are using `rustc_driver::init_log...`). This is the first half of step 1 of the accepted `tracing` MCP (https://github.com/rust-lang/compiler-team/issues/331)
