2017-09-29Auto merge of #44174 - jimmycuadra:try-from-infallible, r=sfacklerbors-0/+8
Add blanket TryFrom impl when From is implemented. Adds `impl<T, U> TryFrom<T> for U where U: From<T>`. Removes `impl<'a, T> TryFrom<&'a str> for T where T: FromStr` (originally added in #40281) due to overlapping impls caused by the new blanket impl. This removal is to be discussed further on the tracking issue for TryFrom. Refs #33417. /cc @sfackler, @scottmcm (thank you for the help!), and @aturon

Allow replacing HashMap entries This is an obvious API hole. At the moment the only way to retrieve an entry from a `HashMap` is to get an entry to it, remove it, and then insert a new entry. This PR allows entries to be replaced.

2017-09-23Rollup merge of #44712 - oconnor663:copy_test, r=GuillaumeGomezCorey Farwell-1/+2
fix an incorrect assertion in the doc example for `std::io::copy` I think this wasn't caught by CI because the `foo` wrapper function was only defined and not called. This seems to be the norm for doc examples that define a `foo` function. Is that on purpose?
2017-09-23Rollup merge of #44648 - Havvy:doc-size_of, r=dtolnayCorey Farwell-0/+8
Expand size_of docs This PR does 3 things. 1. Adds a description of what pointer size means to the primitive pages for usize and isize. 2. Says the general size of things is not stable from compiler to compiler. 3. Adds a table of sizes of things that we do guarantee. As this is the first table in the libstd docs, I've included a picture of how that looks. ![](https://i.imgur.com/YZ6IChH.png?1)

Retain suid/sgid/sticky bits in Metadata.permissions Most users would expect set_permissions(Metadata.permissions()) to be non-destructive. While we can't guarantee this, we can at least pass the needed info to chmod. Also update the PermissionsExt documentation to disambiguate what it contains, and to refer to the underlying value as `st_mode` rather than its type `mode_t`. Closes #44147

Correctly bubble up errors from libbacktrace Previously the first part of this code didn't check for a null pointer and blindly passed it back down, causing a segfault if libbacktrace failed to initialise. I've changed this to check and bubble up the error if relevant. Suggested diff view: https://github.com/rust-lang/rust/pull/44525/files?w=1

hide internal types/traits from std docs via new #[doc(masked)] attribute Fixes #43701 (hopefully for good this time) This PR introduces a new parameter to the `#[doc]` attribute that rustdoc looks for on `extern crate` statements. When it sees `#[doc(masked)]` on such a statement, it hides traits and types from that crate from appearing in either the "Trait Implementations" section of many type pages, or the "Implementors" section of trait pages. This is then applied to the `libc`/`rand`/`compiler_builtins` imports in libstd to prevent those crates from creating broken links in the std docs. Like in #43348, this also introduces a feature gate, `doc_masked`, that controls the use of this parameter. To view the std docs generated with this change, head to https://tonberry.quietmisdreavus.net/std-43701/std/index.html.
2017-09-18Rollup merge of #44651 - bluss:document-thread-name-no-nuls, r=steveklabnikAlex Crichton-0/+7
Document thread builder panics for nul bytes in thread names This seems to have been undocumented. Mention this where the name is set (Builder::name) and where the panic could happen (Builder::spawn). Thread::new is private and I think the builder is the only user where this matters. A short comment was added to "document" Thread::new too.

2017-09-18Rollup merge of #44466 - clarcharr:cow_error, r=alexcrichtonAlex Crichton-0/+15
Add Cow<str> -> Box<Error> impls. Considering how impls exist for `String` and `&str`, it makes sense to also add an impl for `Cow<str>` as well. This would allow converting `String::from_utf8_lossy` directly into a `Box<Error>` or `io::Error` without having to add an extra `into_ownd()`.

2017-09-16Rollup merge of #44609 - jonhoo:hash-alloc, r=steveklabnikAlex Crichton-0/+6
Mention that HashMap::new and HashSet::new do not allocate The docs for `HashMap::with_capacity` and `HashSet::with_capacity` already say that > If `capacity` is 0, the hash map/set will not allocate. However, the docs for `::new` do not say that the initial capacity is 0, and thus promise that a call to `::new` alone does not allocate. This PR fixes that.
2017-09-16Rollup merge of #44395 - jcdyer:ip-constructors, r=alexcrichtonAlex Crichton-1/+89
Ipv4Addr and Ipv6Addr convenience constructors. Introduce convenience constructors for common types. This introduces the following constructors: * Ipv6Addr::localhost() * Ipv6Addr::unspecified() * Ipv4Addr::localhost() * Ipv4Addr::unspecified() The recently added `From` implementations were nice for avoiding the fallibility of conversions from strings like `"127.0.0.1".parse().unwrap()`, and `"::1".parse().unwrap()`, but while the Ipv4 version is roughly comparable in verbosity, the Ipv6 version lacks zero-segment elision, which makes it significantly more awkward: `[0, 0, 0, 0, 0, 0, 0, 0].into()`. While there isn't a clear way to introduce zero elision to type that can infallibly be converted into Ipv6 addresses, this PR resolves the problem for the two most commonly used addresses, which, incidentally, are the ones that suffer the most from the lack of zero-segment elision. This change is dead simple, and introduces no backwards incompatibility.

2017-09-16Auto merge of #43017 - durka:stabilize-const-invocation, r=eddybbors-0/+13
Individualize feature gates for const fn invocation This PR changes the meaning of `#![feature(const_fn)]` so it is only required to declare a const fn but not to call one. Based on discussion at #24111. I was hoping we could have an FCP here in order to move that conversation forward. This sets the stage for future stabilization of the constness of several functions in the standard library (listed below), so could someone please tag the lang team for review. - `std::cell` - `Cell::new` - `RefCell::new` - `UnsafeCell::new` - `std::mem` - `size_of` - `align_of` - `std::ptr` - `null` - `null_mut` - `std::sync` - `atomic` - `Atomic{Bool,Ptr,Isize,Usize}::new` - `once` - `Once::new` - primitives - `{integer}::min_value` - `{integer}::max_value` Some other functions are const but they are also unstable or hidden, e.g. `Unique::new` so they don't have to be considered at this time. After this stabilization, the following `*_INIT` constants in the standard library can be deprecated. I wasn't sure whether to include those deprecations in the current PR. - `std::sync` - `atomic` - `ATOMIC_{BOOL,ISIZE,USIZE}_INIT` - `once` - `ONCE_INIT`
