2015-01-26std: Rename io to old_ioAlex Crichton-757/+0
In preparation for the I/O rejuvination of the standard library, this commit renames the current `io` module to `old_io` in order to make room for the new I/O modules. It is expected that the I/O RFCs will land incrementally over time instead of all at once, and this provides a fresh clean path for new modules to enter into as well as guaranteeing that all old infrastructure will remain in place for some time. As each `old_io` module is replaced it will be deprecated in-place for new structures in `std::{io, fs, net}` (as appropriate). This commit does *not* leave a reexport of `old_io as io` as the deprecation lint does not currently warn on this form of use. This is quite a large breaking change for all imports in existing code, but all functionality is retained precisely as-is and path statements simply need to be renamed from `io` to `old_io`.

2015-01-20std: Rename Show/String to Debug/DisplayAlex Crichton-2/+2
This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436

2015-01-03Remove deprecated functionalityAlex Crichton-13/+5
This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-2/+3
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them.

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-1/+1
This commit is a second pass stabilization for the `std::comm` module, performing the following actions: * The entire `std::comm` module was moved under `std::sync::mpsc`. This movement reflects that channels are just yet another synchronization primitive, and they don't necessarily deserve a special place outside of the other concurrency primitives that the standard library offers. * The `send` and `recv` methods have all been removed. * The `send_opt` and `recv_opt` methods have been renamed to `send` and `recv`. This means that all send/receive operations return a `Result` now indicating whether the operation was successful or not. * The error type of `send` is now a `SendError` to implement a custom error message and allow for `unwrap()`. The error type contains an `into_inner` method to extract the value. * The error type of `recv` is now `RecvError` for the same reasons as `send`. * The `TryRecvError` and `TrySendError` types have had public reexports removed of their variants and the variant names have been tweaked with enum namespacing rules. * The `Messages` iterator is renamed to `Iter` This functionality is now all `#[stable]`: * `Sender` * `SyncSender` * `Receiver` * `std::sync::mpsc` * `channel` * `sync_channel` * `Iter` * `Sender::send` * `Sender::clone` * `SyncSender::send` * `SyncSender::try_send` * `SyncSender::clone` * `Receiver::recv` * `Receiver::try_recv` * `Receiver::iter` * `SendError` * `RecvError` * `TrySendError::{mod, Full, Disconnected}` * `TryRecvError::{mod, Empty, Disconnected}` * `SendError::into_inner` * `TrySendError::into_inner` This is a breaking change due to the modification of where this module is located, as well as the changing of the semantics of `send` and `recv`. Most programs just need to rename imports of `std::comm` to `std::sync::mpsc` and add calls to `unwrap` after a send or a receive operation. [breaking-change]

2014-12-08auto merge of #19378 : japaric/rust/no-as-slice, r=alexcrichtonbors-13/+13
Now that we have an overloaded comparison (`==`) operator, and that `Vec`/`String` deref to `[T]`/`str` on method calls, many `as_slice()`/`as_mut_slice()`/`to_string()` calls have become redundant. This patch removes them. These were the most common patterns: - `assert_eq(test_output.as_slice(), "ground truth")` -> `assert_eq(test_output, "ground truth")` - `assert_eq(test_output, "ground truth".to_string())` -> `assert_eq(test_output, "ground truth")` - `vec.as_mut_slice().sort()` -> `vec.sort()` - `vec.as_slice().slice(from, to)` -> `vec.slice(from_to)` --- Note that e.g. `a_string.push_str(b_string.as_slice())` has been left untouched in this PR, since we first need to settle down whether we want to favor the `&*b_string` or the `b_string[]` notation. This is rebased on top of #19167 cc @alexcrichton @aturon

2014-12-06auto merge of #19431 : erickt/rust/buf-writer-error, r=alexcrichtonbors-17/+27
Previously, `BufWriter::write` would just return an `std::io::OtherIoError` if someone attempted to write past the end of the wrapped buffer. This pull request changes the error to support partial writes and return a `std::io::ShortWrite`, or an `io::io::EndOfFile` if it's been fully exhausted. I've also optimized away a bounds check inside `BufWriter::write`, which should help shave off some nanoseconds in an inner loops.

2014-11-23Rename unwrap functions to into_innerAlex Crichton-3/+11
This change applies the conventions to unwrap listed in [RFC 430][rfc] to rename non-failing `unwrap` methods to `into_inner`. This is a breaking change, but all `unwrap` methods are retained as `#[deprecated]` for the near future. To update code rename `unwrap` method calls to `into_inner`.

2014-11-18implement Writer for Vec<u8>Daniel Micay-0/+11
The trait has an obvious, sensible implementation directly on vectors so the MemWriter wrapper is unnecessary. This will halt the trend towards providing all of the vector methods on MemWriter along with eliminating the noise caused by conversions between the two types. It also provides the useful default Writer methods on Vec<u8>. After the type is removed and code has been migrated, it would make sense to add a new implementation of MemWriter with seeking support. The simple use cases can be covered with vectors alone, and ones with the need for seeks can use a new MemWriter implementation.

2014-11-06Prelude: rename and consolidate extension traitsAaron Turon-2/+2
This commit renames a number of extension traits for slices and string slices, now that they have been refactored for DST. In many cases, multiple extension traits could now be consolidated. Further consolidation will be possible with generalized where clauses. The renamings are consistent with the [new `-Prelude` suffix](https://github.com/rust-lang/rfcs/pull/344). There are probably a few more candidates for being renamed this way, but that is left for API stabilization of the relevant modules. Because this renames traits, it is a: [breaking-change] However, I do not expect any code that currently uses the standard library to actually break. Closes #17917
2014-11-01collections: Remove all collections traitsAlex Crichton-3/+1
As part of the collections reform RFC, this commit removes all collections traits in favor of inherent methods on collections themselves. All methods should continue to be available on all collections. This is a breaking change with all of the collections traits being removed and no longer being in the prelude. In order to update old code you should move the trait implementations to inherent implementations directly on the type itself. Note that some traits had default methods which will also need to be implemented to maintain backwards compatibility. [breaking-change] cc #18424
2014-10-29Rename fail! to panic!Steve Klabnik-2/+2
https://github.com/rust-lang/rfcs/pull/221 The current terminology of "task failure" often causes problems when writing or speaking about code. You often want to talk about the possibility of an operation that returns a Result "failing", but cannot because of the ambiguity with task failure. Instead, you have to speak of "the failing case" or "when the operation does not succeed" or other circumlocutions. Likewise, we use a "Failure" header in rustdoc to describe when operations may fail the task, but it would often be helpful to separate out a section describing the "Err-producing" case. We have been steadily moving away from task failure and toward Result as an error-handling mechanism, so we should optimize our terminology accordingly: Result-producing functions should be easy to describe. To update your code, rename any call to `fail!` to `panic!` instead. Assuming you have not created your own macro named `panic!`, this will work on UNIX based systems: grep -lZR 'fail!' . | xargs -0 -l sed -i -e 's/fail!/panic!/g' You can of course also do this by hand.
