A quick rundown:
- added `file::{readdir, stat, mkdir, rmdir}`
- Added access-constrained versions of `FileStream`; `FileReader` and `FileWriter` respectively
- big rework in `uv::file` .. most actions are by-val-self methods on `FsRequest`; `FileDescriptor` has gone the way of the dinosaurs
- playing nice w/ homing IO (I just copied ecr's work, hehe), etc
- added `FileInfo` trait, with an impl for `Path`
- wrapper for file-specific actions, with the file path always implied by self's value
- has the means to create `FileReader` & `FileWriter` (this isn't exposed in the top-level free function API)
- has "safe" wrappers for `stat()` that won't throw in the event of non-existence/error (in this case, I mean `is_file` and `exists`)
- actions should fail if done on non-regular-files, as appropriate
- added `DirectoryInfo` trait, with an impl for `Path`
- pretty much ditto above, but for directories
- added `readdir` (!!) to iterate over entries in a dir as a `~[Path]` (this was *brutal* to get working)
...<del>and lots of other stuff</del>not really. Do your worst!
This doesn't close any bugs as the goal is to convert the parameter to by-value, but this is a step towards being able to make guarantees about `&T` pointers (where T is Freeze) to LLVM.
std: remove unneeded field from RequestData struct
std: rt::uv::file - map us_fs_stat & start refactoring calls into FsRequest
std: stubbing out stat calls from the top-down into uvio
std: us_fs_* operations are now by-val self methods on FsRequest
std: post-rebase cleanup
std: add uv_fs_mkdir|rmdir + tests & minor test cleanup in rt::uv::file
WORKING: fleshing out FileStat and FileInfo + tests
std: reverting test files..
refactoring back and cleanup...
Fix uint overflow bugs in std::{at_vec, vec, str}
Closes#8742
Fix issue #8742, which summarized is: unsafe code in vec and str did assume
that a reservation for `X + Y` elements always succeeded, and didn't overflow.
Introduce the method `Vec::reserve_additional(n)` to make it easy to check for
overflow in `Vec::push` and `Vec::push_all`.
In std::str, simplify and remove a lot of the unsafe code and use `push_str`
instead. With improvements to `.push_str` and the new function
`vec::bytes::push_bytes`, it looks like this change has either no or positive
impact on performance.
I believe there are many places still where `v.reserve(A + B)` still can overflow.
This by itself is not an issue unless followed by (unsafe) code that steps aside
boundary checks.
A SendStr is a string that can hold either a ~str or a &'static str.
This can be useful as an optimization when an allocation is sometimes needed but the common case is statically known.
Possible use cases include Maps with both static and owned keys, or propagating error messages across task boundaries.
SendStr implements most basic traits in a way that hides the fact that it is an enum; in particular things like order and equality are only determined by the content of the wrapped strings.
Replaced std::rt:logging::SendableString with SendStr
Added tests for using an SendStr as key in Hash- and Treemaps
Remove these in favor of the two traits themselves and the wrapper
function std::from_str::from_str.
Add the function std::num::from_str_radix in the corresponding role for
the FromStrRadix trait.
Work a bit towards #9157 "Remove Either". These instances don't need to use Either and are better expressed in other ways (removing allocations and simplifying types).
This is a series of patches to modernize option and result. The highlights are:
* rename `.unwrap_or_default(value)` and etc to `.unwrap_or(value)`
* add `.unwrap_or_default()` that uses the `Default` trait
* add `Default` implementations for vecs, HashMap, Option
* add `Option.and(T) -> Option<T>`, `Option.and_then(&fn() -> Option<T>) -> Option<T>`, `Option.or(T) -> Option<T>`, and `Option.or_else(&fn() -> Option<T>) -> Option<T>`
* add `option::ToOption`, `option::IntoOption`, `option::AsOption`, `result::ToResult`, `result::IntoResult`, `result::AsResult`, `either::ToEither`, and `either::IntoEither`, `either::AsEither`
* renamed `Option::chain*` and `Result::chain*` to `and_then` and `or_else` to avoid the eventual collision with `Iterator.chain`.
* Added a bunch of impls of `Default`
* Added a `#[deriving(Default)]` syntax extension
* Removed impls of `Zero` for `Option<T>` and vecs.
