2015-01-05Make temporary directory names non-deterministic.Laurence Tratt-30/+44
The previous scheme made it possible for another user/attacker to cause the temporary directory creation scheme to panic. All you needed to know was the pid of the process you wanted to target ('other_pid') and the suffix it was using (let's pretend it's 'sfx') and then code such as this would, in essence, DOS it: for i in range(0u, 1001) { let tp = &Path::new(format!("/tmp/rs-{}-{}-sfx", other_pid, i)); match fs::mkdir(tp, io::USER_RWX) { _ => () } } Since the scheme retried only 1000 times to create a temporary directory before dying, the next time the attacked process called TempDir::new("sfx") after that would typically cause a panic. Of course, you don't necessarily need an attacker to cause such a DOS: creating 1000 temporary directories without closing any of the previous would be enough to DOS yourself. This patch broadly follows the OpenBSD implementation of mkstemp. It uses the operating system's random number generator to produce random directory names that are impractical to guess (and, just in case someone manages to do that, it retries creating the directory for a long time before giving up; OpenBSD retries INT_MAX times, although 1<<31 seems enough to thwart even the most patient attacker). As a small additional change, this patch also makes the argument that TempDir::new takes a prefix rather than a suffix. This is because 1) it more closely matches what mkstemp and friends do 2) if you're going to have a deterministic part of a filename, you really want it at the beginning so that shell completion is useful.

2015-01-05auto merge of #20395 : huonw/rust/char-stab-2, r=aturonbors-5/+4
cc #19260 The casing transformations are left unstable (it is highly likely to be better to adopt the proper non-1-to-1 case mappings, per #20333) as are `is_xid_*`. I've got a little todo list in the last commit of things I thought about/was told about that I haven't yet handled (I'd also like some feedback).
2015-01-05Merge `UnicodeChar` and `CharExt`.Huon Wilson-4/+3
This "reexports" all the functionality of `core::char::CharExt` as methods on `unicode::u_char::UnicodeChar` (renamed to `CharExt`). Imports may need to be updated (one now just imports `unicode::CharExt`, or `std::char::CharExt` rather than two traits from either), so this is a [breaking-change]

2015-01-03Remove deprecated functionalityAlex Crichton-1027/+242
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.

closes #20486 closes #20474 closes #20441 [breaking-change] The `Index[Mut]` traits now have one less input parameter, as the return type of the indexing operation is an associated type. This breaks all existing implementations. --- binop traits (`Add`, `Sub`, etc) now have an associated type for their return type. Also, the RHS input parameter now defaults to `Self` (except for the `Shl` and `Shr` traits). For example, the `Add` trait now looks like this: ``` rust trait Add<Rhs=Self> { type Output; fn add(self, Rhs) -> Self::Output; } ``` The `Neg` and `Not` traits now also have an associated type for their return type. This breaks all existing implementations of these traits. --- Affected traits: - `Iterator { type Item }` - `IteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods - `DoubleEndedIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods - `DoubleEndedIteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods - `RandomAccessIterator` no input/output types - `ExactSizeIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods This breaks all the implementations of these traits.

2015-01-03Improve `make_hash` functionAndrea Canciani-8/+6
The `make_hash` function is used to prevent hashes of non-empty buckets to collide with `EMPTY_HASH = 0u64`. Ideally this function also preserve the uniform distribution of hashes and is cheap to compute. The new implementation reduces the input hash size by one bit, simply by setting the most significant bit. This obviously prevent output hashes to collide with `EMPTY_HASH` and guarantees that the uniform distribution is preserved. Moreover, the new function is simpler (no comparisons, just an OR) and (under the same assumptions as the old function, i.e. only the least significant bit will contribute to the bucket index) no additional collisions are caused.
2015-01-03auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, ↵bors-6/+6
r=nikomatsakis This modifies `Parser::eat_lt` to always split up `<<`s, instead of doing so only when a lifetime name followed or the `force` parameter (now removed) was `true`. This is because `Foo<<TYPE` is now a valid start to a type, whereas previously only `Foo<<LIFETIME` was valid. This is a [breaking-change]. Change code that looks like this: ```rust let x = foo as bar << 13; ``` to use parentheses, like this: ```rust let x = (foo as bar) << 13; ``` Closes #17362.
