2014-06-27std::io: Use re-exported pathes in examples.OGINO Masanori-2/+2
We use re-exported pathes (e.g. std::io::Command) and original ones (e.g. std::io::process::Command) together in examples now. Using re-exported ones consistently avoids confusion. Signed-off-by: OGINO Masanori <masanori.ogino@gmail.com>
2014-06-24librustc: Remove the fallback to `int` from typechecking.Niko Matsakis-1/+1
This breaks a fair amount of code. The typical patterns are: * `for _ in range(0, 10)`: change to `for _ in range(0u, 10)`; * `println!("{}", 3)`: change to `println!("{}", 3i)`; * `[1, 2, 3].len()`: change to `[1i, 2, 3].len()`. RFC #30. Closes #6023. [breaking-change]
2014-06-16std: Support consuming a Process without waitingAlex Crichton-0/+23
Forking off a child which survives the parent is often a useful task, and is currently not possible because the Process type will invoke `wait()` in its destructor in order to prevent leaking resources. This function adds a new safe method, `forget`, which can be used to consume an instance of `Process` which will then not call `wait` in the destructor. This new method is clearly documented as a leak of resources, but it must be forcibly opted in to. Closes #14467

2014-06-01std: Drop Total from Total{Eq,Ord}Alex Crichton-2/+2
This completes the last stage of the renaming of the comparison hierarchy of traits. This change renames TotalEq to Eq and TotalOrd to Ord. In the future the new Eq/Ord will be filled out with their appropriate methods, but for now this change is purely a renaming change. [breaking-change]
2014-05-30std: Rename {Eq,Ord} to Partial{Eq,Ord}Alex Crichton-2/+2
This is part of the ongoing renaming of the equality traits. See #12517 for more details. All code using Eq/Ord will temporarily need to move to Partial{Eq,Ord} or the Total{Eq,Ord} traits. The Total traits will soon be renamed to {Eq,Ord}. cc #12517 [breaking-change]

The span on a inner doc-comment would point to the next token, e.g. the span for the `a` line points to the `b` line, and the span of `b` points to the `fn`. ```rust //! a //! b fn bar() {} ```

2014-05-15Updates with core::fmt changesAlex Crichton-2/+2
1. Wherever the `buf` field of a `Formatter` was used, the `Formatter` is used instead. 2. The usage of `write_fmt` is minimized as much as possible, the `write!` macro is preferred wherever possible. 3. Usage of `fmt::write` is minimized, favoring the `write!` macro instead.
2014-05-14Process::new etc should support non-utf8 commands/argsAaron Turon-305/+290
The existing APIs for spawning processes took strings for the command and arguments, but the underlying system may not impose utf8 encoding, so this is overly limiting. The assumption we actually want to make is just that the command and arguments are viewable as [u8] slices with no interior NULLs, i.e., as CStrings. The ToCStr trait is a handy bound for types that meet this requirement (such as &str and Path). However, since the commands and arguments are often a mixture of strings and paths, it would be inconvenient to take a slice with a single T: ToCStr bound. So this patch revamps the process creation API to instead use a builder-style interface, called `Command`, allowing arguments to be added one at a time with differing ToCStr implementations for each. The initial cut of the builder API has some drawbacks that can be addressed once issue #13851 (libstd as a facade) is closed. These are detailed as FIXMEs. Closes #11650. [breaking-change]
2014-05-13io: Implement process wait timeoutsAlex Crichton-59/+131
This implements set_timeout() for std::io::Process which will affect wait() operations on the process. This follows the same pattern as the rest of the timeouts emerging in std::io::net. The implementation was super easy for everything except libnative on unix (backwards from usual!), which required a good bit of signal handling. There's a doc comment explaining the strategy in libnative. Internally, this also required refactoring the "helper thread" implementation used by libnative to allow for an extra helper thread (not just the timer). This is a breaking change in terms of the io::Process API. It is now possible for wait() to fail, and subsequently wait_with_output(). These two functions now return IoResult<T> due to the fact that they can time out. Additionally, the wait_with_output() function has moved from taking `&mut self` to taking `self`. If a timeout occurs while waiting with output, the semantics are undesirable in almost all cases if attempting to re-wait on the process. Equivalent functionality can still be achieved by dealing with the output handles manually. [breaking-change] cc #13523

2014-05-08Handle fallout in io::net::addrinfo, io::process, and rt::rtioKevin Ballard-2/+2
API Changes: - get_host_addresses() returns IoResult<Vec<IpAddr>> - Process.extra_io is Vec<Option<io::PipeStream>>
2014-05-07core: Inherit possible string functionalityAlex Crichton-1/+0
This moves as much allocation as possible from teh std::str module into core::str. This includes essentially all non-allocating functionality, mostly iterators and slicing and such. This primarily splits the Str trait into only having the as_slice() method, adding a new StrAllocating trait to std::str which contains the relevant new allocation methods. This is a breaking change if any of the methods of "trait Str" were overriden. The old functionality can be restored by implementing both the Str and StrAllocating traits. [breaking-change]
2014-05-06librustc: Remove `~EXPR`, `~TYPE`, and `~PAT` from the language, exceptPatrick Walton-1/+2
for `~str`/`~[]`. Note that `~self` still remains, since I forgot to add support for `Box<self>` before the snapshot. How to update your code: * Instead of `~EXPR`, you should write `box EXPR`. * Instead of `~TYPE`, you should write `Box<Type>`. * Instead of `~PATTERN`, you should write `box PATTERN`.

2014-04-18std: Make ~[T] no longer a growable vectorAlex Crichton-6/+2
This removes all resizability support for ~[T] vectors in preparation of DST. The only growable vector remaining is Vec<T>. In summary, the following methods from ~[T] and various functions were removed. Each method/function has an equivalent on the Vec type in std::vec unless otherwise stated. * slice::OwnedCloneableVector * slice::OwnedEqVector * slice::append * slice::append_one * slice::build (no replacement) * slice::bytes::push_bytes * slice::from_elem * slice::from_fn * slice::with_capacity * ~[T].capacity() * ~[T].clear() * ~[T].dedup() * ~[T].extend() * ~[T].grow() * ~[T].grow_fn() * ~[T].grow_set() * ~[T].insert() * ~[T].pop() * ~[T].push() * ~[T].push_all() * ~[T].push_all_move() * ~[T].remove() * ~[T].reserve() * ~[T].reserve_additional() * ~[T].reserve_exect() * ~[T].retain() * ~[T].set_len() * ~[T].shift() * ~[T].shrink_to_fit() * ~[T].swap_remove() * ~[T].truncate() * ~[T].unshift() * ~str.clear() * ~str.set_len() * ~str.truncate() Note that no other API changes were made. Existing apis that took or returned ~[T] continue to do so. [breaking-change]

There's a little more allocation here and there now since from_utf8_owned can't be used with Vec.

2014-03-28native: Use WNOHANG before signalingAlex Crichton-3/+26
It turns out that on linux, and possibly other platforms, child processes will continue to accept signals until they have been *reaped*. This means that once the child has exited, it will succeed to receive signals until waitpid() has been invoked on it. This is unfortunate behavior, and differs from what is seen on OSX and windows. This commit changes the behavior of Process::signal() to be the same across platforms, and updates the documentation of Process::kill() to note that when signaling a foreign process it may accept signals until reaped. Implementation-wise, this invokes waitpid() with WNOHANG before each signal to the child to ensure that if the child has exited that we will reap it. Other possibilities include installing a SIGCHLD signal handler, but at this time I believe that that's too complicated. Closes #13124
2014-03-27Fix fallout of removing default boundsAlex Crichton-1/+1
This is all purely fallout of getting the previous commit to compile.
2014-03-20std: Implement Clone/TotalEq for ProcessExitAlex Crichton-1/+2
It's useful for structures which use deriving(Clone, TotalEq), even though it's implicitly copyable. Closes #13047
2014-03-13std: Rename Chan/Port types and constructorAlex Crichton-5/+5
* Chan<T> => Sender<T> * Port<T> => Receiver<T> * Chan::new() => channel() * constructor returns (Sender, Receiver) instead of (Receiver, Sender) * local variables named `port` renamed to `rx` * local variables named `chan` renamed to `tx` Closes #11765
2014-02-24windows: Fix the test_exists unit testAlex Crichton-2/+5
Turns out the `timeout` command was exiting immediately because it didn't like its output piped. Instead use `ping` repeatedly to get a process that will sleep for awhile. cc #12516
2014-02-24Correctly ignore some tests on windowsAlex Crichton-2/+1
These two tests are notoriously flaky on the windows bots right now, so I'm ignoring them until I can investigate them some more. The truncate_works test has been flaky for quite some time, but it has gotten much worse recently. The test_exists test has been flaky since the recent std::run rewrite landed. Finally, the "unix pipe" test failure is a recent discovery on the try bots. I haven't seen this failing much, but better safe than sorry! cc #12516
2014-02-23Roll std::run into std::io::processAlex Crichton-78/+519
The std::run module is a relic from a standard library long since past, and there's not much use to having two modules to execute processes with where one is slightly more convenient. This commit merges the two modules, moving lots of functionality from std::run into std::io::process and then deleting std::run. New things you can find in std::io::process are: * Process::new() now only takes prog/args * Process::configure() takes a ProcessConfig * Process::status() is the same as run::process_status * Process::output() is the same as run::process_output * I/O for spawned tasks is now defaulted to captured in pipes instead of ignored * Process::kill() was added (plus an associated green/native implementation) * Process::wait_with_output() is the same as the old finish_with_output() * destroy() is now signal_exit() * force_destroy() is now signal_kill() Closes #2625 Closes #10016
2014-02-16Allow configuration of uid/gid/detach on processesAlex Crichton-23/+106
This just copies the libuv implementation for libnative which seems reasonable enough (uid/gid fail on windows). Closes #12082

2014-01-15Issue #3511 - Rationalize temporary lifetimes.Niko Matsakis-7/+7
Major changes: - Define temporary scopes in a syntax-based way that basically defaults to the innermost statement or conditional block, except for in a `let` initializer, where we default to the innermost block. Rules are documented in the code, but not in the manual (yet). See new test run-pass/cleanup-value-scopes.rs for examples. - Refactors Datum to better define cleanup roles. - Refactor cleanup scopes to not be tied to basic blocks, permitting us to have a very large number of scopes (one per AST node). - Introduce nascent documentation in trans/doc.rs covering datums and cleanup in a more comprehensive way.
2013-12-27Bring native process bindings up to dateAlex Crichton-2/+149
Move the tests into libstd, use the `iotest!` macro to test both native and uv bindings, and use the cloexec trick to figure out when the child process fails in exec.
2013-12-24std: Expose that LocalIo may not always be availableAlex Crichton-13/+11
It is not the case that all programs will always be able to acquire an instance of the LocalIo borrow, so this commit exposes this limitation by returning Option<LocalIo> from LocalIo::borrow(). At the same time, a helper method LocalIo::maybe_raise() has been added in order to encapsulate the functionality of raising on io_error if there is on local I/O available.
