2020-05-26Add a fast path for `std::thread::panicking`.Eduardo Sánchez Muñoz-1/+1
This is done by adding a global atomic variable (non-TLS) that counts how many threads are panicking. In order to check if the current thread is panicking, this variable is read and, if it is zero, no thread (including the one where `panicking` is being called) is panicking and `panicking` can return `false` immediately without needing to access TLS. If the global counter is not zero, the local counter is accessed from TLS to check if the current thread is panicking.

2019-11-29Format libstd with rustfmtDavid Tolnay-10/+16
This commit applies rustfmt with rust-lang/rust's default settings to files in src/libstd *that are not involved in any currently open PR* to minimize merge conflicts. THe list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in outstanding_files, the relevant commands were: $ find src/libstd -name '*.rs' \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ rg libstd outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libstd. To confirm no funny business: $ git checkout $THIS_COMMIT^ $ git show --pretty= --name-only $THIS_COMMIT \ | xargs rustfmt --edition=2018 --unstable-features --skip-children $ git diff $THIS_COMMIT # there should be no difference
2019-09-25std: Reduce checks for `feature = "backtrace"`Alex Crichton-3/+0
This is a stylistic change to libstd to reduce the number of checks of `feature = "backtrace"` now that we unconditionally depend on the `backtrace` crate and rely on it having an empty implementation. otherwise.

* Bump the release version to 1.25 * Bump the bootstrap compiler to the recent beta * Allow using unstable rustdoc features on beta - this fix has been applied to the beta branch but needed to go to the master branch as well.
2017-12-28Remove an unused import for cfg(not(feature = "backtrace")).Ed Schouten-2/+0
The 'mem' module is not used for this specific code. This was copy-pasted in by accident when adding RFC 1937 (? in main) support.

2017-11-08std: Remove `rand` crate and moduleAlex Crichton-1/+0
This commit removes the `rand` crate from the standard library facade as well as the `__rand` module in the standard library. Neither of these were used in any meaningful way in the standard library itself. The only need for randomness in libstd is to initialize the thread-local keys of a `HashMap`, and that unconditionally used `OsRng` defined in the standard library anyway. The cruft of the `rand` crate and the extra `rand` support in the standard library makes libstd slightly more difficult to port to new platforms, namely WebAssembly which doesn't have any randomness at all (without interfacing with JS). The purpose of this commit is to clarify and streamline randomness in libstd, focusing on how it's only required in one location, hashmap seeds. Note that the `rand` crate out of tree has almost always been a drop-in replacement for the `rand` crate in-tree, so any usage (accidental or purposeful) of the crate in-tree should switch to the `rand` crate on crates.io. This then also has the further benefit of avoiding duplication (mostly) between the two crates!
2017-08-31Update bootstrap compilerAlex Crichton-2/+0
This commit updates the bootstrap compiler and clears out a number of #[cfg(stage0)] annotations and related business
2017-07-25Switch to begin_panic againest31-1/+3
In https://github.com/rust-lang/rust/pull/42938 we made the compiler emit a call to begin_panic_new in order to pass column info to it. Now with stage0 updated (https://github.com/rust-lang/rust/pull/43320), we can safely change begin_panic and start emitting calls for it again.

2017-05-09Don't show the std frames before user code on unwinding.Yamakaky-3/+4
When `RUST_BACKTRACE=1`, remove all frames after `__rust_maybe_catch_panic`. Tested on `main`, threads, tests and benches. Cleaning of the top of the stacktrace is let to a future PR. Fixes #40201 See #41815

Rename main thread from "<main>" to "main". Fix issue #33789 We may need to discuss whether this counts as a breaking change since code may check the main thread name against "\<main\>". Discussion is in #33789

2016-05-09rustc: Implement custom panic runtimesAlex Crichton-5/+3
This commit is an implementation of [RFC 1513] which allows applications to alter the behavior of panics at compile time. A new compiler flag, `-C panic`, is added and accepts the values `unwind` or `panic`, with the default being `unwind`. This model affects how code is generated for the local crate, skipping generation of landing pads with `-C panic=abort`. [RFC 1513]: https://github.com/rust-lang/rfcs/blob/master/text/1513-less-unwinding.md Panic implementations are then provided by crates tagged with `#![panic_runtime]` and lazily required by crates with `#![needs_panic_runtime]`. The panic strategy (`-C panic` value) of the panic runtime must match the final product, and if the panic strategy is not `abort` then the entire DAG must have the same panic strategy. With the `-C panic=abort` strategy, users can expect a stable method to disable generation of landing pads, improving optimization in niche scenarios, decreasing compile time, and decreasing output binary size. With the `-C panic=unwind` strategy users can expect the existing ability to isolate failure in Rust code from the outside world. Organizationally, this commit dismantles the `sys_common::unwind` module in favor of some bits moving part of it to `libpanic_unwind` and the rest into the `panicking` module in libstd. The custom panic runtime support is pretty similar to the custom allocator support with the only major difference being how the panic runtime is injected (takes the `-C panic` flag into account).

2015-12-09std: Rename thread::catch_panic to panic::recoverAlex Crichton-2/+3
This commit is an implementation of [RFC 1236] and [RFC 1323] which rename the `thread::catch_panic` function to `panic::recover` while also replacing the `Send + 'static` bounds with a new `PanicSafe` bound.

2015-09-11std: Internalize almost all of `std::rt`Alex Crichton-0/+65
This commit does some refactoring to make almost all of the `std::rt` private. Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports.
