History

Stuart Cook 9c73bcfa8d Rollup merge of #130225 - adetaylor:rename-old-receiver, r=wesleywiser Rename Receiver -> LegacyReceiver As part of the "arbitrary self types v2" project, we are going to replace the current `Receiver` trait with a new mechanism based on a new, different `Receiver` trait. This PR renames the old trait to get it out the way. Naming is hard. Options considered included: * HardCodedReceiver (because it should only be used for things in the standard library, and hence is sort-of hard coded) * LegacyReceiver * TargetLessReceiver * OldReceiver These are all bad names, but fortunately this will be temporary. Assuming the new mechanism proceeds to stabilization as intended, the legacy trait will be removed altogether. Although we expect this trait to be used only in the standard library, we suspect it may be in use elsehwere, so we're landing this change separately to identify any surprising breakages. It's known that this trait is used within the Rust for Linux project; a patch is in progress to remove their dependency. This is a part of the arbitrary self types v2 project, https://github.com/rust-lang/rfcs/pull/3519 https://github.com/rust-lang/rust/issues/44874 r? `@wesleywiser`		2024-10-24 14:19:53 +11:00

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as an legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
