Try to write the panic message with a single `write_all` call
2024-03-15 19:09:24 +01:00
Print thread ID in panic message if thread name is unknown `panic!` does not print any identifying information for threads that are unnamed. However, in many cases, the thread ID can be determined. This changes the panic message from something like this: thread '<unnamed>' panicked at src/main.rs:3:5: explicit panic To something like this: thread '<unnamed>' (0xff9bf) panicked at src/main.rs:3:5: explicit panic Stack overflow messages are updated as well. This change applies to both named and unnamed threads. The ID printed is the OS integer thread ID rather than the Rust thread ID, which should also be what debuggers print.

thread 'main' ($TID) panicked at $DIR/assert-long-condition.rs:7:5:
Don't `escape_debug` the condition of `assert!`. The assertion in `assert-long-condition.rs` used to be fail like this, all on one line: ``` thread 'main' panicked at 'assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18\n + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0', tests/ui/macros/assert-long-condition.rs:7:5 ``` The `\n` and subsequent indent is because the condition is pretty-printed, and the pretty-printer inserts a newline. Printing the newline in this way is arguably reasonable given that the message appears within single quotes, which is very similar to a string literal. However, after the assertion printing improvements that were released in 1.73, the assertion now fails like this: ``` thread 'main' panicked at tests/ui/macros/assert-long-condition.rs:7:5: assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18\n + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0 ``` Now that there are no single quotes around the pretty-printed condition, the `\n` is quite strange. This commit gets rid of the `\n`, by removing the `escape_debug` done on the pretty-printed message. This results in the following: ``` thread 'main' panicked at tests/ui/macros/assert-long-condition.rs:7:5: assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0 ``` The overly-large indent is still strange, but that's a separate pretty-printing issue. This change helps with #108341.

assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18
+ 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0
Add a ui test with an assertion that has a really long condition. The `\n` in the output is a little surprising. The next commit will deal with it.
