bors 8c52a83c45 Auto merge of #98570 - SparrowLii:deadlock, r=cjgillot ... get rid of `tcx` in deadlock handler when parallel compilation This is a very obscure and hard-to-trace problem that affects thread scheduling. If we copy `tcx` to the deadlock handler thread, it will perform unpredictable behavior and cause very weird problems when executing `try_collect_active_jobs`(For example, the deadlock handler thread suddenly preempts the content of the blocked worker thread and executes the unknown judgment branch, like #94654). Fortunately we can avoid this behavior by precomputing `query_map`. This change fixes the following ui tests failure on my environment when set `parallel-compiler = true`: ``` [ui] src/test\ui\async-await\no-const-async.rs [ui] src/test\ui\infinite\infinite-struct.rs [ui] src/test\ui\infinite\infinite-tag-type-recursion.rs [ui] src/test\ui\issues\issue-3008-1.rs [ui] src/test\ui\issues\issue-3008-2.rs [ui] src/test\ui\issues\issue-32326.rs [ui] src/test\ui\issues\issue-57271.rs [ui] src/test\ui\issues\issue-72554.rs [ui] src/test\ui\parser\fn-header-semantic-fail.rs [ui] src/test\ui\union\union-nonrepresentable.rs ``` Updates #75760 Fixes #94654		2022-07-03 02:05:14 +00:00
