When we migrated away from all the locks, there was a regression that
was not caught immediately. The tsc::get_asset() would attempt to modify
the snapshot, but the problem was that the snapshot was a .clone() of
the inner language server's assets, which meant that modifications to
that where lost. When we then attempted to do a hover on those assets,
the inner language servers assets didn't have the retrieved asset, and
therefore would throw an error.
Commit 2828690fc ("fix(lsp): fix deadlocks, use one big mutex") from
last month introduced a regression in asset cache lookups where results
of lazy caching were lost due to operating on a copy of the asset cache.
This commit fixes that by copying the asset from the copy to the real
cache.
The mutex was used to hide the fact that the Sources object mutates
itself when it's queried. Be honest about that and mark everything that
directly or indirectly mutates it as `mut`.
This is a follow-up to commit 2828690fc7
from last month ("fix(lsp): fix deadlocks, use one big mutex (#9271)")
Include the lower-level error message in the generic error message.
No test because I can't actually make it fail by passing it bad PEM.
I checked and `reqwest::Certificate::from_pem()` always returns `Ok()`.
Fixes #9364.
This removes the std folder from the tree.
Various parts of the tests are pretty tightly dependent
on std (47 direct imports and 75 indirect imports, not
counting the cli tests that use them as fixtures) so I've
added std as a submodule for now.
This commit reorganises cli/tests/integration_tests.rs.
All integration tests had been moved into integration module,
which allows to run only integration tests by "cargo test integration".
Additionally some tests were further grouped under nested modules
like "inspector", "file_watcher" or "repl".
This commits makes use of source maps and the original source
when printing lacking line coverage in the pretty printer.
Only the executable lines are checked as before (as non-executable
lines will always be ignored anyways). The lines then mapped to the
appropriate source line when a source map is present.
The LSP code had numerous places where competing threads could take out
out locks in different orders, making it very prone to deadlocks.
This commit sidesteps the entire issue by switching to a single lock.
The above is a little white lie: the Sources struct still uses a mutex
internally to avoid having to boil the ocean (because being honest about
what it does involves changing all its methods to `&mut self` but that
ripples out extensively...) I'll save that one for another day.
