Adds a lazily created code cache to `deno compile` by default.
The code cache is created on first run to a single file in the temp
directory and is only written once. After it's been written, the code
cache becomes read only on subsequent runs. Only the modules loaded
during startup are cached (dynamic imports are not code cached).
The code cache can be disabled by compiling with `--no-code-cache`.
This commit deprecates "import assertions" proposal that has been
replaced with "import attributes".
Any time an import assertion is encountered a warning will be printed
to the terminal. This warning will be printed for both local and
remote files (ie. user code and dependencies).
Import assertions support will be removed in Deno 2.
In https://github.com/denoland/deno/pull/23955 we changed the sqlite db
journal mode to WAL. This causes issues when someone is running an old
version of Deno using TRUNCATE and a new version because the two fight
against each other.
This PR enables V8 code cache for ES modules and for `require` scripts
through `op_eval_context`. Code cache artifacts are transparently stored
and fetched using sqlite db and are passed to V8. `--no-code-cache` can
be used to disable.
