Updated to remove the |
@anonrig @nodejs/loaders @nodejs/cpp-reviewers can I get some reviews please? |
It seems the clang-format errors were caused by what was fixed by #54994 - not sure why it is still faililng, it could be a GitHub action hiccup? |
This works better in terms of avoiding race conditions.
This implements an API for users to intentionally flush the accumulated compile cache instead of waiting until process shutdown. It may be useful for application that loads dependencies first and then either reload itself in other instances, or spawning other instances that load an overlapping set of its dependencies - in this case its useful to flush the cache early instead of waiting until the shutdown of itself. Currently flushing is triggered by either process shutdown or user requests. In the future we should simply start the writes right after module loading on a separate thread, and this method only blocks until all the pending writes (if any) on the other thread are finished. In that case, the off-thread writes should finish long before any attempt of flushing is made so the method would then only incur a negligible overhead from thread synchronization.

For posterity: the short summary of this small diff that accidentally get landed in this unrelated PR is that it speeds up core startup by not having to compile any inner functions in essential builtins. Previously, only the top-level functions were cached in the snapshot, so during bootstrap, when the inner functions were executed to do the loading, they still needed to be compiled without cache. This diff changed to cache the inner functions too, which adds ~630KB to the binary, in exchange of a slightly faster core startup (and also speeding up the first invocation of most functions provided by the essential builtins).

module: write compile cache to temporary file and then rename it
This works better in terms of avoiding race conditions.
Drive-by: throw instead of abort when module.enableCompileCache()
gets passed a non-string argument.
module: implement flushCompileCache()
This implements an API for users to intentionally flush the
accumulated compile cache instead of waiting until process
shutdown. It may be useful for application that loads dependencies
first and then either reload itself in other instances, or spawning
other instances that load an overlapping set of its dependencies -
in this case its useful to flush the cache early instead of waiting
until the shutdown of itself.
Currently flushing is triggered by either process
shutdown or user requests. In the future we should simply start the
writes right after module loading on a separate thread, and this method
only blocks until all the pending writes (if any) on the other thread
are finished. In that case, the off-thread writes should finish long
before any attempt of flushing is made so the method would then only
incur a negligible overhead from thread synchronization.
