Removed `extmap` and added .mjs entry in `map_file_extension`.
The assert in the compiler does not need to be updated, since it is
resolving from the compiled cache instead of elsewhere (notice the .map
is asserted next to it)
sccache doesn't work for cache debug builds at the moment, because it
doesn't support the `-Xclang -fdebug-compilation-dir` flag that has been
added by the most recent V8 upgrade.
This patch should make the asan/lsan job on Travis CI fast again.
The following tests were commented out in order to get this to go green :
- bodyMultipartFormData
- bodyURLEncodedFormData
- fetchRequestInitStringBody
- netConcurrentAccept
- netListenAsyncIterator
This patch provides a work-around for an apparent V8 bug where
initializing multiple isolates concurrently leads to a crash on
Windows.
At the time of writing the cause of this crash is not exactly
understood, but it seems to be related to the V8 internal
function win64_unwindinfo::RegisterNonABICompliantCodeRange(),
which didn't exist in older versions of V8.
* In order to prevent ArrayBuffers from getting garbage collected by V8,
we used to store a v8::Persistent<ArrayBuffer> in a map. This patch
introduces a custom ArrayBuffer allocator which doesn't use Persistent
handles, but instead stores a pointer to the actual ArrayBuffer data
alongside with a reference count. Since creating Persistent handles
has quite a bit of overhead, this change significantly increases
performance. Various HTTP server benchmarks report about 5-10% more
requests per second than before.
* Previously the Persistent handle that prevented garbage collection had
to be released manually, and this wasn't always done, which was
causing memory leaks. This has been resolved by introducing a new
`PinnedBuf` type in both Rust and C++ that automatically re-enables
garbage collection when it goes out of scope.
* Zero-copy buffers are now correctly wrapped in an Option if there is a
possibility that they're not present. This clears up a correctness
issue where we were creating zero-length slices from a null pointer,
which is against the rules.
