RandomBytes() allocated memory with new[] which was then handed off to
Buffer::Use() which eventually releases it again with free().
Mixing the two is technically a violation of the spec and besides, it's
generally frowned upon.
Achieve a minor speed-up by looking up the timeout callback on the timer
object by using an array index rather than a named property.
Gives a performance boost of about 1% on the misc/timers benchmarks.
Code cleanup: don't call a Connection object `p` in some places, `c` in
other places and `ss` in yet other places. Let's just call it `conn`.
This also fixes about a million style errors in one fell swoop.
Don't create an Integer when setting a numeric index on an object or an
array, use the version of v8::Object::Set() that takes an uint32_t.
Change the types of the variables from int to uint32_t and clean up
some code consistency issues while we're here.
Don't set the oncomplete property in src/cares_wrap.cc, we can do it
just as easily in lib/dns.js.
Switch two closures to the 'function with _this_ object' model. Makes
it impossible for an overzealous closure to capture too much context
and accidentally hold on to too much memory.
Use v8::Integer::NewFromUnsigned() when updating the writeQueueSize
field.
Before this commit, it used v8::Integer::New() but that takes an
int32_t. It's unlikely for a write queue to grow beyond 2**31-1 bytes
but let's use the unsigned integer constructor anyway, just in case.
Change process.domain to use a getter/setter and access that property
via an array index. These are much faster to get from c++, and it can be
passed to _setupDomainUse and stored as a Persistent<Array>.
InDomain() and GetDomain() as trivial ways to access the domain
information in the native layer. Important because we'll be able to
quickly access if a domain is active. Instead of just whether the domain
module has been loaded.
Don't use v8::Object::SetHiddenValue() to keep a reference alive to the
buffer, we can just as easily do that from JS land and it's a lot faster
to boot.
Because the buffer is now a visible property of the write request
object, it's essential that we do *not* log it - we'd be effectively
serializing the whole buffer to a pretty-printed string.
* Change calls to String::New() and String::NewSymbol() to their
respective one-byte, two-byte and UTF-8 counterparts.
* Add a FIXED_ONE_BYTE_STRING macro that takes a string literal and
turns it into a v8::Local<v8::String>.
* Add helper functions that make v8::String::NewFromOneByte() easier to
work with. Said function expects a `const uint8_t*` but almost every
call site deals with `const char*` or `const unsigned char*`. Helps
us avoid doing reinterpret_casts all over the place.
* Code that handles file system paths keeps using UTF-8 for backwards
compatibility reasons. At least now the use of UTF-8 is explicit.
* Remove v8::String::NewSymbol() entirely. Almost all call sites were
effectively minor de-optimizations. If you create a string only once,
there is no point in making it a symbol. If you are create the same
string repeatedly, it should probably be cached in a persistent
handle.
smalloc.alloc now accepts an optional third argument which allows
specifying the type of array that should be allocated. All available
types are now located on smalloc.Types.
* Moved the ToObject check out of smalloc::Alloc and into JS. Direct
usage of that method is for internal use only and so can bypass the
possible coercion.
* Same has been done with smalloc::SliceOnto.
* smalloc::CopyOnto will now throw if passed argument is not an object.
* Remove extra TargetFreeCallback function. There was a use for it when
it was working with a Local<T>, but that code has been removed making
the function superfluous.
Add is_named_pipe(), is_named_pipe_ipc() and is_tcp() and update the
code base to use those rather than `stream->type == UV_FOO` and
`reinterpret_cast<uv_pipe_t*>(handle)->ipc` style checks.
Hide member fields behind getters. Make the fields themselves const
in the sense that the pointer is non-assignable - the pointed to object
remains mutable.
Makes reasoning about lifecycle and mutability a little easier.
Don't create a superfluous Number object, just use the version of
v8::Object::Get() that takes an unsigned int. Convert the index to
unsigned int while we're here.
The type of the expression `(uint16_t) server_names_len + 2` gets
implicitly widened to int. Change the type of server_names_len to
uint32_t to avoid the following warnings:
../../src/node_crypto_clienthello.cc:144: warning: comparison
between signed and unsigned integer expressions
../../src/node_crypto_clienthello.cc:146: warning: comparison
between signed and unsigned integer expressions
Update a few more `Local<T>::New(isolate, persistent)` call sites to
`PersistentToLocal(isolate, persistent)` - the latter has a fast path
for non-weak persistent references.
When doing `FreeEmpty`, `NodeBIO` skips pre-allocated `head_` buffer.
However this might lead to double-freeing buffers since in `~NodeBIO()`
we're starting deallocation from `head_` buffer.
Commit 78d9094 updated src/*.cc to use the version of PersistentToLocal
that takes a v8::Isolate* as its first argument. This commit removes
the non-isolate version.
