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.
* The test calls an internal API that changed in commit ca9eb71.
* Trying to reverse-lookup a bogus hostname now returns EINVAL rather
than the (bogus!) status code ENOTIMP.
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.
This is [1] applied ahead of time. Summary:
OpenBSD doesn't have <ucontext.h>. ucontext_t lives in <signal.h>
and is a typedef for struct sigcontext. There is no uc_mcontext.

Note: the patch has been accepted upstream but hasn't made its way into
a stable release yet.
No one in this day and age should be using SSLv2 so disable it by
default. You can re-enable it with `./configure --with-sslv2` but
there really should be no reason for that.
Alphabetical order should make it easier to find the switches you need
because we've got quite a lot of them now.
Keep --prefix at the top because that's arguably the one people will be
looking for most.
Don't run configure when the configure script has been touched. Doing so
would be okay if the Makefile passed the original arguments to configure
but it doesn't - it runs configure without any arguments, effectively
destroying the current configuration.
Remove this misfeature and instead print an error message telling the
user to (re-)run configure.
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.
v0.10 allows strings for the offset, length and port arguments to
dgram.send() and dgram.sendto() but master before this commit would
abort with the following assert:
node: ../../src/udp_wrap.cc:227: static void
node::UDPWrap::DoSend(const v8::FunctionCallbackInfo<v8::Value>&,
int): Assertion `args[2]->IsUint32()' failed.
Go beyond what v0.10 does and also add range checks: offset and length
should be >= 0, port should be between 1 and 65535.
That particular change needs to be back-ported to v0.10 because passing
a negative offset or length number aborts with the following assertions:
node: ../../src/udp_wrap.cc:264: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`offset < Buffer::Length(buffer_obj)' failed.
Or:
node: ../../src/udp_wrap.cc:265: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`length <= Buffer::Length(buffer_obj) - offset' failed.
Interestingly enough, a negative port number is accepted in v0.10 but
is silently ignored.
This commit exposed a bug in the simple/test-dgram-close test which
has also been fixed.
* 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.
When a stream is flowing, and not in the middle of a sync read, and
the read buffer currently has a length of 0, we can just emit a 'data'
event rather than push it onto the array, emit 'readable', and then
automatically call read().
As it happens, this is quite a frequent occurrence! Making this change
brings the HTTP benchmarks back into a good place after the removal of
the .ondata/.onend socket kludge methods.
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.
There are some agent subclasses using this today.
Despite the addRequest function being undocumented internal API, it's
easy enough to just support the old signature for backwards
compatibility.
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.
