The two main goals of this change are:
- To make it easier to build the Intl option using ICU (particularly,
using a newer ICU than v8/Chromium's version)
- To enable a much smaller ICU build with only English support The goal
here is to get node.js binaries built this way by default so that the
Intl API can be used. Additional data can be added at execution time
(see Readme and wiki)
More details are at https://github.com/joyent/node/pull/7719
In particular, this change adds the "--with-intl=" configure option to
provide more ways of building "Intl":
- "full-icu" picks up an ICU from deps/icu
- "small-icu" is similar, but builds only English
- "system-icu" uses pkg-config to find an installed ICU
- "none" does nothing (no Intl)
For Windows builds, the "full-icu" or "small-icu" options are added to
vcbuild.bat.
Note that the existing "--with-icu-path" option is not removed from
configure, but may not be used alongside the new option.
Wiki changes have already been made on
https://github.com/joyent/node/wiki/Installation
and a new page created at
https://github.com/joyent/node/wiki/Intl
(marked as provisional until this change lands.)
Summary of changes:
* README.md : doc updates
* .gitignore : added "deps/icu" as this is the location where ICU is
unpacked to.
* Makefile : added the tools/icu/* files to cpplint, but excluded a
problematic file.
* configure : added the "--with-intl" option mentioned above.
Calculate at config time the list of ICU source files to use and data
packaging options.
* node.gyp : add the new files src/node_i18n.cc/.h as well as ICU
linkage.
* src/node.cc : add call into
node::i18n::InitializeICUDirectory(icu_data_dir) as well as new
--icu-data-dir option and NODE_ICU_DATA env variable to configure ICU
data loading. This loading is only relevant in the "small"
configuration.
* src/node_i18n.cc : new source file for the above Initialize..
function, to setup ICU as needed.
* tools/icu : new directory with some tools needed for this build.
* tools/icu/icu-generic.gyp : new .gyp file that builds ICU in some new
ways, both on unix/mac and windows.
* tools/icu/icu-system.gyp : new .gyp file to build node against a
pkg-config detected ICU.
* tools/icu/icu_small.json : new config file for the "English-only" small
build.
* tools/icu/icutrim.py : new tool for trimming down ICU data. Reads the
above .json file.
* tools/icu/iculslocs.cc : new tool for repairing ICU data manifests
after trim operation.
* tools/icu/no-op.cc : dummy file to force .gyp into using a C++ linker.
* vcbuild.bat : added small-icu and full-icu options, to call into
configure.
* Fixed toolset dependencies, see
https://github.com/joyent/node/pull/7719#issuecomment-54641687
Note that because of a bug in gyp {CC,CXX}_host must also be set.
Otherwise gcc/g++ will be used by default for part of the build.

fix #7249
Turn off -Werror when building V8, it hits -Werror=unused-local-typedefs
with g++ 4.8. The warning itself is harmless so don't abort the build.
This was originally implemented in commit d2ab314e back in 2011 but the
build process has gone through a few iterations since then, that change
no longer works.
Add a new 'tracing' module with a v8 property that lets the user
register listeners for gc events. The listeners are invoked after
every garbage collection cycle with 'before' and 'after' statistics.
Useful for monitoring tools that want to keep track of memory usage.
Built-in modules should be automatically registered, replacing the
static module list. Add-on modules should also be automatically
registered via DSO constructors. This improves flexibility in adding
built-in modules and is also a prerequisite to pure-C addon modules.
Forcibly disable -Werror, the old { 'werror': '' } hack in node.gyp
no longer works with newer versions of V8.
We support a wide range of compilers, it's simply not feasible to
squelch all warnings, never mind that the libraries in deps/ are
not under our control.
Fixes #6817.
Previously we were building the symbols, but the linker was garbage
collecting the symbols because they weren't used. Inform the linker
that we want to keep all symbols from v8 around.
BaseObject is a class that just handles the Persistent handle attached
to the class instance.
This also removed WeakObject. Reordering the inheritance chain helps
prevent unneeded calls on instances that don't call MakeCallback.
AsyncListener is a JS API that works in tandem with the AsyncWrap class
to allow the user to be alerted to key events in the life cycle of an
asynchronous event. The AsyncWrap class has its own MakeCallback
implementation that core will be migrated to use, and uses state sharing
techniques to allow quicker communication between JS and C++ whether the
async event callbacks need to be called.
Profiling suggested that on Linux sometimes over 10% of CPU time was
being spent inside the systemtap probe entry points in the binding
layer, even when the process was not actively being traced with the
`stap` tool.
That's why this commit makes it possible to use the *_ENABLED() macros
and bail out early when we're not being traced, reducing the overhead
of unused probes to (almost) zero.
Said macros were already being generated by `dtrace -h` but were not
usable because they rely on external definitions. To remedy that, we
now generate the accompanying object files with `dtrace -G`.
This commit includes a change to libuv that has been landed upstream in
commit joyent/libuv@3c172ea.
Drop the ObjectWrap dependency in favor of an internal WeakObject class.
Let's us stop worrying about API and ABI compatibility when making
changes to the way node.js deals with weakly persistent handles
internally.
This commit makes it possible to use multiple V8 execution contexts
within a single event loop. Put another way, handle and request wrap
objects now "remember" the context they belong to and switch back to
that context when the time comes to call into JS land.
This could have been done in a quick and hacky way by calling
v8::Object::GetCreationContext() on the wrap object right before
making a callback but that leaves a fairly wide margin for bugs.
Instead, we make the context explicit through a new Environment class
that encapsulates everything (or almost everything) that belongs to
the context. Variables that used to be a static or a global are now
members of the aforementioned class. An additional benefit is that
this approach should make it relatively straightforward to add full
isolate support in due course.
There is no JavaScript API yet but that will be added in the near
future.

As documented in #3042 and in [1], the existing vm implementation has
many problems. All of these are solved by @brianmcd's [contextify][2]
package. This commit uses contextify as a conceptual base and its code
core to overhaul the vm module and fix its many edge cases and caveats.
Functionally, this fixes #3042. In particular:
- A context is now indistinguishable from the object it is based on
(the "sandbox"). A context is simply a sandbox that has been marked
by the vm module, via `vm.createContext`, with special internal
information that allows scripts to be run inside of it.
- Consequently, items added to the context from anywhere are
immediately visible to all code that can access that context, both
inside and outside the virtual machine.
This commit also smooths over the API very slightly:
- Parameter defaults are now uniformly triggered via `undefined`, per
ES6 semantics and previous discussion at [3].
- Several undocumented and problematic features have been removed, e.g.
the conflation of `vm.Script` with `vm` itself, and the fact that
`Script` instances also had all static `vm` methods. The API is now
exactly as documented (although arguably the existence of the
`vm.Script` export is not yet documented, just the `Script` class
itself).
In terms of implementation, this replaces node_script.cc with
node_contextify.cc, which is derived originally from [4] (see [5]) but
has since undergone extensive modifications and iterations to expose
the most useful C++ API and use the coding conventions and utilities of
Node core.
The bindings exposed by `process.binding('contextify')`
(node_contextify.cc) replace those formerly exposed by
`process.binding('evals')` (node_script.cc). They are:
- ContextifyScript(code, [filename]), with methods:
- runInThisContext()
- runInContext(sandbox, [timeout])
- makeContext(sandbox)
From this, the vm.js file builds the entire documented vm module API.
node.js and module.js were modified to use this new native binding, or
the vm module itself where possible. This introduces an extra line or
two into the stack traces of module compilation (and thus into most
stack traces), explaining the changed tests.
The tests were also updated slightly, with all vm-related simple tests
consolidated as test/simple/test-vm-* (some of them were formerly
test/simple/test-script-*). At the same time they switched from
`common.debug` to `console.error` and were updated to use
`assert.throws` instead of rolling their own error-testing methods.
New tests were also added, of course, demonstrating the new
capabilities and fixes.

V8 3.20.9 enforces that external pointers are aligned on a two-byte
boundary.
We cannot portably guarantee that for the source code strings that
tools/js2c.py generates so simply stop using String::NewExternal()
altogether (and by extension String::ExternalAsciiStringResource).
Fixes the following run-time assert:
FATAL ERROR: v8::String::NewExternal() Pointer is not aligned
This incarnation of macros.py is only used to disable the (d)trace
macros. Rename it so it better reflects its purpose. A new macros.py
will be added in a follow-up commit.
It will be confusing if later on we add Buffer#dispose(), and smalloc is
its own cpp api anyways. So instead create a new require('smalloc') to
expose the previous Buffer.alloc/dispose methods, and expose copyOnto
and kMaxLength as well.
Other changes:
* Added documentation and additional tests.
* smalloc::CopyOnto has changed from using assert() to throwing errors
on bad argument values because it is not exposed to the user.
* Minor style fixes.
This is a big commit that touches just about every file in the src/
directory. The V8 API has changed in significant ways. The most
important changes are:
* Binding functions take a const v8::FunctionCallbackInfo<T>& argument
rather than a const v8::Arguments& argument.
* Binding functions return void rather than v8::Handle<v8::Value>. The
return value is returned with the args.GetReturnValue().Set() family
of functions.
* v8::Persistent<T> no longer derives from v8::Handle<T> and no longer
allows you to directly dereference the object that the persistent
handle points to. This means that the common pattern of caching
oft-used JS values in a persistent handle no longer quite works,
you first need to reconstruct a v8::Local<T> from the persistent
handle with the Local<T>::New(isolate, persistent) factory method.
A handful of (internal) convenience classes and functions have been
added to make dealing with the new API a little easier.
The most visible one is node::Cached<T>, which wraps a v8::Persistent<T>
with some template sugar. It can hold arbitrary types but so far it's
exclusively used for v8::Strings (which was by far the most commonly
cached handle type.)
