It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh
the potential stability issues and intrusive changes to the code base that
first-class support for isolates requires.
Hence, this commit backs out all isolates-related changes.
Good bye, isolates. We hardly knew ye.
defines cannot be used if the callback is a templated and has
multiple template arguments. The comma separating the arguments
breaks the preprocessor argument handling. Using a templated function
is clearer and more idiomatic in c++.
For greater flexibility in controlling node's initialization and startup, the
following new functions are exported.
- node::Init()
- node::SetupProcessObject()
- node::Load()
- node::EmitExit()
These are some of the major steps involved in node::Setup(). Exporting these
functions allows an embedding program to write a replacement for node::Start(),
and to have access to the node process object after it's created.
Set the stage for making the builtin modules more dynamic.
Note: this only converts crypto and net, I will add more extensions in a
later commit.
* node.h: Add utility macro for converting macro values to strings.
* node.h: Include the actual module name inside the module structure, not
just the file it was built from.
* node.h: New Macro, NODE_MODULE_DECL, for declaring an external reference
to a module structure.
* node_extensions.cc: New File, implements get_builtin_module, which
iterates over the module structures that are compiled into node.
* node.cc(node::Binding): Use the new module lookup function to find
modules.
* node_{net,crypto}.c: Add NODE_MODULEs to generate the module structure.
