Many programs do not handle non-blocking stdio very well. In particular,
man and less have serious problems with this, and since stdout isn't being
flushed after each write, the output jumps about on the screen as you page
down. Programs that do use non-blocking stdio will set that flag themselves
(as node does).
This puts the stdio file descriptors into blocking mode before sharing them
with the child process, so that one could spawn a vim subprocess, or some
other program that depends on blocking IO.
Add NODE_MODULE_CONTEXTS env var
Only one test was modified to check that this works. NEED to go through all
tests and modify them so that
NODE_MODULE_CONTEXTS=1 make test
passes.
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.
Some compile time variables like the cflags and prefix have been moved to
the node_config.h.in, in the anticipation that they will be removed at
somepoint.
