* restrict casting for closure.
This commit forbid casting a closure to anything other than another
closure. use rawEnv/rawProc to access underlaying pointers.
* better error message for closure cast
* fixes#5742
* proper indentation for the generated JS code
* improved dead-code elimination for JavaScript
* test the JS dead-code elimination
A new test spec has been added - "maxcodesize". It specifies the
maximum size of the generated code in bytes.
* fix right shift c codegen bug.
signed int must first be cast as unsigned before converting to larger
integer. The C compiler will auto convert operands to the largest type.
* strVal assingnable comment statement ast nodes
* Set comment instead of strVal for comment nodes
* Added test code for creating and setting comment nodes
* Modified the AST spec documentation for documentation comments
* Implement dial, support IPv6 in httpclient
Added ``dial`` procedure to networking modules: ``net``, ``asyncdispatch``,
``asyncnet``. It merges socket creation, address resolution, and connection
into single step. When using ``dial``, you don't have to worry about
IPv4 vs IPv6 problem.
Fixed addrInfo loop in connect to behave properly.
Previously it would stop on first non-immediate failure, instead of
continuing and trying the remaining addresses.
Fixed newAsyncNativeSocket to raise proper error if socket creation
fails.
Fixes: #3811
* Check domain during connect() only on non-Windows
This is how it was in the previous implementation of connect().
* Call 'osLastError' before 'close' in net.dial
* Record osLastError before freeAddrInfo in net.dial
* Add missing docs for 'dial' proc
* Optimize dial to create one FD per domain, add tests
And make async IPv6 servers work on Windows.
* Add IPv6 test to uri module
* Fix getAddrString error handling
