Using Thrift with Haxe
========================
Haxe setup
---------------
Thrift requires Haxe 4.2.1. Installers for Windows and OSX
platforms are available at `http://haxe.org/download`.
Depending on the desired targets, you may have to install the appropriate HaxeLibs
after installing Haxe itself. For example, if you plan to target C++, enter the
following command after installing Haxe:
haxelib install hxcpp
For other targets, please consult the Haxe documentation whether or not any additional
target libraries need to be installed and how to achieve this.
Haxe on Linux
---------------
For Linux platforms it is recommended to use the distro-specific package
manager, where possible. More detailed information can be found at the
Haxe Linux download section: http://haxe.org/download/linux
If you run into the error message
Uncaught exception - load.c(237) : Failed to load library : /usr/lib/neko/regexp.ndll
(libpcre.so.3: cannot open shared object file: No such file or directory)
this can be solved depending on your OSes bitness by either
sudo ln -sf /usr/lib/libpcre.so.1 /usr/lib/libpcre.so.3
sudo ldconfig
or
sudo ln -sf /usr/lib64/libpcre.so.1 /usr/lib64/libpcre.so.3
sudo ldconfig
Thrift Haxe bindings
-------------------
Thrift Haxe bindings can be set up via the `haxelib` tool as usual.
Alternatively, the "github" method can be used.
- To set up any **stable version**, choose the appropriate branch (e.g. `0.14.1`):
- `haxelib git thrift https://github.com/apache/thrift.git 0.14.1 lib/haxe`
- To set up the current **development version**, use the `master` branch:
- `haxelib git thrift https://github.com/apache/thrift.git master lib/haxe`
As usual, the installed library can be updated using `haxelib upgrade`
or `haxelib update thrift`.
In order to work with Thrift, you will need to install the Thrift compiler
or build from source, depending on your operating system. Appropriate
downloads and more information can be found at http://thrift.apache.org
To get started, visit the /tutorial/haxe and /test/haxe dirs for examples.
If you are using the HaxeDevelop IDE, you'll find appropriate project files
in these folders.
Breaking changes
========================
This version requires Haxe 4 and cannot be used with earlier versions.
It is recommended to clear out all gen-haxe contents once before switching
to the new version. Otherwise you may run into troubles with leftovers from
previous versions.
The compiler option ```callbacks``` is now obsolete. The compiler will always
generate a dual interface (i.e. with optional callback style) for use on the
client side, plus a new ```_service``` interface to be used for server
implementations. Consequentially, your client and server implementations will
need some manual intervention.
PHP HTTP Server notes
========================
- you have to import PHP files generated by haxe into PHP
```php
require_once dirname(__FILE__) . '/bin/php-web-server/Main-debug.php';
```
- trace() by default outputs into stdout (http response), so you have to redirect it to stderr or you own logs, something like
```haxe
//remap trace to error log
haxe.Log.trace = function(v:Dynamic, ?infos:haxe.PosInfos)
{
//simulate normal trace https://github.com/HaxeFoundation/haxe/blob/development/std/haxe/Log.hx
var newValue : Dynamic;
if (infos != null && infos.customParams!=null) {
var extra:String = "";
for( v in infos.customParams )
extra += "," + v;
newValue = v + extra;
}
else {
newValue = v;
}
var msg = infos != null ? infos.fileName + ':' + infos.lineNumber + ': ' : '';
Sys.stderr().writeString('${msg}${newValue}\n');
}
```
- to allow thrift server to read/write HTTP request/response, it should be pointed out to php streams
```haxe
transport = new TWrappingServerTransport(
new TStreamTransport(
new TFileStream("php://input", Read),
new TFileStream("php://output", Append)
)
);
```
- TSimpleServer doesn't stop after first call, so processor.process() should be called instead, or use runOnce property
```haxe
var server = new TSimpleServer( processor, transport, transfactory, protfactory);
server.runOnce = true;
```
