| <h1 id="using-thrift-with-perl">Using Thrift with Perl</h1> |
| |
| <p>Thrift requires Perl >= 5.10.0</p> |
| |
| <p>Unexpected exceptions in a service handler are converted to |
| TApplicationException with type INTERNAL ERROR and the string |
| of the exception is delivered as the message.</p> |
| |
| <p>On the client side, exceptions are thrown with die, so be sure |
| to wrap eval{} statments around any code that contains exceptions.</p> |
| |
| <p>Please see tutoral and test dirs for examples.</p> |
| |
| <p>The Perl ForkingServer ignores SIGCHLD allowing the forks to be |
| reaped by the operating system naturally when they exit. This means |
| one cannot use a custom SIGCHLD handler in the consuming perl |
| implementation that calls serve(). It is acceptable to use |
| a custom SIGCHLD handler within a thrift handler implementation |
| as the ForkingServer resets the forked child process to use |
| default signal handling.</p> |
| |
| <h1 id="dependencies">Dependencies</h1> |
| |
| <p>The following modules are not provided by Perl 5.10.0 but are required |
| to use Thrift.</p> |
| |
| <h2 id="runtime">Runtime</h2> |
| |
| <ul> |
| <li>Bit::Vector</li> |
| <li>Class::Accessor</li> |
| </ul> |
| |
| <h2 id="test">Test</h2> |
| |
| <p>This is only required when running tests:</p> |
| |
| <ul> |
| <li>Test::Exception</li> |
| </ul> |
| |
| <h3 id="httpclient-transport">HttpClient Transport</h3> |
| |
| <p>These are only required if using Thrift::HttpClient:</p> |
| |
| <ul> |
| <li>HTTP::Request</li> |
| <li>IO::String</li> |
| <li>LWP::UserAgent</li> |
| </ul> |
| |
| <h3 id="ssltls">SSL/TLS</h3> |
| |
| <p>These are only required if using Thrift::SSLSocket or Thrift::SSLServerSocket:</p> |
| |
| <ul> |
| <li>IO::Socket::SSL</li> |
| </ul> |
| |
| <h1 id="breaking-changes">Breaking Changes</h1> |
| |
| <h2 id="section">0.10.0</h2> |
| |
| <p>The socket classes were refactored in 0.10.0 so that there is one package per |
| file. This means <code>use Socket;</code> no longer defines SSLSocket. You can use this |
| technique to make your application run against 0.10.0 as well as earlier versions:</p> |
| |
| <p><code>eval { require Thrift::SSLSocket; } or do { require Thrift::Socket; }</code></p> |
| |
| <h2 id="section-1">0.11.0</h2> |
| |
| <ul> |
| <li>Namespaces of packages that were not scoped within Thrift have been fixed. |
| ** TApplicationException is now Thrift::TApplicationException |
| ** TException is now Thrift::TException |
| ** TMessageType is now Thrift::TMessageType |
| ** TProtocolException is now Thrift::TProtocolException |
| ** TProtocolFactory is now Thrift::TProtocolFactory |
| ** TTransportException is now Thrift::TTransportException |
| ** TType is now Thrift::TType</li> |
| </ul> |
| |
| <p>If you need a single version of your code to work with both older and newer thrift |
| namespace changes, you can make the new, correct namespaces behave like the old ones |
| in your files with this technique to create an alias, which will allow you code to |
| run against either version of the perl runtime for thrift:</p> |
| |
| <p><code>BEGIN {*TType:: = *Thrift::TType::}</code></p> |
| |
| <ul> |
| <li>Packages found in Thrift.pm were moved into the Thrift/ directory in separate files: |
| ** Thrift::TApplicationException is now in Thrift/Exception.pm |
| ** Thrift::TException is now in Thrift/Exception.pm |
| ** Thrift::TMessageType is now in Thrift/MessageType.pm |
| ** Thrift::TType is now in Thrift/Type.pm</li> |
| </ul> |
| |
| <p>If you need to modify your code to work against both older or newer thrift versions, |
| you can deal with these changes in a backwards compatible way in your projects using eval:</p> |
| |
| <p><code>eval { require Thrift::Exception; require Thrift::MessageType; require Thrift::Type; } |
| or do { require Thrift; }</code></p> |
| |
| <h1 id="deprecations">Deprecations</h1> |
| |
| <h2 id="section-2">0.11.0</h2> |
| |
| <p>Thrift::HttpClient setRecvTimeout() and setSendTimeout() are deprecated. |
| Use setTimeout instead.</p> |
