PHP Linux Windows ASP.NET Performance – Redux !

Posted: 13 Aug 2009 07:22 AM PDT

Last week I posted some comparative performance result that I got from comparing the relative performance of PHP on PHP 5.2 to PHP 5.3, PHP on Linux to PHP on Windows and PHP to ASP.NET. First, I want to thank the PHP community for their responses. With only a few exceptions the PHP community proved that they are not a bunch of teenage jealous (anymore :) ? ) but rather a group of professionals, confident in their work and ready to engage in respectful dialog. A couple of my friends in the PHP community (See: to Andi Gutmans & Brandon Savage ) took exception to the perf results – and for fair reason. In my tests I declined to install PHP op-code caching for my tests because its not installed on some of the hosts I use and is not built in...(read more)

Business Apps Example for Silverlight 3 RTM and .NET RIA Services July Update: Part 22: Separate Solution Files

Posted: 11 Aug 2009 08:47 PM PDT

Still updating my Mix 09 Silverlight 3 + RIA Services talk with more fun stuff. This time I take up a challenge from Mr. Wildermuth . Shawn recently raised a very interesting issue with RIA Services development. He works with a lot of large enterprises that need to have separate solution files for their client and server projects. Generally we recommend the RIA Services Class Library projects for this sort of thing. But there are some cases where even more flexibility is needed. To take up this challenge, I have factored my (now famous?) SuperEmployee's app into two solutions: one from client and one for server. You can see the full series here . The demo requires (all 100% free and always free): VS2008 SP1 Silverlight 3 RTM .NET RIA Services...(read more)

WCF REST Starter Kit Codeplex Preview 2

Posted: 13 Mar 2009 09:19 AM PDT

Preview 2 posted to CodePlex, adding new client capabilities that we think should really make client-side REST development easier. Chief among the new functionality included in Preview 2 is a new class that provides a staged pipeline model for requesting resources over the web. Using this new HTTP client class allows the developer to plug into the various stages of communication to handle custom authentication, caching, and fault handling outside of the client's application logic.

Tag Parsing C++

Posted: 12 Aug 2009 10:59 AM PDT

Hello, my name is Thierry Miceli and I am a developer on the Visual C++ Compiler Front End team. Although our team is mostly known for writing and maintaining the part of the C++ compiler that analyzes your source code and builds an internal representation from it, a great deal of our effort in the last few years has been directed into servicing the IDE and improving the intellisense experience (refreshers here, here, and here).

Today, I am going to write about a new parser that has been specifically created to provide a fast and scalable way to extract information from C++ source code. This parser is one of our new additions to Visual Studio 2010 and we call it the "tag parser".

The tag parser is used in Visual Studio 2010 to populate the SQL database that supersedes the NCB file. All of the browsing features of VC++ rely in some way on results provided by the tag parser. These include Class View, Call Hierarchy, Go To Definition/Declaration, Get All References, Quick Search, the Navigation Bar and VCCodeModel.

A Fuzzy Parser

It is a fuzzy parser, which means that instead of trying to strictly recognize and validate the full C++ syntax (we have an excellent compiler front-end to do that) it lazily matches an input stream of tokens with some patterns. This parser doesn't populate a symbol table during parsing, it has no notion of types apart from built-in ones, it doesn't build a full macro context and its unit of translation is a single file (i.e. it doesn't follow through #include directives). But nevertheless, the parser is able to deal with all of C++, C++/CLI and IDL.

High level of tolerance to incomplete code and errors.

The tag parser doesn't try to make sense of every symbol or identifier in the source code. It will be satisfied with being able to recognize the different parts of a declaration and their positions in the source file. If a name in the type specification of a declaration couldn't get resolved by our C++ compiler this would not prevent the tag parser from recognizing the declaration and it will show up in Class View as in the example below.

The tag parser is somewhat analogous to a human reader of the source code that would just be looking at one unique declaration without knowing much about the rest of the project. He may not know what most identifiers actually represent but he can tell with a high level of confidence what the declaration is and locate its subparts.

In addition to the tolerance to 'semantically' incorrect code which is a property of fuzzy parsers, the tag parser has heuristic based error recovery for the most common causes of erroneous code during editing. For example, it will try to detect incomplete declarations or unclosed body of functions definitions as shown in the snapshot below.

Dealing with preprocessor conditional directives.

The tag parser's main role is to extract information from the source code that is then consumed by the IDE browsing features. Because browsing features closely relate to the editing experience it is more useful that the tag parser generates a structured representation of the full source code as it appears in the editor rather than a representation of the code that would get compiled under a specific project configuration.

The tag parser deals with preprocessor conditional directives (#if, #ifdef, #ifndef, #else, #elif,
