Cgipp v0.3 <-> Cgipp v0.2

The whole library has been simplified and reduced in size and complexity, and I have stopped using a cgiMain() function, which was heavily criticised by Arne Sletteng. I have removed some of the classes, changed names on others and put some functions inside classes where they made more sense. The changes can easily be summarized as:

  • CgiData is now named Cgipp, and is the main class of the system. The old cgiMain() function is also included in the constructor of Cgipp and an example start of a program can be: 
    main() {
  int found=0;
  Cgipp *cgi = new Cgipp();
  htmlTool doc(cout);
  doc.printHeader();
  char *name = cgi->getvar("name", 80, found);
  if (name) doc << "Name is " << name << br;

  delete cgi;
  return 0;
};
  • another change you may have noted in the above example is that the fetchString method now is named getvar which is both simpler to understand and shorter to write. Check the documentation for the names of the new methods.
  • The Toolbox-class was dependent on the CGI-library to work, but this dependency has been removed and the Toolbox-class can be used anywhere. Some methods have been removed to accomplish this. The toolbox class is also not part of the standard make, and to include it in the library you must edit the makefiles/fix the IDE-file.
  • The CgiEnv class has been simplified and many methods have been removed, if you need any of the old, see how I have made the methods and edit the source code (very easy). I did this to reduce the code-size.
  • The htmlTool class has lost some of it's useless methods which nobody used anyway.
  • You can now use the main() function to do what you want it to and not be forced to use a cgiMain() application.
    Cgicc <-> Cgipp v0.2

    Cgipp has changed quite a lot from Cgicc, but I have tried to maintain much of the old structure, to make the conversion from Cgicc to Cgipp as easy and trivial as possible. The most notable changes is:

  • CgiForm and CgiPackage has been combined into one class: CgiData, this solves many of the problems there was with this unnecessary separation.
  • Many bugs have been removed. I do not maintain a list, so I recommend that you compare the source code. Most (if not all) memory leaks have been removed.
  • Code size has in some cases been halved, but does the same job and more.
  • Needless logging has been removed or commented out.
  • Using a ostrstream for output was not too portable as I have had severe problems with this on IRIX where crashes occured seemingly random. This has been changed to ostream which means that people who prefer using a strstream may use it as any ostream. I also had a problem on many platforms if the programs crashed I got NO output at all where I do get output using e.g. cout/stdout.
  • Reduced the number of arguments to cgiMain() to two, from four. [Only Cgipp v0.2+]
  • htmlTool [Was: HTMLDocument] has become a subclass of ostream which makes it much easier to use and much more adaptable. It does accept all that the old HTMLDocument did, but has grown in possibilities (code size is half though). The file now also fits better into Dos' 8.3 filenames.
  • [Outdated :Removed much of the unecessary cleaning when bailing out. A speedy cgi-program should not use years to clean up something the OS (at least on unix) will do.] Much safer ways to clean up memory before leaving, and a better bound-checker has been included for better portabilitiy to PCs when run in DEBUG mode.
  • Easier installing on systems. Uses configure on unix-systems and includes IDE-file for various installs on PC.
  • Exceptionhandling and exceptionthrowing removed due to numerous internal compiler errors on different platforms. The programs I develop on my linux should work on solaris and the ones I develop on Solaris should be usable on IRIX too w/o internal compiler errors. The day we get good c++ compilers on unix I'll include exception handling. [Note: the DOS-version may get exception-handling soon quite simply because it works on Borland's compiler]
  • Added Toolbox class for the things I far too often use in all my programs..
  • Updated the whole library to compile and be used flawlessly on pcs, sun4, irix, osf, solaris, etc.. This takes time and effort and thorough testing which has been done now. [More testing on v0.2 should be done. Runs flawlessly on linux and DOS at least]
  • The CgiEnv class now has support for more types of environment variables than it had, including cookies.
  • Cgicc's promise of never returning variables as NULL was not kept, but is almost kept except for the PostData variable.
  • Most (if not all) freebie methods have been put in the classes where they belong. (Usually in a protected mode)
