Mychem 0.8.1: more than just a bug fix

Mychem 0.8.1 has been released on 2010-09-07.

This version fix an important bug. All functions using serialized obmol type were impacted. The problem has been resolved by using the solution published by the pgchem project.

Mychem is now fully usable with MySQL 5.0 and 5.1. It should also be working with MySQL 4.1, but it has not been tested.

The bug list is now empty. I'm waiting for new providers!

The version 2.2.0 of Chemical Structures is released!

The Chemical Structures Project
The Chemical Structures Project provides a set of molecular structures. Each structure is stored in a CML file, that contains the 3D coordinates and some properties of the chemical compound. The project provides also a HTML interface for accessing the data. Two types of archive are available to download:
- a source archive, that contains only CML files and tools for building the HTML files
- a binary archive, that contains the HTML files and the structure as CML and MOL files.

For a better overview, look at the online version!

The version 2.2.0 of Chemical Structure has been released on 2009-07-08. It is a stable upgrade and provides several enhancement. The main changes and fixes are:
  • Traditional Chinese translation added
  • New compound categories:
    • Natural products
    • Peptides
  • New structures added:
    • 4-Aminobutanoic acid
    • Tetrahydropyran
    • Pyrrol-2-one
    • 1,5-Dihydro-2H-pyrrol-2-one
    • Norepinephrine
    • Coelenterazine

Major fix in Mychem

A major bug has been fixed into Mychem. Fredrik Wallner has posted the main patch.
In some case, the return value of Mychem functions was blank and no error were raised.
Fredrik Wallner has founded that setting a character at the end of the string to '\0' fixes this issue.

The old code:
const char *inputMol = args->args[0];

The new code:
char *inputMol = (char *) malloc(sizeof(char)*(args->lengths[0]+1));
strncpy(inputMol, args->args[0], args->lengths[0]);
inputMol[args->lengths[0]] = 0;

This indicates that the character string given by MySQL as parameter does not contains the '\0' character at the end.

Many thanks to Fredrik Wallner !

The road is now open to go to the next release (0.6.0)
