• unistd.h is not part of Visual Studio
• add a check for that in zoo-kernel/service_internal.h, around line#80, such as:

    #if !defined(USE_RUBY) && !defined(WIN32)
    #include <unistd.h>
    #endif
  

Cordial greetings this league is to ask them about the zoo kernel configuration and Llosa other services required for an application where you can obtain terrain profiles similar to zoo-project done so far I am doing step by step tutorial offers zoo-project in its official website but cost me some difficulty to .. I hope you can help me with this and in advance thank you very much!

I know that the current release is a proof of concept, so this request is related to the next release, but attached to the current.

While working on GIS GRASS ZOO integration, i faced several issues and obstacles using the zoo-kernel.

• Parsing wrong commands from command line, or config files with incorrect content, as well as wrong python function bindings resulting in segfaults, which is a kind of frustrating finding errors while attaching new services.
• There are inconsistencies between the command line interface and the cgi interface for Python services (different number of function arguments -> map, input and output vs. input, output)
• Massive use of sprintf and strcmp instead of the more secure versions snprintf and strncmp
• No check of correct memory allocation
• Missing error messages in case something goes wrong with command line parsing, config file parsing and Python function bindings
• Mixing C and C++ code (malloc and new operator used in one file)
• The code need to be re-fractured to split huge functions into smaller parts to reduce redundancy and enhance the stability and maintainability
• Better indention for better readability and maintainability
• more issues will be added as new tickets

Hence i have modified several files in zoo-kernel because of security and stability reasons and added additionally debug output. The modification are made in the kernel and the python loader part.

• Most of the memory allocation is now checked and warnings are printed if memory allocation fails
• I have replaced sprintf with snprintf when possible
• I have replaced strcmp with strncmp when possible
• IMHO wrong memory allocation was fixed
• Indention style for zoo_loader.c changed for better readability (using indent on Linux)

I may have implemented new bugs while trying to reduce them. :/ So intensive testing is needed.

Patch is attached.
