the robot is my test environment

C is my favorite programming language :-)

>
>
> [2.4] Do you feel that libwww too big?

It's not only to big, it is too complicated. Especially the eventloop part
and the way the different modules work together.
You easily get lost and drowned in the streams.

>
>
> [x] Yes
> [ ] No
>
> [2.5] If so, which parts would you like to remove, or move to other
libraries

The eventloop, all protocols except ftp and http(s)

>
>
> [2.6] What are the things that you like the most of libwww

the callback functions philosophy

>
>
> [2.7] What are the things that you dislike the most of libwww

the eventloop, the lack of meaningfull comments, the usually complicated
call-stack with a lot of wrapper functions.
The permanent threat by deadlocks and blocking situations which are nearly
impossible to locate. (What can anyone do if the robot hangs after a ten
minutes run?)
Debugging an application using libwww is a horror.

>
>
> [2.8] What are the things that you would like to change in libwww

The handling of parallel events. (Threads)


>
>
> [2.9] What are the things you think that libwww are missing

a better support for ssl

>
>
> [2.10] Anything else you'd like to say

I would like to emphasize a recent comment:
libwww is not really a library, it is an application allowing to extend
parts of its functionality by callback functions

>
>
> ---------------------------------------------------------------------

something easy/easier to use and to understand.

I don't know.

not just libraries. (I doubt that libwww is a library - see 2.10) Some of
the functionality I have seen in perl (CPAN), apache http://www.apache.org  and
ht-dig: http://www.htdig.org/

  [x] Maybe (if we come to a more stable state)

a. I understand too little of the inner working of libwww.
b. I am not a native english speaker.

the only parts of libwww that are useful for me outside the context of
libwww are the string handling and parsing functions

java

I think it is a good idea to launch this survey.
Thank you.
