BUGS
Curl and libcurl have grown substantially since the beginning. At the time
of writing (mid March 2001), there are 23000 lines of source code, and by
the time you read this it has probably grown even more.
Of course there are lots of bugs left. And lots of misfeatures.
To help us make curl the stable and solid product we want it to be, we need
bug reports and bug fixes. If you can't fix a bug yourself and submit a fix
for it, try to report an as detailed report as possible to the curl mailing
list to allow one of us to have a go at a solution. You should also post
your bug/problem at curl's bug tracking system over at
http://sourceforge.net/bugs/?group_id=976
When reporting a bug, you should include information that will help us
understand what's wrong, what you expected to happen and how to repeat the
bad behavior. You therefore need to supply your operating system's name and
version number (uname -a under a unix is fine), what version of curl you're
using (curl -V is fine), what URL you were working with and anything else
you think matters.
Since curl deals with networks, it often helps us a lot if you include a
protocol debug dump with your bug report. The output you get by using the -v
flag. Usually, you also get more info by using -i so that is likely to be
useful when reporting bugs as well.
If curl crashed, causing a core dump (in unix), there is hardly any use to
send that huge file to anyone of us. Unless we have an exact same system
setup as you, we can't do much with it. What we instead ask of you is to get
a stack trace and send that (much smaller) output to us instead!
The address and how to subscribe to the mailing list is detailed in the
MANUAL file.
HOW TO GET A STACK TRACE
First, you must make sure that you compile all sources with -g and that you
don't 'strip' the final executable. Try to avoid optimizing the code as
well, remove -O, -O2 etc from the compiler options.
Run the program until it dumps core.
Run your debugger on the core file, like '<debugger> curl core'. <debugger>
should be replaced with the name of your debugger, in most cases that will
be 'gdb', but 'dbx' and others also occur.
When the debugger has finished loading the core file and presents you a
prompt, enter 'where' (without the quotes) and press return.
The list that is presented is the stack trace. If everything worked, it is
supposed to contain the chain of functions that were called when curl
crashed. Include the stack trace with your detailed bug report. It'll help a
lot.
