At the time + of writing (January 2013), there are about 83,000 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. + +1.2 Where to report + + If you can't fix a bug yourself and submit a fix for it, try to report an as + detailed report as possible to a curl mailing list to allow one of us to + have a go at a solution. You can optionally also post your bug/problem at + curl's bug tracking system over at + + https://sourceforge.net/p/curl/bugs/ + + Please read the rest of this document below first before doing that! Also, + you need to login to your sourceforge account before being able to submit a + bug report (necessary evil done to avoid spam). + + If you feel you need to ask around first, find a suitable mailing list and + post there. The lists are available on http://curl.haxx.se/mail/ + +1.3 What to report + + When reporting a bug, you should include all 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 tell us: + + - your operating system's name and version number + + - what version of curl you're using (curl -V is fine) + + - versions of the used libraries that libcurl is built to use + + - what URL you were working with (if possible), at least which protocol + + and anything and everything else you think matters. Tell us what you + expected to happen, tell use what did happen, tell us how you could make it + work another way. Dig around, try out, test. Then include all the tiny bits + and pieces in your report. You will benefit from this yourself, as it will + enable us to help you quicker and more accurately. + + Since curl deals with networks, it often helps us if you include a protocol + debug dump with your bug report. The output you get by using the -v or + --trace options. + + 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. Instead we ask you to get a stack + trace and send that (much smaller) output to us instead! + + The address and how to subscribe to the mailing lists are detailed in the + MANUAL file. + +1.4 libcurl problems + + First, post all libcurl problems on the curl-library mailing list. + + When you've written your own application with libcurl to perform transfers, + it is even more important to be specific and detailed when reporting bugs. + + Tell us the libcurl version and your operating system. Tell us the name and + version of all relevant sub-components like for example the SSL library + you're using and what name resolving your libcurl uses. If you use SFTP or + SCP, the libssh2 version is relevant etc. + + Showing us a real source code example repeating your problem is the best way + to get our attention and it will greatly increase our chances to understand + your problem and to work on a fix (if we agree it truly is a problem). + + Lots of problems that appear to be libcurl problems are actually just abuses + of the libcurl API or other malfunctions in your applications. It is advised + that you run your problematic program using a memory debug tool like + valgrind or similar before you post memory-related or "crashing" problems to + us. + +1.5 Who will fix the problems + + If the problems or bugs you describe are considered to be bugs, we want to + have the problems fixed. + + There are no developers in the curl project that are paid to work on bugs. + All developers that take on reported bugs do this on a voluntary basis. We + do it out of an ambition to keep curl and libcurl excellent products and out + of pride. + + But please do not assume that you can just lump over something to us and it + will then magically be fixed after some given time. Most often we need + feedback and help to understand what you've experienced and how to repeat a + problem. Then we may only be able to assist YOU to debug the problem and to + track down the proper fix. + + We get reports from many people every month and each report can take a + considerable amount of time to really go to the bottom with. + +1.6 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 cores. + + 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. + +1.7 Bugs in libcurl bindings + + There will of course pop up bugs in libcurl bindings. You should then + primarily approach the team that works on that particular binding and see + what you can do to help them fix the problem. + + If you suspect that the problem exists in the underlying libcurl, then + please convert your program over to plain C and follow the steps outlined + above. |
