These are problems known to exist at the time of this release. Feel free to join in and help us correct one or more of these! Also be sure to check the changelog of the current development status, as one or more of these problems may have been fixed since this was written! 20. valgrind errors occur too often when 'make test' is used. It is because too many third-party libs and tools have problems. When curl is built without --disable-shared, the testing is done with a front-end script which makes the valgrind testing include (ba)sh as well and that often causes valgrind errors. Either we improve the valgrind error scanner a lot to better identify (lib)curl errors only, or we disable valgrind checking by default. 19. FTP 3rd party transfers with the multi interface doesn't work. Test: define CURL_MULTIEASY, rebuild curl, run test case 230 - 232. 18. test case 57 has </test> that should be </client> but when corrected, the test case fails! 16. FTP URLs passed to curl may contain NUL (0x00) in the RFC 1738 <user>, <password>, and <fpath> components, encoded as "%00". The problem is that curl_unescape does not detect this, but instead returns a shortened C string. From a strict FTP protocol standpoint, NUL is a valid character within RFC 959 <string>, so the way to handle this correctly in curl would be to use a data structure other than a plain C string, one that can handle embedded NUL characters. From a practical standpoint, most FTP servers would not meaningfully support NUL characters within RFC 959 <string>, anyway (e.g., UNIX pathnames may not contain NUL). 15. Test case 241 fails on all systems that support IPv6 but that don't have the host name 'ip6-localhost' in /etc/hosts (or similar) since the test case uses that host name to test the IPv6 name to address resolver. 14. Test case 165 might fail on system which has libidn present, but with an old iconv version (2.1.3 is a known bad version), since it doesn't recognize the charset when named ISO8859-1. Changing the name to ISO-8859-1 makes the test pass, but instead makes it fail on Solaris hosts that use its native iconv. 13. curl version 7.12.2 fails on AIX if compiled with --enable-ares. The workaround is to combine --enable-ares with --disable-shared 12. When connecting to a SOCKS proxy, the (connect) timeout is not properly acknowledged after the actual TCP connect (during the SOCKS "negotiate" phase). Pointed out by Lucas. Fix: need to select() and timeout properly. 11. Using configure --disable-[protocol] may cause 'make test' to fail for tests using the disabled protocol(s). 10. To get HTTP Negotiate authentication to work fine, you need to provide a (fake) user name (this concerns both curl and the lib) because the code wrongly only considers authentication if there's a user name provided. Bug report #1004841. How? http://curl.haxx.se/mail/lib-2004-08/0182.html 9. --limit-rate using -d or -F does not work. This is because the limit logic is provided by the curl app in its read/write callbacks, and when doing -d/-F the callbacks aren't used! Bug report #921395. 8. Doing resumed upload over HTTP does not work with '-C -', because curl doesn't do a HEAD first to get the initial size. This needs to be done manually for HTTP PUT resume to work, and then '-C [index]'. 7. CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD have no way of providing user names that contain a colon. This can't be fixed easily in a backwards compatible way without adding new options (and then, they should most probably allow setting user name and password separately). 6. libcurl ignores empty path parts in FTP URLs, whereas RFC1738 states that such parts should be sent to the server as 'CWD ' (without an argument). The only exception to this rule, is that we knowingly break this if the empty part is first in the path, as then we use the double slashes to indicate that the user wants to reach the root dir (this exception SHALL remain even when this bug is fixed). 5. libcurl doesn't treat the content-length of compressed data properly, as it seems HTTP servers send the *uncompressed* length in that header and libcurl thinks of it as the *compressed* length. Some explanations are here: http://curl.haxx.se/mail/lib-2003-06/0146.html 4. IPv6 support on AIX 4.3.3 doesn't work due to a missing sockaddr_storage struct. It has been reported to work on AIX 5.1 though. 3. GOPHER transfers seem broken 2. If a HTTP server responds to a HEAD request and includes a body (thus violating the RFC2616), curl won't wait to read the response but just stop reading and return back. If a second request (let's assume a GET) is then immediately made to the same server again, the connection will be re-used fine of course, and the second request will be sent off but when the response is to get read, the previous response-body is what curl will read and havoc is what happens. More details on this is found in this libcurl mailing list thread: http://curl.haxx.se/mail/lib-2002-08/0000.html 1. LDAP support requires that not only the OpenLDAP shared libraries be present at run time, but the development libraries (liblber.so and libldap.so) as well (not applicable to Windows).
