Things to do in project cURL. Please tell us what you think, contribute and
|
|
send us patches that improve things! Also check the http://curl.haxx.se/dev
|
|
web section for various technical development notes.

LIBCURL
|
|
|
|
* Introduce an interface to libcurl that allows applications to easier get to
|
|
know what cookies that are received. Pushing interface that calls a
|
|
callback on each received cookie? Querying interface that asks about
|
|
existing cookies? We probably need both. Enable applications to modify
|
|
existing cookies as well.
|
|
|
|
* Make content encoding/decoding internally be made using a filter system.
|
|
|
|
* Introduce another callback interface for upload/download that makes one
|
|
less copy of data and thus a faster operation.
|
|
[http://curl.haxx.se/dev/no_copy_callbacks.txt]
|
|
|
|
* Add asynchronous name resolving (http://libdenise.sf.net/). This should be
|
|
made to work on most of the supported platforms, or otherwise it isn't
|
|
really interesting.
|
|
|
|
* Data sharing. Tell which easy handles within a multi handle that should
|
|
share cookies, connection cache, dns cache, ssl session cache. Full
|
|
suggestion found here: http://curl.haxx.se/dev/sharing.txt
|
|
|
|
* Mutexes. By adding mutex callback support, the 'data sharing' mentioned
|
|
above can be made between several easy handles running in different threads
|
|
too. The actual mutex implementations will be left for the application to
|
|
implement, libcurl will merely call 'getmutex' and 'leavemutex' callbacks.
|
|
Part of the sharing suggestion at: http://curl.haxx.se/dev/sharing.txt
|
|
|
|
* Set the SO_KEEPALIVE socket option to make libcurl notice and disconnect
|
|
very long time idle connections.
|
|
|
|
* Go through the code and verify that libcurl deals with big files >2GB and
|
|
>4GB all over. Bug reports (and source reviews) indicate that it doesn't
|
|
currently work properly.
|
|
|
|
* CURLOPT_MAXFILESIZE. Prevent downloads that are larger than the specified
|
|
size. CURLE_FILESIZE_EXCEEDED would then be returned. Gautam Mani
|
|
requested. That is, the download should not even begin but be aborted
|
|
immediately.
|
|
|
|
* Allow the http_proxy (and other) environment variables to contain user and
|
|
password as well in the style: http://proxyuser:proxypasswd@proxy:port
|
|
Berend Reitsma suggested.
|
|
|
|
LIBCURL - multi interface
|
|
|
|
* Make sure we don't ever loop because of non-blocking sockets return
|
|
EWOULDBLOCK or similar. This FTP command sending, the SSL connection etc.
|
|
|
|
* Make transfers treated more carefully. We need a way to tell libcurl we
|
|
have data to write, as the current system expects us to upload data each
|
|
time the socket is writable and there is no way to say that we want to
|
|
upload data soon just not right now, without that aborting the upload. The
|
|
opposite situation should be possible as well, that we tell libcurl we're
|
|
ready to accept read data. Today libcurl feeds the data as soon as it is
|
|
available for reading, no matter what.
|
|
|
|
DOCUMENTATION
|
|
|
|
* More and better
|
|
|
|
FTP
|
|
|
|
* Make CURLOPT_FTPPORT support an additional port number on the IP/if/name,
|
|
like "blabla:[port]" or possibly even "blabla:[portfirst]-[portsecond]".
|
|
|
|
* FTP ASCII upload does not follow RFC959 section 3.1.1.1: "The sender
|
|
converts the data from an internal character representation to the standard
|
|
8-bit NVT-ASCII representation (see the Telnet specification). The
|
|
receiver will convert the data from the standard form to his own internal
|
|
form."
|
|
|
|
* Since USERPWD always override the user and password specified in URLs, we
|
|
might need another way to specify user+password for anonymous ftp logins.
|
|
|
|
* An option to only download remote FTP files if they're newer than the local
|
|
one is a good idea, and it would fit right into the same syntax as the
|
|
already working http dito works (-z). It of course requires that 'MDTM'
|
|
works, and it isn't a standard FTP command.
|
|
|
|
* Add FTPS support with SSL for the data connection too. This should be made
|
|
according to the specs written in draft-murray-auth-ftp-ssl-08.txt,
|
|
"Securing FTP with TLS"
|
|
|
|
* --disable-epsv exists, but for active connections we have no --disable-eprt
|
|
(or even --disable-lprt).
|
|
|
|
HTTP
|
|
|
|
* If the "body" of the POST is < MSS it really aught to be sent along with
|
|
the headers. More generally, if the last chunk of the POST body is < MSS,
|
|
it should be sent with the previous chunk (which may be the POST headers).
|
|
So long as any one send is larger than MSS (or there is only one send when
|
|
< MSS :), the Nagle Algorithm will not be a problem on any stack where
|
|
Nagle is implemented correctly. (pointed out by Rick Jones)
|
|
|
|
* Authentication: NTLM. Support for that MS crap called NTLM
|
|
authentication. MS proxies and servers sometime require that. Since that
|
|
protocol is a proprietary one, it involves reverse engineering and network
|
|
sniffing. This should however be a library-based functionality. There are a
|
|
few different efforts "out there" to make open source HTTP clients support
|
|
this and it should be possible to take advantage of other people's hard
|
|
work. http://modntlm.sourceforge.net/ is one. There's a web page at
|
|
http://www.innovation.ch/java/ntlm.html that contains detailed reverse-
|
|
engineered info.
|
|
|
|
* RFC2617 compliance, "Digest Access Authentication" A valid test page seem
|
|
to exist at: http://hopf.math.nwu.edu/testpage/digest/ And some friendly
|
|
person's server source code is available at
|
|
http://hopf.math.nwu.edu/digestauth/index.html Then there's the Apache
|
|
mod_digest source code too of course. It seems as if Netscape doesn't
|
|
support this, and not many servers do. Although this is a lot better
|
|
authentication method than the more common "Basic". Basic sends the
|
|
password in cleartext over the network, this "Digest" method uses a
|
|
challange-response protocol which increases security quite a lot.
|
|
|
|
* Pipelining. Sending multiple requests before the previous one(s) are done.
|
|
This could possibly be implemented using the multi interface to queue
|
|
requests and the response data.
|
|
|
|
TELNET
|
|
|
|
* Make TELNET work on windows98!
|
|
|
|
* Reading input (to send to the remote server) on stdin is a crappy solution
|
|
for library purposes. We need to invent a good way for the application to
|
|
be able to provide the data to send.
|
|
|
|
* Move the telnet support's network select() loop go away and merge the code
|
|
into the main transfer loop. Until this is done, the multi interface won't
|
|
work for telnet.
|
|
|
|
SSL
|
|
|
|
* If you really want to improve the SSL situation, you should probably have a
|
|
look at SSL cafile loading as well - quick traces look to me like these are
|
|
done on every request as well, when they should only be necessary once per
|
|
ssl context (or once per handle). Even better would be to support the SSL
|
|
CAdir option - instead of loading all of the root CA certs for every
|
|
request, this option allows you to only read the CA chain that is actually
|
|
required (into the cache)...
|
|
|
|
* Add an interface to libcurl that enables "session IDs" to get
|
|
exported/imported. Cris Bailiff said: "OpenSSL has functions which can
|
|
serialise the current SSL state to a buffer of your choice, and
|
|
recover/reset the state from such a buffer at a later date - this is used
|
|
by mod_ssl for apache to implement and SSL session ID cache". This whole
|
|
idea might become moot if we enable the 'data sharing' as mentioned in the
|
|
LIBCURL label above.
|
|
|
|
* OpenSSL supports a callback for customised verification of the peer
|
|
certificate, but this doesn't seem to be exposed in the libcurl APIs. Could
|
|
it be? There's so much that could be done if it were! (brought by Chris
|
|
Clark)
|
|
|
|
* Make curl's SSL layer option capable of using other free SSL libraries.
|
|
Such as the Mozilla Security Services
|
|
(http://www.mozilla.org/projects/security/pki/nss/) and GNUTLS
|
|
(http://gnutls.hellug.gr/)
|
|
|
|
LDAP
|
|
|
|
* Look over the implementation. The looping will have to "go away" from the
|
|
lib/ldap.c source file and get moved to the main network code so that the
|
|
multi interface and friends will work for LDAP as well.
|
|
|
|
CLIENT
|
|
|
|
* Add an option that prevents cURL from overwiting existing local files. When
|
|
used, and there already is an existing file with the target file name
|
|
(either -O or -o), a number should be appended (and increased if already
|
|
existing). So that index.html becomes first index.html.1 and then
|
|
index.html.2 etc. Jeff Pohlmeyer suggested.
|
|
|
|
* "curl ftp://site.com/*.txt"
|
|
|
|
* Several URLs can be specified to get downloaded. We should be able to use
|
|
the same syntax to specify several files to get uploaded (using the same
|
|
persistant connection), using -T.
|
|
|
|
* When the multi interface has been implemented and proved to work, the
|
|
client could be told to use maximum N simultaneous transfers and then just
|
|
make sure that happens. It should of course not make more than one
|
|
connection to the same remote host.
|
|
|
|
* Extending the capabilities of the multipart formposting. How about leaving
|
|
the ';type=foo' syntax as it is and adding an extra tag (headers) which
|
|
works like this: curl -F "coolfiles=@fil1.txt;headers=@fil1.hdr" where
|
|
fil1.hdr contains extra headers like
|
|
|
|
Content-Type: text/plain; charset=KOI8-R"
|
|
Content-Transfer-Encoding: base64
|
|
X-User-Comment: Please don't use browser specific HTML code
|
|
|
|
which should overwrite the program reasonable defaults (plain/text,
|
|
8bit...) (Idea brough to us by kromJx)
|
|
|
|
TEST SUITE
|
|
|
|
* If perl wasn't found by the configure script, don't attempt to run the
|
|
tests but explain something nice why it doesn't.
|
|
|
|
* Extend the test suite to include more protocols. The telnet could just do
|
|
ftp or http operations (for which we have test servers).
|
|
|
|
* Make the test suite work on more platforms. OpenBSD and Mac OS. Remove
|
|
fork()s and it should become even more portable.
|
|
|
|
* Introduce a test suite that tests libcurl better and more explicitly.
|
|
|
|
NEXT MAJOR RELEASE
|
|
|
|
* curl_easy_cleanup() returns void, but curl_multi_cleanup() returns a
|
|
CURLMcode. These should be changed to be the same.
|
|
|
|
* curl_formparse() should be removed
