-  Date: February 11, 2007
-  Author: Daniel Stenberg <daniel@haxx.se>
-  URL: http://curl.haxx.se/legal/distro-dilemma.html
-
-Condition
-
- This document is written to describe the situation as it is right now.
- libcurl 7.16.1 is currently the latest version available. Things may of
- course change in the future.
-
- This document reflects my view and understanding of these things. Please tell
- me where and how you think I'm wrong, and I'll try to correct my mistakes.
-
-Background
-
- The Free Software Foundation has deemed the Original BSD license[1] to be
- "incompatible"[2] with GPL[3]. I'd rather say it is the other way around, but
- the point is the same: if you distribute a binary version of a GPL program,
- it MUST NOT be linked with any Original BSD-licensed parts or libraries.
- Doing so will violate the GPL license. For a long time, very many GPL
- licensed programs have avoided this license mess by adding an exception[8] to
- their license. And many others have just closed their eyes for this problem.
-
- libcurl is MIT-style[4] licensed - how on earth did this dilemma fall onto
- our plates?
-
- libcurl is only a little library. libcurl can be built to use OpenSSL for its
- SSL/TLS capabilities. OpenSSL is basically Original BSD licensed[5].
-
- If libcurl built to use OpenSSL is used by a GPL-licensed application and you
- decide to distribute a binary version of it (Linux distros - for example -
- tend to), you have a clash. GPL vs Original BSD.
-
- This dilemma is not libcurl-specific nor is it specific to any particular
- Linux distro. (This article mentions and refers to Debian several times, but
- only because Debian seems to be the only Linux distro to have faced this
- issue yet since no other distro is shipping libcurl built with two SSL
- libraries.)
-
-Part of the Operating System
-
- This would not be a problem if the used lib would be considered part of the
- underlying operating system, as then the GPL license has an exception
- clause[6] that allows applications to use such libs without having to be
- allowed to distribute it or its sources. Possibly some distros will claim
- that OpenSSL is part of their operating system.
-
- Debian does however not take this stance and has officially(?) claimed that
- OpenSSL is not a required part of the Debian operating system
-
- Some people claim that this paragraph cannot be exploited this way by a Linux
- distro, but I am not a lawyer and that is a discussion left outside of this
- document.
-
-GnuTLS
-
- Since May 2005 libcurl can get built to use GnuTLS instead of OpenSSL. GnuTLS
- is an LGPL[7] licensed library that offers a matching set of features as
- OpenSSL does. Now, you can build and distribute an TLS/SSL capable libcurl
- without including any Original BSD licensed code.
-
- I believe Debian is the first (only?) distro that provides libcurl/GnuTLS
- packages.
-
-yassl
-
- libcurl can get also get built to use yassl for the TLS/SSL layer. yassl is a
- GPL[3] licensed library.
-
-
-GnuTLS vs OpenSSL vs yassl
-
- While these three libraries offer similar features, they are not equal.
- libcurl does not (yet) offer a standardized stable ABI if you decide to
- switch from using libcurl-openssl to libcurl-gnutls or vice-versa. The GnuTLS
- and yassl support is very recent in libcurl and it has not been tested nor
- used very extensively, while the OpenSSL equivalent code has been used and
- thus matured since 1999.
-
- GnuTLS
-   - LGPL licensed
-   - supports SRP
-   - lacks SSLv2 support
-   - lacks MD2 support (used by at least some CA certs)
-   - lacks the crypto functions libcurl uses for NTLM
-
- OpenSSL
-   - Original BSD licensed
-   - lacks SRP
-   - supports SSLv2
-   - older and more widely used
-   - provides crypto functions libcurl uses for NTLM
-   - libcurl can do non-blocking connects with it in 7.15.4 and later
-
- yassl
-   - GPL licensed
-   - much untested and unproven in the real work by (lib)curl users so we don't
-     know a lot about restrictions or benefits from using this
-
-The Better License, Original BSD, GPL or LGPL?
-
- It isn't obvious or without debate to any objective interested party that
- either of these licenses are the "better" or even the "preferred" one in a
- generic situation.
-
- Instead, I think we should accept the fact that the SSL/TLS libraries and
- their different licenses will fit different applications and their authors
- differently depending on the applications' licenses and their general usage
- pattern (considering how GPL and LGPL libraries for example can be burdensome
- for embedded systems usage).
-
- In Debian land, there seems to be a common opinion that LGPL is "maximally
- compatible" with apps while Original BSD is not. Like this:
-
-        https://lists.debian.org/debian-devel/2005/09/msg01417.html
-
-More SSL Libraries
-
- In libcurl, there's no stopping us here. There are more Open Source/Free
- SSL/TLS libraries out there and we would very much like to support them as
- well, to offer application authors an even wider scope of choice.
-
-Application Angle of this Problem
-
- libcurl is built to use one SSL/TLS library. It uses a single fixed name (by
- default) on the built/created lib file, and applications are built/linked to
- use that single lib. Replacing one libcurl instance with another one that
- uses the other SSL/TLS library might break one or more applications (due to
- ABI differences and/or different feature set). You want your application to
- use the libcurl it was built for.
-
-Project cURL Angle of this Problem
-
- We distribute libcurl and everyone may build libcurl with either library at
- their choice. This problem is not directly a problem of ours. It merely
- affects users - GPL application authors only - of our lib as it comes
- included and delivered on some distros.
-
- libcurl has different ABI when built with different SSL/TLS libraries due to
- these reasons:
-
- 1. No one has worked on fixing this. The mutex/lock callbacks should be set
-    with a generic libcurl function that should use the proper underlying
-    functions.
-

- 3. There might be some other subtle differences just because nobody has yet

-
-Distro Angle of this Problem
-
- To my knowledge there is only one distro that ships libcurl built with either
- OpenSSL or GnuTLS.
-
- Debian Linux is now (since mid September 2005) providing two different
- libcurl packages, one for libcurl built with OpenSSL and one built with
- GnuTLS. They use different .so names and can this both be installed in a
- single system simultaneously. This has been said to be a transitional system
- not desired to keep in the long run.

 URL(s) in a config file.
 
+If the given URL is missing a scheme name (such as "http://" or "ftp://" etc)
+then curl will make a guess based on the host. If the outermost sub-domain name
+matches DICT, FTP, IMAP, LDAP, POP3 or SMTP then that protocol will be used,
+otherwise HTTP will be used. Since 7.45.0 guessing can be disabled by setting a
+default protocol, see \fI--proto-default\fP for details.

 This option may be used any number of times. To control where this URL is
 written, use the \fI-o, --output\fP or the \fI-O, --remote-name\fP options.

+Pass the address of a 'struct curl_slist *' to receive a linked-list of

+Pass a pointer to a 'struct curl_tlssessioninfo *'.  The pointer will be
+initialized to refer to a 'struct curl_tlssessioninfo *' that will contain an
+enum indicating the SSL library used for the handshake and the respective
+internal TLS session structure of this underlying SSL library.

+CURLSSLBACKEND_GSKIT, CURLSSLBACKEND_POLARSSL, CURLSSLBACKEND_CYASSL,
+CURLSSLBACKEND_SCHANNEL, CURLSSLBACKEND_DARWINSSL or
+CURLSSLBACKEND_AXTLS. (Note that the OpenSSL forks are all reported as just
+OpenSSL here.)
+
+The \fIinternals\fP struct member will point to a TLS library specific pointer
+with the following underlying types:

+.SH DESCRIPTION
+This option tells libcurl to use \fIprotocol\fP if the URL is missing a scheme

+
+Use one of these protocol (scheme) names:
+
+dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3,
+pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp
+
+An unknown or unsupported protocol causes error
+\fICURLE_UNSUPPORTED_PROTOCOL\fP when libcurl parses a schemeless URL. Parsing
+happens when \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP is
+called. The protocols supported by libcurl will vary depending on how it was
+built. Use \fIcurl_version_info(3)\fP if you need a list of protocol names
+supported by the build of libcurl that you are using.
+
+This option does not change the default proxy protocol (http).
+
+Without this option libcurl would make a guess based on the host, see
+\fICURLOPT_URL(3)\fP for details.
