How curl Became Like This
|
|
=========================
|
|
|
|
Towards the end of 1996, Daniel Stenberg was spending time writing an IRC bot
|
|
for an Amiga related channel on EFnet. He then came up with the idea to make
|
|
currency-exchange calculations available to Internet Relay Chat (IRC)
|
|
users. All the necessary data were published on the Web; he just needed to
|
|
automate their retrieval.
|
|
|
|
1996
|
|
----
|
|
|
|
On November 11, 1996 the Brazilian developer Rafael Sagula wrote and released
|
|
HttpGet version 0.1.
|
|
|
|
Daniel extended this existing command-line open-source tool. After a few minor
|
|
adjustments, it did just what he needed. The first release with Daniel's
|
|
additions was 0.2, released on December 17, 1996. Daniel quickly became the
|
|
new maintainer of the project.
|
|
|
|
1997
|
|
----
|
|
|
|
HttpGet 0.3 was released in January 1997 and now it accepted HTTP URLs on the
|
|
command line.
|
|
|
|
HttpGet 1.0 was released on April 8th 1997 with brand new HTTP proxy support.
|
|
|
|
We soon found and fixed support for getting currencies over GOPHER. Once FTP
|
|
download support was added, the name of the project was changed and urlget 2.0
|
|
was released in August 1997. The http-only days were already passed.
|
|
|
|
Version 2.2 was released on August 14 1997 and introduced support to build for
|
|
and run on Windows and Solaris.
|
|
|
|
November 24 1997: Version 3.1 added FTP upload support.
|
|
|
|
Version 3.5 added support for HTTP POST.
|
|
|
|
1998
|
|
----
|
|
|
|
February 4: urlget 3.10
|
|
|
|
February 9: urlget 3.11
|
|
|
|
March 14: urlget 3.12 added proxy authentication.
|
|
|
|
The project slowly grew bigger. With upload capabilities, the name was once
|
|
again misleading and a second name change was made. On March 20, 1998 curl 4
|
|
was released. (The version numbering from the previous names was kept.)
|
|
|
|
(Unrelated to this project a company called Curl Corporation registered a US
|
|
trademark on the name "CURL" on May 18 1998. That company had then already
|
|
registered the curl.com domain back in November of the previous year. All this
|
|
was revealed to us much later.)
|
|
|
|
SSL support was added, powered by the SSLeay library.
|
|
|
|
August: first announcement of curl on freshmeat.net.
|
|
|
|
October: with the curl 4.9 release and the introduction of cookie support,
|
|
curl was no longer released under the GPL license. Now we are at 4000 lines of
|
|
code, we switched over to the MPL license to restrict the effects of
|
|
"copyleft".
|
|
|
|
November: configure script and reported successful compiles on several
|
|
major operating systems. The never-quite-understood -F option was added and
|
|
curl could now simulate quite a lot of a browser. TELNET support was added.
|
|
|
|
Curl 5 was released in December 1998 and introduced the first ever curl man
|
|
page. People started making Linux RPM packages out of it.
|
|
|
|
1999
|
|
----
|
|
|
|
January: DICT support added.
|
|
|
|
OpenSSL took over and SSLeay was abandoned.
|
|
|
|
May: first Debian package.
|
|
|
|
August: LDAP:// and FILE:// support added. The curl website gets 1300 visits
|
|
weekly. Moved site to curl.haxx.nu.
|
|
|
|
September: Released curl 6.0. 15000 lines of code.
|
|
|
|
December 28: added the project on Sourceforge and started using its services
|
|
for managing the project.
|
|
|
|
2000
|
|
----
|
|
|
|
Spring: major internal overhaul to provide a suitable library interface.
|
|
The first non-beta release was named 7.1 and arrived in August. This offered
|
|
the easy interface and turned out to be the beginning of actually getting
|
|
other software and programs to be based on and powered by libcurl. Almost
|
|
20000 lines of code.
|
|
|
|
June: the curl site moves to "curl.haxx.se"
|
|
|
|
August, the curl website gets 4000 visits weekly.
|
|
|
|
The PHP guys adopted libcurl already the same month, when the first ever third
|
|
party libcurl binding showed up. CURL has been a supported module in PHP since
|
|
the release of PHP 4.0.2. This would soon get followers. More than 16
|
|
different bindings exist at the time of this writing.
|
|
|
|
September: kerberos4 support was added.
|
|
|
|
November: started the work on a test suite for curl. It was later re-written
|
|
from scratch again. The libcurl major SONAME number was set to 1.
|
|
|
|
2001
|
|
----
|
|
|
|
January: Daniel released curl 7.5.2 under a new license again: MIT (or
|
|
MPL). The MIT license is extremely liberal and can be combined with GPL
|
|
in other projects. This would finally put an end to the "complaints" from
|
|
people involved in GPLed projects that previously were prohibited from using
|
|
libcurl while it was released under MPL only. (Due to the fact that MPL is
|
|
deemed "GPL incompatible".)
|
|
|
|
March 22: curl supports HTTP 1.1 starting with the release of 7.7. This
|
|
also introduced libcurl's ability to do persistent connections. 24000 lines of
|
|
code. The libcurl major SONAME number was bumped to 2 due to this overhaul.
|
|
The first experimental ftps:// support was added.
|
|
|
|
August: The curl website gets 8000 visits weekly. Curl Corporation contacted
|
|
Daniel to discuss "the name issue". After Daniel's reply, they have never
|
|
since got back in touch again.
|
|
|
|
September: libcurl 7.9 introduces cookie jar and curl_formadd(). During the
|
|
forthcoming 7.9.x releases, we introduced the multi interface slowly and
|
|
without many whistles.
|
|
|
|
September 25: curl (7.7.2) is bundled in Mac OS X (10.1) for the first time. It was
|
|
already becoming more and more of a standard utility of Linux distributions
|
|
and a regular in the BSD ports collections.
|
|
|
|
2002
|
|
----
|
|
|
|
June: the curl website gets 13000 visits weekly. curl and libcurl is
|
|
35000 lines of code. Reported successful compiles on more than 40 combinations
|
|
of CPUs and operating systems.
|
|
|
|
To estimate the number of users of the curl tool or libcurl library is next to
|
|
impossible. Around 5000 downloaded packages each week from the main site gives
|
|
a hint, but the packages are mirrored extensively, bundled with numerous OS
|
|
distributions and otherwise retrieved as part of other software.
|
|
|
|
October 1: with the release of curl 7.10 it is released under the MIT license
|
|
only.
|
|
|
|
Starting with 7.10, curl verifies SSL server certificates by default.
|
|
|
|
2003
|
|
----
|
|
|
|
January: Started working on the distributed curl tests. The autobuilds.
|
|
|
|
February: the curl site averages at 20000 visits weekly. At any given moment,
|
|
there's an average of 3 people browsing the website.
|
|
|
|
Multiple new authentication schemes are supported: Digest (May), NTLM (June)
|
|
and Negotiate (June).
|
|
|
|
November: curl 7.10.8 is released. 45000 lines of code. ~55000 unique visitors
|
|
to the website. Five official web mirrors.
|
|
|
|
December: full-fledged SSL for FTP is supported.
|
|
|
|
2004

|

|
|
|
|
January: curl 7.11.0 introduced large file support.
|
|
|
|
June: curl 7.12.0 introduced IDN support. 10 official web mirrors.

|
|
curl_formparse() function
