1.1 misho 1: How curl Became Like This
2: =========================
3:
4: Towards the end of 1996, Daniel Stenberg was spending time writing an IRC bot
5: for an Amiga related channel on EFnet. He then came up with the idea to make
6: currency-exchange calculations available to Internet Relay Chat (IRC)
7: users. All the necessary data were published on the Web; he just needed to
8: automate their retrieval.
9:
10: Daniel simply adopted an existing command-line open-source tool, httpget, that
11: Brazilian Rafael Sagula had written and recently released version 0.1 of. After
12: a few minor adjustments, it did just what he needed.
13:
14: 1997
15: ----
16:
17: HttpGet 1.0 was released on April 8th 1997 with brand new HTTP proxy support.
18:
19: We soon found and fixed support for getting currencies over GOPHER. Once FTP
20: download support was added, the name of the project was changed and urlget 2.0
21: was released in August 1997. The http-only days were already passed.
22:
23: 1998
24: ----
25:
26: The project slowly grew bigger. When upload capabilities were added and the
27: name once again was misleading, a second name change was made and on March 20,
28: 1998 curl 4 was released. (The version numbering from the previous names was
29: kept.)
30:
31: (Unrelated to this project a company called Curl Corporation registered a US
32: trademark on the name "CURL" on May 18 1998. That company had then already
33: registered the curl.com domain back in November of the previous year. All this
34: was revealed to us much later.)
35:
36: SSL support was added, powered by the SSLeay library.
37:
38: August: first announcement of curl on freshmeat.net.
39:
40: October: with the curl 4.9 release and the introduction of cookie support,
41: curl was no longer released under the GPL license. Now we're at 4000 lines of
42: code, we switched over to the MPL license to restrict the effects of
43: "copyleft".
44:
45: November: configure script and reported successful compiles on several
46: major operating systems. The never-quite-understood -F option was added and
47: curl could now simulate quite a lot of a browser. TELNET support was added.
48:
49: Curl 5 was released in December 1998 and introduced the first ever curl man
50: page. People started making Linux RPM packages out of it.
51:
52: 1999
53: ----
54:
55: January: DICT support added.
56:
57: OpenSSL took over and SSLeay was abandoned.
58:
59: May: first Debian package.
60:
61: August: LDAP:// and FILE:// support added. The curl web site gets 1300 visits
62: weekly. Moved site to curl.haxx.nu.
63:
64: September: Released curl 6.0. 15000 lines of code.
65:
66: December 28: added the project on Sourceforge and started using its services
67: for managing the project.
68:
69: 2000
70: ----
71:
72: Spring: major internal overhaul to provide a suitable library interface.
73: The first non-beta release was named 7.1 and arrived in August. This offered
74: the easy interface and turned out to be the beginning of actually getting
75: other software and programs to be based on and powered by libcurl. Almost
76: 20000 lines of code.
77:
78: June: the curl site moves to "curl.haxx.se"
79:
80: August, the curl web site gets 4000 visits weekly.
81:
82: The PHP guys adopted libcurl already the same month, when the first ever third
83: party libcurl binding showed up. CURL has been a supported module in PHP since
84: the release of PHP 4.0.2. This would soon get followers. More than 16
85: different bindings exist at the time of this writing.
86:
87: September: kerberos4 support was added.
88:
89: November: started the work on a test suite for curl. It was later re-written
90: from scratch again. The libcurl major SONAME number was set to 1.
91:
92: 2001
93: ----
94:
95: January: Daniel released curl 7.5.2 under a new license again: MIT (or
96: MPL). The MIT license is extremely liberal and can be combined with GPL
97: in other projects. This would finally put an end to the "complaints" from
98: people involved in GPLed projects that previously were prohibited from using
99: libcurl while it was released under MPL only. (Due to the fact that MPL is
100: deemed "GPL incompatible".)
101:
102: March 22: curl supports HTTP 1.1 starting with the release of 7.7. This
103: also introduced libcurl's ability to do persistent connections. 24000 lines of
104: code. The libcurl major SONAME number was bumped to 2 due to this overhaul.
105: The first experimental ftps:// support was added.
106:
107: August: curl is bundled in Mac OS X, 10.1. It was already becoming more and
108: more of a standard utility of Linux distributions and a regular in the BSD
109: ports collections. The curl web site gets 8000 visits weekly. Curl Corporation
110: contacted Daniel to discuss "the name issue". After Daniel's reply, they have
111: never since got back in touch again.
112:
113: September: libcurl 7.9 introduces cookie jar and curl_formadd(). During the
114: forthcoming 7.9.x releases, we introduced the multi interface slowly and
115: without many whistles.
116:
117: 2002
118: ----
119:
120: June: the curl web site gets 13000 visits weekly. curl and libcurl is
121: 35000 lines of code. Reported successful compiles on more than 40 combinations
122: of CPUs and operating systems.
123:
124: To estimate number of users of the curl tool or libcurl library is next to
125: impossible. Around 5000 downloaded packages each week from the main site gives
126: a hint, but the packages are mirrored extensively, bundled with numerous OS
127: distributions and otherwise retrieved as part of other software.
128:
129: September: with the release of curl 7.10 it is released under the MIT license
130: only.
131:
132: 2003
133: ----
134:
135: January: Started working on the distributed curl tests. The autobuilds.
136:
137: February: the curl site averages at 20000 visits weekly. At any given moment,
138: there's an average of 3 people browsing the curl.haxx.se site.
139:
140: Multiple new authentication schemes are supported: Digest (May), NTLM (June)
141: and Negotiate (June).
142:
143: November: curl 7.10.8 is released. 45000 lines of code. ~55000 unique visitors
144: to the curl.haxx.se site. Five official web mirrors.
145:
146: December: full-fledged SSL for FTP is supported.
