                                   Changelog
 
+Daniel (16 March 2006)
+- Tor Arntsen provided a RPM spec file for AIX Toolbox, that now is included
+  in the release archive.
 
+Daniel (14 March 2006)
+- David McCreedy fixed:
+
+  a bad SSL error message when OpenSSL certificates are verified fine.
+
+  a missing return code assignment in the FTP code
+
+Daniel (7 March 2006)
+- Markus Koetter filed debian bug report #355715 which identified a problem
+  with the multi interface and multi-part formposts. The fix from February
+  22nd could make the Curl_done() function get called twice on the same
+  connection and it was not designed for that and thus tried to call free() on
+  an already freed memory area!
+
+- Peter Heuchert made sure the CURLFTPSSL_CONTROL setting for CURLOPT_FTP_SSL
+  is used properly.
+
+Daniel (6 March 2006)
+- Lots of users on Windows have reported getting the "SSL: couldn't set
+  callback" error message so I've now made the setting of that callback not be
+  as critical as before. The function is only used for additional loggging/
+  trace anyway so a failure just means slightly less data. It should still be
+  able to proceed and connect fine to the server.
+
+Daniel (4 March 2006)
+- Thomas Klausner provided a patch written by Todd Vierling in bug report
+  #1442471 that fixes a build problem on Interix.
+
+Daniel (2 March 2006)
+- FTP upload without a file name part in the URL now causes
+  curl_easy_perform() to return CURLE_URL_MALFORMAT. Previously it allowed the
+  upload but named the file "(nil)" (without the quotes). Test case 524
+  verifies.
+
+- Added a check for getprotobyname in configure so that it'll be used, thanks
+  to Gisle Vanem's change the other day.
+
+Daniel (28 February 2006)
+- Dan Fandrich prevented curl from getting stuck in an endless loop in case we
+  are out of file handles very early in curl's code where it makes sure that
+  0, 1 and 2 aren't gonna be used by the lib for transfers.
+
+Daniel (27 February 2006)
+- Marty Kuhrt pointed out that there were two VMS-specific files missing in
+  the release archive.
+
+Version 7.15.2 (27 February 2006)
+
+Daniel (22 February 2006)
+- Lots of work and analysis by "xbx___" in bug #1431750
+  (http://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
+  different but related bugs:
+
+  1) Removing an easy handle from a multi handle before the transfer is done
+     could leave a connection in the connection cache for that handle that is
+     in a state that isn't suitable for re-use. A subsequent re-use could then
+     read from a NULL pointer and segfault.
+
+  2) When an easy handle was removed from the multi handle, there could be an
+     outstanding c-ares DNS name resolve request. When the response arrived,
+     it caused havoc since the connection struct it "belonged" to could've
+     been freed already.
+
+  Now Curl_done() is called when an easy handle is removed from a multi handle
+  pre-maturely (that is, before the transfer was complteted). Curl_done() also
+  makes sure to cancel all (if any) outstanding c-ares requests.
+
+Daniel (21 February 2006)
+- Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
+  type to the already provided type CURLPROXY_SOCKS4.
+
+  I added a --socks4 option that works like the current --socks5 option but
+  instead use the socks4 protocol.
+
+Daniel (20 February 2006)
+- Shmulik Regev fixed an issue with multi-pass authentication and compressed
+  content when libcurl didn't honor the internal ignorebody flag.
+
+Daniel (18 February 2006)
+- Ulf H<>rnhammar fixed a format string (printf style) problem in the Negotiate
+  code. It should however not be the cause of any troubles. He also fixed a
+  few similar problems in the HTTP test server code.
+
+Daniel (17 February 2006)
+- Shmulik Regev provided a fix for the DNS cache when using short life times,
+  as previously it could be holding on to old cached entries longer than
+  requested.
+
+Daniel (11 February 2006)
+- Karl Moerder added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options
+  that an app can use to let libcurl only connect to a remote host and then
+  extract the socket from libcurl. libcurl will then not attempt to do any
+  transfer at all after the connect is done.
+
+- Kent Boortz improved the configure check for GnuTLS to properly set LIBS
+  instead of LDFLAGS.
+
+Daniel (8 February 2006)
+- Philippe Vaucher provided a brilliant piece of test code that show a problem
+  with re-used FTP connections. If the second request on the same connection
+  was set not to fetch a "body", libcurl could get confused and consider it an
+  attempt to use a dead connection and would go acting mighty strange.
+
+Daniel (2 February 2006)
+- Make --limit-rate [num] mean bytes. It used to be that but it broke in my
+  change done in November 2005.
+
+Daniel (30 January 2006)
+- Added CURLOPT_LOCALPORT and CURLOPT_LOCALPORTRANGE to libcurl. Set with the
+  curl tool with --local-port. Plain and simply set the range of ports to bind
+  the local end of connections to. Implemented on to popular demand.
+
+- Based on an error report by Philippe Vaucher, we no longer count a retried
+  connection setup as a follow-redirect. It turns out 1) this fails when a FTP
+  connection is re-setup and 2) it does make the max-redirs counter behave
+  wrong.
+
+Daniel (24 January 2006)
+- Michal Marek provided a patch for FTP that makes libcurl continue to try
+  PASV even after EPSV returned a positive response code, if libcurl failed to
+  connect to the port number the EPSV response said. Obviously some people are
+  going through protocol-sensitive firewalls (or similar) that don't
+  understand EPSV and then they don't allow the second connection unless PASV
+  was used. This also called for a minor fix of test case 238.
+
+Daniel (20 January 2006)
+- Duane Cathey was one of our friends who reported that curl -P [IP]
+  (CURLOPT_FTPPORT) didn't work for ipv6-enabed curls if the IP wasn't a
+  "native" IP while it works fine for ipv6-disabled builds!
+
+  In the process of fixing this, I removed the support for LPRT since I can't
+  think of many reasons to keep doing it and asking on the mailing list didn't
+  reveal anyone else that could either. The code that sends EPRT and PORT is
+  now also a lot simpler than before (IMHO).
+
+Daniel (19 January 2006)
+- Jon Turner pointed out that doing -P [hostname] (CURLOPT_FTPPORT) with curl
+  (built ipv4-only) didn't work.
+
+Daniel (18 January 2006)
+- As reported in bug #1408742 (http://curl.haxx.se/bug/view.cgi?id=1408742),
+  the configure script complained about a missing "missing" script if you ran
+  configure within a path whose name included one or more spaces. This is due
+  to a flaw in automake (1.9.6 and earlier). I've now worked around it by
+  including an "overloaded" version of the AM_MISSING_HAS_RUN script that'll
+  be used instead of the one automake ships with. This kludge needs to be
+  removed once we get an automake version with this problem corrected.
+  Possibly we'll then need to convert this into a kludge depending on what
+  automake version that is used and that is gonna be painful and I don't even
+  want to think about that now...!
+
+Daniel (17 January 2006)
+- David Shaw: Here is the latest libcurl.m4 autoconf tests. It is updated with
+  the latest features and protocols that libcurl supports and has a minor fix
+  to better deal with the obscure case where someone has more than one libcurl
+  installed at the same time.
+
+Daniel (16 January 2006)
+- David Shaw finally removed all traces of Gopher and we are now officially
+  not supporting it. It hasn't been functioning for years anyway, so this is
+  just finally stating what already was true. And a cleanup at the same time.
+
+- Bryan Henderson turned the 'initialized' variable for curl_global_init()
+  into a counter, and thus you can now do multiple curl_global_init() and you
+  are then supposed to do the same amount of calls to curl_global_cleanup().
+  Bryan has also updated the docs accordingly.
+
+Daniel (13 January 2006)
+- Andrew Benham fixed a race condition in the test suite that could cause the
+  test script to kill all processes in the current process group!
+
+Daniel (12 January 2006)
+- Michael Jahn:
+
+  Fixed FTP_SKIP_PASV_IP and FTP_USE_EPSV to "do right" when used on FTP thru
+  HTTP proxy.
+
+  Fixed PROXYTUNNEL to work fine when you do ftp through a proxy.  It would
+  previously overwrite internal memory and cause unpredicted behaviour!
+
+Daniel (11 January 2006)
+- I decided to document the "secret option" here now, as I've received *NO*
+  feedback at all on my mailing list requests from November 2005:
+
+  I'm looking for feedback and comments. I added some experimental code the
+  other day, that allows a libcurl user to select what method libcurl should
+  use to reach a file on a FTP(S) server.
+
+  This functionality is available in CVS code and in recent daily snapshots.
+
+  Let me explain...
+
+  The current name for the option is CURLOPT_FTP_FILEMETHOD (--ftp-method for
+  the command line tool) and you set it to a long (there are currenly no
+  defines for the argument values, just plain numericals). You can set three
+  different "methods" that do this:
+
+  1 multicwd - like today, curl will do a single CWD operation for each path
+           part in the given URL. For deep hierarchies this means very many
+           commands. This is how RFC1738 says it should be done. This is the
+           default.
+
+  2 nocwd - no CWD at all is done, curl will do SIZE, RETR, STOR etc and give
+           a full path to the server.
+
+  3 singlecwd - make one CWD with the full target directory and then operate
+            on the file "normally".
+
+  (With the command line tool you do --ftp-method [METHOD], where [METHOD] is
+  one of "multicwd", "nocwd" or "singlecwd".)
+
+  What feedback I'm interested in:
+
+  1 - Do they work at all? Do you find servers where one of these don't work?
+
+  2 - What would proper names for the option and its arguments be, if we
+      consider this feature good enough to get included and documented in
+      upcoming releases?
+
+  3 - Should we make libcurl able to "walk through" these options in case of
+      (path related) failures, or should it fail and let the user redo any
+      possible retries?
+
+  (This option is not documented in any man page just yet since I'm not sure
+  these names will be used or if the functionality will end up exactly like
+  this.  And for the same reasons we have no test cases for these yet.)
+
+Daniel (10 January 2006)
+- When using a bad path over FTP, as in when libcurl couldn't CWD into all
+  given subdirs, libcurl would still "remember" the full path as if it is the
+  current directory libcurl is in so that the next curl_easy_perform() would
+  get really confused if it tried the same path again - as it would not issue
+  any CWD commands at all, assuming it is already in the "proper" dir.
+
+  Starting now, a failed CWD command sets a flag that prevents the path to be
+  "remembered" after returning.
+
+Daniel (7 January 2006)
+- Michael Jahn fixed so that the second CONNECT when doing FTP over a HTTP
+  proxy actually used a new connection and not sent the second request on the
+  first socket!
+
+Daniel (6 January 2006)
+- Alexander Lazic made the buildconf run the buildconf in the ares dir if that
+  is present instead of trying to mimic that script in curl's buildconf
+  script.
+
+Daniel (3 January 2006)
+- Andres Garcia made the TFTP test server build with mingw.
+
+Daniel (16 December 2005)
+- Jean Jacques Drouin pointed out that you could only have a user name or
+  password of 127 bytes or less embedded in a URL, where actually the code
+  uses a 255 byte buffer for it! Modified now to use the full buffer size.
+
+Daniel (12 December 2005)
+- Dov Murik corrected the HTTP_ONLY define to disable the TFTP support properly
+
+Version 7.15.1 (7 December 2005)
+
+Daniel (6 December 2005)
+- Full text here: http://curl.haxx.se/docs/adv_20051207.html Pointed out by
+  Stefan Esser.
+
+  VULNERABILITY
+
+  libcurl's URL parser function can overflow a malloced buffer in two ways, if
+  given a too long URL.
+
+  These overflows happen if you
+ 
+  1 - pass in a URL with no protocol (like "http://") prefix, using no slash
+      and the string is 256 bytes or longer. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  2 - pass in a URL with only a question mark as separator (no slash) between
+      the host and the query part of the URL. This leads to a single zero byte
+      overflow of the malloced buffer.
+
+  Both overflows can be made with the same input string, leading to two single
+  zero byte overwrites.
+
+  The affected flaw cannot be triggered by a redirect, but the long URL must
+  be passed in "directly" to libcurl. It makes this a "local" problem. Of
+  course, lots of programs may still pass in user-provided URLs to libcurl
+  without doing much syntax checking of their own, allowing a user to exploit
+  this vulnerability.
+
+  There is no known exploit at the time of this writing.
+
+
+Daniel (2 December 2005)
+- Jamie Newton pointed out that libcurl's file:// code would close() a zero
+  file descriptor if given a non-existing file.
+
+Daniel (24 November 2005)
+- Doug Kaufman provided a set of patches to make curl build fine on DJGPP
+  again using configure.
+
+- Yang Tse provided a whole series of patches to clear up compiler warnings on
+  MSVC 6.
+
+Daniel (17 November 2005)
+- I extended a patch from David Shaw to make libcurl _always_ provide an error
+  string in the given error buffer to address the flaw mention on 21 sep 2005.
+
+Daniel (16 November 2005)
+- Applied Albert Chin's patch that makes the libcurl.pc pkgconfig file get
+  installed on 'make install' time.
+
+Daniel (14 November 2005)
+- Quagmire reported that he needed to raise a NTLM buffer for SSPI to work
+  properly for a case, and so we did. We raised it even for non-SSPI builds
+  but it should not do any harm. http://curl.haxx.se/bug/view.cgi?id=1356715
+
+- Jan Kunder's debian bug report
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338680 identified a weird
+  error message for when you try to upload a file and the requested directory
+  doesn't exist on the target server.
+
+- Yang Tse fixed compiler warnings in lib/ssluse.c with OpenSSL 0.9.8 and in
+  lib/memdebug.h that showed up in his msvc builds.
+
+Daniel (13 November 2005)
+- Debian bug report 338681 by Jan Kunder: make curl better detect and report
+  bad limit-rate units:
+  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338681 Now curl will return
+  error if a bad unit is used.
+
+- Thanks to this nice summary of poll() implementations:
+  http://www.greenend.org.uk/rjk/2001/06/poll.html and further tests by Eugene
+  Kotlyarov, we now know that cygwin's poll returns only POLLHUP on remote
+  connectin closure so we check for that case (too) and re-enable poll for
+  cygwin builds.
+
+Daniel (12 November 2005)
+- Eugene Kotlyarov found out that cygwin's poll() function isn't doing things
+  right: http://curl.haxx.se/mail/archive-2005-11/0045.html so we now disable
+  poll() and use select() on cygwin too (we already do the same choice on Mac
+  OS X)
+
+- Dima Barsky patched problem #1348930: the GnuTLS code completely ignored
+  client certificates! (http://curl.haxx.se/bug/view.cgi?id=1348930).
+
+Daniel (10 November 2005)
+- David Lang fixed IPv6 support for TFTP!
+
+- Introducing range stepping to the curl globbing support. Now you can specify
+  step counter by adding :[num] within the brackets when specifying a range:
+
+   [1-100:10]
+   [a-z:2]
+
+  If no step counter is set, it defaults to 1 as before:
+
+   [1-100]
+   [d-h]
+
+Daniel (8 November 2005)
+- Removed the use of AI_CANONNAME in the IPv6-enabled resolver functions since
+  we really have no use for reverse lookups of the address.
+
+  I truly hope these are the last reverse lookups we had lingering in the
+  code!
+
+- Dmitry Bartsevich discovered some issues in compatibilty of SSPI-enabled
+  version of libcurl with different Windows versions. Current version of
+  libcurl imports SSPI functions from secur32.dll. However, under Windows NT
+  4.0 these functions are located in security.dll, under Windows 9x - in
+  secur32.dll and Windows 2000 and XP contains both these DLLs (security.dll
+  just forwards calls to secur32.dll).
+
+  Dmitry's patch loads proper library dynamically depending on Windows
+  version. Function InitSecurityInterface() is used to obtain pointers to all
+  of SSPI function in one structure.
+
+Daniel (31 October 2005)
+- Vilmos Nebehaj improved libcurl's LDAP abilities:
+
+  The LDAP code in libcurl can't handle LDAP servers of LDAPv3 nor binary
+  attributes in LDAP objects. So, I made a quick patch to address these
+  problems.
+
+  The solution is simple: if we connect to an LDAP server, first try LDAPv3
+  (which is the preferred protocol as of now) and then fall back to LDAPv2.
+  In case of binary attributes, we first convert them to base64, just like the
+  openldap client does. It uses ldap_get_values_len() instead of
+  ldap_get_values() to be able to retrieve binary attributes correctly. I
+  defined the necessary LDAP macros in lib/ldap.c to be able to compile
+  libcurl without the presence of libldap
+
+Daniel (27 October 2005)
+- Nis Jorgensen filed bug report #1338648
+  (http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
+  feature request, but anyway. It pointed out that --max-redirs did not allow
+  it to be set to 0, which then would return an error code on the first
+  Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
+  set to 0, or -1 for infinity. Added test case 274 to verify.
+
+- tommink[at]post.pl reported in bug report #1337723
+  (http://curl.haxx.se/bug/view.cgi?id=1337723) that curl could not upload
+  binary data from stdin on Windows if the data contained control-Z (hex 1a)
+  since that is treated as end-of-file when read in text mode. Gisle Vanem
+  pointed out the fix, and I made both -T and --data-binary take advantage of
+  it.
+
+- Jaz Fresh pointed out that if you used "-r [number]" as was wrongly described
+  in the man page, curl would send an invalid HTTP Range: header. The correct
+  way would be to use "-r [number]-" or even "-r -[number]". Starting now,
+  curl will warn if this is discovered, and automatically append a dash to the
+  range before passing it to libcurl.
+
+Daniel (25 October 2005)
+- Amol Pattekar reported a bug with great detail and a fine example in bug
+  #1326306 (http://curl.haxx.se/bug/view.cgi?id=1326306). When using the multi
+  interface and connecting to a host with multiple IP addresses, and one of
+  the addresses fails to connect (the server must exist and respond, just not
+  accept connections) libcurl leaks a socket descriptor. Thanks to the fine
+  report, I could find and fix this.
+
+Daniel (22 October 2005)
+- Dima Barsky reported a problem with GnuTLS-enabled libcurl in bug report
+  #1334338 (http://curl.haxx.se/bug/view.cgi?id=1334338). When reading an SSL
+  stream from a server and the server requests a "rehandshake", the current
+  code simply returns this as an error. I have no good way to test this, but
+  I've added a crude attempt of dealing with this situation slightly better -
+  it makes a blocking handshake if this happens. Done like this because fixing
+  this the "proper" way (that would handshake asynchronously) will require
+  quite some work and I really need a good way to test this to do such a
+  change.
+
+Daniel (21 October 2005)
+- "Ofer" reported a problem when libcurl re-used a connection and failed to do
+  it, it could then accidentally actually crash. Presumably, this concerns FTP
+  connections.  http://curl.haxx.se/bug/view.cgi?id=1330310
+
+- Temprimus improved the MSVC makefile so that the static debug SSL libs are
+  linked to the executable and not to the libcurld.lib
+  http://curl.haxx.se/bug/view.cgi?id=1326676
+
+- Bradford Bruce made the windows resolver code properly return
+  CURLE_COULDNT_RESOLVE_PROXY and CURLE_COULDNT_RESOLVE_HOST on resolving
+  errors (as documented).
+
+Daniel (20 October 2005)
+- Dave Dribin made libcurl understand and handle cases when the server
+  (wrongly) sends *two* WWW-Authenticate headers for Digest. While this should
+  never happen in a sane world, libcurl previously got into an infinite loop
+  when this occurred. Dave added test 273 to verify this.
+
+- Temprimus improved the MSVC makefile: "makes a build option available so if
+  you set rtlibcfg=static for the make, then it would build with /MT. The
+  default behaviour is /MD (the original)."
+  http://curl.haxx.se/bug/view.cgi?id=1326665
+
+Daniel (14 October 2005)
+- Reverted the LIBCURL_VERSION_NUM change from October 6. As Dave Dribin
+  reported, the define is used by the configure script and is assumed to use
+  the 0xYYXXZZ format. This made "curl-config --vernum" fail in the 7.15.0
+  release version.

- o -z over FTP now considers equal timestamps "not modified since"
- o Weird characters removed from the configure script
- o Fixed time zone offsets for MEST and CEST for the time parser
- o HTTP Content-Range header parser crash
- o FTPS negotiation timeouts/errors
- o SSPI works even for Windows 9x
- o crash in --dump-header on FTP
- o test 56 runs better
+ o TFTP Packet Buffer Overflow Vulnerability:
+   http://curl.haxx.se/docs/adv_20060320.html
+ o properly detecting problems with sending the FTP command USER
+ o wrong error message shown when certificate verification failed

 Other curl-related news since the previous public release:
 
- o http://curl.freemirror.de/ is a new German mirror
- o All curl relatd mailing list information and subscribers on cool.haxx.se
-   were lost due to a malicious user exploiting a security hole on the
-   server. Attempts have been made to put back susbcribers on the lists, but
-   many have been lost: http://curl.haxx.se/mail/lost.html

 This release would not have looked like this without help, code, reports and
 advice from friends like these:

   Changelog for the c-ares project
 
+* January 9, 2006
+
+- Alexander Lazic improved the getservbyport_r() configure check.
+
+* January 6, 2006
+
+- Alexander Lazic pointed out that the buildconf should use the ACLOCAL_FLAGS
+  variable for easier controlling what it does and how it runs.
+
+* January 5, 2006
+
+- James Bursa fixed c-ares to find the hosts file on RISC OS, and made it
+  build with newer gcc versions that no longer defines "riscos".
+
+* December 22
+
+- Daniel Stenberg added ares_getsock() that extracts the set of sockets to
+  wait for action on. Similar to ares_fds() but not restricted to using
+  select() for the waiting.
+
+* November 25
+
+- Yang Tse fixed some send() / recv() compiler warnings
+
 * September 18
 
 - Added constants that will be used by ares_getaddrinfo

+.SH NAME
+ares_getsock \- get file descriptors to wait on
+.SH SYNOPSIS
+.nf
+.B #include <ares.h>
+.PP
+.B int ares_getsock(ares_channel \fIchannel\fP, int *\fIsocks\fP, 
+.B int \fInumsocks\fP);
+.fi
+.SH DESCRIPTION
+The
+.B ares_getsock
+function retrieves the set of file descriptors which the calling
+application should wait on for reading and/or writing for the
+processing of name service queries pending on the name service channel
+identified by
+.IR channel .
+File descriptors will be set in the integer array pointed to by
+\fIsocks\fP.
+\fInumsocks\fP is the size of the given array in number of ints.
+
+This function can only return information about up to 16 sockets. If more are
+in use (however unlikely that is), they are simply not reported back.
+.SH RETURN VALUES
+\fBares_getsock\fP returns a bitmask for what actions to wait for on the
+different sockets. The ares.h header file provides these convenience macros to
+extract the information appropriately:
+
+.nf
+#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
+                                  this many sockets */
+#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
+#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \
+                                         ARES_GETSOCK_MAXNUM)))
+.fi
+.SH NOTES
+This function was added in c-ares 1.3.1
+.SH SEE ALSO
+.BR ares_timeout (3),
+.BR ares_fds (3),
+.BR ares_process (3)

+
+  Libcurl Install and Use Issues
+  Awaiting an Answer for Win 32 Install 
+  res = curl_easy_perform(curl); Error
+  Makefile Issues
+  
+
+Having previously done a thorough review of what was available that met my
+requirements under GPL, I settled for Libcurl as the software of choice for
+many reasons not the least of which was the support.
+
+Background
+----------
+
+This quest started when I innocently tried to incorporate the libcurl library
+into my simple source code. I figured that a few easy steps would accomplish
+this without major headaches. I had no idea that I would be facing an almost
+insurmountable challenge.
+
+The main problem lies in two areas. First the bulk of support for libcurl
+exists for a Unix/linux command line environments. This is of little help when
+it comes to Windows O/S.
+
+Secondly the help that does exist for the Windows O/S focused around mingw
+thru a command line argument environment.
+
+You may ask "Why is this a problem?"
+
+I'm using a Windows O/S with DevCpp. For those of you who are unfamiliar with
+DevCpp, it is a window shell GUI that replaces the command line environment
+for gcc. A definite improvement that I am unwilling to give up. However using
+DevCpp presented its own set of issues. Inadvertently I also made some
+careless errors such as compiling the 7.14 version of Makefile with an older
+version of source code. Thanks to Dan Fandrich for picking this up.
+
+I did eventually with the help of Daniel, Phillipe and others manage to
+implement successfully (the only mingw available version)
+curl-7.13.0-win32-ssl-devel-mingw32 into the DevCpp environment. Only the
+dynamic libcurl.dll libcurldll.a libraries worked. The static library which I
+was interested in did not. Furthermore when I tried to implement one of the
+examples included with the curl package (get info.c) it caused the executable
+to crash. Tracing the bug I found it in the code and function res =
+curl_easy_perform(curl);.
+
+At this point I had to make a choice as to whether invest my limited
+time-energy resource to fixing the bug or to compile the new version
+available. After searching the archives I found a very similar or the same bug
+reported from version 7.12x on. Daniel did inform me that he thought that this
+bug had been fixed with the latest version. So I proceeded to compile the
+latest SSL version where I faced other challenges.
+
+In order to make this process unremarkable for others using the same
+environment I decided to document the process so that others will find it
+routine. It would be a shame if newbies could not implement this excellent
+package for their use.
+
+I would like to thank the many others in this forum and in the DevCpp forum
+for their help. Without your help I may either have given up or it would have
+taken me many times longer to achieve success.
+
+The Cookbook Approach
+---------------------
+
+This discussion will be confined to a SSL static library compilation and
+installation. Limited mention and comments will be inserted where appropriate
+to help with non-SSL, dynamic libraries and executables.
+
+
+   Using Makefile from DevCpp to compile Libcurl libraries
+
+Preamble
+--------
+
+Using the latest version release - curl-7.14.0.tar.gz. Curl source code is
+platform independent. This simply means that the source code can be compiled
+for any Operating System (Linux/Unix Windows etc. and variations of thereof).
+
+The first thing to note is that inside curl-7.14.0 you will find two folders
+lib and src. Both contain Makefile.m32 (required for win mingw library or exe
+compilation) files which are different. The main difference between these two
+folders and the makefiles is that the src folder contents are used to compile
+an executable file(curl.exe) while the lib folder contents are used to compile
+a static (libcurl.a) and dynamic (libcurl.dll & libcurldll.a) file that can be
+used to compile libcurl with your own source code so that one can use and
+access all libcurl functions.
+
+Before we start please make sure that DevCpp is installed properly. In
+particular make sure you have no spaces in the name of any of the directories
+and subdirectories where DevCpp is installed. Failure to comply with the
+install instructions may produce erratic behaviour in DevCpp. For further info
+check the following sites
+
+http://aditsu.freeunixhost.com/dev-cpp-faq.html
+http://sourceforge.net/forum/message.php?msg_id=3252213
+
+As I have mentioned before I will confine this to the SSL Library compilations
+but the process is very similar for compilation of the executable - curl.exe;
+just substitute the src folder makefile in its stead.
+
+First use a text processor Notepad, or your own favourite text processor. To
+engage your favourite text processor, select Makefile.m32 click once with your
+mouse on file icon; icon turns blue, press the shift key and right-click on
+mouse, menu appears select "Open with", select your favourite text processor.
+
+Next read the contents of Makefile.m32. It includes instructions on its use.
+
+Method I - DOS Command Line
+---------------------------
+ 
+Note - The only reason I have included this method is that Method II which is
+the preferred method for compiling does not allow for the setting of option
+switches (e.g. SSL = 1 or SSL =0). At least that's what they tell me at the
+Dev-Cpp forum.
+
+1 - Make a copy of (D:\Dev-Cpp\bin) bin folder and name it "bin Original"
+place it in the Dev-Cpp installed directory (D:\Dev-Cpp\ for this example)
+
+2 - Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into the bin folder above (D:\Dev-Cpp\bin). The reason being is that
+the make.exe file resides in this folder. Make.exe will use - Makefile.m32,
+Makefile.inc, and the source code included in the lib folder to compile the
+source code. There is a PATH issue with make.exe that remains unresolved at
+least for me. Unless the entire source code to be compiled is placed entirely
+within the directory of make.exe an error message will be generated - "file
+xxxx.yyy not available".
+
+3- Go to Dev-Cpp\bin and double click on make .exe. You will see a DOS window
+quickly pop up and close very quickly. Not to worry! Please do not skip this
+step.
+
+4- Click on the start button\Programs\MS-DOS Prompt.Once the DOS Window is up
+Type the disk drive letter (e.g. E: ) engage the enter button. The path should
+automatically take you to the directory of the make.exe file.
+
+5- To compile the source code simply type at the DOS prompt make -f
+Makefile.m32 as per instructions contained in the Makefile.m32 file (use any
+text processor to read instructions). I don't believe that this makefile
+allows for the option of non SSL. Ignore any warnings.
+
+6- Collect and make copies of libcurl.a, libcurl.dll, libcurldll.a and any *.o
+compilations you might need in another directory outside of the bin directory
+as you will need this files shortly to set up libcurl for use with
+Dev-cpp. For most apps *.o is not required. Later on we will show what to do
+with these files.
+
+7- You are finished but before closing we need to do cleanup - erase the bin
+folder and rename the "bin Original" folder created in step 1 to bin.
+
+Note to compile a curl executable the process is probably similar but instead
+of using the LIB folder contents use the SRC folder contents and Makefiles in
+curl-7.14.0.tar.gz. File directories relative placements must be respected for
+compiling to take place successfully. This may not be possible with the PATH
+problem that make.exe experiences. If anyone has solved this PATH issue and
+please make sure it actually works on Win 9x/2000/XP before letting me
+know. Then please let me or Daniel in on the solution so that it can be
+included with these instructions. Thanks.
+
+or
+
+Method II - Dev-Cpp GUI
+-----------------------
+
+1- Copy the entire contents of the LIB folder of curl-7.14.0.tar.gz or zip
+version into any folder outside of (Dev-Cpp\bin).
+
+2- Drop the File/New/click on Project.
+
+3- New Project Dialogue box appears. Double click on the Static Library.
+
+4- Create Project Dialogue box appears. Select the LIB folder location to
+place and locate your Project File Name. Placing the Project File Name
+elsewhere may cause problems (PATH issue problem again).
+
+5- Drop down the Project/Project Options. Project Options Dialogue box
+appears.
+
+6- Select the Makefile tab in the Project Options Dialogue Box. Check Box -
+Use Custom Makefile. Click on the Folder icon at the extreme right of the
+Check Box. Select Makefile.m32 in the folder wherever you have placed the
+contents of the LIB Folder. Press OK and close the Dialogue Box.
+
+7- Drop the Menu Project/Click on Add to Project. Open File Dialogue Box
+appears.  The Dialogue Box should open in the folder wherever you have placed
+the contents of the LIB Folder. If not go there.
+
+8- Select Crtl-A to select all files in the LIB folder. Click on open to add
+files and close box. Wait till all files are added. This may take 30 seconds
+or longer.
+
+9- Drop the Menu Execute/Click on Compile. 
+
+10- That's it.
+
+
+   The following steps must be completed if Curl is to work properly
+   =================================================================
+
+LIB folder inclusions (*.a placement)
+-------------------------------------
+
+1- Refer to Method I - DOS Command Line point # 6 Take libcurl.a, libcurldll.a
+and install it in the directory C( or whichever drive Dev is installed)
+:\Dev-Cpp\lib.
+
+
+Include Folder
+--------------
+
+1- Create a new folder by the name of curl (do not change the name curl to
+some other name as it will cause major issues) in the directory
+C:\Dev-Cpp\include.
+
+2- Copy the entire contents of the curl folder of curl-7.14.0.tar.gz or zip
+ version into the newly created curl directory - C:\Dev-Cpp\include\curl.
+
+Links To Include And Lib Folder
+-------------------------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Libraries. Make sure
+that C( or whichever drive Dev is installed):\DEV-CPP\lib is included.
+
+2- Next select the Menu - Tools\Compiler Options\Directories\C Includes. Make
+sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are included.
+
+3- Next select the Menu - Tools\Compiler Options\Directories\C++
+Includes. Make sure that C:\DEV-CPP\include and C:\Dev-Cpp\include\curl are
+included.
+
+Linker Links
+------------
+
+1- Drop the Menu - Tools\Compiler Options\Directories\Compiler.
+
+2- Make sure that the box "Add these commands to the linker command line" is
+checked.
+
+3- Include in the white space immediately below the box referred in 2 -lcurl
+-lws2_32 -lwinmm.
+
+SSL Files
+---------
+
+1- Get the latest openSSL (as of time of this writing)
+openssl-0.9.7e-win32-bin.zip for the minimalist package of the openssl-0.9.7e
+binaries ported to MS Windows 95/98/NT/XP using the MingW32/GCC-3.1
+development environment. The file may be downloaded at
+http://curl.haxx.se/download/.
+
+2- Open the above zip file. You will find two files - SDL.dll,
+SDL_mixer.dll. Install them in the directory C:\WINDOWS\SYSTEM32 for Win 9x
+users and c:\winnt\system32 for NT-family users.
+
+Multithreading Files
+--------------------
+
+To be completed
+
+#define
+-------
+
+1- Make sure that your program includes the following - #define CURL_STATICLIB
+must be declared FIRST before any other define functions may be
+added. Otherwise you may experience link errors.
+
+2- Don't forget to include   #include "curl/curl.h".
+
+e.g.
+    #define CURL_STATICLIB 
+#include <windows.h>
+    #include "curl/curl.h"
+#include <fstream>
+#include <iostream>
+#include <vector>
+etc...
+
+
+Static or Dynamic Library
+-------------------------
+
+The above steps apply for the use by a static library. Should you choose to
+use a dynamic library you will be required to perform these additional steps.
+
+1- Refer to Method I - DOS Command Line point # 6. Install libcurl.dll in the
+directory C:\WINDOWS\SYSTEM32 for Win 9x users and c:\winnt\system32 for
+NT-family users.
+
+2- Refer to Linker Links point 3 - Replace -lcurl with -lcurldll.
+
+Voila you're done.
+
+The non-SSL static Library build may not be possible to use at least as of the
+time of this writing - v7.14. Check reference emails - Phillipe and I found it
+impossible to fully compile as certain files were missing for linking. No big
+loss as SSL is a major plus.
+
+Hope this Helps

+ * This example code only builds as-is on Windows.
+ *
+ * Synchronising your computer clock via Internet time server usually relies
+ * on DAYTIME, TIME, or NTP protocols. These protocols provide good accurate
+ * time synchronisation but it does not work very well through a
+ * firewall/proxy. Some adjustment has to be made to the firewall/proxy for
+ * these protocols to work properly.
+ *
+ * There is an indirect method. Since most webserver provide server time in
+ * their HTTP header, therefore you could synchronise your computer clock
+ * using HTTP protocol which has no problem with firewall/proxy.
+ *
+ * For this software to work, you should take note of these items.
+ * 1. Your firewall/proxy must allow your computer to surf internet.
+ * 2. Webserver system time must in sync with the NTP time server,
+ *    or at least provide an accurate time keeping.
+ * 3. Webserver HTTP header does not provide the milliseconds units,
+ *    so there is no way to get very accurate time.
+ * 4. This software could only provide an accuracy of +- a few seconds,
+ *    as Round-Trip delay time is not taken into consideration.
+ *    Compensation of network, firewall/proxy delay cannot be simply divide
+ *    the Round-Trip delay time by half.
+ * 5. Win32 SetSystemTime() API will set your computer clock according to
+ *    GMT/UTC time. Therefore your computer timezone must be properly set.
+ * 6. Webserver data should not be cached by the proxy server. Some
+ *    webserver provide Cache-Control to prevent caching.
+ *
+ * References:
+ * http://tf.nist.gov/timefreq/service/its.htm

+ * it with --synctime. By default, it only display the webserver's clock.

+.SH SYNOPSIS

+
+CURLMcode curl_multi_setopt(CURLM * multi_handle, CURLMoption option, param);
+.SH DESCRIPTION
+curl_multi_setopt() is used to tell a libcurl multi handle how to behave. By
+using the appropriate options to \fIcurl_multi_setopt\fP, you can change
+libcurl's behaviour when using that multi handle.  All options are set with
+the \fIoption\fP followed by the parameter \fIparam\fP. That parameter can be
+a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject pointer\fP or a
+\fBcurl_off_t\fP type, depending on what the specific option expects. Read
+this manual carefully as bad input values may cause libcurl to behave badly!
+You can only set one option in each function call.
+
+.SH OPTIONS
+.IP CURLMOPT_SOCKETFUNCTION
+Pass a pointer to a function matching the curl_socket_callback prototype. The
+\fIcurl_multi_socket(3)\fP functions inform the application about updates in
+the socket (file descriptor) status by doing none, one or multiple calls to
+the curl_socket_callback given in the \fBparam\fP argument. They update the
+status with changes since the previous time a \fIcurl_multi_socket(3)\fP
+function was called. If the given callback pointer is NULL, no callback will
+be called. Set the callback's fourth argument with \fICURLMOPT_SOCKETDATA\fP.
+See \fIcurl_multi_socket(3)\fP for more callback details.
+.IP CURLMOPT_SOCKETDATA
+Pass a pointer to whatever you want passed to the curl_socket_callback's forth
+argument, the userp pointer. This is not used by libcurl but only passed-thru
+as-is. Set the callback pointer with \fICURLMOPT_SOCKETFUNCTION\fP.

+CURLMcode curl_multi_socket(CURLM * multi_handle, curl_socket_t sockfd);
+
+CURLMcode curl_multi_socket_all(CURLM *multi_handle);
+.SH DESCRIPTION
+Alternative versions of \fIcurl_multi_perform()\fP that allows the application
+to pass in one of the file descriptors/sockets that have been detected to have
+\&"action" on them and let libcurl perform. This allows libcurl to not have to
+scan through all possible file descriptors to check for action. When the
+application has detected action on a socket handled by libcurl, it should call
+\fIcurl_multi_perform()\fP with the \fBsockfd\fP argument set to the socket
+with the action.
+
+These functions inform the application about updates in the socket (file
+descriptor) status by doing none, one or multiple calls to the
+curl_socket_callback given with the CURLMOPT_SOCKETFUNCTION option to
+\fIcurl_multi_setopt(3)\fP. They update the status with changes since the
+previous time this function was called.
+
+If you want to force libcurl to (re-)check all its internal sockets and
+transfers instead of just a single one, you call
+\fBcurl_multi_socket_all(3)\fP instead.
+
+An application should call \fBcurl_multi_timeout(3)\fP to figure out how long
+it should wait for socket actions \- at most \- before doing the timeout
+action: call the \fBcurl_multi_socket(3)\fP function with the \fBsockfd\fP
+argument set to CURL_SOCKET_TIMEOUT.
+
+The socket \fBcallback\fP function uses a prototype like this
+.nf
+
+     int curl_socket_callback(CURL *easy,      /* easy handle */
+                              curl_socket_t s, /* socket */
+                              int action,      /* see values below */
+                              void *userp);    /* "private" pointer */
+
+.fi
+The callback MUST return 0.
+
+The \fIaction\fP (third) argument to the callback has one of five values:
+.RS
+.IP "CURL_POLL_NONE (0)"
+register, not interested in readiness (yet)
+.IP "CURL_POLL_IN (1)"

+.RE
+.SH "RETURN VALUE"
+CURLMcode type, general libcurl multi interface error code.
+
+If you receive \fICURLM_CALL_MULTI_PERFORM\fP, this basically means that you
+should call \fIcurl_multi_perform\fP again, before you wait for more actions
+on libcurl's sockets. You don't have to do it immediately, but the return code
+means that libcurl may have more data available to return or that there may be
+more data to send off before it is "satisfied".
+

+
+.SH "GLOBAL CONSTANTS"
+There are a variety of constants that libcurl uses, mainly through its
+internal use of other libraries, which are too complicated for the
+library loader to set up.  Therefore, a program must call a library
+function after the program is loaded and running to finish setting up
+the library code.  For example, when libcurl is built for SSL
+capability via the GNU TLS library, there is an elaborate tree inside
+that library that describes the SSL protocol.
+
+\fIcurl_global_init()\fP is the function that you must call.  This may
+allocate resources (e.g. the memory for the GNU TLS tree mentioned
+above), so the companion function \fIcurl_global_cleanup()\fP releases
+them.
+
+The basic rule for constructing a program that uses libcurl is this:
+Call \fIcurl_global_init()\fP, with a \fICURL_GLOBAL_ALL\fP argument,
+immediately after the program starts, while it is still only one
+thread and before it uses libcurl at all.  Call
+\fIcurl_global_cleanup()\fP immediately before the program exits, when
+the program is again only one thread and after its last use of
+libcurl.
+
+You can call both of these multiple times, as long as all calls meet
+these requirements and the number of calls to each is the same.
+
+It isn't actually required that the functions be called at the beginning
+and end of the program -- that's just usually the easiest way to do it.
+It \fIis\fP required that the functions be called when no other thread
+in the program is running.
+
+These global constant functions are \fInot thread safe\fP, so you must
+not call them when any other thread in the program is running.  It
+isn't good enough that no other thread is using libcurl at the time,
+because these functions internally call similar functions of other
+libraries, and those functions are similarly thread-unsafe.  You can't
+generally know what these libraries are, or whether other threads are
+using them.
+
+The global constant situation merits special consideration when the
+code you are writing to use libcurl is not the main program, but rather
+a modular piece of a program, e.g. another library.  As a module,
+your code doesn't know about other parts of the program -- it doesn't
+know whether they use libcurl or not.  And its code doesn't necessarily
+run at the start and end of the whole program.
+
+A module like this must have global constant functions of its own,
+just like \fIcurl_global_init()\fP and \fIcurl_global_cleanup()\fP.
+The module thus has control at the beginning and end of the program
+and has a place to call the libcurl functions.  Note that if multiple
+modules in the program use libcurl, they all will separately call the
+libcurl functions, and that's OK because only the first
+\fIcurl_global_init()\fP and the last \fIcurl_global_cleanup()\fP in a
+program changes anything.  (libcurl uses a reference count in static
+memory).
+
+In a C++ module, it is common to deal with the global constant
+situation by defining a special class that represents the global
+constant environment of the module.  A program always has exactly one
+object of the class, in static storage.  That way, the program
+automatically calls the constructor of the object as the program
+starts up and the destructor as it terminates.  As the author of this
+libcurl-using module, you can make the constructor call
+\fIcurl_global_init()\fP and the destructor call
+\fIcurl_global_cleanup()\fP and satisfy libcurl's requirements without
+your user having to think about it.
+
+\fIcurl_global_init()\fP has an argument that tells what particular
+parts of the global constant environment to set up.  In order to
+successfully use any value except \fICURL_GLOBAL_ALL\fP (which says to
+set up the whole thing), you must have specific knowledge of internal
+workings of libcurl and all other parts of the program of which it is
+part.
+
+A special part of the global constant environment is the identity of
+the memory allocator.  \fIcurl_global_init()\fP selects the system
+default memory allocator, but you can use \fIcurl_global_init_mem()\fP
+to supply one of your own.  However, there is no way to use
+\fIcurl_global_init_mem()\fP in a modular program -- all modules in
+the program that might use libcurl would have to agree on one
+allocator.
+
+There is a failsafe in libcurl that makes it usable in simple
+situations without you having to worry about the global constant
+environment at all: \fIcurl_easy_init()\fP sets up the environment
+itself if it hasn't been done yet.  The resources it acquires to do so
+get released by the operating system automatically when the program
+exits.
+
+This failsafe feature exists mainly for backward compatibility because
+there was a time when the global functions didn't exist.  Because it
+is sufficient only in the simplest of programs, it is not recommended
+for any program to rely on it.

+
+       Status of project Hiper - high performance libcurl modifications
+       ================================================================
+
+What is Hiper
+
+  You won't find such a description in this document. See
+  http://curl.haxx.se/libcurl/hiper/ for further details.
+
+Live Progress Info
+
+  During my work, I've posted occational updates on the curl-library mailing
+  list but more importantly done frequent updates of
+  http://curl.haxx.se/libcurl/hiper/schedule.html
+
+Schedule
+
+  I took time off my regular job during Decemember 2005 and the first week of
+  January 2006 to work on hiper full-time.
+
+Step 1 - Measure the Existing Solution
+
+  I started full-time work on project Hiper on December 1st 2005. I began by
+  putting together a test application that used the existing API to allow me
+  to properly and with accuracy measure execution and transfer speeds when
+  doing a large amount of transfers.
+
+  I soon discovered that it was impossible to do any sensible measurements by
+  using live and actual URLs since the transfers were too unrelialble and
+  uncontrolled. I then enhanced the current HTTP server in the curl test suite
+  and made that support a large amount of transfers and some extra magic
+  "commands" that would make the server either just sit "idle" or "stream"
+  (continuously sending data in a never-ending stream). I then wrote up two
+  files using the curl test suite file format and by acessing the properly
+  formatted URLs on my localhost the HTTP server would either run "idle" or
+  run "stream".
+
+  Having this working, I patched libcurl to always only recv() a single byte
+  off the network each time, just to make sure that the time spent on reading
+  data is constant and never very long.
+
+  I adjusted the test application (actually called 'hiper') to create Y idle
+  transfers and Z stream transfers, had it run for N seconds and then quit and
+  produce a summary on stdout. Now I got very solid and repeatable results. I
+  started to run repeated tests and save the results when I ran into the
+  dreaded 1024 socket maximum limit.
+
+  One side of the problem is that the fd_set type only allows 1024 file
+  descriptors (on my Linux), which I had to solve by simply making my own type
+  with room for more connections and do ugly typecasts in the code. The other
+  side of the problem is that user applications have a limit imposed by the
+  system on the maximum amount of file descriptors it can have open and I had
+  to work around that by writing a special tool that runs setuid root that
+  increases the limit, downgrades to a normal user again and then run the
+  command line of your choice. This second approach has to be used for both
+  'hiper' and the test HTTP server. (You need to build the HTTP server with
+  CURL_SWS_FORK_ENABLED defined to have it do forks since it isn't desirable
+  to do so when running the normal curl tests.)
+
+  Now I could run my test program without problems. I decided to run the tests
+  with 1 stream connection and a varying amount of idle ones. I did 1001,
+  2001, 3001, 5001 and 9001 connections and measured how long select() and
+  curl_multi_perform() (including the curl_multi_fdset() call) would take in
+  average, over a period of 20 seconds. I ran each test 5-6 times and I used
+  the average time of all the runs.
+
+  The times in number of microseconds:
+
+    Connections  multi_perform  select
+    1001         3504           951
+    2001         7606           1988
+    3001         11045          2715
+    5001         16406          4024
+    9001         32147          8030
+
+  Test system
+    CPU:     Athlon XP 2800 
+    RAM:     1 GB
+    Linux:   2.6
+    glibc:   2.3.5
+    libcurl: 7.15.1
+
+  The only reason I stopped at 9001 connections is that my test machine ran
+  out of avaiable memory by then as I ran the test server on the same machine,
+  and I didn't want to risk the test result accuracy by having it start using
+  the swap during the tests.
+
+  It means that at 9000 connections we spend 40ms for each socket action, even
+  when only one socket ever have action.
+
+  With these 32000 microseconds curl_multi_perform() takes for 9000
+  connections, it loops 18000 laps which makes less than 2 microseconds per
+  lap. (Of course counting time/laps is an oversimplification, but anyway.)
+  Hopefully we should achieve less than 10 microseconds for each call to
+  curl_multi_socket() for an active connection.
+
+  The timing graph displayed on the libevent site (duplicated on the hiper
+  project page) suggests that libevent is pretty much fixed at 50 microseconds
+  (although I don't know what test box was used in their testing, we can
+  compare the select()-times from my tests and see that they are at least
+  resonably close).
+
+  Summing up, the current ~40 ms spent at 9000 connections could then possibly
+  be lowered to something around 60 us!
+
+Step 2 - Implement curl_multi_socket API
+
+  Most of the design decisions and debates about this new API have already
+  been held on the curl-library mailing list a long time ago so I had a basic
+  idea on what approach to use. The main ideas of the new API are simply:
+
+   1 - The application can use whatever event system it likes as it gets info
+       from libcurl about what file descriptors libcurl waits for what action
+       on. (The previous API returns fd_sets which is very select()-centric).
+
+   2 - When the application discovers action on a single socket, it calls
+       libcurl and informs that there was action on this particular socket and
+       libcurl can then act on that socket/transfer only and not care about
+       any other transfers. (The previous API always had to scan through all
+       the existing transfers.)
+
+  The idea is that curl_multi_socket() calls a given callback with information
+  about what socket to wait for what action on, and the callback only gets
+  called if the status of that socket has changed.
+
+  In the API draft from before, we have a timeout argument on a per socket
+  basis and we also allowed curl_multi_socket() to pass in an 'easy handle'
+  instead of socket to allow libcurl to shortcut a lookup and work on the
+  affected easy handle right away. Both these turned out to be bad ideas.
+
+  The timeout argument was removed from the socket callback since after much
+  thinking I came to the conclusion that we really don't want to handle
+  timeouts on a per socket basis. We need it on a per transfer (easy handle)
+  basis and thus we can't provide it in the callbacks in a nice way. Instead,
+  we have to offer a curl_multi_timeout() that returns the largest amount of
+  time we should wait before we call the "timeout action" of libcurl, to
+  trigger the proper internal timeout action on the affected transfer. To get
+  this to work, I added a struct to each easy handle in which we store an
+  "expire time" (if any). The structs are then "splay sorted" so that we can
+  add and remove times from the linked list and yet somewhat swiftly figure
+  out 1 - how long time there is until the next timer expires and 2 - which
+  timer (handle) should we take care of now. Of course, the upside of all this
+  is that we get a curl_multi_timeout() that should also work with old-style
+  applications that use curl_multi_perform().
+
+  The easy handle argument was removed fom the curl_multi_socket() function
+  because having it there would require the application to do a socket to easy
+  handle conversion on its own. I find it very unlikely that applications
+  would want to do that and since libcurl would need such a lookup on its own
+  anyway since we didn't want to force applications to do that translation
+  code (it would be optional), it seemed like an unnecessary option. I also
+  realized that when we use underlying libraries such as c-ares (for DNS
+  asynch resolving) there might in fact be more than one transfer waiting for
+  action on the same socket and thus it makes the lookup even tricker and even
+  less likely to ever get done by applications. Instead I created an internal
+  "socket to easy handles" hash table that given a socket (file descriptor)
+  returns a list of easy handles that waits for some action on that socket.
+
+  To make libcurl be able to report plain sockets in the socket callback, I
+  had to re-organize the internals of the curl_multi_fdset() etc so that the
+  conversion from sockets to fd_sets for that function is only done in the
+  last step before the data is returned. I also had to extend c-ares to get a
+  function that can return plain sockets, as that library too returned only
+  fd_sets and that is no longer good enough. The changes done to c-ares have
+  been committed and are available in the c-ares CVS repository destined to be
+  included in the upcoming c-ares 1.3.1 release.
+
+  The 'shiper' tool is the test application I wrote that uses the new
+  curl_multi_socket() in its current state. It seems to be working and it uses
+  the API as it is documented and supposed to work. It is still using
+  select(), because I needed that during development (like until I had the
+  socket hash implemented etc) and because I haven't yet learned how to use
+  libevent or similar.
+
+  The hiper/shiper tools are very simple and initiates lots of connections and
+  have them running for the test period and then kills them all.
+
+  Since I wasn't done with the implementation until early January I haven't
+  had time to run very many measurements and checks, but I have done a few
+  runs with up to a few hundred connections (with a single active one). The
+  curl_multi_socket() invoke then takes 3-6 microseconds in average (using the
+  read-only-1-byte-at-a-time hack). If this number does increase a lot when we
+  add connections, it certainly matches my in my opinion very ambitious goal.
+  We are now below the 60 microseconds "per socket action" goal. It is
+  destined to be somewhat higher the more connections we have since the hash
+  table gets more populated and the splay tree will grow etc.
+
+  Some tests at 7000 and 9000 connections showed that the socket hash lookup
+  is somewhat of a bottle neck. Its current implementation may be a bit too
+  limiting. It simply has a fixed-size array, and on each entry in the array
+  it has a linked list with entries. So the hash only checks which list to
+  scan through. The code I had used so for used a list with merely 7 slots (as
+  that is what the DNS hash uses) but with 7000 connections that would make an
+  average of 1000 nodes in each list to run through. I upped that to 97 slots
+  (I believe a prime is suitable) and noticed a significant speed increase.  I
+  need to reconsider the hash implementation or use a rather large default
+  value like this. At 9000 connections I was still below 10us per call.
+
+Status Right Now
+
+  The curl_multi_socket() API is implemented according to how it is
+  documented. The man pages for curl_multi_socket and curl_multi_timeout are
+  both committed to CVS and are available online for easy browsing:
+
+    http://curl.haxx.se/libcurl/c/curl_multi_socket.html
+    http://curl.haxx.se/libcurl/c/curl_multi_timeout.html
+
+  The hiper-5.patch I made available early morning January 5th, 2006 should
+  apply fine on a recent CVS checkout (at the time of this writing curl 7.15.1
+  is the latest public curl release but the hiper patch does not apply fine on
+  that).
+
+What is Left for the curl_multi_socket API
+
+  1 - More measuring with more extreme number of connections
+
+  2 - More testing with actual URLs and complete from start to end transfers.
+
+  I'm quite sure we don't set expire times all over in the code properly, so
+  there is bound to be some timeout bugs left.
+
+  What it really takes is for me to commit the code and to make an official
+  release with it so that we get people "out there" to help out testing it.
+
+What is Left for project Hiper
+
+  1 - Add HTTP pipelining support
+
+  2 - Add a zero (or at least close to zero) copy interface
+
+  Neither of these points have been planned or detailed exactly how they will
+  be implemented.
+
+Roadmap Ahead
+
+  I plan and hope to return to full-time hiper work later on this spring or
+  possibly summer to continue where I pause now. Of course some spare time
+  might also be spent until then to get us moving forward.

  * Desc:    An alternative version of curl_multi_perform() that allows the
  *          application to pass in one of the file descriptors that have been
- *          detected to have "action" on them and let libcurl perform. This
- *          allows libcurl to not have to scan through all possible file
- *          descriptors to check for this. The app is recommended to pass in
- *          the 'easy' argument (or set it to CURL_EASY_NONE) to make libcurl
- *          figure out the internal structure even faster and easier.  If the
- *          easy argument is set to something else than CURL_EASY_NONE, the
- *          's' (socket) argument will be ignored by libcurl.
- *
- *          It also informs the application about updates in the socket (file
- *          descriptor) status by doing none, one or multiple calls to the
- *          curl_socket_callback. It thus updates the status with changes
- *          since the previous time this function was used. If 'callback' is
- *          NULL, no callback will be called. A status change may also be a
- *          new timeout only, having the same IN/OUT status as before.
- *
- *          If a previous wait for socket action(s) timed out, you should call
- *          this function with the socket argument set to
- *          CURL_SOCKET_TIMEOUT. If you want to force libcurl to (re-)check
- *          all its internal sockets, and call the callback with status for
- *          all sockets no matter what the previous state is, you call
- *          curl_multi_socket_all() instead.
- *
- *          curl_multi_perform() is thus the equivalent of calling
- *          curl_multi_socket_all(handle, NULL, NULL);
- *
- *          IMPLEMENTATION: libcurl will need an internal hash table to map
- *          socket numbers to internal easy handles for the cases when 'easy'
- *          is set to CURL_EASY_NONE.
- *
- *          Regarding the timeout argument in the callback: it is the timeout
- *          (in milliseconds) for waiting on action on this socket (and the
- *          given time period starts when the callback is called) until you
- *          should call curl_multi_socket() with the timeout stuff mentioned
- *          above. If "actions" happens on the socket before the timeout
- *          happens, remember that the timout timer keeps ticking until told
- *          otherwise.
- *
- *          The "what" argument has one of five values:
- *
- *            0 CURL_POLL_NONE (0)   - register, not interested in readiness
- *            1 CURL_POLL_IN         - register, interested in read readiness
- *            2 CURL_POLL_OUT        - register, interested in write readiness
- *            3 CURL_POLL_INOUT      - register, interested in both
- *            4 CURL_POLL_REMOVE     - deregister
+ *          detected to have "action" on them and let libcurl perform.
+ *          See man page for details.
