  when adding easy handles "on the fly". Bug report and test app provided by

since it then inits libgcrypt and libgcrypt is being evil and EXITS the

thing to do by a library.

been removed from a multi handle, and then fixed another flaw that prevented
curl_easy_duphandle() to work even after the first fix - the handle was
still marked as using the multi interface.

was 16385 bytes (16K+1) and it turned out we didn't properly always "suck
out" all data from libssh2. The effect being that libcurl would hang on the
socket waiting for data when libssh2 had in fact already read it all...

the CURLOPT_RESUME_FROM or CURLOPT_RANGE options and an existing connection
in the connection cache is closed to make room for the new one when you call
curl_easy_perform(). It would then wrongly free range-related data in the
connection close funtion.

can/will be used as it then makes the common cases save 16KB of data for each
easy handle that isn't used for pipelining.

  Curl_socket_ready(), Curl_poll() and Curl_select() when these are called
  with a zero timeout or a timeout value indicating a blocking call should
  be performed.

  These unnecessary calls to gettimeofday() got introduced in 7.16.2 when
  fixing 'timeout would restart when signal caught while awaiting socket
  events' on 20 March 2007.

  function that deprecates the curl_multi_socket() function. Using the new
  function the application tell libcurl what action that was found in the
  socket that it passes in. This gives a significant performance boost as it
  allows libcurl to avoid a call to poll()/select() for every call to
  curl_multi_socket*().

of a new host on the net with the same silly domain the test was using

embedded in the URL.

uses poll() when a fine poll() is available, so now libcurl can be
built without select() support at all if a fine poll() is available.

plus made --pass work on an SSH private key as well.

or Curl_poll() with a non-zero timeout both functions would restart the
specified timeout. This could even lead to the extreme case that if a
signal arrived with a frecuency lower to the specified timeout neither
function would ever exit.

Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
defined both functions will return as soon as a signal is caught. Use it
at your own risk, all calls to these functions in the library should be
revisited and checked before fully supporting this feature.

more frequently allowing same calling frecuency for the client progress
callback, while keeping the once a second frecuency for speed calculations
and internal display of the transfer progress.

  1) the progress callback gets called more frequently (at times)
  2) libcurl *might* call the callback when it receives a signal

  makefiles that are included in the source release archives, generated from
  the Makefile.vc6 files by the maketgz script. I also modified the root
  Makefile to have a VC variable that defaults to vc6 but can be overridden to
  allow it to be used for vc8 as well. Like this:

    nmake VC=vc8 vc

  server through a proxy and have the remote https server port set using the
  CURLOPT_PORT option, protocol gets reset to http from https after the first
  request.

  User defined URL was modified internally by libcurl and subsequent reuse of
  the easy handle may lead to connection using a different protocol (if not
  originally http).

  I found that libcurl hardcoded the protocol to "http" when it tries to
  regenerate the URL if CURLOPT_PORT is set. I tried to fix the problem as
  follows and it's working fine so far
