Version 7.66.0 (10 Sep 2019)

Daniel Stenberg (10 Sep 2019)
- RELEASE-NOTES: curl 7.66.0

- THANKS: from the 7.66.0 release

  
  The problem can be reproduced as follows:
  
   % curl --reso<TAB>
   % curl -E <TAB>
  
  Bug: https://bugs.debian.org/921452

- zsh.pl: update regex to better match curl -h output
  
  The current regex fails to match '<...>' arguments properly (e.g. those
  with spaces in them), which causes an completion script with wrong
  descriptions for some options.
  
  Here's a diff of the generated completion script, comparing the previous
  version to the one with this fix:

  runtests.pl: Fix perl call to include srcdir
  
  - Use explicit include opt for perl calls.
  
  Prior to this change some scripts couldn't find their dependencies.
  
  At the top, perl is called using with the "-Isrcdir" option, and it
  works:
  
  https://github.com/curl/curl/blob/curl-7_63_0/tests/runtests.pl#L183
  
  But on line 3868, that option is omitted. This caused problems for me,
  as the symbol-scan.pl script in particular couldn't find its
  dependencies properly:
  
  https://github.com/curl/curl/blob/curl-7_63_0/tests/runtests.pl#L3868

  libssh: do not let libssh create socket
  
  By default, libssh creates a new socket, instead of using the socket
  created by curl for SSH connections.
  
  Pass the socket created by curl to libssh using ssh_options_set() with
  SSH_OPTIONS_FD directly after ssh_new(). So libssh uses our socket
  instead of creating a new one.
  
  This approach is very similar to what is done in the libssh2 code, where
  the socket created by curl is passed to libssh2 when
  libssh2_session_startup() is called.

   Problem 1
  
  After LOTS of scratching my head, I eventually realized that even when doing
  10 uploads in parallel, sometimes the socket callback to the application that
  tells it what to wait for on the socket, looked like it would reflect the
  status of just the single transfer that just changed state.
  
  Digging into the code revealed that this was indeed the truth. When multiple
  transfers are using the same connection, the application did not correctly get
  the *combined* flags for all transfers which then could make it switch to READ
  (only) when in fact most transfers wanted to get told when the socket was
  WRITEABLE.
  
   Problem 1b
  
  A separate but related regression had also been introduced by me when I
  cleared connection/transfer association better a while ago, as now the logic
  couldn't find the connection and see if that was marked as used by more
  transfers and then it would also prematurely remove the socket from the socket
  hash table even in times other transfers were still using it!
  
   Fix 1
  
  Make sure that each socket stored in the socket hash has a "combined" action
  field of what to ask the application to wait for, that is potentially the ORed
  action of multiple parallel transfers. And remove that socket hash entry only
  if there are no transfers left using it.
  
   Problem 2
  
  The socket hash entry stored an association to a single transfer using that
  socket - and when curl_multi_socket_action() was called to tell libcurl about
  activities on that specific socket only that transfer was "handled".
  
  This was WRONG, as a single socket/connection can be used by numerous parallel
  transfers and not necessarily a single one.
  
   Fix 2
  
  We now store a list of handles in the socket hashtable entry and when libcurl
  is told there's traffic for a particular socket, it now iterates over all
  known transfers using that single socket.

  This is a companion patch to cbea2fd2c (NTLM: force the connection to
  HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1
  preemptively. However, with other (Negotiate) authentication it is not

- travis: enable COPYRIGHTYEAR extended warning
  
  The extended warning for checking incorrect COPYRIGHTYEAR is quite
  expensive to run, so rather than expecting every developer to do it
  we ensure it's turned on locally for Travis.

- checksrc: add COPYRIGHTYEAR check
  
  Forgetting to bump the year in the copyright clause when hacking has
  been quite common among curl developers, but a traditional checksrc
  check isn't a good fit as it would penalize anyone hacking on January
  1st (among other things). This adds a more selective COPYRIGHTYEAR
  check which intends to only cover the currently hacked on changeset.
  
  The check for updated copyright year is currently not enforced on all
  files but only on files edited and/or committed locally. This is due to
  the amount of files which aren't updated with their correct copyright
  year at the time of their respective commit.
  
  To further avoid running this expensive check for every developer, it
  adds a new local override mode for checksrc where a .checksrc file can
  be used to turn on extended warnings locally.

- openssl: support session resume with TLS 1.3
  
  Session resumption information is not available immediately after a TLS 1.3
  handshake. The client must wait until the server has sent a session ticket.
  
  Use OpenSSL's "new session" callback to get the session information and put it
  into curl's session cache. For TLS 1.3 sessions, this callback will be invoked
  after the server has sent a session ticket.
  
  The "new session" callback is invoked only if OpenSSL's session cache is
  enabled, so enable it and use the "external storage" mode which lets curl manage
  the contents of the session cache.
  
  A pointer to the connection data and the sockindex are now saved as "SSL extra
  data" to make them available to the callback.
  
  This approach also works for old SSL/TLS versions and old OpenSSL versions.

  ares: remove fd from multi fd set when ares is about to close the fd
  
  When using c-ares for asyn dns, the dns socket fd was silently closed
  by c-ares without curl being aware. curl would then 'realize' the fd
  has been removed at next call of Curl_resolver_getsock, and only then
  notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with
  CURL_POLL_REMOVE. At this point the fd is already closed.
  
  By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this
  patch allows curl to be notified that the fd is not longer needed
  for neither for write nor read. At this point by calling
  Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE
  before the fd is actually closed by ares.

# ngtcp2 version

## Build

Build (patched) OpenSSL

     % git clone --depth 1 -b openssl-quic-draft-22 https://github.com/tatsuhiro-t/openssl
     % cd openssl
     % ./config enable-tls1_3 --prefix=<somewhere1>
     % make
     % make install_sw

Build nghttp3

     % cd ..
     % git clone https://github.com/ngtcp2/nghttp3
     % cd nghttp3
     % autoreconf -i
     % ./configure --prefix=<somewhere2> --enable-lib-only
     % make
     % make install

Build ngtcp2

     % cd ..
     % git clone -b draft-22 https://github.com/ngtcp2/ngtcp2
     % cd ngtcp2
     % autoreconf -i
     % ./configure PKG_CONFIG_PATH=<somewhere1>/lib/pkgconfig:<somewhere2>/lib/pkgconfig LDFLAGS="-Wl,-rpath,<somehere1>/lib" --prefix==<somewhere3>
     % make
     % make install

Build curl

     % cd ..
     % git clone https://github.com/curl/curl
     % cd curl
     % ./buildconf
     % LDFLAGS="-Wl,-rpath,<somewhere1>/lib" ./configure -with-ssl=<somewhere1> --with-nghttp3=<somewhere2> --with-ngtcp2=<somewhere3>
     % make

## Running

Make sure the custom OpenSSL library is the one used at run-time, as otherwise
you'll just get ld.so linker errors.

## Invoke from command line

    curl --http3 https://nghttp2.org:8443/

# quiche version

## build

Clone quiche and BoringSSL:

     % git clone --recursive https://github.com/cloudflare/quiche

Build BoringSSL (it needs to be built manually so it can be reused with curl):

     % cd quiche/deps/boringssl
     % mkdir build
     % cd build
     % cmake -DCMAKE_POSITION_INDEPENDENT_CODE=on ..
     % make -j`nproc`
     % cd ..
     % mkdir .openssl/lib -p
     % cp build/crypto/libcrypto.a build/ssl/libssl.a .openssl/lib
     % ln -s $PWD/include .openssl

Build quiche:

     % cd ../..
     % QUICHE_BSSL_PATH=$PWD/deps/boringssl cargo build --release --features pkg-config-meta

Clone and build curl:

     % cd ..
     % git clone https://github.com/curl/curl
     % cd curl
     % ./buildconf
     % ./configure LDFLAGS="-Wl,-rpath,$PWD/../quiche/target/release" --with-ssl=$PWD/../quiche/deps/boringssl/.openssl --with-quiche=$PWD/../quiche/target/release
     % make -j`nproc`

## Running

Make an HTTP/3 request.

     % src/curl --http3 https://cloudflare-quic.com/
     % src/curl --http3 https://facebook.com/


     % src/curl --http3 https://quic.aiortc.org:4433/
     % src/curl --http3 https://quic.rocks:4433/

# how to install curl and libcurl

## Installing Binary Packages

Lots of people download binary distributions of curl and libcurl. This
document does not describe how to install curl or libcurl using such a binary
package. This document describes how to compile, build and install curl and
libcurl from source code.













## Building from git

If you get your code off a git repository instead of a release tarball, see
the `GIT-INFO` file in the root directory for specific instructions on how to
proceed.

# Unix

If you have OpenSSL installed somewhere else (for example, `/opt/OpenSSL`) and
you have pkg-config installed, set the pkg-config path first, like this:

    env PKG_CONFIG_PATH=/opt/OpenSSL/lib/pkgconfig ./configure --with-ssl

Without pkg-config installed, use this:

   ./configure --with-ssl=/opt/OpenSSL

If you insist on forcing a build without SSL support, even though you may
have OpenSSL installed in your system, you can run configure like this:

   ./configure --without-ssl

If you have OpenSSL installed, but with the libraries in one place and the
header files somewhere else, you have to set the `LDFLAGS` and `CPPFLAGS`
environment variables prior to running configure.  Something like this should
work:

    CPPFLAGS="-I/path/to/ssl/include" LDFLAGS="-L/path/to/ssl/lib" ./configure

These are problems and bugs known to exist at the time of this release. Feel
free to join in and help us correct one or more of these! Also be sure to
check the changelog of the current development status, as one or more of these
problems may have been fixed or changed somewhat since this was written!

1. HTTP

1.1 CURLFORM_CONTENTLEN in an array

 It is not possible to pass a 64-bit value using CURLFORM_CONTENTLEN with
 CURLFORM_ARRAY, when compiled on 32-bit platforms that support 64-bit
 integers. This is because the underlying structure 'curl_forms' uses a dual
 purpose char* for storing these values in via casting. For more information
 see the now closed related issue:
 https://github.com/curl/curl/issues/608

1.3 STARTTRANSFER time is wrong for HTTP POSTs

 Wrong STARTTRANSFER timer accounting for POST requests Timer works fine with
 GET requests, but while using POST the time for CURLINFO_STARTTRANSFER_TIME
 is wrong. While using POST CURLINFO_STARTTRANSFER_TIME minus
 CURLINFO_PRETRANSFER_TIME is near to zero every time.
