Version 7.88.0 (15 Feb 2023)

Daniel Stenberg (15 Feb 2023)

- RELEASE-NOTES: synced

  7.88.0 release

- THANKS: added contributors from 7.88.0

- openssl: rename 'errcode_t' to 'sslerr_t'

  Turns out "/usr/include/et/com_err.h" typedefs this type (without proper
  variable scoping).

  comerr is the "common error description library" that apparently might be use
  d
  by krb5 code, which then makes this header get used in a curl build.

  Fixed #10502
  Closes #10500

Dan Fandrich (13 Feb 2023)

- CONTRIBUTE: More formally specify the commit description

  This codifies what people have actually used in git commits over the
  past 6 years. I've left off some lesser-used headers that appear to
  duplicate others and tried to describe a consistent use for several
  others that were used more arbitrarily.

  This makes it easier for new committers to find out the kinds of things
  we want to acknowledge, makes it easier to perform statistical analysis
  on commits, and opens the possibility of performing lint checks on
  descriptions before submission.

- KNOW_BUGS: cleanups with some changed to TODOs

  - remove "Excessive HTTP/2 packets with TCP_NODELAY"

    This is not a bug. Rather room for improvement.

  I believe these have been fixed:

  - 17.4 Connection failures with parallel HTTP/2
  - 17.5 HTTP/2 connections through HTTPS proxy frequently stall

  - remove "FTPS needs session reuse"

  That is still true, but curl should also do session reuse now.

  - remove "ASCII FTP"

  It is documented behavior, and not single user has asked for extended
  functionality here the last decade or so.

  - remove "Passive transfer tries only one IP address"

  add as a TODO

  - remove "DoH leaks memory after followlocation"

  With a recipe on how to reproduce, this is pointless to keep around

  - remove "DoH does not inherit all transfer options"

- windows: always use curl's basename() implementation

  The `basename()` [1][2] implementation provided by mingw-w64 [3] makes
  assumptions about input encoding and may break with non-ASCII strings.

  `basename()` was auto-detected with CMake, autotools and since
  68fa9bf3f5d7b4fcbb57619f70cb4aabb79a51f6 (2022-10-13), also in
  `Makefile.mk` after syncing its behaviour with the mainline build
  methods. A similar patch for curl-for-win broke official Windows
  builds earlier, in release 7.83.1_4 (2022-06-15).

  This patch forces all Windows builds to use curl's internal
  `basename()` implementation to avoid such problems.

- openldap: fix missing sasl symbols at build in specific configs

  If curl is built with openldap support (USE_OPENLDAP=1) but does not
  have also some other protocol (IMAP/SMTP/POP3) enabled that brings
  in Curl_sasl_* functions, then the build will fail with undefined
  references to various symbols:

  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_decode_mech'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_parse_url_auth
  _option'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_cleanup'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_can_authentica
  te'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_continue'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_start'
  ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_init'

  This was tracked down to these functions bein used in openldap.c but
  defined in curl_sasl.c and then forward in two vauth/ files to have
  a guard against a set of #define configurations that was now extended
  to cover also this case.

  Example configuration targeted that could reproduce the problem:

  curl 7.87.1-DEV () libcurl/7.87.1-DEV .... OpenLDAP/2.6.3
  Protocols: file ftp ftps http https ldap ldaps

- curl_setup: Disable by default recv-before-send in Windows

  Prior to this change a workaround for Windows to recv before every send
  was enabled by default. The way it works is a recv is called before
  every send and saves the received data, in case send fails because in
  Windows apparently that can wipe out the socket's internal received
  data buffer.

  This feature has led to several bugs because the way libcurl operates
  it waits on a socket to read or to write, and may not at all times
  check for buffered receive data.

  Two recent significant bugs this workaround caused:
  - Broken Schannel TLS 1.3 connections (#9431)
  - HTTP/2 arbitrary hangs (#10253)

  The actual code remains though it is disabled by default. Though future
  changes to connection filter buffering could improve the situation IMO
  it's just not tenable to manage this workaround.

- connections: introduce http/3 happy eyeballs

  New cfilter HTTP-CONNECT for h3/h2/http1.1 eyeballing.
  - filter is installed when `--http3` in the tool is used (or
    the equivalent CURLOPT_ done in the library)
  - starts a QUIC/HTTP/3 connect right away. Should that not
    succeed after 100ms (subject to change), a parallel attempt
    is started for HTTP/2 and HTTP/1.1 via TCP
  - both attempts are subject to IPv6/IPv4 eyeballing, same
    as happens for other connections
  - tie timeout to the ip-version HAPPY_EYEBALLS_TIMEOUT
  - use a `soft` timeout at half the value. When the soft timeout
    expires, the HTTPS-CONNECT filter checks if the QUIC filter
    has received any data from the server. If not, it will start
    the HTTP/2 attempt.

  HTTP/3(ngtcp2) improvements.
  - setting call_data in all cfilter calls similar to http/2 and vtls filters
    for use in callback where no stream data is available.
  - returning CURLE_PARTIAL_FILE for prematurely terminated transfers
  - enabling pytest test_05 for h3
  - shifting functionality to "connect" UDP sockets from ngtcp2
    implementation into the udp socket cfilter. Because unconnected
    UDP sockets are weird. For example they error when adding to a
    pollset.

  HTTP/3(quiche) improvements.
  - fixed upload bug in quiche implementation, now passes 251 and pytest
  - error codes on stream RESET
  - improved debug logs
  - handling of DRAIN during connect
  - limiting pending event queue

  HTTP/2 cfilter improvements.
  - use LOG_CF macros for dynamic logging in debug build
  - fix CURLcode on RST streams to be CURLE_PARTIAL_FILE
  - enable pytest test_05 for h2
  - fix upload pytests and improve parallel transfer performance.

  GOAWAY handling for ngtcp2/quiche
  - during connect, when the remote server refuses to accept new connections
    and closes immediately (so the local conn goes into DRAIN phase), the
    connection is torn down and a another attempt is made after a short grace
    period.
    This is the behaviour observed with nghttpx when we tell it to  shut
    down gracefully. Tested in pytest test_03_02.

  TLS improvements
  - ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, repl
  aces
    copy of logic in all tls backends.
  - standardized the infof logging of offered ALPNs
  - ALPN negotiated: have common function for all backends that sets alpn propr
  ty
    and connection related things based on the negotiated protocol (or lack the
  reof).

  - new tests/tests-httpd/scorecard.py for testing h3/h2 protocol implementatio
  n.
    Invoke:
      python3 tests/tests-httpd/scorecard.py --help
    for usage.

  Improvements on gathering connect statistics and socket access.
  - new CF_CTRL_CONN_REPORT_STATS cfilter control for having cfilters
    report connection statistics. This is triggered when the connection
    has completely connected.
  - new void Curl_pgrsTimeWas(..) method to report a timer update with
    a timestamp of when it happend. This allows for updating timers
    "later", e.g. a connect statistic after full connectivity has been
    reached.
  - in case of HTTP eyeballing, the previous changes will update
    statistics only from the filter chain that "won" the eyeballing.
  - new cfilter query CF_QUERY_SOCKET for retrieving the socket used
    by a filter chain.
    Added methods Curl_conn_cf_get_socket() and Curl_conn_get_socket()
    for convenient use of this query.
  - Change VTLS backend to query their sub-filters for the socket when
    checks during the handshake are made.

  HTTP/3 documentation on how https eyeballing works.

  TLS improvements
  - ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, repl
  aces
    copy of logic in all tls backends.
  - standardized the infof logging of offered ALPNs
  - ALPN negotiated: have common function for all backends that sets alpn propr
  ty
    and connection related things based on the negotiated protocol (or lack the
  reof).

  Scorecard with Caddy.
  - configure can be run with `--with-test-caddy=path` to specify which caddy t
  o use for testing
  - tests/tests-httpd/scorecard.py now measures download speeds with caddy

  pytest improvements
  - adding Makfile to clean gen dir
  - adding nghttpx rundir creation on start
  - checking httpd version 2.4.55 for test_05 cases where it is needed. Skippin
  g with message if too old.
  - catch exception when checking for caddy existance on system.

- urlapi: avoid Curl_dyn_addf() for hex outputs

  Inspired by the recent fixes to escape.c, we should avoid calling
  Curl_dyn_addf() in loops, perhaps in particular when adding something so
  simple as %HH codes - for performance reasons. This change makes the
  same thing for the URL parser's two URL-encoding loops.

  Closes #10384

- urlapi: skip path checks if path is just "/"

  As a miniscule optimization, treat a path of the length 1 as the same as
  non-existing, as it can only be a single leading slash, and that's what
  we do for no paths as well.

  Closes #10312

- cf-socket: improvements in socket I/O handling

  - Curl_write_plain/Curl_read_plain have been eliminated. Last code use
    now uses Curl_conn_send/recv so that requests use conn->send/revc
    callbacks which defaults to cfilters use.
  - Curl_recv_plain/Curl_send_plain have been internalized in cf-socket.c.
  - USE_RECV_BEFORE_SEND_WORKAROUND (active on Windows) has been moved
    into cf-socket.c. The pre_recv buffer is held at the socket filter
    context.  `postponed_data` structures have been removed from
    `connectdata`.
  - the hanger in HTTP/2 request handling was a result of read buffering
    on all sends and the multi handling is not prepared for this. The
    following happens:

     - multi preforms on a HTTP/2 easy handle
     - h2 reads and processes data
     - this leads to a send of h2 data
     - which receives and buffers before the send
     - h2 returns
     - multi selects on the socket, but no data arrives (its in the buffer alre
  ady)
     the workaround now receives data in a loop as long as there is something i
  n
     the buffer. The real fix would be for multi to change, so that `data_pendi
  ng`
     is evaluated before deciding to wait on the socket.

  io_buffer, optional, in cf-socket.c, http/2 sets state.drain if lower
  filter have pending data.

  This io_buffer is only available/used when the
  -DUSE_RECV_BEFORE_SEND_WORKAROUND is active, e.g. on Windows
  configurations. It also maintains the original checks on protocol
  handler being HTTP and conn->send/recv not being replaced.

  The HTTP/2 (nghttp2) cfilter now sets data->state.drain when it finds
  out that the "lower" filter chain has still pending data at the end of
  its IO operation. This prevents the processing from becoming stalled.

- write-out.d: clarify Windows % symbol escaping

  - Clarify that in Windows batch files the % must be escaped as %%, and
    at the command prompt it cannot be escaped which could lead to
    incorrect expansion.

  Prior to this change the doc implied % must be escaped as %% in win32
  always.

  ---

  Examples showing how a write-out argument is received by curl:

  If curl --write-out "%{http_code}" is executed in a batch file:
  {http_code}

  If curl --write-out "%%{http_code}" is executed in a batch file:
  %{http_code}

  If curl --write-out "%{http_code}" is executed from the command prompt:
  %{http_code}

  If curl --write-out "%%{http_code}" is executed from the command prompt:
  %%{http_code}

  At the command prompt something like "%{speed_download}%{http_code}"
  would first be parsed by the command interpreter as %{speed_download}%
  and would be expanded as environment variable {speed_download} if it
  existed, though that's highly unlikely since Windows environment names
  don't use braces.

- runtests: fix detection of TLS backends

  Built-in TLS backends are detected at test time by scanning for their

  the curl backend may be wrongly determined.

  In example, if the version line contains "libssh/0.10.4/openssl/zlib",
  OpenSSL is detected as a curl-configured backend even if not.

- http2: fix compiler warning due to uninitialized variable

  Prior to this change http2_cfilter_add could return an uninitialized

- docs/DEPRECATE.md: deprecate gskit

  Ref: #10163

  - This is a niche TLS library, only running on some IBM systems
  - no regular curl contributors use this backend
  - no CI builds use or verify this backend
  - gskit, or the curl adaption for it, lacks many modern TLS features
    making it an inferior solution

  The only TLS auth type libcurl ever supported is SRP and that is the

  If TLS auth is used, SRP is now implied.

- lib: connect/h2/h3 refactor

  Refactoring of connection setup and happy eyeballing. Move
  nghttp2. ngtcp2, quiche and msh3 into connection filters.

   - eyeballing cfilter that uses sub-filters for performing parallel connects
   - socket cfilter for all transport types, including QUIC
   - QUIC implementations in cfilter, can now participate in eyeballing
   - connection setup is more dynamic in order to adapt to what filter did
     really connect.  Relevant to see if a SSL filter needs to be added or
     if SSL has already been provided
   - HTTP/3 test cases similar to HTTP/2
   - multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche

   - Fix for data attach/detach in VTLS filters that could lead to crashes
     during parallel transfers.
   - Eliminating setup() methods in cfilters, no longer needed.
   - Improving Curl_conn_is_alive() to replace Curl_connalive() and
     integrated ssl alive checks into cfilter.
   - Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
     connection into and persist it at the easy handle.

   - Several more cfilter related cleanups and moves:
     - stream_weigth and dependency info is now wrapped in struct
       Curl_data_priority
     - Curl_data_priority members depend is available in HTTP2|HTTP3
     - Curl_data_priority members depend on NGHTTP2 support
     - handling init/reset/cleanup of priority part of url.c
     - data->state.priority same struct, but shallow copy for compares only

   - PROTOPT_STREAM has been removed
     - Curl_conn_is_mulitplex() now available to check on capability

   - Adding query method to connection filters.
     - ngtcp2+quiche: implementing query for max concurrent transfers.

   - Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
     - setting keepalive timestamp on connect
     - DATA_SETUP is called after the connection has been completely
       setup (but may not connected yet) to allow filters to initialize
       data members they use.

   - there is no socket to be had with msh3, it is unclear how select
     shall work

   - manual test via "curl --http3 https://curl.se" fail with "empty
     reply from server".

   - Various socket/conn related cleanups:
     - Curl_socket is now Curl_socket_open and in cf-socket.c
     - Curl_closesocket is now Curl_socket_close and in cf-socket.c
     - Curl_ssl_use has been replaced with Cur_conn_is_ssl
     - Curl_conn_tcp_accepted_set has been split into
       Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
       with a clearer purpose

- tests: avoid use of sha1 in certificates

  The SHA-1 algorithm is deprecated (particularly for security-sensitive
  applications) in a variety of OS environments. This already affects
  RHEL-9 and derivatives, which are not willing to use certificates using
  that algorithm. The fix is to use sha256 instead, which is already used
  for most of the other certificates in the test suite.

  Fixes #10135

  This gets rid of issues related to sha1 signatures.

  Manual steps after "make clean-certs" and "make build-certs":

  - Copy tests/certs/stunnel-sv.pem to tests/stunnel.pem
    (make clean-certs does not remove the original tests/stunnel.pem)

- http: remove the trace message "Mark bundle... multiuse"

  The message "Mark bundle as not supporting multiuse" was added at commit
  29364d93 when an http/2-related bug was fixed, and it appears to be a
  leftover trace message.

  This message should be removed because:
   * it conveys no information to the user
   * it is enabled in the default build (--enable-verbose)
   * it reads like a warning/unexpected condition
   * it is equivalent to "Detected http proto < 2", which is
     not a useful message.
   * it is a time-wasting red-herring for anyone who encounters
     it for the first time while investigating some other, real
