Marcel Raad (4 Apr 2019)
- VS projects: use Unicode for VC10+
  
  All Windows APIs have been natively UTF-16 since Windows 2000 and the
  non-Unicode variants are just wrappers around them. Only Windows 9x
  doesn't understand Unicode without the UnicoWS DLL. As later Visual
  Studio versions cannot target Windows 9x anyway, using the ANSI API
  doesn't really have any benefit there.
  
  This avoids issues like KNOWN_BUGS 6.5.

- travis: actually use updated compiler versions
  
  For the Linux builds, GCC 8 and 7 and clang 7 were installed, but the
  new GCC versions were only used for the coverage build and for building
  nghttp2, while the new clang version was not used at all.
  
  BoringSSL needs to use the default GCC as it respects CC, but not CXX,
  so it would otherwise pass gcc 8 options to g++ 4.8 and fail.
  
  Also remove GCC 7, it's not needed anymore.

  examples/externalsocket: add missing close socket calls
  
  .. and for Windows also call WSACleanup since we call WSAStartup.
  
  The example is to demonstrate handling the socket independently of
  libcurl. In this case libcurl is not responsible for creating, opening
  or closing the socket, it is handled by the application (our example).

Daniel Stenberg (11 Mar 2019)
- multi: removed unused code for request retries
  
  This code was once used for the non multi-interface using code path, but

- doh: inherit some SSL options from user's easy handle
  
  - Inherit SSL options for the doh handle but not SSL client certs,
    SSL ALPN/NPN, SSL engine, SSL version, SSL issuer cert,
    SSL pinned public key, SSL ciphers, SSL id cache setting,
    SSL kerberos or SSL gss-api settings.
  
  - Fix inheritance of verbose setting.
  
  - Inherit NOSIGNAL.
  
  There is no way for the user to set options for the doh (DNS-over-HTTPS)
  handles and instead we inherit some options from the user's easy handle.
  
  My thinking for the SSL options not inherited is they are most likely
  not intended by the user for the DOH transfer. I did inherit insecure
  because I think that should still be in control of the user.
  
  Prior to this change doh did not work for me because CAINFO was not
  inherited. Also verbose was set always which AFAICT was a bug (#3660).

- ssh: loop the state machine if not done and not blocking
  
  If the state machine isn't complete, didn't fail and it didn't return
  due to blocking it can just as well loop again.
  
  This addresses the problem with SFTP directory listings where we would
  otherwise return back to the parent and as the multi state machine
  doesn't have any code for using CURLM_CALL_MULTI_PERFORM for as long the
  doing phase isn't complete, it would return out when in reality there
  was more data to deal with.

- multi: support verbose conncache closure handle
  
  - Change closure handle to receive verbose setting from the easy handle
    most recently added via curl_multi_add_handle.
  
  The closure handle is a special easy handle used for closing cached
  connections. It receives limited settings from the easy handle most
  recently added to the multi handle. Prior to this change that did not
  include verbose which was a problem because on connection shutdown
  verbose mode was not acknowledged.

- 10-at-a-time.c: fix too long line

- [Arnaud Rebillout brought this change]

  examples: various fixes in ephiperfifo.c
  
  The main change here is the timer value that was wrong, it was given in
  usecs (ms * 1000), while the itimerspec struct wants nsecs (ms * 1000 *
  1000). This resulted in the callback being invoked WAY TOO OFTEN.
  
  As a quick check you can run this command before and after applying this
  commit:
  
      # shell 1
      ./ephiperfifo 2>&1 | tee ephiperfifo.log
      # shell 2

  If the cookieinfo pointer is NULL there really is nothing to save.
  
  Without this fix, we got a problem when a handle was using shared object
  with cookies and is told to "FLUSH" it to file (which worked) and then
  the share object was removed and when the easy handle was closed just
  afterwards it has no cookieinfo and no cookies so it decided to save an
  empty jar (overwriting the file just flushed).

  Instead of using a fixed 256 byte buffer in the connectdata struct.
  
  In my build, this reduces the size of the connectdata struct by 11.8%,
  from 2160 to 1904 bytes with no functionality or performance loss.
  
  This also fixes a bug in schannel's Curl_verify_certificate where it
  called Curl_sspi_strerror when it should have called Curl_strerror for
  string from GetLastError. the only effect would have been no text or the
  wrong text being shown for the error.

  - Split off connection shutdown procedure from Curl_disconnect into new

  - Change the shutdown procedure to close the sockets before

  Jan 2019 (#3442) to separate transfers from connections.

- easy: fix win32 init to work without CURL_GLOBAL_WIN32
  
  - Change the behavior of win32_init so that the required initialization
    procedures are not affected by CURL_GLOBAL_WIN32 flag.
  
  libcurl via curl_global_init supports initializing for win32 with an
  optional flag CURL_GLOBAL_WIN32, which if omitted was meant to stop
  Winsock initialization. It did so internally by skipping win32_init()
  when that flag was set. Since then win32_init() has been expanded to
  include required initialization routines that are separate from
  Winsock and therefore must be called in all cases. This commit fixes
  it so that CURL_GLOBAL_WIN32 only controls the optional win32
  initialization (which is Winsock initialization, according to our doc).
  
  The only users affected by this change are those that don't pass
  CURL_GLOBAL_WIN32 to curl_global_init. For them this commit removes the
  risk of a potential crash.

  connection_check: restore original conn->data after the check
  
  - Save the original conn->data before it's changed to the specified
    data transfer for the connection check and then restore it afterwards.
  
  This is a follow-up to 38d8e1b 2019-02-11.
  
  History:
  
  It was discovered a month ago that before checking whether to extract a
  dead connection that that connection should be associated with a "live"
  transfer for the check (ie original conn->data ignored and set to the
  passed in data). A fix was landed in 54b201b which did that and also
  cleared conn->data after the check. The original conn->data was not
  restored, so presumably it was thought that a valid conn->data was no
  longer needed.
  
  Several days later it was discovered that a valid conn->data was needed
  after the check and follow-up fix was landed in bbae24c which partially
  reverted the original fix and attempted to limit the scope of when
  conn->data was changed to only when pruning dead connections. In that
  case conn->data was not cleared and the original conn->data not
  restored.
  
  A month later it was discovered that the original fix was somewhat
  correct; a "live" transfer is needed for the check in all cases
  because original conn->data could be null which could cause a bad deref
  at arbitrary points in the check. A fix was landed in 38d8e1b which
  expanded the scope to all cases. conn->data was not cleared and the
  original conn->data not restored.
  
  A day later it was discovered that not restoring the original conn->data
  may lead to busy loops in applications that use the event interface, and
  given this observation it's a pretty safe assumption that there is some
  code path that still needs the original conn->data. This commit is the
  follow-up fix for that, it restores the original conn->data after the
  connection check.

  bearssl: Improve I/O handling
  
  Factor out common I/O loop as bearssl_run_until, which reads/writes TLS
  records until the desired engine state is reached. This is now used for
  the handshake, read, write, and close.
  
  Match OpenSSL SSL_write behavior, and don't return the number of bytes
  written until the corresponding records have been completely flushed
  across the socket. This involves keeping track of the length of data
  buffered into the TLS engine, and assumes that when CURLE_AGAIN is
  returned, the write function will be called again with the same data
  and length arguments. This is the same requirement of SSL_write.
  
  Handle TLS close notify as EOF when reading by returning 0.

- CURLOPT_HEADERFUNCTION.3: Document that size is always 1
  
  For compatibility with `fwrite`, the `CURLOPT_HEADERFUNCTION` callback
  is passed two `size_t` parameters which, when multiplied, designate the
  number of bytes of data passed in. In practice, CURL always sets the
  first parameter (`size`) to 1.
  
  This practice is also enshrined in documentation and cannot be changed
  in future. The documentation states that the default callback is
  `fwrite`, which means `fwrite` must be a suitable function for this
  purpose. However, the documentation also states that the callback must
  return the number of *bytes* it successfully handled, whereas ISO C
  `fwrite` returns the number of items (each of size `size`) which it
  wrote. The only way these numbers can be equal is if `size` is 1.
  
  Since `size` is 1 and can never be changed in future anyway, document
  that fact explicitly and let users rely on it.

- travis: make torture use --shallow=40
  
  As a first step to enable it to run over a more diverse set of tests in

- runtests: introduce --shallow to reduce huge torture tests
  
  When set, shallow mode limits runtests -t to make no more than NUM fails
  per test case. If more are found, it will randomly discard entries until
  the number is right. The random seed can also be set.
  
  This is particularly useful when running MANY tests as then most torture
  failures will already fail the same functions over and over and make the
  total operation painfully tedious.
  
  Closes #4699

- conncache: CONNECT_ONLY connections assumed always in-use
  
  This makes them never to be considered "the oldest" to be discarded when
  reaching the connection cache limit. The reasoning here is that
  CONNECT_ONLY is primarily used in combination with using the
  connection's socket post connect and since that is used outside of
  curl's knowledge we must assume that it is in use until explicitly
  closed.

- build: Disable Visual Studio warning "conditional expression is constant"
  
  - Disable warning C4127 "conditional expression is constant" globally
    in curl_setup.h for when building with Microsoft's compiler.
  
  This mainly affects building with the Visual Studio project files found
  in the projects dir.
  
  Prior to this change the cmake and winbuild build systems already
  disabled 4127 globally for when building with Microsoft's compiler.
  Also, 4127 was already disabled for all build systems in the limited
  circumstance of the WHILE_FALSE macro which disabled the warning
  specifically for while(0). This commit removes the WHILE_FALSE macro and
  all other cruft in favor of disabling globally in curl_setup.
  
  Background:
  
  We have various macros that cause 0 or 1 to be evaluated, which would
  cause warning C4127 in Visual Studio. For example this causes it:
  
      #define Curl_resolver_asynch() 1
  
  Full behavior is not clearly defined and inconsistent across versions.
  However it is documented that since VS 2015 Update 3 Microsoft has
  addressed this somewhat but not entirely, not warning on while(true) for
  example.
  
  Prior to this change some C4127 warnings occurred when I built with
  Visual Studio using the generated projects in the projects dir.

- strerror: Add Curl_winapi_strerror for Win API specific errors
  
  - In all code call Curl_winapi_strerror instead of Curl_strerror when
    the error code is known to be from Windows GetLastError.
  
  Curl_strerror prefers CRT error codes (errno) over Windows API error
  codes (GetLastError) when the two overlap. When we know the error code
  is from GetLastError it is more accurate to prefer the Windows API error
  messages.

  http_ntlm: Remove duplicate NSS initialisation
  
  Given that this is performed by the NTLM code there is no need to
  perform the initialisation in the HTTP layer. This also keeps the
  initialisation the same as the SASL based protocols and also fixes a
  possible compilation issue if both NSS and SSPI were to be used as

- checksrc: fix regexp for ASSIGNWITHINCONDITION
  
  The regexp looking for assignments within conditions was too greedy
  and matched a too long string in the case of multiple conditionals
  on the same line. This is basically only a problem in single line
  macros, and the code which exemplified this was essentially:
  
    do { if((x) != NULL) { x = NULL; } } while(0)
  
  ..where the final parenthesis of while(0) matched the regexp, and
  the legal assignment in the block triggered the warning. Fix by
  making the regexp less greedy by matching for the tell-tale signs
  of the if statement ending.
  
  Also remove the one occurrence where the warning was disabled due
  to a construction like the above, where the warning didn't apply
  when fixed.

Jay Satiro (22 Nov 2019)
- openssl: Revert to less sensitivity for SYSCALL errors
  
  - Disable the extra sensitivity except in debug builds (--enable-debug).
  
  - Improve SYSCALL error message logic in ossl_send and ossl_recv so that
    "No error" / "Success" socket error text isn't shown on SYSCALL error.
  
  Prior to this change 0ab38f5 (precedes 7.67.0) increased the sensitivity
  of OpenSSL's SSL_ERROR_SYSCALL error so that abrupt server closures were
  also considered errors. For example, a server that does not send a known
  protocol termination point (eg HTTP content length or chunked encoding)
  _and_ does not send a TLS termination point (close_notify alert) would
  cause an error if it closed the connection.
  
  To be clear that behavior made it into release build 7.67.0
  unintentionally. Several users have reported it as an issue.
  
  Ultimately the idea is a good one, since it can help prevent against a
  truncation attack. Other SSL backends may already behave similarly (such
  as Windows native OS SSL Schannel). However much more of our user base
  is using OpenSSL and there is a mass of legacy users in that space, so I
  think that behavior should be partially reverted and then rolled out
  slowly.
  
  This commit changes the behavior so that the increased sensitivity is
  disabled in all curl builds except curl debug builds (DEBUGBUILD). If
  after a period of time there are no major issues then it can be enabled
  in dev and release builds with the newest OpenSSL (1.1.1+), since users
  using the newest OpenSSL are the least likely to have legacy problems.

  The FormatMessage Windows API call which turns a Windows error code into

................................................................................

## Disabling Specific Protocols in Windows builds

The configure utility, unfortunately, is not available for the Windows
environment, therefore, you cannot use the various disable-protocol options of
the configure utility on this platform.

However, you can use the following defines to disable specific
protocols:

 - `HTTP_ONLY`             disables all protocols except HTTP
 - `CURL_DISABLE_FTP`      disables FTP
 - `CURL_DISABLE_LDAP`     disables LDAP
 - `CURL_DISABLE_TELNET`   disables TELNET
 - `CURL_DISABLE_DICT`     disables DICT
 - `CURL_DISABLE_FILE`     disables FILE
 - `CURL_DISABLE_TFTP`     disables TFTP
 - `CURL_DISABLE_HTTP`     disables HTTP
 - `CURL_DISABLE_IMAP`     disables IMAP
 - `CURL_DISABLE_POP3`     disables POP3
 - `CURL_DISABLE_SMTP`     disables SMTP

If you want to set any of these defines you have the following options:

 - Modify `lib/config-win32.h`
 - Modify `lib/curl_setup.h`
 - Modify `winbuild/Makefile.vc`
 - Modify the "Preprocessor Definitions" in the libcurl project

# Android

When building curl for Android it's recommended to use a Linux environment
since using curl's `configure` script is the easiest way to build curl
for Android. Before you can build curl for Android, you need to install the
Android NDK first. This can be done using the SDK Manager that is part of
Android Studio. Once you have installed the Android NDK, you need to figure out
where it has been installed and then set up some environment variables before
launching `configure`. On macOS, those variables could look like this to compile
for `aarch64` and API level 29:

    export NDK=~/Library/Android/sdk/ndk/20.1.5948944
    export HOST_TAG=darwin-x86_64
    export TOOLCHAIN=$NDK/toolchains/llvm/prebuilt/$HOST_TAG
    export AR=$TOOLCHAIN/bin/aarch64-linux-android-ar
    export AS=$TOOLCHAIN/bin/aarch64-linux-android-as
    export CC=$TOOLCHAIN/bin/aarch64-linux-android29-clang
    export CXX=$TOOLCHAIN/bin/aarch64-linux-android29-clang++
    export LD=$TOOLCHAIN/bin/aarch64-linux-android-ld
    export RANLIB=$TOOLCHAIN/bin/aarch64-linux-android-ranlib
    export STRIP=$TOOLCHAIN/bin/aarch64-linux-android-strip

When building on Linux or targeting other API levels or architectures, you need
to adjust those variables accordingly. After that you can build curl like this:

    ./configure --host aarch64-linux-android --with-pic --disable-shared

Note that this won't give you SSL/TLS support. If you need SSL/TLS, you have
to build curl against a SSL/TLS layer, e.g. OpenSSL, because it's impossible for
curl to access Android's native SSL/TLS layer. To build curl for Android using
OpenSSL, follow the OpenSSL build instructions and then install `libssl.a` and
`libcrypto.a` to `$TOOLCHAIN/sysroot/usr/lib` and copy `include/openssl` to
`$TOOLCHAIN/sysroot/usr/include`. Now you can build curl for Android using
OpenSSL like this:
    
    ./configure --host aarch64-linux-android --with-pic --disable-shared --with-ssl="$TOOLCHAIN/sysroot/usr"

Note, however, that you must target at least Android M (API level 23) or `configure`
won't be able to detect OpenSSL since `stderr` (and the like) weren't defined
before Android M.

 12. LDAP and OpenLDAP
 12.1 OpenLDAP hangs after returning results
 12.2 LDAP on Windows does authentication wrong?
 12.3 LDAP on Windows doesn't work

 13. TCP/IP
 13.1 --interface for ipv6 binds to unusable IP address

 14 DICT
 14.1 DICT responses show the underlying protocol

................................................................................

2.8 Schannel disable CURLOPT_SSL_VERIFYPEER and verify hostname

 This seems to be a limitation in the underlying Schannel API.

 https://github.com/curl/curl/issues/3284

2.9 TLS session cache doesn't work with TFO

 See https://github.com/curl/curl/issues/4301

3. Email protocols

3.1 IMAP SEARCH ALL truncated response

 IMAP "SEARCH ALL" truncates output on large boxes. "A quick search of the
 code reveals that pingpong.c contains some truncation code, at line 408, when
 it deems the server response to be too large truncating it to 40 characters"
................................................................................

 See https://github.com/curl/curl/issues/3229

5. Build and portability issues

5.1 USE_UNIX_SOCKETS on Windows

 Due to incorrect CMake checks for the presence of the feature, it will never
 be enabled for windows in a cmake build.

 See https://github.com/curl/curl/issues/4040

5.2 curl-config --libs contains private details

 "curl-config --libs" will include details set in LDFLAGS when configure is
................................................................................
 See https://github.com/curl/curl/issues/868

11.5 Connection information when using TCP Fast Open

 CURLINFO_LOCAL_PORT (and possibly a few other) fails when TCP Fast Open is
 enabled.

 See https://github.com/curl/curl/issues/1332 and
 https://github.com/curl/curl/issues/4296

11.6 slow connect to localhost on Windows

 When connecting to "localhost" on Windows, curl will resolve the name for
 both ipv4 and ipv6 and try to connect to both happy eyeballs-style. Something
 in there does however make it take 200 milliseconds to succeed - which is the
 HAPPY_EYEBALLS_TIMEOUT define exactly. Lowering that define speeds up the
................................................................................
 See https://github.com/curl/curl/issues/622 and
     https://curl.haxx.se/mail/lib-2016-01/0101.html

12.2 LDAP on Windows does authentication wrong?

 https://github.com/curl/curl/issues/3116

12.3 LDAP on Windows doesn't work

 A simple curl command line getting "ldap://ldap.forumsys.com" returns an
 error that says "no memory" !

 https://github.com/curl/curl/issues/4261

13. TCP/IP

13.1 --interface for ipv6 binds to unusable IP address

 Since IPv6 provides a lot of addresses with different scope, binding to an
 IPv6 address needs to take the proper care so that it doesn't bind to a
 locally scoped address as that is bound to fail.

The progress meter that is displayed when doing parallel transfers is
completely different than the regular one used for each single transfer.

  It shows:

 o percent download (if known, which means *all* transfers need to have a
   known size)
 o precent upload (if known, with the same caveat as for download)
 o total amount of downloaded data
 o total amount of uploaded data
 o number of transfers to perform
 o number of concurrent transfers being transferred right now
 o number of transfers queued up waiting to start
 o total time all transfers are expected to take (if sizes are known)
 o current time the transfers have spent so far

 All bugs documented in the KNOWN_BUGS document are subject for fixing!

 1. libcurl
 1.1 TFO support on Windows
 1.2 Consult %APPDATA% also for .netrc
 1.3 struct lifreq

 1.5 get rid of PATH_MAX
 1.7 Support HTTP/2 for HTTP(S) proxies
 1.8 CURLOPT_RESOLVE for any port number
 1.9 Cache negative name resolves
 1.10 auto-detect proxy
 1.11 minimize dependencies with dynamically loaded modules
 1.12 updated DNS server while running
................................................................................
 20.1 SSL tunnel
 20.2 nicer lacking perl message
 20.3 more protocols supported
 20.4 more platforms supported
 20.5 Add support for concurrent connections
 20.6 Use the RFC6265 test suite
 20.7 Support LD_PRELOAD on macOS


 21. Next SONAME bump
 21.1 http-style HEAD output for FTP
 21.2 combine error codes
 21.3 extend CURLOPT_SOCKOPTFUNCTION prototype

 22. Next major release
................................................................................

1.3 struct lifreq

 Use 'struct lifreq' and SIOCGLIFADDR instead of 'struct ifreq' and
 SIOCGIFADDR on newer Solaris versions as they claim the latter is obsolete.
 To support IPv6 interface addresses for network interfaces properly.








1.5 get rid of PATH_MAX

 Having code use and rely on PATH_MAX is not nice:
 https://insanecoding.blogspot.com/2007/11/pathmax-simply-isnt.html

 Currently the libssh2 SSH based code uses it, but to remove PATH_MAX from
 there we need libssh2 to properly tell us when we pass in a too small buffer
................................................................................
 To fix this, libcurl would have to detect an existing connection and "attach"
 the new transfer to the existing one.

17.2 Handle growing SFTP files

 The SFTP code in libcurl checks the file size *before* a transfer starts and
 then proceeds to transfer exactly that amount of data. If the remote file
 grows while the tranfer is in progress libcurl won't notice and will not
 adapt. The OpenSSH SFTP command line tool does and libcurl could also just
 attempt to download more to see if there is more to get...

 https://github.com/curl/curl/issues/4344

17.3 Support better than MD5 hostkey hash

................................................................................

20.7 Support LD_PRELOAD on macOS

 LD_RELOAD doesn't work on macOS, but there are tests which require it to run
 properly. Look into making the preload support in runtests.pl portable such
 that it uses DYLD_INSERT_LIBRARIES on macOS.










21. Next SONAME bump

21.1 http-style HEAD output for FTP

 #undef CURL_FTP_HTTPSTYLE_HEAD in lib/ftp.c to remove the HTTP-style headers
 from being output in NOBODY requests over FTP

 To support IPv6 interface addresses for network interfaces properly.

1.4 alt-svc sharing

 The share interface could benefit from allowing the alt-svc cache to be
 possible to share between easy handles.

 See https://github.com/curl/curl/issues/4476

20.8 Run web-platform-tests url tests

 Run web-platform-tests url tests and compare results with browsers on wpt.fyi

 It would help us find issues to fix and help us document where our parser
 differs from the WHATWG URL spec parsers.

 See https://github.com/curl/curl/issues/4477

Long: alt-svc
Arg: <file name>
Protocols: HTTPS
Help: Enable alt-svc with this cache file
Added: 7.64.1
---
WARNING: this option is experiemental. Do not use in production.

This option enables the alt-svc parser in curl. If the file name points to an
existing alt-svc cache file, that will be used. After a completed transfer,
the cache will be saved to the file name again if it has been modified.

Specify a "" file name (zero length) to avoid loading/saving and make curl
just handle the cache in memory.

If this option is used several times, curl will load contents from all the
files but the the last one will be used for saving.

Long: etag-compare
Arg: <file>
Help: Pass an ETag from a file as a custom header
Protocols: HTTP
Added: 7.68.0
---
This option makes a conditional HTTP request for the specific
ETag read from the given file by sending a custom If-None-Match
header using the extracted ETag.

For correct results, make sure that specified file contains only a single
line with a desired ETag. An empty file is parsed as an empty ETag.

Use the option --etag-save to first save the ETag from a response, and
then use this option to compare using the saved ETag in a subsequent request.

\fCOMPARISON\fP: There are 2 types of comparison or ETags, Weak and Strong.
This option expects, and uses a strong comparison.

Long: etag-save
Arg: <file>
Help: Parse ETag from a request and save it to a file
Protocols: HTTP
Added: 7.68.0
---
This option saves an HTTP ETag to the specified file. Etag is
usually part of headers returned by a request. When server sends an
ETag, it must be enveloped by a double quote. This option extracts the
ETag without the double quotes and saves it into the <file>.

A server can send a week ETag which is prefixed by "W/". This identifier
is not considered, and only relevant ETag between quotation marks is parsed.

It an ETag wasn't send by the server or it cannot be parsed, and empty
file is created.

Added: 7.66.0
Mutexed: http1.1 http1.0 http2 http2-prior-knowledge
Requires: HTTP/3
Help: Use HTTP v3
See-also: http1.1 http2
---

WARNING: this option is experiemental. Do not use in production.

Tells curl to use HTTP version 3 directly to the host and port number used in
the URL. A normal HTTP/3 transaction will be done to a host and then get
redirected via Alt-SVc, but this option allows a user to circumvent that when
you know that the target speaks HTTP/3 on the given host and port.

This option will make curl fail if a QUIC connection cannot be established, it
cannot fall back to a lower HTTP version on its own.

Long: parallel-immediate
Help: Do not wait for multiplexing (with --parallel)
Added: 7.68.0
See-also: parallel parallel-max
---
When doing parallel transfers, this option will instruct curl that it should
rather prefer opening up more connections in parallel at once rather than
waiting to see if new transfers can be added as multiplexed streams on another
connection.

................................................................................
.IP "--abstract-unix-socket <path>"
(HTTP) Connect through an abstract Unix domain socket, instead of using the network.
Note: netstat shows the path of an abstract socket prefixed with '@', however
the <path> argument should not have this leading character.

Added in 7.53.0.
.IP "--alt-svc <file name>"
(HTTPS) WARNING: this option is experiemental. Do not use in production.

This option enables the alt-svc parser in curl. If the file name points to an
existing alt-svc cache file, that will be used. After a completed transfer,
the cache will be saved to the file name again if it has been modified.

Specify a "" file name (zero length) to avoid loading/saving and make curl

................................................................................
used to seed the random engine for SSL connections.

See also \fI--random-file\fP.
.IP "--engine <name>"
(TLS) Select the OpenSSL crypto engine to use for cipher operations. Use \fI--engine\fP
list to print a list of build-time supported engines. Note that not all (or
none) of the engines may be available at run-time.




























.IP "--expect100-timeout <seconds>"
(HTTP) Maximum time in seconds that you allow curl to wait for a 100-continue
response when curl emits an Expects: 100-continue header in its request. By
default curl will wait one second. This option accepts decimal values! When
curl stops waiting, it will continue as if the response has been received.

(HTTP) 
WARNING: this option is experiemental. Do not use in production.

Tells curl to use HTTP version 3 directly to the host and port number used in
the URL. A normal HTTP/3 transaction will be done to a host and then get
redirected via Alt-SVc, but this option allows a user to circumvent that when
you know that the target speaks HTTP/3 on the given host and port.

This option will make curl fail if a QUIC connection cannot be established, it

.TH curl 1 "November 16, 2016" "Curl 7.68.0" "Curl Manual"

.SH NAME
curl \- transfer a URL
.SH SYNOPSIS
.B curl [options / URLs]
.SH DESCRIPTION
.B curl
................................................................................
.IP "--abstract-unix-socket <path>"
(HTTP) Connect through an abstract Unix domain socket, instead of using the network.
Note: netstat shows the path of an abstract socket prefixed with '@', however
the <path> argument should not have this leading character.

Added in 7.53.0.
.IP "--alt-svc <file name>"
(HTTPS) WARNING: this option is experimental. Do not use in production.

This option enables the alt-svc parser in curl. If the file name points to an
existing alt-svc cache file, that will be used. After a completed transfer,
the cache will be saved to the file name again if it has been modified.

Specify a "" file name (zero length) to avoid loading/saving and make curl
just handle the cache in memory.
................................................................................
used to seed the random engine for SSL connections.

See also \fI--random-file\fP.
.IP "--engine <name>"
(TLS) Select the OpenSSL crypto engine to use for cipher operations. Use \fI--engine\fP
list to print a list of build-time supported engines. Note that not all (or
none) of the engines may be available at run-time.
.IP "--etag-compare <file>"
(HTTP) This option makes a conditional HTTP request for the specific
ETag read from the given file by sending a custom If-None-Match
header using the extracted ETag.

For correct results, make sure that specified file contains only a single
line with a desired ETag. An empty file is parsed as an empty ETag.

Use the option \fI--etag-save\fP to first save the ETag from a response, and
then use this option to compare using the saved ETag in a subsequent request.

\fCOMPARISON\fP: There are 2 types of comparison or ETags, Weak and Strong.
This option expects, and uses a strong comparison.

Added in 7.68.0.
.IP "--etag-save <file>"
(HTTP) This option saves an HTTP ETag to the specified file. Etag is
usually part of headers returned by a request. When server sends an
ETag, it must be enveloped by a double quote. This option extracts the
ETag without the double quotes and saves it into the <file>.

A server can send a week ETag which is prefixed by "W/". This identifier
is not considered, and only relevant ETag between quotation marks is parsed.

It an ETag wasn't send by the server or it cannot be parsed, and empty
file is created.

Added in 7.68.0.
.IP "--expect100-timeout <seconds>"
(HTTP) Maximum time in seconds that you allow curl to wait for a 100-continue
response when curl emits an Expects: 100-continue header in its request. By
default curl will wait one second. This option accepts decimal values! When
curl stops waiting, it will continue as if the response has been received.

See also \fI--connect-timeout\fP. Added in 7.47.0.
................................................................................
\fI--http2-prior-knowledge\fP requires that the underlying libcurl was built to support HTTP/2. This option overrides \fI--http1.1\fP and \fI-0, --http1.0\fP and \fI--http2\fP. Added in 7.49.0.
.IP "--http2"

See also \fI-O, --remote-name\fP and \fI--remote-name-all\fP and \fI-J, --remote-header-name\fP.
.IP "--parallel-immediate"
When doing parallel transfers, this option will instruct curl that it should
rather prefer opening up more connections in parallel at once rather than
waiting to see if new transfers can be added as multiplexed streams on another
connection.

See also \fI-Z, --parallel\fP and \fI--parallel-max\fP. Added in 7.68.0.
.IP "--parallel-max"
When asked to do parallel transfers, using \fI-Z, --parallel\fP, this option controls

TELNET options. See \fICURLOPT_TELNETOPTIONS(3)\fP

\fICURLE_OK\fP (zero) means that the option was set properly, non-zero means an
error occurred as \fI<curl/curl.h>\fP defines. See the \fIlibcurl-errors(3)\fP
man page for the full list with descriptions.





If you try to set an option that libcurl doesn't know about, perhaps because
the library is too old to support it or the option was removed in a recent
version, this function will return \fICURLE_UNKNOWN_OPTION\fP. If support for
the option was disabled at compile-time, it will return
\fICURLE_NOT_BUILT_IN\fP.

................................................................................
The calling application may pass additional curl_waitfd structures which are
similar to \fIpoll(2)\fP's pollfd structure to be waited on in the same call.

On completion, if \fInumfds\fP is non-NULL, it will be populated with the
total number of file descriptors on which interesting events occurred. This
number can include both libcurl internal descriptors as well as descriptors
provided in \fIextra_fds\fP.






If no extra file descriptors are provided and libcurl has no file descriptor
to offer to wait for, this function will instead wait during \fItimeout_ms\fP
milliseconds (or shorter if an internal timer indicates so). This is the
detail that makes this function different than \fIcurl_multi_wait(3)\fP.


This function is encouraged to be used instead of select(3) when using the
multi interface to allow applications to easier circumvent the common problem
with 1024 maximum file descriptors.

.SH NAME
curl_multi_wakeup - wakes up a sleeping curl_multi_poll call
.SH SYNOPSIS
#include <curl/curl.h>

CURLMcode curl_multi_wakeup(CURLM *multi_handle);
.ad
.SH DESCRIPTION
This function can be called from any thread and it wakes up a
sleeping \fIcurl_multi_poll(3)\fP call that is currently (or will be)
waiting for activity or a timeout.

If the function is called when there is no \fIcurl_multi_poll(3)\fP call,
it will cause the next call to return immediately.

Calling this function only guarantees to wake up the current (or the next
if there is no current) \fIcurl_multi_poll(3)\fP call, which means it is
possible that multiple calls to this function will wake up the same waiting
operation.

This function has no effect on \fIcurl_multi_wait(3)\fP calls.
.SH RETURN VALUE
CURLMcode type, general libcurl multi interface error code.
