+# cURL C code style
+
+Source code that has a common style is easier to read than code that uses
+different styles in different places. It helps making the code feel like one
+single code base. Easy-to-read is a very important property of code and helps
+making it easier to review when new things are added and it helps debugging
+code when developers are trying to figure out why things go wrong. A unified
+style is more important than individual contributors having their own personal
+tastes satisfied.
+
+Our C code has a few style rules. Most of them are verified and upheld by the
+lib/checksrc.pl script. Invoked with `make checksrc` or even by default by the
+build system when built after `./configure --enable-debug` has been used.
+
+It is normally not a problem for anyone to follow the guidelines, as you just
+need to copy the style already used in the source code and there are no
+particularly unusual rules in our set of rules.
+
+We also work hard on writing code that are warning-free on all the major
+platforms and in general on as many platforms as possible. Code that obviously
+will cause warnings will not be accepted as-is.
+
+## Naming
+
+Try using a non-confusing naming scheme for your new functions and variable
+names. It doesn't necessarily have to mean that you should use the same as in
+other places of the code, just that the names should be logical,
+understandable and be named according to what they're used for. File-local
+functions should be made static. We like lower case names.
+
+See the INTERNALS document on how we name non-exported library-global symbols.
+
+## Indenting
+
+We use only spaces for indentation, never TABs. We use two spaces for each new
+open brace.
+
+    if(something_is_true) {
+      while(second_statement == fine) {
+        moo();
+      }
+    }
+
+## Comments
+
+Since we write C89 code, `//` comments are not allowed. They weren't
+introduced in the C standard until C99. We use only `/*` and `*/` comments:
+
+    /* this is a comment */
+
+## Long lines
+
+Source code in curl may never be wider than 80 columns and there are two
+reasons for maintaining this even in the modern era of very large and high
+resolution screens:
+
+1. Narrower columns are easier to read than very wide ones. There's a reason
+   newspapers have used columns for decades or centuries.
+
+2. Narrower columns allow developers to easier show multiple pieces of code
+   next to each other in different windows. I often have two or three source
+   code windows next to each other on the same screen - as well as multiple
+   terminal and debugging windows.
+
+## Braces
+
+In if/while/do/for expressions, we write the open brace on the same line as
+the keyword and we then set the closing brace on the same indentation level as
+the initial keyword. Like this:
+
+    if(age < 40) {
+      /* clearly a youngster */
+    }
+
+When we write functions however, the opening brace should be in the first
+column of the first line:
+
+    int main(int argc, char **argv)
+    {
+      return 1;
+    }
+
+## 'else' on the following line
+
+When adding an `else` clause to a conditional expression using braces, we add
+it on a new line after the closing brace. Like this:
+
+    if(age < 40) {
+      /* clearly a youngster */
+    }
+    else {
+      /* probably grumpy */
+    }
+
+## No space before parentheses
+
+When writing expressions using if/while/do/for, there shall be no space
+between the keyword and the open parenthesis. Like this:
+
+    while(1) {
+      /* loop forever */
+    }
+
+## Use boolean conditions
+
+Rather than test a conditional value such as a bool against TRUE or FALSE, a
+pointer against NULL or != NULL and an int against zero or not zero in
+if/while conditions we prefer:
+
+    result = do_something();
+    if(!result) {
+      /* something went wrong */
+      return result;
+    }
+
+## No assignments in conditions
+
+To increase readability and reduce complexity of conditionals, we avoid
+assigning variables within if/while conditions. We frown upon this style:
+
+    if((ptr = malloc(100)) == NULL)
+      return NULL;
+
+and instead we encourage the above version to be spelled out more clearly:
+
+    ptr = malloc(100);
+    if(!ptr)
+      return NULL;
+
+## New block on a new line
+
+We never write multiple statements on the same source line, even for very
+short if() conditions.
+
+    if(a)
+      return TRUE;
+    else if(b)
+      return FALSE;
+
+and NEVER:
+
+    if(a) return TRUE;
+    else if(b) return FALSE;
+
+## Space around operators
+
+Please use spaces on both sides of operators in C expressions.  Postfix `(),
+[], ->, ., ++, --` and Unary `+, - !, ~, &` operators excluded they should
+have no space.
+
+Examples:
+
+    bla = func();
+    who = name[0];
+    age += 1;
+    true = !false;
+    size += -2 + 3 * (a + b);
+    ptr->member = a++;
+    struct.field = b--;
+    ptr = &address;
+    contents = *pointer;
+    complement = ~bits;
+
+## Platform dependent code
+
+Use `#ifdef HAVE_FEATURE` to do conditional code. We avoid checking for
+particular operating systems or hardware in the #ifdef lines. The HAVE_FEATURE
+shall be generated by the configure script for unix-like systems and they are
+hard-coded in the config-[system].h files for the others.
+
+We also encourage use of macros/functions that possibly are empty or defined
+to constants when libcurl is built without that feature, to make the code

- names. It doesn't necessarily have to mean that you should use the same as in
- other places of the code, just that the names should be logical,
- understandable and be named according to what they're used for. File-local

- Use the same indenting levels and bracing method as all the other code

- follow the tradition! ;-) This mainly means: 2-level indents, using spaces

- or while().

- Also note that we use if() and while() with no space before the parenthesis.

-2.3 Commenting
-
- Comment your source code extensively using C comments (/* comment */), DO NOT
- use C++ comments (// this style). Commented code is quality code and enables

-  Author: Daniel Stenberg <daniel@haxx.se>
-  URL: http://curl.haxx.se/legal/distro-dilemma.html
-
-Condition
-
- This document is written to describe the situation as it is right now.
- libcurl 7.16.1 is currently the latest version available. Things may of
- course change in the future.
-
- This document reflects my view and understanding of these things. Please tell
- me where and how you think I'm wrong, and I'll try to correct my mistakes.
-
-Background
-
- The Free Software Foundation has deemed the Original BSD license[1] to be
- "incompatible"[2] with GPL[3]. I'd rather say it is the other way around, but
- the point is the same: if you distribute a binary version of a GPL program,
- it MUST NOT be linked with any Original BSD-licensed parts or libraries.
- Doing so will violate the GPL license. For a long time, very many GPL
- licensed programs have avoided this license mess by adding an exception[8] to
- their license. And many others have just closed their eyes for this problem.
-
- libcurl is MIT-style[4] licensed - how on earth did this dilemma fall onto
- our plates?
-
- libcurl is only a little library. libcurl can be built to use OpenSSL for its
- SSL/TLS capabilities. OpenSSL is basically Original BSD licensed[5].
-
- If libcurl built to use OpenSSL is used by a GPL-licensed application and you
- decide to distribute a binary version of it (Linux distros - for example -
- tend to), you have a clash. GPL vs Original BSD.
-
- This dilemma is not libcurl-specific nor is it specific to any particular
- Linux distro. (This article mentions and refers to Debian several times, but
- only because Debian seems to be the only Linux distro to have faced this
- issue yet since no other distro is shipping libcurl built with two SSL
- libraries.)
-
-Part of the Operating System
-
- This would not be a problem if the used lib would be considered part of the
- underlying operating system, as then the GPL license has an exception
- clause[6] that allows applications to use such libs without having to be
- allowed to distribute it or its sources. Possibly some distros will claim
- that OpenSSL is part of their operating system.
-
- Debian does however not take this stance and has officially(?) claimed that
- OpenSSL is not a required part of the Debian operating system
-
- Some people claim that this paragraph cannot be exploited this way by a Linux
- distro, but I am not a lawyer and that is a discussion left outside of this
- document.
-
-GnuTLS
-
- Since May 2005 libcurl can get built to use GnuTLS instead of OpenSSL. GnuTLS
- is an LGPL[7] licensed library that offers a matching set of features as
- OpenSSL does. Now, you can build and distribute an TLS/SSL capable libcurl
- without including any Original BSD licensed code.
-
- I believe Debian is the first (only?) distro that provides libcurl/GnuTLS
- packages.
-
-yassl
-
- libcurl can get also get built to use yassl for the TLS/SSL layer. yassl is a
- GPL[3] licensed library.
-
-
-GnuTLS vs OpenSSL vs yassl
-
- While these three libraries offer similar features, they are not equal.
- libcurl does not (yet) offer a standardized stable ABI if you decide to
- switch from using libcurl-openssl to libcurl-gnutls or vice-versa. The GnuTLS
- and yassl support is very recent in libcurl and it has not been tested nor
- used very extensively, while the OpenSSL equivalent code has been used and
- thus matured since 1999.
-
- GnuTLS
-   - LGPL licensed
-   - supports SRP
-   - lacks SSLv2 support
-   - lacks MD2 support (used by at least some CA certs)
-   - lacks the crypto functions libcurl uses for NTLM
-
- OpenSSL
-   - Original BSD licensed
-   - lacks SRP
-   - supports SSLv2
-   - older and more widely used
-   - provides crypto functions libcurl uses for NTLM
-   - libcurl can do non-blocking connects with it in 7.15.4 and later
-
- yassl
-   - GPL licensed
-   - much untested and unproven in the real work by (lib)curl users so we don't
-     know a lot about restrictions or benefits from using this
-
-The Better License, Original BSD, GPL or LGPL?
-
- It isn't obvious or without debate to any objective interested party that
- either of these licenses are the "better" or even the "preferred" one in a
- generic situation.
-
- Instead, I think we should accept the fact that the SSL/TLS libraries and
- their different licenses will fit different applications and their authors
- differently depending on the applications' licenses and their general usage
- pattern (considering how GPL and LGPL libraries for example can be burdensome
- for embedded systems usage).
-
- In Debian land, there seems to be a common opinion that LGPL is "maximally
- compatible" with apps while Original BSD is not. Like this:
-
-        http://lists.debian.org/debian-devel/2005/09/msg01417.html
-
-More SSL Libraries
-
- In libcurl, there's no stopping us here. There are more Open Source/Free
- SSL/TLS libraries out there and we would very much like to support them as
- well, to offer application authors an even wider scope of choice.
-
-Application Angle of this Problem
-
- libcurl is built to use one SSL/TLS library. It uses a single fixed name (by
- default) on the built/created lib file, and applications are built/linked to
- use that single lib. Replacing one libcurl instance with another one that
- uses the other SSL/TLS library might break one or more applications (due to
- ABI differences and/or different feature set). You want your application to
- use the libcurl it was built for.
-
-Project cURL Angle of this Problem
-
- We distribute libcurl and everyone may build libcurl with either library at
- their choice. This problem is not directly a problem of ours. It merely
- affects users - GPL application authors only - of our lib as it comes
- included and delivered on some distros.
-
- libcurl has different ABI when built with different SSL/TLS libraries due to
- these reasons:
-
- 1. No one has worked on fixing this. The mutex/lock callbacks should be set
-    with a generic libcurl function that should use the proper underlying
-    functions.
-
- 2. The CURLOPT_SSL_CTX_FUNCTION option is not possible to "emulate" on GnuTLS
-    but simply requires OpenSSL.
-
- 3. There might be some other subtle differences just because nobody has yet
-    tried to make a fixed ABI like this.
-
-Distro Angle of this Problem
-
- To my knowledge there is only one distro that ships libcurl built with either
- OpenSSL or GnuTLS.
-
- Debian Linux is now (since mid September 2005) providing two different
- libcurl packages, one for libcurl built with OpenSSL and one built with
- GnuTLS. They use different .so names and can this both be installed in a
- single system simultaneously. This has been said to be a transitional system
- not desired to keep in the long run.

+HTTP/2 with curl
+================
+
+[HTTP/2 Spec](https://www.rfc-editor.org/rfc/rfc7540.txt)
+[http2 explained](https://daniel.haxx.se/http2/)
+
+Build prerequisites
+-------------------
+  - nghttp2
+  - OpenSSL, NSS, GnutTLS or PolarSSL with a new enough version
+
+[nghttp2](https://nghttp2.org/)
+-------------------------------
+
+libcurl uses this 3rd party library for the low level protocol handling
+parts. The reason for this is that HTTP/2 is much more complex at that layer
+than HTTP/1.1 (which we implement on our own) and that nghttp2 is an already
+existing and well functional library.
+
+We require at least version 1.0.0.
+
+Over an http:// URL
+-------------------
+
+If `CURLOPT_HTTP_VERSION` is set to `CURL_HTTP_VERSION_2_0`, libcurl will
+include an upgrade header in the initial request to the host to allow
+upgrading to HTTP/2.
+
+Possibly we can later introduce an option that will cause libcurl to fail if
+not possible to upgrade. Possibly we introduce an option that makes libcurl
+use HTTP/2 at once over http://
+
+Over an https:// URL
+--------------------
+
+If `CURLOPT_HTTP_VERSION` is set to `CURL_HTTP_VERSION_2_0`, libcurl will use
+ALPN (or NPN) to negotiate which protocol to continue with. Possibly introduce
+an option that will cause libcurl to fail if not possible to use HTTP/2.
+
+`CURL_HTTP_VERSION_2TLS` was added in 7.47.0 as a way to ask libcurl to prefer
+HTTP/2 for HTTPS but stick to 1.1 by default for plain old HTTP connections.
+
+ALPN is the TLS extension that HTTP/2 is expected to use. The NPN extension is
+for a similar purpose, was made prior to ALPN and is used for SPDY so early
+HTTP/2 servers are implemented using NPN before ALPN support is widespread.
+
+`CURLOPT_SSL_ENABLE_ALPN` and `CURLOPT_SSL_ENABLE_NPN` are offered to allow
+applications to explicitly disable ALPN or NPN.
+
+SSL libs
+--------
+
+The challenge is the ALPN and NPN support and all our different SSL
+backends. You may need a fairly updated SSL library version for it to
+provide the necessary TLS features. Right now we support:
+
+  - OpenSSL:  ALPN and NPN
+  - NSS:      ALPN and NPN
+  - GnuTLS:   ALPN
+  - PolarSSL: ALPN
+
+Multiplexing
+------------
+
+Starting in 7.43.0, libcurl fully supports HTTP/2 multiplexing, which is the
+term for doing multiple independent transfers over the same physical TCP
+connection.
+
+To take advantage of multiplexing, you need to use the multi interface and set
+`CURLMOPT_PIPELINING` to `CURLPIPE_MULTIPLEX`. With that bit set, libcurl will
+attempt to re-use existing HTTP/2 connections and just add a new stream over
+that when doing subsequent parallel requests.
+
+While libcurl sets up a connection to a HTTP server there is a period during
+which it doesn't know if it can pipeline or do multiplexing and if you add new
+transfers in that period, libcurl will default to start new connections for
+those transfers. With the new option `CURLOPT_PIPEWAIT` (added in 7.43.0), you
+can ask that a transfer should rather wait and see in case there's a
+connection for the same host in progress that might end up being possible to
+multiplex on. It favours keeping the number of connections low to the cost of
+slightly longer time to first byte transferred.
+
+Applications
+------------
+
+We hide HTTP/2's binary nature and convert received HTTP/2 traffic to headers
+in HTTP 1.1 style. This allows applications to work unmodified.
+
+curl tool
+---------
+
+curl offers the `--http2` command line option to enable use of HTTP/2.
+
+Since 7.47.0, the curl tool enables HTTP/2 by default for HTTPS connections.
+
+HTTP Alternative Services
+-------------------------
+
+Alt-Svc is a suggested extension with a corresponding frame (ALTSVC) in HTTP/2
+that tells the client about an alternative "route" to the same content for the
+same origin server that you get the response from. A browser or long-living
+client can use that hint to create a new connection asynchronously.  For
+libcurl, we may introduce a way to bring such clues to the applicaton and/or
+let a subsequent request use the alternate route
+automatically. [Spec](https://tools.ietf.org/html/draft-ietf-httpbis-alt-svc-14)
+
+TODO
+----
+
+  - Implement "prior-knowledge" HTTP/2 connections over clear text so that
+    curl can connect with HTTP/2 at once without 1.1+Upgrade.

-Structs in libcurl
-
-This document should cover 7.32.0 pretty accurately, but will make sense even
-for older and later versions as things don't change drastically that often.
-
- 1. The main structs in libcurl
-  1.1 SessionHandle
-  1.2 connectdata
-  1.3 Curl_multi
-  1.4 Curl_handler
-  1.5 conncache
-  1.6 Curl_share
-  1.7 CookieInfo
-
-==============================================================================
-
-1. The main structs in libcurl
-
-  1.1 SessionHandle
-
-  The SessionHandle handle struct is the one returned to the outside in the
-  external API as a "CURL *". This is usually known as an easy handle in API
-  documentations and examples.
-
-  Information and state that is related to the actual connection is in the
-  'connectdata' struct. When a transfer is about to be made, libcurl will
-  either create a new connection or re-use an existing one. The particular
-  connectdata that is used by this handle is pointed out by
-  SessionHandle->easy_conn.
-
-  Data and information that regard this particular single transfer is put in
-  the SingleRequest sub-struct.
-
-  When the SessionHandle struct is added to a multi handle, as it must be in
-  order to do any transfer, the ->multi member will point to the Curl_multi
-  struct it belongs to. The ->prev and ->next members will then be used by the
-  multi code to keep a linked list of SessionHandle structs that are added to
-  that same multi handle. libcurl always uses multi so ->multi *will* point to
-  a Curl_multi when a transfer is in progress.
-
-  ->mstate is the multi state of this particular SessionHandle. When
-  multi_runsingle() is called, it will act on this handle according to which
-  state it is in. The mstate is also what tells which sockets to return for a
-  specific SessionHandle when curl_multi_fdset() is called etc.
-
-  The libcurl source code generally use the name 'data' for the variable that
-  points to the SessionHandle.
-
-
-  1.2 connectdata
-
-  A general idea in libcurl is to keep connections around in a connection
-  "cache" after they have been used in case they will be used again and then
-  re-use an existing one instead of creating a new as it creates a significant
-  performance boost.
-
-  Each 'connectdata' identifies a single physical connection to a server. If
-  the connection can't be kept alive, the connection will be closed after use
-  and then this struct can be removed from the cache and freed.
-
-  Thus, the same SessionHandle can be used multiple times and each time select
-  another connectdata struct to use for the connection. Keep this in mind, as
-  it is then important to consider if options or choices are based on the
-  connection or the SessionHandle.
-
-  Functions in libcurl will assume that connectdata->data points to the
-  SessionHandle that uses this connection.
-
-  As a special complexity, some protocols supported by libcurl require a
-  special disconnect procedure that is more than just shutting down the
-  socket. It can involve sending one or more commands to the server before
-  doing so. Since connections are kept in the connection cache after use, the
-  original SessionHandle may no longer be around when the time comes to shut
-  down a particular connection. For this purpose, libcurl holds a special
-  dummy 'closure_handle' SessionHandle in the Curl_multi struct to 
-
-  FTP uses two TCP connections for a typical transfer but it keeps both in
-  this single struct and thus can be considered a single connection for most
-  internal concerns.
-
-  The libcurl source code generally use the name 'conn' for the variable that
-  points to the connectdata.
-
-
-  1.3 Curl_multi
-
-  Internally, the easy interface is implemented as a wrapper around multi
-  interface functions. This makes everything multi interface.
-
-  Curl_multi is the multi handle struct exposed as "CURLM *" in external APIs.
-
-  This struct holds a list of SessionHandle structs that have been added to
-  this handle with curl_multi_add_handle(). The start of the list is ->easyp
-  and ->num_easy is a counter of added SessionHandles.
-
-  ->msglist is a linked list of messages to send back when
-  curl_multi_info_read() is called. Basically a node is added to that list
-  when an individual SessionHandle's transfer has completed.
-
-  ->hostcache points to the name cache. It is a hash table for looking up name
-  to IP. The nodes have a limited life time in there and this cache is meant
-  to reduce the time for when the same name is wanted within a short period of
-  time.
-
-  ->timetree points to a tree of SessionHandles, sorted by the remaining time
-  until it should be checked - normally some sort of timeout. Each
-  SessionHandle has one node in the tree.
-
-  ->sockhash is a hash table to allow fast lookups of socket descriptor to
-  which SessionHandle that uses that descriptor. This is necessary for the
-  multi_socket API.
-
-  ->conn_cache points to the connection cache. It keeps track of all
-  connections that are kept after use. The cache has a maximum size.
-
-  ->closure_handle is described in the 'connectdata' section.
-
-  The libcurl source code generally use the name 'multi' for the variable that
-  points to the Curl_multi struct.
-
-
-  1.4 Curl_handler
-
-  Each unique protocol that is supported by libcurl needs to provide at least
-  one Curl_handler struct. It defines what the protocol is called and what
-  functions the main code should call to deal with protocol specific issues.
-  In general, there's a source file named [protocol].c in which there's a
-  "struct Curl_handler Curl_handler_[protocol]" declared. In url.c there's
-  then the main array with all individual Curl_handler structs pointed to from
-  a single array which is scanned through when a URL is given to libcurl to
-  work with.
-
-  ->scheme is the URL scheme name, usually spelled out in uppercase. That's
-  "HTTP" or "FTP" etc. SSL versions of the protcol need its own Curl_handler
-  setup so HTTPS separate from HTTP.
-
-  ->setup_connection is called to allow the protocol code to allocate protocol
-  specific data that then gets associated with that SessionHandle for the rest
-  of this transfer. It gets freed again at the end of the transfer. It will be
-  called before the 'connectdata' for the transfer has been selected/created.
-  Most protocols will allocate its private 'struct [PROTOCOL]' here and assign
-  SessionHandle->req.protop to point to it.
-
-  ->connect_it allows a protocol to do some specific actions after the TCP
-  connect is done, that can still be considered part of the connection phase.
-
-  Some protocols will alter the connectdata->recv[] and connectdata->send[]
-  function pointers in this function.
-
-  ->connecting is similarly a function that keeps getting called as long as the
-  protocol considers itself still in the connecting phase.
-
-  ->do_it is the function called to issue the transfer request. What we call
-  the DO action internally. If the DO is not enough and things need to be kept
-  getting done for the entire DO sequence to complete, ->doing is then usually
-  also provided. Each protocol that needs to do multiple commands or similar
-  for do/doing need to implement their own state machines (see SCP, SFTP,
-  FTP). Some protocols (only FTP and only due to historical reasons) has a
-  separate piece of the DO state called DO_MORE.
-
-  ->doing keeps getting called while issuing the transfer request command(s)
-
-  ->done gets called when the transfer is complete and DONE. That's after the
-  main data has been transferred.
-
-  ->do_more gets called during the DO_MORE state. The FTP protocol uses this
-  state when setting up the second connection.
-
-  ->proto_getsock
-  ->doing_getsock
-  ->domore_getsock
-  ->perform_getsock
-  Functions that return socket information. Which socket(s) to wait for which
-  action(s) during the particular multi state.
-
-  ->disconnect is called immediately before the TCP connection is shutdown.
-
-  ->readwrite gets called during transfer to allow the protocol to do extra
-  reads/writes
-
-  ->defport is the default report TCP or UDP port this protocol uses
-
-  ->protocol is one or more bits in the CURLPROTO_* set. The SSL versions have
-  their "base" protocol set and then the SSL variation. Like "HTTP|HTTPS".
-
-  ->flags is a bitmask with additional information about the protocol that will
-  make it get treated differently by the generic engine:
-
-    PROTOPT_SSL - will make it connect and negotiate SSL
-
-    PROTOPT_DUAL - this protocol uses two connections
-
-    PROTOPT_CLOSEACTION - this protocol has actions to do before closing the
-    connection. This flag is no longer used by code, yet still set for a bunch
-    protocol handlers.
-  
-    PROTOPT_DIRLOCK - "direction lock". The SSH protocols set this bit to
-    limit which "direction" of socket actions that the main engine will
-    concern itself about.
-
-    PROTOPT_NONETWORK - a protocol that doesn't use network (read file:)
-
-    PROTOPT_NEEDSPWD - this protocol needs a password and will use a default
-    one unless one is provided
-
-    PROTOPT_NOURLQUERY - this protocol can't handle a query part on the URL
-    (?foo=bar)
-
-
-  1.5 conncache
-
-  Is a hash table with connections for later re-use. Each SessionHandle has
-  a pointer to its connection cache. Each multi handle sets up a connection
-  cache that all added SessionHandles share by default.
-
-
-  1.6 Curl_share
-  
-  The libcurl share API allocates a Curl_share struct, exposed to the external
-  API as "CURLSH *".
-
-  The idea is that the struct can have a set of own versions of caches and
-  pools and then by providing this struct in the CURLOPT_SHARE option, those
-  specific SessionHandles will use the caches/pools that this share handle
-  holds.
-
-  Then individual SessionHandle structs can be made to share specific things
-  that they otherwise wouldn't, such as cookies.
-
-  The Curl_share struct can currently hold cookies, DNS cache and the SSL
-  session cache.
-
-  
-  1.7 CookieInfo
-
-  This is the main cookie struct. It holds all known cookies and related
-  information. Each SessionHandle has its own private CookieInfo even when
-  they are added to a multi handle. They can be made to share cookies by using
-  the share API.

+------

+- test suite
+

  A name resolve that has failed is likely to fail when made again within a
  short period of time. Currently we only cache positive responses.
 
+1.10 Support IDNA2008
+
+ International Domain Names are supported in libcurl since years back, powered
+ by libidn. libidn implements IDNA2003 which has been superseded by IDNA2008.
+ libidn2 is an existing library offering support for IDNA2008.
+
+1.11 minimize dependencies with dynamicly loaded modules
+
+ We can create a system with loadable modules/plug-ins, where these modules
+ would be the ones that link to 3rd party libs. That would allow us to avoid
+ having to load ALL dependencies since only the necessary ones for this
+ app/invoke/used protocols would be necessary to load.  See
+ https://github.com/curl/curl/issues/349
+
+1.12 have form functions use CURL handle argument
+
+ curl_formadd() and curl_formget() both currently have no CURL handle
+ argument, but both can use a callback that is set in the easy handle, and
+ thus curl_formget() with callback cannot function without first having
+ curl_easy_perform() (or similar) called - which is hard to grasp and a design
+ mistake.
+
+ The curl_formadd() design can probably also be reconsidered to make it easier
+ to use and less error-prone. Probably easiest by splitting it into several
+ function calls.
+
+1.13 Add CURLOPT_MAIL_CLIENT option
+
+ Rather than use the URL to specify the mail client string to present in the
+ HELO and EHLO commands, libcurl should support a new CURLOPT specifically for
+ specifying this data as the URL is non-standard and to be honest a bit of a
+ hack ;-)
+
+ Please see the following thread for more information:
+ https://curl.haxx.se/mail/lib-2012-05/0178.html
+
+1.14 Typesafe curl_easy_setopt()
+
+ One of the most common problems in libcurl using applications is the lack of
+ type checks for curl_easy_setopt() which happens because it accepts varargs
+ and thus can take any type.
+
+ One possible solution to this is to introduce a few different versions of the
+ setopt version for the different kinds of data you can set.
+
+  curl_easy_set_num() - sets a long value
+
+  curl_easy_set_large() - sets a curl_off_t value
+
+  curl_easy_set_ptr() - sets a pointer
+
+  curl_easy_set_cb() - sets a callback PLUS its callback data
+
+1.15 TCP Fast Open
+
+ RFC 7413 defines how to include data already in the TCP SYN handshake to
+ reduce latency.
+
+1.16 Try to URL encode given URL
+
+ Given a URL that for example contains spaces, libcurl could have an option
+ that would try somewhat harder than it does now and convert spaces to %20 and
+ perhaps URL encoded byte values over 128 etc (basically do what the redirect
+ following code already does).

  especially needed when adding many simultaneous handles using the same host
  name when the DNS resolver can get flooded.
 
+2.3 Non-blocking curl_multi_remove_handle()
+
+ The multi interface has a few API calls that assume a blocking behavior, like
+ add_handle() and remove_handle() which limits what we can do internally. The
+ multi API need to be moved even more into a single function that "drives"
+ everything in a non-blocking manner and signals when something is done. A
+ remove or add would then only ask for the action to get started and then
+ multi_perform() etc still be called until the add/remove is completed.
+
+2.4 Split connect and authentication process
+

+ phase. As such any failures during authentication won't trigger the relevant
+ QUIT or LOGOFF for protocols such as IMAP, POP3 and SMTP.
