  One of the primary reasons we introduced c-ares support was to allow the name

- The ultimate goal is to provide the easy interface simply by wrapping the

+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.

+CURL SECURITY FOR DEVELOPERS
+
+This document is intended to provide guidance to curl developers on how
+security vulnerabilities should be handled.
+
+PUBLISHING INFORMATION
+
+All known and public curl or libcurl related vulnerabilities are listed at
+http://curl.haxx.se/docs/security.html
+
+Security vulnerabilities should not be entered in the project's public bug
+tracker unless the necessary configuration is in place to limit access to the
+issue to only the reporter and the project's security team.
+
+VULNERABILITY HANDLING
+
+The typical process for handling a new security vulnerability is as follows.
+
+No information should be made public about a vulnerability until it is
+formally announced at the end of this process. That means, for example that a
+bug tracker entry must NOT be created to track the issue since that will make
+the issue public and it should not be discussed on any of the project's public
+mailing lists. Also messages associated with any commits should not make
+any reference to the security nature of the commit if done prior to the public
+announcement.
+
+- The person discovering the issue, the reporter, reports the vulnerability
+  privately to curl-security@haxx.se. That's an email alias that reaches a
+  handful of selected and trusted people.
+
+- Messages that do not relate to the reporting or managing of an undisclosed
+  security vulnerability in curl or libcurl are ignored and no further action
+  is required.
+
+- A person in the security team sends an e-mail to the original reporter to
+  acknowledge the report.
+
+- The security team investigates the report and either rejects it or accepts
+  it.
+
+- If the report is rejected, the team writes to the reporter to explain why.
+
+- If the report is accepted, the team writes to the reporter to let him/her
+  know it is accepted and that they are working on a fix.
+
+- The security team discusses the problem, works out a fix, considers the
+  impact of the problem and suggests a release schedule. This discussion
+  should involve the reporter as much as possible.
+
+- The release of the information should be "as soon as possible" and is most
+  often synced with an upcoming release that contains the fix. If the
+  reporter, or anyone else, thinks the next planned release is too far away
+  then a separate earlier release for security reasons should be considered.
+
+- Write a security advisory draft about the problem that explains what the
+  problem is, its impact, which versions it affects, solutions or
+  workarounds, when the release is out and make sure to credit all
+  contributors properly.
+
+- Request a CVE number from distros@openwall.org[1] when also informing and
+  preparing them for the upcoming public security vulnerability announcement -
+  attach the advisory draft for information. Note that 'distros' won't accept
+  an embargo longer than 19 days.
+
+- Update the "security advisory" with the CVE number.
+
+- The security team commits the fix in a private branch. The commit message
+  should ideally contain the CVE number. This fix is usually also distributed
+  to the 'distros' mailing list to allow them to use the fix prior to the
+  public announcement.
+
+- At the day of the next release, the private branch is merged into the master
+  branch and pushed. Once pushed, the information is accessible to the public
+  and the actual release should follow suit immediately afterwards.
+
+- The project team creates a release that includes the fix.
+
+- The project team announces the release and the vulnerability to the world in
+  the same manner we always announce releases. It gets sent to the
+  curl-announce, curl-library and curl-users mailing lists.
+
+- The security web page on the web site should get the new vulnerability
+  mentioned.

+
+SSL problems
+
+  First, let's establish that we often refer to TLS and SSL interchangeably as
+  SSL here. The current protocol is called TLS, it was called SSL a long time
+  ago.
+
+  There are several known reasons why a connection that involves SSL might
+  fail. This is a document that attempts to details the most common ones and
+  how to mitigate them.
+
+CA certs
+
+  CA certs are used to digitally verify the server's certificate. You need a
+  "ca bundle" for this. See lots of more details on this in the SSLCERTS
+  document.
+
+CA bundle missing intermediate certificates
+
+  When using said CA bundle to verify a server cert, you will experience
+  problems if your CA cert does not have the certificates for the
+  intermediates in the whole trust chain.
+
+SSL version
+
+  Some broken servers fail to support the protocol negotiation properly that
+  SSL servers are supposed to handle. This may cause the connection to fail
+  completely. Sometimes you may need to explicitly select a SSL version to use
+  when connecting to make the connection succeed.
+
+  An additional complication can be that modern SSL libraries sometimes are
+  built with support for older SSL and TLS versions disabled!
+
+SSL ciphers
+
+  Clients give servers a list of ciphers to select from. If the list doesn't
+  include any ciphers the server wants/can use, the connection handshake
+  fails.
+
+  curl has recently disabled the user of a whole bunch of seriously insecure
+  ciphers from its default set (slightly depending on SSL backend in use).
+
+  You may have to explicitly provide an alternative list of ciphers for curl
+  to use to allow the server to use a WEAK cipher for you.
+
+  Note that these weak ciphers are identified as flawed. For example, this
+  includes symmetric ciphers with less than 128 bit keys and RC4.
+
+  References:
+
+  http://tools.ietf.org/html/draft-popov-tls-prohibiting-rc4-01
+  
+Allow BEAST
+
+  BEAST is the name of a TLS 1.0 attack that surfaced 2011. When adding means
+  to mitigate this attack, it turned out that some broken servers out there in
+  the wild didn't work properly with the BEAST mitigation in place.
+
+  To make such broken servers work, the --ssl-allow-beast option was
+  introduced. Exactly as it sounds, it re-introduces the BEAST vulnerability
+  but on the other hand it allows curl to connect to that kind of strange
+  servers.

-1.6 progress callback without doubles
+1.6 Modified buffer size approach
 
- The progress callback was introduced way back in the days and the choice to
- use doubles in the arguments was possibly good at the time. Today the doubles
- only confuse users and make the amounts less precise. We should introduce
- another progress callback option that take precedence over the old one and
- have both co-exist for a forseeable time until we can remove the double-using
- one.
+ Current libcurl allocates a fixed 16K size buffer for download and an
+ additional 16K for upload. They are always unconditionally part of the easy
+ handle. If CRLF translations are requested, an additional 32K "scratch
+ buffer" is allocated. A total of 64K transfer buffers in the worst case.
 
-1.7 Happy Eyeball dual stack connect
+ First, while the handles are not actually in use these buffers could be freed
+ so that lingering handles just kept in queues or whatever waste less memory.
 
- In order to make alternative technologies not suffer when transitioning, like
- when introducing IPv6 as an alternative to IPv4 and there are more than one
- option existing simultaneously there are reasons to reconsider internal
- choices.
+ Secondly, SFTP is a protocol that needs to handle many ~30K blocks at once
+ since each need to be individually acked and therefore libssh2 must be
+ allowed to send (or receive) many separate ones in parallel to achieve high
+ transfer speeds. A current libcurl build with a 16K buffer makes that
+ impossible, but one with a 512K buffer will reach MUCH faster transfers. But
+ allocating 512K unconditionally for all buffers just in case they would like
+ to do fast SFTP transfers at some point is not a good solution either.
 
- To make libcurl do blazing fast IPv6 in a dual-stack configuration, this needs
- to be addressed:
+ Dynamically allocate buffer size depending on protocol in use in combination
+ with freeing it after each individual transfer? Other suggestions?
 
-    http://tools.ietf.org/html/rfc6555
+1.7 Detect when called from within callbacks
+
+ We should set a state variable before calling callbacks, so that we

+
+ 1.5 See the Response
+
+  By default curl sends the response to stdout. You need to redirect it

+
 2. URL
 
+ 2.1 Spec
+
  The Uniform Resource Locator format is how you specify the address of a
  particular resource on the Internet. You know these, you've seen URLs like
- http://curl.haxx.se or https://yourbank.com a million times.
+ http://curl.haxx.se or https://yourbank.com a million times. RFC 3986 is the
+ canonical spec.
 
-3. GET a page
+ 2.2 Host
+
+ The host name is usually resolved using DNS or your /etc/hosts file to an IP
+ address and that's what curl will communicate with. Alternatively you specify
+ the IP address directly in the URL instead of a name.
+
+ For development and other trying out situation, you can point out a different
+ IP address for a host name than what would otherwise be used, by using curl's
+ --resolve option:
+
+      curl --resolve www.example.org:80:127.0.0.1 http://www.example.org/
+ 
+ 2.3 Port number
+
+ Each protocol curl supports operate on a default port number, be it over TCP
+ or in some cases UDP. Normally you don't have to take that into
+ consideration, but at times you run test servers on other ports or
+ similar. Then you can specify the port number in the URL with a colon and a
+ number immediately following the host name. Like when doing HTTP to port
+ 1234:
+
+      curl http://www.example.org:1234/
+
+ The port number you specify in the URL is the number that the server uses to
+ offer its services. Sometimes you may use a local proxy, and then you may
+ need to specify that proxy's port number separate on what curl needs to
+ connect to locally. Like when using a HTTP proxy on port 4321:
+
+      curl --proxy http://proxy.example.org:4321 http://remote.example.org/
+
+ 2.4 User name and password
+
+ Some services are setup to require HTTP authentication and then you need to
+ provide name and password which then is transferred to the remote site in
+ various ways depending on the exact authentication protocol used.
+
+ You can opt to either insert the user and password in the URL or you can
+ provide them separately:
+
+      curl http://user:password@example.org/
+
+ or
+
+      curl -u user:password http://example.org/
+
+ You need to pay attention that this kind of HTTP authentication is not what
+ is usually done and requested by user-oriented web sites these days. They
+ tend to use forms and cookies instead.
+
+ 2.5 Path part
+
+ The path part is just sent off to the server to request that it sends back
+ the associated response. The path is what is to the right side of the slash
+ that follows the host name and possibly port number.

+Options start with one or two dashes. Many of the options require an addition
+value next to it.
+
+The short "single-dash" form of the options, -d for example, may be used with
+or without a space between it and its value, although a space is a recommended
+separator. The long "double-dash" form, --data for example, requires a space
+between it and its value.

+Short version options that don't need any additional values can be used

+The pausing of transfers does not work with protocols that work without

 .SH AVAILABILITY
 This function was added in libcurl 7.18.0. Before this version, there was no

+.SH "USAGE WITH THE MULTI-SOCKET INTERFACE"
+Before libcurl 7.32.0, when a specific handle was unpaused with this function,
+there was no particular forced rechecking or similar of the socket's state,
+which made the continuation of the transfer get delayed until next
+multi-socket call invoke or even longer. Alternatively, the user could

+performance penalty.

+Starting in libcurl 7.32.0, unpausing a transfer will schedule a timeout
+trigger for that handle 1 millisecond into the future, so that a
+curl_multi_socket_action( ... CURL_SOCKET_TIMEOUT) can be used immediately
+afterwards to get the transfer going again as desired.
