POTENTIAL INCOMPATIBILITY
Own Id: OTP-18641 Aux Id: PR-7316
The httpd module has been extended with an API for simple serving directory content over HTTP. With this change, the current working directory can be served like this:

Own Id: OTP-18472 Aux Id: DAFH-1592

Improvements and New Features

Adds more type information to the inets app, thus improving the errors that static analysis tools can detect.
The addition of type information to records and the updates to function heads help static analysis tools to understand that some values in the records cannot be 'undefined', thus making static tools to type check correctly more modules in the inets app
Own Id: OTP-18390 Aux Id: PR-6661
Replace size/1 with either tuple_size/1 or byte_size/1
The size/1 BIF is not optimized by the JIT, and its use can result in worse types for Dialyzer.
When one knows that the value being tested must be a tuple, tuple_size/1 should always be preferred.
When one knows that the value being tested must be a binary, byte_size/1 should be preferred. However, byte_size/1 also accepts a bitstring (rounding up size to a whole number of bytes), so one must make sure that the call to byte_size/ is preceded by a call to is_binary/1 to ensure that bitstrings are rejected. Note that the compiler removes redundant calls to is_binary/1, so if one is not sure whether previous code had made sure that the argument is a binary, it does not harm to add an is_binary/1 test immediately before the call to byte_size/1.

Integrate elliptic curve contribution from Andreas Schultz
In order to be able to support elliptic curve cipher suites in SSL/TLS, additions to handle elliptic curve infrastructure has been added to public_key and crypto.
This also has resulted in a rewrite of the crypto API to gain consistency and remove unnecessary overhead. All OTP applications using crypto has been updated to use the new API.
Impact: Elliptic curve cryptography (ECC) offers equivalent security with smaller key sizes than other public key algorithms. Smaller key sizes result in savings for power, memory, bandwidth, and computational cost that make ECC especially attractive for constrained environments.

Inets 5.5

Fixed Bugs and Malfunctions

[httpc] If a request times out (not connect timeout), the handler process exited (normal) but neglected to inform the manager process. For this reason, the manager did not clean up the request table., resulting in a memory leak. Also the manager did not create a monitor for the handler, so in an unforeseen handler crash, this could also create a memory leak.

[httpc] - Memory leak plugged. The profile manager never cleaned up in its handler database. This meant that with each new request handler, another entry was created that was never deleted. Eventually the request id counter (used as a key) would wrap, but the machine would most likely run out of memory before that happened.

[httpd] - Issues with ESI erl_script_timeout.
- The erl_script_timeout config option is ducumented as a number of seconds. But when parsing the config, in the new format (not a config file), it was handled as if in number of milliseconds.
- When the erl-script-timeout time was exceeded, the server incorrectly marked the answer as sent, thereby leaving client hanging (with an incomplete answer). This has been changed, so that now the socket will be closed.

[httpc] Fix bug crafting Host header when port is not 80.
The host header should include the port number as well as the host name when making a request to a server listening on a port other than the HTTP default of 80. Currently, only the host name is included. This is important to make the http client more compliant with the HTTP specification.

[httpc|httpd] http_chunk data handling/passing improvement.
This is a modification to the http_chunk module to forward any full chunk received, regardless of whether the size field for the following chunk has been received yet. This allows http_chunk to be used in situations where a long term HTTP connection is used to send periodic status updates as individual chunks. Previously a given chunk would not be forwarded to the client process until the size for the next chunk had been read which rendered the module difficult to use for the scenario described.

[httpc] Several more or less critical fixes:
- Initial call between the httpc manager and request handler was synchronous.
  When the manager starts a new request handler, this is no longer a synchronous operation. Previously, the new request handler made the connection to the server and issuing of the first request (the reason for starting it) in the gen_server init function. If the connection for some reason "took some time", the manager hanged, leaving all other activities by that manager also hanging.
As a side-effect of these changes, some modules was also renamed, and a new api module, httpc, has been introduced (the old module http is not removed, but is now just wrapper for httpc).

[ftpc] - Start of the FTP client has been changed in the following way:
- It is now also possible to start a standalone FTP client process using the re-introduced ftp:open/2 function.
  This is an alternative to starting the client using the inets service framework.
  The old ftp:open/1, undocumented, function, caused the client to be hooken into the inets service supervision framework. This is no longer the case.
  * POTENTIAL INCOMPATIBILITY *
- Previously, the FTP client attempted to use IPv6, unless otherwise instructed (the ip_v6_disabled flag), and only used IPv4 if this did not work. This has now been changed.
  A new option, ipfamily, has been introduced, with the default value inet (IPv4).
  See ftp:open/2 for more info.

[ftpc] - The ftp:ls/2 function (LIST command) and the ftp:nlist/2 function (NLST command) with wildcards did not work properly.
These functions is documented as working on directories, but this is actually not according the standard. The LIST and NLST commands are specified to operate on a directory or other group of files, or a file.
Previously, an attempt was made to check if the listing returned by the server was actually an error message. This was done by changing remote directory (cd) into the (assumed) "directory". This may work if Pathname was actually a directory, but as this is not always the case, this test does not work. Instead, we now return the actual server result and leave the interpretation to the caller.

[httpc] - Raise condition. When http:request is called and httpc_manager selects a session where there's already a pending request, then the connection handler for that session effectively resets its parser, readying it for the response to the second request. But if there are still some inbound packets for the response to the first request, things get confused.

Improvements and New Features

[httpd] - When starting inets (the web-server) and supplying a descriptor on the command line (example: erl -httpd_8888 <descriptor>) it is now possible to specify which ip-family to use: inet | inet6 | inet6fb4.
Example: erl -httpd_8888 10|inet6
When starting the web-server either using a file with property list (the proplist_file) or a an property list, using the ipfamily option: {ipfamily, inet | inet6 | inet6fb4}.
Finally, when starting the web-server using the classical apache-style config file, the BindAddress directive has been augmented to allow the specification of the IpFamily: BindAddress blirk.ericsson.se|inet
Default is inet6fb4 which emulates the behaviour of the previous version.
