[httpc] - If a request times out (not during connect), 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 unforseen 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] - Allow users to pass socket options to the transport module when making requests.

[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.

[httpd] The server did not fully support the documented module callback api. Specifically, the load function should be able to return the atom ok, but this was not accepted.

[ftpc] - The ls/2 function (LIST command) and the 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.

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.

[tftp] If a callback (which performs the file access in the TFTP server) takes too long time (more than the double TFTP timeout), the server will abort the connection and send an error reply to the client. This implies that the server will release resources attached to the connection faster than before. The server simply assumes that the client has given up.

[tftp] If the TFTP server receives yet another request from the same client (same host and port) while it already has an active connection to the client, it will simply ignore the new request if the request is equal with the first one (same filename and options). This implies that the (new) client will be served by the already ongoing connection on the server side. By not setting up yet another connection, in parallel with the ongoing one, the server will consumer lesser resources.

[tftp] netascii mode is now supported when the client/server has native ascii support (Windows). The new optional parameter native_ascii in the tftp_binary and tftp_file callback modules can be used to override the default behavior.

[tftp] Yet another callback module has been added in order to allow customized handling of error, warning and info messages. See the new configuration parameter, logger.
