Inets Release Notes

Inets 2.5.3

Improvements and new features

• It's now possible to perform runtime upgrade/downgrade

of the HTTPD server from/to 2.5.1.
The upgrade/downgrade is rather crude: An application restart!
• Further improvment of handling of lack-of-resources situations.

Fixed errors and malfunctions

• CGI related problem with executable files on win32.

A problem related to the win32 platform and cgi caused HTTPD to fail to
detect executable files if the file name (of the retrieved file)
contained a "executanle" extension (i.e. '.exe', '.com' or '.bat').
Own Id: OTP-3627
• Heavy load state incorrect.

A special heavy load listener process was created when HTTPD reaches
the heavy load state. The next request was be rejected, regardless of
the actual state at that time.
Own Id: OTP-3528

Known bugs and problems

No known problems.

Inets 2.5.2

Improvements and new features

• Now possible to run more then one HTTP server in a node listening to the same port number but different addresses.

Own Id: OTP-3493

Fixed errors and malfunctions

• Status code 404 incorrectly used instead of 500.

Own Id: OTP-3402
• Handling of lack of resources (to many open files, ...) improved.

Own Id: OTP-3403, OTP-3461
• Use of obsolete and not recommended functions removed.

Functions httpd_conf:is_directory/1 and httpd_conf:is_file/1 has changed so that when they are called with a path which is not a directory (in the first case) or file (in the second case) then the return value will be {error,FileInfo}, where FileInfo is now a file_info record according to kernel/include/file.hrl.
Own Id: OTP-3405
• Call of non-existing function 'inet:getaddr/1' in httpd_conf:load/2 Corrected.

Own Id: OTP-3457
• Call to non-existing module 'http_conf' in mod_auth:load/2. Corrected.

Own Id: OTP-3459
• An error (module mod_include) in the parsing of SHTML files could cause the handling process to crash. The reason was the reading of files was done in chunks. If a directive or comment starts at the end of a chunk but ends in the next chunk, this was taken as EOF and an exception was thrown. This exception was not handled which caused the process to crash.

Own Id: OTP-3527
• The FTP failure 'File system full' during file transfer is not handled properly.

Own Id: OTP-3268, OTP-3503

Aux Id: HA98434, seq 1151

Improvements and new features

• The authentication modules have been rewritten with support for dets, plain and mnesia authentication databases. There is also a new module called 'mod_secrity', which implements security event logging and notification. Both the mod_auth and mod_security modules have an API for the programmer that implements functions they will require to have full control over access restricted parts of a site. NOTE: The mod_auth_mnesia module does not implement the API previously found there, please see the mod_auth documentation.

Own Id: OTP-2281
Aux Id: seq 740,OTP-2273
• Support for the sockets application has been removed from INETS, use SocketType ssl or ip_comm instead.

Own Id: OTP-2848
• The HTTP server has got improved efficiency through recognition of the 'If-Modified-Since' header field.

Own Id: OTP-2870
• CGI scripts are now supported on Windows aswell as UNIX platforms.

Own Id: OTP-2915
• mod_auth now supports the 'deny from' directive.

Own Id: OTP-2982
• The HTTP server now experimentaly supports persistent connections (as defined in RFC2068). This is the first step towards HTTP/1.1 support. Enabling this feature may greatly improve performance, as the server then uses the same TCP connection for more than one HTTP request. Two new configuration directives are defined for httpd_core: KeepAlive max-requests KeepAliveTimeout seconds
