Things to do or at least think about doing in the future. Name in
parenthesis means that person has taken on this project.

Zend
----
    * Allow foreach ($array as $k => list($a, $b)) syntax for multi
      dimensional arrays.
    * Look at replacing c-lib call tolower().
    * Make hash API functions work with HASH_OF() to save time.
    * Add configure test to determine if dlsym() requires underscore and set
      DLSYM_NEEDS_UNDERSCORE accordingly. Perl and zsh have it in configure, 
      for example. (DONE?)
    * Native large number support (probably with GNU GMP)
    * Const'ify APIs. Right now, many functions leave parameters untouched,
      but don't declare those as const. This makes interaction with other
      interfaces difficult which pass const parameters to us.


global
------
    * Make sure that all ZTS globals get destructed. Most ts_allocate_id()
      calls should have a dtor entry.
    * on some platforms unimplemented function will just do nothing 
      (e.g. symlink) they should print a warning or not even be defined!
      (DONE ?)
    * --enable-all in configure. (--enable-shared=max ...)
    * make configure print out a summary when it's done (like XEmacs)
    * replace standard functions which work on static data with 
      reentrancy-safe functions (DONE?).
    * make SAPI conform to CGI/1.1. Currently, all SAPI modules
      define REMOTE_ADDR etc. themselves and reach only various level
      of compliance.
    * see what functions might need to be changed to use HashPosition, so
      that the internal array pointer is not affected.
    * Move most extensions and PEAR packages out of the PHP CVS tree,
      include them again during release packaging.

    Other
    * use thread-safe resolver functions (either require BIND 8 or adns).
    * implement javadoc based function docs template system.
    * provide optional IPv6 support (seems to be done?).
    * find a better way to implement script timeouts. SIGVTALRM is used
      by some POSIX threads implementations (i.e. OpenBSD) and is not
      available in ZTS mode.
    * Implement flush feature suitable for nested output buffers.

Streams
-------
    * Route filestat.c through the wrapper layer; isolate the statcache code
      so that it is independent of php functions and can be applied to any
      stream/path.
    * Implement generalized connection pool for stated protocols such as
      ftp and http/1.1 (using keep-alive) to avoid having to negotiate
      new command/request stream for each subsequent call; Possibly store 
      resources in contexts (creating a default context if necessary) to 
      allow segmentation of connection pools.
    * Add a method to take ownership of the memory buffer in memory streams so
      that generating string values for zvals doesn't require an estrdup.
    * bundle and use curl lib for fopen wrapper.

documentation
-------------
    * Add remarks in the documentation which functions are not implemented 
      on win32. 
    * Add remarks in the documentation which functions are not binary-safe.
    * Update curl documentation (DONE?)
    * Add developer documentation.
    * Add detailed documentation for Java extension.

ext/bz2
-------
    * Add an ini directive to specify the size of decompression buffer.
      The default 4k is too small for large files and also requires much time
      for decompression. 40k is suitable for such files, however it may be too
      much under certain environments. There should be appropriate default
      settings for the various SAPI modules (e.g. apache and cli).

ext/curl
--------
    * Have a warning scheme for when people use unsupported features.

ext/oci8
--------
    * All OCIFetch*() functions should return 0 for no more data and false on 
      error.
    * Have a flag that trims trailing spaces from CHAR fields on retrieval.
    * Make allow_call_time_pass_reference=Off working.
    * For additional todo information, see oci8.c, in ext/oci8

ext/odbc
--------
    For PHP 4.3.0:
    * update all php_error calls to php_error_docref where valid
    * integrate EXPERIMENTAL ODBC update for use in PHP 5.0, use for
      testing purposes only.

    For PHP 5.0.0
    * Activate EXPERIMENTAL ODBC codebase update

ext/pcre
--------
    * Allow user to set PCRE_NOTEMPTY, PCRE_ANCHORED at execution time, maybe

ext/pcntl
---------
    * Change internal callback handler to use TICKS
    * Remove all zend_extension code
    * Add object callback support to pcntl_signal()

ext/pgsql
---------
    For PHP 4.3.0:
    * Add pg_metadata() with metadata cache feature.
    * Add pg_convert() to check and convert array value for query.
    * Add pg_insert/pg_update/pg_delete/pg_select for simple query.

ext/session
-----------
    For PHP 4.3.0:
    * session_abort() to abort session. ie: Do not save session data.
    * Allow unset($_SESSION) or unset($HTTP_SESSION_VARS) to unset
      session vars regardless of register_globals setting.

    Other:
    * Maybe implement finer-grained session variables that could be 
      locked individually.
    * Write a network-transparent storage back-end with fallover
      facilities
    * Provide a callback facility which is executed upon encountering
      an unknown class name during deserialization

ext/standard
------------
    * Add a version number to data serialized via serialize().
    * Possibly modify parsing of GPC data to automatically create arrays if
      variable name is seen more than once.
    * Implement regex-cache for url-functions.
    * Move socket related functions to fsock.c.

ext/wddx
--------
    * See if we can support the remaining data types:
        dateTime
        binary

        http://www.wddx.org/WDDX_SDK_10a/7__References/WDDX_DTD.htm
        (Andrei)

    * implement wddx_packet_as_javascript(). (Andrei)

other cool stuff
----------------
    * PVM extension
