buildlink2.mk files back into the main trunk. This provides sufficient
buildlink2 infrastructure to start merging other packages from the
buildlink2 branch that have already been converted to use the buildlink2
framework.
- Fixed start up failure when mm save handler is used and there is multiple
SAPIs are working at the same time. (Yasuo)
- Fixed a buffer overflow in the RFC-1867 file upload code (Stefan)
<===> SECURITY NOTE <===>
Note that the buffer overflow fix is a major security fix. Quoting from
the security advisory at:
http://security.e-matters.de/advisories/012002.html
"PHP supports multipart/form-data POST requests (as described in RFC1867)
known as POST fileuploads. Unfourtunately there are several flaws in the
php_mime_split function that could be used by an attacker to execute
arbitrary code. During our research we found out that not only PHP4 but
also older versions from the PHP3 tree are vulnerable.
[...]
"If you are running PHP 4.0.3 or above one way to workaround these bugs is
to disable the fileupload support within your php.ini (file_uploads = Off).
If you are running php as module keep in mind to restart the webserver.
Anyway you should better install the fixed or a properly patched version to
be safe."
- Fixed bug that caused crashes or error notices on shutdown on threaded
platforms. (Zeev)
- Fixed bug in gmmktime() which was one hour off during standard time -
bug #9878. Patch by bfoddy@mediaone.net. (jmoore)
- Fixed a bug where the is_file() family of functions would in-correctly give
an error when they were given filenames that didn't exist. (Sterling)
- Fixed a bug in the strtotime() function where it was incorrectly recognizing
GMT +0100 and GMT -0100. (Derick)
- Introduced a new $_REQUEST array, which includes any GET, POST or COOKIE
variables. Like the other new variables, this variable is also available
regardless of the context.
- Introduced $_GET, $_POST, $_COOKIE, $_SERVER and $_ENV variables, which
deprecate the old $HTTP_*_VARS arrays. In addition to be much shorter to
type - these variables are also available regardless of the scope, and
there's no need to import them using the 'global' statement.
Other relevant changes include:
- Bug fixes to prevent crashes on unexpected input.
- Huge performance improvements, especially in thread-safe code.
- Introduced extension version numbers.
- Added support for single dimensional SafeArrays and Enumerations.
Added an is_enum() function to check if a component implements an
enumeration.
- Improved speed of the serializer/deserializer.
- Floating point numbers are better detected when converting from strings.
- Added import_request_variables(), to allow users to safely import form
variables to the global scope
- Add config option (always_populate_raw_post_data) which when enabled
will always populate $HTTP_RAW_POST_DATA regardless of the post mime
type
- Added getmygid() and safe_mode_gid ini directive to allow safe mode to do
a gid check instead of a uid check.
- Assigning to a string offset beyond the end of the string now automatically
increases the string length by padding it with spaces, and performs the
assignment.
This value may be customized in various ways:
PKG_SYSCONFBASE is the main config directory under which all package
configuration files are to be found.
PKG_SYSCONFSUBDIR is the subdirectory of PKG_SYSCONFBASE under which the
configuration files for a particular package may be found.
PKG_SYSCONFDIR.${PKGBASE} overrides the value of ${PKG_SYSCONFDIR} for a
particular package.
Users will typically want to set PKG_SYSCONFBASE to /etc, or accept the
default location of ${PREFIX}/etc.
This obsoletes the use of CONFDIR, which was active for only 6 days, so no
need to have a workaround to still accept old CONFDIR settings.
bsd.pkg.install.mk:
* Remove old DEINSTALL/INSTALL scripts.
* Move some text printed at POST-INSTALL time into the MESSAGE file.
* Adjust rc.d scripts to respect rc.conf settings, so that the
script may be directly copied into /etc/rc.d.
into the apache mod_php.so DSO.
PHP4_CONFIGURE_ARGS should contain GNU configure options, a complete
list of which may be found at:
http://www.php.net/manual/en/install.configure.php
Note that this is generally not needed as many of the extensions (session,
mysql, pgsql, pcre) may be dynamically loaded, and are separately packaged
in pkgsrc.
- Bug fixes (memory leaks and other errors)
- Made $HTTP_SESSION_VARS['foo'] and $foo be references to the same value
when register_globals is on. (Andrei)
- Added is_callable() function that can be used to find out whether
its argument is a valid callable construct. (Andrei)
- Added pg_last_notice() function. (Rasmus from suggestion by Dirk@rackspace.com)
- Added support to getimagesize to return dimensions of BMP and PSD
files. (Derick)
- Added Japanese multibyte string functions support. (Rui)
- Added key_exists() to check if a given key or index exists in an
array or object. (David Croft)
- Added -C command-line option to avoid chdir to the script's directory. (Stig)
- printf argnum (parameter swapping) support. (Morten Poulsen, Rasmus)
- Modified get_parent_class() and get_class_methods() to accept a class name as
well as a class instance. (Andrei, Zend Engine)
- Added array_map() function that applies a callback to the elements
of given arrays and returns the result. It can also be used with a
null callback to transpose arrays. (Andrei)
- Added array_filter(), which allows filtering of array elements via
the specified callback. (Andrei)
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
file. It defaults to ${LOCALBASE}/etc.
* Move example configuration files to ${PREFIX}/share/examples/php.
* Ensure we export symbols when linking loadable shared object files
during extension module creation.
