Set TCP_USER_TIMEOUT to cap (ms) how long TCP will wait for ACKs on in-flight data before aborting the connection; prevents stuck/half-open sessions and enables faster failover vs default retransmission timeouts. Co-authored-by: David Carlier <devnexen@gmail.com> close GH-20708

|
========================================
|
|
1. Backward Incompatible Changes
|
|
========================================
|
|
|
|
- Phar:
|
|
. Invalid values now throw in Phar::mungServer() instead of being silently
|
|
ignored.
|
|
|
|
========================================
|
|
2. New Features
|
|
========================================
|
|
|
|
- Core:
|
|
. It is now possible to use reference assign on WeakMap without the key
|
|
needing to be present beforehand.
|
|
|
|
- Intl:
|
|
. Added IntlNumberRangeFormatter class to format an interval of two numbers with a given skeleton, locale, IntlNumberRangeFormatter::COLLAPSE_AUTO, IntlNumberRangeFormatter::COLLAPSE_NONE, IntlNumberRangeFormatter::COLLAPSE_UNIT, IntlNumberRangeFormatter::COLLAPSE_ALL collapse and
|
|
IntlNumberRangeFormatter::IDENTITY_FALLBACK_SINGLE_VALUE, IntlNumberRangeFormatter::IDENTITY_FALLBACK_APPROXIMATELY_OR_SINGLE_VALUE, IntlNumberRangeFormatter::IDENTITY_FALLBACK_APPROXIMATELY and
|
|
IntlNumberRangeFormatter::IDENTITY_FALLBACK_RANGE identity fallbacks.
|
|
It is supported from icu 63.
|
|
|
|
- Phar:
|
|
. Overriding the getMTime() and getPathname() methods of SplFileInfo now
|
|
influences the result of the phar buildFrom family of functions.
|
|
This makes it possible to override the timestamp and names of files.
|
|
|
|
- Streams:
|
|
. Added stream socket context option so_reuseaddr that allows disabling
|
|
address reuse (SO_REUSEADDR) and explicitly uses SO_EXCLUSIVEADDRUSE on
|
|
Windows.
|
|
|
|
========================================
|
|
3. Changes in SAPI modules
|
|
========================================
|
|
|
|
========================================
|
|
4. Deprecated Functionality
|
|
========================================
|
|
|
|
========================================
|
|
5. Changed Functions
|
|
========================================
|
|
|
|
- Phar:
|
|
. Phar::mungServer() now supports reference values.
|
|
|
|
- Zip:
|
|
. ZipArchive::extractTo now raises a TypeError for the
|
|
files argument if one or more of the entries is not
|
|
a string.
|
|
|
|
========================================
|
|
6. New Functions
|
|
========================================
|
|
|
|
- Standard:
|
|
. `clamp()` returns the given value if in range, else return the nearest bound.
|
|
RFC: https://wiki.php.net/rfc/clamp_v2
|
|
|
|
========================================
|
|
7. New Classes and Interfaces
|
|
========================================
|
|
|
|
========================================
|
|
8. Removed Extensions and SAPIs
|
|
========================================
|
|
|
|
========================================
|
|
9. Other Changes to Extensions
|
|
========================================
|
|
|
|
- Hash:
|
|
. The bundled version of xxHash was upgraded to 0.8.2.
|
|
|
|
========================================
|
|
10. New Global Constants
|
|
========================================
|
|
|
|
- Sockets:
|
|
. TCP_USER_TIMEOUT (Linux only).
|
|
|
|
========================================
|
|
11. Changes to INI File Handling
|
|
========================================
|
|
|
|
- Mysqli:
|
|
. mysqli.default_port now checks the validity of the value which should be
|
|
between 0 and 65535 included.
|
|
|
|
- Opcache:
|
|
. opcache.jit_debug accepts a new flag: ZEND_JIT_DEBUG_TRACE_EXIT_INFO_SRC.
|
|
When used along with ZEND_JIT_DEBUG_TRACE_EXIT_INFO, the source of exit
|
|
points is printed in exit info output, in debug builds.
|
|
|
|
- Mbstring:
|
|
. The mbstring.detect_order INI directive now updates the internal detection
|
|
order when changed at runtime via ini_set(). Previously, runtime changes
|
|
using ini_set() did not take effect for mb_detect_order(). Setting the
|
|
directive to NULL or an empty string at runtime now leaves the previously
|
|
configured detection order unchanged.
|
|
|
|
========================================
|
|
12. Windows Support
|
|
========================================
|
|
|
|
========================================
|
|
13. Other Changes
|
|
========================================
|
|
|
|
========================================
|
|
14. Performance Improvements
|
|
========================================
|
|
|
|
- Core:
|
|
. `printf()` using only `%s` and `%d` will be compiled into the equivalent
|
|
string interpolation, avoiding the overhead of a function call and repeatedly
|
|
parsing the format string.
|
|
. Arguments are now passed more efficiently to known constructors (e.g. when
|
|
using new self()).
|
|
|
|
- DOM:
|
|
. Made splitText() faster and consume less memory.
|
|
|
|
- JSON:
|
|
. Improve performance of encoding arrays and objects.
|
|
|
|
- Standard:
|
|
. Improved performance of array_fill_keys().
|
|
. Improved performance of array_map() with multiple arrays passed.
|
|
. Improved performance of array_unshift().
|
|
. Improved performance of array_walk().
|
|
. Improved performance of intval('+0b...', 2) and intval('0b...', 2).
|
|
. Improved performance of str_split().
|
|
|
|
- Zip:
|
|
. Avoid string copies in ZipArchive::addFromString().
