While __php_mempcpy is only used by ext/standard/crypt_sha*, the
mempcpy "pattern" is used everywhere.
This commit removes __php_mempcpy, adds zend_mempcpy and transforms
open-coded parts into function calls.
Unless stringified results are requested, we need to parse large
bigints as unsigned, to avoid wrap-around behavior.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
When row data split across multiple packets, allocate a temporary
buffer that can be reallocated, and only copy into the row buffer
pool arena once we know the final size. This avoids quadratic
memory usage for very large results.
(cherry picked from commit 1fc4c89214)
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
If the ZEROFILL flag is set for a field, do not convert it into
an integer (text protocol) or convert it explicitly into a padded
string (binary protocol).
This API only works in very limited circumstances -- relying on
it will invariably lead to leaks. The correct way to "free" something
from the pool is to use the checkpoint API.

Rather than segfaulting because sname is missing lateron, report
a FAIL here. As this indicates a server bug, the errors is reported
as an out of band warning, rather than a client error.
This fixes the PHP side of bug #80713.
We must not use the locale dependent `atof()`, but instead use the
(hopefully) locale independent `zend_strtod()`, when converting string
representations of floating point numbers which are sent by the server.

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
