When fetching into objects, we need to create object style hash tables,
i.e. where numeric column names are stored as string keys instead of
integer keys. Instead of the slightly more efficient alternative to
create the desired hash table in the first place, we go for the more
readable implementation and convert the array style hash table using
`zend_symtable_to_proptable()`.

- 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.
Use the proper error reporting mechanism rather than throwing a
warning. This requires something of a hack because we don't have
direct access to the connection object at this point.
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 |
Previously this just assumed that the value was of a certain type.
I'm doing this in a generic way that checks against the declared
property type -- the handler function can then assume the value
to be of the correct type.
* allow the user to specify a folder where files that can be sent
via LOAD DATA LOCAL can exist
* add mysqli.local_infile_directory for mysqli
(ignored if mysqli.allow_local_infile is enabled)
* add PDO::MYSQL_ATTR_LOCAL_INFILE_DIRECTORY for pdo_mysql
(ignored if PDO::MYSQL_ATTR_LOCAL_INFILE is enabled)
* add related tests
* fixes for building with libmysql 8.x
* small improvement in existing tests
* update php.ini-[development|production] files

Rename MYSQLI_REFRESH_SLAVE to MYSQLI_REFRESH_REPLICA in line with
upstream change in MySQL. The old name is retained for
backwards-compatibility reasons, and may be deprecated/removed in
the future.
Closes GH-6632.
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.
From an engine perspective, named parameters mainly add three
concepts:
* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.
