* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
PDO include paths can be simplified and synced as done in other
extensions: either the project root directory or the phpincludedir (for
the system installation). The 'ext' include is automatically appended
when doing phpize build. In php-src it is only present on Windows build.
The PHP_CHECK_PDO_INCLUDES is left intact working as before and checks
if PDO headers are found.
The check for the number of bound parameters was only executed if
at least one was bound. We should also error if nothing was bound.
With mysqlnd, mysqlnd itself ended up emitting an error, but with
libmysqlclient this error condition would not be detected.
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.

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.
Instead of requiring the type to be determined in advance by the
describer function and then requiring get_col to return a buffer
of appropriate type, allow get_col to return an arbitrary zval.
See UPGRADING.INTERNALS for a more detailed description of the
change.
This makes the result fetching simpler, more efficient and more
flexible. The general possibility already existed via the special
PDO_PARAM_ZVAL type, but the usage was very inconvenient and/or
inefficient. Now it's possible to easily implement behavior like
"return int if it fits, otherwise string" and to avoid any kind
of complex management of temporary buffers.
This also fixes bug #40913 (our second highest voted bug of all
time, for some reason). PARAM_LOB result bindings will now
consistently return a stream resource, independently of the used
database driver.
I've tried my best to update all PDO drivers for this change, but
some of the changes may be broken, as I cannot test or even build
some of these drivers (in particular PDO dblib and PDO oci).
Fixes are appreciated -- a working CI setup would be even more
appreciated ;)
Previously, PDO MySQL only fetched data as native int/float if
native prepared statements were used. This patch updates PDO to
have the same behavior for emulated prepared statements, and thus
removes the largest remaining discrepancy between these two modes.
Note that PDO already has a ATTR_STRINGIFY_FETCHES option to control
whether native types are desired or not. The previous output can
be restored by enabling this option.
Most of the tests make use of that option, because this allows the
tests to work under libmysqlclient as well, which currently always
returns string results (independently of whether native or emulated
PS are used).
mysqlnd already creates interned zend_strings for us, so let's
make use of them.
This also required updating the PDO case changing code to work
with potentially shared strings. For the lowercasing, use the
optimized zend_string_tolower() implementation.
libmysqlclient added this function in version 5.5, which happens
to be the minimum we support. If we have a prepared statement,
we should use it on both mysqlnd and libmysqlclient, even if the
handling afterwards is different.
This fixes error handling with native prepared statements.
stmt->column_count gets reset before the next_rowset handler is
invoked, so we need to fetch the value from the result set instead.
Arguably PDO should be separating the destruction of the previous
result set and the switch to the next result set more cleanly...
Keep track of whether we have fully consumed all result sets,
either using nextRowset() calls or closeCursor() and skip the
attempt to consume remaining results sets during destruction in
that case.
Especiall if closeCursor() has been used, we really shouldn't
have this sort of cross-statement inference.
This was already working in all cases apart from native prepared
statements with unbuffered queries. In that case invoking
stmt_free_result() addresses the issue.
Two bugs both affecting the bug_pecl_7976.phpt test ("works with
mysqlnd" haha):
* We should not change the connection state in stmt_free_result.
This makes mysql_stmt_free_result usable under mysqlnd and
not just libmysqlclient.
* If we call mysql_stmt_free_result, we still need to consume
any outstanding result sets.
MySQL always returns a trailing empty result set for stored
procedure calls, which is used to convey status information.
The PDO MySQL implementation is presently confused about what to
do with it: If mysqlnd is used and native prepared statements are
used, this result set is skipped. In all other cases it is not
skipped. We also have quite a few XFAILed tests relating to this.
This patch normalizes (for PHP-8.0 only) the behavior towards
always retaining the empty result set. This is simply how MySQL
stored procedures work (some expletives omitted here) and we can't
distinguish this "useless" result set from an empty result of a
multi query. Multi queries are not a concern for native prepared
statements, as PDO does not allow them in that case, but they are
a concern for emulated prepared statements.
Closes GH-6497.
This has been fixed for PDO SQlite by GH-4313, however the same
issue also applied to PDO MySQL.
Move the column count setting function into the main PDO layer
(and export it) and then use it in both PDO SQLite and PDO MySQL.
If there is no result set (e.g. for upsert queries), still allow
fetching to occur without error, i.e. treat it the same way as
an empty result set.
This normalizes behavior between native and emulated prepared
statements and addresses a regression in PHP 7.4.13.
The EOF flag also gets set on error, so we always end up ignoring
errors here.
However, we should only check errors for unbuffered results. For
buffered results, this function is guaranteed not to error, and
querying the errno may return an unrelated error.
Make sure deadlock errors are properly propagated and reports in
a number of places in mysqli and PDO MySQL.
This also fixes a memory and a segfault that can occur under these
conditions.
When stored procedures are called, the "final result set is a status
result that includes no result set". Calling `::nextRowset()` on the
actual last result set should return FALSE, since there is actually no
further result set to be processed.
