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.
When actually fetching the data, bigint (unsigned) column values are
returned as integers on LLP64 architectures, so their pdo_type has to
be PDO::PARAM_INT accordingly.
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
