Notice: SVN will reject PHP with errors

When you commit PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. https://www.php.net/manual/en/preface.php. files, the repository will no longer let you commit them if they have PHP syntax errors. Such an error would make the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party fail when it tried to load the file anyway, so think of this as a ‘for your own protection’ kind of thing.

So if you get a kick-back error like this:

Error: Commit failed (details follow): Error: Commit blocked by pre-commit hook (exit code 1) with output: Error: PHP Parse error: syntax error, unexpected end of file in - on line 1234 Error: Error: *********************************** Error: PHP error in: really-cool/tags/1.0/really-cool.php: Error: Errors parsing really-cool/tags/1.0/really-cool.php Error: *********************************** Error: This error was generated by a custom hook script on the Subversion server. Error: Please contact your server administrator for help with resolving this issue. Completed!:

you need to fix the syntax errors in the file before uploading.

That’s great! I’ve seen this happen occasionally, and its no fun for the developer or the pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

Please note: This currently does a PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. https://www.php.net/manual/en/preface.php. 5.4 syntax check. Please be careful if you are using 5.3 or 5.4-specific language features, like namespaces, closures, short array or ternary syntaxes, etc. These will break sites running PHP 5.2 (which is a majority of sites).

This has actually been enabled for many months.

  Hi @nacin can you elaborate on “ternary syntaxes” that you’ve mentioned ?!

    A ternary operator in PHPPHP PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. https://www.php.net/manual/en/preface.php. looks like this:
    
    ( expression1 ) ? expression2 : expression3
    
    If the expression1 evaluates to true, then the result is expression2. If not, then the result is expression3. A simple example:
    
    $variable = ( $a > $b ) ? ‘A is greater than B’ : ‘A is not greater than B’;
    
    Obviously the expressions can be more complex than this.
    
    Now, as of PHP 5.3, there is a shorthand ternary operation that works like this:
    
    ( expression1 ) ?: expression3
    
    This basically evaluates expression1, and if it’s equivalent to true, then the value of expression1 is returned. If not, then expression3 is returned. This is useful in either/or cases.
    
    Say you have a function returns a string or false. You want to replace the false case with some other string, like “fake”. This will do it:
    
    $var = ( getString() ) ?: ‘fake’;
    
    However, the ?: shorthand is PHP 5.3 only. In 5.2 it will cause a syntax error. You could do the same thing in 5.2 code without the shorthand:
    
    $var = ( getString() ) ? getString() : ‘fake’;
    
    Or if you needed to not call getString twice, by using a separate call:
    
    $var = getString();
    $var = ( $var ) ? $var : ‘fake’;
    
    If you’re using 5.3-only code of any sort, make sure that your pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party checks for 5.2 cases (still more than half of all installs) and fails gracefully. Or just write 5.2 compliant syntax. There’s nothing in 5.3 and up that’s actually required for most cases.

  It was actually broken (disabled) until ~11 days ago

Thanks for the info Samuel

Would love to see this also support “warnings” and “notices” 😀

This pre commit hook triggers on code generated by Composer v1.2 For example:

Looking at the code, I see nothing wrong with it:

    ...
    public static $prefixDirsPsr4 = array (
        'Mivhak\\' => 
        array (
            0 => __DIR__ . '/../..' . '/includes',
        ),
    );
    ...
