Discussion ---------- [HttpFoundation] enhance PdoSessionHandler | Q | A | ------------- | --- | Bug fix? | yes | New feature? | yes | BC breaks? | yes | Deprecations? | no | Tests pass? | yes | Fixed tickets | #5483, #2067, #2382, #9029 | License | MIT 0. [x] Continuation of locking implementation (#10908): Implement different locking strategies - `PdoSessionHandler::LOCK_TRANSACTIONAL` (default): Issues a real row lock but requires a transaction - `PdoSessionHandler::LOCK_ADVISORY`: app-level lock, safe as long as only the PdoSessionHandler accesses sessions, advantage is it does not require a transaction (not implemented for oracle or sqlsrv yet) - `PdoSessionHandler::LOCK_NONE`: basically what is was before, prone to race conditions, means the last session write wins 1. [x] Save session data as binary: Encoding session data was definitely the wrong solution. Session data is binary text (esp. when using other session.serialize_handler) that must stay as-is and thus must also be safed in a binary column. Base64 encoding session data just decreses performance and increases storage costs and is semantically wrong because it does not have a character encoding. That saving null bytes in Posgres won't work on a character column is also documented > First, binary strings specifically allow storing octets of value zero and other "non-printable" octets (usually, octets outside the range 32 to 126). Character strings disallow zero octets, and also disallow any other octet values and sequences of octet values that are invalid according to the database's selected character set encoding. http://www.postgresql.org/docs/9.1/static/datatype-binary.html#DATATYPE-BINARY-TABLE 2. [x] Implement lazy connections that are only opened when session is used by either passing a dsn string explicitly or falling back to session.save_path ini setting. Fixes #9029 3. [x] add a create table method that creates the correct table depending on database vendor. This makes the class self-documenting and standalone useable. 5. [x] add lifetime column to session table which allows to have different lifetimes for each session 6. [x] add isSessionExpired() method to be able to distinguish between a new session and one that expired due to inactivity, e.g. to display flash message to user 7. [x] added upgrade and changelog notes Commits ------- |

What is Symfony2?
Symfony2 is a PHP 5.3 full-stack web framework. It is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP.
Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
Requirements
Symfony2 is only supported on PHP 5.3.3 and up.
Be warned that PHP versions before 5.3.8 are known to be buggy and might not work for you:
-
before PHP 5.3.4, if you get "Notice: Trying to get property of non-object", you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=52083 and https://bugs.php.net/bug.php?id=50027);
-
before PHP 5.3.8, if you get an error involving annotations, you've hit a known PHP bug (see https://bugs.php.net/bug.php?id=55156).
-
PHP 5.3.16 has a major bug in the Reflection subsystem and is not suitable to run Symfony2 (https://bugs.php.net/bug.php?id=62715)
Installation
The best way to install Symfony2 is to download the Symfony Standard Edition available at http://symfony.com/download.
Documentation
The "Quick Tour" tutorial gives you a first feeling of the framework. If, like us, you think that Symfony2 can help speed up your development and take the quality of your work to the next level, read the official Symfony2 documentation.
