Cache component extracted from the Doctrine Common project. Documentation

This library is deprecated and will no longer receive bug fixes from the Doctrine Project. Please use a different cache library, preferably PSR-6 or PSR-16 instead.

  • File cache names are too long. Checks limiting it to 255 do not actually work properly in all cases.

    File cache names are too long. Checks limiting it to 255 do not actually work properly in all cases.

    First of all, there was this issue posted for Symfony here: https://github.com/symfony/symfony/issues/19363 . I encountered the same thing and spent a lot of time investigating it and came up to this: When using FileCache filenames sometimes are longer, than supported. I am using docker containers on vagrant with VBox linked shared folders. There is a limit for a FILE_NAME of 255 characters. I tried renaming some of the long filenames inside cache directories and the error switched to another folder: /var/www/html/var/cache/de~/annotations/fd -> var/www/html/var/cache/de~/annotations/44 for example. So it looks like command is able to process the first folder, but then fails on the second one, as there is also a very long filename (256 characters including extension, which should be 255).

    I am using docker containers on vagrant with VirtualBox and I suspect that the vboxsf might have some FILE_NAME or PATH_NAME limitations and those are 255 and 4096 respectively.

    Then I tried to reduce filenames from 256 chars and went to Doctrine\Common\Cache\FilesystemCache and changed extension from .doctrinecache.data to .doctrine.data and everything worked, I was able to clear the cache after clearing the previous one manually (it still had long files).

    It led me to suspect, that the problem lies within Doctrine\Common\Cache\FileCache, getFilename() does not work properly and sometimes has wrong behaviour. I think this issue is also connected to #174 .

    IMPORTANT: Issue persists only for Symfony dev environment and works fine for prod.

  • FilesystemCache should not use that many directories

    FilesystemCache should not use that many directories

    ... in order to have a manageable amount of items per directory. See this blog post.

    When splitting the hash into four pieces, each containing 16 chars, with each 16 possible values this can lead to 16^16 (1.84467441e19) folders at each level. This might lead to an amount which goes far beyond filesystem limits. Even if a filesystem could handle that many items/folders, "stat operations such as listing files, following paths, or checking for the existence of a file" will be super slow!

  • Reduced number of subdirectories generated by FileCache

    Reduced number of subdirectories generated by FileCache

    Currently FileCache implementation generates 32 subdirectories for each cache entry. This is inefficient (FS), useless (every single file is going to be stored in its own subdirectory) and leads to quite hard to debug/detect bugs caused by max filepath length (260 chars on Windows).

  • Drop RiakCache support

    Drop RiakCache support

    Breaking change, but as per #323 this seems a reasonable way forward if released as a semver breaking change?

    The code isn't valid on PHP 7.2+, which is supported, meaning that PHP 7.1 is the only version of PHP that is supported upstream that would work with the code

    It's pretty evident on the various forks that have been made, no one really seems that interested in maintaining the support properly

  • fix file cache naming under windows surpassing MAX_PATH

    fix file cache naming under windows surpassing MAX_PATH

    I realised that doctrine annotation cache (which uses long cache keys) is failing in symfony under windows. Its because in Windows the whole path is limited to 260 chars. See http://stackoverflow.com/questions/1880321/why-does-the-260-character-path-length-limit-exist-in-windows

    Also fixed travis tests with apcu due to new releases of apcu for php 5 and 7.

  • 1.12.1 and PHP7 breaking compatibility

    1.12.1 and PHP7 breaking compatibility

    Hi,

    I just noticed something strange. Based on https://github.com/doctrine/cache/blob/1.12.1/composer.json, it seems that 1.12.1 should be ~7.1 and 8.0 compatible. But in this version, we can also see this: https://github.com/doctrine/cache/blob/1.12.1/lib/Doctrine/Common/Cache/Psr6/TypedCacheItem.php#L24

        public function __construct(
        private string $key,
        private mixed $value,
        private bool $isHit,
    ) {
    }

    But if I'm right, and based on PHP website, this is a PHP8 feature.

    Can you please confirm that 1.12.* is not PHP7 compatible please?

    Thank you.

  • PSR-6 implementation

    PSR-6 implementation

  • Sunsetting doctrine/cache

    Sunsetting doctrine/cache

    Hello,

    with many great PSR-6 and PSR-16 implementations available, it is no longer feasible for the Doctrine Project to keep maintaining a separate cache library. We have thus decided to sunset doctrine/cache and prepare its removal process. As many libraries, including our own, depend on this package, this process will be gradual.

    Version 1.11 will deprecate all classes and interfaces provided, but the library will continue working as expected. We will provide the same level of support as we have so far. We will also release version 2.0, which will drop all cache implementations and only retain the abstract CacheProvider class as well as the interfaces. 2.0 is designed as a lightweight package that compatibility libraries (e.g. symfony/cache which provides a bridge to PSR interfaces) can depend on.

    If your package currently depends on any doctrine/cache version, here's what you should do:

    • if your package uses any cache implementation, you should find a suitable alternative and replace usages.
    • if your package doesn't use any cache implementations but needs the interfaces, you should amend the current version constraint to allow installing doctrine/cache 2.0, e.g. "doctrine/cache": "^1.10 || ^2.0"
    • if your package doesn't use any classes from doctrine/cache at all, drop the package requirement from composer.json.

    If you would like to take over maintenance of the package, please reach out to us.

    As of PHP 7.2 object is a reserved word. Therefore, this line: https://github.com/doctrine/cache/blob/master/lib/Doctrine/Common/Cache/RiakCache.php#L8 triggers a PHP error in 7.2. This PR attempts to solve this issue by aliasing the import.

    the packagist information for doctrine/cache still looks like all is fine: https://packagist.org/packages/doctrine/cache

    i suggest to change the description to explain the status, and also mark the package as abandoned so that composer install spits out a warning that users should move on to something else.
