如何修复“ touch（）：Utime失败：不允许操作”用symfony保存缓存？ [英] How to fix "touch(): Utime failed: Operation not permitted" on saving cache with symfony?

问题描述

我想用symfony\cache缓存一些响应。但是我的缓存和symfony默认缓存有时会出错。

I want to caching some response with symfony\cache. But I've got some error with my cache and sometime with the symfony default cache.

配置：

Debian 9在vagrant上（通过vagrant的bindfs链接到源代码目录）
和Apache2

php 7.2 / symfony 4.1

apcu已启用

Debian 9 on vagrant (with vagrant bindfs link to source code directory) with Apache2
php 7.2 / symfony 4.1
apcu enabled

要缓存我的响应，我使用FilesystemAdapter和dir {projectDir} / var / cache / {env} / api-cache和命名空间app.cache

For caching my response I use the FilesystemAdapter with dir {projectDir}/var/cache/{env}/api-cache and namespace app.cache

登录默认的symfony代码：

Log for default symfony code :

 cache.WARNING: Failed to save key "%5B%5BC%5DApp%5CEntity%5CReport%5CReportItem%24hasBeenPushed%5D%5B1%5D" (integer) {"key":"%5B%5BC%5DApp%5CEntity%5CReport%5CReportItem%24hasBeenPushed%5D%5B1%5D","type":"integer","exception":"[object] (ErrorException(code: 0): touch(): Utime failed: Operation not permitted at /vagrant-bindfs/vendor/symfony/cache/Traits/FilesystemCommonTrait.php:90)"} []

带有我的代码的日志：

php.DEBUG: User Warning: Failed to save key "my_tag" (string) {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\SilencedErrorContext: {\"severity\":512,\"file\":\"/vagrant-bindfs/vendor/symfony/cache/CacheItem.php\",\"line\":184,\"trace\":[{\"file\":\"/vagrant-bindfs/vendor/symfony/cache/Adapter/AbstractAdapter.php\",\"line\":242,\"function\":\"log\",\"class\":\"Symfony\\\\Component\\\\Cache\\\\CacheItem\",\"type\":\"::\"}],\"count\":1})"} []
app.ERROR: Cache not save : my_tag [] []

何时我在Symfony\组件\缓存\适配器\AbstractAdapter-> commit（）中记录了有关该异常的一些信息：
ErrorException
touch（）：Utime失败：不允许操作

When I log some information about the exception in Symfony\Component\Cache\Adapter\AbstractAdapter->commit() I got this : ErrorException touch(): Utime failed: Operation not permitted

我已经搜索了解决方案，但没有任何效果。
我认为这是缓存目录上的问题，也许是vagrant和vagrant-binfs的问题，但我不明白。

I already search a solution but nothing works. I think it's a problem of right on the cache directories and maybe a problem with vagrant and vagrant-binfs but I do not understand it.

我该怎么办？做/检查解决这个问题？

What can I do/check to solve this ?

推荐答案

如果您碰巧使用FAT / FAT32或时间戳范围受到严格限制的其他文件系统，

If you happened to use FAT/FAT32 or another file system with severely limited timestamp range, then that warning is to be expected.

Symfony的 FilesystemCommonTrait :: write（）方法调用 touch（）函数（unix时间戳为0）强制过期缓存的内容。 Unix时间戳0代表1970-01-01日期。根据Wikipedia，在FAT文件系统中，允许的时间戳范围是1980-01-01至2099-12-31。因此， touch（）函数失败并发出警告。

Symfony's FilesystemCommonTrait::write() method calls touch() function with unix timestamp 0 to force expire cached content. Unix timestamp 0 represents 1970-01-01 date. In FAT file system the allowed timestamp range is 1980-01-01 to 2099-12-31, according Wikipedia. So the touch() function fails and a warning is issued.

解决方法是修改 FilesystemCommonTrait :: write（）方法，在第80行附近。

The workaround is to modify the FilesystemCommonTrait::write() method, around line 80.

查找行：

if (null !== $expiresAt) {
    touch($this->tmp, $expiresAt);
}

在这些行之前插入：

if (0 === $expiresAt) {
    $expiresAt = time() - 1;
}

这应该通过立即使缓存的内容过期而获得几乎相同的结果，但是没有使用无效的文件系统时间戳记。

This should achieve virtually the same result by instantly expiring the cached content, but without using an invalid file system timestamp.

或者，更改文件系统类型。

Alternatively, change the file system type.
