Proxy backend that mirrors writes to several internal backends.
This class defines a multi-write backend. Multiple backends can be registered to this proxy backend and it will act as a single backend. Use this when all access to those backends is through this proxy backend. At least one of the backends must be declared the "master" backend.
Only use this class when transitioning from one storage system to another.
Read operations are only done on the 'master' backend for consistency. Write operations are performed on all backends, starting with the master. This makes a best-effort to have transactional semantics, but since requests may sometimes fail, the use of "autoResync" or background scripts to fix inconsistencies is important.

FileBackendMultiWrite::__construct | ( | array | $config | ) |

FileBackendMultiWrite::concatenate | ( | array | $params | ) |
Concatenate a list of storage files into a single file system file.
The target path should refer to a file that is already locked or otherwise safe from modification from other processes. Normally, the file will be a new temp file, which should be adequate.

FileBackendMultiWrite::directoryExists | ( | array | $params | ) |
Check if a directory exists at a given storage path.
For backends using key/value stores, a directory is said to exist whenever there exist any files with paths using the given directory path as a prefix followed by a forward slash. For example, if there is a file called "mwstore://backend/container/dir/path.svg" then directories are said to exist at "mwstore://backend/container" and "mwstore://backend/container/dir". These can be thought of as "virtual" directories.
Backends that directly use a filesystem layer might enumerate empty directories. The clean() method should always be used when files are deleted or moved if this is a concern. This is a trade-off to avoid write amplication/contention on file changes or read amplification when calling this method.
Storage backends with eventual consistency might return stale data.

FileBackendMultiWrite::fileExists | ( | array | $params | ) |
Check if a file exists at a storage path in the backend.
This returns false if only a directory exists at the path.
Callers that only care if a file is readily accessible can use non-strict comparisons on the result. If "does not exist" and "existence is unknown" must be distinguished, then strict comparisons to true/null should be used.

FileBackendMultiWrite::getDirectoryList | ( | array | $params | ) |
Get an iterator to list all directories under a storage directory.
If the directory is of the form "mwstore://backend/container", then all directories in the container will be listed. If the directory is of form "mwstore://backend/container/dir", then all directories directly under that directory will be listed. Results will be storage directories relative to the given directory.
Storage backends with eventual consistency might return stale data.
Failures during iteration can result in FileBackendError exceptions (since 1.22).

FileBackendMultiWrite::getFileHttpUrl | ( | array | $params | ) |
Return an HTTP URL to a given file that requires no authentication to use.
The URL may be pre-authenticated (via some token in the URL) and temporary. This will return null if the backend cannot make an HTTP URL for the file.
This is useful for key/value stores when using scripts that seek around large files and those scripts (and the backend) support HTTP Range headers. Otherwise, one would need to use getLocalReference(), which involves loading the entire file on to local disk.

FileBackendMultiWrite::getScopedLocksForOps | ( | array | $ops, |
StatusValue | $status ) |
Get an array of scoped locks needed for a batch of file operations.
Normally, FileBackend::doOperations() handles locking, unless the 'nonLocking' param is passed in. This function is useful if you want the files to be locked for a broader scope than just when the files are changing. For example, if you need to update DB metadata, you may want to keep the files locked until finished.
