<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Suggestion: You can make this replacement operation atomic by either:
1) Allocating the container with the AO2_CONTAINER_ALLOC_OPT_DUPS_REPLACE flag. Note that this would require the container to be sorted.
2) Hold the lock on the file->metadata while performing the ao2_find() and ao2_link(). Pass the OBJ_NOLOCK flag to ao2_find() and ao2_link_options().</pre>

As long as an ast_bucket_file_retrieve() function exists, it's possible for multiple locations to share the same resource. This may not be the intended use, but it's possible.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">An underlying resource may be shared (ie: the same file on disk) but the ast_bucket_file object isn't. It is not an up to date real time representation of the file on-disk, it is a snapshot if you will at the time of retrieval.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Bucket is a generic file and directory API implemented as a thin wrapper over sorcery. It decouples the storage of files from the backend and provides the ability to set metadata on file themselves. What it means to have files in a "bucket" and details about the files themselves is left up to the user of the bucket API. It enforces no restrictions. Identification of things is done using URIs, which include a scheme. Modules implement specific schemes (local, for example) and take care of the implementation specific aspect of it. The ability to get bucket and file information in a JSON format is provided, as is the ability to copy and move files.
Stuff to focus on:
1. Is the API sane and complete?
2. Do the unit tests cover everything?
3. What do we want to do for URI parsing - I wrote a basic extremely optimistic one</pre>
