* fuse/md-cache: add support for the 'fopen-keep-cache' mount optionBrian Foster2012-07-131-7/+25
| | | | | | | | | | | | | | | | | | | | | | fopen-keep-cache disables unconditional page-cache invalidations on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that behavior with detection of remote changes and explicit invalidations from mount/fuse. This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).

* quick-read, md-cache: selectively cache xattr data to conserve memoryBrian Foster2012-05-081-6/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The md-cache translator can cache items for a long period of time and thus is sensitive to memory usage associated with the items it references. This implements two changes to help conserve memory: - quick-read - Migrate the file content data to a local dict and delete from the xdata dict that passes through the stack. - md-cache - Create a local dict to selectively store the xattr data md-cache is interested in. This includes a slight optimization to not allocate an empty dict in the case where we have not received any xattr's of interest. I've tested both changes independently and together by running a readdirp test against several compiled source trees (~340k files). The base test results in a 7.7GB RSS on the client. The quick-read modification cuts RSS down to 4.1GB, which is still large due to md-cache unintelligently caching a large number of empty dictionaries. The combined modification cuts RSS down to 462MB on the same workload. NOTE: Theoretically the md-cache change should supercede the quick-read change, but practically I save an extra 150MB or so with both. I already had the change and consider it an improvement that quick-read clean up after itself.

| | | | | | | | | | | | | | | | We currently either dict_ref() or dict_copy() into mdc->xattr. The double dict_ref() call path is obvious. Alternatively, dict_copy() does not ref the dict in the situation where it creates a new dict, but we only call dict_copy() in this context when we already have a dict, which should mean the extra ref is unnecessary.

Fix the condition to support the no caching scenario. A longer term approach is to use gettimeofday() for more accurate granularity, but this apparently fixes a known bug.
