README for Package CL-STORE. Author: Sean Ross Homepage: http://www.common-lisp.net/project/cl-store/ Version: 0.8.11 0. About. CL-STORE is an portable serialization package which should give you the ability to store all common-lisp data types (well not all yet) into streams. See the cl-store manual (docs/cl-store.texi) for more in depth information. !!! NOTE: The cl-store-xml backend is deprecated. 1. Usage The main entry points are - [Method] cl-store:store (obj place &optional (backend *default-backend*)) => obj Where place is a path designator or stream and backend is one of the registered backends. - [Method] cl-store:restore (place &optional (backend *default-backend*)) => restored-objects Where place and backend is as above. - cl-store:restore is setfable, which I think makes for a great serialized hit counter. eg. (incf (restore place)) NOTE. All errors signalled within store and restore can be handled by catching store-error and restore-error respectively. 2. Optimizing. While cl-store is generally quickish it still has a tendency to do a lot of consing. Thanks to profilers this has been pinned down to the rehashing of the hash-tables which track object circularities. From 0.4.0 cl-store has three new variables *store-hash-size*, *restore-hash-size* and *check-for-circs*, proper usage of these new variables can greatly reduce the consing (and time taken) when storing and restoring large objects. - *store-hash-size* and *restore-hash-size At the beginning of storing and restoring an eq hash-table is created with a default size of 50 to track objects which have been (re)stored. On large objects however the rehashing of these hash-tables imposes a severe drain on performance. By binding these two variables to appropriately large values about (100010 for a hash-table with 100000 int->string mappings) you can obtain a decent performance improvement. This may require a bit of fiddling to find the best tradeoff between rehashing and creating a large hash-table. - *check-for-circs* Binding this variable to nil when storing or restoring an object inhibits all checks for circularities which gives a severe boost to performance. The downside of this is that no restored objects will be eq and attempting to store circular objects will hang. The speed improvements are definitely worth it if you know that there will be no circularities or shared references in your data (eg spam-filter hash-tables). Enjoy Sean.
