4 * The 'DB' format has been removed; users should use 'DB1' instead
6 * Internals of 'DB1' format have changed so that it should be a bit
7 more reliable but perhaps a little slower
9 * The 'dbDisconnect' generic has been removed since it is no longer
10 necessary for the 'DB1' format (as it was before). It was never
11 needed for the 'RDS' format and one never existed for that format.
17 * For 'filehashRDS' class, the 'dbDir' slot has been renamed to 'dir'.
19 * An attempt has been made to normalize the error handling to make it
22 * The various 'dump' functions have been given a 'type' argument
28 * Added function dbLazyLoad for lazy loading filehash databases.
30 * dbCreate and dbInit are now generics with a method for character
31 vectors. The behavior should be the same as before, by default.
35 * The second argument to dbMultiFetch is 'key', not 'keys'.
37 * dbInitialize is deprecated
39 * 'DB1' and 'RDS' formats use normalizePath() for resolving paths to
42 * There is a vignette now [via vignette("filehash")]
48 * Added methods for "[[", "$", "[[<-", and "$<-" for filehash
49 objects. Only character indices are allowed
51 * filehash-DB functions use the new serialize() from R 2.4.0 so that
52 numeric data will not suffer from rounding error due to previous use
53 of serialize(ascii = TRUE).
55 * New format filehash-DB1 which stores the key index/map and data in a
58 * New "filehash" method for lapply so that functions can be applied to
65 * Patch release, changed some internals for the "DB" type databases
67 * Added test database for regression testing in future releases
73 * Added name mangling scheme to prevent clobbering on case-insensitive
74 OSes like Windows (thanks to Bill Venables and David Brahm)
76 * Added dumpImage, dumpObjects, dumpDF functions for dumping various
77 things to filehash databases
79 * Added filehashOption() function for setting global options; right
80 now only the default database type can be set
82 * dbLoad and db2env are regular functions now rather than
83 generics/methods. dbLoad's default 'env' is the parent frame now
85 * Added a "filehash" method for 'with'
87 * Added new generic dbUnlink which deletes a database from the disk
