[Code reviewed by Love Hörnquist Åstrand <lha@kth.se>] Added heim_db_*() entry points for dealing with databases, and make krb5_aname_to_localname() use it. The following enhancements to libheimbase are included: - Add heim_data_t and heim_string_t "reference" variants to avoid memory copies of potentially large data/strings. See heim_data_ref_create() and heim_string_ref_create(). - Added enhancements to heim_array_t to allow their use for queues and stacks, and to improve performance. See heim_array_insert_value(). - Added XPath-like accessors for heim_object_t. See heim_path_get(), heim_path_copy(), heim_path_create(), and heim_path_delete(). These are used extensively in the DB framework's generic composition of ACID support and in the test_base program - Made libheimbase more consistent with Core Foundation naming conventions. See heim_{dict, array}_{get, copy}_value() and heim_path_{get, copy}(). - Added functionality to and fixed bugs in base/json.c: - heim_serialize(); - depth limit for JSON parsing (for DoS protection); - pretty-printing; - JSON compliance (see below); - flag options for parsing and serializing; these are needed because of impedance mismatches between heim_object_t and JSON (e.g., heim_dict_t allows non-string keys, but JSON does not; heimbase supports binary data, while JSON does not). - Added heim_error_enomem(). - Enhanced the test_base program to test new functionality and to use heim_path*() to better test JSON encoding. This includes some fuzz testing of JSON parsing, and running the test under valgrind. - Started to add doxygen documentation for libheimbase (but doc build for libheimbase is still incomplete). Note that there's still some incomplete JSON support: - JSON string quoting is not fully implemented; - libheimbase lacks support for real numbers, while JSON has it -- otherwise libheimbase is a superset of JSON, specifically in that any heim_object_t can be a key for an associative array. The following DB backends are supported natively: - "sorted-text", a binary search of sorted (in C locale), flat text files; - "json", a backend that stores DB contents serialized as JSON (this is intended for configuration-like contents). The DB framework supports: - multiple key/value tables per-DB - ACID transactions The DB framework also natively implements ACID transactions for any DB backends that a) do not provide transactions natively, b) do provide lock/unlock/sync methods (even on Windows). This includes autocommit of DB updates outside transactions. Future DB enhancements may include: - add backends for various DB types (BDB, CDB, MDB, ...); - make libhdb use heim_db_t; - add a command-line tool for interfacing to databases via libheimbase (e.g., to get/set/delete values, create/copy/ backup DBs, inspect history, check integrity); - framework-level transaction logging (with redo and undo logging), for generic incremental replication; - framework-level DB integrity checking. We could store a MAC of the XOR of a hash function applied to {key, value} for every entry in the DB, then use this to check DB integrity incrementally during incremental replication, as well as for the whole DB.
