hamsterdb 1.1.3 - Release Notes

This release improves performance and adds a new feature: records can now read and written partially (with flag HAM_PARTIAL). This feature required changes to the ham_record_t structure, therefore the ABI of hamsterdb is not backwards compatible (but the API and file format is). The libtool version was incremented, and the Win32 libraries now have the version encoded in the filename of the dynamic and static libraries.

New Features

Implemented partial read/write - records can now be read or written partially (see flag HAM_PARTIAL for ham_find, ham_insert and others) This new feature caused a change to ham_record_t, thus making the ABI of hamsterdb incompatible to older versions. This feature is test-covered by nearly 900 unittests.
Added a new function to get the Environment handle of a Database (ham_get_env)

Bugfixes

Bugfix - fixed an invalid read of 3 bytes in the freelist
Bugfix - ham_get_parameter failed if database was opened read-only (thanks, Austin)
Bugfix - if a cachesize was specified then it was not propagated correctly and ignored; this bugfix caused serious performance improvements compared to 1.1.2!

Other Changes

Windows library and dll are now renamed to libhamsterdb-.lib and hamsterdb-.dll
Ongoing refactoring and code improvements

Known Issues
