upscaledb - embedded database technology: Release of upscaledb 2.1.13

Posted on Feb 07, 15:26:51 CET 2016

From the release notes:

This release fixes a few bugs. This is the last stable release before 2.2.0.

The most significant fixes are:

#47: fixed bad assert in ups_cursor_move; this caused crashes in debug mode
#66: return with error if a database is modified by a committed transaction which was not yet flushed to disk; this caused crashes when closing an Environment (ups_env_close)
#64: fixed segfault when recovering a database with a custom compare function; deprecated ups_db_set_compare_func, use ups_register_compare/UPS_PARAM_CUSTOM_COMPARE_NAME instead. Also, the .NET/C# delegate for custom compare functions has been changed, the delegate has to perform the marshalling now (see unittests for a sample)
issue #60: files are now truncated after a database was deleted with ups_env_erase_db

The file format is not compatible to 2.1.12.

CALL FOR ACTION:
Are you using the "partial reads/writes"? i.e. searching or inserting partial records with UPS_PARTIAL? If yes then please tell me - I still remove functionality that is not used or rarely used.

All files are available on the download page.

Forget it.
I had downloaded the package from the upscaledb.com and I got the compilation error .
Now, I have cloned the github project and it compiled fine.

Yes, there has been a minor change in the database header structure due to a bug fix.

Is the above correct "The file format is not compatible to 2.1.12."?
