databases/p5-MLDBM-Serializer-JSON.
MLDBM::Serializer::JSON provides an extension to MLDBM to enable storing
the additional columns as JSON instead of Data::Dumper or FreezeThaw.
JSON is very widely used - from Perl over Ruby to Python and surely
JavaScript and so on.
Lib
* Removed tabs from various modules to make things work with python -tt.
* Quick fix to ldif.is_dn() to let multi-valued RDNs pass as valid.
Is too liberal in some corner-cases though...
* Fix to ldif.is_dn() to allow dashes in attribute type
* ldap.open() now outputs a deprecation warning
* module-wide locking is now limited to calling _ldap.initialize().
Still ldap.functions._ldap_function_call() is used to wrap all
calls for writing debug log.
Modules
* New LDAP options available in OpenLDAP 2.4.18+ supported in
LDAPObject.get/set_option():
ldap.OPT_X_KEEPALIVE_IDLE, ldap.OPT_X_KEEPALIVE_PROBES,
ldap.OPT_X_KEEPALIVE_INTERVAL,
ldap.OPT_X_TLS_CRLCHECK, ldap.OPT_X_TLS_CRLFILE
Doc
* Various small updates/improvements
* Fix the debugger invocation code to ensure it handles different combinations
of server version and libpq builds as cleanly as possible.
* Fix the double line number in the function properties dialog.
* Fix for log_statement in 7.4.

routines to define the boundary of the query region.
* The default page cache strives more diligently to avoid using memory beyond
what is allocated to it by SQLITE_CONFIG_PAGECACHE. Or if using page cache
is allocating from the heap, it strives to avoid going over the
sqlite3_soft_heap_limit64(), even if SQLITE_ENABLE_MEMORY_MANAGEMENT is not
set.

sqlite3_soft_heap_limit().

efficient query plan for each query.
* Enhanced the internal text-to-numeric conversion routines so that they work
with UTF8 or UTF16, thereby avoiding some UTF16-to-UTF8 text conversions.
* Fix a problem that was causing excess memory usage with large WAL
transactions in win32 systems.
* The interface between the VDBE and B-Tree layer is enhanced such that the
VDBE provides hints to the B-Tree layer letting the B-Tree layer know when it
is safe to use hashing instead of B-Trees for transient tables.
* Miscellaneous documentation enhancements.

Here is summary for security fixes:
* Security Fix: During evaluation of arguments to extreme-value
functions (such as LEAST() and GREATEST()), type errors did not
propagate properly, causing the server to crash. (Bug#55826)
* Security Fix: The server could crash after materializing a derived
table that required a temporary table for grouping. (Bug#55568)
* Security Fix: A user-variable assignment expression that is
evaluated in a logical expression context can be precalculated in a
temporary table for GROUP BY. However, when the expression value is
used after creation of the temporary table, it was re-evaluated, not
read from the table and a server crash resulted. (Bug#55564)
* Security Fix: Pre-evaluation of LIKE predicates during view
preparation could cause a server crash. (Bug#54568)
* Security Fix: GROUP_CONCAT() and WITH ROLLUP together could cause a
server crash. (Bug#54476)
* Security Fix: Queries could cause a server crash if the GREATEST()
or LEAST() function had a mixed list of numeric and LONGBLOB
arguments, and the result of such a function was processed using an
intermediate temporary table. (Bug#54461)
* Security Fix: Queries with nested joins could cause an infinite loop
in the server when used from stored procedures and prepared
statements. (Bug#53544)
* Security Fix: The PolyFromWKB() function could crash the server when
improper WKB data was passed to the function. (Bug#51875)
Upstream changes:
2.0004 Sep 12 18:38:00 2010 PDT
- t/27_filehandle.t has been fixed to work with Test::More 2.
2.0003 Sep 12 12:02:00 2010 PDT
- t/43_transaction_maximum.t has been fixed. It was broken in the
previous release for systems that will only open so many files.
2.0002 Sep 5 12:35:00 2010 PDT
- Error messages from DBM::Deep now use the caller???s file name.
They used incorrectly to use the name of the program ($0).
- begin_work now checks correctly to see whether the new transac-
tion exceeds the number the file was created to support. Some-
times it would allow a few more transactions, and then proceed
to corrupt the database (RT#60903).
- The description of the file header in DBM::Deep::Internals has
been brought up to date.
