MIPS and x86_64. [#11575]</li>

system holds mutex resources that must be freed when the mutex is

of the database environments databases. [#12039]</li>

<li>Threads of control joining database environments are now configured
|
|||
|
|
for all of the subsystems (lock, log, cache, or transaction) for which
|
|||
|
|
the environment was originally configured, it is now an error to attempt

configuration of additional subsystems after an environment is created.

non-logging updated pages. [#12763]</li>

<li>Fix a bug that could cause an unreported deadlock if the application

duplicate record. [#12893]</li>

<div class="orderedlist">

<ol type="1">
|

|
|
<li>Binding performance has been improved by using System.arraycopy in
|
|||
|
|
the FastOutputStream and FastInputStream utility classes. [#12002]</li>
|
|||
|
|
<li>The objectToEntry method is now implemented in all TupleBinding
|
|||
|
|
subclasses (IntegerBinding, etc) so that tuple bindings are fully
|
|||
|
|
nestable. An example of this usage is a custom binding that dynamically
|
|||
|
|
discovers the data types of each of the properties of a Java bean class.
|
|||
|
|
For each property, it calls TupleBinding.getPrimitiveBinding using the
|
|||
|
|
property's type (class). When the custom binding's objectToEntry method
|
|||
|
|
is called, it in turn calls the objectToEntry method of the nested
|
|||
|
|
bindings for each property. [#12124]</li>
|
|||
|
|
<li>The getCause method for IOExceptionWrapper and
|
|||
|
|
RuntimeExceptionWrapper is now defined so that nested exceptions appear
|
|||
|
|
in stack traces for exceptions thrown by the collections API. [#11992]</li>
|
|||
|
|
<li>TupleBinding.getPrimitiveBinding can now be passed a primitive type
|
|||
|
|
class as well as a primitive wrapper class. The return value for
|
|||
|
|
Integer.TYPE and Integer.class, for example, will be the same binding.
|
|||
|
|
[#12035]</li>
|
|||
|
|
<li>Improvements have been made to prevent the buffer used in serial and
|
|||
|
|
tuple bindings from growing inefficiently, and to provide more
|
|||
|
|
alternatives for the application to specify the desired size. For
|
|||
|
|
details see com.sleepycat.bind.serial.SerialBase and
|
|||
|
|
com.sleepycat.bind.tuple.TupleBase. [#12398]</li>
|
|||
|
|
<li>Add StoredContainer.getCursorConfig, deprecate isDirtyRead.
|
|||
|
|
Deprecate StoredCollections.dirtyReadMap (dirtyReadSet, etc) which is
|
|||
|
|
replaced by configuredMap (configuredSet, etc). Deprecated
|
|||
|
|
StoredContainer.isDirtyReadAllowed with no replacement (please use
|
|||
|
|
DatabaseConfig.getDirtyRead). Also note that
|
|||
|
|
StoredCollections.configuredMap (configuredSet, etc) can be used to
|
|||
|
|
configure read committed and write lock containers, as well as read
|
|||
|
|
uncommitted containers, since all CursorConfig properties are supported.
|
|||
|
|
[#11776]</li>
|
|||
|
|
<li>Add the protected method SerialBinding.getClassLoader so that
|
|||
|
|
subclasses may return a specific or dynamically determined class loader.
|
|||
|
|
Useful for applications which use multiple class loaders, including
|
|||
|
|
applications that serialize Groovy-defined classes. [#12764] [#12749]</li>

<li>Add new DbTxn class methods allowing applications to set/get a
|
|||
|
|
descriptive name associated with a transaction. The descriptive name
|
|||
|
|
is also displayed by the db_stat utility. [#0382]</li>
|
|||
|
|
<li>Fix a bug where aborting a transaction with a large number of nested
|
|||
|
|
transactions could take a long time. [#10972]</li>
|
|||
|
|
<li>Add support to allow the TXN_WRITE_NOSYNC flag to be specified on
|
|||
|
|
the transaction handle. [#11151]</li>
|
|||
|
|
<li>Fix a bug that could cause a page to be on the free list twice if
|
|||
|
|
it was originally put on the free list by a non-transactional update and
|
|||
|
|
then reallocated in a transaction that aborts. [#11159]</li>
|
|||
|
|
<li>Remove the requirement for the DB_AUTO_COMMIT flag to make database
|
|||
|
|
operations transactional. Specifying the database environment as
|
|||
|
|
transactional or opening the database handle transactionally is
|
|||
|
|
sufficient. [#11302]</li>
|
|||
|
|
<li>Fix a bug so that environments created from errant programs that
|
|||
|
|
called dbp->close while transactions were still active can now be
|
|||
|
|
recovered. [#11384]</li>
|
|||
|
|
<li>Fix a bug that caused free pages at the end of a file to be
|
|||
|
|
truncated during recovery rather than placed on the free page list.
|
|||
|
|
[#11643]</li>
|
|||
|
|
<li>Fix a bug that caused a page to have the wrong type if the truncate
|
|||
|
|
of a BREE or RECNO database needed to be rolled forward. [#11670]</li>
|
|||
|
|
<li>Fix a bug when manually undoing a subdb create, dont try to free a
|
|||
|
|
root page that has not been allocated. [#11925]</li>
|
|||
|
|
<li>Add a check on database open to see if log files were incorrectly
|
|||
|
|
removed by system administration mistakes. [#12178]</li>
|
|||
|
|
<li>Fix a bug when calling DB->pget and then specifying the
|
|||
|
|
DB_READ_COMMITTED (DB_DEGREE_2) on a cursor. If followed by a
|
|||
|
|
DBC->c_pget, the primary database would incorrectly remain locked.
|
|||
|
|
[#12410]</li>
|
|||
|
|
<li>Fix a bug where the abort of a transaction in which a sub database
|
|||
|
|
was opened with the DB_TXN_NOT_DURABLE flag could fail. [#12420]</li>
|
|||
|
|
<li>Fix a bug that could cause an abort transaction that allocated new
|
|||
|
|
pages to a file that were not flushed to disk prior to the abort
|
|||
|
|
transaction to report out of disk space. [#12743]</li>
|
|||
|
|
<li>Fix a bug that could prevent multiple creates and destroys of the
|
|||
|
|
same file to be recovered correctly. [#13026]</li>
|
|||
|
|
<li>Fix a bug when recovery previously handled a section of the log that
|
|||
|
|
did not contain any transactions. [#13139]</li>
|
|||
|
|
<li>Fix a bug that could result in the loss of durability in
|
|||
|
|
Transactional Environments on Mac OS X. [#13149]</li>
|
|||
|
|
<li>Fix a bug that could cause the improper reuse of a transaction id
|
|||
|
|
when recovery restores prepared transactions. [#13256]</li>
