LinearStore issues:
Store:
------
1. (FIXED) Overwrite identity: When recovering a previously used file, if the write boundary coincides with old record
start, no way of discriminating old from new at boundary (used to use OWI).
2. (FIXED) QPID-5357: Recycling files while in use not working, however, files are recovered to EFP during recovery. Must solve
#1 first.
3. (FIXED) QPID-5358: Checksum not implemented in record tail, not checked during read.
4. QPID-5359: Rework qpid management parameters and controls (QMF).
5. QPID-5360: Consistent logging: rework logging to provide uniform and consistent logging from store (both logging
level and places where logging occurs).
6. QPID-5361: No tests
* No existing tests for linearstore:
** Basic broker-level tests for txn and non-txn recovery
** Store-level tests which check write boundary conditions
** Unit tests
** Basic performance tests
7: QPID-5362: No tools
* Store analysis and status
* Recovery/reading of message content
8. One journal file lost when queue deleted. All files except for one are recycled back to the EFP.
9. Complete exceptions - several exceptions thrown using jexception have no exception numbers
Current bugs and performance issues:
------------------------------------
1. BZ 1035843 - Slow performance for producers
2. (FIXED) QPID-5387 (BZ 1036071) - Crash when deleting queue
3. (FIXED) QPID-5388 (BZ 1035802) - Segmentation fault when recovering empty queue
4. (UNABLE TO REPRODUCE) BZ 1036026 - Unable to create durable queue - framing error - possibly caused by running both stores at the same time
5. (UNABLE TO REPRODUCE) BZ 1038599 - Abort when deleting used queue after restart - may be dup of QPID-5387 (BZ 1036071)
6. BZ 1039522 - Crash during recovery - JournalFile::getFqFileName() -JERR_JREC_BADRECTAIL
7. BZ 1039525 - Crash during recovery - journal::jexception - JERR_JREC_BADRECTAIL
8. (FIXED) QPID-5442 (BZ 1039949) - DTX test failure - missing XIDs
9. (FIXED) QPID-5460 (BZ 1051097) - Transactional messages lost during recovery
10. QPID-5464 - Incompletely created journal files accumulate in EFP
11. QPID-5473 (BZ 1051924) - Recovery where last record in file is truncated (ie spans files), but following file is uninitialized causes crash
Code tidy-up
------------
* Remove old comments
* Use c++ cast templates instead of (xxx)y
* Member names: xxx_
* Rename classes, functions and variables to camel-case
* Add Doxygen docs to classes
