More-or-less working version of CHT. Needs a lot of performance/stability/code cleanup work.

CHT is starting to work.

libdfa ported to new hash table implementation. (Uses nested top actions.)

- linkedListNTA is now re-entrant.
...
- linearHashNTA now uses nested top actions, is re-entrant, and supports a
non-re-entrant iterator
- 'recursive' nested top actions allow nested top actions to be nested within each
other.

The linked list implementation now uses nested top actions. (Also, many bugfixes regarding nested top actions were introduced.)

Working, non-concurrent linear hash and linked list implementations.
...
The idea is to implement the non-concurrent versions, and then convert
them to concurrent versions using nested top actions.

Starting to rip the old jbhash implementation out, and replace it with a
...
linear hash implementation. In particular, I've implemented (sort of) an
iterator for linear hash, and (sort of) ported libdfa to linearhash.c
I say 'sort of' since this functionality is broken with this commit. On the other hand, CVS should build now, and the tests under lladd will pass. libdfa's new tests don't pass at the moment.

Partially implemented config file parser. Validates, but does not populate NetworkSetup object yet.

Some changes to pobj.c to support operations for non-persistent (transient)

objects. Enhancement to test-list program to work with transient objects
as well. Minor fix to header file (typo).

Switched to growable (unlimited) persistent objects / static references
...
repositories. Has been tested with 15K objects and appears to work. Also
done some significant chnages to auxiliary modules in libpobj, and the
trivial test program (test-list).

Small change to library list order (pobj depends on lladd).
2004-12-14 01:39:12 +00:00

Gilad Arnold
fc42d83efc
Added pobj library sources, header file, and test programs. Small changes were
...
made to src/Makefile.am in order to include src/pobj build, but no corresponding
change was made to test/Makefile.am (will be done in the near future).

Lots of optimizations; re-did on-disk layout for the linear hash table.

Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.)
2004-10-18 18:24:54 +00:00

a078f25475
Implemented a linear hash from scratch. Concurrency hasn't been done, but it's probably correct in the single thread case.
2004-10-12 02:44:47 +00:00
Sears Russell
5064e3fac2
Implemented pages that store fixed sized records efficiently, and a java-style ArrayList data structure that efficiently supports (relatively) clustered, O(1) access time expandable arrays. (This will be used for the hash implementation...)
2004-10-06 06:08:09 +00:00
Sears Russell
9268b1d9cf
Added support for gcov, and ran gprof. Shaved 10% off the runtime of check_page by optimizing rw.c
2004-10-04 05:24:12 +00:00
Sears Russell
96e7af92a4
Added test cases for Tprepare(), implemented some redo-only operations, and started to clean up record allocation/deallocation.
...
Also, numerous bugfixes.
2004-10-02 07:29:34 +00:00
Sears Russell
811bc5c710
Implemented a freespace manager that should safely allocate space, even in the face of crashes, and can reclaim unused space (unless an application opens more than one simultaneous transaction that performs allocations)
...
Fixed some blob bugs (by adding extra fdatasync() calls).
Began factoring out the page management code so that it is an extenstion, and a less integral part of lladd.
2004-08-21 00:03:30 +00:00

Fixed regressions, major update of page / slotted interfaces in anticipation of moving LLADD towards a generic transactional page system.
2004-08-17 01:46:17 +00:00

Added (untested) support for whole-page operations, lladdhash now works.

Fixed data corruption bug in the freelist implementation, and corrected lsn updates.
2004-07-30 02:07:41 +00:00
Sears Russell
961b63af15
Rewrote / refactored page.h. Now, it uses a freelist to reclaim slotid's within a page, and is implemented as two seperate modules. The first handles lsn's, and (will soon) check the type of each page, and then delegate work to a particular implementation of the second module.
2004-07-30 01:28:39 +00:00

O_DIRECT (sort of...)
2004-07-27 21:30:54 +00:00
Sears Russell
54ba9b0347
Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy.
...
Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.
2004-07-27 01:04:35 +00:00
