Add lsmusr.wiki. User documentation for lsm. check-in: c50bcdc37d user: dan tags: trunk

Fix block pointer related bug introduced by the previous commit. check-in: 579ee866b7 user: dan tags: trunk
11:23
Change the format of uncompressed databases so that the prev/next pointers at the end of blocks are the same as for compressed databases. check-in: c93bae9496 user: dan tags: trunk
2012-11-05
16:41
Remove the unused LSM_WORK_FLUSH flags. check-in: dba97f861c user: dan tags: trunk
14:56
Merge range-delete-fixes branch with trunk. check-in: 7605250294 user: dan tags: trunk
14:33
Before writing data to a new database segment, make sure the data is held in heap (not mmap'd) memory. Otherwise, the write may cause the file to grow and the mapping to be released and remapped, leaving an invalid pointer. Leaf check-in: 3ba1c3f589 user: dan tags: range-delete-fixes
10:23
Fix a bug in compressed database mode causing an incorrect page number to be assigned to a page record when the end of the previous record is aligned with the end of a database block. check-in: e6a71a8583 user: dan tags: range-delete-fixes
2012-11-03
19:51
Fix a problem in writing free-list entries to the LSM. check-in: b3b4c58d9a user: dan tags: range-delete-fixes

2012-11-02
20:13
Change free-list deletes to use range-deletes instead of point-deletes (so that they can be coalesced when segments are merged). This has revealed problems with the range-delete code. check-in: 9374c3a283 user: dan tags: range-delete-fixes
2012-11-01
15:16

Fix a crash in the check-blocks assert that may occur following an OOM condition. Leaf check-in: 503f49b0cc user: dan tags: freelist-rework
18:46
Remove dead code. Fix a read-lock related problem causing the multi-threaded tests to fail. check-in: f512ea3c4d user: dan tags: freelist-rework
16:37
Fix a compressed mode bug unrelated to the free block list. check-in: 6bf6b00b8b user: dan tags: freelist-rework
11:15
Improve the complex assert() used to check that database file blocks are not leaked or over-allocated. check-in: 1ac4435e5c user: dan tags: freelist-rework
09:25

2012-10-30
18:46
Another free-list related fix. check-in: a8acce6c87 user: dan tags: freelist-rework
17:34
Avoid writing completely empty segments to the snapshot. check-in: 803f36b62f user: dan tags: freelist-rework
17:19
Fix another free block list related bug. check-in: f9e75777b0 user: dan tags: freelist-rework
16:27
Fix a couple of problems in the code that handles free block lists. check-in: 5c3e17cc90 user: dan tags: freelist-rework
2012-10-29
20:04
Rework the free block list storage so that it scales properly. Currently some test cases fail. check-in: ebca1063ac user: dan tags: freelist-rework
09:19
Fix a couple of crashes and a memory leak in OOM tests. check-in: 90f46bd082 user: dan tags: trunk

Turn off LSM_CONFIG_MMAP automatically in compressed database mode. Leaf check-in: 676da8516d user: dan tags: compression-hooks
11:28
Enhance the file-format to allow padding records smaller than 6 bytes in length. check-in: 2ba0368e76 user: dan tags: compression-hooks
10:07
Add padding records to segments in compressed databases in order to avoid partial writes to segments that have already been synced to disk. check-in: ae3c8da44d user: dan tags: compression-hooks
2012-10-27
08:57
Change the format of compressed page records slightly so that the file format supports inserting padding records into sorted runs. check-in: 0b940bfe17 user: dan tags: compression-hooks
2012-10-26
18:08
Enable assert() checking for lost blocks in compressed database mode. check-in: 6e7bc9099c user: dan tags: compression-hooks

Fix bug reading page data from a compressed database that occurs when the last page of a segment ends on the last byte of a block. check-in: 549868a020 user: dan tags: compression-hooks
2012-10-24
19:54
Have lsmtest use zlib for compression if HAVE_ZLIB is defined. This causes at least one test to fail. check-in: 8670182769 user: dan tags: compression-hooks
18:33
Fix memory leaks in compressed database mode. check-in: 083e3a6c0f user: dan tags: compression-hooks

13:13
Rename "storage.c" to "kv.c". Similar renames for test modules. This is to match the rename of "storage.h" to "kv.h" in a prior check-in. check-in: 7d290a04e8 user: drh tags: trunk
13:01
Change the "TK_" macro prefix in lsm_tree.c to "TKV_" in order to avoid name collisions with "TK_" macros generated by the parser. check-in: b81bc323b9 user: drh tags: trunk
