2016-01-26Fix a race bug affecting dets_SUITE:open_file/2Hans Bolinder
The Dets server pretends the file is open before internal_open() has been called, which means that unless the internal_open message is applied first, other processes can find the pid by calling dets_server:get_pid() and do things before Head has been initialized properly.
2016-01-20Introduce time warp safe replacement for safe_fixed optionRickard Green
The new time warp safe option is safe_fixed_monotonic_time which gives erlang:monotonic_time(). The safe_fixed option was also slightly changed. It now gives erlang:timestamp() instead of erlang:now(). This has however not been documented, so it is considered a compatible change. The above effects both ets, and dets. This commit also include the bugfix OTP-13239 for dets:info(Tab, safe_fixed). The timestamp in the result returned by dets:info(Tab, safe_fixed) was unintentionally broken as a result of the time API rewrites in OTP 18.0.

2014-10-23Fix rare race condition in DetsHans Bolinder
The correction is due to the the evil testcase dets_SUITE:simultaneous_open(). If the process repairing a Dets file is killed (should normally never happen), and another process tries to repair the file, a temporary file from the first process could live on for a while, even after a successful call to file:delete(). This has only been seen on W-nd-ows, where it is a known problem. There are other ways to deal with the problem (rename the file; use some other filename), but we continue using one certain filename in order to be as backwards compatible as possible.
2014-06-30stdlib: Correct documentation of dets:insert/2Hans Bolinder
Thanks to Alexei Sholik for reporting the bug.
2014-03-05stdlib: Fix a Dets bug where files were deletedHans Bolinder
Instead of deleting the small file when opening it with dets:open_file/2 an error message is returned, mimicking the behaviour when the file is bigger. open_file/1 has been modified to return the same error message when the file is small as when the file is bigger. Thanks to Hakan Mattson for reporting this bug.

2013-03-18Adjust dets.erl to cope with an evil test caseHans Bolinder
The test case deletes a Dets process while it is repairing a file. Another client waiting for the Dets process to reply then kicks in and repairs the file. Apparently the temporary file was still open, resulting in an eacces error on Windows.

Opaque types need to be exported.
2012-08-21Optimize traversal of Dets tables with bound keyHans Bolinder
Dets tables are no longer fixed while traversing with a bound key (when only the objects with the right key are matched). This optimization affects the functions match/2, match_object/2, select/2, match_delete/2, and select_delete/2.
2011-10-17Fix a bug in Dets concerning repair of almost full tablesHans Bolinder
A Dets table with sufficiently large buckets could not always be repaired. (Reported by Gordon Guthrie.) The format of Dets files has been modified. When downgrading tables created with the new system will be repaired. Otherwise the modification should not be noticeable.
2011-10-10Fix a minor bug in DetsHans Bolinder
If a Dets table had been properly closed but the space management data could not been read, it was not possible to repair the file.
2011-08-31Improve and correct types and specifications in Kernel and STDLIBHans Bolinder
Running Dialyzer on the test suites revealed a few type errors.

2010-10-21Fix a bug concerning bchunk(), match() and select()Hans Bolinder
If a Dets table was closed after calling bchunk/2, match/1,3, match_object/1,3, or select/1,3 and then opened again, a subsequent call using the returned continuation would normally return a reply. This bug has fixed; now the call fails with reason 'badarg'.

2010-10-21Fix a bug that could cause 'bad_object' errorsHans Bolinder
When several clients accessed a Dets table simultaneously, modifications of the Dets server's internal state were sometimes thrown away. The symptoms are diverse: error with reason 'bad_object'; inserted objects not returned by lookup(); et cetera.
2010-10-21Fix a bug concerning truncated Dets filesHans Bolinder
When several clients accessed a Dets table simultaneously, inserted or updated objects were sometimes lost due to the Dets file being truncated.
