And the kind of corruption that the bug causes can usually be fixed simply by running VACUUM. An analysis of the problem suggests that the bug might be able to cause database corruption, however focused efforts to find a real-world test cases that actually causes database corruption have so far been unsuccessful. Two bugs have been fixed that might cause incorrect query results. SQLite version 3.6.14.1 is a patch release to version 3.6.14 with minimal changes that fixes three bugs. What are the three sizes of pool tables? There are potential incompatibilities with some legacy applications. Non-recursive triggers are still the default behavior since this is least likely to cause problems for existing applications. Version 3.5.0 of SQLite changes the behavior of a few APIs in ways that are technically incompatible. SQLite version 3.7.0 also contains some query planner enhancements and a few obscure bug fixes, but the only really big change is the addition of WAL mode.

This is a large change. The change log contains the details. See the 35to36.html document for details. String processing, filesystem utils, branching,& other common utilities (like those I frequently see vendored into every C program, but in a shellscript). We can not verify these reports, but as locking is difficult to get right on a network filesystem we have no reason to doubt them. If you are running on a system that is vulnerable to this kind of filesystem namespace corruption (most modern journalling filesystems are immune, we believe) then you might want to consider putting each SQLite database file in its own private subdirectory. Version 3.5.4 fixes a long-standing but obscure bug in UPDATE and DELETE which might cause database corruption. Locating/testing various programs which might be needed to compile your project. The information in this article applies only when SQLite is operating in "rollback mode", or in other words when SQLite is not using a write-ahead log. The idea behind the rollback journal is that it contains all information needed to restore the database back to its original state. This release fixes a bug that was introduced into SQLite version 3.6.4 and that can cause database corruption in obscure cases.

STAT2 compile-time option has been added to cause SQLite to collect histogram data on indices when the ANALYZE command is run. The xargs command, which is very handy in conjuction with find probably hence why it’s bundled with them, reads each line from stdin to pass them to a specified command. The ".genfkey" command in the Command Line Interface has been removed. A typo in the OS/2 interface has been repaired. I’ve talked to a number of professional GC hackers-this is something you can build an entire career on-and read a lot of the literature, and all of the answers I got were . The standard size for a pool table used in professional tournaments is 9 feet by 4.5 feet. This release also brings the processing of ORDER BY statements into compliance with standard SQL. SQL function implementation to retrieve its database connection handle. Formerly, SQLite (as most other SQL database engines) supported IS NULL and IS NOT NULL. If the database was modified, then the user space cache must be cleared and reread. The 3.7.1 release adds new experimental methods for obtained more detailed memory usage information and for controlling database file fragmentation. This is a quick turn-around release that fixes a bug in virtual tables and FTS3 that snuck into version 3.6.5. This release also adds the new application-defined page cache mechanism.

A subset of the TH3 test suite was measured by gcov to provide 100% branch test coverage over the SQLite core (exclusive of the VFS backend and of extensions such as FTS3 and RTREE) when compiled for SuSE 10.1 Linux on x86. VFS layer in order to address deficiencies in the original design. Version 3.6.0 makes changes to the VFS object in order to make SQLite more easily portable to a wider variety of platforms. Those that survive are now considered one generation older, and the GC tracks this for each object. The garbage collector doesn’t need to worry about them at all, so the first thing we do is ensure that the value is an actual heap object. To capture all cases where the selected need to be rematerialized requires a second subpass taking into account control flow. Taking care of some edgecases. Beginning with this release, the SQLite source code is tracked and managed using the Fossil distributed configuration management system. SQLite was previously versioned using CVS. SQLite version 3.6.3 fixes a bug in SELECT DISTINCT that was introduced by the previous version. The bug has nothing to do with the versions 3.7.1 or 3.7.0 or any other recent release.
