18:24
In the output of the ".dump" command in the CLI, quote newline and carriage-return characters using the char() function, so that they do not get eaten by end-of-line processing logic in the OS or in other command-line utilities and/or libraries. check-in: 68f6dc7a user: drh tags: trunk

13:45
In the OSSFuzz test module, invoke the progress handler much more frequently so that timeouts are detected punctually even if the test script is running opcodes that individually take a long time (for example, an OP_Function opcode that invokes "randomblob(1.5e6)"). check-in: f3b6959c user: drh tags: trunk

01:05
Improvements to ".selftest --init". Tests are number in increments of 10 starting with 100. The tests are generated inside a SAVEPOINT. Errors are reported during test generation. Tests can be appended to existing tests. Add a test case to verify the schema. check-in: b044b152 user: drh tags: trunk
2017-03-09
22:00
Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old. check-in: f4fcd46f user: drh tags: trunk
18:13

17:56
In the ".sha3sum" command, if there is a LIKE pattern, show the hashes for each table separately. Without a LIKE pattern, show a single hash over the entire database. check-in: 30f87883 user: drh tags: trunk
16:10
Add the ".sha3sum" command to the CLI - used to compute a cryptographic hash of the content of a database file or of individual tables with in that file. check-in: fc663799 user: drh tags: trunk

If a reprepare is needed after binding to a variable with a number larger than 32, set only the high-order bit of the Vdbe.expmask rather than setting all bits. This could potentially result in fewer false-positive reprepares. check-in: 45797fee user: drh tags: trunk

14:51
When saving the state of an RBU update in the incremental-checkpoint phase, sync the database file. Otherwise, if a power failure occurs and the RBU update resumed following system recovery, the database may become corrupt. check-in: edee6a80 user: dan tags: trunk
