2019-08-03
01:40
Add the SQLITE_TESTCTRL_PRNG_SEED which can control the PRNG seed either directly or through the schema cookie of a supplied database connection. (check-in: 2660e9292a user: drh tags: trunk)
01:39
Give the SQLITE_TESTCTRL_PRNG_SEED two arguments. The second argument if not NULL is a pointer to a database connection which seeds the connection from its schema cookie. In this way, fuzzers can control the PRNG seed. (Closed-Leaf check-in: 49aa344806 user: drh tags: prng-seed-test-control)
2019-08-02
21:03
Fixes to the PRNG_SEED pragma idea. (check-in: c71098409c user: drh tags: prng-seed-test-control)

19:40
If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Fix for ticket [41866dc37]. (check-in: faaaae4940 user: dan tags: trunk)
18:43
If a query like "SELECT min(a), b FROM t1" visits no rows where "a" is not null, extract a value for "b" from one of the rows where "a" is null. Possible fix for ticket [41866dc37]. (Closed-Leaf check-in: a7277ed062 user: dan tags: tkt-41866dc37)
2019-08-01
22:48
The sqlite3_set_authorizer() interface should only expire prepared statements when it is setting a new authorizer, not when clearing the authorizer. And statements that are running when sqlite3_set_authorizer() is invoked should be allowed to continue running to completion. (check-in: 961e2f08c3 user: drh tags: trunk)
15:18
Add new release tests for windows to releasetest_data.tcl. (check-in: 1b330ec24c user: dan tags: trunk)

2019-07-31
21:08
Update "releasetest_data.tcl" so that it is a standalone script that generates sh or batch scripts to run each tcl test run at release time. Update wapptest.tcl to use it. (check-in: 559c2dd672 user: dan tags: trunk)
15:16
New test cases in test/fuzzdata8.db. (check-in: 6e92d71c24 user: drh tags: trunk)

21:00
Fix the build for when -DSQLITE_SMALL_STACK is used. (check-in: b9eda2249a user: drh tags: trunk)
14:22
Improved fix for ticket [ced41c7c7d6b4d36] that keeps skip-scan enabled, but avoids identifying a skip-scan as order-distinct (because it is not) and thus forces a separate b-tree to implement the DISTINCT clause of a query. This undoes check-in [a871d69c6de65038] and substitutes a new fix. (check-in: 89bf0399e8 user: drh tags: trunk)
01:17
Disable the skip-scan optimization for DISTINCT queries. Fix for ticket [ced41c7c7d6b4d36] (check-in: a871d69c6d user: drh tags: trunk)

14:42
When using an index for both DISTINCT and ORDER BY, do not confuse the number of columns required for distinctness with the number required to get the correct sort order. Fix for [6749cb3c]. (Closed-Leaf check-in: b47169319a user: dan tags: tkt-6749cb3c)
06:06
Fix the OP_Affinity operator so that when applying REAL affinity, it only sets MEM_IntReal if the integer value will fit in 6 bytes or less. Fix for ticket [ba2f4585cf495231] (check-in: 2b221bb15f user: drh tags: trunk)
05:23
Fix a minor typo in a comment. (check-in: cea8a892f7 user: drh tags: trunk)

Fix faulty asserts in the code generator. Ticket [c52b09c7f38903b1] (check-in: 01cdc590f7 user: drh tags: trunk)
20:10
Improve the ".recover" command so that it handles intkey pages linked into non-intkey b-trees, and vice-versa, better. (check-in: 9c458acba5 user: dan tags: trunk)
19:20
Improve the ".recover" command's handling of corrupt database schemas. (check-in: becaaa4d29 user: dan tags: trunk)
08:15
Improve the ".recover" command in the shell tool so that it is not confused by auto-vacuum databases. And so that it can recover tables for which one or more of the column names are SQL keywords. (check-in: 87d76047d6 user: dan tags: trunk)
2019-07-23
