62 check-ins using file src/sqliteInt.h version 866311ac

2019-05-03
19:34
Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. check-in: 3a16ddf9 user: drh tags: trunk
18:50
Fix a memory-leak/segfault caused by using OP_OpenDup and OP_OpenEphemeral on the same VM cursor. check-in: a9b90aa1 user: dan tags: trunk
17:19
Fix a problem where self-joins on views that are aggregate queries may return the wrong result. check-in: 74ef97bf user: dan tags: trunk
17:08
Improved comments on the elements of the array constant used to implement the sqlite3_value_type() interface. check-in: f73a7de7 user: drh tags: int-real
02:41
Fix the ".open --hexdb" command in the CLI so that it works even with terminal input. check-in: 9b5d9434 user: drh tags: trunk
2019-05-02
21:36
Make MEM_IntReal a completely independent type, meaning a floating point value stored as an integer. This fixes a problem with arithmetic within arguments to string functions on indexes of expressions. But it is a big change and needs lots of new testcase() macros for MC/DC and so it is initially put on this branch. check-in: dba836e3 user: drh tags: int-real
17:45
Ensure that the typeof() function always returns SQLITE_FLOAT for floating point values even when the value is stored as an integer to save space. check-in: 48889530 user: drh tags: trunk
17:06
Add options to wapptest.tcl similar to those supported by releasetest.tcl. Also add the -noui switch, for running without wapp altogether. check-in: 005a1694 user: dan tags: trunk
15:56
Earlier detection of a database corruption case in balance_nonroot(), to prevent a possible use of an uninitialized variable. check-in: c509d8a8 user: drh tags: trunk
14:15
Merge enhancements from trunk Leaf check-in: 3a4751a9 user: drh tags: hard-heap-limit
01:41
The "LIKE Optimization" (which converts a LIKE into a BETWEEN operator that is able to use an index) does not work and cannot be used if the collating sequence of the column is not TEXT and if the pattern starts with a "+" sign. This is another case of ticket [c94369cae9b561b1f996d005]. The new test case was discovered by Manuel Rigger. check-in: b043a54c user: drh tags: trunk
00:52

2019-05-01
19:01

18:59
When values have real affinity and are converted into strings for CHECK constraints or index expressions, do the conversions into a real-number format even if the values are stored as integers for efficiency. This appears to fix ticket [ae0f637bddc5290b446]. check-in: 5997d075 user: drh tags: trunk
17:36
Fix an incompatibility with -DSQLITE_OMIT_LOAD_EXTENSION=1 in dbdata.test. check-in: a77cd85b user: dan tags: trunk
17:32

15:25

14:41
In "PRAGMA vdbe_trace" output, show the results of OP_Affinity opcodes. check-in: 56604bb6 user: drh tags: trunk
08:48

2019-04-30
20:43
Update wapptest.tcl to use a simpler slave script. And to leave scripts wapptest_configure.sh and wapptest_make.sh in each test directory. check-in: 07e527d7 user: dan tags: trunk
15:36

16:44
Changes to oserror.test so that it works even on systems that allow an unusually large number of file descriptors. check-in: a27b0b88 user: drh tags: trunk
13:48
Do not de-duplicate columns index columns associated with a WITHOUT ROWID table if the columns have different collating sequences. This is the fix for ticket [3182d3879020ef3b2]. There is one test case added, but most of the tests are done in TH3. check-in: 1b1dd4d4 user: drh tags: trunk
13:30
Improved header comment and precondition checking for the new isDupColumn() function. Closed-Leaf check-in: 740d5ff6 user: drh tags: tkt-3182d38790

2019-04-28
19:27
Take collating sequence into account when removing redundant columns from indexes on WITHOUT ROWID tables. This is the first proof-of-concept fix for ticket [3182d3879020ef3]. More testing needed. check-in: b34fa5bf user: drh tags: tkt-3182d38790
