29 check-ins using file src/vdbe.c version 2d90c42f

2016-12-15
21:33
Fix the cost estimation in the BestIndex method of the eponymous pragma virtual table implementation. check-in: 7126807a user: drh tags: pragma-as-vtab
21:11
The pragma as eponymous virtual table mechanism now appears to work. check-in: 2c274a1a user: drh tags: pragma-as-vtab
20:59
Code to automatically create eponymous virtual tables for read-only pragmas. Compiles, but does not yet work. check-in: 988a61e8 user: drh tags: pragma-as-vtab
18:59
Do exponential rather than linear expansion of the SrcList.a array when appending new elements, to reduce the number of malloc() calls. check-in: 4e374912 user: drh tags: trunk
16:01
Do more pragma processing from tables rather than in-line code. Closed-Leaf check-in: a88ca352 user: drh tags: table-driven-pragma
06:01
Add the -groupbyparent option to the ".fkey_missing_indexes" command. check-in: 976c51b4 user: dan tags: fkey-missing-indexes
2016-12-14
19:28
Add the experimental ".fkey_missing_indexes" command to the shell tool. To identify indexes that should be created on child keys if FK processing is to be enabled. check-in: 7df23aca user: dan tags: fkey-missing-indexes
14:07
Refactor the Table.nRef field as Table.nTabRef for easier grepping. check-in: 9cae4c2e user: drh tags: trunk
13:54
Increase the size of the reference count on Table objects to 32 bits. check-in: d08b72c3 user: drh tags: trunk
11:39
Fix the configure makefile to align it with the manual makefile. Unsaved changes from the previous check-in. check-in: 00a184b6 user: drh tags: trunk
11:23
Adjust the unix makefiles so that "make test" runs fuzzcheck prior to even attempting to build the other test programs. check-in: bb48f7a5 user: drh tags: trunk
11:14
Three times faster sqlite3SrcListAppend() in the common case by avoiding the call to sqlite3SrcListEnlarge() for the first allocation. check-in: 0ea2762f user: drh tags: trunk
10:30
Fix the optimization that prevents writing freelist pages to the journal. check-in: 6aa9b265 user: drh tags: trunk
2016-12-13
23:22
In the command-line shell, in the output of the ".dump", ".schema", and ".fullschema" commands, convert CREATE TABLE statements that appear to come from shadow tables into CREATE TABLE IF NOT EXISTS statements. check-in: c7021960 user: drh tags: trunk
20:30
Fix harmless compiler warnings. check-in: ed2c9f37 user: drh tags: trunk
18:47
Convert sqlite3PagerGet() into a pointer-dispatched virtual method. This makes it about 25% faster. check-in: 7f88bb44 user: drh tags: trunk
18:34
In the pager, avoid checking for the illegal page number 0 except when creating a new page. Closed-Leaf check-in: dee20ba9 user: drh tags: pager-get-method
16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns. This bug did not cause SQLite to allow illegal data to be inserted into the database, only to reject legal operations. check-in: 850877d1 user: dan tags: trunk
15:53
Further refinements to the virtual method implementation of sqlite3PagerGet(). check-in: 67df4446 user: drh tags: pager-get-method
14:32
Make the sqlite3PagerGet() interface into a virtual method, with different implementations based on the current state of the pager. This gives a small performance increase by avoiding unnecessary branches inside the various methods. check-in: df5bb90d user: drh tags: pager-get-method
2016-12-12
23:24
Add the --mmap option to the speedtest1 program and to the speed-check.sh script that is frequently used to run speedtest1. check-in: 1a636d5e user: drh tags: trunk
18:12
Remove unnecessary MemPage initialization resets in the autovacuum ptrmap processing. check-in: 1b36fbb9 user: drh tags: trunk
16:08
Faster operation for large in-memory databases. check-in: 9675518b user: drh tags: trunk
11:05
Performance optimization in sqlite3PagerWrite(). check-in: d4dff10a user: drh tags: trunk
01:53
Updates to the tokenizer for EBCDIC. No changes for standard builds. check-in: 4fc6580f user: drh tags: trunk
01:30
Size and performance optimization in btreeInitPage() in the freeblock validation step. check-in: 57deb1b4 user: drh tags: trunk
00:58
Change the order of comparison for divider cell overflow in balance non-root to avoid a (harmless) reference to an uninitialized variable. check-in: f9f2e23b user: drh tags: trunk
2016-12-10
13:12
Avoid an unnecessary memset() in the sqlite3BtreeInsert() routine. check-in: 35ecd4eb user: drh tags: trunk
12:58
Reorder the fields in the VdbeCursor object so that those that need to be bulk zeroed on allocation are grouped at the beginning, and the memset() only runs over those fields that really need it. check-in: 8165f88b user: drh tags: trunk
