100 check-ins occurring around 77bb46233d.

2017-06-28
15:17
Fix harmless compiler warnings in the CSV extension. (check-in: f02a54599d user: drh tags: trunk)

Minor tweak to the SQL grammar to make the parser tables a few bytes smaller. (check-in: cc4810b23e user: drh tags: trunk)
13:47
In the lemon-generated parser, store the number of symbols on the RHS of each rule as a negative number and add it to the stack pointer, rather than storing the value as a positive and subtracting it. This makes the parser faster. (check-in: b362f0d8ed user: drh tags: trunk)
11:56
In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. (check-in: c46d94a8cd user: drh tags: trunk)

Fix a virtual table problem that can occur when the vtab is on the RHS of a LEFT JOIN and there is a MATCH constraint in the ON clause, or when the vtab is in a sub-query that is the RHS of a LEFT JOIN and there is a MATCH constraint in the WHERE clause of the sub-query. (check-in: 87b3816633 user: dan tags: trunk)

18:42
The ".import" command of the shell, and the csv virtual table extension both ignore a single UTF-8 BOM at the beginning of their input. (check-in: 7c15d762d9 user: drh tags: trunk)
16:13
Add the "-unsetnull 1" option to the "sqlite3" command in the TCL interface. (Closed-Leaf check-in: cbe441b231 user: drh tags: unsetnull-option)

18:19
Rename the azCompileOpt global constant to avoid a harmless compiler warning about a name conflict with a local variable. (check-in: 94e420ecfb user: drh tags: trunk)
17:43

2017-06-19
11:44
Experimental "PRAGMA secure_delete=FAST" pragma. The intent is to overwrite deleted content with zeros without increasing the amount of disk I/O. (Closed-Leaf check-in: f1682f0faf user: drh tags: fast-secure-delete)
2017-06-17
19:06
Avoid adding an artifical "LIMIT 1" on scalar subqueries that do not need it. This seems like a pointless optimization as it makes minimal run-time difference but does increase code complexity. Parked on a branch for historical reference. (Leaf check-in: c21628e9c1 user: drh tags: subquery-limit-opt)
18:49

17:55
Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. (check-in: 9a443397a6 user: dan tags: trunk)
17:29
Ensure that the value of the THREADSAFE symbol is always included when reporting compile time options, even if it was not explicitly configured. (Closed-Leaf check-in: 95141c6426 user: dan tags: ctime-refactor)
16:39
Add extra test cases for sqlite3changeset_apply() and ALTER TABLE ADD COLUMN. (check-in: 603838fc9a user: dan tags: trunk)

00:39
When building an ephemeral table of integers, do not assume that the table does not already contain N if the insert cursor points to N-1. Fix for ticket [61fe9745]. Also increase the version number to 3.18.2. This is the release candidate. (check-in: e1b7102908 user: drh tags: branch-3.18)
2017-06-16
19:51
Rework the code in ctime.c a bit to report on more compile time options. And to only output configuration options passed in to SQLite, not the default values of #define symbols set automatically. Also generate the large array in ctime.c using new script tool/mkctime.tcl, instead of entering it manually. (check-in: bc1951d699 user: dan tags: ctime-refactor)
18:31
Minor refactoring change to clarify how ATTACH works. No functional changes. (check-in: 3944a32e1d user: drh tags: trunk)

An unintentional fork was created due to a typo when creating branch-3.18. This check-in resolves the fork and is the 3.18.1 release candidate. (check-in: 20e5ffb1ce user: drh tags: branch-3.18)
2017-06-15
16:56
Move the "shell_add_schema()" SQL function used by the ".schema" command of the command-line shell to a different spot in the shell.c source file so that it is not in the middle of an unrelated module. (check-in: 254617a1cc user: drh tags: trunk)
16:45
Fix typo and improve the wording of the description of "Metadata" in the output of the sqlite3_analyzer tool. (check-in: ca1ff70780 user: drh tags: trunk)
15:06
Merge the latest changes from trunk. (check-in: 60105c2253 user: drh tags: lsm-vtab)
13:07
Fix harmless compiler warnings in the shell.c file (check-in: 9afd7a2ffd user: drh tags: trunk)
12:50

12:21

2017-06-11
20:17
Fix an off-by-one error that messes up the display of loop codes in the ".wheretrace" debugging output for queries with more than 62 candidate loops when SQLITE_ENABLE_WHERETRACE is on. (check-in: 0bbdaf2801 user: drh tags: trunk)
19:51

2017-06-08
16:23
Update the recent auto-vacuum fix so that it works for the in-memory pointer-map structure used by this branch. (check-in: 8e311a6dba user: dan tags: begin-concurrent)
16:10

14:26
Version 3.19.3 (check-in: 0ee482a1e0 user: drh tags: release, version-3.19.3, branch-3.19)
11:32
Fix an issue with OPT_FEATURE_FLAGS in configure.ac. (check-in: 97b5c4a53d user: drh tags: branch-3.19)
11:27
Increase the version number to 3.19.3. (check-in: 903fff53b3 user: drh tags: branch-3.19)
11:26
Ensure pointer map entries are always added when a row that does use overflow pages replaces one that does not in an auto-vacuum database. Fix for [fda22108]. (check-in: 9478106ca9 user: drh tags: branch-3.19)
11:14
Ensure pointer map entries are always added when a row that does use overflow pages replaces one that does not in an auto-vacuum database. Fix for [fda22108]. (check-in: b30dfba811 user: dan tags: trunk)
2017-06-07
22:32

19:46
Fix another lsmtest build problem. Add the "-trans BOOLEAN" option to "lsmtest speed2". (check-in: 61853bc171 user: dan tags: lsm-vtab)
16:25
Merge in trunk enhancements. (check-in: f8bbb608cb user: drh tags: prepare_v3)
15:55
Add too/tserver.c - the implementation of a simple multi-threaded server designed for interactive testing of concurrency between connections used by different threads of the same process. (check-in: 05b4fc4340 user: dan tags: server-edition)
10:55
Cause the ANALYZE command to build sqlite_stat1 table entries for empty tables with the assumption that such tables really contain 10 elements. This gives better query plans for tables that are truely empty, but is likely to cause problems in legacy systems, so the change is kept off trunk. Some TCL tests fail on this check-in due to the new stat1 entries. (Leaf check-in: c81f260c2d user: drh tags: analyze-empty-tables)
2017-06-06
18:22
Add the SQLITE_DEFAULT_ROWEST compile-time option for changing the estimated number of rows in tables that lack sqlite_stat1 entries. (check-in: 802b82f342 user: drh tags: branch-3.8.9)

16:33
Fix a bug in test_fs.c that occurs when the first component of a path contains a GLOB or LIKE escape character. (check-in: 73c70590d7 user: dan tags: trunk)
13:28
For the kvtest utility, add the --vacuum option to "kvtest stat" and also run PRAGMA integrity_check with "kvtest stat". (check-in: f3c25df456 user: drh tags: trunk)

Initialize a variable to zero to prevent an (incorrect) compiler warning of it potentially being uninitialized. (check-in: 65182ce041 user: drh tags: trunk)
19:16
Fix the SQLITE_PTR_TO_INT macro so that works on recent versions of LLVM on Macs. (check-in: c4089ffbdb user: drh tags: trunk)
18:27
Remove unused header file from kvtest. (check-in: dd7e043f7c user: drh tags: trunk)
17:24

15:17
Add the --nocheckpoint and --multitrans options to kvtest. (check-in: 5828633c23 user: drh tags: trunk)
2017-06-02
23:44
Merge all recent trunk enhancements. (check-in: 1d23294d88 user: drh tags: lsm-vtab)
23:32
Add the --fsync flag to kvtest, and document the --nosync flag. (check-in: 7fdc78a672 user: drh tags: trunk)
