13:07
Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".

Remove a lot of the text describing extended format options from the documentation on sqlite3_mprintf() and friends, since that information is now covered by the separate printf.html document. Provide links to that other document. No changes to code. (check-in: 99eec556 user: drh tags: trunk)

Enhance the string formatter (used by printf()) so that the width and precision of string substitution operators refer to characters instead of bytes when the alternate-form-2 flag ("!") is used. Also fix the %c substition to always work within unicode, regardless of the alternate-form-2 flag. (check-in: c883c4d3 user: drh tags: trunk)
21:58
Printing a value of 0 using %c terminates the string. (Closed-Leaf check-in: 255612f0 user: drh tags: printf-enhancement)
21:07
Add support for invoking encryption hooks to zonefile. And mock encryption method "xor" for testing. (check-in: 55cf920c user: dan tags: zonefile)

18:03
Make the alternate-form-2 flag ("!") change the meaning of width and precision from bytes to characters for the %q, %Q, and %w extensions of printf(). (check-in: 391540ac user: drh tags: printf-enhancement)
17:03
In the printf() library, measure width and precision in characters rather than bytes if the "!" (alternate-form-2) flag is present on a %s or %z substitution. (check-in: ca31c663 user: drh tags: printf-enhancement)
16:34
Only try to use the geteuid() interface on unix if HAVE_FCHOWN is defined. This fixes the build for vxWorks, we are told. (check-in: 38f654dc user: drh tags: trunk)
16:28
Add support for the ExtendedHeaderSize header field to zonefile. (check-in: 78267a09 user: dan tags: zonefile)
14:27
Modify the zonefile format in order to avoid depending on the filesize to determine the extent of the final frame. See README.md for details. (check-in: 4dbe0cba user: dan tags: zonefile)
13:53
Fix an assert so that it compares two CellInfo objects field by field instead of using memcmp(). Memcmp() does not work on x86 because of uninitialized padding bytes. (check-in: 88258770 user: drh tags: trunk)
2018-02-18
17:50
Fix a memory leak in the processing of nested row values. This problem has existed every since row values support was added (version 3.15.0, 2016-10-14) but was only just now detected by OSSFuzz. (check-in: 2df6bbf1 user: drh tags: trunk)
00:54
Port mutex enhancments from check-in [f53b8a573b] to the Win32 implementation. (check-in: 74bb7225 user: mistachkin tags: trunk)

Do not allow parameters or schema references inside of WITH clause of triggers and views. This fixes a bug discovered by OSSFuzz and present since common-table-expressions were first added in 2014-02-03. (check-in: b918d4b4 user: drh tags: trunk)
20:37
Add support for zlib compression to the zonefile module. (check-in: 72b8a7ef user: dan tags: zonefile)
20:00
On unix, the "PRAGMA fsync_interval=N" command causes an extra fdatasync() after writing N bytes of content, to force a write-queue flush in the underlying OS. This is an experimental hack that is not expected to land on trunk. (Leaf check-in: b18cc5fe user: drh tags: write-queue-flush-hack)
15:24
Fix another point in zonefile.c so that all files are opened in either "rb" or "wb" mode. (check-in: fb1c2277 user: dan tags: zonefile)
15:17
When calling fopen() in the zonefile extension, use modes "rb" and "wb" instead of "r" and "w". This makes no difference on unix, but is required when accessing binary files on other systems. (check-in: 4bb854dd user: dan tags: zonefile)
03:56
Improve performance of editdist3() by keeping the costs in sorted order. Also add a new regression test to editdist3(). (check-in: dc734c5b user: drh tags: trunk)

Enhance ext/zonefile/README.md to describe the currently available functionality. (check-in: 100137c7 user: dan tags: zonefile)
18:48
Fix an incorrect table lookup used to find the appropriate search operator for a WHERE clause on a row-value inequality. The incorrect table lookup was causing an incorrect answer for the less-than operator. Fix for ticket [f484b65f3d6230593c34f11] (check-in: f3112e67 user: drh tags: trunk)
18:02
Remove, for now, the "priority" column from the zonefile_files virtual table. (check-in: 8bf5154b user: dan tags: zonefile)
17:33
Pad the 26 byte Zonefile header to 32 bytes so that the ZonefileIndex object is 8-byte aligned. (check-in: fdb6c0c5 user: dan tags: zonefile)
16:30
Remove an unused variable from FTS4. (check-in: 27ea783b user: drh tags: trunk)
16:21
Ensure that multiple updates of the same FTS4 row (i.e. the row with the same rowid) within a single transaction are written to separate segments. Fix for [d6ec09ec]. (check-in: d2a81a37 user: dan tags: trunk)

Updates to the speed-check.sh script for improvements to the --vdbeprofile option. (check-in: f89c8f8e user: drh tags: trunk)
20:27
When compiling with VDBE_PROFILE, add the sqlite3NProfileCnt global variable which can be used to measure per-opcode values other than elapse time, if non-zero. (check-in: d44d5936 user: drh tags: trunk)
20:04
Add support for reading simple (no compression, no encryption) zonefile files. (check-in: dba42f0e user: dan tags: zonefile)
