10:43
In zonefile, change the "file TEXT" column back to "fileid INTEGER". The fileid can be used as a key with the associated zonefile_files table, which contains more information than just the filename. check-in: 38d23888 user: dan tags: zonefile
01:48
Remove an unreachable branch in the walIndexPage() logic. check-in: 4e61a973 user: drh tags: trunk

Instead of just the frame number, store frame sizes and offsets in zonefile shadow table %_shadow_idx. check-in: 56801c46 user: dan tags: zonefile
17:02
In the speed-check.sh script, make WAL mode the default. Add the --legacy option to do DELETE mode.

16:39
Remove a superfluous "#if 1". No logic changes. check-in: caaffd32 user: drh tags: trunk
15:23
Optimize calls to sqlite3_mprintf("%z...") so that they attempt to append text onto the end of the existing memory allocation rather than reallocating and copying. check-in: 4bc8a48e user: drh tags: trunk
13:46
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
2018-02-19
22:46
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

18:56
Fix the %c substitution in printf() so that it works with unicode characters. check-in: c35be1d9 user: drh tags: printf-enhancement
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

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

07:38
Fix a data race causing a tsan complaint with SQLITE_ENABLE_API_ARMOR builds on unix. The race condition is not dangerous in practice, it just upsets tsan. check-in: f53b8a57 user: dan tags: trunk
2018-02-15
21:00
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

2018-02-14
23:27
Add the --readonly option to the ".open" command in the CLI. check-in: 06870bb1 user: drh tags: trunk

Improved test cases for the [f484b65f3d6230593c34f] bug. check-in: 1f300514 user: drh tags: trunk
19:01
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
2018-02-12
20:50
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

2018-02-10
21:04
Add start of "zonefile" virtual table. check-in: 0b7bd169 user: dan tags: zonefile
17:41
Add the start of the "zonefile" extension. check-in: c125b4c3 user: dan tags: zonefile
02:31
Fix misplaced testcase() macros from the previous check-in. check-in: 3aed949a user: drh tags: trunk
2018-02-09
23:25
Improve the performance of the built-in REPLACE() function in cases where it does many substitutions that make the string larger. OSSFuzz is reporting intermittant timeouts when running a test where it does a REPLACE() on a 930KB random blob. Perhaps this enhancement will fix that. check-in: fab2c2b0 user: drh tags: trunk
20:49
Add the zorder.c extension implementing zorder() and unzorder() SQL functions. check-in: a57a77dc user: drh tags: trunk

2018-02-07
18:45
Fix typo in comment. Skip tests added by check-in [4761db83b6] when running on Windows. check-in: 468a389c user: mistachkin tags: trunk
18:02
In extensions rtree, fts3 and fts5, ensure that when dynamic buffers are bound to persistent SQL statements using SQLITE_STATIC, the binding is replaced with an SQL NULL before the buffer is freed. Otherwise, a user may obtain a pointer to the persistent statement using sqlite3_next_stmt() and attempt to access the freed buffer using sqlite3_expanded_sql() or similar. check-in: 2a5f813b user: dan tags: trunk
16:14
When the final connection disconnects from a wal mode database, check that the database file has not been moved or unlinked before deleting the wal and shm files. check-in: 4761db83 user: dan tags: trunk
2018-02-05
21:02
Adjust the previous check-in, which modified the Win32 VFS, so that it works with SQLITE_OMIT_WAL. check-in: 36c2e67e user: mistachkin tags: trunk
20:42
Allocation the mutex used by the Win32 VFS only once at initialization, instead of every time it is needed. check-in: 535ed0ac user: mistachkin tags: trunk
16:39
Allocation the mutex used by the unix VFS only once at initialization, instead of every time it is needed. check-in: 5764dc16 user: drh tags: trunk
13:42
Fix another minor problem in walro2.test. check-in: ba0631de user: dan tags: trunk
13:28
Update test file walro2.test to account for systems with a page-size (getpagesize()) larger than 32KB. check-in: d9e59cfb user: dan tags: trunk
2018-02-04
20:33
In the CLI, make sure sqlite3_initialize() is called correctly even for non-UTF8 hosts. check-in: a3591fb5 user: drh tags: trunk
01:30
Fix harmless compiler warning seen with MSVC. check-in: 63a91441 user: mistachkin tags: trunk
01:29
Move variable declaration in zipfile extension to fix MSVC compiler error. check-in: ac6a3248 user: mistachkin tags: trunk
2018-02-02
16:46
Enable the ".wheretrace" and ".selecttrace" options in the shell when configure is run using --enable-debug. This mirrors a similar change that has already occurred on trunk. Leaf check-in: c4f798b2 user: drh tags: branch-3.9.2
16:28
Remove the "include <io.h>" win32 dependency from the zipfile extension. check-in: cb3feb3b user: dan tags: trunk
16:20
Remove the time() dependency from the zipfile extension. Use SQLite VFS methods instead. check-in: 0702fb56 user: dan tags: trunk
08:14
In SQLITE_ENABLE_BATCH_ATOMIC_WRITE builds on F2FS file-systems, invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE if an SQLITE_FCNTL_COMMIT_ATOMIC_WRITE call fails. Also, do not use an atomic transaction to create the initial database. This is because if an error occurs while writing to the db file, any changes to the file-size do not seem to be rolled back automatically. The only time this matters is when the file was 0 bytes in size to start with. Cherrypick of [b3122db154]. Leaf check-in: 22a228ed user: dan tags: branch-3.19
08:08
Update a couple of test scripts so that they work on F2FS file-systems that support atomic transactions. Cherrypick of [49e58e645e]. check-in: 1b394679 user: dan tags: branch-3.19
2018-02-01
20:42
Add a few more zipfile tests. No changes to code. check-in: 3f621545 user: dan tags: trunk
