|
2024-04-02
| ||
| 18:48 | Fix typos in comments. Provided ".wheretrace" debugging output for the interstage heuristic module. Do omit automatic index loops in the interstage heuristic. (check-in: 357d9513 user: drh tags: branch-3.28) | |
| 18:31 | Fix table-valued functions so that they will work as the right table in a LEFT JOIN. Ticket [2ae0c599b735d59e] (check-in: 1f97086d user: drh tags: branch-3.28) | |
| 11:54 | Add a heuristic in between the two solver() passes of the query planner that tries to prevent a very slow query plan in cases where the output row count estimate is imprecise. (check-in: 74b247d9 user: drh tags: branch-3.28) | |
|
2023-11-29
| ||
| 16:26 | Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (check-in: f10d4fc4 user: drh tags: branch-3.28) | |
| 16:07 | Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a7 user: drh tags: branch-3.28) | |
|
2023-10-19
| ||
| 21:05 | Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28) | |
|
2023-09-15
| ||
| 20:04 | Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28) | |
|
2023-02-26
| ||
| 11:52 | In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e user: drh tags: branch-3.28) | |

| 14:29 | Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 0163b697 user: drh tags: branch-3.28) | |
| 01:29 | Do not compute unused result columns of subqueries. This optimization will potentially resolve the performance optimization request of [ticket baa5bb76c35a124c]. (Closed-Leaf check-in: 0c21b6a5 user: drh tags: branch-3.26) | |
| 01:21 | Update test cases so that they work with TCL 8.7 and later. (check-in: e9b762de user: drh tags: branch-3.26) | |

| 13:00 | Update the configure script so that it contains the correct version number. (check-in: a7cbf308 user: drh tags: branch-3.26) | |
|
2022-12-18
| ||
| 10:27 | WIP, pre-sync-to-trunk check-in to capture extensive changes to shell source. (WASM and usual shell tweaks) (check-in: 3db119c8 user: larrybr tags: cli_extension) | |
|
2022-10-24
| ||
| 13:50 | Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de user: drh tags: branch-3.28) | |
|
2022-10-19
| ||
| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28) | |
|
2022-10-04
| ||
| 19:43 | Better handling for databases with corrupt headers. (check-in: 17f68d80 user: dan tags: recover-extension) | |

2022-10-01
| ||
| 12:04 | Note two wasm-related potential TODOs. (check-in: 5636e828 user: stephan tags: fiddle-opfs) | |
|
2022-09-30
| ||
| 23:49 | Remove a couple of weird quirks of the Worker1 and Promiser APIs. The Worker1 (now undocumented) unlink capability needs to be reevaluated to work equivalently for all storage backends. (check-in: 9f2b331a user: stephan tags: fiddle-opfs) | |
| 23:02 | Tweaks to the Worker1 and Promiser APIs prompted by documenting them. (check-in: c68b9aa1 user: stephan tags: fiddle-opfs) | |
| 20:35 | Add JS wrapper for sqlite3_exec() which knows how to handle a JS callback. Add some console.error() reporting of module-load failures, as they otherwise often get silently swallowed up by the loader's mechanisms. Add 'flexible-string' JS-to-WASM argument converter which performs more X-to-string conversions than the 'string' arg converter does. (check-in: 96818aa8 user: stephan tags: fiddle-opfs) | |
| 16:49 | Add sqlite3.version object. Add more state to the Worker #1 config-get response, including sqlite3.version. (check-in: 711f458d user: stephan tags: fiddle-opfs) | |
| 15:46 | Add oo1.JsStorageDb.clearStorage/storageSize() methods, copies of capi.sqlite3_web_kvvfs_clear/size(). (check-in: 1e09efe7 user: stephan tags: fiddle-opfs) | |
| 15:24 | batch-runner.js: force WebSQL batches to not abort for a failed statement (necessary for apples-to-apples-ish benchmark comparisons). (check-in: 60f0c5cb user: stephan tags: fiddle-opfs) | |
| 12:10 | Expose sqlite3_msize() to wasm. (check-in: aa6ad34f user: stephan tags: fiddle-opfs) | |
| 11:01 | Add oo1.JsStorageDb() as a convenience wrapper for oo1.DB(...,'kvvfs'). Minor doc cleanups. (check-in: 8a799870 user: stephan tags: fiddle-opfs) | |
| 10:55 | wasm: expose sqlite3_de/serialize(), sqlite3_malloc/free() and friends, noting that the former explicitly lies on use of the latter for memory management so is not generically safe for use in wasm. (check-in: fbc0edb5 user: stephan tags: fiddle-opfs) | |
|
2022-09-29
| ||
| 22:08 | Add JS infrastructure to ostensibly allow us to customize the wasm imports, which will hypothetically allow us to eliminate the dependency on EM_JS(), but the corresponding Emscripten glue-level feature currently breaks fatally with WASMFS builds so it's disabled. (check-in: 88d9253b user: stephan tags: fiddle-opfs) | |
| 17:35 | Ensure that the wasm builds always, even when passing -Ox flags from the CLI, use -g3 to avoid problems caused by symbol minification with optimization levels -O2 and higher. (check-in: 27d24d5d user: stephan tags: fiddle-opfs) | |
| 16:54 | Finish eliminating explicit Emscripten module dependencies in test code and fiddle. The only remnant in public code is the Emscripten-generated module load/init interface. (check-in: 7be78dd4 user: stephan tags: fiddle-opfs) | |
| 13:17 | Rework the Emscripten-emitted module loader/init function such that it passes on the sqlite3 module, instead of the Emscripten module, to the first then() of sqlite3InitModule()'s returned Promise. This eliminates any need to mention the Emscripten module object in client-side code unless they want to configure it in advance for loading-status reports. (check-in: 0dbaa0e2 user: stephan tags: fiddle-opfs) | |
|
2022-09-28
| ||
| 18:10 | Wasm: expose sqlite3_exec() and use it to simplify the db-reset logic in batch-runner.js a bit. (check-in: 2e2821f7 user: stephan tags: fiddle-opfs) | |
| 17:52 | More work on batch-runner.html/js to facilitate speed comparisons between various VFSes and WebSQL. (check-in: 3bd1bc24 user: stephan tags: fiddle-opfs) | |
| 13:01 | Correct duplicate copies of sqlite3-api.js being embedded in the wasmfs-based builds. (check-in: bbfcfba2 user: stephan tags: fiddle-opfs) | |
| 07:53 | Work around broken -Os wasm builds by adding the -g3 flag. Unrelated documentation tweaks. (check-in: f5d6bf86 user: stephan tags: fiddle-opfs) | |
|
2022-09-27
| ||
| 17:03 | Minor doc correction. (check-in: 093f6e4b user: stephan tags: fiddle-opfs) | |
| 17:00 | Fix a potential division by zero error in this version of RBU that might occur if an external client checkpoints a wal file created by a suspended RBU process. (Leaf check-in: 73edd93a user: dan tags: branch-3.14) | |
| 14:31 | Comment the -Os wasm builds as being broken (mysteriously missing JS bits). (check-in: f61475ef user: stephan tags: fiddle-opfs) | |
| 13:40 | WASM API renaming. Reworked JS API bootstrap's async post-init into a generic mechanism, no longer OPFS-specific. (check-in: c42a8cb0 user: stephan tags: fiddle-opfs) | |
| 09:17 | wasm/js: rename /persistent to /opfs to account for potential future persistent storage options. Minor flag-handling cleanups in the speedtest1 pages. Minor API tweaks in oo1. (check-in: 4dc972a3 user: stephan tags: fiddle-opfs) | |
| 00:56 | Enhance defensive mode so that it disallows CREATE TRIGGER statements if the statements within the trigger attempt to write on a shadow table. (check-in: 3283bbd1 user: drh tags: trunk) | |
|
2022-09-26
| ||
| 20:51 | Modify implementation of recovery to break recovery of the lost_and_found table into multiple steps. (check-in: adedfd04 user: dan tags: recover-extension) | |
| 13:55 | Fiddle: replace db export routine with a C-side one which works for both Emscripten FS-hosted and OPFS-hosted db files. Minor code-adjacent cleanups. (check-in: 3579a8d6 user: stephan tags: fiddle-opfs) | |
| 11:38 | Get fiddle db export working for OPFS VFS. Add root dir handle to the main OPFS VFS worker to enable creation of certain utility functions without delegating to the async worker. Add sqlite3.capi.sqlite3_wasm_rc_str() to map integer result codes back to their SQLITE_xxx counterparts. Minor doc touchups. (check-in: 9b2244e1 user: stephan tags: fiddle-opfs) | |
| 11:34 | wasm: change StructBinder signature for sqlite3_file::pMethods from 'P' to 'p' to eliminate an unnecessary and inconsistent level of magic. (check-in: 85f2e877 user: stephan tags: fiddle-opfs) | |
|
2022-09-24
| ||
| 19:54 | Add the SQLITE_RECOVER_SLOWINDEXES option, for specifying that indexes should be created and populated along with tables, instead of separately at the end of the recovery operation. (check-in: ad9dba9d user: dan tags: recover-extension) | |
| 19:17 | Add sqlite3_recover_step() to header file sqlite3recover.h. Update the API docs in this file. (check-in: 47f41615 user: dan tags: recover-extension) | |
| 18:05 | Update things to use sqlite3_recover_step() internally. (check-in: f4b15aad user: dan tags: recover-extension) | |
| 11:32 | Fiddle: move, rather than copy, data buffers between the threads. Fix the case of an uploaded db failing to install because its filename is the same as the opened db. (check-in: bcec4f96 user: stephan tags: fiddle-opfs) | |
| 10:15 | Resolve "already configured" warnings from shell's main() when starting it up in fiddle mode. (check-in: 114ef355 user: stephan tags: fiddle-opfs) | |
| 10:12 | Reworked out the OPFS async proxy metrics are fetched so that they play more nicely with the tight event-polling loop. (check-in: ef503ced user: stephan tags: fiddle-opfs) | |
| 07:36 | Refactoring towards getting fiddle to support OPFS as a first-class citizen. Certain operations, e.g. import, export, and unlink, are not OPFS-aware. (check-in: 1b923ed6 user: stephan tags: fiddle-opfs) | |
|
2022-09-23
| ||
| 21:01 | Internal changes to the recover extension towards a step() style interface. (check-in: 73926d5c user: dan tags: recover-extension) | |
| 11:40 | Fix various compiler warnings in new code on this branch. (check-in: ae49e9ef user: dan tags: recover-extension) | |
| 11:30 | Merge latest trunk changes into this branch. (check-in: e87fa70a user: dan tags: recover-extension) | |
|
2022-09-21
| ||
| 20:24 | Reformulate some JS to work around a buggy/broken code transformation in one of the Emscripten-driven code optimizers. (check-in: e1249369 user: stephan tags: fiddle-opfs) | |
| 19:51 | Put pieces in place for fiddle to support opfs, but more cleanup is required in the sqlite3.js/fiddle connection. bigIntEnabled now defaults to whether the Emscripten's module has bigint enabled. Add wasm-sensible defaults for several SQLITE_ENABLE/OMIT flags in sqlite3-wasm.c. (check-in: 7c7fb753 user: stephan tags: fiddle-opfs) | |
| 18:21 | Reduced and improved comments on the constraintCompatibleWithOuterJoin() function. (check-in: 38aaf26e user: drh tags: trunk) | |
| 16:21 | shell.c.in: when building in fiddle mode, define _POSIX_SOURCE (ifndef) so that emcc's string.h reveals strdup(). (check-in: fb85b269 user: stephan tags: fiddle-opfs) | |
| 14:02 | Correct mistyped --shrink-memory flag in speedtest1-worker. Minor OPFS proxy cleanups. (check-in: 86e2b55e user: stephan tags: fiddle-opfs) | |
| 12:27 | Doc cleanups and additions. Add a way for the OPFS async runner to propagate exception text to the calling thread. (check-in: 5c5e8065 user: stephan tags: fiddle-opfs) | |
| 12:25 | Added some structure to the wasm demo link list. (check-in: 777077c4 user: stephan tags: fiddle-opfs) | |
| 09:54 | The RIGHT JOIN logic added to version 3.39.0 added a new restriction on the query flattener which resulted in a performance regression for some queries, as documented by forum post 96b9e5709cf47cda. This change removes that restriction (thus restoring performance) and fixes the problem that RIGHT JOIN was having in a different way. (check-in: 501609ed user: drh tags: trunk) | |
| 08:41 | Add a link to fiddle.html in the wasm test app index.html. (check-in: 96c734c0 user: stephan tags: fiddle-opfs) | |
| 08:39 | Move fiddle build rules into the wasm-centric build files. Add rule to push wasm bits to the wasm test server. (check-in: 113f8204 user: stephan tags: fiddle-opfs) | |
| 00:16 | Break out the decision of whether or not a constraint term is usable by an outer join into a subroutine: constraintCompatibleWithOuterJoin(). (Closed-Leaf check-in: c7fbc9b0 user: drh tags: flattener-omit-restriction-29) | |
|
2022-09-20
| ||
| 22:19 | Do not allow EP_InnerON terms to be used on a outer join. (check-in: f47aa745 user: drh tags: flattener-omit-restriction-29) | |
| 21:07 | Add new test cases that (current) get an incorrect answer. (check-in: fe5c3773 user: drh tags: flattener-omit-restriction-29) | |
| 19:45 | New test cases for query flattening when there are ON clauses and outer joins. (check-in: db55387b user: drh tags: flattener-omit-restriction-29) | |
| 19:22 | Modify the OP_IfNotOpen opcode so that the jump is taken if the cursor is open but was previously set to a NULL row using OP_NullRow. (check-in: 1292d68c user: drh tags: flattener-omit-restriction-29) | |
| 18:18 | Remove code that has been previously commented out. (check-in: 852b385a user: drh tags: flattener-omit-restriction-29) | |
| 17:43 | Merge the fuzzcheck fix from trunk into the flattener improvement branch. (check-in: 930a8c15 user: drh tags: flattener-omit-restriction-29) | |
| 17:21 | Update the fuzz invariant checker to conform to the latest changes in dbsqlfuzz. (check-in: 8d8c1243 user: drh tags: trunk) | |
| 16:57 | Is the query flattener restriction 29 (do not allow both EP_InnerON and EP_OuterON constraints on the same FROM clause term) really necessary? This branch explores what happens if we omit that restriction. This is an effort to address the performance regression reported by forum post 96b9e5709cf47cda that is caused by flattener restriction 29. (check-in: 19270577 user: drh tags: flattener-omit-restriction-29) | |
| 16:20 | Correct a too-strict is-opfs-available check. (check-in: 1b5f1b4a user: stephan tags: fiddle-opfs) | |
| 16:10 | Merge kv-vfs-magic-names branch into fiddle-opfs branch and make some kvvfs-relevant tweaks. (check-in: e3d36dcd user: stephan tags: fiddle-opfs) | |
| 14:52 | Export the sqlite3_uri_...() family of functions to wasm. (check-in: 72bebc84 user: stephan tags: fiddle-opfs) | |
| 14:39 | Merge opfs-proxy-atomics branch into the fiddle-opfs branch. (check-in: 25a36920 user: stephan tags: fiddle-opfs) | |
| 14:36 | When compiled with SQLITE_OS_KV_OPTIONAL, the magic names ":localStorage:" and ":sessionStorage:" are recognized and converted to use the kv-vfs. (Leaf check-in: c5db9262 user: drh tags: kv-vfs-magic-names) | |
| 14:21 | Remove an obsolete file. (Closed-Leaf check-in: 1e438554 user: stephan tags: opfs-proxy-atomics) | |
| 13:25 | Speed up de/serialization of func args and return values in the OPFS VFS proxy. (check-in: 5bf235bb user: stephan tags: opfs-proxy-atomics) | |
| 10:47 | OPFS proxy: remove one sanity-checking-only level of proxy function to shave off a few microseconds. (check-in: b534831f user: stephan tags: opfs-proxy-atomics) | |
| 10:11 | Remove extraneous result-code SAB slots. Doc additions. (check-in: 88de2071 user: stephan tags: opfs-proxy-atomics) | |
| 08:27 |
An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). | |
| 03:31 | OPFS VFS: further internal refactoring towards experimenting with a new comms model. (check-in: 5ca412ce user: stephan tags: fiddle-opfs) | |
| 01:28 | OPFS VFS: moved i/o buffer from per-file to the VFS, and related refactoring, in prep for experimentation with a new inter-worker comms model. (check-in: d4d63e45 user: stephan tags: fiddle-opfs) | |
|
2022-09-19
| ||
| 19:25 | Clarify comments that describe query flattener restrictions associated with outer joins. No code changes. (check-in: 2647d73b user: drh tags: trunk) | |
| 18:22 | Further metrics and buffer-copy optimizations in the OPFS proxy, but with little effect. (check-in: d1f1fe6f user: stephan tags: fiddle-opfs) | |
| 17:41 | Fix a minor comment typo. No changes to code or documentation. (check-in: 8032db4a user: drh tags: trunk) | |
| 17:09 | Cut the speedtest1 runtime of the OPFS VFS proxy by approximately 3/4ths via xRead/xWrite buffer-copying optimizations. Still slower than the WASMFS impl by approx. 1/5th. (check-in: fb7f2873 user: stephan tags: fiddle-opfs) | |
| 14:56 | Remove an obsolete file. Update wasmfs build for today's changes. Fix the case that OPFS.xTruncate() is passed a BigInt instead of a Number. (check-in: 97605392 user: stephan tags: fiddle-opfs) | |
| 13:44 | Add sqlite3_web_vfs_list() to JS API. Corrected OPFS VFS's registering itself as the default VFS. speedtest1-worker now uses the xDelete() of both the default VFS and OPFS, to avoid that it starts up with a persistent OPFS test db (the native app calls unlink(), but that unlink call operates on a different virtual filesystem than the OPFS VFS). (check-in: 2ec7e091 user: stephan tags: fiddle-opfs) | |
| 13:16 | Merge kv-vfs branch into fiddle-opfs. Adjust various JS APIs and apps to deal with the new method of handling kvvfs. Adjust speedtest1 JS build to include sqlite3-api.js so that it can use kvvfs and opfs VFSes. Permit passing of the vfs as a URL parameter to certain demo/test apps. Milestone: speedtest-worker.html?vfs=opfs runs with the standalone OPFS impl. (check-in: ec09f32f user: stephan tags: fiddle-opfs) | |
| 11:47 | speedtest1: add --vfs NAME flag and eliminate code duplication in argc size verification for all flags which take a value. (check-in: 281d0986 user: stephan tags: fiddle-opfs) | |
| 10:13 | Minor doc improvements in demo-123.js. (check-in: 9370ce94 user: stephan tags: fiddle-opfs) | |
| 09:58 | Generic cleanups in the OPFS VFS proxies. (check-in: 7d5f6adc user: stephan tags: fiddle-opfs) | |
| 09:25 | Correct OPFS VFS xRead() to copy the result buffer if the result code is SQLITE_IOERR_SHORT_READ. (check-in: 56668f99 user: stephan tags: fiddle-opfs) | |
| 05:19 | Replace OPFS VFS xSleep() impl with a more efficient one (no Worker round-trip needed). (check-in: b9773f16 user: stephan tags: fiddle-opfs) | |
| 03:57 | Rename demo-oo1.* to demo-123.* and add demo-123-worker.html, which runs the same demo via a Worker. Doc typo fixes. (check-in: 2e4a005b user: stephan tags: fiddle-opfs) | |
| 00:40 | Disable build of wasmfs-using components on aarch64 (ARM), as wasmfs won't build there. (check-in: 9a9eeebc user: stephan tags: fiddle-opfs) | |

| 17:59 | Remove a NEVER macro in defragmentPage() that dbsqlfuzz discovered can be true. crash-32d9312f145cdce41613573f6431d9a3e439e3d7 (check-in: 90403759 user: drh tags: trunk) | |
| 17:32 | Numerous cleanups in the JS bits. Removed some now-defunct wasm test files. Expose sqlite3.opfs object containing various OPFS-specific utilities. (check-in: 26e625d0 user: stephan tags: fiddle-opfs) | |
| 03:05 | Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. Rename x-sync-async.* to test-opfs-vfs.* Milestone: first successful test of OPFS without WASMFS. (check-in: b2abf60d user: stephan tags: fiddle-opfs) | |
| 02:35 | Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. (check-in: 1c660970 user: stephan tags: fiddle-opfs) | |
| 00:16 | Plug OPFS methods in to their sqlite3_vfs/io_methods counterparts. Add URL args to control debug output and running of sanity-checks in the OPFS init code. (check-in: a0e93ed2 user: stephan tags: fiddle-opfs) | |
|
2022-09-17
| ||
| 23:47 | Correct OPFS xRead() and xWrite() impls and add a very basic sanity test for them. (check-in: cd06cc67 user: stephan tags: fiddle-opfs) | |
| 23:29 | Implement OPFS xAccess(), albeit with more limited semantics than the VFS API calls for. Add a way for OPFS xDelete() to optionally recursively remove empty dirs left over after deleting a file. (check-in: c342b5d7 user: stephan tags: fiddle-opfs) | |

| 10:24 | Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. (check-in: 65765222 user: drh tags: trunk) | |

| 01:14 | Btree interface refactoring: (1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey() and modified to work only for table btrees with a rowid. (2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize() and modified to work with any btree. (3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are combined into a single sqlite3BtreePayloadFetch() routine.

| 21:18 | An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid.

Also change SQLITE_CONFIG_MMAP_LIMIT and SQLITE_FCNTL_MMAP_LIMIT to SQLITE_CONFIG_MMAP_SIZE and SQLITE_FCNTL_MMAP_SIZE, respecctively. The default mmap_size is now always 0, meaning that memory mapped I/O is off by default. There is a new compile-time option SQLITE_MAX_MMAP_SIZE that determines a hard upper bound on the mmap_size. Setting SQLITE_MAX_MMAP_SIZE to zero disables the memory-mapped I/O logic and causes it to be omitted from the build. An extra argument is added to SQLITE_CONFIG_MMAP_SIZE that can optionally lower the SQLITE_MAX_MMAP_SIZE at start-time. The SQLITE_MAX_MMAP_SIZE is zero for platforms where we know that it does not work, meaning that it cannot be turned on by mistake on those platforms. (check-in: ea1404a1 user: drh tags: trunk) | |
