2023-07-28
| ||
| 13:52 | JSON performance improvements: (1) Add a cache for large string values on OP_Column to avoid having to extract the string multiple times. (2) Internal JSON caching improvements. (check-in: 771fe350 user: drh tags: trunk) | |
| 11:30 | Mark an unreachable branch as ALWAYS(). (Closed-Leaf check-in: 8fd06d11 user: drh tags: json-opt) | |
| 00:54 | Remove some unnecessary and incorrect code that was mistakenly added in the previous check-in. (check-in: d3f458dc user: drh tags: json-opt) | |
|
2023-07-27
| ||
| 23:51 | Switch to using jsonParseCached() for json_patch(). (check-in: 2ed9c59e user: drh tags: json-opt) | |
| 20:28 | If the input JSON to a json function that uses cache comes from an RCStr value, then use that RCStr value in the parse rather than making a copy. (check-in: 509ae9c1 user: drh tags: json-opt) | |
| 19:39 | The OP_Column opcode caches large column values coming from overflow pages. (check-in: ab1edcc7 user: drh tags: json-opt) | |
| 18:19 | Merge trunk enhancements into the json-opt branch. (check-in: 5739a16a user: drh tags: json-opt) | |
| 17:50 | Dynamically determine whether the wasm.xWrap() argc check can be applied, depending on how the wasm environment exposes its exports. (check-in: fd59226b user: stephan tags: trunk) | |
|

| ||
| 14:18 | Improved caching and reuse of JSON parses. (check-in: df099ad7 user: drh tags: trunk) | |
| 13:17 | Change the debugging "json_parse(X)" function so that it shows a more complete description of the JsonParse object on standard output and returns the mimified JSON. Former behavior was to return the text of a decode of the aNode array. (check-in: 1bf85d4e user: drh tags: json-opt) | |
| 11:53 | More comment improvements in json.c. Do not run jsonLookup() following an OOM error. (check-in: cd5fda8c user: drh tags: json-opt) | |
| 11:43 | Improved comments and other cleanup for the changes on this branch. (check-in: bac953a8 user: drh tags: json-opt) | |
| 11:00 | Fix jsonForceRCStr() to also add the NULL terminator. (check-in: 134b01f3 user: drh tags: json-opt) | |
| 01:15 | Merge the latest trunk fixes into the json-opt branch. (check-in: ef4e1664 user: drh tags: json-opt) | |
| 01:12 | Add the concept of an RCStr string - a "Reference Counted String". Use these to keep track of big JSON strings that might need to be used in multiple places at the same time with different lifetimes. Add two different JSON string values to each parse - one with and one without changes. The net result is a large reduction in the number of parses that occur when doing an UPDATE of a indexed JSON field using json_replace() or similar. (check-in: a4c1af61 user: drh tags: json-opt) | |
| 01:05 | Extend the enhancement to json_set() and json_replace(). Clean up cruft. (Closed-Leaf check-in: 2dbb22c7 user: drh tags: json-opt-rcstr) | |
|
2023-07-25
| ||
| 17:54 | Fix a harmless "set-but-not-used" compiler warning in sqlite3session.c. (check-in: 54b3c43f user: dan tags: trunk) | |
| 15:08 | Create the new RCStr class of strings and try to use them for JSON storage. (check-in: c1b87250 user: drh tags: json-opt-rcstr) | |
| 00:13 | First attempt to cache modified JSON parses. Does not work. This is an incremental check-in. (Leaf check-in: 075eb09a user: drh tags: json-opt-wcache1) | |
|
2023-07-24
| ||
| 23:27 | It is an error to try to insert a BLOB value into JSON. (check-in: 28c6e964 user: drh tags: json-opt) | |
| 22:45 | Clean up some #defines in json. (check-in: 327fff50 user: drh tags: json-opt) | |
| 22:34 | Rework the JSON parse structure to facilitate better caching. Passes all tests. (check-in: ecdcb1de user: drh tags: json-opt) | |
| 17:59 | Incremental progress toward improved caching of parsed JSON. (check-in: f2c06388 user: drh tags: json-opt) | |
| 12:37 | Merge the latest trunk enhancements into the json-opt branch. (check-in: 00bfc491 user: drh tags: json-opt) | |
|

| ||
| 22:14 | When writing the filename header in a opfs-sahpool file, ensure that all remaining bytes in that part of the header are zeroed out to avoid the downstream problems reported in forum post d50ec48a293988a5. (check-in: c1b080e3 user: stephan tags: trunk) | |
|
2023-07-21
| ||
| 11:09 | More infrastructure changes towards improving JSON cache performance. Incremental check-in. (check-in: 1955e66c user: drh tags: json-opt) | |
|
2023-07-20
| ||
| 17:45 | Experimental framework upon which to build a better JSON parse structure that supports cached of modified JSON. All of these changes are tentative and subject to change or removal. Incremental check-in. (check-in: e384163a user: drh tags: json-opt) | |

2023-07-19
| ||
| 23:02 | Performance enhancements to the JSON parser and code generator. (check-in: 0a745897 user: drh tags: trunk) | |
| 17:24 | Further improvement to JSON parser performance. (check-in: 144c8ccf user: drh tags: json-opt) | |
| 15:06 | Further performance enhancements to JSON parsing and rendering. Total performance gain for large JSONs so far on this branch is about 11%. (check-in: adb4d6b0 user: drh tags: json-opt) | |
| 13:50 | Performance optimization for parsing large JSONs that contain lots of text. (check-in: c9fbe018 user: drh tags: json-opt) | |
| 09:52 | Two minor improvements to sum(), one of which was inspired by forum post af5be98dbc. (check-in: a0d3e757 user: drh tags: trunk) | |
