| 14:03 | [7af7e9ff] part of check-in [c6dfc59e] Fix to the error handling logic in the Lemon parser template. This does not affect SQLite since SQLite does not use that part of the Lemon parser template. (check-in: [c6dfc59e] user: drh branch: trunk, size: 36603) | |
|
2018-07-22
| ||
| 21:23 | [6020ce61] part of check-in [edab5666] Fix more harmless compiler warnings seen with MSVC. (check-in: [edab5666] user: mistachkin branch: trunk, size: 36636) | |

2018-07-01
| ||
| 16:05 | [a6ebc202] part of check-in [3f6730be] Quick patch to the Lemon parser template to avoid an array overread reported by OSSFuzz. A proper fix involves enhancements to the table generators in Lemon to make the overread impossible. That fix will take longer to implement. The current check-in is a stop-gap. (check-in: [3f6730be] user: drh branch: trunk, size: 36567) | |
|
2018-06-30
| ||
| 19:12 | [6f64bc81] part of check-in [aad718fb] Merge all changes from the weak-fallback branch except those related to the weak-fallback feature itself. (check-in: [aad718fb] user: dan branch: exp-window-functions, size: 36507) | |
|
2018-06-29
| ||
| 17:44 | [afc03d26] part of check-in [022079cb] Instead of using a lemon %fallback directive, have the tokenizer try to figure out whether an instance of "WINDOW" should be TK_WINDOW or TK_ID. (check-in: [022079cb] user: dan branch: weak-fallback, size: 36803) | |
|
2018-06-28
| ||
| 03:38 | [c7371bad] part of check-in [c41d7079] Introduce the concept of "weak fallback" in the parser. A weak fallback only occurs if a syntax error would result otherwise. (check-in: [c41d7079] user: drh branch: weak-fallback, size: 36528) | |
|
2018-04-23
| ||
| 00:25 | [bf7db78e] part of check-in [e3064ba3] Fix an unreachable branch associated with stack overflow in the LEMON-generated parser. (check-in: [e3064ba3] user: drh branch: trunk, size: 36162) | |
|
2018-04-21
| ||
| 22:40 | [01f28a4d] part of check-in [fec1ebad] Performance improvements on the main loop of the LEMON-generated parser. (check-in: [fec1ebad] user: drh branch: trunk, size: 36156) | |
| 13:51 | [8ce83cbe] part of check-in [be47a6f5] Add the %extra_context directive to lemon, as an alternative to %extra_argument. Use this to improve the performance of the parser. (check-in: [be47a6f5] user: drh branch: trunk, size: 35736) | |
|
2018-02-09
| ||
| 15:04 | [468a155e] part of check-in [a6c31154] Fix a harmless compiler warning. (check-in: [a6c31154] user: drh branch: trunk, size: 35159) | |

|
2017-12-27
| ||
| 17:36 | [dddd4f59] part of check-in [ec9b19eb] The previous check-in had an error in the coverage reporting logic. (check-in: [ec9b19eb] user: drh branch: lemon-improvements, size: 35095) | |
| 17:14 | [1b1279a3] part of check-in [9dce4650] Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. (check-in: [9dce4650] user: drh branch: lemon-improvements, size: 35084) | |
| 16:13 | [48ca9d9f] part of check-in [3fe96487] In the lemon-generated parser, do not report the End-of-input character and the wildcard character as missed coverage. (check-in: [3fe96487] user: drh branch: lemon-improvements, size: 34823) | |
|
2017-12-26
| ||
| 18:32 | [64e760f7] part of check-in [86e30fc2] Change the lemon-parser coverage report format to report all state/lookahead pairs and indicate on each whether it is hit or missed. (check-in: [86e30fc2] user: drh branch: lemon-improvements, size: 34787) | |
| 18:04 | [2a688bf3] part of check-in [1253a872] Add support for measuring and reporting coverage of the parser state machine using the SQLITE_TESTCTRL_PARSER_COVERAGE test-control. (check-in: [1253a872] user: drh branch: lemon-improvements, size: 34735) | |
|
2017-12-25
| ||
| 04:15 | [427ee280] part of check-in [7eb0198d] Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. (check-in: [7eb0198d] user: drh branch: lemon-improvements, size: 33701) | |
| 00:10 | [8062f219] part of check-in [fdbb35c5] In the LEMON-generated parser, avoid unnecessary tests for the acceptance state. (check-in: [fdbb35c5] user: drh branch: lemon-improvements, size: 34075) | |
|
2017-12-24
| ||
| 23:38 | [c8dd4dcf] part of check-in [7bfe7a36] In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. (check-in: [7bfe7a36] user: drh branch: lemon-improvements, size: 34082) | |
| 14:14 | [a427c237] part of check-in [c4951833] Improved parser tracing output. (check-in: [c4951833] user: drh branch: span-refactor, size: 34082) | |
|
2017-12-15
| ||
| 12:22 | [967ebf58] part of check-in [42af190f] In the LEMON parser generator, provide reduce actions with access to the lookahead token. (check-in: [42af190f] user: drh branch: trunk, size: 33531) | |
|
2017-10-02
| ||
| 02:32 | [105d0d9c] part of check-in [8000d230] Improvements to a comment in lempar.c. No code changes. (check-in: [8000d230] user: drh branch: trunk, size: 33004) | |
|
2017-07-04
| ||
| 12:50 | [10579a61] part of check-in [268a40f4] Fix a problem in the lempar.c Lemon template for YYSTACKDEPTH<=0 introduced by check-in [36e54cd8b1fb37] (check-in: [268a40f4] user: drh branch: trunk, size: 32946) | |
|
2017-06-28
| ||
| 15:01 | [f0dc07c2] part of check-in [36e54cd8] Faster parser stack overflow detection. (check-in: [36e54cd8] user: drh branch: trunk, size: 32920) | |
| 13:47 | [1653b070] part of check-in [b362f0d8] 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: [b362f0d8] user: drh branch: trunk, size: 32819) | |
| 11:56 | [12d9fc3b] part of check-in [c46d94a8] In the lemon-generated parser, automatically promote SHIFTREDUCE actions on nonterminal systems to pure REDUCE actions, for a performance enhancement. (check-in: [c46d94a8] user: drh branch: trunk, size: 32821) | |
|
2017-01-28
| ||
| 20:46 | [db1bdb48] part of check-in [4fe879d4] In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. (check-in: [4fe879d4] user: drh branch: trunk, size: 32649) | |
|
2016-12-06
| ||
| 17:59 | [320d630b] part of check-in [e8247065] In the LEMON parser-generator, fix the stack overflow processing so that it correct invokes the destructor on the top-level of the parse stack. (check-in: [e8247065] user: drh branch: trunk, size: 32271) | |
|
2016-10-04

|
2016-08-10
| ||
| 13:30 | [147e42a5] part of check-in [83622f3f] Improved comments on the lempar.c parser template. Adjust the YY_SHIFT_USE_DFLT constant in the Lemon-generated parser tables so as to guarantee that it is always out of range of the yy_lookahead[] table. (check-in: [83622f3f] user: drh branch: trunk, size: 32245) | |
| 01:43 | [321ebbf1] part of check-in [ba6663be] Performance optimization in the yy_find_shift_action() routine of the Lemon-generated parser. (check-in: [ba6663be] user: drh branch: trunk, size: 32038) | |
|
2016-07-12
| ||
| 19:54 | [57ffa985] part of check-in [3ef93950] Fix the error counter reset in Lemon generated parsers. This has no effect on SQLite. (check-in: [3ef93950] user: drh branch: trunk, size: 32167) | |
|
2016-07-08
| ||
| 19:54 | [77c685a6] part of check-in [e1d8ef31] Another attempt to fix error handling in Lemon. This change is a no-op for SQLite's usage. (check-in: [e1d8ef31] user: drh branch: trunk, size: 32171) | |
|
2016-07-05
| ||
| 16:11 | [072ff998] part of check-in [2683b375] More fixes to Lemon so that it automatically resets its error counter at the end of a parse. (check-in: [2683b375] user: drh branch: trunk, size: 32104) | |
| 12:47 | [f2c88a13] part of check-in [91889fa3] Attempt to reset the error count in the Lemon-generated parser after a parse failure. (check-in: [91889fa3] user: drh branch: trunk, size: 32039) | |
|
2016-06-06
| ||
| 18:17 | [8c4e9d85] part of check-in [3665a2f5] Fix lempar.c so that the shift-reduce optimization works for error processing. This is a Lemon issue only and has no impact on SQLite. (check-in: [3665a2f5] user: drh branch: trunk, size: 31971) | |
| 13:24 | [66a16b5e] part of check-in [45531654] Initialize the yyerrcnt variable in the lemon parser template. This has no effect on SQLite itself. (check-in: [45531654] user: drh branch: trunk, size: 31973) | |
|
2016-05-27
| ||
| 04:10 | [f06b7e98] part of check-in [a9be4c2d] Fix Lemon so that it actually works with -DYYSTACKDEPTH=0. (check-in: [a9be4c2d] user: drh branch: trunk, size: 31912) | |
| 01:07 | [7689ddc4] part of check-in [28d439f8] Fix the Lemon-generated parser so that it compiles with -DYYSTACKDEPTH=0. It does compile now, but there are subtle issues still. (check-in: [28d439f8] user: drh branch: trunk, size: 31613) | |
|
2016-05-24
| ||
| 18:55 | [1f69ad75] part of check-in [41fd46e2] Enhance Lemon and the parser template so that it can once again build parsers that have no unreachable branches. (check-in: [41fd46e2] user: drh branch: trunk, size: 31613) | |
| 00:40 | [8569dd3e] part of check-in [3b28b68e] Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: [3b28b68e] user: drh branch: trunk, size: 31642) | |
|
2016-05-23
| ||
| 21:56 | [872383eb] part of check-in [3c2a7705] Use a pointer to the top of the stack rather than an index into the stack in the Lemon-generated parser template, for about 6.6% parser performance gain. (check-in: [3c2a7705] user: drh branch: trunk, size: 31928) | |
|
2016-03-16
| ||
| 19:45 | [404ea3dc] part of check-in [d5712f21] Enhance Lemon so that it reorders the reduce rules such that rules without actions occur at the end and so that the first rule is number 0. This reduces the size of the jump table on the reduce switch, and helps the parser to run faster. (check-in: [d5712f21] user: drh branch: trunk, size: 31547) | |
|
2016-02-19
| ||
| 13:19 | [d5114c7d] part of check-in [60ad68a9] Omit the unused yyzerominor constant. (check-in: [60ad68a9] user: drh branch: trunk, size: 31577) | |

| 12:34 | [5f626c74] part of check-in [417e7777] More agressive use of /*A-overwrites-X*/ in the parser. Fix an off-by-one error in parser stack overflow detection. (check-in: [417e7777] user: drh branch: parser-performance, size: 31722) | |
| 01:46 | [c7dde8fa] part of check-in [ef95a7d6] Further improvements to the Lemon-generated code for yy_reduce(). (check-in: [ef95a7d6] user: drh branch: parser-performance, size: 31716) | |
| 01:18 | [08bbb0fb] part of check-in [4bb94c7c] In Lemon, add the ability for the left-most RHS label to be the same as the LHS label, causing the LHS values to be written directly into the stack. (check-in: [4bb94c7c] user: drh branch: parser-performance, size: 31752) | |

| 15:06 | [4ff2afb0] part of check-in [0557a179] Avoid recursion in the yy_find_shift_action() routine of the Lemon-generated parser, so that routine can be inlined, for a size reduction and performance increase. (check-in: [0557a179] user: drh branch: trunk, size: 29290) | |
| 14:11 | [5ea7cad7] part of check-in [9748c48a] Size reduction and performance improvement in the stack-popping logic of the Lemon-generated parser. (check-in: [9748c48a] user: drh branch: trunk, size: 28900) | |

2009-06-12
| ||
| 13:53 | [2ed70b3f] part of check-in [fe9c9177] The lemon parser generator now inserts yytestcase() macros on reduce action and on each destructor, to verify that all have been executed. yytestcase() is a no-op by default but can be set to something more useful inside of %include.
