Special sqlite_stat1 Handling

+** +** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to +** some of the rules above. In SQLite, the schema of sqlite_stat1 is: +** 
+**        CREATE TABLE sqlite_stat1(tbl,idx,stat)  
+**
+** +** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are +** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes +** are recorded for rows for which (idx IS NULL) is true. However, for such +** rows a zero-length blob (SQL value X'') is stored in the changeset or +** patchset instead of a NULL value. This allows such changesets to be +** manipulated by legacy implementations of sqlite3changeset_invert(), +** concat() and similar. +** +** The sqlite3changeset_apply() function automatically converts the +** zero-length blob back to a NULL value when updating the sqlite_stat1 +** table. However, if the application calls sqlite3changeset_new(), +** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset +** iterator directly (including on a changeset iterator passed to a +** conflict-handler callback) then the X'' value is returned. The application +** must translate X'' to NULL itself if required. +** +** Legacy (older than 3.22.0) versions of the sessions module cannot capture +** changes made to the sqlite_stat1 table. Legacy versions of the +** sqlite3changeset_apply() function silently ignore any modifications to the +** sqlite_stat1 table that are part of a changeset or patchset. */ SQLITE_API int

Special sqlite_stat1 Handling

+** +** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to +** some of the rules above. In SQLite, the schema of sqlite_stat1 is: +** 
+**        CREATE TABLE sqlite_stat1(tbl,idx,stat)  
+**
+** +** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are +** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes +** are recorded for rows for which (idx IS NULL) is true. However, for such +** rows a zero-length blob (SQL value X'') is stored in the changeset or +** patchset instead of a NULL value. This allows such changesets to be +** manipulated by legacy implementations of sqlite3changeset_invert(), +** concat() and similar. +** +** The sqlite3changeset_apply() function automatically converts the +** zero-length blob back to a NULL value when updating the sqlite_stat1 +** table. However, if the application calls sqlite3changeset_new(), +** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset +** iterator directly (including on a changeset iterator passed to a +** conflict-handler callback) then the X'' value is returned. The application +** must translate X'' to NULL itself if required. +** +** Legacy (older than 3.22.0) versions of the sessions module cannot capture +** changes made to the sqlite_stat1 table. Legacy versions of the +** sqlite3changeset_apply() function silently ignore any modifications to the +** sqlite_stat1 table that are part of a changeset or patchset. */ SQLITE_API int sqlite3session_attach( sqlite3_session *pSession, /* Session object */ diff --git a/sqlite3ext.h b/sqlite3ext.h index d5fd905..4c65bec 100644 --- a/sqlite3ext.h +++ b/sqlite3ext.h @@ -293,6 +293,9 @@ struct sqlite3_api_routines { int (*bind_pointer)(sqlite3_stmt*,int,void*,const char*,void(*)(void*)); void (*result_pointer)(sqlite3_context*,void*,const char*,void(*)(void*)); void *(*value_pointer)(sqlite3_value*,const char*); + int (*vtab_nochange)(sqlite3_context*); + int (*value_nochange)(sqlite3_value*); + const char *(*vtab_collation)(sqlite3_index_info*,int); }; /* @@ -559,6 +562,10 @@ typedef int (*sqlite3_loadext_entry)( #define sqlite3_bind_pointer sqlite3_api->bind_pointer #define sqlite3_result_pointer sqlite3_api->result_pointer #define sqlite3_value_pointer sqlite3_api->value_pointer +/* Version 3.22.0 and later */ +#define sqlite3_vtab_nochange sqlite3_api->vtab_nochange +#define sqlite3_value_nochange sqltie3_api->value_nochange +#define sqlite3_vtab_collation sqltie3_api->vtab_collation #endif /* !defined(SQLITE_CORE) && !defined(SQLITE_OMIT_LOAD_EXTENSION) */ #if !defined(SQLITE_CORE) && !defined(SQLITE_OMIT_LOAD_EXTENSION) diff --git a/tool/upgrade.go b/tool/upgrade.go index 94ed39d..275f915 100644 --- a/tool/upgrade.go +++ b/tool/upgrade.go @@ -29,7 +29,7 @@ func main() { var url string doc.Find("a").Each(func(_ int, s *goquery.Selection) { if url == "" && strings.HasPrefix(s.Text(), "sqlite-amalgamation-") { - url = "https://www.sqlite.org/2017/" + s.Text() + url = "https://www.sqlite.org/2018/" + s.Text() } }) if url == "" {
