    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.

    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.

This in turn can bring high overhead for communicating on "done", which ultimately can result in full context switch: if the spawned goroutine had chance to run, already checked done and ctx to be not ready, and went into sleep via wait on futex - showing as something like below in strace for one read query (note futex calls): 27867 00:38:39.782146 stat(".../neo.sqlite-journal", 0x7f83809c4a20) = -1 ENOENT (No such file or directory) 27867 00:38:39.782165 pread64(3, "\0\0\0\33\0\0\10\235\0\0\10]\0\0\0\27", 16, 24) = 16 27871 00:38:39.782179 <... pselect6 resumed> ) = 0 (Timeout) 27868 00:38:39.782187 <... pselect6 resumed> ) = 0 (Timeout) 27871 00:38:39.782193 futex(0xc4200f8538, FUTEX_WAIT, 0, NULL 27868 00:38:39.782199 futex(0xc420013138, FUTEX_WAIT, 0, NULL 27867 00:38:39.782205 stat(".../neo.sqlite-wal", 0x7f83809c4a20) = -1 ENOENT (No such file or directory) 27867 00:38:39.782224 fstat(3, {st_mode=S_IFREG|0644, st_size=9031680, ...}) = 0 27867 00:38:39.782247 futex(0xc420013138, FUTEX_WAKE, 1 27868 00:38:39.782259 <... futex resumed> ) = 0 27867 00:38:39.782265 <... futex resumed> ) = 1 27868 00:38:39.782270 pselect6(0, NULL, NULL, NULL, {tv_sec=0, tv_nsec=3000}, NULL 27867 00:38:39.782279 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0 27867 00:38:39.782315 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1}) = 0 27868 00:38:39.782336 <... pselect6 resumed> ) = 0 (Timeout) 27867 00:38:39.782342 fcntl(3, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=1073741826, l_len=510} 27868 00:38:39.782348 futex(0xc4200f8538, FUTEX_WAKE, 1 27867 00:38:39.782355 <... fcntl resumed> ) = 0 27871 00:38:39.782360 <... futex resumed> ) = 0 27868 00:38:39.782367 <... futex resumed> ) = 1 27871 00:38:39.782372 futex(0xc4200f8138, FUTEX_WAKE, 1 27868 00:38:39.782377 pselect6(0, NULL, NULL, NULL, {tv_sec=0, tv_nsec=3000}, NULL 27871 00:38:39.782384 <... futex resumed> ) = 1 27870 00:38:39.782389 <... futex resumed> ) = 0 27867 00:38:39.782394 fcntl(3, F_SETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=1073741824, l_len=1} 27870 00:38:39.782400 pselect6(0, NULL, NULL, NULL, {tv_sec=0, tv_nsec=3000}, NULL 27867 00:38:39.782408 <... fcntl resumed> ) = 0 Below link shows that go scheduler itself might be significantly improved for cases when there are several Cgo calls made for a request in a server: https://github.com/golang/go/issues/21827#issuecomment-329092317 in particular CGo-4 case should be closely related to this sqlite3 go package, because for one query many CGo calls are made to SQLite. However until there are proper scheduler fixes, let's make what could be made to improve time to do queries: If we know that the context under which a query is executed will never be canceled - we know we can safely skip spawning the interrupt goroutine and this was avoid ping-pong on done in between different OS threads.

    • If there have been no REPLACE resolutions on a key, then +** the local changeset is rebased according to the most recent +** of the OMIT resolutions. +**
