I have a question regarding the API documention at
http://sqlite.org/c3ref/value_blob.html, which states:
"... the pointer returned from sqlite3_value_blob(), .. can be invalidated
by a subsequent call to sqlite3_value_bytes(), ..."
Is that statement still true? I ask because I notice that the source of
many of the extensions in 'sqlite/ext' seem to violate that advice.
I first noticed this when I was recently working on fileio.c (e.g. line 73
vs 77), but grepping through the source I find many other cases where the
pointer is retrieved via *_blob() or *.text() BEFORE invoking
sqlite3_value_bytes(). E.g these source and line numbers:
fts2_tokenizer.c:71, 72
fts3_expr.c:1248, 1249
fts3_tokenizer.c:78, 79
fts3_tokenize_vtab.c:347, 348
fts3_write.c:5290, 5291
fts5_index.c:6270, 6271
fts5_storage.c:735, 736
fts5_tcl.c:547
fts5_test_tok.c:375, 376
fts5_vocab.c:607, 608; 612, 613; 616, 617
(I stopped grepping at this point; this list is not comprehensive).
Anyway, just wondered if the api documentation's advice is maybe out-of-date
with current reality. Thoughts/comments?
Cheers!
