quantities of things SQLite can process. This change might cause

compatibility problems for

applications that use SQLite in the extreme, which is why the current

release is 3.4.0 instead of 3.3.18.</li>

in 3.3.13 that could cause a segfault when the IN operator

the IN operator contains a NULL.</li>

of underlying media: sqlite3OsSectorSize().</li>
|
|
<li>A new algorithm for statements of the form

INSERT INTO <i>table1</i> SELECT * FROM <i>table2</i>

is faster and reduces fragmentation. VACUUM uses statements of

this form and thus runs faster and defragments better.</li>

<li>Performance enhancements through reductions in disk I/O:

rollback journal.</li>

<li>Do not read in the (meaningless) content of

pages extracted from the freelist.</li>

<li>Do not flush the page cache (and thus avoiding
|
|
a cache refill) unless another process changes the underlying
|
|
database file.</li>

|
|
a transaction in exclusive access mode, or when committing the TEMP
|
|
database.</li>

|
<a href="pragma.html#pragma_locking_mode">
|
|
"PRAGMA locking_mode=EXCLUSIVE"</a></li>
|
|
<li>Use heap space instead of stack space for large buffers in the
|
|
pager - useful on embedded platforms with stack-space
|
|
limitations.</li>

<li>Add a makefile target "sqlite3.c" that builds an amalgamation containing
|
|
the core SQLite library C code in a single file.</li>

|
|
with GCC option "-fstrict-aliasing".</li>

This function is designed for use in test scripts to verify that

useful purpose, as far as I know.</li>

<li>Added the <B>COPY</b> command patterned after

<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
