<h2>SQLite Release 3.31.1 On 2020-01-27</h2><p><b>Changes in version 3.31.0 (2020-01-22):</b></p>
|
|
<p><ol class='lessindent'>
|
|
<li value='1'>Add support for <a href="../gencol.html">generated columns</a>.
|
|
<li>Add the <a href="../c3ref/hard_heap_limit64.html">sqlite3_hard_heap_limit64()</a> interface and the corresponding
|
|
<a href="../pragma.html#pragma_hard_heap_limit">PRAGMA hard_heap_limit</a> command.
|
|
<li>Enhance the <a href="../pragma.html#pragma_function_list">function_list pragma</a> to show the number of arguments on each
|
|
function, the type of function (scalar, aggregate, window), and the function
|
|
property flags <a href="../c3ref/c_deterministic.html#sqlitedeterministic">SQLITE_DETERMINISTIC</a>, <a href="../c3ref/c_deterministic.html#sqlitedirectonly">SQLITE_DIRECTONLY</a>,
|
|
<a href="../c3ref/c_deterministic.html#sqliteinnocuous">SQLITE_INNOCUOUS</a>, and/or <a href="../c3ref/c_deterministic.html#sqlitesubtype">SQLITE_SUBTYPE</a>.
|
|
<li>Add the <a href="../dbstat.html#dbstatagg">aggregated mode</a> feature to the
|
|
<a href="../dbstat.html">DBSTAT virtual table</a>.
|
|
<li>Add the <a href="../c3ref/open.html#opennofollow">SQLITE_OPEN_NOFOLLOW</a> option to <a href="../c3ref/open.html">sqlite3_open_v2()</a> that
|
|
prevents SQLite from opening symbolic links.
|
|
<li>Added the "#-N" array notation for <a href="../json1.html#jsonpath">JSON function path arguments</a>.
|
|
<li>Added the <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigtrustedschema">SQLITE_DBCONFIG_TRUSTED_SCHEMA</a> connection setting which is
|
|
also controllable via the new <a href="../pragma.html#pragma_trusted_schema">trusted_schema pragma</a> and at compile-time
|
|
using the <a href="../compile.html#trusted_schema">-DSQLITE_TRUSTED_SCHEMA</a> compile-time option.
|
|
<li>Added APIs <a href="../c3ref/filename_database.html">sqlite3_filename_database()</a>, <a href="../c3ref/filename_database.html">sqlite3_filename_journal()</a>, and
|
|
<a href="../c3ref/filename_database.html">sqlite3_filename_wal()</a> which are useful for specialized extensions.
|
|
<li>Add the <a href="../c3ref/uri_boolean.html">sqlite3_uri_key()</a> interface.
|
|
<li>Upgraded the <a href="../c3ref/uri_boolean.html">sqlite3_uri_parameter()</a> function so that it works with the
|
|
rollback journal or WAL filename in addition to the database filename.
|
|
<li>Provide the ability to tag <a href="../appfunc.html">application-defined SQL functions</a> with
|
|
new properties <a href="../c3ref/c_deterministic.html#sqliteinnocuous">SQLITE_INNOCUOUS</a> or <a href="../c3ref/c_deterministic.html#sqlitedirectonly">SQLITE_DIRECTONLY</a>.
|
|
<li>Add new verbs to <a href="../c3ref/vtab_config.html">sqlite3_vtab_config()</a> so that the <a href="../vtab.html#xconnect">xConnect</a> method
|
|
of virtual tables can declare the virtual table as
|
|
<a href="../c3ref/c_vtab_constraint_support.html#sqlitevtabinnocuous">SQLITE_VTAB_INNOCUOUS</a> or <a href="../c3ref/c_vtab_constraint_support.html#sqlitevtabdirectonly">SQLITE_VTAB_DIRECTONLY</a>.
|
|
<li>Faster response to <a href="../c3ref/interrupt.html">sqlite3_interrupt()</a>.
|
|
<li>Added the <a href="https://sqlite.org/src/file/ext/misc/uuid.c">uuid.c</a> extension module
|
|
implementing functions for processing RFC-4122 UUIDs.
|
|
<li>The <a href="../malloc.html#lookaside">lookaside memory allocator</a> is enhanced to support two separate memory
|
|
pools with different sized allocations in each pool. This allows more memory
|
|
allocations to be covered by lookaside while at the same time reducing the
|
|
heap memory usage to 48KB per connection, down from 120KB.
|
|
<li>The <a href="../pragma.html#pragma_legacy_file_format">legacy_file_format pragma</a> is deactivated. It is now a no-op. In its place,
|
|
the <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfiglegacyfileformat">SQLITE_DBCONFIG_LEGACY_FILE_FORMAT</a> option to <a href="../c3ref/db_config.html">sqlite3_db_config()</a> is
|
|
provided. The legacy_file_format pragma is deactivated because (1) it is
|
|
rarely useful and (2) it is incompatible with <a href="../lang_vacuum.html">VACUUM</a> in schemas that have
|
|
tables with both generated columns and descending indexes.

<p><b>Additional changes in version 3.31.1:</b></p>
|
|
<p><ol class='lessindent'>
|
|
<li value='17'> Revert the data layout for an internal-use-only SQLite data structure.
|
|
Applications that use SQLite should never reference internal SQLite
|
|
data structures, but some do anyhow, and a change to one such
|
|
data structure in 3.30.0 broke a popular and widely-deployed
|
|
application. Reverting that change in SQLite, at least temporarily,
|
|
gives developers of misbehaving applications time to fix their code.
|
|
<li> Fix a typos in the sqlite3ext.h header file that prevented the
|
|
<a href="../c3ref/stmt_isexplain.html">sqlite3_stmt_isexplain()</a> and <a href="../c3ref/value_blob.html">sqlite3_value_frombind()</a> interfaces
|
|
from being called from <a href="../loadext.html">run-time loadable extensions</a>.
