In `@crates/stdlib/src/_sqlite3.rs`:
- Around line 1527-1537: In both setconfig and getconfig, acquire the database
with db_lock(vm)? before validating op via is_int_dbconfig(op), so closed or
uninitialized connections report the connection-state error first while
preserving the existing unknown-op ValueError for valid connections.
- Around line 164-171: Complete the SQLite dbconfig handling around the existing
exports and is_int_dbconfig validation: add STMT_SCANSTATUS, REVERSE_SCANORDER,
ENABLE_ATTACH_CREATE, ENABLE_ATTACH_WRITE, and ENABLE_COMMENTS to the exports
and boolean-accepted options; export MAINDBNAME, LOOKASIDE, and FP_DIGITS; and
add their distinct argument-contract validation before the boolean path accepts
options.

libsqlite3-sys 0.38 bundled sqlite3.h SQLITE_DBCONFIG_STMT_SCANSTATUS SQLITE_DBCONFIG_REVERSE_SCANORDER SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE SQLITE_DBCONFIG_ENABLE_ATTACH_WRITE SQLITE_DBCONFIG_ENABLE_COMMENTS
💡 Result:
The constants mentioned—SQLITE_DBCONFIG_STMT_SCANSTATUS, SQLITE_DBCONFIG_REVERSE_SCANORDER, SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE, SQLITE_DBCONFIG_ENABLE_ATTACH_WRITE, and SQLITE_DBCONFIG_ENABLE_COMMENTS—are configuration options for the sqlite3_db_config C API function [1][2]. These options were introduced in SQLite 3.42.0 (released May 16, 2023) [3][4]. Regarding their usage in libsqlite3-sys 0.38.x: - libsqlite3-sys 0.38.x includes bundled versions of SQLite [5]. As of libsqlite3-sys 0.38.1, the bundled version is SQLite 3.53.2 [5], which is significantly newer than the 3.42.0 version where these options were first introduced [3]. - Consequently, these constants are available in the bundled sqlite3.h and the corresponding Rust bindings provided by libsqlite3-sys 0.38.x [6][7]. Summary of the options: - SQLITE_DBCONFIG_STMT_SCANSTATUS: Enables or disables the collection of run-time performance statistics for a database connection (requires SQLITE_ENABLE_STMT_SCANSTATUS build) [1][8]. - SQLITE_DBCONFIG_REVERSE_SCANORDER: Changes the default scan order of tables and indexes, equivalent to PRAGMA reverse_unordered_selects [9][2]. - SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE, SQLITE_DBCONFIG_ENABLE_ATTACH_WRITE, and SQLITE_DBCONFIG_ENABLE_COMMENTS: These are specific configuration options added to control attachment and comment-related behaviors, also available as of SQLite 3.42.0 [4]. If you are using the bundled feature of libsqlite3-sys, these constants are fully supported and exposed through the generated bindings [5][6].

site:docs.rs/crate/libsqlite3-sys/0.38.0/source/sqlite3/sqlite3.h SQLITE_DBCONFIG
💡 Result:
SQLITE_DBCONFIG refers to a set of constant integer values used as configuration verbs for the sqlite3_db_config interface in SQLite [1][2][3]. This interface allows applications to modify settings for a specific database connection, rather than applying global configuration changes [3]. The sqlite3_db_config function is defined as follows [3]: int sqlite3_db_config(sqlite3 *db, int op,...); The second argument (op) is one of the SQLITE_DBCONFIG constants, and subsequent arguments vary based on the chosen option [3]. Most of these configuration options follow a standard format where they take two additional arguments: an integer to enable (1) or disable (0) a feature, and a pointer to an integer where the new status is stored [1][4]. However, some options, such as SQLITE_DBCONFIG_MAINDBNAME and SQLITE_DBCONFIG_LOOKASIDE, use unique argument formats and require specific handling [1][4]. Commonly used SQLITE_DBCONFIG options include: SQLITE_DBCONFIG_MAINDBNAME: Used to change the name of the main database schema. It requires a pointer to a constant UTF8 string [1][2]. SQLITE_DBCONFIG_LOOKASIDE: Used to adjust lookaside memory configuration for an individual connection [5][4]. SQLITE_DBCONFIG_ENABLE_FKEY: Used to enable or disable foreign key constraints [4]. SQLITE_DBCONFIG_RESET_DATABASE: Used in conjunction with a VACUUM command to reset a database file to an empty state [2]. Applications should always check the return code of sqlite3_db_config to verify if a configuration call was successful, as unsupported or discontinued options will return a non-zero error code [1][2]. New configuration options may be added in future versions of SQLite [1].

SQLite 3.53.2 sqlite3.h SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE SQLITE_DBCONFIG_ENABLE_COMMENTS SQLITE_DBCONFIG_FP_DIGITS
💡 Result:
The constants SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE (1020), SQLITE_DBCONFIG_ENABLE_COMMENTS (1022), and SQLITE_DBCONFIG_FP_DIGITS (1023) are database connection configuration options used with the sqlite3_db_config interface in SQLite [1][2]. SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE (1020) This option controls whether the ATTACH DATABASE SQL command is permitted to create a new database file if the specified file does not already exist [1]. It is enabled by default [1]. Applications can use this setting to disable automatic file creation to prevent unauthorized or accidental file generation, which is particularly relevant in security-sensitive contexts where untrusted paths might be used [1][3]. SQLITE_DBCONFIG_ENABLE_COMMENTS (1022) This option enables or disables the ability to include comments in SQL input text [4]. Introduced in version 3.49.0, it is enabled by default [4][5]. A later refinement ensures that comments are still permitted when reading a schema from an existing sqlite_schema table, even if they are blocked in new SQL statements [5]. SQLITE_DBCONFIG_FP_DIGITS (1023) This setting specifies the number of significant digits SQLite preserves when converting IEEE 754 floating-point numbers into text [2]. The default value was changed from 15 to 17 in version 3.52.0 (released March 2026) [6][2]. This change supports an enhanced rounding algorithm that improves the precision of floating-point representations [6]. The valid range for this setting is typically between 3 and 23 [2]. These options are defined in the sqlite3.h header file [1][7]. They are configured by passing the constant to sqlite3_db_config(db, op,...), where the exact number and type of subsequent arguments vary by option [1][8].

💡 Result:
These constants are configuration verbs used with the sqlite3_db_config interface to modify specific behaviors of a SQLite database connection [1][2]. SQLITE_DBCONFIG_FP_DIGITS This option sets or retrieves the number of significant digits preserved when converting IEEE 754 floating-point numbers to text [2]. It accepts an integer argument between 3 and 23 [2]. The default value is 17 (as of SQLite version 3.52.0), having been increased from 15 in earlier versions [2][3][4]. This setting allows applications to balance precision and performance, as higher digit counts may trigger additional computational steps to ensure binary-to-text-to-binary round-trip consistency [3]. SQLITE_DBCONFIG_REVERSE_SCANORDER This option enables or disables the reversal of the scan order for database queries [5]. When enabled, it forces table scans to proceed in reverse order [5]. This is primarily used as a diagnostic tool to detect ambiguous queries; by running a query both with and without this option enabled, developers can identify if a query returns different results based on the scan order, which indicates an unordered result set [5]. It is the programmatic equivalent of the PRAGMA reverse_unordered_selects statement [5]. SQLITE_DBCONFIG_ENABLE_ATTACH_WRITE This option controls the ability to write to attached databases [2][6]. When configured, it allows or restricts write operations on databases that have been attached to the main database connection using the ATTACH command [2]. It is part of a suite of security and fine-grained configuration options that allow applications to restrict the capabilities of a specific database connection [2].
