I/O error finding a temporary directory

SQLITE_IOERR_GETTEMPPATH (6410) is returned when SQLite cannot determine a writable temporary directory for creating temporary files used during large sorts and intermediate results.

1. 1TMPDIR / TEMP / TMP environment variables point to a non-existent or non-writable directory.
2. 2All candidate temporary directories are full or inaccessible.
3. 3Chroot or sandboxed environment with no accessible temp path.

Queries requiring temporary storage (large sorts, CREATE INDEX, etc.) when no temp dir is available.

import os, sqlite3
os.environ['TMPDIR'] = '/nonexistent'
conn = sqlite3.connect(':memory:')
# Large sort requiring temp file may raise SQLITE_IOERR_GETTEMPPATH
