# NOTES ON RECOVERING FROM A MALLOC FAILURE
|
|
#
|
|
# The tests in this file test the behaviours described in the following
|
|
# paragraphs. These tests test the behaviour of the system when malloc() fails
|
|
# inside of a call to _prepare(), _step(), _finalize() or _reset(). The
|
|
# handling of malloc() failures within ancillary procedures is tested
|
|
# elsewhere.
|
|
#
|
|
# Overview:
|
|
#
|
|
# Executing a statement is done in three stages (prepare, step and finalize). A
|
|
# malloc() failure may occur within any stage. If a memory allocation fails
|
|
# during statement preparation, no statement handle is returned. From the users
|
|
# point of view the system state is as if _prepare() had never been called.
|
|
#
|
|
# If the memory allocation fails during the _step() or _finalize() calls, then
|
|
# the database may be left in one of two states (after finalize() has been
|
|
# called):
|
|
#
|
|
# * As if the neither _step() nor _finalize() had ever been called on
|
|
# the statement handle (i.e. any changes made by the statement are
|
|
# rolled back).
|
|
# * The current transaction may be rolled back. In this case a hot-journal
|
|
# may or may not actually be present in the filesystem.
|
|
#
|
|
# The caller can tell the difference between these two scenarios by invoking
|
|
# _get_autocommit().
|
|
#
|
|
#
|
|
# Handling of sqlite3_reset():
|
|
#
|
|
# If a malloc() fails while executing an sqlite3_reset() call, this is handled
|
|
# in the same way as a failure within _finalize(). The statement handle
|
|
# is not deleted and must be passed to _finalize() for resource deallocation.
|
|
# Attempting to _step() or _reset() the statement after a failed _reset() will
|
|
# always return SQLITE_NOMEM.
|
|
#
|
|
#
|
|
# Other active SQL statements:
|
|
#
|
|
# The effect of a malloc failure on concurrently executing SQL statements,
|
|
# particularly when the statement is executing with READ_UNCOMMITTED set and
|
|
# the malloc() failure mandates statement rollback only. Currently, if
|
|
# transaction rollback is required, all other vdbe's are aborted.
|
|
#
|
|
# Non-transient mallocs in btree.c:
|
|
# * The Btree structure itself
|
|
# * Each BtCursor structure
|
|
#
|
|
# Mallocs in pager.c:
|
|
# readMasterJournal() - Space to read the master journal name
|
|
# pager_delmaster() - Space for the entire master journal file
|
|
#
|
|
# sqlite3pager_open() - The pager structure itself
|
|
# sqlite3_pagerget() - Space for a new page
|
|
# pager_open_journal() - Pager.aInJournal[] bitmap
|
|
# sqlite3pager_write() - For in-memory databases only: history page and
|
|
# statement history page.
|
|
# pager_stmt_begin() - Pager.aInStmt[] bitmap
|
|
#
|
|
# None of the above are a huge problem. The most troublesome failures are the
|
|
# transient malloc() calls in btree.c, which can occur during the tree-balance
|
|
# operation. This means the tree being balanced will be internally inconsistent
|
|
# after the malloc() fails. To avoid the corrupt tree being read by a
|
|
# READ_UNCOMMITTED query, we have to make sure the transaction or statement
|
|
# rollback occurs before sqlite3_step() returns, not during a subsequent
|
|
# sqlite3_finalize().

# NOTES ON TEST IMPLEMENTATION
|
|
#
|
|
# The tests in this file are implemented differently from those in other
|
|
# files. Instead, tests are specified using three primitives: SQL, PREP and
|
|
# TEST. Each primitive has a single argument. Primitives are processed in
|
|
# the order they are specified in the file.
|
|
#
|
|
# A TEST primitive specifies a TCL script as its argument. When a TEST
|
|
# directive is encountered the Tcl script is evaluated. Usually, this Tcl
|
|
# script contains one or more calls to [do_test].
|
|
#
|
|
# A PREP primitive specifies an SQL script as its argument. When a PREP
|
|
# directive is encountered the SQL is evaluated using database connection
|
|
# [db].
|
|
#
|
|
# The SQL primitives are where the action happens. An SQL primitive must
|
|
# contain a single, valid SQL statement as its argument. When an SQL
|
|
# primitive is encountered, it is evaluated one or more times to test the
|
|
# behaviour of the system when malloc() fails during preparation or
|
|
# execution of said statement. The Nth time the statement is executed,
|
|
# the Nth malloc is said to fail. The statement is executed until it
|
|
# succeeds, i.e. (M+1) times, where M is the number of mallocs() required
|
|
# to prepare and execute the statement.
|
|
#
|
|
# Each time an SQL statement fails, the driver program (see proc [run_test]
|
|
# below) figures out if a transaction has been automatically rolled back.
|
|
# If not, it executes any TEST block immediately proceeding the SQL
|
|
# statement, then reexecutes the SQL statement with the next value of N.
|
|
#
|
|
# If a transaction has been automatically rolled back, then the driver
|
|
# program executes all the SQL specified as part of SQL or PREP primitives
|
|
# between the current SQL statement and the most recent "BEGIN". Any
|
|
# TEST block immediately proceeding the SQL statement is evaluated, and
|
|
# then the SQL statement reexecuted with the incremented N value.
|
|
#
|
|
# That make any sense? If not, read the code in [run_test] and it might.
|
|
#
|
|
# Extra restriction imposed by the implementation:
|
|
#
|
|
# * If a PREP block starts a transaction, it must finish it.
|
|
# * A PREP block may not close a transaction it did not start.
|
|

# These procs are used to build up a "program" in global variable
