Thread safety: Reading a single element from a "list" is *atomic*:
|
||||
|
||||
lst[i] # list.__getitem__
|
||||
|
||||
The following methods traverse the list and use *atomic* reads of each
|
||||
item to perform their function. That means that they may return
|
||||
results affected by concurrent modifications:
|
||||
|
||||
item in lst
|
||||
lst.index(item)
|
||||
lst.count(item)
|
||||
|
||||
All of the above methods/operations are also lock-free. They do not
|
||||
block concurrent modifications. Other operations that hold a lock will
|
||||
not block these from observing intermediate states.All other
|
||||
operations from here on block using the per-object lock.Writing a
|
||||
single item via "lst[i] = x" is safe to call from multiple threads and
|
||||
will not corrupt the list.The following operations return new objects
|
||||
and appear *atomic* to other threads:
|
||||
|
||||
lst1 + lst2 # concatenates two lists into a new list
|
||||
x * lst # repeats lst x times into a new list
|
||||
lst.copy() # returns a shallow copy of the list
|
||||
|
||||
Methods that only operate on a single elements with no shifting
|
||||
required are *atomic*:
|
||||
|
||||
lst.append(x) # append to the end of the list, no shifting required
|
||||
lst.pop() # pop element from the end of the list, no shifting required
|
||||
|
||||
The "clear()" method is also *atomic*. Other threads cannot observe
|
||||
elements being removed.The "sort()" method is not *atomic*. Other
|
||||
threads cannot observe intermediate states during sorting, but the
|
||||
list appears empty for the duration of the sort.The following
|
||||
operations may allow lock-free operations to observe intermediate
|
||||
states since they modify multiple elements in place:
|
||||
|
||||
lst.insert(idx, item) # shifts elements
|
||||
lst.pop(idx) # idx not at the end of the list, shifts elements
|
||||
lst *= x # copies elements in place
|
||||
|
||||
The "remove()" method may allow concurrent modifications since element
|
||||
comparison may execute arbitrary Python code (via
|
||||
"__eq__()")."extend()" is safe to call from multiple threads.
|
||||
However, its guarantees depend on the iterable passed to it. If it is
|
||||
a "list", a "tuple", a "set", a "frozenset", a "dict" or a dictionary
|
||||
view object (but not their subclasses), the "extend" operation is safe
|
||||
from concurrent modifications to the iterable. Otherwise, an iterator
|
||||
is created which can be concurrently modified by another thread. The
|
||||
same applies to inplace concatenation of a list with other iterables
|
||||
when using "lst += iterable".Similarly, assigning to a list slice with
|
||||
"lst[i:j] = iterable" is safe to call from multiple threads, but
|
||||
"iterable" is only locked when it is also a "list" (but not its
|
||||
subclasses).Operations that involve multiple accesses, as well as
|
||||
iteration, are never atomic. For example:
|
||||
|
||||
# NOT atomic: read-modify-write
|
||||
lst[i] = lst[i] + 1
|
||||
|
||||
# NOT atomic: check-then-act
|
||||
if lst:
|
||||
item = lst.pop()
|
||||
|
||||
# NOT thread-safe: iteration while modifying
|
||||
for item in lst:
|
||||
process(item) # another thread may modify lst
|
||||
|
||||
Consider external synchronization when sharing "list" instances across
|
||||
threads. See Python support for free threading for more information.

Fix a free-threaded GC performance regression. If there are many untracked
|
||||
tuples, the GC will run too often, resulting in poor performance. The fix
|
||||
is to include untracked tuples in the "long lived" object count. The number
|
||||
of frozen objects is also now included since the free-threaded GC must
|
||||
scan those too.
