Dmitry Voropaev ab01d18474 gh-142083: Document the 'w' type code in the array.array docstring (#158040) 
Add a test asserting that the table lists exactly the supported type
codes and that the minimum size it gives for each of them is one the
implementation really meets.

Sergey B Kirpichev c0bc6fad25 gh-156865: Correctly detect overflows for array's "e", "f" and "Zf" type codes (#156869) 2026-09-18 17:16:57 +02:00
PhysicistJohnandVictor Stinner 46c355fabf gh-154566: Fix array.byteswap() corrupting 'Zd' arrays with more than one element (#154567) 
Fix array.array.byteswap() corrupting data for 'Zd' (complex
double) arrays with more than one element: the 16-byte item loop advanced
the buffer pointer by only 8 bytes per iteration, causing items after the
first to be scrambled.

PhysicistJohn f3be08aa6f gh-154568: Fix array unpickling of little-endian float16 (#154569) 
Fix array._array_reconstructor() ignoring requested byte order for float16.

The slow-path decoder for IEEE_754_FLOAT16_LE/BE computed the
byte-order flag by comparing mformat_code against IEEE_754_FLOAT_LE
(the 32-bit float constant) instead of IEEE_754_FLOAT16_LE. Since the
float16 mformat codes are never equal to that constant, the comparison
was always false, so the decoder always treated input as big-endian
regardless of what was requested.

Adds a regression test.

Zackery SpytzandMartin Panter 14514d9084 bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375) 
The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.
