From 796a4b74823b721c72de07e45718f05e78e1565d Mon Sep 17 00:00:00 2001 From: David Robertson Date: Tue, 31 Jan 2023 10:33:07 +0000 Subject: Prefer `type(x) is int` to `isinstance(x, int)` (#14945) * Perfer `type(x) is int` to `isinstance(x, int)` This covered all additional instances I could see where `x` was user-controlled. The remaining cases are ``` $ rg -s 'isinstance.*[^_]int' tests/replication/_base.py 576: if isinstance(obj, int): synapse/util/caches/stream_change_cache.py 136: assert isinstance(stream_pos, int) 214: assert isinstance(stream_pos, int) 246: assert isinstance(stream_pos, int) 267: assert isinstance(stream_pos, int) synapse/replication/tcp/external_cache.py 133: if isinstance(result, int): synapse/metrics/__init__.py 100: if isinstance(calls, (int, float)): synapse/handlers/appservice.py 262: assert isinstance(new_token, int) synapse/config/_util.py 62: if isinstance(p, int): ``` which cover metrics, logic related to `jsonschema`, and replication and data streams. AFAICS these are all internal to Synapse * Changelog --- synapse/rest/media/v1/oembed.py | 2 +- synapse/rest/media/v1/thumbnailer.py | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'synapse/rest/media') diff --git a/synapse/rest/media/v1/oembed.py b/synapse/rest/media/v1/oembed.py index a3738a6250..7592aa5d47 100644 --- a/synapse/rest/media/v1/oembed.py +++ b/synapse/rest/media/v1/oembed.py @@ -200,7 +200,7 @@ class OEmbedProvider: calc_description_and_urls(open_graph_response, oembed["html"]) for size in ("width", "height"): val = oembed.get(size) - if val is not None and isinstance(val, int): + if type(val) is int: open_graph_response[f"og:video:{size}"] = val elif oembed_type == "link": diff --git a/synapse/rest/media/v1/thumbnailer.py b/synapse/rest/media/v1/thumbnailer.py index a48a4de92a..9480cc5763 100644 --- a/synapse/rest/media/v1/thumbnailer.py +++ b/synapse/rest/media/v1/thumbnailer.py @@ -77,7 +77,7 @@ class Thumbnailer: image_exif = self.image._getexif() # type: ignore if image_exif is not None: image_orientation = image_exif.get(EXIF_ORIENTATION_TAG) - assert isinstance(image_orientation, int) + assert type(image_orientation) is int self.transpose_method = EXIF_TRANSPOSE_MAPPINGS.get(image_orientation) except Exception as e: # A lot of parsing errors can happen when parsing EXIF -- cgit 1.4.1
