+fixServiceWorker:
+
+There is exactly one situation where I know this is definitely needed, though
+browsers I think could revoke the service worker at any time, so it is good to
+have an automated way to fix this. Also, this may be useful if we upgrade the
+service worker and add a new URL endpoint, since this will get triggered.
+
+1. Open python-wasm using a service worker on an iphone or ipad in safari.
+
+2. Maybe open another page so the python-wasm page is in the background.
+(Probably not needed.)
+
+3. Suspend your phone and wait 1 minute.
+
+4. Turn phone back on. The service worker *might* be completely broken and no
+amount of refreshing fixes it. Without the workaround below, the only option is
+for the user to clear all private data associated with the site, or wait a while
+(maybe an hour) and things maybe start to work again.
+
+I think this is caused by the page suspending in the middle of a "get stdin"
+call. This code below does seem to effectively work around the problem, at the
+expense of a page refresh when you return to the page. This isn't uncommon on
+safari anyways though, since it often dumps pages to save memory.
+
+This doesn't seem to happen on any desktop browsers (including safari) as far
+as I can tell, even when suspending/resuming a laptop.
+
+There may be a better fix involving changing how the service worker behaves,
+but that is for another commit, and another day.

New alerts

Network access

Supply chain risk

This module accesses the network.

Found 1 instance in 1 package

Shell access

Supply chain risk

This module accesses the system shell. Accessing the system shell increases the risk of executing arbitrary code.

Found 1 instance in 1 package

Uses eval

Supply chain risk

Package uses dynamic code execution (e.g., eval()), which is a dangerous practice. This can prevent the code from running in certain environments and increases the risk that the code may contain exploits or malicious behavior.

Found 1 instance in 1 package

Debug access

Supply chain risk

Uses debug, reflection and dynamic code execution features.

Found 3 instances in 1 package

Environment variable access

Supply chain risk

Package accesses environment variables, which may be a sign of credential stuffing or data theft.

Found 3 instances in 1 package

Filesystem access

Supply chain risk

Accesses the file system, and could potentially read sensitive data.

Found 1 instance in 1 package

Long strings

Supply chain risk

Contains long string literals, which may be a sign of obfuscated or packed code.

Found 1 instance in 1 package

URL strings

Supply chain risk

Package contains fragments of external URLs or IP addresses, which the package may be accessing at runtime.
