Some RCP Queries Result in a WeatherCat Crash

[The Grand Poohbah]

[Update] It's the RCP query that causing the crash, not WeatherCatRCP. To test this I entered a RCP query for the External Temperature Basic Graph in the Safari browser. It caused WeatherCat 3.1.3 to crash. If I enter a RCP query for System Information, WeatherCat 3.1.3 doesn't crash. Here are the two queries (192.168.0.215 is the local IP address of the M1 Mini running WeatherCat 3.1.3):

http://192.168.0.215:49255/image/getBasicGraph/1 (crashes WeatherCat 3.1.3)
http://192.168.0.215:49255/discovery/systemData (retrieves WeatherCat 3.1.3 System Data)

How to replicate it on an iPhone:

1. Open WeatherCatRCP (the iOS app)
2. Select the More tab.
3. Select Basic Graphs
4. Select External Temperature

WeatherCat (the macOS app) crashes.

WeatherCatRCP is version 1.2 (190618) running on iOS 15.5 and was connected over the "Local" network to WeatherCat version 3.1.3 on a M1 Mini with Monterey 12.4.

[Update] The WeatherCat crash leaves WeatherCatRCP in "where did my server response go" limbo. Leave WeatherCatRCP alone until after WeatherCat restarts. WeatherCatRCP will find the restarted server and continue as normal.

This is very strange since WeatherCatRCP is making a Rich Client Protocol (RCP) request and waiting for WeatherCat to respond. When this occurs, WeatherCat crashes and WeatherCatRCP is abruptly disconnected.

Only a Basic Graph, Custom Graph, or CTW request causes the WeatherCat crash.

Has this happened to anyone else using WeatherCat 3.1.3 or WeatherCat 3.2?

Dear Grand and WeatherCat troubleshooters,

I just discovered this crash situation:

1. Open WeatherCatRCP (the iOS app)
2. Select the More tab.
3. Select Basic Graphs
4. Select External Temperature

WeatherCat (the macOS app) crashes.
. . . .

Sorry, I lost this posting and haven't had a chance to try this until now.  I followed your steps and couldn't get WeatherCat 3.1.4 to crash for any graph type or Custom Text Box.  I am running the same version of WeatherCatRCP as you - version 1.2 (190618).  The only difference is that I am on an Intel Mac Mini running macOS 10.14.6 (18G9323) Mojave. 

Could this be an OS issue somehow?  Can anyone else running Monterey give this a try and see if they can reproduce the crashes? 

Cheers, Edouard

I ran the same query (Basic Graphs, External Temperature) on trixology-eng.com (v3.20, Build 223 (64 bit)) and did not get a crash. The query URL syntax is "http://trixology-eng.com:49255/image/getBasicGraph/1"

Crash:
WeatherCat 3.13 Build 155 on macOS Monterey 12.4 on Mac mini (M1, 2020).

No crash:
WeatherCat 3.14 on MacOS Mojave 10.14.6 on Mac mini (Intel)
WeatherCat 3.20 on ? (trixology-eng.com)

Dear Grand and WeatherCat troubleshooters,

I repeated your experiment on trixology-eng.com and it does not appear to crash the WeatherCat installation there.  So your observations stand.

Does look unfortunately like a Monterey macOS bug.

Oh well, . .  . . . Edouard

Anybody using macOS Monterey willing to confirm the crash? If WeatherCat does crash, it will not be painful and will restart quickly.

I updated the Mac mini (M1, 2020) to macOS Monterey 12.5 and it still crashed.

I’m on Monterey on my iMAc, but not running WeatherRCP, so can’t help. Sorry.

You don't need to test it with WeatherCatRCP. You can test it by entering a url in your web browser. Substitute the local IP address of your iMac for the 192.168.0.215 in the following URLs:

Enter http://192.168.0.215:49255/discovery/systemData to verify that you can communicate with your local WeatherCat server. This will retrieve an XML file containing the System Data for your WeatherCat server.

Enter http://192.168.0.215:49255/image/getBasicGraph/1 to retrieve an XML file containing the temperature chart in hexadecimal. This may cause your WeatherCat server to crash.

Mac mini, macOS Catalina (10.15.7), Intel Core i5, WC 3.20 Build 220:

The first url dumped the XML file as expected.

The second url caused WC to "quit unexpectedly" except it was expected! Crash report available, if desired.
Of course, WC Restarted on its own.

Confirmed the crash when calling for a custom graph from WeatherCatRCP. WC V3.20 Build 224 and macOS Monterey 12.5 Mac Mini (M1 2020). Crash report attached for reference.
