Updating an app with TiLP hangs & times out while calculator is on "Defragmenting" screen

[jojomoore2007]

Applies to: TI-84 Plus CE

Description:

When trying to update an app (by uploading a newer version), the calculator displays a "Defragmenting" screen for a while, and TiLP remains completely unresponsive. Once this finishes, an error message appears, due to a timeout. Choosing "Retry" successfully uploads the app, but similarly hangs for a short period of time while the calculator verifies the app.

Steps to Reproduce:

1. Get a newer version of an already installed app
2. Try to upload it
3. Timeout error
4. Retry
5. Success

In my tests, I've found that it takes around 30-60 seconds to actually complete the defragmentation step, and by then, it's already way past the timeout period.

Thanks for the report. Well, the issue has been known for a long time, but the workaround on the user side - retrying the operation after the defragmentation has taken place - is usually reasonably easy, if slightly cumbersome :)

On the libti* side, the fix might involve polling the calculator for defragmentation status information, when the given target model supports such polling.
