Perfparser exits with code 1 (TCP Socket error) when opening a perf.data file

[juanluishortelano]

Bug description
When opening a perf.data file from gui Hotspot outputs the following error:
"The hotspot-perfparser binary exited with code 1 (TCP socket error)."
Upon restarting the program it loads the perf.data file just fine

To Reproduce
Steps to reproduce the behavior:

1. Download hotspot-v1.2.0-x86_64.AppImage
2. Create a perf.data file from terminal or using the Hotspot record data function
3. Open file from GUI
4. Error appears
5. Restart Hotspot to load perf.data file correctly

Version Info:

• Linux Kernel version: 4.15.0-50-generic
• perf version: 4.15.18
• hotspot version: hotspot-v1.2.0-x86_64.AppImage

can you attach such a perf.data file that produces the issue? or are you saying that restarting hotspot "fixes" the load? Does this mean that loading the first perf.data works, but a second one fails? I've never seen this, so I'm really wondering what's going on here

I have the same issue.

It looks like the appimage is managing to look outside itself, on my actual system, for Qt 5.10, but my system (Ubuntu 18.04) only has 5.9 available:

ah, that's a packaging bug in the AppImage then. Thanks, I'll try to reproduce and investigate that issue.

[milianw]

Please try the continous build package for the patch above, it should be ready in a few minutes I hope

[milianw]

https://github.com/KDAB/hotspot/releases/tag/continuous should help now, I hope - please verify that it's actually fixed

[milianw]

I'm assuming it got fixed, if not please chime in

@milianw I get this error on Ubuntu 18.04 using the v1.2.0 AppImage release:

/tmp/.mount_hotspo5FHjdd/opt/lib/x86_64-linux-gnu/libexec/hotspot-perfparser: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.10' not found (required by /tmp/.mount_hotspo5FHjdd/opt/lib/x86_64-linux-gnu/libexec/hotspot-perfparser)
"The hotspot-perfparser binary exited with code 1 (TCP socket error)."

It happens when I try to load a perf.data file that I've recorded manually (using the command specified on the 1.2.0 release page), and it also happens when I click the "view results" button after recording an execution using the GUI. But weirdly, if I close the program (after getting the error) and then open it up again, it immediately loads the results page for the previously-recorded perf.data :S

Edit: Ah, sorry, I see that a new issue has been opened here: #197 #202

[milianw]

you probably mean #202, but yes - just use the continuous build for now to workaround this issue @josephrocca

[josephrocca]

Yep, continuous build works a treat - thanks for this great software!
