CvPCB window freezing on 'filter by pincount'

[DaveyPocket]

Opening the "Assign PCB footprints to schematic symbols" window, checking the "Filter footprint list by pin count" button causes the KiCAD to hand for around 15-20 seconds with no results showing up in the right-hand (3rd) pane. Un-checking the button requires another 15-20 seconds but then the issue is resolved. Filtering by any other option does not cause this problem to occur as far as I can tell.

+1 affects me exactly as described. Kicad 5.0.1 on Windows-7 64-bit.

[Mark Robson (markxr)]

Cannot actually seem to filter footprints by pincount. This worked ok on earlier versions of Kicad.

[Wayne Stambaugh (stambaughw)]

This appears to be fixed in the current 5.0 branch nightly build 5.0.1-29-g839ade2c0 at least I cannot reproduce it. It may have been due to an issue with older dependency libraries and build tools that caused the issue. Would someone else confirm this? The installers for this build can be found here: http://downloads.kicad-pcb.org/windows/testing/5.0/

[Mark Robson (markxr)]

I installed the latest testing build and the bug is still happening for me:

Version: (5.0.1-33-g76adf7dbe), release build

@Mark, using the i686 or x86_64 build?

[Mark Robson (markxr)]

x86_64 build shows the problems.

I tried installing the i686 build on a VM, it seems fine (can't reproduce, it works as expected). I don't know if the difference in behaviour is due to the setup of these Windows machines, or the different architecture build.

[Wayne Stambaugh (stambaughw)]

I'm am not seeing this on my 64 bit builds on windows 10 pro. I wonder if it's a matter of dependency library differences between my builds and the installer builds.

[Nick Østergaard (nickoe)]

@Wayne, I don't think this is about the toolchain. We are using more or less the same now. The report is against the 5.0 branch.

Could you try the build I provide for the 5.0 branch?

@Nick, no problem with the latest 5.0 nightly using installer kicad-5.0-jenkins-82-x86_64.exe.

[Nick Østergaard (nickoe)]

So as you tested with the same or almost same builds, I guess there are some other differences. Maybe the steps to reproduce are not accurate.

[Mark Robson (markxr)]

I am able to reproduce this on the win7 64-bit Laptop. I guess it is something related to libraries or graphics drivers. A 32-bit VM does not show the bug.

[Mark Robson (markxr)]

Is it also possible that this bug is related to Antivirus software?

[Wayne Stambaugh (stambaughw)]

@Mark, I wouldn't think AV would be an issue since the filtering doesn't require any file I/O. You can always temporarily disable your AV and test it. I have my AV (windows defender) disabled.

[Mark Robson (markxr)]

I found the problem!

It was caused, I think, by an upgrade from an earlier Kicad, the file fp-lib-table had bad contents.

I removed the file %userprofile%\Appdata\Roaming\kicad\fp-lib-table, and now it's working perfectly.

This tip was provided on the eevblog forum here: http://www.eevblog.com/forum/kicad/kicad-5-assigning-foot-freezes/msg1960232/#msg1960232

[Wayne Stambaugh (stambaughw)]

@Mark, do you know if your old fp-lib-table had any github plugin entries?

[Mark Robson (markxr)]

Yes, it had many, possibly all of them, I think they're all the standard ones. It starts:

(fp_lib_table
  (lib (name Battery_Holders)(type Github)(uri ${KIGITHUB}/Battery_Holders.pretty)(options "")(descr "Batteries and battery holders"))
  (lib (name Buttons_Switches_SMD)(type Github)(uri ${KIGITHUB}/Buttons_Switches_SMD.pretty)(options "")(descr "Buttons and switches, surface mount"))

etc...

[Wayne Stambaugh (stambaughw)]

I'm pretty confident this was your issue. Github libraries can be very slow depending on the quality of your internet connection. This is why there was only a lag the first time you toggled the filter by pin count button. KiCad is now packaged with the libraries to be installed locally so this should eliminate the problem unless you have a very large number of libraries. I'm going to change the status of this to fix committed since this has been fixed by the packaging changes. Please change the status back to new if the problem occurs again.
