medm's Issues

Are there release notes?

The file medm/medm/RELEASE_NOTES only goes up to 2.3.1, which was many years ago. Are the changes made in subsequent releases documented anywhere?

text entry widgets freeze after ~30 minutes

Two reports of this problem:

Nicholas P. DiMonte:

I have been creating new displays this shutdown and have experienced that medm
will stop accepting input from the keyboard, yet the mouse is still functional.
This problem appears to happen within 20-30 minutes of when I start editing a
display. I have to exit medm and restart it to continue with my edits.

The MEDM freeze happened again on 32idcws.

Here's what I did:

1. I rebooted 32idcws and then logged in as the user account (usr32idc).
2. I started MEDM using their start script (start_epics)
3. I opened dozen MEDM screensn, including one motorx_all.adl
4. I spent five minutes changing values on the motorx_all.adl screen, and all the changes were successful.
5. I gave up trying to reproduce the problem and ssh'ed into other linux machines to do more productive things.
6. I returned to MEDM (25 minutes after launching it) and found that I could no longer enter any text into motorx_all.adl. I can open new related displays. Buttons and menus still work, but I can't enter text on any text-entry fields (on both the adls that were open originally AND new ones that I open since MEDM froze).

I confirmed that my copy of MEDM was the only one that was running on the system. I think you should be able to reproduce the problem by simply opening a medm screen with a text-entry field and letting it run in the background for a while. I don't believe there was anything I did to cause MEDM to freeze.

MEDM not responsive after lengthy image acquiring in "continuous" mode

MEDM stays in "Collecting" mode after acquiring images in continuous mode for about an hour.
Acquiring stopped after clicked on "stop", but stop responding afterwards to other button clicks.
This may or may not be related to Pixel format =Mono12Packed, and Image1 "Array callbacks"=Enable, image1 Pluggin Enable. (see 2nd attached screen shot).

MEDM compile error on ubuntu 18.04 - missing libXm.a

Compiling MEDM with Epics 7.0.4 on ubuntu 18.04 got this error:

I found libXm.a under /usr/lib/x86_64-linux-gnu and made a link under /usr/lib:
libXm.a -> x86_64-linux-gnu/libXm.a
But the error persists.
Am I missing some thing in the configuration settings?
