05 May 2021, Zaher Salman, Forum, m is not defined error
|
We had the same issue here, which comes from mhttpd.js line 2395 on the current git version. This seems to happen mostly when there is an alarm triggered
or when there is an error message.

 07 May 2021, Zaher Salman, Bug Report, modbselect trigget hotlink
|
It seems that a modbselect triggers a "change" in an ODB which has a hot link. This happens onload (or whenever the custom page is reloaded) and otherwise
it behaves as expected, i.e. no change unless the modbselect is actually changed. Is this the intended behaviour? can this be modified? |

|
I found the bug. The problem is triggered by changing the firefox window. This calls a function that is supposed to change the size of the history plot
and it works well when the history plots are visible but not if the history plots are hidden in a javascript tab (not another firefox tab).

10 Oct 2022, Zaher Salman, Suggestion, JSON-RPC function to read files 
|
Hello ,
The midas sequencer uses the function js_seq_list_files to get a list of files in the /Sequencer/State/Path with extension *.msl. It would be nice to generalize |

05 Nov 2022, Zaher Salman, Suggestion, histories capture 'ruy'
|
The histories capture key events from 'r' 'u' 'y' and 'Escape' for various functions like rescaling etc. However, this also means that if we include an
editable modbvalue and a history in the same custom page then changing the modbvalue to something that includes 'ruy' is not possible.

|
I agree with you, option 2 is better and works well.
The only problem is that if you are showing multiple histograms in the same window the keyDown even will affect all of the histories in the window.
This may be the intended behaviour, but I think that if we can find a way to have the event affecting only the intended history (focused element for example) |

19 Jul 2023, Zaher Salman, Bug Report, access to filesystem through mhttpd
|
Have you actually been able to read /etc/passwd this way? I tested this on a few of our servers and it does not work. As far as I know, there is access
to files in resources, custom pages etc.

Somehow I don't understand why people's reply is only in my mail box.
So I pasted them here. I hope they don't mind and these information may be useful for others.
