Hi,
The current develop branch no longer compiles on macOS. I get lots of errors of the form

/Users/me/midas/src/history_schema.cxx:740:4: error: unknown type name 'off64_t'; did you mean 'off_t'?
  740 |    off64_t fDataOffset = 0;
      |    ^~~~~~~
      |    off_t
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.5.sd
k/usr/include/sys/_types/_off_t.h:31:33: note: 'off_t' declared here
   31 | typedef __darwin_off_t          off_t;
      |                                 ^

There are also similar errors about lseek64. This appears to have come in with commit 9a6ad2e dated 
23rd July, but I think it was merged into develop with commit 2beeca0 on 3rd of September.

Googling around it seems that off64_t is a GNU extension. I don't know of a cross platform solution but I'm 
happy to test if someone has a suggestion.

Thanks,

Mark.

Confirmed. No idea why off64_t is missing on MacOS. I will try to fix it next week.

K.O.

midas web pages that use overlays (dlgPanel, etc) are currently broken - if 
overlay does not fit in the visible window, it's bottom is truncated and control 
buttons like "create" and "cancel" are not visible, not clickable, page does not 
work.

when these pages were originally written, I am pretty sure these overlays were 
scrollable and this problem did not exist. I think that was broken recently, 
maybe withint the last year or so.

specific examples:

a) odb editor:

- open odb editor,
- click on "create odb link"
- click on "link target ...", a dialog overlay opens with a list of odb keys in 
the current directory
- select a directory with a large number of entries (i.e. "/Programs")
- alternatively, make browser window smaller
- observe the "ok" and "cancel" buttons are not visible, cannot be clicked
- definitely, there used be a scroll bar and one could scroll down to see these 
buttons.

b) history planel editor:

- open history plot,
- click on "configure this plot" icon,
- history editor opens,
- click "add active variables"
- select active event that has many variables
- observe that the list is cut off at the bottom, the very last variables are 
not visible
- alternatively, make the browser window smaller

I wrote this page and at the time this problem did not exist, there was a scroll 
bar and one could scroll up and down the list even if there were really many 
variables there.

Maybe this breakage is not from us, I see similar problems on other sites, so 
maybe browser behaviour changed recentlyshly.

I think Stefan write the dlgPanel code originally? I am not very familiar with 
it and I do not know if anybody changed it recently?

K.O.

I confirm the problem is there (at least under MacOSX Safari) and I will take care of it.

This problem was introduced by ZS in March 2023 with these commits:

https://bitbucket.org/tmidas/midas/commits/25b13f875ff1f7e2f4e987273c81d6356dd2ff53
https://bitbucket.org/tmidas/midas/commits/2a9e902e07156e12edecb5c2257e4dbd944f8377

by setting

 d.style.position = "fixed";

which prevents the scrolling. I have no idea why this change was made, so it should be fixed by the original 
author.

Stefan

Sorry about that. I could not figure out what was the reason for doing this. This was during the time I was working on the file_picker. I removed these lines and see no effect on the file_picker. I'll continue checking it affect anything else.

I confirm reported problem seems to be fixed in commit:
https://bitbucket.org/tmidas/midas/commits/7f2690b478d6dfb16b48fc98955093e6369b04c1

Big thanks to Stefan and Zaher for figuring it out quickly.

K.O.

I'm constructing a TMFeEquipment with this constructor:

MagnetFe(const char *eqname, const char *eqfilename) // ctor
        : TMFeEquipment(eqname, eqfilename)
    {
        fEqConfEventID = 3;
        fEqConfBuffer = "SYSTEM";
        fEqConfPeriodMilliSec = 1000; // in milliseconds
        fEqConfLogHistory = 1;
        fEqConfReadOn = RO_ALWAYS;
    }


When I start with a fresh ODB, the directories are created correctly, and e.g. the 
event ID is set correctly, but "Read on" is set to 1 (i.e. RO_RUNNING) instead of 
0xFF.
Now when I set it to 0xFF manually and restart, it gets overwritten to 7 
(RO_NONTRANS), which I guess is a relatively recent change and doesn't affect me 
negatively.

I think I've found a bug in MIDAS ...

Description: If you have an ODB subtree that contains only an array of BOOLs, you cannot edit them from the ODB webpage, although you can change them using odbedit (and probably from code as well). 

(If you use the dropdown menu to change any value from No to Yes, it just flips back to No immediately.)

But if you create a new key in that directory (doesn't seem to matter what), then you can edit the BOOLs from webpage. Delete that key, and once again you can't edit the BOOLs.

Can you please update to the latest develop versiokn of midas, and clear your browser cache so that the updated JavaScript midas library is loaded. Should be fixed by now. See attached screen shot where I changed every second value via the ODB editor.

Stefan

Thanks --- it looks like this commit (which we just missed by four days when we last updated MIDAS) resolves the issue for us:
https://bitbucket.org/tmidas/midas/commits/6af72c1d218798064a7762bae6e65ad3407de9d1

Thanks to Ben Smith for pointing us at exactly the right commit.

I would like to take the opportunity to encourage all to report bug fixes like this one to this mailing list.

This looks like a serious bug, many midas users would like to know when it was introduced, when found, when fixed 
and who takes the credit.

https://daq00.triumf.ca/MidasWiki/index.php/Custom_Page#modb

says that

If the ODB path does not point to an individual value but to a subdirectory, the 
whole subdirectory is mapped to this.value as a JavaSctipt object such as

<div class="modb" data-odb-path="/Runinfo" onchange="func(this.value)">

<script>function func(value) { console.log(value["run number"]); }</script>


In fact, it seems to return the JSON string of said object, so you'd have to write

console.log(JSON.parse(value)["run number"])

Indeed a bug. Fixed in commit

I commited a fix to mhttpd logic that decides which messages should be shown in
"red" colour- before, any message with square brackets and colons would be
highlighted in red. Now only messages matching the pattern [...:...] are
highlighted. The decision logic was moved into a function message_red(). K.O.

Problem:
If cm_set_transition_sequence() is used for changing the sequence number, the 
command odbedit> start/stop/resume/pause -v report the propre sequence but the
action on the client side is actually not performed!

Fix:
Local transition table updated in midas.c (1.226)

Note:
The transition number under /system/clients/<pid>/transition...
is used internally. Changing it won't have any effect on the client action
if sequence number is not registered.

We stumbled upon and fixed a "double free" bug in src/ybos.c causing crashes in
lazylogger writing .mid files in the FORMAT_MIDAS format (why does it use
ybos.c? Pierre says- for generic file i/o). Why this code had ever worked before
remains a mystery. K.O.

I fixed some minor bit rot in the example experiment: a few minor Makefile
problems, make the analyzer use the current histogram creation macros, etc. I
also added startup and shutdown scripts. These will be documented as we work
through them with our Summer student. K.O.
