Re: Attempt to read beyond end of stream

[Tarawerkz via 4D_Tech]

Peter and Chip,

Thank you both for the constructive feedback on the possibilities.

As the cause of the issue and the consequent resolution (if indeed possible) is 
one black-box, I have decided to go back to the most recent stable version and 
re-do the necessary changes.


Regards,
Ronnie

Re: Running AppleScripts from 4D under Catalina

[Keisuke Miyako via 4D_Tech]

it depends on how you implement automation.
are you calling osascript via launch-external-process?

to control the Mail app, normally you need to use 
AEDeterminePermissionToAutomateTarget
https://github.com/miyako/4d-plugin-apple-file-promises/blob/master/apple-file-promises/4DPlugin.cpp

to prompt the "4D is requesting permission to..." dialog and ask for the user's 
permission.
if the user agrees, the app will be added to the list of granted apps in system 
preferences/security/privacy. 

this is only for Apple apps, I think Outlook does't care.
if neither apps are responding, the reason must be something else.

Re: Running AppleScripts from 4D under Catalina

[nug via 4D_Tech]

I have no experience with this — at all— I remember reading that there are 
issues using Apple script with 10.14+
I believe there are new commands in 4D to manage email directly -
Try looking into those.

Also, sad as I am to say this, you will get better response from the new forum.

Running AppleScripts from 4D under Catalina

[Peter Adam via 4D_Tech]

I have an app where when the user wants to send an email from 4D, the program 
builds an AppleScript to communicate with either Mail or Outlook.

This has been working fin from v17R6 under Mojave but returns a message that it 
can’t find Mail on Catalina.

I have code signed and notarised the app, set the entitlements to include 
Automation in the build and code signing but when I install and run the app on 
Catalina the emailing still fails with the same error. Mail is definitely 
installed.

The Privacy preference does not show the application in the  Automation window 
as it does under Mojave.

This is all with 4D v17R6

Any ideas?

Re: Attempt to read beyond end of stream

[nug via 4D_Tech]

My first thought would be damage to the file from the hardware (bad block(s) on 
the disk, 
but I do not know your situation there
Another thought would be a crash/power outage/etc that occurred while 4D was 
writing the structure to disk, 
Or before the cache (4D’s structure, or disk) was flushed interrupting 
completion of the last dev changes

Re: Attempt to read beyond end of stream

My info is not very recent, but few years ago I analysed structure of
data and structure file. There are many auxiliary structures, but
actual data are stored in blocks, where each block have a prefix,
containing, between other, size of the block. If this field got
corrupted and contained some ridiculous big value, 4D would crash when
reading the data with the "Attempt to read beyond end of file ..."
error,

This error was hard to fix, because restore did not help (when it did
not read content of blocks) or crashed as well (when it did.) When
problem was in data file, error happened when 4D accessed particular
record, then it was possible to find that record in file and fix it
with hex file editor. With structure this would be much harder.

So, if this is the case, I am afraid you probably do not have other
solution then go to stable backup and then try to copy changes, if you
can open structure without crash. What I would suggest is to try to
exclude all other sources of problem, maybe moving the structure to
new empty folder, no plugins, components, settings or logs.

Peter Bozek

Thanks Chip,

I’ll try that, hopefully can find a version from not too far back.

Any idea what could have caused this?

Like Chip stetted, almost all are on discuss forum now. I don’t think support 
will help on a v15 db as they no longer support it.

Re: Attempt to read beyond end of stream

[nug via 4D_Tech]

Ronie,
-Go back to the originally damaged structure and try MSC on it again.
-go back to a previous version of the structure (backup)
-contact 4D support

While I personally do not like it….
Also there is a new forum, where nearly ever one is now.

Attempt to read beyond end of stream

[Tarawerkz via 4D_Tech]

Hi All,

I would like seek advice on an issue I encountered with a v15 structure file 
which has been in use for a long time.

Recently, when I logged in with the designer password to make some amendments 
to the code, I encounter a memory allocation error on a resource blob.
So I did a structure repair and compact using MSC utility.

After the repair, the original error is resolved but a new error appeared in 
its place,  
This time it is an attempt to read beyond end of stream (error code 200).
Subsequent repairs of the structure file does not remove the error.

The issue is data independent as it also appears with an empty data file.
If I were to log in as a normal user (not the designer account), the error is 
not encountered.

May I ask how I can recover the structure in this instance?

Regards,
Ronnie
Tarawerkz
