Miranda loses privileges to write after an unspecified amount of time

[Vulpix]

Hello!

I'm having - and have been having this issue for a very long time now. Maybe months... I've discussed it with a few people before but I can't seem to be able to reproduce it _reliably_ (but it does happen all the time!) or to figure out why it's happening.

Essentially what happens is - Miranda loses the ability to write anywhere but to the already opened file handles (so for example the dat file for the database is unaffected, but everything else is).

I am not sure if this pertains only to windows 10 but I don't remember this happening on any other version.

Symptoms:

- New avatars retrieved from contacts cannot be saved
- File transfers in both ways instantly fail
- checking for updates comes back with an error message "error checking for updates".
- if you have netlog enabled, netlog just suddenly ends and doesn't write any more data.
- it happens after some time of miranda running, i.e. it's not something that happens when you start it.

Netlog doesn't work so no traces - you simply see the last message that miranda was able to write before it lost the ability to do so. I've checked it and it's just a generic message from steam protocol, polling for data. Nothing unusual.

Console still works.

Checking for updates shows this:

-> unable to write.

You get the idea.

When I exit miranda, it closes without a trace but it also generates some errors, a regular windows appcrash:

It also writes a bit of data into the netlog again! Nothing unusual once more though... but it's as if it suddenly regains its ability to write.

It also wrote THREE crash dumps at once:

Initially I thought it happens at a specific time but it seems to be a completely unspecific time. Sometimes it works just fine for a few days, other time I wake up and miranda is already "broken".

How can I help diagnose/debug this? I checked windows event logs around that time but I found nothing.

It's not UAC because as I said before, Miranda runs just fine when you first start it. Furthermore I tried setting miranda to run as administrator (even though I am one) and it still happens. On top of that, it also happens on a computer where I have disabled UAC completely and I'm running as the built-in administrator (don't do this on your windows 10, it disables store and all the "apps"). It also happens on a completely normal windows 10 though, with UAC turned on.

What is happening here? How can I troubleshoot this to get it fixed? It's been bothering me a lot in the past few months but I thought it might have something to do with me using remote desktop. However in this case I have not used it and it still happened, and it was on a completely different PC as well!

Hah!

This is SUPER IMPROBABLE but it appears that ghazan has fixed this. It is so funny that after months of it annoying me, I finally wrote a long post about the problem and it's already fixed

Apparently it's fixed by: http://trac.miranda-ng.org/changeset/17206/ (and the subsequent patch)

I'm going to observe the issue and if it does not reoccur within 14 days, you can mark this as resolved.

Thanks @ghazan !

[AnrDaemon]

I skimmed through the commit and I think I understand why this could have caused issues. Nice one, ghazan. Hat off.

[Vulpix]

Unfortunately, the issue occurred again today So it's not fixed. I'll talk to Ghazan.
