Bug?

[pier4r]

PS. low skill english below.

I have a lot of file to share but if my emule extreme 7.1 working on hash and is connected to kand and/ord ed2k , the memory usage grow up until 300-350 until crash.

If i not connect emule to kad and/or ed2k, i works fine.

why?

little suggest: i noticed that if emule calculate hash of small files (like txt) it update the know.met and know_64.met file. This work, for small files, stress a bit the Hard disk.
So, why you not implement an algorithm that work like this:
- if next 'x' (x = 1000 for example) files are smaller than 100MiB, calculate their hash and after update knowXXX.met files.
- if not
-- if next 900 files are smaller than...
--if not
---.....
-----if next 10 files are smaller than 100Mib calculate their hash...ecc...

Thanks for answer!

how many files do you share? remind yourself, there is no point in sharing millions of files with a small upload. you can do some calculations on how many bytes you can upload per day and if the result is a lot smaller than the amount of data shared you should reduce the number of shared files.

What do you mean by "working on hash"? Do you mean that this happens while hashing a file AND being connected to any network?

[pier4r]

i don't but billion of files for fast download (anyway is about 800Gib and 25.000 files)

Don't worry!

I put it because i take it from the p2pNET, so i think that it's rigth give back at least the hash code (or sources by source exchange). I can take from net, i can give!

Anyway this is no matter, i must share less files for avoid this crash? Why hashing work fine without huge of ram (like 85-100Mib) when emule isn't connected to kad/ed2k and if i connect it, after about one hour, crash?

Thx a lot

mumble, my english sux a lot.

For working on hash i mean this action: calculating (or recalculating) hash of files.
If exreme do it when isn't connected work fine else not (1).

(1): memory usage grow up from 85-100 MIB to 300-350 Mib in an hour and after this xtreme didn't work.

800 GB and 25k files is by far too much! reduce the number of files a lot! more than 5k is insane and i would not recommend anybody to share more than 3k files. the data should also not exceed more than 100 GB but imo 50 GB is quite a lot already. there is no point in sharing small portions of various files when it takes months to go through all files just once.

[tHe WiZaRd Of DoS]

... it's still strange that this bug occurs only when you're connected... maybe the problem is related to the files being published once you're finished hashing...

what a kind of response????

Is no matter how many files i share... the matter is the bug.

It's like:

- Maybe equations over fouth grade can't have a resolution formula.
- "Don't worry, we use only linear equation!"



Anyway, i write the bug for help the develop of xtreme (or emule), if you not care, it's ok.


@wizard: good point. So i must wait other 3 days.... now remain 3000 files left.

PS: omg my english.

what kind of response this is? a sane one. nobody expects emule to run in a way you want it to run. wrong usage can produce unexpected results and i would not look into it unless i know the user is not sort of abusing the program.

i don't care if you like it or not but that's how i run things.

I don't want a special emule mode... I hope that emule work in the same mode (without crash) with 3.000 or 2.565.463.545.654 files.

If emule work fine with 200 files, 500 files, 1000 files why not with 25.000?

It's an algorithm, not an organism.

If there is a limit, the application should be warn the user.

e.g.: If i have a scientific calculator and i write: mum + dad + 25, the calculator return "error".

but ifcalculator works with 25 + 25, and i write: 25 + 25 + 25 + ... + 25, if calcutator permit this ( = great number of digit is allowed) , i expect that calculator works else i must see "error too many digits".

If emule was a real mule, so, maybe the high load can kill it... but is a program not an organism.

(this is my point of view)

PS: again sorry for sintax

because code can be optimized for certain scenarios. it might work with other but it might as well not. it might even be that you are overloading your system doing this. the increased ram usage is the number one sign that something must be wrong when you share so many files.

This is a better response.

Sure!

In fact i don't want "emule must work with only 100 Mib".
Emule can grow up until 1Gb (sure, optimization are welcome), but without crash!

Another example.... (the initial topic): why emule hash and work fine if i don't connect to any networks (but clients can search me by source exchange) but if i connect to networks it crash?

So emule work fine, probably there is a conflict (maybe as decribed by wizards of dos) when i connect to networks.

PS: anyway i find a lot of "idiot" threads/post against you on different forums (morphxt, stulle, xtreme, ecc..).
I don't want to dispreciate your work, in fact i use xtreme... i want only to report a bug plus a point of view (e.g. if more than 5000 files is wrong way, warn the user ).

[Stulle]

i am warning here, ain't i?! no point in nagging dialogs, imo...

true. Stop it.

Good work.

[pier4r]

Just finish the hasing of files... now work as expected.

So, the crash appears while emule make hashs.

Thank you for reporting this bug.

Fixing bugs is a lot of work. Everything works fine when emule is used the way it should be used. That's why there is no need to fix this bug. That's all.
