dlogic Posted January 2, 2006 Report Posted January 2, 2006 hey utorrent is compressed with which exec compressors???and how can i decompress it
boo Posted January 2, 2006 Report Posted January 2, 2006 it is compressed with PECompact and it can't be decompressed I think.
dlogic Posted January 2, 2006 Author Report Posted January 2, 2006 can i have the decompressed version of utorrent
boo Posted January 2, 2006 Report Posted January 2, 2006 You have to ask ludde (the developer of µTorrent),but I don't think he will give anyone a decompressed versions because they can be hacked then.
boo Posted January 2, 2006 Report Posted January 2, 2006 You can do many things with resource hacker, what exactly do you want to do?
Ultima Posted January 2, 2006 Report Posted January 2, 2006 Not going to happen. People have requested uncompressed versions before, but to no avail.
1c3d0g Posted January 2, 2006 Report Posted January 2, 2006 Yeah, don't count on it. 99.9% of the time people plan to do nefarious things with an uncompressed program, so it's not gonna happen I'm afraid... :/
spliff99 Posted January 2, 2006 Report Posted January 2, 2006 Isn't it easy enough for a determined cracker to grab the decompressed code from memory?
Firon Posted January 2, 2006 Report Posted January 2, 2006 You don't have to reshack it to change the icons.http://www.utorrent.com/faq.php#How_can_I_change_the_system_tray_icon_.2F_GUI_icon_for_.C2.B5Torrent.3F
comrade Posted February 18, 2007 Report Posted February 18, 2007 Why are packers bad:http://f0dder.reteam.org/packandstuff.htmBasically, if Windows wants to free memory, it cannot page out uTorrent code to disk cause the code in memory is different from the code on disk (because of PECompact).
war59312 Posted February 18, 2007 Report Posted February 18, 2007 Little out dated comrade... Good luck!!
bedrock Posted February 18, 2007 Report Posted February 18, 2007 Is easy enough (for those with a little knowledge) to decompress,find OEP, dump from memory, repair imports.But like people have already said, why bother, unless you want to created hacked up versions (and if you have the skill to do this, then i would of thought you could unpack it)uTorrent is still my favourite clientby far, and i'm glad of the recent update, i just really wish uPnP worked correctly in Vista (roll on 1.7)--bedrock
Falcon4 Posted February 18, 2007 Report Posted February 18, 2007 Basically, if Windows wants to free memory, it cannot page out uTorrent code to disk cause the code in memory is different from the code on disk (because of PECompact).You shouldn't be paging off to disk anyway. Ever. At all.(Plus, if it's good enough for my 386 with 16mb RAM to run, it's good enough for your GHZ Whateverbox to run too.)
Ultima Posted February 19, 2007 Report Posted February 19, 2007 µTorrent itself doesn't use much memory anyhow, it's just the disk cache that does (which µTorrent manages on its own, and yes, shouldn't be swapped out).
Falcon4 Posted February 19, 2007 Report Posted February 19, 2007 Hrmm... as a side note, I don't know if it's a bug or not, but uT's memory usage spirals out of control when the combination WinNT4 + big disk + slow CPU + fast download (1MB/s) + all caches disabled... in order to stop this, I actually have to turn ON write caching and limit the cache size to like, 8mb. Dunno if that's a bug though... but I encountered it when I was downloading data from another computer =\
comrade Posted February 22, 2007 Report Posted February 22, 2007 war59312, why is outdated? the paging scheme that was in NT is still in present in 2000, XP, VistaFalcon4, there is no need to be arrogant. The point is not in paging to disk or not paging to disk. You make it sound like its a crime. The truth is Windows does it when it thinks its appropriate to do so.The point is that having an EXE compressed PREVENTS Windows from paging it out properly - instead of simply removing it from memory, and later re-reading it from uTorrent.exe, Windows has to write out the uncompressed data to pagefile.sys, and reload it from there. As well (another point mentioned in the article), having a compressed exe SLOWS DOWN loading of uTorrent - that's because instead of simply mapping the EXE to memory and reading it from disk on-demand, it has to read and decompress ALL of uTorrent.Personally, I would like uTorrent to take up 500KB more on my disk than have all these negative effects above.
Firon Posted February 22, 2007 Report Posted February 22, 2007 decompressing isn't a big deal. it's only 350KB uncompressed. I've run both a packed and unpacked version and there's really no difference.
Firon Posted February 24, 2007 Report Posted February 24, 2007 I haven't even noticed a difference in its paging behavior. Even the packed version seems to be able to have stuff paged to disk.
Stone Posted February 25, 2007 Report Posted February 25, 2007 comrade, from your link: "So, the larger you executable, the worse it is if you compress it"µTorrent is not a large exe no matter how you look at it.
