Mega.nz download large file problem (maybe only in private mode ?)

[Som30ne]

Re: Mega.nz problem with large files
A few days ago I tried downloading a large file ~4GB from mega.nz,
using Vivaldi in private mode.
It downloaded approx. 40% and crashed without any message (Vivaldi disappeared).
My machine has 32GB RAM.
I searched and found somewhere that there's a limit on the data storage available when using private mode.
This made me wonder - In private mode, especially on 64 bit OS, why on earth would you use disk storage at all.
Use memory heap, store blobs in a key-value map, and be done with it.
If there's enough RAM, it will never write anything to the disk.
If there's not enough RAM, the OS virtual memory manager will drop stuff to page file on the disk.

(Eventually, only firefox was able to download this)

@Som30ne I recommend you to use Jdownloader 2 to download large files.

@Som30ne I belive Mega uses the FileSystem API to store files. It's a mess, because in practice it will occupy the disk space at least twice, maybe even 3x from what I remember last I tested downloading:

• Downloaded in encrypted chunks to Cache
• Decrypted to file(s) in File System
• User download location.
• Does not clean up properly after

Do you have an example of such a 4GB file? I don't have such large files in my Mega to test with.

I don't think memory (RAM) matters, what matter is free disk space, according to this Chrome will allow up to 80% of total disk space.

But even if running out of allowed disk space, Vivaldi should not crash. Maybe it lacks proper exception handling for the API. If you're able to reproduce the crash in a clean profile, please make a step-by-step reproduction report:

@Pathduck
You don't actually need a large file.
The real scenario was to download a folder as a ZIP.
(Run vivaldi in private mode, go to mega,
right click a large enough folder, select download as ZIP)

BTW - Google Chrome, incognito mode, crashed in the same manner.

** My suggestion was more general -
in private mode (on 64 bit OS), don't use actual disk access.
Implement the API to use memory instead.

@barbudo2005
Thanks for the interesting suggestion.
I would need to try it for the real scenario,
which was not to download a "real" 4GB file,
but to download a folder in mega as zip file.

I can confirm Vivaldi 3.4 (clean profile) crashes when attempting to download a 1.75GB folder from Mega as ZIP. Please report the bug on link I posted. (they really borked Private mode on this release...)

Jdownloader2 has plugins for almost all the sites, has up to 20 chunks for download, can resume, and for Youtube you only need to copy the URL of the video to download separately the sound, the video, the subtitles in maximum resolution.

@Pathduck I often download from Mega but I have their extension installed, because without it I often reached the daily download limit, which seems to not happen if using the extension, can you retry with that?

@iAN-CooG @barbudo2005
I wanted to avoid installing any additional software.
I don't like installing software that I only use for rare occations.
(I also try to avoid install something just for a single use,
as most every installer out there leaved TONS of garbage after uninstall)

If I would install any software for mega itself, I would go and install the mega Sync, or the mega command line tools.

Ofcourse I would have preferred if these packages would have not required any installation, and would have been just a compressed file, to extract at your convenience, where you know it does not leave any garbage behind
(Except maybe in the windows registry, which is also something I really dislike,
or in other words, F***in clean after yourselves !)

I looked as some posts regarding JDownloader,
apparently it does not always download the directory structure as it is in the cloud.

So -
As I said -
It would be nice, helpful, and preferred, to be able to download using vivaldi,
in private mode, using RAM, without ever touching the disk for any temporary data.
(but if software installation is required - I would use the tools for mega itself)

I agree, I also think it would be nicer to be rich, beautiful and healthy, but most of the times we have to make do with what we have in the meantime, until something better happens. Don't hold your breath waiting for it, maybe it won't ever happen.

Well, to be honest, this is really "not my problem" - mainly as I don't download a lot from Mega anyway
But out of interest I just did a quick test, and there's not really any difference in the actual method used to download files through the extension. It still uses Cache > File System > Download. And it's not any better at cleaning up after itself, leaving its files around after download in the profile.

Since this thread was about Vivaldi crashing in private mode, it wouldn't help anyway, as apparently the extension won't work in Private windows, even if explicitly allowed for Incognito. It just redirects any requests for mega.nz to chrome-extension://bigefpfhnfcobdlfbedofhhaibnlghod/mega/secure.html and the error message "bigefpfhnfcobdlfbedofhhaibnlghod is blocked. Requests to the server have been blocked by an extension."

So using the extension is not a workaround to avoid the crashes, which is the primary issue in this thread. Vivaldi should not crash, full stop, no matter what it tries to download. And @Som30ne needs to report the issue if the team is to know about these crashes and be able to reproduce and maybe fix it some day.

Yes, but "nice, helpful and preferred" does not matter at all before you create a feature request, please do so here:
I notice you opened a request

Yes, I did.
When I was sure it's not only on my machine,
and it was confirmed to happen on other machines as well,
I did report a bug, and also submitted a request to implement the "in-memory" behavior.

We all know this->

too well
