Downloading nightly builds - resume
« on: October 12, 2006, 02:58:52 am »
About process of downloading from berlios - can it be resumed? I has a very bad connection (modem, 26.4 kbit/s) - so if i try to download 5 mb file - i must to do this 4-5 times - it downloads to 60% for example, then error, then downloading again from 0%, then error in 45% and resume from 0% again..... may be it is any way to resume? any mirrors?

You are right it does not resume the download at where you were. But, I have been able to download the nightly build using SDM. I would try it and see if it errors out for you. I use the SVN normally to update codeblocks. But, unless I use SDM I can't seem to get a download that does not error out. I am using windows so Linux might have solutions that are better. I am using 56K modem connection.

Note: The SDM does resume for some sites for me.

Note 2: And, if you stop the download for Berlios it lets you choose to continue the download. I have no idea why pause does not let you resume. Resume is an FTP server function that all servers do not support.

Note 3: You can stop downloading a file (even after you paused it); and, then highlight the file and pick "Retry File" and it gives you the option to continue the download. If you get an error also use "Retry File".

Why don't you guys use wget?  :shock:

It doesn't need Java and is not mega-bloated and mega-slow like everything in Java. Plus... it *can* resume downloads...

Ok, i tried to look log of downloading (using FlashGet...), so i see interesting things.... i'll post 2 logs for different files - first is http://download.berlios.de/codeblocks/CB_20061009_rev3050_Ubuntu6.06.deb - i can't to resume it's downloading, and second is http://ftp.osuosl.org/pub/lfs-livecd/lfslivecd-x86-6.2-3.iso - i can resume it's downloading (as any other file - this is for example)....
I added my comments to log (marked as in c++).

this log is about downloading from berlios:

So... i dont know why, but berlios don't want to answer "HTTP/1.1 206 Partial Content", it always answer "HTTP/1.1 200 OK" and so all downloaders download files from first byte, not from last place :(.

I tryed FireFox's downloader, also - FlashGet and SDM - all of them don't want to resume... i dont think that wget will resume - if host don't say that it send partial content - downloader will download from first byte.... if no - i think that downloaded file will be corrupted because host will send content from first byte too....

You're right, the BerliOS http download server indeed doesn't support range... :shock:
On the good side, however, I just tried the BerliOS public ftp server, and it supports resume just fine.

So... we only need to put the nightly builds onto the ftp server instead (if that works in an acceptable way with the release system).

Found a windows file downloader that should work OK downloading CB.
Tim S

http://dfast.sourceforge.net/

From Site:

wxDownload Fast (also known as wxDFast) is an open source download manager. It is multi-platform and builds on Windows(2k,XP), Linux and Mac OS X. Besides that, it is a multi-threaded download manager. This means that it can split a file into several pieces and download the pieces simultaneously.

Created in C++ using the wxWidgets(wxWindows) library.
