Hi Everyone, This might be a corroboration of this http://lists.gnu.org/archive/html/bug-wget/2018-10/msg00049.html and this https://bugs.launchpad.net/ubuntu/+source/wget/+bug/1715481
I use wget to backup my cellphone running Palapa Web Server, and it has worked well for me for years. Since upgrading to OpenSUSE Leap 15, I have been having corrupted files. My method is $ wget -r -N 192.168.2.100:8080 and if the connection is interrupted for any reason, the next time I call wget it would complete any incomplete files. And since Leap 15, I have been getting gradually corrupted backups. I was tearing my hair out looking at wgetrc and other things. With one long file that I knew was incomplete, I got a Not Modified - omitting download, even though I knew the file sizes were different between the server and wget's copy - though the wget man page explicitly states that if the file sizes do not match, -N will trigger a download. I tried on OpenSUSE 42.3 (wget 1.14) and the incomplete file triggered a download, even though wgetrc was identical. Again, on Leap 15, I compiled 1.20.1 (latest), 1.17.1, and then finally with 1.16.3 the behaviour went back to what I expected (and I got my corrupted phone backups fixed). Was a bug possibly introduced in 1.17 with the support for --if-modified-since? Version shipping with OpenSUSE Leap 15: GNU Wget 1.19.5 built on linux-gnu. +cares +digest +gpgme +https +ipv6 +iri +large-file +metalink +nls +ntlm +opie +psl +ssl/openssl Last version I tried where "wget -r -N" works as expected: GNU Wget 1.16.3 built on linux-gnu. +digest +https +ipv6 -iri +large-file +nls +ntlm +opie +psl +ssl/gnutls I'm open to the possibility that there may be something else causing this bug, I have not found many mentions of it, but then again it is subtle. You get pretty confident when you just let wget do its thing, so there may be a lot of incomplete files out there... :) Thanks so much for your help. I can provide any other info that would be helpful. Lawrence Wade Ottawa, Canada
