Description Polo Talnir 2007-03-09 02:41:11 UTC
Description of problem:
wget with -nc aborts when it finds the first file that already exists.
Start a wget download and interrupt it (because it is too long, or
because the machine crashed or because the soup is getting cold).
Then try to resume the download using the -nc parameter: wget aborts
as soon as it finds an already existing file. The intended semantics
is that wget will skip these files and continue downloading those that
were not downloaded in the first run. Indeed, anything else makes the
program less than useful as it precluded decent resumption of a long

I compiled the official sources wget-1.10.2.tar.gz from and it works fine, just as expected,
continuing downloading from the point where it was stopped, skipping
existing files.

Version-Release number of selected component (if applicable):
1.10.2-8.fc6.1. I used this build on FC5 in order to check whether
the wrong behaviour that I found in the build (Fedora Core 5 update)
1.10.2-3.3.fc5 was fixed, but it was not. Both versions are wrong.
(surprising the the fc6 RPM installed without complaints in FC5).

How reproducible:

Steps to Reproduce:
1. enter the following command:
 $ wget -erobots=off -o wget.log -nH -r
(one line) and let it run for 2 minutes.
2. ^C to stop it.

3. enter the following command, including -nc -c (to continue download
   of a partially downloaded file, if any, and new files not-yet downloaded:
   wget -erobots=off -nH -c -r -nc
   (in one line).

Actual results:
  $ wget -erobots=off -nH -c -r -nc

====> notice the "Aborted" line. 

Expected results:

This is the output from my locally compiled wget from the GNU sources.

I can reproduce this. I have a core, if anyone is interested.

The abort happens at http.c, line 2599.

I don't know how it gets there, as hstat.res == -1 and thus we shouldn't be
inside the if @ 2559 (and then, inside the if @ 2561). Either it's a compiler
bug or the debuginfo package is wrong.

hstat = {len = 0, contlen = -1, restval = 0, res = -1, rderrmsg = 0x0, 
  newloc = 0x0, remote_time = 0x0, error = 0x0, statcode = 0, rd_size = 0, 
  dltime = 0, referer = 0x0, 
  local_file = 0x9bce378 "", 
  timestamp_checked = false, orig_file_name = 0x0, orig_file_size = 0, 
  orig_file_tstamp = 0}

rpm -q wget wget-debuginfo --qf '%{name}-%{version}-%{release}.%{arch}\n':

Comment 2 Ralph Loader 2008-02-05 19:34:31 UTC
Should this bug be closed?  I can no longer reproduce it.

Comment 3 Karsten Hopp 2008-02-07 11:20:43 UTC
Closing as FC-6 isn't supported anymore and more recent releases don't seem to
have this bug.
