[ANNOUNCEMENT] lftp 4.8.0-1

[ANNOUNCEMENT] lftp 4.8.0-1

[Andrew Schulman]

lftp 4.8.0-1 is now available in Cygwin. This is a new upstream release,
with minor enhancements and bug fixes.  Please see
http://lftp.tech/news.html for the list of changes.

lftp is a sophisticated file transfer program and ftp/http/bittorrent
client. It supports multiple network protocols.  It offers tab completion,
command history, job control, and bookmarks. It can mirror sites and
transfer multiple files in parallel. It keeps trying interrupted operations
until it can complete them.

lftp / zlib problems

[Harri T.]

Hi all,

After updating Cygwin 32-bit we have had problems with all the combinations of lftp 4.7.7.-1 / 4.8.0-1 and zlib 1.2.8-3 / 1.2.11-1.

1. Command "mget -E myfile*" causes "zlib inflate error: incorrect header check" always with Core FTP server 1.2 if there is nothing to retrieve.

lftp myuser@myip:~> set ftp:ssl-allow 0; set ftp:passive-mode 1;
lftp myuser@myip:~> mget -E myfile*;

generating a stackdump file.

Is there something we can do to avoid these issues?

Br,

Harri

To add some weight to Harri T.'s message, I've reported the same problem twice:

OK. I'm sorry for the delay in dealing with this problem. Clearly 4.8.0 is
broken in Cygwin, and the build of 4.8.1 fails so far so that's no help.

Meanwhile 4.7.8 is out so I'll try that and see if it fixes the problems
with 4.7.7 and 4.8.0.

I just uploaded 4.7.8-1 as a test release. Once it appears in Setup in the
"Test" release, please try it and let me know if it fixes this problem. In
my brief testing it seemed to fix the problem for me.

Thank you for giving this matter some attention.

Since I last used lftp I was issued a new laptop running Windows 10. 
Previously I was running Win7. Win10 has been giving me a number of 
access problems, which seem to be resolved by running Cygwin in admin-
istrator mode. This particular problem with 4.8.0 goes away in admin 
mode, which is now my standard operating mode, so 4.8.0 is no longer 
a problem for me.

lftp 4.7.8-1 is now available in test. Please try that version and let me know
if it fixes the problem for you.
