Fetch of xz distfile fails - connection timeout()

[richard@…]

expected results: latest version of xz, 5.0.5, retrievable from ​http://tukaani.org/xz/

actual results: as per macports log file, fetch fails due to connect() timeout on all mirrors.

thus, any package depending on xz (e.g., gtk2) fails to download.

===================================
pertinent log file contents:

...
:debug:fetch Fetching distfile failed: connect() timed out!
:notice:fetch --->  Attempting to fetch xz-5.0.5.tar.bz2 from http://tukaani.org/xz/
:debug:fetch Fetching distfile failed: connect() timed out!
:notice:fetch --->  Attempting to fetch xz-5.0.5.tar.bz2 from http://svn.macports.org/repository/macports/distfiles/xz
:debug:fetch Fetching distfile failed: connect() timed out!
:error:fetch org.macports.fetch for port xz returned: fetch failed
...

===================================

however, when executing curl from the command line, this output:

Do you use a proxy on your network? If so, make sure the relevant settings in macports.conf are correct.

Replying to ryandesign@…:

No, there is no proxy involved. In fact, the macports selfupdate command works just fine.

[ryandesign (Ryan Carsten Schmidt)]

selfupdate uses rsync; here we're talking about http.

[richard@…]

so, rsync works, curl works, and there is no proxy involved.

why does http not work, then?; and what exactly is the command that's used to connect and retrieve a distro? that is, i can test the command directly from the command line when i know what it is.

[ryandesign (Ryan Carsten Schmidt)]

MacPorts uses the curl library libcurl, not the curl executable, so it's not so straightforward to say what the corresponding command is. But if you can download the file with curl on the command line, it's not clear why you wouldn't be able to download the same file with MacPorts using libcurl.

Can’t reproduce, and no response in nearly 2 years.
