Hi!
I am using commons-vfs2 version 2.6.0 and able to make connections over IPv6.
IPv6 address has to be provided in square brackets.

Ok, checked the v2.2 code and the fix isn't yet present.

I am trying to setup an FTP connection to the IPv6 loopback address using
commons-vfs2 version 2.2 and commons-net v3.6.
I tried following URI'S: [ftp://[::1]|ftp://[:1]] and
[ftp://[0:0:0:0:0:0:0:1]|ftp://[::1]/] but I am allways getting the error:
org.apache.commons.vfs2.FileSystemException: Invalid absolute URI
"[ftp://[0:0:0:0:0:0:0:1]|ftp://[::1]/]
Isn't the fix present in v2.2 or am I missing something here?

How about a fresh PR on Githubwith tests ;-)
I just pushed out version 2.2 but there is no reason not to have a 2.2.1 around
the corner.

Bernd Eckenfels commented on VFS-524:
-
I think parsing is only half the work, the URLs should also be created with [].
This testcase here should work (using a named interface scope and a non-default
port):
{code}
name = (GenericFileName) urlParser.parseUri(null, null,
"ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330%em4]:/test;);
assertEquals("2002:9ba:b4e:6:a052:5792:c0c9:2330%em4",
name.getHostName());
assertEquals(, name.getPort());
assertEquals("ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330%em4]:/test;,
name.getURI());
{code}
getURI() could skip the brackets when it does not need port or scope, but I
think adding it in all cases is better. I think it should not be returned by
getHostName() (even when it makes the thing more complicated).

The RFC 3986 [RFC 3986|http://tools.ietf.org/html/rfc3986] defines the usage
of IPv6 adresses inside of brackets [].

The uri include ipv6 address can't be parsed out correctly

Key: VFS-524
URL: https://issues.apache.org/jira/browse/VFS-524
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Reporter: Alex
Fix For: 2.1
I am using apache commons vfs2 to read and download file in ipv6 enviroment,
but it seems can't parse out ipv6 address correctly
The URI is just like:
ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test
The error message:
Invalid absolute URI ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test;.
Caused by : Expecting / to follow the hostname in URI
ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test;.
Deep into the code, I found the root cause is that HostFileNameParser's
extractHostName can't parse out the host name correctly
{noformat}
/**
* Extracts the hostname from a URI. The scheme://userinfo@ part has
* been removed.
*/
protected String extractHostName(final StringBuilder name)
{
final int maxlen = name.length();
int pos = 0;
for (; pos maxlen; pos++)
{
final char ch = name.charAt(pos);
if (ch == '/' || ch == ';' || ch == '?' || ch == ':'
|| ch == '@' || ch == '' || ch == '=' || ch == '+'
|| ch == '$' || ch == ',')
{
break;
}
}
if (pos == 0)
{
return null;
}
final String hostname = name.substring(0, pos);
name.delete(0, pos);
return hostname;
}
{noformat}
From the code, we are able to know it will parse out the host name by colon,
but for ipv6, it will get a wrong host name
There is the same problem with the other protocol like sftp and cifs

I make some fix in order to the method into parse out ipv6, for ftp, it works
well
So could I fix FtpFileNameParser to overrides the extractHostName of
HostFileNameParser? I am not sure whether it will bring in some problems else?
Thanks a lot
The uri include ipv6 address can't be parsed out correctly

Key: VFS-524
URL: https://issues.apache.org/jira/browse/VFS-524
Project: Commons VFS
Issue Type: Bug
Affects Versions: 2.0
Reporter: Alex lee
Fix For: 2.1
I am using apache commons vfs2 to read and download file in ipv6 enviroment,
but it seems can't parse out ipv6 address correctly
The URI is just like:
ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test
The error message:
Invalid absolute URI ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test;.
Caused by : Expecting / to follow the hostname in URI
ftp://[2002:9ba:b4e:6:a052:5792:c0c9:2330]/test;.
Deep into the code, I found the root cause is that HostFileNameParser's
extractHostName can't parse out the host name correctly
{noformat}
/**
* Extracts the hostname from a URI. The scheme://userinfo@ part has
* been removed.
*/
protected String extractHostName(final StringBuilder name)
{
final int maxlen = name.length();
int pos = 0;
for (; pos maxlen; pos++)
{
final char ch = name.charAt(pos);
if (ch == '/' || ch == ';' || ch == '?' || ch == ':'
|| ch == '@' || ch == '' || ch == '=' || ch == '+'
|| ch == '$' || ch == ',')
{
break;
}
}
if (pos == 0)
{
return null;
}
final String hostname = name.substring(0, pos);
name.delete(0, pos);
return hostname;
}
