Changelog
Daniel (21 January 2005)
- Major FTP third party transfer overhaul.
These four options are now obsolete: CURLOPT_SOURCE_HOST,
CURLOPT_SOURCE_PATH, CURLOPT_SOURCE_PORT (this option didn't work before)
and CURLOPT_PASV_HOST.
These two options are added: CURLOPT_SOURCE_URL and CURLOPT_SOURCE_QUOTE.
The target-side didn't use the proper path with RETR, and thus this only
worked correctly in the login path (i.e without doing any CWD). The source-
side still uses a wrong path, but the fix for this will need to wait. Verify
the flaw by using a source URL with included %XX-codes.
Made CURLOPT_FTPPORT control weather the target operation should use PORT
(or not). The other side thus uses passive (PASV) mode.
Updated the ftp3rdparty.c example source to use the updated options.
Added support for a second FTP server in the test suite. Named... ftp2.
Added test cases 230, 231 and 232 as a few first basic tests of very simple
3rd party transfers.
Changed the debug output to include 'target' and 'source' when a 3rd party
is being made, to make it clearer what commands/responses came on what
connection.
Added three new command line options: --3p-url, --3p-user and --3p-quote.
Documented the command line options and the curl_easy_setopt options related
to third party transfers.
(Temporarily) disabled the ability to re-use an existing connection for the
source connection. This is because it needs to force a new in case the
source and target is the same host, and the host name check is trickier now
when the source is identified with a full URL instead of a plain host name
like before.
TODO (short-term) for 3rd party transfers: quote support. The options are
there, we need to add test cases to verify their functionality.
TODO (long-term) for 3rd party transfers: IPv6 support (EPRT and EPSV etc)
and SSL/TSL support.
Daniel (20 January 2005)
- Philippe Hameau found out that -Q "+[command]" didn't work, although some
code was written for it. I fixed and added test case 227 to verify it.
