Fixed. > I ignored the warning and tested the .netrc support. It didn't work > correctly. If I just enter the hostname without the username, MC > should still find the username in .netrc instead of logging in as > "anonymous". That would be consistent with the command line ftp client. Fixed (the problem was vfs_split_url() in utilvfs.c, which would always return "anonymous" as a username if none was specified in the URL, no matter whether "use_netrc" was set in ~/.mc/ini or not). Now, if there are multiple login/password entries in ~/.netrc for the same host, and you don't enter a login name at all (ie. ftp://host/), login and password will be picked from ~/.netrc on a first-match-wins basis. As a consequence, you'll have to explicitly add "anonymous" or "ftp" to the URL as a login name now if you want anonymous FTP to a host listed in ~/.netrc. OTOH, if there are multiple login/password entries for the same host, and you *do* enter a login name, only the corresponding password will be picked from ~/.netrc. > Also it seems to me from the name of the third argument to > login_server(), "netrcpass", that the password from .netrc should be > determined earlier and sent to login_server(). Fixed (it is now determined in open_archive(), if use_netrc is set). > First of all, it's not trivial. I don't know if anybody noticed, but > I didn't. Sorry if I came across like a complete jerk. I meant that my fix (ok, make that "quick & dirty hack" ;-) was trivial, as in "almost *too* easy, too good to be true". And I certainly didn't wonder why "nobody was able to fix that trivial problem" or why "nobody noticed that trivial fix for the problem", I only wondered why nobody noticed for such a long time that there was a problem with ~/.netrc handling at all. > If you want to clean it up, please do, but don't ignore warnings and > test your patch. Done. I tried to keep changes to the original code at a minimum, and #ifdef'd the stuff I added where possible. There should be no changes when compiled without #define USE_NETRC. The patch applies cleanly to the latest snapshot (mc-2002-04-26-21), and compiles without warnings. Multiple different login/password entries for the same host also work as expected (or at least as *I* would expect them to work ;-). Enabling and disabling ~/.netrc lookups (via use_netrc in ~/.mc/ini) works fine as well. I haven't had a look at the menu code in boxes.c yet, though, so you still have to edit ~/.mc/ini manually. Again, sorry if my original mail came across too rude, it really wasn't meant that way, and I certainly didn't mean to offend anyone working on MC.
