From aeab1e959d1fb383a0ff21924bff0edd01404fab Mon Sep 17 00:00:00 2001
From: jbj <devnull@localhost>
Date: Tue, 9 Nov 1999 20:57:38 +0000
Subject: fix: typo in error message (#6858). tufdio.c: Create. rpmurl.h: Add
 ctrl, data, buf, and bufAlloced to urlinfo. UFDSANE assertion. rpmio.h: Add
 fdWritable(), fdReadable(), fdRdline(), exported (for now) to          ftp.c
 checkResponse(). ftp.c: checkResponse() rewritten to use above. ftp.c:
 checkResponse() handles html in 501 response on closed http connection.
 ftp.c: ftpCommand() rewritten to simplify (using stpcpy). ftp.c: httpOpen()
 now reopens time-out persistent connection. ftp.c: Get rid of O_NONBLOCK
 reads, not necessary AFAICT. ftp.c: ftpFileDesc() uses u->data rather than
 passed in fd arg. Use a consistent refcounting scheme to achieve persistent
 malloc and open ctrl. query.c: get ready for Remglob(). rpmio.c: ftpCmd()
 functional (using tufdio).
