Improve parsing of certain FTP directory listing formats (#2408)#2409
Merged
Conversation
…#2408) This surgical fix restricts parsing to the input buffer when the listing entry date in "TypeA" or "TypeB" formats is not followed by a filename. It does not improve rendering of listings with missing filenames or the overall quality of FTP listing parsing code. C strchr() always returns a non-nil pointer when given a NUL character, so its callers must be careful not to supply a NUL character if a "natural" one-of-the-regular-c-string-characters membership test is required. The bug was probably introduced in 1997 commit 3fdadc7 and then duplicated in 2017 commit 3d87209.
