Subject: tool_urlglob: support globs as long as config line lengths
X-Git-Tag: rc-8_18_0-2~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28d27570fa021011b8679344d090772fea49d0d1;p=thirdparty%2Fcurl.git

tool_urlglob: support globs as long as config line lengths

libcurl supports up to 8MB string inputs, the config file accepts up to
10MB line lengths. It did not make sense to limit the globs to a maximum
of one megabyte.

Closes #19960
