From: Lady Date: Sun, 28 Apr 2024 03:06:06 +0000 (-0400) Subject: Don’t allow network or DTD loading X-Git-Tag: 0.7.3~1 X-Git-Url: https://git.ladys.computer/Shushe/commitdiff_plain/a17c5cb8e0cef1d871cdf0b476d00831ce07b6e7?ds=inline;hp=ccef2f2a2243cf086b165562cb73defa14f34f62 Don’t allow network or DTD loading This still processes the internal DTD in a nonvalidating way. Formerly, it would try to fetch the XML catalog DTD every time. --- diff --git a/GNUmakefile b/GNUmakefile index bbf15d7..da2912d 100644 --- a/GNUmakefile +++ b/GNUmakefile @@ -264,7 +264,7 @@ override ensuredirectory = if $(TEST) ! -d $(call quote,$1); then $(MKDIR) -p $( override xpath = $(XMLLINT) --xpath $(call quote,$1) $(call quote,$2) > /dev/null 2> /dev/null # (callable) Extract the value of the text nodes in the provided X·M·L document and print them to `stdout´. -override extracttext = $(PRINTF) '%s' '' | $(XSLTPROC) -
