From 1c41ae5ae3d4816687467712580d5f05957b3b88 Mon Sep 17 00:00:00 2001 From: Nicolas Iooss Date: Thu, 6 Jul 2017 21:32:14 +0200 Subject: [PATCH] Use str:replace from exslt.org to implement string.subst string.subst implementation causes recursion issues when building systemd documentation. This issue has been reported in https:\/\/bugs.debian.org\/cgi-bin\/bugreport.cgi?bug=765567 and https:\/\/bugs.archlinux.org\/task\/54694 . A possible fix consists in using str:replace from exslt.org when this function is available. This has been implemented in a patch for the Debian package (https:\/\/anonscm.debian.org\/cgit\/collab-maint\/docbook-xsl.git\/tree\/debian\/patches\/765567_non-recursive_string_subst.patch) which has also been used by Arch Linux (https:\/\/git.archlinux.org\/svntogit\/packages.git\/tree\/trunk\/765567_non-recursive_string_subst.patch?h=packages\/docbook-xsl&id=c6bf4ebc446487043437ed13e4fbe83f648f5c58). Translate this patch to xsl\/lib\/lib.xweb in order to fix the recursion issues. For reference, here is the beginning of the error messages reported by xslt when building systemd: XSLT man\/systemd.directives.html Note: namesp. add : added namespace before processing systemd.directives runtime error: file file:\/usr\/share\/xml\/docbook\/xsl-stylesheets-1.79.2\/lib\/lib.xsl line 56 element variable xsltApplySequenceConstructor: A potential infinite template recursion was detected. You can adjust xsltMaxDepth (--maxdepth) in order to raise the maximum number of nested template calls and variables\/params (currently set to 3000).
