[yast-devel] LD_PRELOAD doesn't work for processes running as root any more

JFYI - this might affect us, too, at least for debugging or testing. If there was an announcement anywhere else, I missed it.

[yast-devel] new YCP builtins
by Arvin Schnell 05 Jun '08

05 Jun '08

Hi YCP-Hackers, I've used some ITO time to implement two new YCP builtins: 1. splitlist (var x, list, block using x) Takes a list and a predicate function and splits the list where the predicate function says so. Returns a list of lists. Example: list<string> l = [ "0", "a", "1", "2", "b", "3", "4" ]; splitlist(string s, l, { return isalpha(s); }); return is [ [ "0" ], [ "a", "1", "2" ], [ "b", "3", "4" ] ] The difference to splitstring is that the 'delimiter' is included in the result since that's the way I need it. If desired I could add a parameter that tells whether the 'delimiter' should be added to the previous list, the following list or not at all. 2. reducelist (var x, var y, initial value, list, block using x and y) This is the standard reduce function known from Lisp (but also available in e.g. C++, Python and Ruby). It takes a list and reduces it to a single value by applying a function, see: http://en.wikipedia.org/wiki/Reduce_%28higher-order_function%29 Examples: // sum and product integer sum = reducelist(integer x, integer y, 0, [ 1, 2, 3, 4 ], { return x + y; }); integer product = reducelist(integer x, integer y, 1, [ 1, 2, 3, 4 ], { return x * y; }); // min and max list<integer> l1 = [ 1, 2, 3 ]; integer min = reducelist(integer x, integer y, l1[0]:nil, l1, { return x < y ? x : y; }); integer max = reducelist(integer x, integer y, l1[0]:nil, l1, { return x > y ? x : y; }); // mergestring list<string> l2 = [ "hello", "openSUSE", "world" ]; string s = reducelist(string x, string y, "", l2, { return x + " " + y; }); // find longest string string ls = reducelist(string x, string y, "", l2, { return size(x) > size(y) ? x : y; }); // find length of longest string (note: type of x and y differ) integer ll = reducelist(integer l, string s, 0, l2, { return size(s) > l ? size(s) : l; }); Patch is attached. Still missing is documentation and testsuite. The patch contains a binary incompatibility to libycp by adding the clear() function to YCPList. If that's not wanted a workaround is included (maybe someone has a better workaround). Bytecode compatibility is not touched. It's not possible to add the functions to a module since they use the variable type feature of YCP. Please comment. ciao Arvin -- Arvin Schnell, <aschnell(a)suse.de> Software Engineer, Research & Development SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg)

[yast-devel] yast2-devtools requires cvs package
by Michal Zugec 03 Jun '08

03 Jun '08

Hi all! yast2-devtools from trunk still requires cvs nevertheless we already use subversion. It's not only rpm dependency but also some scripts: fgrep -r " cvs " *|grep -v svn|cut -d':' -f1|sort -u devtools/admin/Makefile.am.toplevel devtools/admin/po/Makefile.am.center devtools/bin/devtools-migration devtools/doc/html/index.html devtools/doc/yast2-devtools-section.xml devtools/doc/yast2-devtools.sgml Makefile Makefile.am Makefile.in package/yast2-devtools.changes yast2/freshdoc yast2/freshdoc.conf ydoc/po-tools/needed_modules Please replace cvs with proper svn from your scripts, otherwise I'll do that next week ;-) Thank you, Michal -- Best Regards, Michal Zugec Software developer --------------------------------------------------------------------- SuSE CR, s.r.o. e-mail: mzugec(a)suse.cz Lihovarska 1060/12 tel: +420 284 028 960 190 00 Praha 9 fax: +420 296 542 374 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: yast-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: yast-devel+help(a)opensuse.org
