Erm... it looks you're debugging an old version then. The new codebase after http://mail.opensolaris.org/pipermail/onnv-notify/2009-February/008582.html uses libshell directly and no longer any isaexec stuff or /usr/bin/ksh93. > Finally > we open /bin/sleep but next I see a search through my > PATH for a file .paths (so sleep depends on NFS servers now) That will be fixed - see below for the webrev... > and shortly thereafter we open the name_service_door > (alarm bells to current discussion). That will by http://cr.opensolaris.org/~gisburn/ksh93_integration_cr_6807179_002/ , including a test suite module which explicitly tests for this condition to make sure we never see this again. > That won't eliminate issues such as the execname issue for pgrep, That was already fixed by http://mail.opensolaris.org/pipermail/onnv-notify/2009-February/008582.html > but we can confirm it's being about as honest and clean as > a shell script can be. Slightly offtopic: Do you know _any_ other issues which need to be fixed except those listed above (I really like to kill all bugs/complains now in "one go") ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;)
