As I said in my response to David, I can do just the open, and see that there is no lock, and do the same open in another session without error. > 2) try to reproduce it prefixing the command with ltrace -tt Well, as you say below, no Xapian references. Even worse, ltracing the Tcl version sees no Notmuch references either. > 3) examine carefully the ltrace logs to figure out where the proble lies So all I can see is that the notmuch_database_open from notmuch new looks just like I think mine would look - if I could see it. (Adding -S to ltrace was not particularly informative either.) > Tomi > > Hmm, Interestingly when I run > > LD_LIBRARY_PATH=~/vc/ext/notmuch/lib ltrace -f -tt > ~/vc/ext/notmuch/notmuch-shared new > > I did not see any Xapian references, but when I did > > ltrace -f -tt ~/vc/ext/notmuch/notmuch new > > I did. Interestingly when using libnotmuch.so.4 the xapian interface > is hidden (is it baked inside ~/vc/ext/notmuch/lib/libnotmuch.so.4.3.0 :O) My latest piece of evidence suggests that this may not be a Notmuch problem, because opening a Xapian database via the Xapian-Tcl bindings results in: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME cat 2803 eric 5w REG 8,9 0 526601 /home/eric/omega/data/newsgroups/flintlock No lock here either (and this is not even a Notmuch database).
