Summary: PF/runtime: find_qn_bulk() adds new qnames twice
Initial Comment:
If I compile and run the query
BugTracker/nested_element_construction.SF-1712578.xq with the algebra version
(pf -A) I get a merged_union error which boils down to duplicate entries in the
qname relations. The reason are the following two lines from find_qn_bulk() in
pf_support.mx which both modify the same relation:
1.188 (stmane 10-Jan-07):
qn_prefix_uri_loc.append(_pref_uri_loc, true);
1.195 (sjoerd 20-Feb-07): ws.fetch(QN_PREFIX_URI_LOC +
UPDATE).find(cont).insert(_pref_uri_loc);

If I run the test
tests/BugTracker/Tests/nested_element_construction.SF-1712578_alg, I get no
differences. So what is the problem then?
If the problem is what you describe in your comment about add_qnames
behaving differently than [add_qname], then that could perhaps be a
different bug. I don't immediately see how that relates to find_qn_bulk,
which is what the bug was originally about.
In other words, if this is a new bug, please use a new bug report, if it
is the same bug but in a different guise, please elaborate, and if there is
no bug, then please close this report.

This bug seems to be open again.
module ("pathfinder");
var ws := ws_create ();
var a := bat
(void,str).seqbase([EMAIL
PROTECTED]).append("foo").append("foo").append("foo").append("bar").append("bar").append("bar");
var b := add_qnames(a.project (""), a.project (""), a, ws);
print(ws.fetch(QN_LOC).fetch(0));
#-----------------#
# h t # name
# oid str # type
#-----------------#
[ [EMAIL PROTECTED], "foo" ]
[ [EMAIL PROTECTED], "bar" ]
[ [EMAIL PROTECTED], "foo" ]
[ [EMAIL PROTECTED], "bar" ]
Whereas the following snippet does the correct thing:
var b := [add_qname](a.project (""), a.project (""), a, CONST ws);
#-----------------#
# h t # name
# void str # type
#-----------------#
[ [EMAIL PROTECTED], "foo" ]
[ [EMAIL PROTECTED], "bar" ]

finishing Peter'\''s fix of find_qn_bulk():
the new code used "if (update) ...",
while the function'\''s signature read "... bit add ...";
this caused about 20 tests to fail with
"!ERROR: unknown variable '\''update'\''."
fixed by renaming the parameter "add" to "update"
(the latter indeed seems more intuitive/descriptive than the former).
this makes the ~20 failing tests work, again.
test added in
pathfinder/tests/BugTracker/Tests/nested_element_construction.SF-1712578_alg.*
