# A boolean chart is a way of representing the terms in a logical
# expression. Bugzilla builds SQL queries depending on how you enter
# terms into the boolean chart. Boolean charts are represented in
# urls as tree-tuples of (chart id, row, column). The query form
# (query.cgi) may contain an arbitrary number of boolean charts where
# each chart represents a clause in a SQL query.
#
# The query form starts out with one boolean chart containing one
# row and one column. Extra rows can be created by pressing the
# AND button at the bottom of the chart. Extra columns are created
# by pressing the OR button at the right end of the chart. Extra
# charts are created by pressing "Add another boolean chart".
#
# Each chart consists of an arbitrary number of rows and columns.
# The terms within a row are ORed together. The expressions represented
# by each row are ANDed together. The expressions represented by each
# chart are ANDed together.
#
# ----------------------
# | col2 | col2 | col3 |
# --------------|------|------|
# | row1 | a1 | a2 | |
# |------|------|------|------| => ((a1 OR a2) AND (b1 OR b2 OR b3) AND (c1))
# | row2 | b1 | b2 | b3 |
# |------|------|------|------|
# | row3 | c1 | | |
# -----------------------------
#
# --------
# | col2 |
# --------------|
# | row1 | d1 | => (d1)
# ---------------
#
# Together, these two charts represent a SQL expression like this
# SELECT blah FROM blah WHERE ( (a1 OR a2)AND(b1 OR b2 OR b3)AND(c1)) AND (d1)
#
# The terms within a single row of a boolean chart are all constraints
# on a single piece of data. If you're looking for a bug that has two
# different people cc'd on it, then you need to use two boolean charts.
# This will find bugs with one CC matching 'foo@blah.org' and and another
# CC matching 'bar@blah.org'.
#
# --------------------------------------------------------------
# CC | equal to
# foo@blah.org
# --------------------------------------------------------------
# CC | equal to
# bar@blah.org
#
# If you try to do this query by pressing the AND button in the
# original boolean chart then what you'll get is an expression that
# looks for a single CC where the login name is both "foo@blah.org",
# and "bar@blah.org". This is impossible.

# BuildOrderBy - Private Subroutine
# This function converts the input order to an "output" order,
# suitable for concatenation to form an ORDER BY clause. Basically,
# it just handles fields that have non-standard sort orders from
# %specialorder.
# Arguments:
# $orderitem - A string. The next value to append to the ORDER BY clause,
# in the format of an item in the 'order' parameter to
# Bugzilla::Search.
# $stringlist - A reference to the list of strings that will be join()'ed
# to make ORDER BY. This is what the subroutine modifies.
# $reverseorder - (Optional) A boolean. TRUE if we should reverse the order
# of the field that we are given (from ASC to DESC or vice-versa).
#
# Explanation of $reverseorder
# ----------------------------
# The role of $reverseorder is to handle things like sorting by
# "target_milestone DESC".
# Let's say that we had a field "A" that normally translates to a sort
# order of "B ASC, C DESC". If we sort by "A DESC", what we really then
# mean is "B DESC, C ASC". So $reverseorder is only used if we call
# BuildOrderBy recursively, to let it know that we're "reversing" the
# order. That is, that we wanted "A DESC", not "A".
sub BuildOrderBy {
my ($orderitem, $stringlist, $reverseorder) = (@_);
my @twopart = split(/\s+/, $orderitem);
my $orderfield = $twopart[0];
my $orderdirection = $twopart[1] || "";
if ($reverseorder) {
# If orderdirection is empty or ASC...
if (!$orderdirection || $orderdirection =~ m/asc/i) {
$orderdirection = "DESC";
} else {
# This has the minor side-effect of making any reversed invalid
# direction into ASC.
$orderdirection = "ASC";
}
}
# Handle fields that have non-standard sort orders, from $specialorder.
if ($specialorder{$orderfield}) {
foreach my $subitem (@{$specialorder{$orderfield}}) {
# DESC on a field with non-standard sort order means
# "reverse the normal order for each field that we map to."
BuildOrderBy($subitem, $stringlist, $orderdirection =~ m/desc/i);
}
return;

push(@$stringlist, trim($orderfield . ' ' . $orderdirection));
