Title:
dbExpand.pl outputs records in non-deterministic order
Status in EPICS Base:
Triaged
Status in EPICS Base 7.0 series:
Triaged
Bug description:
This concerns only the 7.0 branch since in 3.15 there is no
dbExpand.pl.
The observed non-determinism makes it hard to compare (diff) generated
db files if DB_OPT has been set in a Makefile.
The solution is simple, at the cost of making the procedure slightly
less efficient:
diff --git a/modules/database/src/tools/DBD/Output.pm b/modules/database/src/tools/DBD/Output.pm
index 869b485..55051df 100644
--- a/modules/database/src/tools/DBD/Output.pm
+++ b/modules/database/src/tools/DBD/Output.pm
@@ -118,8 +118,7 @@ sub OutputBreaktables {
sub OutputRecords {
my ($out, $records) = @_;
- foreach my $name (sort(keys %$records)) {
- my $rec = $records->{$name};
+ while (my ($name, $rec) = each %{$records}) {
next if $name ne $rec->name; # Alias
printf $out "record(%s, \"%s\") {\n", $rec->recordtype->name, $name;
printf $out " alias(\"%s\")\n", $_
Note: other output routines inside this module are similarly non-
deterministic in their output, but they are not used by dbExpand.pl.
