( #3333=superdoc: print w/replies, xml ) Need Help??
Here is the code I was using that is now broken. I have defined $dbh as a global variable using 'our' pragma.
if (my $pid = fork) { l("D","$restr [$tbn] [se_id:$se->{scenario_exec_id}] forking ($p +id) $se->{suite_name}:$se->{scenario_name}"); $V{scenario_exec_childs}->{$se->{scenario_exec_id}}{pid} = $pid; $V{scenario_exec_childs}->{$se->{scenario_exec_id}}{start_time} += $before_exec; # prepopulate before next cycle for state consistency, $se is re +ferenced in the $ses array ref in main loop $se->{status} = "RUNNING"; set_scenario_exec_state($se,{ -testbed_id=>$tb_id, -pid=>$pid, - +start=>"now()", status=>"RUNNING" }); sleep 2; } elsif (defined $pid) { $0 = "$restr $tbn SE:$se->{scenario_exec_id}"; l("D", "top of se fork: " . $dbh); # once and for all, I think I have figured out the forking + DBI + connection handling issue! 2007-04-23, # we clone the handle, undef it, then copy over the old variable + in the new process # suppress warning from clone call... I think something is broke +n with DBI # produces: Can't set DBI::db=HASH(0x82cf704)->{User}: unrecogni +sed attribute or invalid value at # /volume/perl/lib/site_perl/5.8.5/i386-freebsd/DBI.pm line 648. my $saved_warn_handler = $SIG{__WARN__}; $SIG{__WARN__} = sub {} +; my $child_dbh = $dbh->clone(); $SIG{__WARN__} = $saved_warn_hand +ler; l("D", "cloned child_dbh: " . $child_dbh); $dbh->{InactiveDestroy} = 1; undef $dbh; $dbh = $child_dbh;

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
