Tracking down +the script that caused the error is a pain. This fixes that. Replace +the usual + + use Carp; + +with + + use CGI::Carp + +And the standard warn(), die (), croak(), confess() and carp() calls +will automagically be replaced with functions that write out nicely +time-stamped messages to the HTTP server error log. + +For example: + + [Fri Nov 17 21:40:43 1995] test.pl: I'm confused at test.pl line 3. + [Fri Nov 17 21:40:43 1995] test.pl: Got an error message: Permission denied. + [Fri Nov 17 21:40:43 1995] test.pl: I'm dying. + +=head1 REDIRECTING ERROR MESSAGES + +By default, error messages are sent to STDERR. Most HTTPD servers +direct STDERR to the server's error log. Some applications may wish +to keep private error logs, distinct from the server's error log, or +they may wish to direct error messages to STDOUT so that the browser +will receive them. + +The C<carpout()> function is provided for this purpose. Since +carpout() is not exported by default, you must import it explicitly by +saying + + use CGI::Carp qw(carpout); + +The carpout() function requires one argument, which should be a +reference to an open filehandle for writing errors. It should be +called in a C<BEGIN> block at the top of the CGI application so that +compiler errors will be caught. Example: + + BEGIN { + use CGI::Carp qw(carpout); + open(LOG, ">>/usr/local/cgi-logs/mycgi-log") or + die("Unable to open mycgi-log: $!\n"); + carpout(LOG); + } + +carpout() does not handle file locking on the log for you at this point. + +The real STDERR is not closed -- it is moved to SAVEERR. Some +servers, when dealing with CGI scripts, close their connection to the +browser when the script closes STDOUT and STDERR. SAVEERR is used to +prevent this from happening prematurely. + +You can pass filehandles to carpout() in a variety of ways. The "correct" +way according to Tom Christiansen is to pass a reference to a filehandle +GLOB: + + carpout(\*LOG); + +This looks weird to mere mortals however, so the following syntaxes are +accepted as well: + + carpout(LOG); + carpout(main::LOG); + carpout(main'LOG); + carpout(\LOG); + carpout(\'main::LOG'); + + ... and so on + +FileHandle and other objects work as well. + +Use of carpout() is not great for performance, so it is recommended +for debugging purposes or for moderate-use applications. A future +version of this module may delay redirecting STDERR until one of the +CGI::Carp methods is called to prevent the performance hit. + +=head1 MAKING PERL ERRORS APPEAR IN THE BROWSER WINDOW + +If you want to send fatal (die, confess) errors to the browser, ask to +import the special "fatalsToBrowser" subroutine: + + use CGI::Carp qw(fatalsToBrowser); + die "Bad error here"; + +Fatal errors will now be echoed to the browser as well as to the log. CGI::Carp +arranges to send a minimal HTTP header to the browser so that even errors that +occur in the early compile phase will be seen. +Nonfatal errors will still be directed to the log file only (unless redirected +with carpout). + +=head2 Changing the default message + +By default, the software error message is followed by a note to +contact the Webmaster by e-mail with the time and date of the error. +If this message is not to your liking, you can change it using the +set_message() routine. This is not imported by default; you should +import it on the use() line: + + use CGI::Carp qw(fatalsToBrowser set_message); + set_message("It's not a bug, it's a feature!"); + +You may also pass in a code reference in order to create a custom +error message. At run time, your code will be called with the text +of the error message that caused the script to die. Example: + + use CGI::Carp qw(fatalsToBrowser set_message); + BEGIN { + sub handle_errors { + my $msg = shift; + print "<h1>Oh gosh</h1>"; + print "Got an error: $msg"; + } + set_message(\&handle_errors); + } + +In order to correctly intercept compile-time errors, you should call +set_message() from within a BEGIN{} block. + +=head1 CHANGE LOG + +1.05 carpout() added and minor corrections by Marc Hedlund + <hedlund@best.com> on 11/26/95. + +1.06 fatalsToBrowser() no longer aborts for fatal errors within + eval() statements. + +1.08 set_message() added and carpout() expanded to allow for FileHandle + objects. + +1.09 set_message() now allows users to pass a code REFERENCE for + really custom error messages. croak and carp are now + exported by default.

Although CGI::Cookie is +intended to be used in conjunction with CGI.pm (and is in fact used by +it internally), you can use this module independently. + +For full information on cookies see + + http://www.ics.uci.edu/pub/ietf/http/rfc2109.txt + +=head1 USING CGI::Cookie + +CGI::Cookie is object oriented. Each cookie object has a name and a +value. The name is any scalar value. The value is any scalar or +array value (associative arrays are also allowed). Cookies also have +several optional attributes, including: + +=over 4 + +=item B<1. expiration date> + +The expiration date tells the browser how long to hang on to the +cookie. If the cookie specifies an expiration date in the future, the +browser will store the cookie information in a disk file and return it +to the server every time the user reconnects (until the expiration +date is reached). If the cookie species an expiration date in the +past, the browser will remove the cookie from the disk file. If the +expiration date is not specified, the cookie will persist only until +the user quits the browser. + +=item B<2. domain> + +This is a partial or complete domain name for which the cookie is +valid. The browser will return the cookie to any host that matches +the partial domain name. For example, if you specify a domain name +of ".capricorn.com", then Netscape will return the cookie to +Web servers running on any of the machines "www.capricorn.com", +"ftp.capricorn.com", "feckless.capricorn.com", etc. Domain names +must contain at least two periods to prevent attempts to match +on top level domains like ".edu". If no domain is specified, then +the browser will only return the cookie to servers on the host the +cookie originated from. + +=item B<3. path> + +If you provide a cookie path attribute, the browser will check it +against your script's URL before returning the cookie. For example, +if you specify the path "/cgi-bin", then the cookie will be returned +to each of the scripts "/cgi-bin/tally.pl", "/cgi-bin/order.pl", +and "/cgi-bin/customer_service/complain.pl", but not to the script +"/cgi-private/site_admin.pl". By default, path is set to "/", which +causes the cookie to be sent to any CGI script on your site. + +=item B<4. secure flag> + +If the "secure" attribute is set, the cookie will only be sent to your +script if the CGI request is occurring on a secure channel, such as SSL. + +=back + +=head2 Creating New Cookies + + $c = new CGI::Cookie(-name => 'foo', + -value => 'bar', + -expires => '+3M', + -domain => '.capricorn.com', + -path => '/cgi-bin/database' + -secure => 1 + ); + +Create cookies from scratch with the B<new> method. The B<-name> and +B<-value> parameters are required. The name must be a scalar value. +The value can be a scalar, an array reference, or a hash reference. +(At some point in the future cookies will support one of the Perl +object serialization protocols for full generality). + +B<-expires> accepts any of the relative or absolute date formats +recognized by CGI.pm, for example "+3M" for three months in the +future. See CGI.pm's documentation for details. + +B<-domain> points to a domain name or to a fully qualified host name. +If not specified, the cookie will be returned only to the Web server +that created it. + +B<-path> points to a partial URL on the current server. The cookie +will be returned to all URLs beginning with the specified path. If +not specified, it defaults to '/', which returns the cookie to all +pages at your site. + +B<-secure> if set to a true value instructs the browser to return the +cookie only when a cryptographic protocol is in use. + +=head2 Sending the Cookie to the Browser + +Within a CGI script you can send a cookie to the browser by creating +one or more Set-Cookie: fields in the HTTP header. Here is a typical +sequence: + + my $c = new CGI::Cookie(-name => 'foo', + -value => ['bar','baz'], + -expires => '+3M'); + + print "Set-Cookie: $c\n"; + print "Content-Type: text/html\n\n"; + +To send more than one cookie, create several Set-Cookie: fields. +Alternatively, you may concatenate the cookies together with "; " and +send them in one field. + +If you are using CGI.pm, you send cookies by providing a -cookie +argument to the header() method: + + print header(-cookie=>$c); + +Mod_perl users can set cookies using the request object's header_out() +method: + + $r->header_out('Set-Cookie',$c); + +Internally, Cookie overloads the "" operator to call its as_string() +method when incorporated into the HTTP header. as_string() turns the +Cookie's internal representation into an RFC-compliant text +representation. You may call as_string() yourself if you prefer: + + print "Set-Cookie: ",$c->as_string,"\n"; + +=head2 Recovering Previous Cookies + + %cookies = fetch CGI::Cookie; + +B<fetch> returns an associative array consisting of all cookies +returned by the browser. The keys of the array are the cookie names. You +can iterate through the cookies this way: + + %cookies = fetch CGI::Cookie; + foreach (keys %cookies) { + do_something($cookies{$_}); + } + +In a scalar context, fetch() returns a hash reference, which may be more +efficient if you are manipulating multiple cookies. + +CGI.pm uses the URL escaping methods to save and restore reserved characters +in its cookies. If you are trying to retrieve a cookie set by a foreign server, +this escaping method may trip you up. Use raw_fetch() instead, which has the +same semantics as fetch(), but performs no unescaping. + +You may also retrieve cookies that were stored in some external +form using the parse() class method: + + $COOKIES = `cat /usr/tmp/Cookie_stash`; + %cookies = parse CGI::Cookie($COOKIES); + +=head2 Manipulating Cookies + +Cookie objects have a series of accessor methods to get and set cookie +attributes. Each accessor has a similar syntax. Called without +arguments, the accessor returns the current value of the attribute. +Called with an argument, the accessor changes the attribute and +returns its new value. + +=over 4 + +=item B<name()> + +Get or set the cookie's name. Example: + + $name = $c->name; + $new_name = $c->name('fred'); + +=item B<value()> + +Get or set the cookie's value. Example: + + $value = $c->value; + @new_value = $c->value(['a','b','c','d']); + +B<value()> is context sensitive. In an array context it will return +the current value of the cookie as an array. In a scalar context it +will return the B<first> value of a multivalued cookie. + +=item B<domain()> + +Get or set the cookie's domain. + +=item B<path()> + +Get or set the cookie's path. + +=item B<expires()> + +Get or set the cookie's expiration time. + +=back + + +=head1 AUTHOR INFORMATION + +be used and modified freely, but I do request that this copyright +notice remain attached to the file.

It is specialized to work well with the Open Market +FastCGI standard, which greatly speeds up CGI scripts by +turning them into persistently running server processes. Scripts +that perform time-consuming initialization processes, such as +loading large modules or opening persistent database connections, +will see large performance improvements. + +=head1 OTHER PIECES OF THE PUZZLE + +In order to use CGI::Fast you'll need a FastCGI-enabled Web +server. Open Market's server is FastCGI-savvy. There are also +freely redistributable FastCGI modules for NCSA httpd 1.5 and Apache. +FastCGI-enabling modules for Microsoft Internet Information Server and +Netscape Communications Server have been announced. + +In addition, you'll need a version of the Perl interpreter that has +been linked with the FastCGI I/O library. Precompiled binaries are +available for several platforms, including DEC Alpha, HP-UX and +SPARC/Solaris, or you can rebuild Perl from source with patches +provided in the FastCGI developer's kit. The FastCGI Perl interpreter +can be used in place of your normal Perl without ill consequences. + +You can find FastCGI modules for Apache and NCSA httpd, precompiled +Perl interpreters, and the FastCGI developer's kit all at URL: + + http://www.fastcgi.com/ + +=head1 WRITING FASTCGI PERL SCRIPTS + +FastCGI scripts are persistent: one or more copies of the script +are started up when the server initializes, and stay around until +the server exits or they die a natural death. After performing +whatever one-time initialization it needs, the script enters a +loop waiting for incoming connections, processing the request, and +waiting some more. + +A typical FastCGI script will look like this: + + #!/usr/local/bin/perl # must be a FastCGI version of perl! + use CGI::Fast; + &do_some_initialization(); + while ($q = new CGI::Fast) { + &process_request($q); + } + +Each time there's a new request, CGI::Fast returns a +CGI object to your loop. The rest of the time your script +waits in the call to new(). When the server requests that +your script be terminated, new() will return undef. You can +of course exit earlier if you choose. A new version of the +script will be respawned to take its place (this may be +necessary in order to avoid Perl memory leaks in long-running +scripts). + +CGI.pm's default CGI object mode also works. Just modify the loop +this way: + + while (new CGI::Fast) { + &process_request; + } + +Calls to header(), start_form(), etc. will all operate on the +current request. + +=head1 INSTALLING FASTCGI SCRIPTS + +See the FastCGI developer's kit documentation for full details. On +the Apache server, the following line must be added to srm.conf: + + AddType application/x-httpd-fcgi .fcgi + +FastCGI scripts must end in the extension .fcgi. For each script you +install, you must add something like the following to srm.conf: + + AppClass /usr/etc/httpd/fcgi-bin/file_upload.fcgi -processes 2 + +This instructs Apache to launch two copies of file_upload.fcgi at +startup time. + +=head1 USING FASTCGI SCRIPTS AS CGI SCRIPTS + +Any script that works correctly as a FastCGI script will also work +correctly when installed as a vanilla CGI script. However it will +not see any performance benefit. + +=head1 CAVEATS + +I haven't tested this very much. + +=head1 AUTHOR INFORMATION + +be used and modified freely, but I do request that this copyright +notice remain attached to the file.

It is +specialized for server push operations, which allow you to create +animated pages whose content changes at regular intervals. + +You provide CGI::Push with a pointer to a subroutine that will draw +one page. Every time your subroutine is called, it generates a new +page. The contents of the page will be transmitted to the browser +in such a way that it will replace what was there beforehand. The +technique will work with HTML pages as well as with graphics files, +allowing you to create animated GIFs. + +=head1 USING CGI::Push + +CGI::Push adds one new method to the standard CGI suite, do_push(). +When you call this method, you pass it a reference to a subroutine +that is responsible for drawing each new page, an interval delay, and +an optional subroutine for drawing the last page. Other optional +parameters include most of those recognized by the CGI header() +method. + +You may call do_push() in the object oriented manner or not, as you +prefer: + + use CGI::Push; + $q = new CGI::Push; + $q->do_push(-next_page=>\&draw_a_page); + + -or- + + use CGI::Push qw(:standard); + do_push(-next_page=>\&draw_a_page); + +Parameters are as follows: + +=over 4 + +=item -next_page + + do_push(-next_page=>\&my_draw_routine); + +This required parameter points to a reference to a subroutine responsible for +drawing each new page. The subroutine should expect two parameters +consisting of the CGI object and a counter indicating the number +of times the subroutine has been called. It should return the +contents of the page as an B<array> of one or more items to print. +It can return a false value (or an empty array) in order to abort the +redrawing loop and print out the final page (if any) + + sub my_draw_routine { + my($q,$counter) = @_; + return undef if $counter > 100; + return start_html('testing'), + h1('testing'), + "This page called $counter times"; + } + +You are of course free to refer to create and use global variables +within your draw routine in order to achieve special effects. + +=item -last_page + +This optional parameter points to a reference to the subroutine +responsible for drawing the last page of the series. It is called +after the -next_page routine returns a false value. The subroutine +itself should have exactly the same calling conventions as the +-next_page routine. + +=item -type + +This optional parameter indicates the content type of each page. It +defaults to "text/html". Normally the module assumes that each page +is of a homogenous MIME type. However if you provide either of the +magic values "heterogeneous" or "dynamic" (the latter provided for the +convenience of those who hate long parameter names), you can specify +the MIME type -- and other header fields -- on a per-page basis. See +"heterogeneous pages" for more details. + +=item -delay + +This indicates the delay, in seconds, between frames. Smaller delays +refresh the page faster. Fractional values are allowed. + +B<If not specified, -delay will default to 1 second> + +=item -cookie, -target, -expires + +These have the same meaning as the like-named parameters in +CGI::header(). + +=back + +=head2 Heterogeneous Pages + +Ordinarily all pages displayed by CGI::Push share a common MIME type. +However by providing a value of "heterogeneous" or "dynamic" in the +do_push() -type parameter, you can specify the MIME type of each page +on a case-by-case basis. + +If you use this option, you will be responsible for producing the +HTTP header for each page. Simply modify your draw routine to +look like this: + + sub my_draw_routine { + my($q,$counter) = @_; + return header('text/html'), # note we're producing the header here + start_html('testing'), + h1('testing'), + "This page called $counter times"; + } + +You can add any header fields that you like, but some (cookies and +status fields included) may not be interpreted by the browser. One +interesting effect is to display a series of pages, then, after the +last page, to redirect the browser to a new URL. Because redirect() +does b<not> work, the easiest way is with a -refresh header field, +as shown below: + + sub my_draw_routine { + my($q,$counter) = @_; + return undef if $counter > 10; + return header('text/html'), # note we're producing the header here + start_html('testing'), + h1('testing'), + "This page called $counter times"; + } + + sub my_last_page { + header(-refresh=>'5; URL=http://somewhere.else/finished.html', + -type=>'text/html'), + start_html('Moved'), + h1('This is the last page'), + 'Goodbye!' + hr, + end_html; + } + +=head2 Changing the Page Delay on the Fly + +If you would like to control the delay between pages on a page-by-page +basis, call push_delay() from within your draw routine. push_delay() +takes a single numeric argument representing the number of seconds you +wish to delay after the current page is displayed and before +displaying the next one. The delay may be fractional. Without +parameters, push_delay() just returns the current delay. + +=head1 INSTALLING CGI::Push SCRIPTS + +Server push scripts B<must> be installed as no-parsed-header (NPH) +scripts in order to work correctly. On Unix systems, this is most +often accomplished by prefixing the script's name with "nph-". +Recognition of NPH scripts happens automatically with WebSTAR and +Microsoft IIS. Users of other servers should see their documentation +for help. + +=head1 CAVEATS + +This is a new module.
