simple progress bar in my script Can't Post
i have an upload script with about 8 images and it can take up to 5 minutes of uploading and the user has no idea whats going on.
could somebody help me put a code into this script to show some sort of loading. even if its just
image 1 loaded
image 2 loading
image 2 loaded

and so on
here is my script







Code
#!/strawberry/perl/bin/perl -w  
  
  
  
use CGI::Carp qw( fatalsToBrowser );  
   
#print "Content-Type: text/html\n\n";  
#print "Content-Type: text/plain\n\n";  
#print "Content-Type: text";

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
I am not sure anyone will want to answer to your post containing 500 lines of poorly formatted code (why do you have such long lines in some places, up to 5 differents instructions and 182 characters long?), wrongly indented, all in one single chunk of code without even one single function (sub-routine) or one loop (except for reading a file), with lots of duplicated code, and filled with at least a dozen of gotos, making it really difficult to follow the logical execution path of your code.

You should really improve your coding practices. Use functions and loops, use lists, arrays and hashes, remove all the gotos, don't make lines longer that 80 characters or so, indent your code properly, use meaningful variable names, etc.

Uh, and read Damian Conway's "Perl best Practices".

i know my coding is poor but it does work ok.
could you explain why, when i put print"image1 loading";
and print"image2 loading"; inbetween uploading the images it does not display untill the very end and just shows all the prints .

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
Hi,

If you do not have new line characters, your output will be buffered (i.e. kept in memory and printed at a later point). Change

Code
print"image1 loading";
to

Code
print"image1 loading \n";
That should do the trick if you just want to print a message such as "image1 loading".

If that is not sufficient, you can set $| to a true value (1, for example), this will disable buffering and force an immediate a flush after every write or print on the output being used (STDOUT in this case).

i tried the print"loading \n"; but no joy.
how would i implement this
"you can set $| to a true value (1, for example),"

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
u need to change the perl buffer variable to 1 its the variable $| it will dump everything rather then hold the data to print out in a buffer and prints when print is invoked.. if that doesnt work then a javascript bar might work im sure u can find a free one.

Then, the print statements are probably not at the right place.

And that would not surprise me so much, given the mess of your program.

i have put the print commands in the for loop but i am still not getting the desire results, i am getting the results at the end of the script,

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
Hi,

I don't see how this printing would be buffered. This should work.

Possibly it is not the download of the images which is taking a lot of time, but some other part of your code.

I think you should time the whole thing.

One first approach is to change your code like this:

Code
# ... 
for my $i (1..8) {  
        my $date = gmtime(time); 
        print "$date : Uploading Image $i \n";  
	my $filename = $query->param("uploadfile$i");  
        # ...
Maybe you'll find out that the upload is actually faster than you think and that the program is spending a lot of time somewhere else.

In which case you should pour more of these performance profiling prints.

Note that there are a number of good profiling modules on the CPAN, but it won't work so long as you don't use functions to structure your code.

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
Strange, your output seems to indicate that you don't have the "\n" in your print statement, because each print should be on a new line, you should get something like this:

Code
Sat Aug 18 18:10:51 2012 : Uploading Image 1  
Sat Aug 18 18:10:57 2012 : Uploading Image 2  
Sat Aug 18 18:11:02 2012 : Uploading Image 3

You don't need to use subroutines to be able to profile scripts, but this script is so poorly written it's not even worth spending the time to profile it.

IMO, it should be thrown out and completely rewritten.

if i was as good as you i would be able to do that, but this is as good as i get for the minute :(
im learning as i go along as i only got into programming a few months ago really.
but as i progress the better the scripts will look.
do you have any pointers apart from "it should be thrown out"

Re: [Laurent_R] simple progress bar in my script [In reply to] Can't Post
ok i was using this command at the top of the script
print "Content-Type: text/html\n\n";
i have now replaced it for
print "Content-Type: text/plain\n\n";
and the output is better but still all at once

Re: [gerble1000] simple progress bar in my script [In reply to] Can't Post
Here are a few recommendation to start with.

Get rid of all of the goto statements. In there place, you should be using either an if/else construct, or call a subroutine, or a combination of both.

You're intermixing the functional and OO interface of the CGI module. Don't do that. Use one or the other, but not both.

Using the @skip and @result arrays don't make any sense and only serve to obfuscate the code. Instead, load all of your params in a hash, which only takes a singe line of code to accomplish. Or, if you must, use the param method to assign them to individual vars and use var names that indicate what they hold, such as using var names that match the field names.

The field name for all of the upload fields should be the same which allows you to easily put then into an array which you loop over when uploading.

I don't know what you're trying to accomplish with outputting each of the @bulletins fields to individual files, but I can assure you that you're using the wrong approach to accomplish that goal.

The resizing and corner rounding of the images can and probably should be done by using the proper CPAN module rather than doing the system calls.

Here's an example how your script should begin.
Code
#!/strawberry/perl/bin/perl 
 
use strict; 
use warnings; 
use CGI; 
use CGI::Carp qw( fatalsToBrowser warningsToBrowser ); 
use File::Copy; 
use File::Basename; 
use Image::Resize; 
 
$| = 1; 
$CGI::POST_MAX = 1024 * 50000; 
 
my $cgi = CGI->new; 
print $cgi->header, $cgi->start_html; 
warningsToBrowser(1); 
 
# this loads all of the submitted params into a hash 
# where the keys are the field names 
my %param = $cgi->Vars; 
 
# this is how to get the list of uploads 
# assuming they all had the same value for the 'name' attribute 
my @upload_files = split("\0", $param{'uploadfile'}); 
 
# this varname is a little verbose, but I know/understand where you got it 
my $safe_filename_characters = "a-zA-Z0-9_.-";

Re: [FishMonger] simple progress bar in my script [In reply to] Can't Post
thank you this is great.
my script runs 100x faster not sure why though,
and it prints on every upload which is great,
but it doesn't seem to use the \n as it just scrolls across the screen,
also i like the sound of this here
my @upload_files = split("\0", $param{'uploadfile'});

unsure how to use it as when i try to print the
$upload_files[0] i don't get anything onscreen to show that it has the parameter .
or is this a different kind of array

Since the doctype is html, you need to use the <br> html tag instead of (or in addition to) using \n.

Did you make the respective change to the form? Meaning, did you change the name attribute on the file upload fields so that they are all using the same value, or are they still numbered?

So, you're saying that it doesn't print the filenames, but it does upload the files?

Please post your updated script and the html form.

Re: [FishMonger] simple progress bar in my script [In reply to] Can't Post
my bad, i forgot to refresh the html page, works lovely :)
im going to have a play and use the same technique for the other paramaters,
what does this actually do
my %param = $cgi->Vars;
oh and does the "0" in this line start the array at [0]
my @upload_files = split("\0", $param{'uploadfile'});
if so could i start it at 1 like this
my @upload_files = split("\1", $param{'uploadfile'});

I told you that the problem was probably elsewhere. Your program was probably spending huge amount of time doing stupid and useless tasks repeteadly, but it was so poorly structured, that I certainly would not want to try understanding its behavior.

Never, ever, write a goto in Perl, this is really *bad* (except perhaps in very very specific cases for a very special flavor of goto, which has to do with Perl's black magics and nothing to do with the type of code you are writing).
