Progress bar does not appear/update

[mnapoli]

Thank you for the report. Have you ever used Symfony? I am using the Console's progress bar, nothing (I think) out of the ordinary here.

If you have time maybe you could try to write a small script with a progress bar using only Symfony to see if it's a problem there or in Bref?

Hello,

No problem. I tried that, and the progress bar worked as expected. I just tried the default, plain Symfony bar (as shown in the image). That seems to be working fine using this script.

require __DIR__.'/vendor/autoload.php';

use Symfony\Component\Console\Helper\ProgressBar;
use Symfony\Component\Console\Output\ConsoleOutput;
use Symfony\Component\Console\Formatter\OutputFormatter;

$output = new ConsoleOutput();
$output->setFormatter(new OutputFormatter(true));

echo "Starting ...\n";

// creates a new progress bar (20 units)
$progressBar = new ProgressBar($output, 20);

// starts and displays the progress bar
$progressBar->start();

$i = 0;
while ($i++ < 20) {
    sleep(1);

   $progressBar->advance();
}

// ensures that the progress bar is at 100%
$progressBar->finish();

echo "\nDone!\n";```

Thank you for trying all that! I'm thinking 2 things could cause the issue:

• I overloaded the progress character: $progressBar->setBarCharacter('░'); https://github.com/mnapoli/bref/blob/master/src/Console/Deployer.php#L213
• I output stuff above the progress bar while it is being re-rendered: https://github.com/mnapoli/bref/blob/master/src/Console/Deployer.php#L88-L90

If you still have your script around maybe you could try with $progressBar->setBarCharacter('░');?

Ah, that could be it.

I tried again with that progress bar character, and the bar was invisible. The '>' was still at the end, and that did progress, but perhaps your formatting removes that.

When I tried another character, like:
$progressBar->setBarCharacter('*');
... it worked, and the bar filled (in my test code anyway). So what I might do is try editing your code locally to overwrite that line, try a deploy, and see if I see a bar. If so, it is that character that's causing it.

Hello,

Yes, changing the character made the bar appear. I tried a * but I guess any ASCII would do.

However - and this may be to do with what the progress bar is monitoring - it doesn't update during an upload. It (and the time) does not change. It only seems to reflect the steps completed. Perhaps that is how it is meant to work, treating each step as taking an equal time. But since the upload of the Lambda, the last bit, is by far the slowest bit of the process (for me on my connection anyway!), I would find it helpful if a/the bar monitored the upload progress (as in X MB/Total MB).

I've changed the characters so that it works on Ubuntu too (I reverted back to Symfony's default style).

As for the progress it is very hard to use serverless' progress, I won't work on it but feel free to do so and send a PR if you want to.
