Hello Martin

Thanks for the quick reply and for the pointer to the appropriate code, that's 
great - I'll take a look at tweaking the limit in our local Galaxy if it 
continues to be a problem.

Best wishes

Peter

Subject: Re: [galaxy-dev] Enable viewing of large HTML files

Hi Peter,

I believe the 1MB is hard coded in 
https://github.com/galaxyproject/galaxy/blob/dev/lib/galaxy/managers/hdas.py#L222
 and cannot be configured.

That said you can change it on your instance, I have also opened an issue to 
allow configuring this value.

Dear Devs

We have a locally developed tool which takes in a collection of Fastq pairs and 
produces a number of outputs which includes a number of HTML files.

For relatively small numbers of input files all the HTML outputs can be viewed 
without issue in Galaxy. However we've observed that for large collections of 
Fastqs, the size of one of the HTML files can be very large (several megabytes) 
and by default attempting to view these in Galaxy results in the "This dataset 
is large and only the first megabyte is shown below" message, followed by the 
initial HTML markup rendered as text.

As clicking on the "show all" link renders the entire HTML file correctly, is 
there a way to force Galaxy to shortcut the truncation for HTML (or at least 
apply a larger limit for determining when files are too large to be shown all 
at once)?

We're currently using 17.05 in our production instance.

Thanks for advance for any help or suggestions,

Best wishes

Peter
