Downloading large files with Cocoon 2.1.5 + Tomcat 4.1.24
Hi,
We need to store large files (>30MB) in a database (MS SQL). The upload
seems to work, because we've compared the filesize in db to the actual
file. But when downloading, browser (IE or Mozilla) does not succeed. IE
saves 0 bytes to disk, and Mozilla doesn't even start the download
process.
We're using the modular DatabaseAddAction for upload, and the
DatabaseReader for download.
I did another test, and tried to get Cocoon to return a large zip-file
(>30MB) with the default file reader, and it didn't work either! Has
anyone tried to return any large sources with Cocoon lately?
Any help would be great, running out of ideas and time here... :(
-Tuomo

Thank you Bruno! :)
It definitely did the trick. I remember having this working about a year
ago, without that parameter. Has the pipeline implementation changed
since, therefore requiring this parameter?
Thanks again,
Tuomo

Put your pipelines in a map:pipeline element like:
<map:pipeline type="noncaching">
<map:parameter name="outputBufferSize" value="8192"/>

The sad thing is that, in the meantime other changes have been made to
the same source causing merge conflicts.
The longer it takes for a committer to apply the patch, the harder it
will be to actually do it.
For my project I simply copied the existing ResourceReader into
BetterResourceReader, applied the patch and stopped using the original
ResourceReader. Not perfect because now I'm missing the latest code
changes but at least my large files work OK.

On this wiki page is a reference to a bug which has a patch to fix it
attached. There are 40 bugs in the 'zilla which contain the word patch
and are in the NEW state. Whats the policy on getting these looked at?
Thanks,
andy
PS one of them is mine... Bug id: #28973.

There's no real policy: whenever a committer has either a) enough free
time or b) a big enough itch to scratch, they will look at the patch
and eventually commit it.
Looking at the relatively low activity on this list these days, it
seems like a) is fairly scarce at the moment. If you think you patch
might qualify for b), you might want to remind us here of why you think
so.

On this wiki page is a reference to a bug which has a patch to fix it
attached. There are 40 bugs in the 'zilla which contain the word patch
and are in the NEW state. Whats the policy on getting these looked at?
