Corrupted file (most often when it is too big)

Hello,

I use Flexicontent 3.0 RC and Joomla 3.4.x.

I encountered a problem with files download (not related to 3.0 RC because it happened before, since many time).
For me and many users, file download works good, no problem.

But I have some users that can't download certain files, essentially if they are too big (> 100 mo).
If I try to download these files, it works for me.

I asked an user to send me the corrupted file (PDF) to see the problem. The file is corrupted, I open it with notepad++ to match the error message, but I can't find anything.
I have read many topics here that mentionned this bug (this topic for example : www.flexicontent.org/forum/9-support/520...comme-corrompus.html ) but it don't help me :unsure:
And it's difficult to debug it because for me all is working :silly:

Here are the txt of a corrupted pdf file (only the firsts lines) an user send me.


I can give you admin access (Joomla, FTP, phpmyadmin...) if you want to see the bug.

Thank in advance.

Bye.

Hello

you said you opened the corrupted file

so there is no PHP warning or notice at the begining and at the end of the file ?

Hello ggppdk, thank for your reply.

For the firsts lines, you can see them in the attach file above.

I look at the end of the file and I see this :

Hello

the message does not say what happened, instead it says that the error is inside web server log
-- by looking at the server log you will probably find what is happening

Guessing:
I guess the maximum PHP execution time is exhausted

Test this fix:
Edit file:
components/com_flexicontent/controller.php

After: add:
Also you could try to increase: max_execution_time of all scripts

Also (not related to your issue), v3.0.2 has been released

In the error logs, I have many errors of this type :

(9)Bad file descriptor: failed to stat user mapfile, referer: http://www......html

(104)Connection reset by peer: FastCGI: comm with server "/homez.742/xxxxx/www/index.php" aborted: read failed, referer:

Handler for fastcgi-script returned invalid result code 1, referer: http://www........html

They happen only on certains IP. I don't know if this is linked to file download bug.

I'll try your php code and I'll be back. Thank

I have installed FC 3.0.2, very nice features added ! Thank for all.

Hello

ok the file read is aborted , but it does not say why,

please try the fix suggested above regarding the max execution, to see if it corrects the issue

Hello

the above will probably not work, because we already have:

if ( !FLEXIUtilities::funcIsDisabled('set_time_limit') ) @set_time_limit(0);

you may try asking your web-host provider to help

we are doing 2 things, to allow large downloads
- try to set no execution limit (the statement above)
- we do not read the file into memory because we want to avoid memory exhausted errors,
instead we read it in parts via a lopp and send it to the user's browser

try downloading the file via a downloads manager and set into the manager a slow speed e.g. 50 Kbytes / sec, does the download corrupt ?

I'm waiting for my users replies about this bug if your fix correct it or not.
For me, all is working so I have to wait them

One user say me that he can download the above corrupted file, so it seems to be working, but I prefer to have others replies before concluding it is OK.

It seems not working finally

Is the user connexion can cause the corrupt file ? If the user have a slow connexion to Internet for example.

try downloading the file via a downloads manager and set into the manager a slow speed e.g. 50 Kbytes / sec, does the download corrupt ?

Which download manager ? :huh:

you may try asking your web-host provider to help

What can I say to them in order that they correct the bug ? I know nearly nothing in server config.

Thank again

Hello

you missed a later response, yes we had the code already

about download test, just send me a PM with a link and i will make this test,

the purpose of the test is to determine if a slow connection will cause some timeout on the server side
