Smarty

[adn]

Hi all,

I tried the new version 3.1.15 and I get a white page

If I desactivate the template cache and the cache, it works but not in the normal production mode. I have deleted all caches but nothing change.

Am I alone to get this problem? What could be the problem? How to debug as it works in debug mode?

check your php error log?

Hi mohrt,

With previous versions without emptying cache, new versions works, ascending compatibility was ok. But here not.

I did another quick test and nothing appears in my apache log

The problem is that I have no test environment. If I put the new lib in prod everything is down which is not really fine and for how long I don't know because no error appears.

An impacting modification is done in this version

I created a hidden mode to test and same result, a white page and no error in apache log. I didn't empty the cache. Should the cache 3.1.14 be compatible with 3.1.15 code?

OK with
$smarty->setCaching(FALSE);
$smarty->setCompileCheck(TRUE);
$smarty->setDebugging(TRUE);
$smarty->setMergeCompiledIncludes(TRUE);
$smarty->setUseSubDirs(TRUE);

KO with
$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
$smarty->setCompileCheck(TRUE);
$smarty->setDebugging(TRUE);
$smarty->setMergeCompiledIncludes(TRUE);
$smarty->setUseSubDirs(TRUE);

I did another test by emptying all the caches (compiled tpl and cache) , same result

I think there is a problem with this new version

Did you check also php error log or just apache log?

It's strange that you get a white page but no errors.

So it does work if you disable caching and does it also work with caching enabled and when debugging is true?

That was not clear from your previous posts.

[mohrt]

Anytime you upgrade you should empty compiled and cached data. Anything could change.

The php error log wasn't activated on my server, now done

My scenario

- tail -f of the php errors and httpd
- I re-upload smarty and re-transfert the libs folder.
- I empty the compiled templates
- I empty the cache

Still a white page

I added some traces and the problem appears somewhere in display() method.

If I put setCaching(FALSE) it is ok but ko with setCaching(Smarty::CACHING_LIFETIME_CURRENT)

The php error log file is absolutely empty, no error

Can you make please a test with caching enabled,
but $smarty->setMergeCompiledIncludes(FALSE);

You must manually delete the compiled templates after this change.

[mohrt]

Are you upgrading Smarty 2 to Smarty 3 by chance?

You can also test everything, see what you get:

$smarty->testInstall();

@moshrt,
From 3.1.14 to 3.1.15 and the testInstall with the 3.1.15 code is ok

@U.Tews,
I did a quick test with setMergeCompiledIncludes(FALSE) but without emptying the cache because I am in production and I guess I cannot mix the 2 solutions. The result is the same
To do the test I add an option in my url and then I use the new lib instead of the old one for this page.

For the test with setMergeCompiledIncludes(FALSE) it is necessary to delete existing compiled templates and cache files. Otherwise this test makes no sense

[adn]

Yes I understood but the problem is that this test put my website completely out! All pages become white, a nightmare

OK I tested setMergeCompiledIncludes(FALSE) and empty the compiled tpl folder manually. Nothing change, still white pages and still ok when I don't use the cache.

I just see that my page returns a 500 code in that case

What can generate this error code?
