Assetic:Dump --watch creates broken assetic_watch file on Windows #176

Running "assetic:dump" works, but when i try to use "assetic:dump --watch" after some time it will generate the following error:

Notice: unserialize(): Error at offset 0 of 25019 bytes in D:\vendor\symfony\
assetic-bundle\Symfony\Bundle\AsseticBundle\Command\DumpCommand.php line 96

Clearing cache or running assetic:dump does not fix this problem.

I found out that deleting a file called "assetic_watch_876b12e" in C:\Users\%NameOfWindowsUserHere%\AppData\Local\Temp does fix the problem.

The contents of the file when the file is broken is a whole lot of spaces, most likely the size of the serialized array would be.

After i deleted the file in the local temp directory and ran "assetic:dump --watch" again it refreshes the file it contains a serialized array of assets.

I don't know when it exactly happends, but it has happened multiple times over the past months on different windows machines. I think it is best to add a Try and catch on the unserializing part, and consider the file as non existing if it cannot be unserialized.


Same problem under ubuntu... solved by deleting the analogous file under /tmp folder


Just for all the people that copy your path into Windows+R, this on will work: %LOCALAPPDATA%\Temp. Or the whole command:

del "%LOCALAPPDATA%\Temp\assetic_watch_*"
