Summary0002465: DC silently produces broken ZIP when packing file of size >4G
DescriptionWhen DC creates a ZIP file using internal ZIP plugin
and the file being packed is larger than > 4G (I tried
file of size 4 383 401 125 B), then the ZIP file is
broken. Worse, any indication of the problem is not
presented to the user during packing process. Only when
user tries to unpack that ZIP file (does not matter which
app is used to unpacking), the error message is displayed
and unpacked data are corrupted.
Steps To ReproduceTo reproduce: Select file with size > 4G; press Alt+F5;
select "zip" packer (configuration: method = smDeflated,
option = doNormal).
Additional InformationThis is a data corruption problem. Worse, a silent one.
I have made a backup of important data by packing using
DC zip and believed that I am safe. When I have deleted
all other copies, I found my backup was corrupted.
Surprise. I recommend to give high priority to this bug.
TagsNo tags attached.
