The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

seems like it did know it was corrupted.


No, the code had a bug whereby it "took too long" to read a value/token. I have fixed the bug so now the value/token gets read and returned and then the caller can determine whether or not the value is reasonable.

failing a million times


No, not failing a million times, failing once.

jschell wrote:
the architecture indicates that it is not in general corrupted


In general, yes, non-ASCII characters cannot be considered invalid by the reader, only the caller can determine that.
A large text value may contain a few non-ASCII characters, such as "smart quotes", and that's fine. The issue was that when a value which contains many non-ASCII characters, it took too long to read -- it also happens that the value was corrupt in this case.

jschell wrote:
Corrupted generally would refer to some random process.


Yes, and we still don't know what is causing the corruption.

jschell wrote:
random process might create a character that passes your checks (regardless of how you check) but still represent bad data


As is always the case, and again the reader can't determine that.

jschell wrote:
some other bad data would end up being accepted as good.


As is always the case, and again the reader can't determine that.

In this particular case of corruption, the process will fail when it tries to stuff a million-plus characters into a database column which allows only two-hundred. But yes, even now there may be a file on the way which is corrupt in such a way that the bad value fits and the load won't fail. The reader won't care, the loader won't care, but some other part of the process will (probably) freak out.
