From my basic knowledge I’m wondering if we could just ASSERT if you attempt to grow the hash key read pool if its not a positive integer. As it happens, I ran in to this same exact problem last week, and it hasn’t recurred since I fixed my file locking mechanism to actually, you know, prevent concurrent writes. There must be an extra byte or two in the original that is triggering the behaviour but where Thank you very much for you indepth analysis and I’ll be sure to follow up if I can record a dump of the data structure that caused it in the first place. This value could be anything from billion.

I applied the following debugging patch: You can also delete the 7 bytes of session. Thank you very much for you indepth analysis and I’ll be sure to follow up if I can record a dump of the data structure that caused it in the first place. PerlMonks graciously bestowed by Tim Vroom. I have identified the errors in the file. You can also note the.
So that is my hint. We can all do without it randomly crashing. Check out past polls. Thus the problem is not really with the reading side per se, the data was actually written corruptly. Hi Matt, You up you are quite possibly right about the cause. As noted it looks like a buffer and offset issue.
Anyway these 4 bytes of data are where our 4 billion comes from.
Small Corrupted Storable Retrieve Dies With an Invalid “Out of memory!”
Without a test case data structure it is ;erl looking for a very small haystack in an enormous pile of needles! Also we have the same two bytes 06 F5 after session and. This RLEN macro reads an integer from the Storable file that specifies the size of the next data chunk to be read. How do I use this?
PerlMonks went on a couple dates, and then decided to shack up with The Perl Foundation.
If it does croak you can capture the raw data structure that causes the problem. I actually grew up in Omaha and attended school at the University of Nebraska at Omaha. It could be that there are no missing bytes as I speculated above but that it is simply a locking issue as you suggest. You will also note that problem occurs at an offset of bytes.
As it happens, I ran in to this same exact problem last week, and it hasn’t recurred since I fixed my file locking mechanism to actually, you know, prevent concurrent writes. Here is the text from my bug report: This immediately identifies a problem profile that needs fixing but more importantly it will give you a test case data structure.
On the subject of why the file gets corrupted, I recommend looking for file-locking bugs in the code that’s calling Storable:: It may be possible to debug it without this test case but it would be a lot easier if you have at least one problem data structure to validate the patch against.
In fact if you get delete the Others about the Monastery: If don’t have a 5. Anyway the integer is 0 x F5 06 6E 6F Looking at the datafile with a hex editor we see: I’ve pulled Storable 1.
I presume you worked your way through it with a hex editor as I don’t see how you could have done it with a regex. A storable file happens to be a user profile gets corrupted somehow and when I attempt to retrieve it, I get an “Out of memory!
Hey, saw you nick figured it was a football reference.
