When web server OS is 32bit, then results of crc32 functions are positive and negative numbers in range, that fits nicely in "signed int" column in MySQL database.
However, when web server OS is 64bit, then same crc32 function produces only positive numbers (internally converts negative results to positive, not by removing sign from them) producing number is no longer fits into "signed it" range and will fit only in:
- unsigned int
- signed/unsigned bigint
Since we can't guess what architecture of web server, that will run In-Portal, would be then we need to:
- convert all negative results of crc32 function to positive using
$positive_crc = printf('%u', $crc)code - make all db columns, that can store such numbers either "int unsigned" or "bigint"
In 5.2.0-B2 this was noticed after tag <inp2:st_ContentBlock name="logos"/> was executed and produced content block number was stored incorrectly resulting inability to save content block changes.
We have 54 places, where crc32 function is used (across all modules) and each place needs to be inspected.
