![]() Zendframework/zend-session suggests installing zendframework/zend-cache (Zend\Cache component) Zendframework/zend-session suggests installing mongodb/mongodb (If you want to use the MongoDB session save handler) Installing theseer/fdomdocument (1.6.6) I am definitely using the same user account to do the upgrade as was used to install Magento so I don’t think it’s a permissions uncated lots of updates. It seems to work nicely upgrading all the files but then it seems to stop (as if it has actually finished) but I get the following and the file bin/magento has completely gone. I am using these commands: cd /var/-no-update Setup multiple domain with Apache2 with nf VirtualHost Examples - DevOpsSchool.I am tying to upgrade a Magento 2.1 site to Magento 2.2.0 but it seems to be dropping out during the process and the bin/magento file is removed but not replaced so nothing at all works after this.SandraKnox on PunBB modification – Implementing iconized categories for forum topics.Whilst a Crptographicall Secure Pseudo Random number Generator is recommended for generating UUIDs, I’d hedge a bet that if you were to make up the UUIDS for a database of 100M entries yourself from imagination alone, we’d be pretty safe against clashes ? This means that 1 trillion UUIDs would have to be created every nanosecond for slightly more than 10 billion years to exhaust the number of UUIDs. The number of theoretically possible UUIDs is therefore 216*8 = 2128 = 25616 or about 3.4 Ã- 1038. As security holes go, md5 clashes receive rather more press than they deserve.Ī UUID (wikipedia) is a 16-byte (128-bit) number. Made more concise using features of recent PHP for the heads up, but the poster at php.net has fundametally misunserstood what a hash collision is or means – a hash collision is where the chances of finding two different input strings which produce the same hash are reduced enough to (arguably, in theory only) warrant implementing the vast computing power necessary to do so, and offers no guarantees as to the clashing string’s usefulness in any security context. UPDATE: The method of getting random string changed based on Davids comment. UPDATE : The PHP Universal Feed Generator class, for which I wrote this function is released. ![]() In its canonical form, a UUID consists of 32 hexadecimal digits, displayed in 5 groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters. ![]() This means that 1 trillion UUIDs would have to be created every nanosecond for 10 billion years to exhaust the number of UUIDs. Let’s take a look what Wikipedia has to say about the format of UUID :Ī UUID is a 16-byte (128-bit) number. I’ve use the standard of canonical format here. Then I wrote the following function to generate it. I searched the web for a simple solution but didn’t find any that suffices my need. When I was writing the RSS Writer class for Orchid, I needed to generate UUID to implement with ATOM id. Universally Unique Identifier is an identifier standard which is used in a varieties of software construction.
