Well, how are you supposed to serialize an enum value without some sort
of numerical representation or value? Maybe you could serialize it by
converting the enum to a string representation of its name but that
wouldn't be efficient and also if a developer refactored its code base
and renamed an enum, when unserializing the data it wouldn't be properly
assigned. Also other languages don't force you to assign value for an
enum constants, if I recall correctly languages like C/C++ automatically
assing an interger value to enumerations in they order they were typed so:
enum BadDays {MONDAY, SUNDAY, THURSDAY=5, SATURDAY}
would be MONDAY = 0, SUNDAY = 1, THURSDAY=5, SATURDAY=6
So assigning a value is optional.
I see the enum's rfc mentions boxing primitive types but that seems to
not solve what I'm saying here at all.
Enums should be a nice way of grouping constant values without hitting
on the performance (for everything else use a class). The rfc is
proposing a nice syntax but it doesn't fully covers
serialization/unserialization of enumerations.

Well I never have worked on a JIT/AOT and I have to admit I haven't done any contributions to the PHP engine (and it seems I do not have any rights to write some couple of messages expressing concerns/views because of that). On the other side I took the wxwidgets extension in an effort to revive it (because I believe PHP can have other use cases). Improved its code generator (and other stuff that involved a relation with the PHP source code) which now generates more than 905941 lines of code that constitute the extension (github.com/wxphp/wxphp/tree/master/src). So I have indeed read source from PHP core. In any case, sorry if I have annoyed some, that never was my intention, we as humans can't posses all the knowledge of the world, so thats why we always learn from somebody else, whats the purpose of a community without participation :) Cheers! -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] RFC: Replacing errors with Exceptions
I published a (work in progress) RFC today about replacing certain errors with exceptions. I know that there already was something similiar on the php6dev blog, but this is not completly the same, so awating your comments: http://wiki.php.net/rfc/errors_as_exceptions -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DEV] PHP broken pipe in fork
The child process doesn't use any database connection, just to run some shell scripts, but it closes the connection anyway. I initialy used PEAR DB and then _pconnect functions but the result is the same. Was the bug solved two years ago ? How was it solved ?

Error writing data to the connection. Broken pipe] That would be a fairly well known issue with PHP. You're running into the same thing we encountered about 2 years ago. What happens is that your child process is closing the mysql connection as part of its standard PHP cleanup procedures, leaving the parent with a broken connection. I'd recommend provisioning a method so that your child makes its own new connection, and does not use the parent's connection at all. Since all php scripts clean up before exiting, you need to make sure all resources in use by the child are not needed by the parent after the child exits. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] PHP broken pipe in fork
Hi, i'm using firebird 1.5.1 on a linux machine with a php script I'm using a query in loop and go through all records to do some operations in the middle of the script i fork(); to do other things When i return to the parent process i try to make one update and i get the following error [nativecode=Unable to complete network request to host "127.0.0.1". Error writing data to the connection. Broken pipe] And continue the loop of the records of the query. It apears that the fork and the wait from pcntl closes the sockets to the database. Is this a regular beaviour ? How can it be solved ? I'm using Pear DB for database access.
