This object has methods that return the similarly named structure field name from the stat(2) function; namely, dev, ino, mode, nlink, uid, gid, rdev, size, atime, mtime, ctime, blksize, and blocks. X You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your stat() and lstat() functions.) Access these fields as variables named with a preceding C<st_> in front their method names. Thus, C<$stat_obj-E<gt>dev()> corresponds to $st_dev if you import the fields. X To access this functionality without the core overrides, pass the C<use> an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the C<CORE::> pseudo-package.

This object has methods that return the similarly named structure field name from the C's hostent structure from F<netdb.h>; namely name, aliases, addrtype, length, and addresses. The aliases and addresses methods return array reference, the rest scalars. The addr method is equivalent to the zeroth element in the addresses array reference. X You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding C<h_>. Thus, C<$host_obj-E<gt>name()> corresponds to $h_name if you import the fields. Array references are available as regular array variables, so for example C<@{ $host_obj-E<gt>aliases() }> would be simply @h_aliases. X The gethost() funtion is a simple front-end that forwards a numeric argument to gethostbyaddr() by way of Socket::inet_aton, and the rest to gethostbyname(). X To access this functionality without the core overrides, pass the C<use> an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the C<CORE::> pseudo-package.

Since _09 is going to be alpha anyway, I reiterate my question: Is there any reason to not include my hash/array performance patches in _09? Btw, here is the next performance patch. It makes PADTMP values stealable too.

* Re: "Attempt to free non-existent shared string"? (with patch)Gurusamy Sarathy1996-09-201-4/+6
| | | | | | | | | | | | I found a subtle problem with the lazydelete mechanism (which is used to postpone the delete of a entry that may be getting iterated over). I was using the HeKLEN slot to hold the hint, but the real HeKLEN is needed later to call unsharepvn(). This means that only magical hash entries can use the HeKLEN slot to hold flags. Here's a tested patch against 5.00305 that fixes the problem. The patch simply moves the LAZYDEL hint to become a SV-level private flag.
