Updating perl modules

Cuando terminamos de indicar todos los cambios a realizar, los ejecutamos con el icono de la flecha verde hacia la derecha (Ctrl Enter) Tendremos que confirmarlos junto con las dependencias a instalar/actualizar que los módulos seleccionados necesiten.Para iniciar PPM en modo consola, abrimos una y tipeamos: ┌────────────┬─────────┬───────┬─────────┬──────┐ │ name │ version │ files │ size │ area │ ├────────────┼─────────┼───────┼─────────┼──────┤ │ DBD-CSV │ 0.38 │ 3 │ 31 KB │ perl │ │ DBD-ODBC │ 1.31 │ 9 │ 329 KB │ perl │ │ DBD-Oracle │ 1.58 │ 22 │ 636 KB │ perl │ │ DBD-Pg │ 2.19.3 │ 8 │ 2035 KB │ perl │ │ DBD-SQLite │ 1.37 │ 9 │ 6205 KB │ perl │ │ DBD-mysql │ 4.022 │ 13 │ 2963 KB │ site │ └────────────┴─────────┴───────┴─────────┴──────┘ (6 packages installed matching 'dbd') El formato de salida depende de la cantidad de paquetes que se encuentren con el patrón.Oh, and if you’re not familiar with CVS, don’t worry. Just copy the commands that I prepared for you and you’re good to go: Pkgsrc 2007Q2 bootstrap complete! We just need to adjust the path variable so that the system picks up binaries from the new paths (and make those take precedence over the old system binaries).We could just change the PATH variable but it’s better to make the changes persistent. This is what we currently have: We’re on 4.11-RELEASE. This old release has a very old port for subversion but that’s fair enough.Remember: Free BSD 4.11 was released in 2005 – however the ABI of each release is carved in stone with a .0 release.Which means that the software in the base system is from 4.0 and thus we venture back into the last millenium: 1999! Doing a little research, I found out that this directory used to be part of the OS and was removed in early Free BSD 5 as it was mostly redundant with /rescue. Have a look yourself: # ls /stand -sh etc minigzip rm tunefs [ find mount_mfs route usbd arp fsck mount_nfs rtsol usbdevs boot_crunch gunzip newfs sed zcat camcontrol gzip pccardc sh cpio help pccardd slattach dhclient hostname ppp sysinstall dhclient-script ifconfig pwd test# sockstat -4 -l USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS root dhclient 281 7 udp4 *:68 *:* root sendmail 84 4 tcp4 *:25 *:* root sendmail 84 6 tcp4 *:587 *:* root sshd 75 4 tcp4 *:22 *:* root syslogd 61 5 udp4 *:514 *:* to deactivate any daemons except for SSH (which we need). Pkgsrc is basically Net BSD’s fork of the Free BSD ports tree.

En la ventana que se abre podremos buscar módulos a partir de su nombre (cambiando “::” por “-“) en las vistas de Todos, Instalables y Actualizables.

To give you an idea what this means, here are a few program versions: Various program’s versions in 4.11’s base system So we have these programs among others: GCC 2.95.4 Binutils 2.12.1 Perl 5.0 Open SSH 3.5 To make matters worse, the ports tree for Free BSD 4.11 is pretty dead, too. This may not be strictly necessary but we want to improve the security of this system, right? I’ll connect to the 4.11 box remotely over SSH because it’s much more convenient to have my trusty terminal at hand and to be able to copy and paste stuff: . Being a Net BSD project however, it’s not limited to just Net BSD.

It’s important to get newer compilers running, but around 2005 Free BSD used special releases to build GCC from (“gcc-core”) and I was not able to find a single mirror on the net that still holds those old and exotic files! And I wouldn’t trust those crusty old daemons at all. Free BSD 4.11 with most daemons disabled If you reboot now, sendmail and syslogd as well as cron, usbd and inetd will be disabled. It’s a truely portable way of building and managing software (I might write a separate post about it some time).

This can be useful when a variable is bound to a sub-routine or object method which you want to call but aren't interested in the value returned.

Variables may be assigned the values of other variables, unquoted numbers (2.718), literal text ('single quotes') or quoted text ("double quotes").
