Recipe 21.7 Upgrading PEAR Packages
21.7.1 Problem
You
want to upgrade a package on your system to the latest version for
additional functionality and bug fixes.
21.7.2 Solution
Find out if any upgrades are available and then tell
pear to upgrade the packages you want:
% pear list-upgrades
% pear upgrade Package_Name
21.7.3 Discussion
Upgrading to a new version of a package is a simple task with the
PEAR Package Manager. If you know a specific package is out of date,
you can upgrade it directly. However, you may also want to just
periodically check to see if any new releases are available.
To do this, user the
list-upgrades command, which prints out a
table showing package names, the new version number, and the size of
the download:
% pear list-upgrades
Available Upgrades (stable):
= == == == == == == == == == == == == == =
+-------------+---------+--------+
| Package | Version | Size |
| Archive_Tar | 0.9 | 8.9kB |
| Auth | 1.0.2 | 8.8kB |
| Auth_HTTP | 1.0.1 | 1.7kB |
| DB | 1.3 | 58kB |
| HTTP | 1.1 | 2.9kB |
| Mail | 1.0.1 | 11.6kB |
| Mail_Mime | 1.2.1 | 15.0kB |
| Net_Ping | 1.0.1 | 2.1kB |
| Net_SMTP | 1.0 | 2.8kB |
| Net_Socket | 1.0.1 | 3.5kB |
| PEAR | 0.9 | 40kB |
| XML_Parser | 1.0 | 4.8kB |
| XML_RPC | 1.0.3 | 11.9kB |
| XML_RSS | 0.9.1 | 3.1kB |
| XML_Tree | 1.1 | 4.7kB |
+-------------+---------+--------+
If you're up to date, pear
prints:
No upgrades available
To upgrade a particular package, use the
upgrade command. For example:
% pear upgrade DB
downloading DB-1.3.tgz ...
...done: 59,332 bytes
The short command for list-upgrades is
lu; for upgrade
it's up.
PEAR also has an RSS feed listing new packages available at
http://pear.php.net/rss.php.
