Re: pecl and the pear installer

Hi Greg and folks, I tried to install the fresh pecl_http-0.10.0 through pear, which oddly failed at a point of the package.xml which I was quite used to use. In this version I introduces PHP dependencies, and I usually require one version while recommendin another one with the following dependencies entry in package.xml: <deps> <dep type="php" rel="ge" version="4.3.1" optional="no" /> <dep type="php" rel="ge" version="5.0.4" optional="yes" /> </deps> I wonder because I've many PEAR packages specifying such dependencies and those worked well with PEAR-1.4 as far as I can tell. s1-iw:~# pear -V PEAR Version: 1.4.0a12 PHP Version: 4.3.10-15 s1-iw:~# peardev upgrade HTTP_Download WARNING: channel "pear.php.net" has updated its protocols, use "channel-update pear.php.net" to update Did not download dependencies: pear/HTTP_Header, pear/Archive_Zip, use --alldeps or --onlyreqdeps to download automatically pear/HTTP_Download can optionally use package "pear/Archive_Zip" downloading HTTP_Download-1.1.0RC2.tgz ...

And where does the "<= 6.0.0" dependency come from?

You have a package2.xml probably generated using pear convert with an older version of PEAR 1.4.0. The best thing to do is to go inside the package2.xml and find the dependencies section: <dependencies> ... <php> <min>5.0.4</min> <max>6.0.0</max> </php> ... </dependencies> (ellipses [...] represent other stuff you shouldn't change, in case I'm being unclear) and change it to: <dependencies> ... <php> <min>4.3.10</min> <exclude>5.0.0</exclude> <exclude>5.0.1</exclude> <exclude>5.0.2</exclude> <exclude>5.0.3</exclude> </php> ... </dependencies> This will have the desired effect of excluding PHP 5.x versions that are not compatible, while allowing everything else. The optional="yes" stuff you're doing is a bit of a hack, at best. If those PHP versions may be fine, but are not recommended, then documentation is the place to inform the user. In other words, use package.xml to prevent the user from shooting themselves in the foot (and to reduce duplicate bogus bugs :), but use docs for any gray areas. Hope this is helpful, let me know if I missed the point. Greg
