"Find more Extensions" and install in configure is installing each file listed in the MANIFEST twice.

before configure, Find more extensions:

www-data@r17311:~/community.reefsimple.org/foswiki$ svn status | grep -v cgisess | grep -v 'igp_'
?      working/work_areas/AttachContentPlugin
?      pub/Trash
?      data/Trash/.changes
?      data/Main/.changes
?      data/System/.changes
?      data/Sandbox/.changes

after configure, Find more extensions:

www-data@r17311:~/community.reefsimple.org/foswiki$ svn status | grep -v cgisess | grep -v 'igp_'
?      working/work_areas/AttachContentPlugin
?      pub/Trash
?      pub/System/GoogleAnalyticsPlugin
?      templates/foswiki.googleanalytics.tmpl.bak
?      templates/foswiki.googleanalytics.tmpl
?      lib/Foswiki/Plugins/GoogleAnalyticsPlugin.pm.bak
?      lib/Foswiki/Plugins/GoogleAnalyticsPlugin.pm
M      data/log200905.txt

Confirmed for a 1.0.5 with a test installation of PersonalInfoAddOn.

NOTE that this is for a fresh installation, and that there should be no .bak files generated yet (this is not a re-install or upgrade).

It very much depends what you did during the run of configure. if you installed the same extension twice, you'll get .bak files. Need to be more specific about what the problem is, here, please.

-- CrawfordCurrie - 26 May 2009

i'm painfully aware that .bak files are created when you already have an extension installed. as i say above, this was for a fresh installation (first time the extension was installed), and therefore there should be no backup files generated. not sure what additional information you want, i've already placed a lot of information on this page.

did you even try to install a new extension and see if .bak files were generated?

Because the extension installer is designed to install packages that don't have installer scripts, such as those packaged for twiki using zip, it downloads and unpacks the package before looking for the installer script, and running it if it finds one. The installer scripts were designed to be runnable from the command line, and do a "pull" install by downloading the package. So this is what was happening; EXTEND was downloading and unpacking, and then the installer script was downloading and unpacking again. D'oh.
