#24 Downloading duplicity directly from duply

[Kamil(ek)]

Hi!

Firstly, thanks a lot for your great work with the duply. I am using it in a company, and it saves a lot of time and effort while doing backups.

However, I found it very frustrating when there is a need to install/upgrade duplicity and duply on dozens of different UNIX-like systems. I made a small addition to the duply which enables downloading and installation of duplicity. It is useful particularly when new version of duplicity is published, so there is no necessity to download/install package manually.

As I recently noticed, a download/install option is on duply TO-DO list, so maybe this one is what you need?
If you find it useful, consider adding it to the duply project.

Keep up the great work!

would you be willing to develop this further so that
1. it differs between root and ordinary users (users may not install to /usr but to ~), see http://duply.net/?title=Duply-documentation under TIP how to install it locally. i'd suggest to put it in ~/.duply/duplicity-<version>
2. make duply select local installed duplicity's before global ones in PATH
3. reuses duply TMP dir setting
4. use a temporary filename for the download (the file might already exist in TMP but created by a different user, hence unwritable)
5. implement it as command 'setup', ideally with a parameter <version> to install different dupilcity versions

that's of the top of my hat. you'd probably need to provide a patch or a patched duply script for that.

thanks for your commitment.. ede

ok, here's how it works now:

1. as long as you are root, you may specify a path. in case of ordinary user the path is set to ~/.duply/duplicity with additional, non-obligatory parameter <version>.
2. path for locally installed duplicity is held in LOCAL_DUPL_PATH in profile conf file. to make duply select it first i changed the order of '### read configuration' and '# check system environment' sections. looks like the change doesn't affect duply work.
3. done.
4. done (bash $RANDOM variable is used instead of mktemp. i found that mktemp behaves differently on e.g. HP-UX).
5. done.

ant other suggestions?
