Problem

• Backups are hudge

Solution

• Remove .rustup (396Mo) .cargo (198Mo) folder after building matrix-synapse (159Mo)

PR Status

• Code finished and ready to be reviewed/tested
• The fix/enhancement were manually tested (if applicable)

Upgrade went well :)

Well, I think it's really not a good idea as with this we always download all rust package at each upgrade...

Well, I think it's really not a good idea as with this we always download all rust package at each upgrade...

I agree with that point, it was one of my thinking when i've done that PR

The point is:

• current x86_64: synapse installation : /opt/yunohost/matrix-synapse (759Mo) including .rustup (379Mo) .cargo (223Mo) so cached files represent 660Mo => 80% of the total installation.

What is it better:

• Not having to download 660Mo of files during upgrades: few seconds won
• In the 660Mo, I don't know which part of the stable toolchain is redownload during upgrade,...
  or
• Having quicker and smaller backup during upgrades
• Having quicker and smaller backup for users doing weekly or daily backup

That's why I though that few seconds added during upgrade worth the space and time saved during backup

* Not having to download 660Mo of files during upgrades: few seconds won

It depends : or some home-hosted servers, this might take a while (1MB/s on a regular ADSL takes a whole minute, fully loading the connection).
But that's not too bad anyway. And you do that only for upgrades.

Well, on slow internet connections but quite powerful servers, I'm not even sure this is time lost (saving 660Mo to copy then compress…). It's energy and heat saved too (much less CPU load).

Maybe a better solution is to store the rust data somewhere else (by example in /opt/yunohost/rust-build-synapse) and make just a symbolic link to this directory for the rust data.
