Once this works and is merged, make a new release. + +This was not entirely achieved: a release was not made. The release +will be carried over to the new iteration. + +# Discussion + +## Development themes + +Lars has thinking further on how to structure Obnam development and is +now thinking that it needs to rotate between three themes: +convenience, performance, and security. Each iteration, or short +sequence of iterations, should pick one of the themes, and +concentrate on that. All three are important for Obnam, so all three +should get attention, but splitting the attention tends to result in a +more chaotic development process. + +## Licensing + +In [[!issue 122]], Alexander asks why Obnam is under the GPLv3 +license, instead of AGPLv3. Lars is inclined to change the license, +but doing so needs a check that no other contributors need to be +asked. + +# Goals + +## Goal for 1.0 (not changed this iteration) + +The goal for version 1.0 is for Obnam to be an utterly boring backup +solution for Linux command line users. It should just work, be +performant, secure, and well-documented. + +It is not a goal for version 1.0 to have been ported to other +operating systems, but if there are volunteers to do that, and to +commit to supporting their port, ports will be welcome. + +Other user interfaces is likely to happen only after 1.0. + +The server component will support multiple clients in a way that +doesn’t let them see each other’s data. It is not a goal for clients +to be able to share data, even if the clients trust each other. + +## Goal for the next few iterations (not changed for this iteration) + +The goal for next few iterations is to have Obnam be performant. This +will include, at least, making the client use more concurrency so that +it can use more CPU cores to compute checksums for de-duplication. + +## Goal for this iteration (new for this iteration) + +The goal of this iteration is to set up a way to check what the +performance of Obnam is, by implementing a simple benchmark, running +that, and recording the results. + + +# Commitments for this iteration + +Lars intends to set up an initial benchmark, and do some chores to +tidy up things. + +* [[!issue 56]] -- SQLite databases for generations have no metadata + about themselves (1h) + - this is relevant for performance so that we can more safely make + changes for performance later +* [[!issue 96]] -- Lacks benchmark of the initial backup a large file + (4h) + - this is the big task for this iteration, the start of doing + systematic benchmarks +* [[!issue 122]] -- Why isn't Obnam licensed under AGPL?
