v75 v76 3 3 This page contains specific suggestions for projects we would like to see in the Summer of Code. Note that they vary a lot in required skills and difficulty. We hope to get applications with a broad spectrum. 4 4 5 If you are interested in working on any of these projects, please contact the developers referenced next to each item.5 If you are interested in working on any of these projects, please contact the Mentors listed at the bottom of the page. 6 6 7 7 In addition, you may wish to discuss your proposal on IRC -- join us on #tahoe-lafs on irc.freenode.net. … … 11 11 Deadlines and directions for students' applications to the Google Summer-of-Code can be found on [http://code.google.com/soc/ the Google pages]. 12 12 13 ||''Project''||''Difficulty''||''Contact''|| 14 ||[#RedundantArrayofIndependentClouds Redundant Array of Independent Clouds]||Medium||[mailto:zooko@zooko.com Zooko Wilcox-O'Hearn]|| 13 ||''Project''||''Difficulty''|| 14 ||[#RedundantArrayofIndependentClouds Redundant Array of Independent Clouds]||Medium|| 15 ||[#ShareMigration Share Migration]||Medium|| 16 17 18 ---- 19 15 20 16 21 = Redundant Array of Independent Clouds = … … 19 24 20 25 * Estimated difficulty: Medium 21 * Contact:22 26 23 27 See [http://allmydata.org/~zooko/RAIC.png the RAIC diagram]. Add backends to the storage servers so that they store their shares on a cloud storage system instead of on their local filesystem. See #999 for details, including pointers to the relevant source code. 28 29 = Share Migration = 30 31 Project summary: 32 33 * Estimated difficulty: Medium 34 35 When uploading a file to a grid, Tahoe-LAFS will make sure that the file is 36 healthy (a good discussion of what healthy means is found in #778) before 37 reporting that the file is uploaded successfully. Tools to effectively 38 maintain file health (or to adapt to new definitions of health) aren't 39 quite complete, however -- our users have had several use cases that aren't 40 easily addressed with what we have. Students taking this project would be 41 building tools to address those use cases. 42 43 A good starting point would be to become familiar with how files are placed on 44 a grid. [http://allmydata.org/trac/tahoe-lafs/browser/docs/architecture.txt architecture.txt], 45 [http://allmydata.org/trac/tahoe-lafs/browser/docs/specifications/file-encoding.txt file-encoding.txt], 46 [http://allmydata.org/trac/tahoe-lafs/browser/docs/specifications/mutable.txt mutable.txt], 47 [http://allmydata.org/trac/tahoe-lafs/browser/src/allmydata/immutable/upload.py the immutable file upload code], and 48 [http://allmydata.org/trac/tahoe-lafs/browser/src/allmydata/mutable/publish.py the mutable file upload code] are good 49 places to do that. Also, you might want to look at the 50 [http://allmydata.org/trac/tahoe-lafs/browser/src/allmydata/storage/server.py storage server code] to understand that 51 better. Some good tickets to start looking at are #699, #543, and #232; you'll 52 find that those link to other tickets. 53 54 There are many ways to help address these issues. Some ideas: 55 56 * Alter the CLI and the WUI to give users the ability to rebalance 57 files that they've uploaded already. (#699) 58 * Build tools that allow node administrators to moves shares around 59 a grid (#543, #864) 60 * Alter Tahoe-LAFS to rebalance mutable files when uploading a new version 61 of them. (#232) 62 63 Any one of these projects is probably too small to fill a summer, but combined they would be a big usability improvement for Tahoe-LAFS. 64 65 Depending on how you address this, this is tightly integrated with ideas of 66 file health and accounting, so prospective students would do well to explore 67 those open issues, too. A good accounting jumping-off point is #666. A good 68 jumping-off point for health is #778. 24 69 25 70 ---- … … 27 72 ''Who is willing to spend about five hours a week (estimated) helping a student do it right?'' 28 73 [[br]] 29 * [http://testgrid.allmydata.org:3567/uri/URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa/wiki.html Zooko Wilcox-O'Hearn] (Python/C/C++/JavaScript, cryptography) 74 * [http://testgrid.allmydata.org:3567/uri/URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa/wiki.html Zooko Wilcox-O'Hearn] (Python/C/C++/JavaScript, cryptography) ||[mailto:zooko@zooko.com <zooko@zooko.com>] 30 75 * [http://www.randombit.net Jack Lloyd] (C/C++/Python, cryptography) 31 76 * David-Sarah Hopwood (david-sarah at jacaranda.org) (Python/C/JavaScript, SFTP frontend, security+cryptography)
