• N-gram (Debian -> De eb bi ia an): Pros: be able to match the part of any words, no search missing. cons: too many match, expensive calculation cost.
• suffix array (debian -> an, bian, debian, ebian, ian, n): arary of ponters (sorted), pros: no search missing, cons: huge index (4 times on 32bit arch), need to remain the original source, expensive on indexing (sorting)
• asian language issue: word segmentation (word suffix), character encoding
• how to segment: longest match from dics: kakasi (for japanese), morphological analysis: noun, verb... chasen, mecab (for many languages, but only for japanese)
• word suffix: $BF0$/(B $B"*(B $BF0$+$J$$(B | $BF0$-$^$9(B (variants)
• /usr/share/doc: there're no i18n policy, info: no info policy
• future: desktop search system, web cache search, GNOME: Beagle (based on dotlucene), KDE: not yet. (will be implemented on KDE4)
• web cache search: there're some implementations (WWWOFFLINE, squid), not there for local cache (mozilla, firefox), need to integrate with desktop search

• tools: testing migration: britney + hints, release critical bugs
• security stats: merkel.d.o/~joeyh/testing-security.html
• britney runs shortly after dinstall - results are only visible in dists/ after next dinstall, testing output and excuses are published directly, britney can be re-run during the day
• what could have worked better: release team shouldn't be crushed under unfreeze requests in the final stage / shorter base-freeze / fewer packages in base-freeze / freezing also development-packages earlier? / version-tracking on bugs.d.o / prevent cd download madness on monday / better way for final qa of release and cds / build cds from final official archive state / use code-names when you mean the release / even more hints / security after release
• further improvements in etch: time based release. dec 2006. / only few blockes: toolchain, x.org, doc-in-main, firmware-in-main, ports.d.o, amd64, secure apt / other issues are only pet release goals / lesser dependency between shlib bumps, transitions. / more qa: automatic package install tests. / less pain with specific archs / better interaction kernel and installer / better udeb-handling in britney / checklist with dependencies: no out-of-order processing / pseudo-package for release notes / more uptodate information on release.d.o

debbugs $B$d(B BTS $B$J$I$K$D$$$F!#(B

• web interface requirements: always available, easy to access
• email interface requirements: easy to use from anywhere, quickly reflected on website, info on what was changed for manual recovery
• breaks up bugs into manageable sections, not really applicable outsize of debian, selection byte source package/maintainer/submitter/severity/and tag also possible, finding the interesting bugs is hard
• database structure: filesystem based db, split into archived and active bugs, hashed by last two digits of bug number, text files!, ..four per bug, ..hence the hashing
• index.db and index.archive: simple summary of all bugs, needed when searching for interesting bugs (or else you have to poen 50,000 summary files)
• bugscan: the script that generates the rc bug list, used to generate the old bugs lists and the non-wishlist bugs graphs, single idea: troll through the status/summary files and collate the interesting info into a graph or web page, fairly easy to hack on and completely non-instructive
• developed for debconf 2003(oslo) for bugsquashing, changes to pkreport.cgi to support passing through a list of intersting bug numbers, a claims.cgi script that allowed developers to edit a list of interesting bugs andmake the querying less ugly, (not intergrated and no longer very useful with debbugs not on a developer accessible machine)
• missing features: integration with upstream and downstream BTSes -spam prevention -file grained selection and control of bugs -secrecy and authentication -prettiness

• new Enhances and Breaks relationsships, New postinst arguments for Enhances
• new ways of expressing dependices, new source package format
• FILTERS: modify data about the files in a package, happens when package is unpacked or removed, don't get told which (so they don't give different answers)
• Diversions / Stat Overrides / FHS Transitions / Multi-Arch (filter /usr/lib to /usr/lib/i486-linux-gnu automatically), rpm --relocate
• CLASSES: every file is placed in a class, or the default, class provides install and remove methods, methods are run with filtered information
• Config Files / DOcumentation / Optional content (/usr/share in multi-arch?) / Remove-only files (logs, potential configuration)
• dpkg v2: almost certainly something faster than dpkg/rfc822 / undo effects of dpkg-divert and stat-override / register conditional config files and log files in postinst / signature of file data can be signed
• BAD IDEAS: single-file source package, "spec" file to replace debian/, file-based dependencies, postinst.d/other script hooks
• roadmap: 1.13 i unstable for 6 months, freeze, new stuff into experimental, repeat until base freee, 1.16 for etch, 2.0 developed along side, expected for etch +1 or later
