TODO NOW:
- Keep my sanity when upgrading 1000 installs
- - Custom merge algo: absolute php.ini symlinks to relative symlinks (this
- does not seem to have been a problem in practice)
- - Custom merge algo: check if it's got extra \r's in the file,
- and dos2unix it if it does, before performing the merge
- - Prune -7 call errors and automatically reprocess them (with a
- strike out counter of 3)--this requires better error parsing.
- - IOError should be aggregated, right now contains custom string
- that makes this not possible. Partition on a colon.
- Replace gaierror with a more descriptive name (this is a DNS error)
- - Stronger skips means that backup failures should also be avoided
- - Distinguish between types of backup failures
- - Ignore empty blacklists; they should all have reasons
- - wizard upgrade should have different exit codes for merge failure
- and blacklist error. This means augmenting error classes to have
- exit codes in them
-
-- Distinguish from logging and reporting (so we can easily send mail
- to users)
- - Figure out a way of collecting blacklist data from .scripts/blacklisted
- and aggregate it together
-
-- Let users use Wizard when ssh'ed into Scripts
- - Make single user mass-migrate work when not logged in as root
- Make the rest of the world use Wizard
- Make parallel-find.pl use `sudo -u username git describe --tags`
- Redo Wordpress conversion, with an eye for automating everything
possible (such as downloading the tarball and unpacking)
+- Web application for installing autoinstalls has a hard problem
+ with credentials (as well as installations that are not conducted
+ on an Athena machine.) Possible solutions include asking the user
+ to SSH into an athena machine and run a bunch of commands, or writing
+ a Java applet (possibly in Clojure or Scala) which gets filesystem
+ permissions and then performs the operations.
+
- Pay back code debt
- Genericize callAsUser and drop_priviledges in shell
- Summary script should be more machine friendly, and should not
also be automated.
- Indents in upgrade.py are getting pretty ridiculous; more breaking
into functions is probably a good idea
- - Move resolutions in mediawiki.py to a text file
+ - Move resolutions in mediawiki.py to a text file? (the parsing overhead
+ may not be worth it)
- Investigate QuotaParseErrors
- If a process is C-ced, it can result in a upgrade that has
an updated filesystem but not updated database. Make this more
if merge resolutions aren't careful.
- Other stuff
+ - Make single user mass-migrate work when not logged in as root
- Don't use the scripts heuristics unless we're on scripts with the
AFS patch. Check with `fs sysname`
- Make 'wizard summary' generate nice pretty graphs of installs by date

-PHILOSOPHY ABOUT LOGGING
-
-Logging is most useful when performing a mass run. This
-includes things such as mass-migration as well as when running
-summary reports. An interesting property about mass-migration
-or mass-upgrade, however, is that if they fail, they are
-idempotent, so an individual case can be debugged simply running
-the single-install equivalent with --debug on. (This, indeed,
-may be easier to do than sifting through a logfile).
-
-It is a different story when you are running a summary report:
-you are primarily bound by your AFS cache and how quickly you can
-iterate through all of the autoinstalls. Checking if a file
-exists on a cold AFS cache may
-take several minutes to perform; on a hot cache the same report
-may take a mere 3 seconds. When you get to more computationally
-expensive calculations, however, even having a hot AFS cache
-is not enough to cut down your runtime.
-
-There are certain calculations that someone may want to be
-able to perform on manipulated data. As such, this data should
-be cached on disk, if the process for extracting this data takes
-a long time. Also, for usability sake, Wizard should generate
-the common case reports.
-
-Ensuring that machine parseable reports are made, and then making
-the machinery to reframe this data, increases complexity. Therefore,
-the recommendation is to assume that if you need to run iteratively,
-you'll have a hot AFS cache at your fingerprints, and if that's not
-fast enough, then cache the data.

NOTES:
-- It is not expected or required for update scripts to exist for all
+- It is not required nor expected for update scripts to exist for all
intervening versions that were present pre-migration; only for it
to work on the most recent migration.
also means that /mit/scripts/wizard/srv MUST NOT lose revs after

-- Full fledged logging options. Namely:
- x all loggers (delay implementing this until we actually have debug stmts)
- - default is WARNING
- - debug => loglevel = DEBUG
- x stdout logger
- - default is WARNING (see below for exception)
- - verbose => loglevel = INFO
- x file logger (creates a dir and lots of little logfiles)

have over a certain threshold of changes.

if they become necessary.
- * .scripts/lock (generated) which locks an autoinstall during upgrade
