-The Git Autoinstaller
-
-TODO NOW:
-
-- Whip the install script into a state where we can actually use it to
- pilot new installs.
- - Command line based scripts are thin-client; controller/display
- logic and the model live on scripts servers, and a small
- client that listens to a forwarded port for commands that need
- to be run with the user's tickets
- - Graphical applications can't be done via X-forwarding, which is
- disabled. debconf provides this functionality and is decently
- available on Debathena machines, although it is a slight stretch
- from its normal use case (also note that there is a "debconf" Python
- module). gdialog can use zenity to produce dialogs. You can
- also ship locker software.
- - 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.
-
-- Keep my sanity when upgrading 1000 installs
- - Replace gaierror with a more descriptive name (this is a DNS error)
-
-- Make the rest of the world use Wizard
- - Make parallel-find.pl use `sudo -u username git describe --tags`
- to determine version. Make parallel-find.pl have this have greater
- precedence. This also means, however, that we get
- full mediawiki-1.2.3-2-abcdef names (Have patch, pending testing and commit)
- - Make deployed installer use 'wizard install' /or/ do a migration
- after doing a normal install (the latter makes it easier
- for mass-rollbacks).
-
-- Pre-emptively check if daemon/scripts-security-upd
- is not on scripts-security-upd list (/mit/moira/bin/blanche)
-
-- Redo Wordpress conversion, with an eye for automating everything
- possible (such as downloading the tarball and unpacking)
+- [SCRIPTS] MediaWiki 1.9.3 and 1.6.7
+
+- Plugin-ify! Hook-ify! In more detail, applications should all be moved
+ out into plugins, scripts specific behavior should be moved into
+ plugins, and hooks need to be made available so that we can exert
+ the correct level of control.
+
+- [SCRIPTS] Wordpress needs to get rid of the siteurl hack, so that it
+ actually has a fully-qualified URL http://foo.scripts.mit.edu/blah.
+ This will also fix Wordpress's cron functionality. We should be
+ careful not to write over users who are on vhosts. We should figure
+ out who is still on twiddle paths. We should make sure the redirect
+ is handled correctly.
+
+- Remerges aren't reflected in the parent files, so `git diff` output is
+ spurious. Not sure how to fix this w/o tree hackery.
+- Sometimes users remove files. Well, if those files change, they automatically
+ get marked as conflicted. Maybe we should say for certain files "if they're
+ gone, they're gone forever"? What is the proper resolution?
+
+- Parse output HTML for class="error" and give those errors back to the user (done),
+ then boot them back into configure so they can enter in something different
+
+- [SCRIPTS] If you try to do an install on scripts w/o sql, it will sign
+ you up but fail to write the sql.cnf file. This sucks.
+
+- [SCRIPTS] Web application for installing autoinstalls has a hard
+ problem with credentials (as well as installations that are not
+ conducted on an Athena machine.) We have some crazy ideas involving a
+ signed Java applet that uses jsch to SSH into athena.dialup and
+ perform operations.
- Pay back code debt
- - Genericize callAsUser and drop_priviledges in shell
+ - Tidy up common code in callAsUser and drop_priviledges in shell;
+ namely cooking up the sudo and environment variable lines
- Summary script should be more machine friendly, and should not
output summary charts when I increase specificity
- - Summary script should do something intelligent when distinguishing
- between old-style and new-style installs
- - Report code in wizard/command/__init__.py is ugly as sin. Also,
- the Report object should operate at a higher level of abstraction
- so we don't have to manually increment fails. (in fact, that should
- probably be called something different). The by-percent errors should
- 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? (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
- resilient
- - PHP end of file allows omitted semicolon, can result in parse error
- if merge resolutions aren't careful.
- Other stuff
- - Make single user mass-migrate work when not logged in as root
+ - Add support for mypristine workflow
+ - Figure out why Sphinx sometimes fails to crossref :func: but wil
+ crossref :meth:, even though the dest is very clearly a function.
+ Example: :func:`wizard.app.php.re_var`
+ - The TODO extension for Sphinx doesn't properly force a full-rebuild
+ - Make single user mass-migrate work when not logged in as root. The
+ primary difficulty is making the parallel-find information easily
+ accessible to individual users: perhaps we can do a single-user
+ parallel-find on the fly.
- 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
- It should be able to handle installs like Django where there's a component
that gets installed in web_scripts and another directory that gets installed
in Scripts.
- - ACLs is a starting point for sending mail to users, but it has
- several failure modes:
- - Old maintainers who don't care who are still on the ACL
- - Private AFS groups that aren't mailing lists and that we
- can't get to
- A question is whether or not sending mail actually helps us:

COMMIT MESSAGE FIELDS:
Committer: Real Name <username@mit.edu>
Author: lockername locker <lockername@scripts.mit.edu>
-NOTES:
-
-- 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.
-
-- Currently all repositories are initialized with --shared, which
- means they have basically ~no space footprint. However, it
- also means that /mit/scripts/wizard/srv MUST NOT lose revs after
- deployment.
-
OVERALL PLAN:
+[ XXX: doc/deps.rst ]
* Some parts of the infrastructure will not be touched, although I plan
on documenting them. Specifically, we will be keeping:
- - parallel-find.pl, and the resulting
- /mit/scripts/.htaccess/scripts/sec-tools/store/scriptslist
-
-* The new procedure for generating an update is as follows:
- (check out the mass-migration instructions for something in this spirit,
- although uglier in some ways; A indicates the step /should/ be automated)
-
- 0. ssh into not-backward, temporarily give the daemon.scripts-security-upd
- bits by blanching it on system:scripts-security-upd, and run parallel-find.pl
-
- 1. Have the Git repository and working copy for the project on hand.
-
- 2. Checkout the pristine branch
-
- 3. Run wizard `prepare-pristine APP-VERSION`
-
- 4. Checkout the master branch
-
- 5. [FOR EXISTING REPOSITORIES]
- Merge the pristine branch in. Resolve any conflicts that our
- patches have with new changes. Do NOT let Git auto-commit it
- with --no-commit (otherwise, you want to git commit --amend
- to keep our history clean
-
- [FOR NEW REPOSITORIES]
- Check if any patches are needed to make the application work
- on Scripts (ideally, it shouldn't.) Run
- `wizard prepare-new` to setup common filesets for our repositories.
+ - get-homedirs.sh. which needs to be run as root on scripts. Store
+ in /mit/scripts/sec-tools/store/scriptslist
- If you are running a PHP script, there is usually a php.ini file
- that we package. You can see previous instances of this patch
- at /mit/scripts/deploy/php.ini/ as well as in the repositories
- of any already migrated scripts. We hope to make these changes
- unnecessary once PHP 5.3 arrives.
-
- 6. Check if there are any special update procedures, and update
- the wizard.app.APPNAME module accordingly (or create it, if
- need be).
-
- 7. Run 'wizard prepare-config' on a scripts server while in a checkout
- of this newest version. This will prepare a new version of the
- configuration file based on the application's latest installer.
- Manually merge back in any custom changes we may have made.
- Check if any of the regular expressions need tweaking by inspecting
- the configuration files for user-specific gunk, and modify
- wizard.app.APPNAME accordingly.
-
- 8. Commit your changes, and tag as v1.2.3-scripts (or scripts2, if
- you are amending an install without an upstream changes)
-
- NOTE: These steps should be run on a scripts server
-
- 9. Test the new update procedure using our test scripts. See integration
- tests for more information on how to do this.
-
- http://scripts.mit.edu/wizard/testing.html#acceptance-tests
+ - parallel-find.pl, and the resulting
+ /mit/scripts/sec-tools/store/versions
- GET APPROVAL BEFORE PROCEEDING ANY FURTHER
+[ XXX: doc/deploy.rst ]
+ GET APPROVAL BEFORE PROCEEDING ANY FURTHER;
+ THIS IS PUSHING THE CHANGES TO THE PUBLIC
NOTE: The following commands are to be run on not-backward.mit.edu.
You'll need to add daemon.scripts-security-upd to
12. Run parallel-find.pl to update our inventory
-* For mass importing into the repository, there are a few extra things:
-
- * Many applications had patches associated with them. Be sure to
- apply them, so later merges work better.
-
- # the following operation might require -p1
- patch -p0 < ../app-1.2.3/app-1.2.3.patch # [FIDDLY BIT]
-
- * When running updates, if the patch has changed you will have to
- do a special procedure for your merge:
-
- git checkout pristine
- # NOTE: Now, the tricky part (this is different from a real update)
- git symbolic-ref HEAD refs/heads/master
- # NOTE: Now, we think we're on the master branch, but we have
- # pristine copy checked out
- # NOTE: -p0 might need to be twiddled
- patch -p0 < ../app-1.2.3/app-1.2.3.patch
- git add .
- # reconstitute .scripts directory
- git checkout v1.2.2-scripts -- .scripts
- git add .scripts
- # NOTE: Fake the merge
- git rev-parse pristine > .git/MERGE_HEAD
-
- You could also just try your luck with a manual merge using the patch
- as your guide.
-
+[ XXX: doc/metadata.rst ]
* The repository for a given application will contain the following files:
- The actual application's files, as from the official tarball
- A .scripts directory, with the intent of holding Scripts specific files
if they become necessary.
+ - .scripts/dsn, overriding database source name
+
