TODO NOW:
-- Make wizard install accept appname-head (so that you can do a test with
- head, and do things without tags). Also make it accept commit hashes.
- In fact, let it accept any committish. Figure out what to do if we
- do a test script with x.y.z when we REALLY mean x.y.z-scripts. XXX!!!
-- Do early validation of inputs for configuration
-- Let 'wizard configure' be interactive
-- Parse output HTML for class="error" and give those errors back to the user,
- then boot them back into configure
+- 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.
+
+- wizard install wordpress should ask for password. One problem with this is that
+ Wordpress will still send mail with the wrong username and password, so Wordpress
+ will need to be patched to not do that. Alternatively we can initally set the admin
+ email to a null address and then fix it manually.
+- --raw parameter for install which means an arbitrary commit can be installed
+- 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
- Get rid of our custom sizing code and use dialog's built-in sizing (i.e. width=0, height=0).
Maybe our sizing code is superior, maybe not.
- 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)
-
- 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.
+ 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
- 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
if merge resolutions aren't careful. `php -l` can be a quick stopgap
- Other stuff
- - Make single user mass-migrate work when not logged in as root
+ - 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
+ - Code annotation!
+ - 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

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`
-
- X. Commit, with name "Appname x.y.z"
-
- 4. Checkout the master branch
-
- 5. 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
-
- X. Commit, with name "Appname x.y.z-scripts". This is going to be
- amended.
-
- 6. 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. Commit with --amend, and
- propagate back to your local copy (git reset --hard HEAD~; git pull afs).

- 7. Check if there are any special update procedures, and update
- the wizard.app.APPNAME module accordingly. If this is the first
- time you are performing an upgrade, implement upgrade() in your
- Application class. (XXX: extended instructions here). Test
- the new update procedure using our test scripts (preferably
- on a scripts server). Check this page for more info on our
- integration tests:

- tag as v1.2.3-scripts (or scripts2, if you are amending an install
- without an upstream changes)

9. Push all of your changes in a public place, and encourage others
to test, using --srv-path and a full path.

* 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
+ * When mass producing updates, if the patch has changed you will have to
do a special procedure for your merge:
git checkout pristine
You could also just try your luck with a manual merge using the patch
as your guide.
+[ XXX: doc/layout.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.
-* Making the module files for a new application
-
- 1. Create a wizard/app/APPNAME.py file. Create an object Application
- inheriting from wizard.app.Application (check existing modules for
- the boilerplate code).
-
- 2. Implement download(). "wizard prepare-pristine" will use this in order
- to download the next version of an application.
-
- 3. Create a git repository with `git init`
-
- 4. Use `wizard prepare-pristine APP-VERSION` to download the tarball and
- extract it into the directory. If download() doesn't work and you don't
- want to special case it (for example, you need a /really old version/
- for record-keeping purposes), replace APP-VERSION with PATH, where PATH
- is the tarball to extract.
-
- 5. `git commit -asm "APP VERSION"`
-
- 6. Check if any patches are needed to make the application work
- on Scripts (ideally, it shouldn't.) Pre-existing patches
- live in /mit/scripts/deploy/APP-VERSION/ directories.
-
- 7. Run `wizard prepare-new` to setup common filesets for our repositories.
-
- 8. 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.
-
- 9. Do an initial commit (we're gonna be amending the hell of this)
- using `git commit -asm "APP VERSION-scripts"
-
- 10. Implement install(). Test using `wizard install APP`; you won't
- be able to do a version-specific install with `wizard install APP-VERSION`
- until you generate a tag (which will become out of date once you
- amend the commit.) Now might be a good time to create a
- tests/test-install-APP.sh file (use the other tests as reference) so
- you don't have to constantly enter the parameters when you're doing
- an install.
-
- 11. Push your changes to a directory accessible in the production environment.
- In the case of scripts, this is equivalent to your AFS homedir, and
- the production environment is a scripts.mit.edu. We're going to
- perform a configuration in the production environment to extract
- out the canonical configuration files.
-
- 12. On the production server, call your wizard to perform an installation;
- be sure to use the option --no-commit in order to make propagating changes
- back easier. Inspect the generated configuration files (you can use `git
- status` to find unversioned files that the installer created), and
- implement:
- - extractors
- - substitutions
- These are dictionaries of functions that perform extraction
- and substitution of variables from config files. You don't
- actually have to hand code them; you can app.make_extractors
- and app.make_substitutions on a common dictionary. Check
- out wizard/app/__init__.py for more information on this
- format, as well as other files for samples.
- (XXX: extended instructions here)
- - parametrized_files
- These are any files that contain WIZARD_* variables
- - checkConfig()
- This is a simple, fs based check on whether or not the application
- was configured. Usually checking if some generated config file
- is present is sufficient
- - detectVersion()
- You might be able to reuse machinery from extractors (namely, whatever
- function you were using to generate regular expressions), or you might
- need to code a custom regular expression to parse this out.
- - deprecated_keys?
- Usually you won't need this; use it if there's a configuration variable
- that needs to get parametrized, but isn't actually necessary and
- gets obsoleted in a later version. You probably won't know if that's
- the case until later.
-
- 13. With these implemented, `wizard prepare-config` should now work if you run
- it on the installed copy. The configuration file should now contain only
- generic WIZARD_* variables, and no user-specific config. If it is, your
- script was buggy; try again.
-
- 14. The current changes in the working copy should be merged in. Add any new
- files, and then `git commit --amend`. `git push --force` to stick these
- changes back in the "public" repository.
-
- 15. In your local copy, you can pull the changes by doing `git reset --hard HEAD~`
- and then a `git pull` from the relevant source. Otherwise, Git will complain
- about a non-fast-forward.
-
- 16. Congratulations! You've implemented the installation code for a new install.
- Now goto "ENTER HERE FROM CREATING A NEW REPO" and finish the rest of the
- instructions.
