TODO NOW:
-- Consider adding user config to repository
-- Put php.ini links in repos (probably will need another
- script in .scripts)
-- Version configuration
+- We have safe, non-braindead
+ version detection with `git describe --tags`. Switch
+ everything to use it. (I think the only thing left is
+ parallel-find.pl)
+- wizard.util is pretty braindead at this point. Fix up
+ the wildly varying conventions in it.
+- Move migration code into Wizard, since we already deal
+ with installation there anyway.
-- Consider making usermode wizard operation a support mode
- (mostly for letting users upgrade things themself)
+- Better error message if daemon/scripts-security-upd
+ is not on scripts-security-upd list
-- Add repository flag to migrate so that we can specify an
- arbitrary repository to migrate to
+- Fix retarded logging mechanism
- The great initial deploy:
- Turn on mediawiki new autoinstaller
- - Migrate all mediawik installs
-
-- Implement proper deploy log parsing; this basically means we
- need to be able to introspect Git Log. Consider using git-python
- for this. There's also missing functionality, bad error handling
- and hacks in the prototype implementation of upgrade
-
-- Wordpress needs to have .scripts dir in all -scripts versions
- (remember --no-walk!) (also make .scripts/.htaccess)
-- Wordpress needs to have a .scripts/update script written for
- its latest version (do this after its migration)
-- Wordpress needs to check for php.ini files (which it almost
- certianly has) and commit messages
+ - Migrate all mediawiki installs
+
+Doing Wordpress:
+- Build automation for generating config files; this automation
+ will be shared with the migrate script and the installer script
+ (migrate script needs to be able to pull out values from config
+ file, so will we; installer script needs to be able to run
+ the installer to generate config files, so will this)
+- This should all be automated:
+ - Wordpress needs to have .scripts dir in all -scripts versions
+ (also make .scripts/.htaccess)
+ - Wordpress needs to have a .scripts/update script written for
+ its latest version (do this after its migration)
+ - Wordpress needs to check for php.ini files (which it almost
+ certianly has) and commit messages
+ - Wordpress needs user config and php.ini links made
- Summary script should be more machine friendly, and should not
output summary charts when I increase specificity
+- Summary script needs to be updated for new format
+
+Some other stuff to do in your copious free time:
- Check how many autoinstalls are missing w bits for
daemon.scripts (this would need pyafs)
-- Consider fixing Wizard's commit messages
+- Make scripts AFS patch advertise its existence so we can check for it.
+ (This might be otherwise possible using `fs sysname`
+- Implement proper deploy log parsing; this basically means we
+ need to be able to introspect Git Log. Consider using git-python
+ for this.
+- Make 'wizard summary' generate nice pretty graphs of installs by date
+ (more histograms, will need to check actual .scripts-version files.)
PULLING OUT CONFIGURATION FILES IN AN AUTOMATED MANNER
NOTES:
-- A perfectly formed autoinstall with upgrade paths for all of
- the intervening versions is not really feasible to implement.
- As such, we want to migrate everything to -scripts, and then
- generate a -scripts2 with the correct .scripts directory.
- We will then nop update some installs, but this will prevent
- us from having to migrate and update concurrently. Treat
- a scripts2 upgrade from migration the same way you would treat
- a botched scripts upgrade.
+- It is not expected or required 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
on documenting them. Specifically, we will be keeping:
- parallel-find.pl, and the resulting
- /mitalso make .scripts/.htaccess/scripts/sec-tools/store/scriptslist
- This script might need to be adapted if we decide to nuke
- .scripts-version files.
-
- - The current install scripts will be kept in place, sans changes
- necessary to make them use Git install of copying the script over.
- Porting these scripts to Python and making them modular would be
- nice, but is priority. For the long term, seeing this scripts
- be packaged with rest of our code would be optimal.
