How to easily upgrade sites

Preparing

• Get the site down. this is important otherwise you're fucked with dbase patches
• get a cvs copy of both old version and new version. (or from a tarball).

Updating scripts

• update scrips/ folder. usually cp'ing the new script files should do the trick. or cp the whole folder. if files differ check if they're modified.

Updating website.

• Check which files are changed.

diff -r --brief --exclude=CVS /path/to/old/version/website/dir /path/to/newversion/website/dir

(mat)Example:

diff -r --brief --exclude=CVS /home/maritimes2/website/ /home/maritimes2/sitename/ | more

• copy over the files that are changed. don't forget to copy over new files.

Updating local

(mat)Example:

diff -r --brief --exclude=CVS /home/maritimes/local/ /home/maritimes2/local/ | more

• There are 3 dirs: include/ config/ templates that need to be checked.
• Sfactive.cfg
  • This is a hard one. i usually do diff them and go about line by line.

diff -cbw current_file new_file | more 

• templates
  • compare what got changed between oldversion and newversion with what differs from oldversion with current files:

diff -r --brief --exclude=CVS /path/to/old/version/templates/dir /path/to/newversion/templates/dir
diff -r --brief --exclude=CVS /path/to/old/version/templates/dir /path/to/current/templates

• • copy over new files. for modified files you'll have to diff -cbw them one by one and merge them. if people modified their own templates they'll for sure are able to merge them in admin themselves usually.

• includes
  • see like templates.

(mat)Example: diff -r --brief --exclude=CVS /home/maritimes2/local/ /home/maritimes/local/ | more

Patching the dbase

• see what database patches there are for your release (they're in sf-active/install/)
• apply them one by one in the order they should be applied (usually this doesn't matter).

Permissions

• if you copy over existing files, permissions should stay.
• for new files, usually we do this:
  • files: 664 | directories: 775
  • owner: yoursite:yoursite
  • webwritable files : www:yoursite so apache can write to them and groups can write to them in shell
• to update large dirs (like uploads/), use find (you might get errors with chmod -R)

find . -type f -exec chmod 664 {} \;

Bring site up

• Change the eventual include path in httpd.conf
• make sure sfactive.cfg points to new shared/dir
• make sure your site is included in the correct global.cfg file

Post upgrade

• You might have to regenerate articles. do 300 most recent ones first, then start from zero
• if you go to 0.9.4: add a default language in the admin (otherwise publish and alikes are broken)
• Go to the fridge/cellar and serve yourself quality belgian beer
