+# Meeting 20.03.2024
+
+## gana
+
+we can delete the gana submodul from the donau. We use the gana from the 
exchange anyway.
+
+how to update gana:
+
+1. update gnu-taler-error-codes/registry.rec and 
gnu-taler-error-codes/taler_error_codes.rst (Donau error code (ec) 8600 - 8700.
+
+2. update gana in exchange
+   
+   ```bash
+   cd contrib/gana
+   git pull
+   checkout master
+   git add . # gana-bumb commit and push
+   # install exchange
+   ```
+
+## keys
+
+the keys route has two main tasks: 
+
+1. act as route and return requested keys
+
+2. sign for other routes! -> Other routes do not have access to the private 
keys!
+   
+   
+- We do not sort the keys therefore we don't need a heap. We can directly 
iterate over the donation unit map. 
+- krd_array can be deleted. Its already hashed ???
+- Put KeysResponseData into the main datastructure. It contains the etag (year 
in our case and version)
+
+## issue receipts
+
+We must ensure that the update the receipts to date of a charity and the 
receipt request are both saved in the database or thrown away. To do this, we 
need transactions. Its best practice to try a database insert 3 times to reduce 
the risk of serialization errors (if it has not worked after 3 times, the error 
is probably somewhere else).
+
+## uncrystify
+
+install uncrystify. If so you cant upload bad formated code. With uncrystify 
you can automatically format the code.
