Based on various conversations in the past I have been working on a semi-interesting features: using mnemonic encoding to turn ticket hashes into something that humans can remember.
This uses a built-in dictionary to convert a hex hash (e.g. '74a95e62')
into a series of words ('TOAST MOZART TULIP'). There are actually
several standard algorithms; the one I like best is mnemonic encoding,
and there's a sample implementation here:
https://github.com/singpolyma/mnemonicode
A four-byte hash can be stored as three words, which is just the right
size to fit in the human brain. However, the algorithm copes fine with
longer or shorter hashes (you get more or fewer words).
I've done a basic implementation of this, which is now in the
dg-codenames branch; the algorithm itself and its dictionary is in
src/mnemonic.c.
You can now do:
./fossil ticket history 'TOAST MOZART TULIP'
...to see an individual ticket.
If you want to list the memorable names in a ticket report, add this
line to the report's query statement:
mnemonic_encode(substr(tkt_uuid,1,8)) AS 'Id',
To play with the algorithm, do:
echo "select mnemonic_encode('12345678');" | ./fossil sqlite3
or echo "select mnemonic_decode('CRASH CHAPTER CASINO');" | ./fossil
sqlite3
...to encode and decode.
Right now the only thing I've changed to accept mnemonic encodings as
well as hashes is the "fossil ticket" command; I haven't touched the web
UI as it's rather complicated. So right now the only way to get the
mnemonic for a bug is to change the ticket report as described above or
to manually get the encoding. Here are a few from the Fossil ticket
database to get you started. This lets you see what sort of codename is
produced:
74a95e62cf TOAST MOZART TULIP

"wiki unlist" as a possible solution to deleting wiki pages.
I'd appreciate any comments --- including any suggestions as to whether
this is actually a useful feature. I, personally, find these things
vastly easier to handle than 8-character hex strings. However I hear
rumours that other peoples' opinions are valid too...
