htdbm enhancement: options for colon-in-username, no-overwrite, extract-entry
I implemented three enhancements for htdbm that I needed:
* htdbm unconditionally disallows colons in user names. This is OK as far as
you want to use DBM files for AuthType Basic. But with AuthType Digest, a colon
is needed to separate user name and realm.
* Though the underlying DBM routines allow to do so, htdbm does not offer a way
to add an entry only if the entry does not exist. This causes race conditions
if multiple applications want to add only new entries using htdbm.
* htdbm does not offer a way to extract a value.
The appending patch solves all three problems for me, by adding options:
-a allows colons in the username.
-k keeps existing entries when you try to add an entry.
-w can be used together with -v to write the database entry to stdout. (The
entry is always written even if verification fails, thus you can say "htdbm
-vwb dbmfile user dummy" to get the DBM entry and disregard the exit code.)
