I have been looking at this a bit more. It seems like part of the
complexity came from two commits that moved common calls from cmdline
tools to the popt_common_credentials callback:
d6d889 s3:popt_common: simplify popt_common_credentials handling
4fb0e6 s3:popt_common: let POPT_COMMON_CREDENTIALS imply logfile and conffile loading
Sharing the common code is good, but i am wondering if the post hook in
popt is the best place for that. Right now i am exploring whether a
cleaner approach would be:
- Move the complex calls from the post hook to a helper function that
can be called from the cmdline tools (there is already
source3/lib/util_cmdline.c which might be a good place).
- Introduce a new cmdline_contexts.c, similar to server_contexts, but
with the additional checks for cmdline tools.
- That would require introducing a "set" function for the messaging
context used in db_open.
