Right, I was not ever aware of such limitation until I just now looked at the .odb and .xml writing code. Definitely string length

 26 Apr 2017, Konstantin Olchanski, Info, added db_get_value_string()
|
Since we have been regularly running into problems with db_get_xxx(TID_STRING) and string buffers of mismatched size,
I now implemented db_get_value_string(hdb, hkey, key_name, index, &string, create).

I changed the mhttpd odb inline editor to use the json-rpc interface. Good things:
- browser no longer complains about obsolete synchronous ajax calls

16 May 2017, Konstantin Olchanski, Bug Report, problem with odb strings and db_get_record()
|
Suddenly the mhttpd odb inline editor is truncating the odb string entries to the actual length of the
stored string value, this causes db_get_record() explode with "structure mismatch" errors. (Not my
fault, You Honor! Honest!). For example, I see these errors from al_check() after changing

31 May 2017, Konstantin Olchanski, Info, modified db_watch() arguments

for reasons unknown, db_watch() did not have an "info" parameter passed through to the callback
handler function, like it is done with db_open_record().

The mess with db_get_record() and db_open_record() is even deeper than I thought. There are several anomalies.

Done to all in-tree programs, except for mana.c (not using it), sequencer.cxx (cannot test it) and a few places where watching a TID_INT.
