 02 May 2023, Niklaus Berger, Forum, Problem with running midas odbxx frontends on a remote machine using the -h option
|
And now we also fixed the client segfault, odb.cxx L8992 also needs to know about the header:
if (rpc_is_remote())
return rpc_call(RPC_DB_COPY_XML, hDB, hKey, buffer, buffer_size, header);

10 Jun 2025, Nik Berger, Bug Report, History variables with leading spaces
|
By accident we had history variables with leading spaces. The history schema check then decides that this is a new variable (the leading space is not read
from the history file) and starts a new file. We found this because the run start became slow due to the many, many history files created. It would be
nice to just get an error if one has a malformed variable name like this.
