Bug #9882: Regex problem
Chris G. encountered a regex problem when using a ‘-‘ character at the front of a character class. Although such a character is allowed at the front of the class according to the ECMA standard, the gcc 4.9.2 implementation of std::regex resulted in giving a “not found”, but yielded a successful result when ‘-‘ was placed at the end. The bug appears to have been fixed in gcc 4.9.3. The problem was encountered because of migrating to the @std@ regex library from cpp0x, which, under the covers, has used the boost implementation.
Discussion about MicroBooNE POT information storage
MicroBooNE has a use case where they need to insert POT information at a finer granularity than what their DAQ system currently calls an event. The suggestion is to create a source that emits a new event per POT value update, possibly with dummy products, as necessary.
