Seastar's on_internal_error() is a useful replacement for assert() but it's inconvenient that it requires each caller to supply a logger - which is often inconvenient, especially when the caller is a header file. So in this patch we introduce a utils::on_internal_error() function which is the same as seastar::on_internal_error() (the former calls the latter), except it uses a single logger instead of asking the caller to pass a logger.

// Seastar's on_internal_error() is a replacement for assert(). Instead of
|
|
// crashing like assert(), on_internal_error() logs a message with a
|
|
// backtrace and throws an exception (and optionally also crashes - this can
|
|
// be useful for testing). However, Seastar's function is inconvenient because
|
|
// it requires specifying a logger. This makes it hard to call it from source
|
|
// files which don't already have a logger, or in code in a header file.
|
|
//
|
|
// So here we provide Scylla's version of on_internal_error() which uses a
|
|
// single logger for all internal errors - with no need to specify a logger
|
|
// object to each call.
