revlog: update the split + transaction test
We add section, increase the amount of comments and simplify some of the
constructs. We are about to build more on top this tests so lets do a small
cleanup first.
pub type ExitCode = i32;
/// Successful exit
pub const OK: ExitCode = 0;
/// Generic abort
pub const ABORT: ExitCode = 255;
// Abort when there is a config related error
pub const CONFIG_ERROR_ABORT: ExitCode = 30;
/// Indicates that the operation might work if retried in a different state.
/// Examples: Unresolved merge conflicts, unfinished operations
pub const STATE_ERROR: ExitCode = 20;
// Abort when there is an error while parsing config
pub const CONFIG_PARSE_ERROR_ABORT: ExitCode = 10;
/// Generic something completed but did not succeed
pub const UNSUCCESSFUL: ExitCode = 1;
/// Command or feature not implemented by rhg
pub const UNIMPLEMENTED: ExitCode = 252;
/// The fallback path is not valid
pub const INVALID_FALLBACK: ExitCode = 253;
