Nix, the purely functional package manager
3ec02deb20
I noticed that occasional Ctrl-C leaves *.lock files around.
`nix-daemon`'s journal logs contained crashes like:
nix-daemon[30416]: terminate called after throwing an instance of 'nix::SysError'
nix-daemon[30416]: what(): error: writing to file: Broken pipe
And core dump backtraces pointed at `teriminate()` call from
destructors:
...
_Unwind_Resume ()
nix::ignoreException() ()
nix::LocalDerivationGoal::~LocalDerivationGoal()
...
void ignoreException()
{
try {
throw;
} catch (std::exception & e) {
printError("error (ignored): %1%", e.what());
}
}
The crashes happen when client side closes early and printError() throws
an IO error.
The change wraps `ignoreException()` into blanket `try { ... } catch (...) {}`.
