If it was just subversion then I'd consider patching that. But it's wider
and seems a bit silly to patch all over the place .. Looks like mozillas
have a hard exit in some cases -
// Ensure that we are using the same version of SQLite that we compiled with
// or newer. Our configure check ensures we are using a new enough version
// at compile time.
if (SQLITE_VERSION_NUMBER > ::sqlite3_libversion_number()) {
nsCOMPtr<nsIPromptService> ps(do_GetService(NS_PROMPTSERVICE_CONTRACTID));
if (ps) {
nsAutoString title, message;
title.AppendLiteral("SQLite Version Error");
message.AppendLiteral("The application has been updated, but the SQLite "
"library wasn't updated properly and the
application "
"cannot run. Please try to launch the application
again. "
"If that should still fail, please try reinstalling
"
"it, or visit https://support.mozilla.org/.";);
(void)ps->Alert(nullptr, title.get(), message.get());
}
MOZ_CRASH("SQLite Version Error");
}
- freeradius has a tighter dependency but at least is only a warning:
if (sqlite3_libversion_number() != SQLITE_VERSION_NUMBER) {
WARN("rlm_sql_sqlite: libsqlite version changed since
the server was built");
WARN("rlm_sql_sqlite: linked: %s built: %s",
sqlite3_libversion(), SQLITE_VERSION);
}
