2022-02-21util: Add SaturatingAdd helperMarcoFalke
2022-02-04Re-enable util_datadir check disabled in #20744Ryan Ofsky
This should also fix an assert error if a -datadir with a trailing slash is used on windows. This appears to be a real error and regression introduced with #20744. On windows (or at least wine), fs calls that actuallly access the filesystem like fs::equivalent or fs::exists seem to treat directory paths with trailing slashes as not existing, so it's necessary to normalize these paths before using them. This fix adds a path::lexically_normal() call to the failing assert so it passes.
2022-02-03refactor: replace boost::filesystem with std::filesystemKiminuo
Warning: Replacing fs::system_complete calls with fs::absolute calls in this commit may cause minor changes in behaviour because fs::absolute no longer strips trailing slashes; however these changes are believed to be safe.

2022-01-11util: Restore GetIntArg saturating behaviorJames O'Beirne
The new locale-independent atoi64 method introduced in #20452 parses large integer values higher than maximum representable value as 0 instead of the maximum value, which breaks backwards compatibility. This commit restores compatibility and adds test coverage for this case in terms of the related GetIntArg and strtoll functions. Co-authored-by: Ryan Ofsky <ryan@ofsky.org>

Instead of running into an integer overflow in an unused result, don't calculate the result in the first place. Other code paths (using the active utxo set) can not run into an integer overflow, since the active utxo set is valid.

Implicit conversions like this are not great in general because they can hide complexity and inefficiencies in the code, but this case is especially bad, because after the transition from `boost::filesystem` to `std::filesystem` in #20744 the behavior of this constructor on windows will be more complicated and can mangle path strings. The `fs::path` class also has a `.string()` method which is inverse of the constructor and has the same problems. Fix this by replacing the unsafe method calls with `PathToString` and `PathFromString` function calls, and by forbidding unsafe method calls in the future.

2021-10-05refactor: Block unsafe fs::path std::string conversion callsRussell Yanofsky
There is no change in behavior. This just helps prepare for the transition from boost::filesystem to std::filesystem by avoiding calls to methods which will be unsafe after the transaction to std::filesystem to due lack of a boost::filesystem::path::imbue equivalent and inability to set a predictable locale.
