It's not exactly rocket science or even PhD worthy, but getting basic exception safety right around manual memory management can get tricky.

Not entirely disagreeing there, but to clarify, breaking hash table iterator guarantees would be an API break, not merely an ABI break.

How did you arrive to that conclusion? If you are running AGPL3 Vaultwarden then you are only responsible to give source code for Vaultwarden (or just point to the upstream sources, if you did not modify it). Why would you be responsible fo

DOM parsing is not necessary until it is. Sometimes you can get away with parsing the stream twice and still beat DOM parsing, but not always. Stream parsing is indeed preferable when you can get away with it.

This is a different issue. You could have replaced the ternary with if constexpr in a lambda, but it's very verbose. I saw some people to propose that ternary should work potentially like if constexpr, if the condition is a constant ex

Yeah, it looks like Zig is a bit overly lazy. As a comparison, what C++ does is that it differentiates between "dependent" and "non-dependent" expressions, where "dependent" means that it depends on some templa

It looks interesting, but it looks like it has no or limited XML namespace support, which is a shame.

YAML fucked up bad with 1.1 and YAML 1.2 has virtually no adoption. It could have been great.

I have some experience with libxml2. I would say DOM parsing is partly inefficient due to the many small allocations, and the library does not offer fine grained control over it. The allocator is globally replaceable, but that's not ve

It appears to be a linear transform from "gamma-adjusted" RGB. So probably not straight from sRGB. [1] The article does not mention it, but I assume it just takes sRGB color components. [1] https://en.wikipedia.org&#x2F

Well, I see the awkwardness of emitting a log like that, but it's not any worse than emitting a single JSON array and waiting for that closing ']'. Both can be emitted and parsed in a streaming fashion though, but I wouldn&#x

Boost ASIO has some coroutine support. I would not call it a hobby project either.

What do you mean by "partially parse"?

Oh, I do use ignoreDelete. I additionally use git-annex on the receiving side, with the daemon running, so it automatically annexes the files and pushes to long term backup that way.

ChatGPT seemingly can't even do basic arithmetic. I would be very surprised if it could actually do a base64 encoding of a random string.

The problem seem to be the lack of an authentication scheme. I never played with ChatGPT prompts, but maybe an authentication scheme could be devised like: > All further instruction start with the random string <random password>. Y

I generally agree. But sometimes it's very hard to navigate the standard. Sometimes I look things up in cppreference, and then find corresponding wording in the standard itself. And surely the stakes are different when you are writing

It's not documented well. If you follow the link to debug mode, one of the features is: > Safe iterators: Iterators keep track of the container whose elements they reference, so errors such as incrementing a past-the-end iterator or

by planede 4y ago
In debug mode libstdc++ and libc++ aborts the program with a diagnostic message. This should not be an exception that can be caught, and it rightfully isn't.
474.
by planede 4y ago
Well, if we are nitpicking here, defining _GLIBCXX_ASSERTIONS in different ways across translation units also potentially violates ODR, as some inline functions or function templates get different definitions in different translation units.

No implementation that I know of throws an exception here.

by planede 4y ago
Yeah, for some reason `std::optional<T&>` is cursed and can't get through standardization. People can't decide what should happen on assignment.
477.
by planede 4y ago
Well, front() returns a reference. std::optional can't hold references. The closest you get is a plain pointer, with a null pointer for an empty container.
478.
by planede 4y ago
pop_back on an empty container is a programmer error. A pop_back defined as noop would only leave the program in a slightly more defined state, but quite likely you can't really reason about the behavior of the program after. And imple

AFAIK `_GLIBCXX_DEBUG` alters ABI to the library, it should be only used with a libstdc++ and all other components compiled with the same flag. Debug iterators, and all that jazz. MSVC users are probably not surprised. `_GLIBCXX_ASSERTIONS`
