quick, who of those discussing the slowness of exceptions has benchmarked exceptions recently?

well, no need to scamper to your compilers to whip up some microbenchmarks because I already did that, and the results are:
pre:
100_000_000 repeats of trivial work done, 50% errors:

method 1, boolean return          took  667 ms,  result was 3
method 4, reused flow exception   took  752 ms,  result was 3

a mere 10% slowdown for the privilege of using some dodgy flow control as part of the normal execution path

lol java programmers

also

quote:

method 3, option type wrapper took 910 ms, result was 3

there should be no reason for an option type to be significantly slower than returning a value + a bool indicating if its valid. java is awful

allocating memory on the stack (which is how value types too large to fit into registers are returned in c++) pretty much is: it is literally nothing more than an addition

it makes sense though, option types you have to first allocate a new one, then check what it contains, when exceptions give you the second part for free

"One true form of exception handling", to me, sounds as reductionist of an approach as "one true form of concurrency", "one true programming language paradigm", or whatever. This is to say, it's perfectly fine to be opinionated about it and kitchen sink languages might be terrible, but there will be areas where one or more of them is better than some single other.

...

Treating all error conditions / exceptions with the same mechanism will generally ensure that you pick similar stances on encapsulation vs. detection and identification for all error conditions / exceptions, unless you decide to be extra careful about all of that.

Using multiple mechanisms will allow you to pick, case by case, which one you feel is worth breaking depending on the nature of the fault and what your specific application or system requires.

Option types are pretty awesome, but they're not blanked replacements for other mechanisms IMO. Context is king.

In my previous job I did both development and (a lot of) field support. At any moment day or night during my support weeks, a page could come in and then I would have to:

- Power up my cheap company-provided Thinkpad with its pointing stick :stonk:

and impossibly small display
- Jump onto the company VPN and connect to my Linux box at the office
- Query the on-site databases in SQLPlus, grep through tool logs, and review tool source code to find out what the hell might be breaking
- Draw on a library of scripts that I had created over time to speed up the process.
- Keep the entire session alive as I moved between home and the office.

Relying on an IDE under these constraints was just hopeless so I used screen + emacs. When I went interviewing for the next job and told people that I had been using emacs for development, none of them gave a poo poo whether I had used anything else in earlier jobs or there might be a practical reason behind it. It could only mean that I was a "hard-core hacker."

put your dotfiles in a git repo, store it in bitbucket. when you get a new machine clone the repo and symlink stuff to ~

Max Facetime posted:

does this ever turn into wildly cascading failures waves as each part tries to figure out which other parts they can trust to be working correctly while the whole system shifts and settles to a new consensus view of the world?

The gist of it is that if you know how to deal with a given other part failing, you do it and it won't cascade. Otherwise you may fail yourself. This can lead to cascading failures, but that's only a consequence of your program not knowing how to work with missing components. Do note that this cascading failure, in the worst case, stops all program execution the way a regular exception in a single-process program kills the entire flow of the system and shuts things down or forces a restart of part of the flow.

This leads to trying to develop more modular and loosely coupled components, each in their own process, because the bits you can live without, you design to be entirely separate -- their failure shouldn't affect your own process. How this succeeds or fails in practice is scientifically unproven, I guess. I personally like it.
