See (just a quick example): https://stackoverflow.com/a/43050919/184064 This is still not an ideal solution, but it illustrates some of issues which can arise. Having a website in PHP around 2001 has taught me that writing to a file in a HTTP environment filled with crawlers, bots, people holding F5 and slow clients, is vastly different than writing to a file on a single-user system. > If you have a markup language for your database it's bloat.

The above is an extreme example, but *any* character that has special meaning to shell can cause problems. You should instead look into exec and/or posix_spawn functions before going any further. Yes, this, system() is most of the time both the wrong way and the hard way. Created a PR[0] to demonstrate how to use posix_spawnp() instead. Also, as a sidenote; there is no C--, there's nothing -- about C. [0]: https://github.com/equwal/swallow-c--/pull/2 -- Santtu

Re: [dev] running a shortlink provider
Hi, Just my two cents, but why not just store the link destination, even better, the HTML with the correct re-direction, in a file named according to the hash. You can then just serve it as-is. No lock problem. No database required. O(1) complexity. Of course this is only valid for a personal, non-public use since that strongly limits the number of links you can have. Also, this is trivially extensible to a pastebin. - syg

The above is an extreme example, but *any* character that has special meaning to shell can cause problems.
