Gergely Nagy	2bfc4c81a8	metrics: Implement iocaine_maze_depth ... Signed-off-by: Gergely Nagy <me@gergo.csillger.hu>	2025-03-04 14:05:35 +01:00
Gergely Nagy	fd1530707e	A complete rework of metrics ... Drop `metrics` and `metrics-exporter-prometheus` in favour of `prometheus`, and completely reimplement how metrics are done. This gives me much more control over them, and also makes process-based metrics available as a bonus. Signed-off-by: Gergely Nagy <me@gergo.csillger.hu>	2025-03-04 13:24:50 +01:00
Gergely Nagy	406f8e0f80	metrics: Add labels to iocaine_garbage_served ... Lifted out the label construction code into its dedicated function, so it can be reused to add labels to `iocaine_garbage_served` too. The required information is at hand at that point, so the cost of doing this is minimal. Changelog & Grafana dashboard adjusted accordingly.

Gergely Nagy	d291d508cb	Merge a few functions ... There's no need to have `poison()`, `poison_root()`, and `poison_path()`: it is enough to have one, and mark path as `Option<Path<String>>`, and supply a default. Signed-off-by: Gergely Nagy <me@gergo.csillger.hu>	2025-02-24 22:46:48 +01:00

Gergely Nagy	d2f23ec9c8	Merge pull request 'Do less allocating and copying when generating text' (#9) from iadd/iocaine:optimize-markov-generation into main	2025-02-10 17:19:17 +00:00
iadd	284af56e68	Do less allocating and copying when generating text ... Before, on a low-capacity system (such as a an inexpensive cloud host), doing Markov-chain text generation was _extraordinarily_ slow, taking half a second or more to produce a page, and if multiple requests came in simultaneously they could easily swamp the capacity of such a system. Most of the time was spent in the Words iterator, which did a bunch of cloning of Strings in what the hot path. This changes the Markov generator's internal representation - now, instead of storing Strings, it stores index-pairs into a single shared String, normalized so that all references to particular words are collapsed into a single pair. This also means that the hash map is working with fixed-size values, which can't hurt. In addition, it does only one hash-map lookup per generated word in the happy-path of not reaching the end of the chain. The upshot of all this is that where it was taking a half-second or more to generate a page, it now takes about 0.001 seconds. On the downside, the initialization of WurstsalatGeneratorPro has become rather less flexible. Before, you created one and then taught it various strings, or gave it a list of paths to read and teach itself from. Now, the _only_ way to create one is directly with a list of paths. Changing this is possible, but it means `Substr` would have to learn to distinguish which source data it came from, which would mean a likely 50% increase in its size. It didn't seem worth it to preserve that capability, which wasn't even being used.	2025-02-10 08:18:54 -08:00
