| dalek | arVM: f12710c | paultcochrane++ | .travis.yml: Change Travis matrix option to --no-jit This is because JIT is on by default, thus only the JIT was being tested in all configurations. It was also throwing the warning that --enable-jit was obsolete and mentioning the --no-jit option, which would make sense so as to test with and without JIT. |

The nqp tests pass and this seems correct in this situation, however a code review would be a good idea to be on the safe side. |

| jnthn | On 0afe1e0, any code reading those fields when the box type is reference is wrong anyway; they're meaningless whatever values they have in that case. | 06:28 | |
| So, wasn't a bug, but don't mind the patch. | 06:29 | ||
| 56dcbaa is curious in that it's C89 we're targetting. | |||

| nwc10 | jnthn: "Implement a more compact varint serialization format" isn't quite correct | 07:42 | |
| I think it's usually *less* compact. | 07:43 | ||
| (slightly) | |||
| but it uses less CPU | |||
| it will be more compat for values between 64 and 126 | |||
| jnthn | nwc10: Better wording? "more efficient" :) | 07:45 | |
| nwc10 | Yes, that seems bnetter | 07:47 | |

| lizmat wonders how interesting www.liblfds.org would be for MoarVM ? | 07:55 | ||
| probably not, as it is already 2.5 years old :-( | 07:56 | ||
| sorry for the noise | |||
| jnthn | lizmat: Well, code doesn't rot with age :) | 07:57 | |
| lizmat: It looks familiar, I'm sure I've looked over it before | 07:58 | ||
| lizmat: But it's quite restricted | |||
| e.g. | |||
| "hash (add-only)" | |||
| FROGGS | wasn't there an intend to to something (replace) uthash? | ||
| jnthn | At some point, yes. | 07:59 | |
| FROGGS | why ooc? is it inefficient? | ||
| jnthn | It could be more memory efficient, but more notably it's missing sufficient randomization. | 08:00 | |
| FROGGS | ahh jnthn, before I forget... can you look at my question from yesterday? irclog.perlgeek.de/moarvm/2015-04-22#i_10484760 | 08:01 | |
| ahh | |||
| I always wonder why we want to have randomization at all | |||
| jnthn | Check for matching SC - yes | ||
| Randomization - thwart DoS attacks | |||
| FROGGS | where are these checks? | 08:02 | |
| jnthn | See write_obj_ref | ||
| Well, actually it's not "check for matching SC" | |||
| It's "check for no SC and put it into the current one if so" | |||
| FROGGS | ahh, nice | ||
| that is what I was looking for | |||
| I was thinking the check happens earlier | 08:03 | ||
| jnthn | I think "packed" is the thing what nwc10++ added recently so we can store things more compact. :) | ||
| No, happens during traversal | |||
| FROGGS | I see | ||
| veeeery nice... so I can continue now :o) | 08:04 | ||
| jnthn | \o. | ||
| \o/ even | |||

| nwc10 | Given that MoarVM isn't using shared hash keys, I suspect that randomisation could be added by storing a small (eg) 32 bit salt value for each (and every hash) | 08:15 | |
| with the salt coming from a private drand48() or similar | 08:16 | ||
| ie, not much effort needed | |||
| because, as best I can tell/remember, the actual integer hash values are not exposed outside of the hash table code | 08:17 | ||
| masak | jnthn: thank you :) | 08:33 | |

| jnthn | Yeah, missed the native ref opts. The parameterics serialization got done, and NFG is basically there. | 14:14 | |
| Not wired up everywhere, but the key algos are in place. Plus we got all /NFK?[D|C]/ too and an update to Unicode 7 :) | 14:15 | ||

| brrt | yes :-) and all positive | 15:53 | |
| i'd better start reading intel docs then :-) | |||
| i think what you said about using the jit as a stepping-stone as it were for small-bigints, nativecall, etc.. that has a lot of potential | 15:55 | ||
| jnthn | *nod* | ||
| Well, they also can produce expression trees. | 15:56 | ||
