| timotimo | the only thing we're really using HLL for at the moment for the heap dump is turning the string heap into a json blob, fwiw | 23:02 | |
| that'd be doable in C, too. | |||
|

|
|||
| samcv | timotimo, what do we use that json blob for? | 23:20 | |
| timotimo | we're just using it for its escaping abilities, really | 23:21 | |
| samcv | oh | ||
| we could do thta in c | |||
| timotimo | yeah | ||
| samcv | what specifically do we use it for? | 23:22 | |
| timotimo | it stores every string the heap dump needs (no strings from the user program are in there, though) | ||
| samcv | m: use nqp; nqp::escape('\hi').say | 23:23 | |
| camelia | \\hi | ||
| samcv | m: use nqp; nqp::escape(Q’ \ \ / ' " _-abcd ’ ~ "\n").say | 23:24 | |
| camelia | ===SORRY!=== Error while compiling <tmp> Use of a closing delimiter for an opener is reserved at <tmp>:1 ------> use nqp; nqp::escape(Q⏏’ \ \ / ' " _-abcd ’ ~ "\n").s |
||
| samcv | m: use nqp; nqp::escape(Q‘ \ \ / ' " _-abcd ’ ~ "\n").say | ||
| camelia | \\ \\ / ' \" _-abcd \n | ||
| samcv | m: use nqp; nqp::escape(Q‘ \ \ / ' " _-abcd ’ ~ "\n\r\a" ~ "\x[0]").say | 23:25 | |
| camelia | \\ \\ / ' \" _-abcd \n\r\a␀ | ||
| samcv | doesn't escape null apparently | ||
| should it? | |||
| that seems pretty important | 23:26 | ||
| timotimo | not sure we can just use nqp::escape for that? | 23:27 | |
| like, will a json parser accept stuff with that? | |||
| samcv | you can't have \0 in json | 23:29 | |
| i mean | |||
| can't have the null character actually printed | |||
| so it's only supposed to escape for json? | |||
| m: use nqp; say nqp::escape('"') | 23:30 | ||
| camelia | \" | ||
| samcv | m: use nqp; say nqp::escape('\\') | 23:31 | |
| camelia | \\ | ||
| samcv | m: use nqp; say nqp::escape('/') | ||
| camelia | / | ||
| samcv | m: use nqp; say nqp::escape('"\ ' ~ "\0" ~ "\a") | 23:33 | |
| camelia | \"\\ ␀\a | ||
| samcv | timotimo, \a isn't a json thing... | ||
| so idk why you think it's a json escaper? | |||
| is it supposed to be? | |||
| m: '"'.encode.say | 23:34 | ||
| camelia | utf8:0x<22> | ||
| timotimo | it's not supposed to be a json escaper | 23:36 | |
| but the heapsnapshot contains a json list with only strings in it in the first line | |||
| if we create that with nqp::escape, it could get us into a little bit of trouble | |||
| samcv | trouble how? | 23:39 | |
| you mean instead of HLL? | |||
| because nqp::escape is not a json escaper? sorry a bit confused | 23:40 | ||
| timotimo | yeah, when you escape stuff with nqp::escape and write it to disk and a json parser tries to read it, things won't come out the same | 23:44 | |
| samcv | yeah of course | ||
| json escaper isn't that hard in C right | 23:45 | ||
| just look for characters | |||
