| 02:15 | kid51 | jeez, has it been quiet here this week/month/weeks since last release! |
| 02:17 | GeJ | blame it on global warming. It's way too hot to do anything productive. |
| 02:18 | kid51 | Actually, in most of NA and Europe we've been freezing our cojones off! |
| 02:18 | Those few of us who started with any cojones ;-) | |
| 02:20 | GeJ | A coworker of mine just returned from one month in France. Boy was he happy to be back. |
| 02:23 | Weather forecast anounces that it'll be ~80�F tonight. That's the annoying part. | |
| 02:24 | I don't mind a hot day, but I like my nights cool. | |
| 02:28 | Parrot's next release is scheduled for this week, right? | |
| 02:39 | kid51 | Yes, this tuesday |
| 02:39 | Crude measure of (in)activity: 2009-11-15 to 2009-12-14: 450 commits to trunk -- but only 194 to date since then | |
| 02:40 | GeJ? Do you know anything about PMC stuff like PARROT_ASSERT? | |
| 02:41 | GeJ | I'm totally igorant on the subject. Sorry. |
| 02:41 | kid51 | Anybody on channel who can comment on http://trac.parrot.org/parrot/[…]et/1382#comment:3 ? |
| 02:46 | GeJ: Have you been submitting smoke reports? On BSD? | |
| 02:47 | GeJ | yup, I did a couple of them last week. |
| 02:47 | kid51 | Bravo! Was that FreeBSD? |
| 02:48 | GeJ | Although, I suspect I'm not the only one. After I submitted two of them I went to the web interface only to discover that the last 3 smoke tests were on FreeBSD. |
| 02:48 | abqar joined #parrot | |
| 02:49 | GeJ | Also, I'm starting to scratch my head to update parrot for the next release. And eventually creat a rakudo port. |
| 03:00 | plobsing_ | kid51: those assertions check that the pointers are aligned to a 2**n char boundary (required on some obscure platform I'm sure). on the one hand, parrot doesn't check this elsewhere; on the other, UnManagedStruct is the closest users come to directly managing pointers, so extra checks might be good. |
| 03:05 | kid51 | plobsing_: Assuming that the point is to get rid of PARROT_PTR_ALIGNMENT (and enable us to get rid of config step auto::alignptrs), what would be the safest way to rewrite lines 188 and 202 in src/pmc/unmanagedstruct.pmc |
| 03:05 | ? | |
| 03:06 | plobsing_ | well, I'm not certain of the specific requirements, but I would guess that the required alignment is platform-specific |
| 03:06 | kid51 | i.e., as an alternative to simply deleting those lines (which appears to cause no harm in that branch), what would you do? |
| 03:07 | plobsing_ | to get the information required for that check, you'd have to probe the platform for minimum pointer alignment (which is what auto::alignptrs does AFAICT) |
| 03:08 | we could say: if you run a platform that breaks if you access pointers that aren't aligned and you break it using UnManagedStruct, that's your fault | |
| 03:08 | in a way, UnManagedStruct is part of the escape hatch of the VM abstraction | |
| 03:08 | kid51 | What's the significance of this part of those lines: (PTR2INTVAL(p) |
| 03:08 | PTR2INTVAL(p) | |
| 03:09 | plobsing_ | thats a cast from pointer to integer, in a very (overly maybe?) general, safe way. |
| 03:09 | kid51 | ok. Now, what's PARROT_ASSERT |
| 03:09 | plobsing_ | abstraction over assert() |
| 03:10 | kid51 | Is assert() a C function? |
| 03:10 | plobsing_ | yes. panics if its argument isn't true |
| 03:19 | kid51 | May I paraphrase you in the TT? Am seeking comments from all knowledgable sources. |
| 03:20 | plobsing_ | sure. I don't know when I became a knowledgable source though. |
| 03:26 | kid51 | Thanks. |

| 22:20 | Whiteknight joined #parrot | |
| 22:21 | Whiteknight | how we doing for the release? |
| 22:22 | plobsing joined #parrot | |
| 22:22 | darbelo | OpenBSD is failing t/pmc/io.t test #22 |
| 22:23 | But only in 'make test' prove doesn't show it. | |
| 22:28 | Whiteknight | urg |
| 22:29 | darbelo | backtrace at http://nopaste.snit.ch/19292 |
| 22:32 | I dislike backtraces that end with a call to memmove() | |
| 22:33 | Whiteknight | when did yeah, srsly |
| 22:35 | darbelo | But then OpenBSD's utterly paranoid memory management means I get more of those than everyone else. |
| 22:35 | And, I think... I fixed it? | |
| 22:37 | Whiteknight: http://nopaste.snit.ch/19293 | |
| 22:37 | Does that make sense to you? | |
| 22:40 | Whiteknight | reasonable |
| 22:40 | purl | reasonable is definitely not sungo. |
| 22:40 | Whiteknight | I would need more time to really evaluate it |
| 22:43 | darbelo | The surrounding code points to that. (fetch _next, memmove() to _start, increment _ext?) But I find it odd that such and odd bug would only surface now. |
| 22:48 | And all other memmoves()s are done on buffer_next... | |
| 23:06 | Aha! Parrot_io_flush_buffer() does a Parrot_io_set_buffer_next() to the right place. | |
| 23:06 | I still wonder why this is only coming up now, however. | |
| 23:07 | plobsing | darbelo: how many people are currently using Parrot for heavy IO? |
| 23:07 | that might explain how this bug went undetected | |
| 23:08 | darbelo | I'm not doing heavy IO eoither, and it hasn't bit me before. |
| 23:11 | plobsing | what baffles me is how buffer_start comes out of sync with where the filehandle's buffer is. |
| 23:14 | darbelo | Yeah, in particular as Parrot_io_flush_buffer() sets buffer_next (which works) to be tha same as buffer_start (which explodes) |
| 23:16 | *something* makes the pointer stored in the PMC change. But I can't find what it is. | |
| 23:17 | plobsing | could you step through with gdb? |
| 23:17 | it's 100 lines, but most of it is conditionals that won't get taken | |
| 23:18 | darbelo | Not really, it only gets triggered on 'make test'. I can't make it happen out of the test harness. |
| 23:19 | plobsing | can't you run parrot with the same flags? |
| 23:19 | darbelo | AFAICT I have. |
| 23:19 | plobsing | darbelo: are you running the test suite in parallel? sometimes thread pressure has caused some tests to fail for me (though those were mostly threading-related) |
| 23:20 | darbelo | nopes, just plain ol' "make test" |
| 23:22 | Hmm, gimmie a sec. I have an idea. | |
| 23:22 | kid51 joined #parrot | |
| 23:24 | * kid51 | reads backscroll |
| 23:26 | kid51 | darbelo: the behavior you were describing in t/pmc/io.t on OpenBSD earlier sounds a lot like the "happens during make test but not prove" behavior we saw in the early stages of this ticket: http://trac.parrot.org/parrot/ticket/1393 |
| 23:27 | What happens if you run: perl t/harness --gc-debug t/pmc/io.t ? | |
| 23:28 | darbelo | kid51: works fine. |
| 23:31 | kid51 | That's with or without your patch in http://nopaste.snit.ch/19293 ? |
| 23:31 | darbelo | both :) |
| 23:32 | kid51 | Hmm, scratch that hypothesis :-( |
| 23:33 | plobsing | what does --running-make-test do? |
| 23:34 | darbelo | makes the test fail for me, apparently. |
| 23:35 | http://nopaste.snit.ch/19294 | |
| 23:39 | But it doesn't happen on every run. That was throwing me off. | |
| 23:40 | Which means that my fix was wrong. | |
| 23:40 | It's the buffer that's pointing into never-never land. | |
| 23:41 | My guess is that the string pool is getting compacted from under us. | |
| 23:41 | plobsing | yay! more gc "fun" |
| 23:41 | darbelo | The io functions like to play with raw pointer into strings. |
| 23:42 | plobsing | darbelo: run the test with '-R gcdebug' |

| 23:44 | preflex joined #parrot | |
| 23:45 | kid51 | What I'm unclear about is this line in t/harness: $ENV{RUNNING_MAKE_TEST} = $longopts->{running_make_test}; |
| 23:46 | I don't know what setting that environmental variable does. | |
| 23:47 | plobsing | kid51: yeah, I don't see any effect it should be having on TAP::Harness |
| 23:47 | kid51 | And I doubt this inline comment in config/gen/makefiles/root.in: # The --running-make-test argument is currently used by long-running tests to disable GC_DEBUG. |
| 23:48 | plobsing | remove it and see what breaks (post-2.0) |
| 23:50 | kid51 | Googling RUNNING_MAKE_TEST only brings up Parrot links -- many of them by me! |
| 23:50 | So it doesn't appear to have anything intrinsically to do with 'make'. | |
| 23:51 | * kid51 | will create branch to explore this |
