| Geth | MoarVM: 72befa1647 | (Timo Paulssen)++ | src/jit/core_templates.expr The exprjit of sp_bind_o caused wrongness even though the sp_bind_o looked correct to many eyes. we expect the problem is something that used to not go through the exprjit because sp_bind_o caused the exprjit to bail out earlier is now active |
00:10 | |
| timotimo | damnit, the other stuff got merged into moar master directly after the bump | 00:19 | |
| so i'll have to also revert that and re-revert it back | |||
| Geth | MoarVM: b2dc3f3ba2 | (Timo Paulssen)++ | 19 files Revert "Merge pull request #1139 from MasterDuke17/add_context_to_error_messages" This reverts commit bfe499dd6b891bc5101543337a7082ad356d0b16, reversing changes made to 2ac137c3d879e7e77c37522fcd7661fd9e4f6203. |

| timotimo | really gotta look into this "coz compiler" thing | 00:43 | |
| especially seeing if we can steal the way it works and put it into moarvm | 00:44 | ||

| timotimo | uh oh, looks like more than just sp_bind_o is wrong | 10:48 | |
| i wonder if i should revert all of them for now and put them into a branch | 10:49 | ||
| nwc10 suggests | |||
| 1) step away from the keyboard | |||
| 2) make coffee (or something) | |||
| 3) ponder this | |||
| and after a delay, see if you have the same answer in your head | |||
| timotimo | i've just been away from the keyboard for a whole bunch of hours :P | ||
| nwc10 | aha. pre-delayed | 10:50 | |
| as to the actual question, I don't know | |||
| timotimo | i regularly stock up on away-from-keyboard time | ||
| nwc10 | I'm not sure what I'm going to do for away-from-keyboard time once I've finished flattening the garden | ||

| nine | timotimo: moving them off into a branch would indeed be nice for others who work on the VM. Especially since they cause mysterious and hard to reproduce issues. | 11:53 | |
| Geth | MoarVM: 986e05beab | (Timo Paulssen)++ | 2 files Revert "exprjit sp_p6oget_bi" This reverts commit 0674a1e6940e8c7945dd6e5620ad3edc28414f43. |
11:56 | |
| MoarVM: a0ff25c746 | (Timo Paulssen)++ | src/jit/core_templates.expr Revert "exprjit: templates for sp_get_i* and sp_get_o" This reverts commit acfb5949967065694a058a31c159f99bfb730469. |
|||
| nine | Oh, I think I misdiagnosed the spesh plugin race condition issue. I thought that resolve_using_guards was using a plugin_state that was already freed by a concurrent add_resolution_to_guard_set. But this already uses MVM_fixed_size_free_at_safepoint. | 12:39 | |
| I bet what actually happens is that this old plugin_state is no longer anchored somewhere where the GC would find it, so the guards it contains can become outdated. | 12:41 | ||
| Usually it would hang off the MVMStaticFrameSpesh but add_resolution_to_guard_set replaces it with the new version. | 12:42 | ||
| The bad news is that this is not just a case of adding an MVMROOT and be done with it. The good news is that this is still in the realm of problems that I know how to solve :) | 12:44 | ||
| Guest15407 | timotimo: your templates are probably good, the problem lies elsewhere | 12:49 | |
| timotimo | yeah, but making them available causes trouble | ||
| Guest15407 | true true :) | ||
| nine: what do you make of os_handle here? github.com/MoarVM/MoarVM/blob/mast...ops.c#L496 | 12:50 | ||

| MasterDuke | timotimo: why did my PR merge have to be reverted? couldn't just the template commits have been reverted and then a new bump? | 16:46 | |
| timotimo | then the bump would have had the merge in it, too | 16:47 | |
| MasterDuke | also to everybody, my bad on asking for the bump in the first place | ||
| timotimo | but the merge was specifically delayed after the bump | ||
| MasterDuke | oh, ha. right | ||
| heh, forgot about that. timotimo++ | |||

| nine | It occured to me that I totally wasted those GC fixes I did. I could have kept a pile of them, just pushing one per week and ensure my mention in the weekly for almost a year in advance! Then I could have become known in the community as the possibly corrupt memory guy...or....wait...nah, better not :D | 18:04 | |
| MasterDuke | so many different options for hyphens to change meaning there: possibly-corrupt memory guy, possibly corrupt-memory guy, possibly corrupt memory-guy, possibly corrupt-memory-guy, possibly-corrupt-memory guy, possibly-corrupt memory-guy, possibly-corrupt-memory-guy | 18:08 | |
