| 04:42.16 | brlcad | nope, you're right .. you don't |
| 04:42.33 | poolio | is this a freenode thing? |
| 04:42.50 | brlcad | no, it's an account on the project server |

| 04:43.29 | brlcad | machine's fqdn is bz.bzflag.bz but is aka my.brlcad.org among other names |
| 04:43.45 | brlcad | .bz or mbo for short |
| 04:44.00 | poolio | alright. and what type of access am I getting / how can I use it? |
| 04:44.39 | brlcad | it's a pretty comprehensive account with a lot of resources |
| 04:45.01 | brlcad | details and rest of setup in priv |
| 05:38.25 | brlcad | got it |
| 05:38.30 | poolio | alright |
| 05:38.31 | brlcad | and nah, it's fine |
| 05:38.37 | poolio | k |
| 05:39.14 | poolio | can you see the issue or would you like a little explanation? |
| 05:39.26 | poolio | the issue might just be me misunderstanding how the lookup/internal routines work |
| 05:46.32 | poolio | I previously used rt_db_lookup_internal instead of db_lookup/rt_db_get_internal but moved to the latter in hopes of eliminating the error/issue |
| 05:53.28 | brlcad | ahha |
| 05:53.39 | poolio | uh oh. |
| 05:53.49 | brlcad | the same reason that db_rename wouldn't work for you, similar exists for renaming that dp you looked up |
| 05:54.19 | poolio | but how? I thought renaming the dp only changed the dp, how is it effecting the in-memory db? |
| 05:54.41 | brlcad | the db_i holds the directory |
| 05:55.02 | brlcad | db_lookup scans the directory hash in the db_i, and returns the pointer to that directory pointer |
| 05:55.16 | brlcad | so when you modify it, you've modified the current db_i |
| 05:55.20 | poolio | ahhh |
| 05:55.34 | poolio | so is there any way around it other than changing the dp back to the original name? |
| 05:55.45 | brlcad | hence the next lookup fails, because the entry is no longer in the directory hash |
| 05:56.46 | brlcad | let me see if I can find it, there's a few ways to get a copy |
| 05:57.23 | poolio | a copy of the dp? It seems like it's just as efficient to copy the name, change the name, write to new database, change the name to original name |
| 05:59.10 | brlcad | hm? |
| 05:59.21 | brlcad | the dp is an entry from the first db_i |
| 05:59.40 | brlcad | if you modify it in any way, you're modifying the directory for the first db_i (which you probably don't want) |
| 06:00.08 | poolio | correct. so in terms of most efficient / least space, wouldn't it make the most sense to just rename it and then change it back to its original name? |
| 06:00.21 | poolio | well I don't really want that, but it's acceptable |
| 06:02.15 | brlcad | hm, that might work, but you'd probably need to dig a little deeper into db_put_internal to be certain |
| 06:04.08 | brlcad | the approach taken elsewhere is to do the lookup on A to get the dp, do a db_get_external for his representation, do a db_diradd on B (which gives you a new dp), then db_put_external to write the copy |
| 06:04.22 | brlcad | that same approach should work for internal format too |
| 06:06.34 | brlcad | the issue with the internal, though, is that it keeps track of the object's offset in the file, so need to make sure db_put doesn't use it |
| 06:07.13 | poolio | although that solution looks more elegant it looks to be a lot more overhead :) |
| 06:07.43 | brlcad | these are all pretty lightweight calls |
| 06:09.53 | poolio | ah. I get the offset problem anyway, both calls work but I guess the internal objects have the same offset |
| 06:12.06 | poolio | so how would I go about fixing the offset issue? just keep a counter of what offset we're at in the database? |
| 06:12.53 | brlcad | hm, i was actually just looking at put_internal and don't see where offset would be a problem |
| 06:13.10 | poolio | well in my updated test case only the second object appears |

| 06:14.14 | brlcad | ah, never mind, I found it |
| 06:17.37 | brlcad | yeah, you're going to have to use what I'd said |
| 06:17.55 | brlcad | get the external form, write that out into the second after doing a db_diradd |
| 06:19.52 | poolio | hmm. I can't seem to remember why I was using internal anyway...I'll have to read the structs later |
| 06:20.20 | brlcad | see src/librt/wdb_obj.c:2973 for an example that does this in a single db_i, but should work almost as-is for two db_i's |

| 21:23.51 | poolio | The linDiff function wasn't working quite right |
| 21:23.57 | poolio | and then I tried to get it to work using just reproduction but that failed |

| 21:24.18 | brlcad | ah, not yet |
| 21:24.19 | poolio | Once all that is working I'll test it out |

| 21:24.28 | poolio | Just pick two nodes on two trees, and swap them |
| 21:24.46 | brlcad | easy as pi |
| 21:24.48 | poolio | or pick a node on one tree, and a node on the second, and move the node from the firs tree to the node on the second, wiping out the node on the second |
| 21:24.57 | poolio | Well it seems pretty easy not that it's in a nice tree format |
| 21:25.15 | poolio | mutation is what's going to be the pain -- writing a case for each shape, modifying the specific data, etc... |
| 21:25.33 | brlcad | swapping nodes with a percentage of new "material injection" should do the trick |
| 21:25.37 | poolio | once all that is up and going a lot of work is going to be put into tweaking the GA, modifying the approach a little, etc... |
| 21:25.56 | poolio | not sure what you mean by new material injection? |

| 21:26.27 | poolio | Well, I can try that too. Would be interesting, and it's closer to the standard bit string encoding |

| 21:33.02 | brlcad | btw, i was entirely kidding about tweaking the encoding bits -- almost certainly would not work as the encoding is not like "standard bit string encoding" as there are massive subsets of bit manipulations that are "poison" in that they would represent geometry that is entirely "impossible"/invalid/useless |
