| 16:11.57 | seanbright | the real question is... how the hell will i know if linking with libhoard actually worked |
| 16:12.01 | seanbright | heh |
| 16:14.22 | tzafrir_laptop | seanbright, at runtime? |
| 16:14.27 | tzafrir_laptop | at build time? |
| 16:14.27 | seanbright | tzafrir_laptop: aye |
| 16:14.35 | seanbright | run time |
| 16:15.00 | tzafrir_laptop | well, you can always use 'pmap PID' as a last resort |
| 16:15.34 | tzafrir_laptop | err... that's for dynamic linking... for static: 'strings' helps |
| 16:16.01 | seanbright | its dynamically linked |
| 16:16.29 | seanbright | there is no static lib for hoard, apparently |
| 16:16.36 | seanbright | not that i have seen anyway |

| 22:30.34 | seanbright | anyone know what package to install to get libc_p.a on centos? |
| 22:32.53 | seanbright | hrmmm, no love from yum. |
| 22:34.32 | russellb | no clue what that is |
| 22:36.27 | seanbright | glibc + profiling foo |
| 22:37.33 | russellb | ~profile blah |
| 22:37.42 | seanbright | eh? |
| 22:37.50 | russellb | heh, was wondering if he had some witty comment for profiling someone |
| 22:37.58 | seanbright | heh |
| 22:39.35 | seanbright | yum search glibc-profile |
| 22:39.37 | seanbright | err |
| 22:40.37 | seanbright | ok, so its not in centos 5... *weak* |
| 22:40.55 | russellb | what do you want to profile? |
| 22:41.10 | seanbright | just this little program i am working on |
| 22:41.15 | seanbright | i call it... "asterisk" |
| 22:41.19 | russellb | :) |
| 22:41.36 | russellb | i figured that much ... but specifically |
| 22:41.39 | russellb | like, if it's the hoard stuff |
| 22:41.44 | seanbright | ohhh |
| 22:41.44 | russellb | i would just set up some load tests |
| 22:41.51 | russellb | try with it, and then without |
| 22:41.53 | russellb | but i'm kind of lazy |
| 22:42.10 | seanbright | the hoard stuff, yeah... i've temporarily diverted |
| 22:42.19 | russellb | specifically, try code paths that require a lot of malloc/free. |
| 22:42.20 | seanbright | call it a tangent |
| 22:42.20 | russellb | oic |
| 22:42.23 | russellb | hehe |
| 22:42.45 | seanbright | the hoard stuff requires makefile foo that will require stumbling on my part |
| 22:43.54 | seanbright | unless i take the cheapy way out and just set the env variable |
| 22:44.04 | seanbright | (LD_PRELOAD) |
| 22:44.23 | seanbright | but i would rather have all the obj files linked with it via make |
| 22:44.27 | russellb | nods |
| 22:44.46 | russellb | if you want to link the object files in, just add them to the list of OBJS in main/Makefile |
| 22:45.40 | seanbright | well, i meant more like -L/some/path/to/hoard -lhoard for everything |
| 22:45.46 | seanbright | not compiling hoard itself into asterisk |
| 22:45.52 | seanbright | but i guess that isn't a horrible idea |
| 22:45.58 | russellb | oh. |
| 22:46.04 | russellb | then i think there is an AST_LIBS variable |
| 22:46.07 | russellb | just add it to that |
| 22:46.15 | seanbright | k |
| 22:46.18 | seanbright | i'll give it a go |
| 22:46.33 | seanbright | seemed like a lot of ld related vars. solink, ast_libs, ldflags, etc. |
| 22:46.44 | russellb | brute force ... ASTLDFLAGS in top level Makefile |
| 22:46.56 | russellb | or AST_LIBS in main/Makefile |
| 22:46.56 | seanbright | m'kay |
| 22:46.58 | russellb | either will work |
| 22:47.49 | seanbright | heh... # ASTLDFLAGS - linker flags (not libraries) |
| 22:48.04 | russellb | :) |
| 22:48.09 | russellb | it would still "work" |
| 22:48.24 | seanbright | yes, it would. |
| 22:48.26 | seanbright | i'll give it a go |
| 22:48.51 | russellb | not something i would commit |
| 22:48.53 | russellb | but for testing |
| 22:49.01 | seanbright | well i would like to commit |
| 22:49.04 | seanbright | in my branch |
| 22:49.23 | seanbright | i'll figure out the "right" way to get it "working" after i test :) |
| 22:50.08 | seanbright | any magical way for me to look at a running process and see if it is using malloc in glibc vs. another lib? |
| 22:52.02 | seanbright | i'll even take a straight-forward way... magic optional |
| 23:01.50 | seanbright | bastardizing ASTLDFLAGS seemed to work |
| 23:07.34 | russellb | tzafrir had an idea earlier. i don't remember the command |
| 23:07.44 | russellb | pmap was it? |
| 23:08.49 | russellb | pmap -x `pidof asterisk` |
| 23:10.26 | seanbright | yeah |
| 23:10.31 | seanbright | that tells me what is linked |
| 23:10.40 | seanbright | i.e. the library |
| 23:10.47 | russellb | it tells you what is currently mapped into memory for that process |
| 23:10.55 | russellb | :) |
| 23:10.57 | seanbright | right... |
| 23:11.04 | seanbright | but i'm not that smart... |
| 23:11.06 | seanbright | heh |
| 23:12.32 | seanbright | i guess what i mean is, i see what is mapped, but how do i know that its actually using the malloc in hoard vs. the one in libc? |
| 23:12.35 | seanbright | by address? |
| 23:13.42 | seanbright | i have an idea |
| 23:15.02 | seanbright | ok, that didn't work. |
| 23:15.13 | seanbright | i'll just assume it's working. heh. |
| 23:18.20 | russellb | if it's there, it's pretty safe to assume it's working |
| 23:18.29 | seanbright | otherwise it wouldn't have linked? |
| 23:18.52 | russellb | because the way stuff gets resolved, is that it will check to resolve it in stuff that was linked as -lwhatever before implicit things like libc |
| 23:19.03 | seanbright | gotcha |
| 23:19.06 | seanbright | ok, i'll buy that. |
| 23:19.08 | russellb | same reason LD_PRELOAD works |
| 23:19.19 | russellb | because the resolver checks stuff from that first |
| 23:19.54 | seanbright | alrighty |
| 23:19.56 | seanbright | thanks |
| 23:20.08 | seanbright | i don't care what anyone says... you're pretty smart |
| 23:20.09 | seanbright | ;-) |
| 23:20.28 | Corydon76-dig | bonks seanbright on the head |

| 23:21.20 | Corydon76-dig | takes advantage of the situation |
| 23:21.26 | seanbright | wakes up and runs away |
| 23:22.16 | Corydon76-dig | concludes writing on seanbright with a permanent marker first |
| 23:22.23 | seanbright | russellb: if i get this to work as a configure/menuselect dealy, i can commit it to trunk, yeah? |
| 23:23.03 | Corydon76-dig | seanbright: should probably also test it under a variety of situations |
| 23:23.14 | seanbright | Corydon76-dig: of course |
| 23:23.30 | Corydon76-dig | That's a little beyond 'getting it to work' |
| 23:23.52 | seanbright | 'getting it to work... as a configure/menuselect dealy' |
| 23:23.58 | seanbright | meaning optional |
| 23:24.04 | Corydon76-dig | I've gotten things to work that, in hindsight, I probably should not have committed so soon |
| 23:24.55 | seanbright | i understand |
| 23:25.04 | Corydon76-dig | Cool |
| 23:25.16 | seanbright | commits |
| 23:25.17 | seanbright | heh |
| 23:35.50 | russellb | what is the license on hoard? |
| 23:35.55 | seanbright | gpl |
| 23:35.58 | russellb | and do you mean also including that source? |
| 23:36.01 | seanbright | no |
| 23:36.04 | russellb | k |
| 23:36.09 | seanbright | ./configure --with-hoard=/path/to/hoard |
| 23:36.41 | russellb | yeah, i think that's fine |
| 23:36.47 | seanbright | okie |
| 23:37.11 | russellb | but make sure it actually does something useful first ... |
| 23:37.18 | seanbright | sure |
| 23:37.30 | seanbright | dude... it allocates memory |
| 23:37.33 | seanbright | !! |
| 23:37.33 | seanbright | heh |
| 23:38.21 | russellb | for best results, should at least be tested on an SMP box |
| 23:59.03 | seanbright | damn |
