@raitobezarius:matrix.orgraitobezariusbut also21:17:15
@raitobezarius:matrix.orgraitobezariusmaybe if ((level) <= nix::verbosity)21:17:19
@raitobezarius:matrix.orgraitobezariusidk21:17:20
@raitobezarius:matrix.orgraitobezariusmaybe it exec and just lives its best life21:17:26
@jade_:matrix.orgjade_yeah printInfo might not do anything?? but if you fix it by messing with the link args then surely it's not that. i would have to look at it with instruction level step through with a debugger tbh21:17:52
@jade_:matrix.orgjade_but im currently banging rocks together (writing terraform at work to get gerrit for OSS stuff)21:18:12
@raitobezarius:matrix.orgraitobezarius nix::verbosity is just extern Verbosity verbosity tho 21:18:14
@raitobezarius:matrix.orgraitobezariusit's fine21:18:28
@raitobezarius:matrix.orgraitobezarius https://git.lix.systems/lix-project/lix/issues/941 22:01:45
@emilazy:matrix.orgemily is nix_plugin_entry not that? 22:14:26
@emilazy:matrix.orgemily(I am looking at the plugin code for the first time)22:14:30
@raitobezarius:matrix.orgraitobezariusyes22:14:36
@raitobezarius:matrix.orgraitobezariusbut logger doesn't work at that point22:14:46
@raitobezarius:matrix.orgraitobezariusand I don't see what facilities do we have to initialize the logger22:14:52
@raitobezarius:matrix.orgraitobezariusand if we plan to reuse the Lix's logger22:14:58
@raitobezarius:matrix.orgraitobezariusthen it's clearly not accessible22:15:03
@emilazy:matrix.orgemilycould you show me the command used to link the plugin btw?22:15:52
@emilazy:matrix.orgemilyI half suspect Meson. Meson has some weird ideas about macOS22:16:18
@emilazy:matrix.orgemilyin particular22:16:27
@emilazy:matrix.orgemily

This is useful for building modules that will be dlopen()ed and hence may contain undefined symbols that will be provided by the library that is loading it.

22:16:32
@emilazy:matrix.orgemily I rather suspect that linkage of undefined symbols is what is acting weird here and necessitating -flat_namespace 22:16:53
@emilazy:matrix.orgemily(I can try to build the CL myself and poke at it but not tonight)22:17:56
@emilazy:matrix.orgemily nm -m on the compiled plugin would also be very useful 22:21:30
@ginkogruen:matrix.orgginkogruen joined the room.23:33:15

@raitobezarius:matrix.orgraitobezariusgive me a sec00:18:35
@raitobezarius:matrix.orgraitobezariusah darn ssh is not open to macOS00:18:45
@jade_:matrix.orgjade_contemplating how easy it would be to get coarse grained metrics on each of the known eval time sinners02:51:44
@jade_:matrix.orgjade_like, how much time was spent in an eval copying stuff to the store, waiting on ifd builds, etc02:51:57
@llakala:matrix.orgllakala
In reply to @jade_:matrix.org
contemplating how easy it would be to get coarse grained metrics on each of the known eval time sinners

03:13:33
