There are few more things that could be cleaned up related to the coding style and other things, like explicitly specifying the abi style after "extern" (i.e. `extern "C" fn` instead of `extern fn`), but since those are configurable in rustfmt config, I'm not sure whether the config needs to be added or complying with the defaults should be the priority. But this was just

I want to draw boxplot where the geom_points are displayed based on "ERBB2.MUT" subset and they should be displayed in the right box (based both on the "ERBB2.2064" field and "ERBB2_Status"). However, given my command I currently only see "red" points corresponding to "MUT" subset in one straight line corresponding to only "E...

Hello, I've recently setup FTS solr plugin, following http://wiki2.dovecot.org/Plugins/FTS/Solr, and I have this error in logs when I do a body search : Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Warning: mysql: Query failed, retrying: Unknown column 'disableindexer' in 'where clause' Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Error: sql(user at domain.com): User query failed: Unknown column 'disableindexer' in 'where cl...

This used to be a single patch, but I split it into two with the addition of struct Scatterlist. Again a bit new with Rust submissions. I was told by Gary Guo to rebase on top of rust-next, but it seems *very* behind? The first patch does not build on its own due to a dead_code warning. It is hard to not have dead code when one is adding infrastructure to be used by others at a later

This adds very rough support for writing nbdkit plugins in Rust. This is not very idiomatic -- essentially we're handling the direct C calls from nbdkit in Rust. We have to use ‘unsafe’ in a few places because there's no way to tell the Rust code that nbdkit satisfies guarantees (eg. around thread safety, always returning leaked pointers back to the close function, always doing bounds

Same problem exists, thread A can still be within REAL(call_once), but after it ran user code and set the flag to ~0. Roughly, call_once does: __call_once(flag, arg, func) { mutex_lock(mut); if (flag == BEING_INITIALIZED) { wait } else if (flag == NOT_INITIALIZED_AT_ALL) { flag = BEING_INITIALIZED; mutex_unlock(mut); func(arg); // <=== user code callback mutex_lock(mut); atomic_store(&flag, FULLY_INITIALIZED, mo_release); // "releas...

Similar to what I just did for OCaml (this IS an API break, requiring recompilation of any existing Rust plugin), and done because I want to add fast_zero support to both languages as part of my upcoming fast zero series. Figuring out how to get extents working was hard enough that I punted that, still. Eric Blake (2): rust: Implement can_cache rust: Add support for dynamic .thread_model

Still not working, but I took the latest patch and: - rebased it against libnbd 1.0 - fixed it so it handles new args and cbargs The generator now runs without warnings. This patch doesn't handle optargs at all. In C these are converted to non-optional parameter. Rust doesn't (AFAIK) have optional or labelled arguments unfortunately. Rich.

Hi I hope this is going to the right place. I am trying to write a program which uses KernSmooth library to estimate mutual information between two time series at various different lags. At the moment it’s producing negative values, which is supposed to be impossible (something is fishy). I am summing across one row of the matrix to get p(value is in bin x) and summing across the columns to get p(value is in y), and...

I have tested wine-1.1.38 with Oblivion on Gentoo and I found that the sound effects are no more being played. I`m new to wine bugzilla and I don`t know a proper way to report bugs and regressions. Please if someone is able to report this bug or help me find a way to fix it, I will be glad.
