Robust FFI with Memory Protection Keys
by Ben Coman 29 Jun '19

29 Jun '19

A problem with FFI is that if a callout segfaults, all of memory including that of the Image is suspect, and execution of the Image terminates. Occasionally I hunt around hoping to find technology to mitigate that problem. Maybe this time in I found something... Memory Protection Keys [1] Perhaps these could ensure Image memory safe when an FFI callout segfaults. IIUC the main problem with protecting Image memory on every FFI callout is the time it would take update the flags on every page of Image memory. Would being able to change the protection of a massive number of pages with one syscall make it feasible to wrap them around FFI callouts? This may be useful at least where the FFI use is more about reuse of existing functionality than about performance. Or at least useful while someone is learning/experimenting with FFI for the first time or while becoming familiar with some external library.

[OpenSmalltalk/opensmalltalk-vm] Tag the minheadless builds with CMake with a suffix instead of a prefix. (#411)
by Ronie Salgado 27 Jun '19

27 Jun '19

I just noticed that the bintray deployment script has the following regex: {"includePattern": "../products/((newspeak|pharo|squeak).*\\.(?:gz|zip|dmg))", "uploadPattern": "$1"} Since I was tagging the minheadless with a cmake-minhdls- prefix, they build artifacts are not matching this regex. I prefer changing the prefix with a -cmake-minhdls suffix instead of messing with a potentially dangerous regex.
