[racket-users] raco pkg migrate
after I install the newest racket package on my linux servers I always need to run raco pkg migrate to reinstall dependant packages. trouble is I can never figure out the version name of the previous install. Is there a raco pkg migrate command that can just migrate the packages from the latest previously installed version? Ideally I'd like to automate that so when I apt-get upgrade the packages are migrated for me.

Depends on whether you're using /dynamic/ (same process) or /distributed/ (separate process) places. With dynamic places you can (often) just provide the code for the place to execute. For complicated things you may have to use serial-lambda/serialize/deserialize, but often you can simply provide the necessary functions in context. [details] The Racket GUI library has an issue where e.g. launching an 'Open File' dialog will freeze all of Racket until the user closes the dialog. This can cause the server to time out. Since it's all of Racket that's being frozen and not just the current thread it's necessary to put the server code into an entirely different `place`. And invalidating any part of the visible window does the same thing until the window is redrawn.

[racket-users] build error on the package server for a package whose source is a simple URL (not a Git repo)
I'm not sure if what I'm seeing is a bug or whether I'm using the package system incorrectly, but here goes: I just submitted a package to the package server whose source is a simple URL. It's not a Git repo accessible via HTTPS; it's a Fossil repo, with a server running that serves up a plain old tar-and-gzip'd directory. The error message from the build process: pkg: mismatched checksum on package package source: https://example.com/cool-package/tarball/trunk/download.tar.gz expected: "" got: "a5d851da2832c0b43f7530794987da0a080ebe6d" The naive way to read this error message is: OK, I need to specify a checksum. But there's no checksum field in the form on the package server. You can specify a URL and nothing else. After some digging, I found that checksums can be specified in an info.rkt file, but to my mind that shouldn't be necessary. My thinking is: if I just give a simple URL, the package server should just download the thing, make some reasonable guess about the content (in this case, it can be inferred from the media type in the server's response, but barring that, calling the `file` utility will reveal it's a gzip'd tar file, etc.), and we're off to the races.

Ah, this must be a case where different platforms behave differently, because I still see other threads running even with `finder:std-get-file` on Linux.

Re: [racket-users] Moving a function into a different `place?`
Your "only remaining idea" is what I'd recommend for telling another place what function to run (that's how dynamic-place works in the first place). But your [details] sounds worrying. I just tested on my machine and it didn't happen for me, and I don't think it's supposed to happen on other platforms either.

[racket-users] Moving a function into a different `place?`
What is the best way to pass a function into a child `place`? I've got a server function that accepts a dispatch function as one of its arguments and I need to be able to run the server in a separate `place` (in the dynamic-place sense) because it's part of a GUI application. [details] My initial thought was to start the place and then use place-channel-(put/get) to move the run-time argument from the main place over into the child. I immediately realized that doesn't work because functions are not `place-message-allowed?` values. Next I thought about using a parameter, but parameters in a child place are set to their *initial* values, not their run-time values. (Barring a few special cases.) I considered passing a string or symbol list and then eval'ing it in the child place. I immediately rejected this idea and told my brain that it was being bad and it got no cookies. At this point my only remaining idea is to place-channel-(put/get) a module name that can be dynamic-required in the child place in order to get the dispatch function. Is there a better way? [details] The Racket GUI library has an issue where e.g. launching an 'Open File' dialog will freeze all of Racket until the user closes the dialog. This can cause the server to time out.

Re: [racket-users] machine and network outage at Northeastern
Unfortunately, this has had larger impact than we expected, because a number of places linked directly to mirror.racket-lang.org, which normally hosts downloads. That machine will be down until July 2. In particular, this seems to affect the setup-racket GitHub Action and the homebrew formula for Racket. The main download site, download.racket-lang.org, still works as normal, and linking to that site will continue to work.
