just learned about this project erjic that does seccomp+bwrap sandboxing https://codeberg.org/prisixia/erjic the interface is really nicely designed and i believe will fit the needs of my build system perfectly

i particularly like the profile file format (json, looked up via static path or cli arg) https://codeberg.org/prisixia/erjic/src/branch/main/DOCUMENTATION.txt it being json is extremely important since that makes it reliably possible to normalize and checksum

as you may have inferred from the little orange bar in the codeberg link preview it is in rust which means i will have to make it an optional dep until gccrs is shocked with a bolt of lightning like frankenstein's monster. but sandboxing is so os-specific that it literally has to be an optional dep in any instance

i am not familiar with any sandboxing tool that has such a complete config interface like this profile file. i just spent the last half hour ranting to the author about how i wish every compiler worked like this and how i had to rewrite the scala compiler to do this at twitter inc

they mentioned they use it for running games which is so great to hear bc that's exactly the kind of end-user application that typical sandboxing mechanisms don't care about whatsoever and which (like compilers) have very strong dependencies upon which files they can access

i have just made up an analogy to summarize why json profiles are so important and i refer to it as "b2b vs b2c" software interfaces

@hipsterelectron b2c is "exploit them as much as possible, never give them their means of independence that binds them to your product" and b2b is "only exploit them a reasonable, marketable amount, because their sales people aren't stupid" right

"b2b" is a tongue-in-cheek name for tool-to-tool communication (e.g. build tool => sandbox configuration). this is why the package metadata format i spent years negotiating with the python community to develop https://pip.pypa.io/en/latest/reference/installation-report/ uses JSON, because JSON is extremely stable as a protocol and can be deterministically checksummed. this is why it's suitable for lockfiles

@alina @hipsterelectron don't forget that b2c also has "don't document anything because nobody will read it anyway" while b2b has "don't document anything otherwise they may not need your support contract" -

@hipsterelectron is there anything of constant size that cannot be deterministically checksummed - ohhh wait there are formats without "canonical" form (minus whitespace) i remember that people still have bad ideas sometimes

when brett cannon (the maintainer of the
packaginglibrary who ensures pypi uses the backdooredMETADATAformat) wrote PEP 751 in collusion with astral (the startup that stole my zip file work without credit and sold to openai), he made sure to erase this work, because PEP 751 is a TOML format (and this is the crux of the distinction i'm making) -

@hipsterelectron and then some use toml instead even though it isn't supposed to be read by someone

@hipsterelectron
speaking of games, it should come with a script that sets up a sandboxed Wine desktop

consider for a moment if being able to determine whether a lockfile has been changed might be useful in any way.

PEP 751 is a useful case study in conflation of b2b and b2c because it describes mutually contradictory goals. first off, i claim a lockfile is not user-facing: it is the output of a process invocation (pip, uv, poetry, etc) and intended to be consumed by another process. brett cannon instead courageously fights for user empowerment and describes the lockfile as something a user is expected to audit by hand (so it's their fault if they didn't read it closely enough and get hacked). this motivates the TOML format.

@hipsterelectron if you're already using a structured data format you might as well destructure it into its dictionary representation for doing the comparison right

@hipsterelectron i also wouldnt want my lockfiles to use the canonical / stripped json version but to be pretty-printed instead, of which the formatting can vary

in fact, the TOML format is appropriate for exactly that b2c case! we use it in pants: https://www.pantsbuild.org/stable/docs/getting-started/initial-configuration users of pants have a
pants.tomlat the repo root for this reason.what about subprojects? so pants is a monorepo build tool, and per-directory BUILD files cover project-specific config. BUILD files are restricted python code, because we need to support loops and other logic. this is one major advantage over autoconf, in which key-value configuration parameters are determined by user-provided shell scripts. this makes autoconf-based builds impossible to introspect or interop with other tooling

pants does maintain the same distinction as autoconf in its separation of "maintainer-defined" vs "packager-defined" configuration. in my automake C projects (see e.g. https://codeberg.org/cosmicexplorer/delulu), you'll see i build the
configurescript myself and track it in the repo, while a packager can invoke my prebuilt script from a tarball or git checkout.correspondingly, the
pants.tomldefines configuration values i control, but the packager can override or extend these values via environment variables or cli args. see https://www.pantsbuild.org/stable/docs/using-pants/key-concepts/options for more
