9 Nov 2022

Wherein we discuss Yulia Startsev’s most recent change to the proposal for synchronous deferred execution of modules, wherein the read barrier is delimited on property access and does not exist for module lexical bindings. We begin to consider the possibility of programs that are correct in isolation and broken in composition with this feature.

Continuation of R&T/Box discussion (moved from 2021-07-28)
Regarding Node.js relaxing its code contribution guidelines around defense against mutation to intrinsics, at the expense of 10% performance and a considerably higher bar for contributors. We conclude that we might be able to make direct use of intrinsics more ergonomic while addressing the concern of safely discovering original intrinsics.
Continued conversation about naming Realms. We arrive at the idea of pairing a taxonomic name with a behavioral name, like ModuleGlobe (née Compartment), IntrinsicsSystem, SharedUniverse, ProcessMultiverse, &c.

Viability Records and Tuples for Stage 3 with Daniel Ehrenberg and champions of Records and Tuples. MarkM brings a concern regarding -0, which the champions address. A concern remains about the coherence of the language, given that some of the goals of tuples and records as suitable as keys in maps and values in sets might be achievable with other means that preserve amortized constant time comparison.

Upcoming changes to Node Policies due to Import Maps (5min) with Bradley Farias. Node.js will allow an escape hatch in policies that will open up ambient authority to import maps. Module specifiers will be eagerly canonicalized into the domain of fully qualified URL or something else that looks like a path relative URL but must not begin with . or .. path components.

Michael FIG led a naming discussion for the eventual-send proposal. Alex Vincent proposed that instead of having a separate constructor, we could create a maker static function on the Promise object that returns a Promise. Saleh proposed the maker function might use the root “delegate” to disassociate the term from handled vs unhandled promise rejections. We agreed to avoid the term proxy on the grounds that, while we borrow the handler pattern from the proxy constructor, the handler itself is not sufficiently similar to a proxy handler to suggest they’re related. By the end of the discussion, we had loose consensus that these names were consistent and good:

* Promise.delegate(handler) returns a “delegated promise” and is analogous to Proxy.revocable, Array.from, or Object.fromEntries, in that it is a static method of a constructor that returns an object of the same type as the constructor.
* Promise.get(promise, prop), Promise.apply(promise, …), Promise.applyMethod(promise, prop, …) all could be static methods of the Promise and that we’ll consider alternatives.
* No changes to the names “presence” and “remotable”.

https://github.com/tc39/proposal-eventual-send/issues/11#issuecomment-618711001

We reviewed Caridy’s proposal for Realms to the “incubator” scheduled for the 27th. We attempted to isolate and address the two major concerns brought up in discussion with members of the committee previously, regarding layering the DOM atop realms and “consistency with the principles of the web”.

Kris updated the group with progress on the Compartment shim. We are beginning to add support for Compartment modules. We may eventually need to extend Compartments to support inter-linkage with modules not defined with JavaScript text, like WASM.

Recorded from the "SES Strategy" meeting on Jan 24, 2019.

Caja consisted of two main parts: Domado, for securing/virtualizing the browser APIs, and SES, for securing JavaScript. Securing the html4 browser API and ES3 were both horrendously difficult. Changes to JavaScript made securing it easy. Changes to the browser have only made the Domado problem worse. What could be changed about the browser to make Domado-level security easy?

Recorded at the "SES Strategy Meeting" on Jan 24, 2019. See https://github.com/erights/PNLSOWNSF/blob/master/PrivateName.js

Bradley observed that a class decorator can obtain the source of the class, rewrite it, evaluate that, and replace the original class with the result. This means there's no loss of security providing a class decorator with access to the internal PrivateName.

However, the decorator can only do an indirect eval. It cannot access the lexical scope that the class appears in. Thus, a "private" declaration that appears outside the class remains protected.

Recorded from the "Frozen Realms shim collaboration" meeting on Jan 22, 2019. See https://github.com/katelynsills/legacy-todo/blob/master/manifest.json

Unfortunately, we accidentally started recording well after this discussion started.

We discussed how the policy decisions expressing what authority should be provided to packages are expressed, who makes those policy decisions, and what the workflow is to make a new policy decision --- or raise an alarm --- when a new version demands more authority.

Resolution:

From outside an application, express and enforce policy on what authority is provided to an application as a whole. We call this the "aggregate authority", as it is aggregated over all packages that comprise the application.

The https://github.com/katelynsills/legacy-todo/blob/master/manifest.json is an example of an application's internal expression and enforcement of policy about how the authority provided to the application as a whole is to be further subdivided and attenuated among the individual packages that comprise the application.

Example: The outside policy may express that the "fs" module that the application as a whole sees is attenuated to providing access to example/*, whereas the application layers on this a further attenuated to provide a particular package with access only to example/log.txt

Recorded from the "Frozen Realms shim collaboration" meeting on Jan 22, 2019. See https://github.com/agoric/ses

Brian Warner walks us through how to install and use the current SES shim. This version of the SES shim directly supports safe evaluators for evaluating strings, but does not yet support safe module loading. We also discuss various packager alternatives for packaging modules as evaluable strings.
