Closes#29650.
Currently passing `--platform=browser` does two things:
- makes us prefer the `"browser"` key in package json over module and
main
- makes us prefer the `"browser"` export condition
but we may add more things in the future
Fixes https://github.com/denoland/deno/issues/29707.
Not particularly happy with this one, but the only other idea I had was
to just ignore errors about non-existent exports when we build the graph
for a top level install. That might end up being the best solution.
For background, when you do a top level install that includes a jsr
dependency, we fetch the exports for the jsr package and then use those
exports as roots in the module graph (which triggers caching those
files).
To find those exports correctly, we need to know what version will end
up being cached, otherwise we may end up trying to reference exports
that don't exist on the actual package.
Previously, we could just look up the version in the lockfile and that
worked, but it turns out that was depending on the behavior that was
reverted in https://github.com/denoland/deno/pull/29642.

TODO:
- [x] Tests
- [x] Make some changes to `deno_cache_dir` so we can get the paths for
the local http cache
- [x] Right now this leaves the node modules setup cache in an incorrect
state (removes the symlinks, but doesn't update the setup cache)
- [ ] ~~Handle code cache and other sqlite caches?~~
Fixes#27264. Fixes https://github.com/denoland/deno/issues/28161.
Currently the new lockfile version is gated behind an unstable flag
(`--unstable-lockfile-v5`) until the next minor release, where it will
become the default.
The main motivation here is that it improves startup performance when
using the global cache or `--node-modules-dir=auto`.
In a create-next-app project, running an empty file:
```
❯ hyperfine --warmup 25 -N --setup "rm -f deno.lock" "deno run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto -A empty.js" "deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js" "deno run --node-modules-dir=manual -A empty.js" "deno-this-pr run --node-modules-dir=manual -A empty.js"
Benchmark 1: deno run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 247.6 ms ± 1.7 ms [User: 228.7 ms, System: 19.0 ms]
Range (min … max): 245.5 ms … 251.5 ms 12 runs
Benchmark 2: deno-this-pr run --node-modules-dir=auto -A empty.js
Time (mean ± σ): 169.8 ms ± 1.0 ms [User: 152.9 ms, System: 17.9 ms]
Range (min … max): 168.9 ms … 172.5 ms 17 runs
Benchmark 3: deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
Time (mean ± σ): 16.2 ms ± 0.7 ms [User: 12.3 ms, System: 5.7 ms]
Range (min … max): 15.2 ms … 19.2 ms 185 runs
Benchmark 4: deno run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.2 ms ± 0.8 ms [User: 11.6 ms, System: 5.5 ms]
Range (min … max): 14.9 ms … 19.7 ms 187 runs
Benchmark 5: deno-this-pr run --node-modules-dir=manual -A empty.js
Time (mean ± σ): 16.0 ms ± 0.9 ms [User: 12.0 ms, System: 5.5 ms]
Range (min … max): 14.8 ms … 22.3 ms 190 runs
Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
Summary
deno-this-pr run --node-modules-dir=manual -A empty.js ran
1.01 ± 0.08 times faster than deno run --node-modules-dir=manual -A empty.js
1.01 ± 0.07 times faster than deno-this-pr run --node-modules-dir=auto --unstable-lockfile-v5 empty.js
10.64 ± 0.60 times faster than deno-this-pr run --node-modules-dir=auto -A empty.js
15.51 ± 0.88 times faster than deno run --node-modules-dir=auto -A empty.js
```
When using the new lockfile version, this leads to a 15.5x faster
startup time compared to the current deno version.
Install times benefit as well, though to a lesser degree.
`deno install` on a create-next-app project, with everything cached
(just setting up node_modules from scratch):
```
❯ hyperfine --warmup 5 -N --prepare "rm -rf node_modules" --setup "rm -rf deno.lock" "deno i" "deno-this-pr i" "deno-this-pr i --unstable-lockfile-v5"
Benchmark 1: deno i
Time (mean ± σ): 464.4 ms ± 8.8 ms [User: 227.7 ms, System: 217.3 ms]
Range (min … max): 452.6 ms … 478.3 ms 10 runs
Benchmark 2: deno-this-pr i
Time (mean ± σ): 368.8 ms ± 22.0 ms [User: 150.8 ms, System: 198.1 ms]
Range (min … max): 344.8 ms … 397.6 ms 10 runs
Benchmark 3: deno-this-pr i --unstable-lockfile-v5
Time (mean ± σ): 211.9 ms ± 17.1 ms [User: 7.1 ms, System: 177.2 ms]
Range (min … max): 191.3 ms … 233.4 ms 10 runs
Summary
deno-this-pr i --unstable-lockfile-v5 ran
1.74 ± 0.17 times faster than deno-this-pr i
2.19 ± 0.18 times faster than deno i
```
With lockfile v5, a 2.19x faster install time compared to the current
deno.
This adds support for installing `file:` dependencies in a local
package.json.
In order to use these, you must not set `--node-modules-dir=...` when
using a package.json and it should use the default of
`--node-modules-dir=manual`.
Closes https://github.com/denoland/deno/issues/18701
Updates to use rust 1.85. Doesn't move to the 2024 edition, as that's a
fair bit more involved.
A nice side benefit is that the new rustc version seems to lead to a
slight reduction in binary size (at least on mac):
