By default, iframes and workers no longer loaded. Use `--load-resources iframe`
and `--load-resources worker` to restore the previous behavior. The disabling
makes resource loading more consistent.
To further make things more consistent, Config seems the following changes:
1. remove `--timeout` from `serve` which does nothing but has printed a
deprecation warning for a long time
2. added .deprecated field to CLI config flags which now logs the specified
deprecated warning when used
3. `--log-filter-scopes` is deprecated in favor of `--log-scopes`
4. `--disable_subframes` is deprecated. Iframe loading is disabled by default,
use `--load-resources iframe` to enable iframe loading
5. `--disable_workers` is deprecated. Worker loading is disabled by default,
use `--load-resources worker` to enable worker loading
6. `--enable_external_stylesheets` is deprecated. Stylesheets remain disabled
by default. Use `--load-resources stylesheet` to enable loading external
stylesheets
CLI log parameters now alter the logger behavior on parse. This helps minimze
the window where default log settings are in-play. It also means things like
this work:
```
./lightpanda --log-level fatal --disable_subframes --log-level warn
```
More seriously, there's now an optional `beforeParse` fired once the mode is
known. This is used by mcp to set the default log level to logfmt. Previously
this was done much later and could easily result in a mix of pretty and logfmt
logs.
Built against https://github.com/lightpanda-io/zig-v8-fork/tree/zig-0.16 but
it doesn't require a new v8 build.
Built against https://github.com/lightpanda-io/boringssl-zig/tree/zig-0.16
since the current fork we point to isn't updated.
A global std.Io instance, lp.io. Way easier this way and requires 0 changes to
our libcurl integration / event loop.
Network code uses a new layer that does what Zig 0.15's posix package used to
do. Again, quicker migration that way. But, as long as we have the global IO,
and given the half-baked nature of networking in std.Io 0.16, this just makes
sense. Things can be migrated as needed.
The std.time.* -> std.Io.Timestamp/Clock/Duration resulted in _a lot_ of
changes. ArrayList = .{} -> ArrayList -> .empty also resulted in a lot of
changes, but that's obviously superficial. As is the trimLeft/trimRight ->
trimStart/trimEnd rename.
Locking adopt the `Uncancelable` variants, e.g. mutex.lockUncancelable() to
preserve the error-free signature (and, because cancellation would be something
we'd have to put more thought into).
std.json.ObjectMap is now unmanaged, so the allocator had to be passed along.
However, there's still a deprecated managed variant of MemoryPool, so I switched
to it (we can do a small follow up PR to move to the unmanaged after).
I tried use_llvm = false, but it locks my computer, consuming RAM until MacOS
gives me a popup I've never seen before, begging me to start killing processes.
Agent and the networking stuff saw the most significant changes.
`cli.zig` is now aware of `help` command at all situations and creates it by itself. Instead of using errors, it initializes `Command` union where `help` branch is active.
`lightpanda <subcommand> help`, `lightpanda <subcommand> --help`
now print only the relevant subcommand options plus common options,
instead of the full text.
`lightpanda help <subcommand>` is also supported
(and that's what use internally).
* Options with optional types are introduced to null by default
* Options with boolean types cannot be optional (nullable)
* Options with boolean types are introduced with false by default
* introduce shortcuts for options that can be provided via single dash
* introduce validators; custom parsing logic can be inserted for niche cases
