The build script wrote the version line to stdout, polluting any pipeline
that captures program output via 'zig build run' or similar. Banners
belong on stderr.
Replaces the linenoise library with isocline for improved REPL
functionality. Updates build scripts and moves completion state from
global variables into the Terminal struct.
config.h already has a hand-added _LIBIDN2_LP_DECLS guarded block at
the end declaring extern strverscmp for the same gnulib-overlay reason.
Move the strchrnul prototype into that block (still #ifdef __APPLE__
since glibc Linux already declares it) so all project-added externs
live in one place, the autoconf-generated section stays untouched, and
the precedent for "how this codebase handles missing glibc extensions"
is one consistent pattern instead of two.
Refresh the build.zig and strchrnul.c comments to point at the
relocated declaration.
No functional change — verified across -target x86_64-macos.{13.0,
14.0,15.4} (lookup.c pattern + the three TUs that include both
<config.h> and <string.h>) plus x86_64-linux-gnu, all under
-Wall -Wextra -Werror.
Move the macOS strchrnul declaration from a side-channel header injected
via -include into vendor/libidn2/config.h itself, gated on __APPLE__.
config.h is the canonical place where libidn2 documents its
HAVE_STRCHRNUL detection — co-locating the platform fallback prototype
there mirrors gnulib's own approach (which declares missing symbols in
its substituted <string.h>) and removes the per-platform build-flag
asymmetry plus the dedicated include path.
The Darwin-only strchrnul.c implementation is unchanged; build.zig now
just adds it on Darwin without touching the lib/ flags array.
Verified that on both `-target x86_64-macos.14.0` (no libc strchrnul)
and `-target x86_64-macos.15.4` (libc has it) a TU mimicking lookup.c
(`#include "config.h"` then call strchrnul) compiles cleanly with no
implicit-declaration error and no redeclaration warning.
libidn2's lib/lookup.c calls strchrnul() unconditionally — a glibc
extension that macOS libc neither defines nor declares. Upstream's
portable build relies on gnulib substituting <string.h> with a
declaration and linking gl/strchrnul.c, but that overlay is not wired
up here. The result was an "implicit function declaration" hard error
on every macOS nightly build.
Add a Darwin-only shim under vendor/libidn2/darwin/ and inject its
prototype into the libidn2 lib/ sources via -include. The shim mirrors
strchrnul's semantics without falling through to rawmemchr (also
glibc-only) since libidn2 only ever searches for '.'.
Links to libidn2 and builds libcurl with it. This makes libcurl work, and by
extension browser, work on international domain names, e.g.
zig build run -- fetch "https://räksmörgås.se/"
With it available, we can use it in our WebAPIs which should also support these
domains, e.g:
testing.expectEqual('xn--rksmrgs-5wao1o.se', new URL('https://räksmörgås.se').hostname);
There is more integration to be done here, but this is a first step.
claude wrote all of the build.zig code.
I don't have a strong opinion about this feature, I just dislike that our WPT
/url/* tests are at 1704 / 9095 and, this is the biggest chunk (although, this
specific commit just does the basic integration and probably won't fix too many
WPT cases directly).
Profiling `zig build --release=fast` after a one-file edit showed the
cost was three parallel exe compiles of the same module — each re-runs
LLVM codegen when anything in `lightpanda_module` changes. All C/C++
deps (v8, sqlite, curl, brotli, nghttp2, boringssl) already cache across
builds and are not the bottleneck.
Default install now builds only the main `lightpanda` exe.
`lightpanda-snapshot-creator` and `legacy_test` move to a new named step
and can be built explicitly via `zig build extras`. CI is unaffected:
nightly.yml already invokes `snapshot_creator` as an explicit step, and
no job consumes the legacy_test artifact.
Measured (release=fast, one source file modified, 36/36 steps):
before: real 3m32s, compile exe lightpanda ~3m, others ~2m each
after: real 2m43s, only compile exe lightpanda
Also tried and rejected:
- self-hosted Zig backend for Debug: fatal linker error, unhandled
relocation type R_X86_64_PC64 in V8 objects.
- mold via `mold -run`: ~4s delta, within noise — Zig invokes LLD
as a library, so no external `ld` process exists to intercept.
This adds an app.storage which is a union around configurable storage engine
(currently, only sqlite).
It is _not_ being used anywhere right now. The goal is to get feedback on
the implementation and then move cache to it.
This doesn't expose a generic query API. The goal is that the storage will
expose high level methods, e.g. `cacheGet(req: CacheGetRequest)` and every
storage engine will translate the `storage.CacheGetRequest` as needed.
A thin wrapper around the Sqlite C api is included, e.g. exec(SQL, .{args}) a
`rows` and `row` fetcher. A connection pool is included. By default, an
in-memory DB is currently created. And a `migrations` table with an id of `1`
is created/inserted. I don't imagine needing fancy migratations.
Some WPT tests need to interact with the browser in a way that isn't possible
with web apis. Browsers need to expose a way for tests to do this and then use
the testdriver-vendor.js to hook into these special WPT actions.
This commit sets up the infrastructure for supporting this and includes
the delete_all_cookies functionality needed by various cookie tests (e.g.
/cookies/attributes/attributes-ctl.sub.html).
A new compilation flag, `-Dwpt_extensions`, can be specified. When specified
a `window.webdriver` accessor is defined and a `WebDriver` type is exposed.
Note that, while I only implemented delete_all_cookies for now, I've seen other
tests fail because of missing vendor-specific implementation.
Introduces `lightpanda agent` command that provides a REPL where users
can chat with an AI that uses the browser's tools (goto, markdown, click,
fill, etc.) to browse the web. Uses zenai for multi-provider LLM support
(Anthropic, OpenAI, Gemini) and linenoise v2 for terminal line editing.
Uses libcurl's websocket capabilities to add support for WebSocket.
Depends on https://github.com/lightpanda-io/zig-v8-fork/pull/167
Issue: https://github.com/lightpanda-io/browser/issues/1952
This is a WIP because it currently uses the same connection pool used for all
HTTP requests. It would be pretty easy for a page to starve the pool and block
any progress.
We previously stored the *Transfer inside of the easy's private data. We now
store the *Connection, and a Connection now has a `transport` field which is
a union for `http: *Transfer` or `websocket: *Websocket`.
Removes manual git flags from CI and build scripts.
Versioning is now automatically derived from git and build.zig.zon.
With this PR, we follow https://semver.org/
Logic:
1. Read the version from build.zig.zon
2. If it doesn't have a `.pre` field (i.e. dev/alpha/beta) it will use that
3. Otherwise it will get the info from git: hash and number of commits since last `.0` version
4. Then build the version: `0.3.0-dev.1493+0896edc3`
Note that, since the latest stable version is `0.2.6`.
The convention is to use `0.3.0-dev`, as:
- `0.2.6` < `0.3.0.dev` < `0.3.0`
- Add git_version option to build.zig (similar to git_commit)
- Update version command to output git_version when available
- Falls back to git_commit when not on a tagged release
- CI can pass -Dgit_version=$(git describe --tags --exact-match) for releases
Fixes#1867
This adds a crash handler which reports a crash (if telemetry is enabled). On a
crash, this looks for `curl` (using the PATH env), and forks the process to then
call execve. This relies on a new endpoint to be setup to accept the "report".
Also, we include very little data..I figured just knowing about crashes would
be a good place to start.
A panic handler is provided, which override's Zig default handler and hooks
into the crash handler.
An `assert` function is added and hooks into the crash handler. This is
currently only used in one place (Session.zig) to demonstrate its use. In
addition to reporting a failed assert, the assert aborts execution in
ReleaseFast (as opposed to an undefined behavior with std.debug.assert).
I want to hook this into the v8 global error handler, but only after direct_v8
is merged.
Much of this is inspired by bun's code. They have their own assert (1) and
a [more sophisticated] crashHandler (2).
