This reverts commit e976b3e041.
There is nothing technically wrong with this commit, but it's adding
complexity to a big refactor (native ES modules #975). Since it's not
necessary and simply a philosophical preference, I will revert for now
and try to bring it back later.
This was introduced because Tokio would swallow panics. This is still
the case, but this panic handler causes more problems than it solves.
It requires people to know how to use debuggers to inspect stacktraces.
TODO:
- Fix Tokio to not swallow errors.
- Be vigilant in the intrim to not introduce broken tests due to this
unfortunate "feature" of tokio.
- Don't crash when .mime file not exist in cache (#1291)
- Process source maps in Rust instead of JS (#1280)
- Use alternate TextEncoder/TextDecoder implementation (#1281)
- Upgrade flatbuffers to 80d148
- Fix memory leaks (#1265, #1275)
- Improves speed and binary size significantly.
- Makes deno_last_exception() output a JSON structure.
- Isolate::execute and Isolate::event_loop now return
structured, mapped JSError objects on errors.
- Removes libdeno functions:
libdeno.setGlobalErrorHandler()
libdeno.setPromiseRejectHandler()
libdeno.setPromiseErrorExaminer()
In collaboration with Ryan Dahl.
`Isolate::from_void_ptr` is renamed to `from_raw_ptr`, to keep
consistency with std libs.
It is changed to `unsafe` function, because it can't guarantee that the
input is valid. This guarantee should be provided by the caller.
Its return type is changed to `&Isolate`, because `&mut Isolate` type
requires that no other aliases co-exist in this period of time, this
does not seem true. So I changed most of the methods to accept shared
reference `&Isolate`. It is easier to reason about the correctness of
`unsafe` blocks. As long as these shared references are in the same
thread, these `unsafe` codes are probably correct.
The main purpose of this PR is to remove the `'static` lifetime bound in
type OpCreator =
fn(state: &Arc<IsolateState>, base: &msg::Base, data: &'static mut [u8])
-> Box<Op>;
The reason is simple: it is plain wrong, the `data` is actually not `'static`. It is created when the message is sent from C side, and will be recycled when the message is responded. It violates the definition of `'static` lifetime.
If someone save this pointer somewhere else, and reuse it later again, uninitialized memory could be accessed. This kind of memory unsafety does not happen yet because the logic is carefully organized in this project. Lifetime constraints are maintained by code convention. It could be more robust if we can express this constraint by Rust's type system.
Basic idea: tie buffer's lifetime to an object's lifetime, a.k.a, RAII. The type `deno_buf` is pretty suitable for this job.
This is the second attempt at this patch. The first version was reverted
in 2ffd78daf9
The problem, I suspect, was that the snapshot was represented as a
source_set, which inserted a node into the dependency tree.
include_bytes does properly insert the snapshot into rustc's depfile but
the use of source_set confused gn. Now the that the deno executable has
the create_deno_snapshot as a direct dependency, changes will be
propagated.
Reverting because this is causing Appveyor to be red. However
I hope we can reintroduce include_bytes! soon in a way that
works on windows. Fixes #1208.
This reverts commits 96c3641fff

Changes since v0.1.12:
- First pass at running subprocesses (#1156)
- Improve flag parsing (#1200)
- Improve fetch() (#1194#1188#1102)
- Support shebang (#1197)
- Update to TypeScript 3.1.6 (#1177)
- Fixes Headers type not available. (#1175)
- Reader/Writer to use Uint8Array not ArrayBufferView (#1171)
- Fixes importing modules starting with 'http'. (#1167)
- build: Use target/ instead of out/ (#1153)
- Support repl multiline input (#1165)
Plus some minor improvements and clean-ups:
* Resolve DENO_BUILD_PATH to an absolute path if necessary.
* Rename DENO_BUILD_PATH to GN_OUT_DIR in places where it is supposed to
be set by the build system (and not a user configuration variable).
* Output Cargo `rerun-if-*-changed` instructions first, so even if the
build itself fails, configuration changes will still trigger a re-run
of build.rs.
* Remove TODOs that are impossible.
* Re-run build.rs when the flatbuffer definition file changes.
- Based on code from @qti3e and @piscisaureus in #724 and #1125
respectively.
- TODO The DENO_BUILD_PATH env var must be supplied and must be an
absolute path, this restriction should be removed in future work.
- Add URLSearchParams (#1049)
- Implement clone for FetchResponse (#1054)
- Use content-type headers when importing from URLs. (#1020)
- Use checkJs option, JavaScript will be type checked and users can
supply JSDoc type annotations that will be enforced by Deno (#1068)
- Add separate http/https cache dirs to DENO_DIR (#971)
