- Refactor: Mv fn `utils::asyncify` into mod `utils`
- Improve err msg for task failure in `utils::asyncify`
- Make sure `asyncify` always returns the same annoymous type
that implements `Future` if the `T` is same.
- Rewrite `extract_bin` to avoid `block_in_place`
support cancellation by dropping
- Rm unused dep scopeguard from binstalk-downloader
- Rewrite `extract_tar_based_stream` so that it is cancellable by dropping
- Unbox `extract_future` in `async_extracter::extract_zip`
- Refactor `Download` API: Remove `CancellationFuture` as param
since all futures returned by `Download::and_*` does not call
`block_in_place`, so they can be cancelled by drop instead of using this
cumbersome hack.
- Fix exports from mod `async_tar_visitor`
- Make `signal::{ignore_signals, wait_on_cancellation_signal}` private
- Rm the global variable `CANCELLED` in `wait_on_cancellation_signal`
and rm fn `wait_on_cancellation_signal_inner`
- Optimize `wait_on_cancellation_signal`: Avoid `tokio::select!` on `not(unix)`
- Rm unnecessary `tokio::select!` in `wait_on_cancellation_signal` on unix
Since `unix::wait_on_cancellation_signal_unix` already waits for ctrl + c signal.
- Optimize `extract_bin`: Send `Bytes` to blocking thread for zero-copy
- Optimize `extract_with_blocking_decoder`: Avoid dup monomorphization
- Box fut of `fetch_crate_cratesio` in `PackageInfo::resolve`
- Optimize `extract_zip_entry`: Spawn only one blocking task per fn call
by using a mspc queue for the data to be written to the `outfile`.
This would improve efficiency as using `tokio::fs::File` is expensive:
It spawns a new blocking task, which needs one heap allocation and then
pushed to a mpmc queue, and then wait for it to be done on every loop.
This also fix a race condition where the unix permission is set before
the whole file is written, which might be used by attackers.
- Optimize `extract_zip`: Use one `BytesMut` for entire extraction process
To avoid frequent allocation and deallocation.
- Optimize `extract_zip_entry`: Inc prob of reusing alloc in `BytesMut`
Performs the reserve before sending the buf over mpsc queue to
increase the possibility of reusing the previous allocation.
NOTE: `BytesMut` only reuses the previous allocation if it is the
only one holds the reference to it, which is either on the first
allocation or all the `Bytes` in the mpsc queue has been consumed,
written to the file and dropped.
Since reading from entry would have to wait for external file I/O,
this would give the blocking thread some time to flush `Bytes`
out.
- Disable unused feature fs of dep tokio

* Add new dep async_zip v0.0.9 to binstalk-downloader
with features "gzip", "zstd", "xz", "bzip2", "tokio".
* Refactor: Simplify `async_extracter::extract_*` API
* Refactor: Create newtype wrapper of `ZipError`
so that the zip can be upgraded without affecting API of this crate.
* Enable feature fs of dep tokio in binstalk-downloader
* Rewrite `extract_zip` to use `async_zip::read::stream::ZipFileReader`
which avoids writing the zip file to a temporary file and then read it
back into memory.
* Refactor: Impl new fn `await_on_option` and use it
* Optimize `tokio::select!`: Make them biased and check for cancellation first
to make cancellation takes effect ASAP.
* Rm unused dep zip from binstalk-downloader
