* extend std.Io.Reader.peekDelimiterExclusive test to repeat successful end-of-stream path (fails)
* fix std.Io.Reader.peekDelimiterExclusive to not advance seek position in successful end-of-stream path
When an error response was encountered, such as 404 not found, the body
wasn't discarded, leading to the string "404 not found" being
incorrectly interpreted as the next request's response.
closes#24732
This is theoretically a bugfix as well, since it enforces the correct
limit on the first write after writing the header. This theoretical bug
hasn't been hit in practice though as far as I know.
Writer.sendFileAll() asserts non-zero buffer capacity in the case that
the fallback is hit. It also requires the caller to flush. The buffer
may be bypassed as an optimization but this is not a guarantee.
Also improve the Writer documentation and add an earlier assert on
buffer capacity in sendFileAll().
* std.Io.Reader: fix confused semantics of rebase. Before it was
ambiguous whether it was supposed to be based on end or seek. Now it
is clearly based on seek, with an added assertion for clarity.
* std.crypto.tls.Client: fix panic due to not enough buffer size
available. Also, avoid unnecessary rebasing.
* std.http.Reader: introduce max_head_len to limit HTTP header length.
This prevents crash in underlying reader which may require a minimum
buffer length.
* std.http.Client: choose better buffer sizes for streams and TLS
client. Crucially, the buffer shared by HTTP reader and TLS client
needs to be big enough for all http headers *and* the max TLS record
size. Bump HTTP header size default from 4K to 8K.

I have noticed however that there are still fetch problems
Previously, index out-of-bounds could occur when copying match_length bytes while decoding whatever sequence happened to overflow `dest`. Now, each sequence checks that there is enough room for the full sequence_length (literal_length + match_length) before doing any copying.

As well as the exact byte count, include a human-readable value so it's
clearer what the error is actually telling you. The exact byte count
might not be worth keeping, but I decided I would in case it's useful in
any scenario.
* std.Io.Reader: appendRemaining no longer supports alignment and has
different rules about how exceeding limit. Fixed bug where it would
return success instead of error.StreamTooLong like it was supposed to.
* std.Io.Reader: simplify appendRemaining and appendRemainingUnlimited
to be implemented based on std.Io.Writer.Allocating
* std.Io.Writer: introduce unreachableRebase
* std.Io.Writer: remove minimum_unused_capacity from Allocating. maybe
that flexibility could have been handy, but let's see if anyone
actually needs it. The field is redundant with the superlinear growth
of ArrayList capacity.
* std.Io.Writer: growingRebase also ensures total capacity on the
preserve parameter, making it no longer necessary to do
ensureTotalCapacity at the usage site of decompression streams.
* std.compress.flate.Decompress: fix rebase not taking into account seek
* std.compress.zstd.Decompress: split into "direct" and "indirect" usage
patterns depending on whether a buffer is provided to init, matching
how flate works. Remove some overzealous asserts that prevented buffer
expansion from within rebase implementation.
* std.zig: fix readSourceFileToAlloc returning an overaligned slice
which was difficult to free correctly.
fixes#24608
The previous code assumed that `initFrame` during the `new_frame` state would always result in the `in_frame` state, but that's not always the case. `initFrame` can also result in the `skippable_frame` state, which would lead to access of union field 'in_frame' while field 'skipping_frame' is active.
Now, the switch is re-entered with the updated state so either case is handled appropriately.
Fixes the crashes from https://github.com/ziglang/zig/issues/24817
Previously, the "allow EndOfStream" part of this logic was too permissive. If there are a few dangling bytes at the end of the stream, that should be treated as a bad magic number. The only case where EndOfStream is allowed is when the stream is truly at the end, with exactly zero bytes available.
Validate wildcard certificates as specified in RFC 6125.
In particular, `*.example.com` should match `foo.example.com` but
NOT `bar.foo.example.com` as it previously did.
Newer 32-bit Linux targets like 32-bit RISC-V only use the 64-bit
time ABI, with these syscalls having `time64` as their suffix.
This is a stopgap solution in favor of a full audit of `std.os.linux` to
prepare for #4726.
See also #21440 for prior art.
The generic syscall table has different names for syscalls that take a
timespec64 on 32-bit targets, in that it adds the `_time64` suffix.
Similarly, the `_time32` suffix has been removed.
I'm not sure if the existing logic for determining the proper timespec
struct to use was subtly broken, but it should be a good chance to
finish #4726 - we only have 12 years after all...
As for the changes since 6.11..6.16:
6.11:
- x86_64 gets `uretprobe`, a syscall to speed up returning BPF probes.
- Hexagon gets `clone3`, but don't be fooled: it just returns ENOSYS.
6.13:
- The `*xattr` family of syscalls have been enhanced with new `*xattrat`
versions, similar to the other file-based `at` calls.
6.15:
- Atomically create a detached mount tree and set mount options on it.
Finally, this commit also adds the syscall numbers for OpenRISC and maps
it to the `or1k` cpu.
`limit` in chunkedSendFile applies only to the file, not the entire
chunk. `limit` in sendFileHeader does not include the header.
Additionally adds a comment to clarify what `limit` applies to in
sendFileHeader and fixed a small bug in it (`drain` is able to return
less then `header.len`).
This "get" is useless noise and was copied from FixedBufferWriter.
Since this API has not yet landed in a release, now is a good time
to make the breaking change to fix this.
`Aegis256XGeneric` behaves differently than `Aegis128XGeneric` in that
it currently encrypts associated data instead of just absorbing it. Even
though the end result is the same, there's no point in encrypting and
copying the ad into a buffer that gets overwritten anyway. This fix
makes `Aegis256XGeneric` behave the same as `Aegis128XGeneric`.
According to https://apilevels.com, 88.5% of Android users are on 29+. Older API
levels require libc as of https://github.com/ziglang/zig/pull/24629, which has
confused some users. Seems reasonable to bump the default so most people won't
be confused by this.
This algorithm is non-trivial and makes sense for any data structure
that acts as an array list, so I thought it would make sense as a
method.
I have a real world case for this in a music player application
(deleting queue items).
Adds the method to:
* ArrayList
* ArrayHashMap
* MultiArrayList
This is one way of partially addressing https://github.com/ziglang/zig/issues/24767
- These functions are unused
- These functions are untested
- These functions are broken
+ The same dangling pointer bug from 6219c015d8e8c958d96e5caa5ef0dbab9c414996 exists in `writePreserve`
+ The order of the bytes preserved in relation to the `bytes` being written can differ depending on unused buffer capacity at the time of the call and the drain implementation.
If there ends up being a need for these functions, they can be fixed and added back.
