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: 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
`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.
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 6219c015d8 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.
While underlying writer is Allocating writer buffer can grow in
vtable.drain call. We should not hold pointer to the buffer before that
call and use it after.
This remembers positions instead of holding reference.
don't forget to save the list. this allows a
`testing.checkAllAllocationFailures()` test to pass in one of my
projects which newly failed since #24329 was merged.
Rather than having the endian-suffixed functions be the preferred ones
the unsuffixed ones are the preferred ones and the tricky functions get
a special suffix.
Makes packed structs read and written the same as integers.
