gecko-dev/third_party/rust/bumpalo/CHANGELOG.md

2.6.0

Released 2019-08-19.

• Implement Send for Bump.

2.5.0

Released 2019-07-01.

• Add alloc_slice_copy and alloc_slice_clone methods that allocate space for slices and either copy (with bound T: Copy) or clone (with bound T: Clone) the provided slice's data into the newly allocated space.

2.4.3

Released 2019-05-20.

• Fixed a bug where chunks were always deallocated with the default chunk layout, not the layout that the chunk was actually allocated with (i.e. if we started growing largers chunks with larger layouts, we would deallocate those chunks with an incorrect layout).

2.4.2

Released 2019-05-17.

• Added an implementation Default for Bump.
• Made it so that if bump allocation within a chunk overflows, we still try to allocate a new chunk to bump out of for the requested allocation. This can avoid some OOMs in scenarios where the chunk we are currently allocating out of is very near the high end of the address space, and there is still available address space lower down for new chunks.

2.4.1

Released 2019-04-19.

• Added readme metadata to Cargo.toml so it shows up on crates.io

2.4.0

Released 2019-04-19.

• Added support for reallocing in-place when the pointer being realloced is the last allocation made from the bump arena. This should speed up various String, Vec, and format! operations in many cases.

2.3.0

Released 2019-03-26.

• Add the alloc_with method, that (usually) avoids stack-allocating the allocated value and then moving it into the bump arena. This avoids potential stack overflows in release mode when allocating very large objects, and also some memcpy calls. This is similar to the copyless crate. Read the alloc_with doc comments and the original issue proposing this API for more.

2.2.2

Released 2019-03-18.

• Fix a regression from 2.2.1 where chunks were not always aligned to the chunk footer's alignment.

2.2.1

Released 2019-03-18.

• Fix a regression in 2.2.0 where newly allocated bump chunks could fail to have capacity for a large requested bump allocation in some corner cases.

2.2.0

Released 2019-03-15.

• Chunks in an arena now start out small, and double in size as more chunks are requested.

2.1.0

Released 2019-02-12.

• Added the into_bump_slice method on bumpalo::collections::Vec<T>.

2.0.0

Released 2019-02-11.

• Removed the BumpAllocSafe trait.
• Correctly detect overflows from large allocations and panic.

1.2.0

Released 2019-01-15.

• Fixed an overly-aggressive debug_assert! that had false positives.
• Ported to Rust 2018 edition.

1.1.0

Released 2018-11-28.

• Added the collections module, which contains ports of std's collection types that are compatible with backing their storage in Bump arenas.
• Lifted the limits on size and alignment of allocations.

1.0.2

1.0.1

1.0.0
