Release Notes

rust-lang/regex (regex)

v1.10.0

Compare Source

===================
This is a new minor release of regex that adds support for start and end
word boundary assertions. That is, \< and \>. The minimum supported Rust
version has also been raised to 1.65, which was released about one year ago.

The new word boundary assertions are:

• \< or \b{start}: a Unicode start-of-word boundary (\W|\A on the left,
  \w on the right).
• \> or \b{end}: a Unicode end-of-word boundary (\w on the left, \W|\z
  on the right)).
• \b{start-half}: half of a Unicode start-of-word boundary (\W|\A on the
  left).
• \b{end-half}: half of a Unicode end-of-word boundary (\W|\z on the
  right).

The \< and \> are GNU extensions to POSIX regexes. They have been added
to the regex crate because they enjoy somewhat broad support in other regex
engines as well (for example, vim). The \b{start} and \b{end} assertions
are aliases for \< and \>, respectively.

The \b{start-half} and \b{end-half} assertions are not found in any
other regex engine (although regex engines with general look-around support
can certainly express them). They were added principally to support the
implementation of word matching in grep programs, where one generally wants to
be a bit more flexible in what is considered a word boundary.

New features:

• FEATURE #​469:
  Add support for \< and \> word boundary assertions.
• FEATURE(regex-automata) #​1031:
  DFAs now have a start_state method that doesn't use an Input.

Performance improvements:

• PERF #​1051:
  Unicode character class operations have been optimized in regex-syntax.
• PERF #​1090:
  Make patterns containing lots of literal characters use less memory.

Bug fixes:

• BUG #​1046:
  Fix a bug that could result in incorrect match spans when using a Unicode word
  boundary and searching non-ASCII strings.
• BUG(regex-syntax) #​1047:
  Fix panics that can occur in Ast->Hir translation (not reachable from regex
  crate).
• BUG(regex-syntax) #​1088:
  Remove guarantees in the API that connect the u flag with a specific HIR
  representation.

regex-automata breaking change release:

This release includes a regex-automata 0.4.0 breaking change release, which
was necessary in order to support the new word boundary assertions. For
example, the Look enum has new variants and the LookSet type now uses u32
instead of u16 to represent a bitset of look-around assertions. These are
overall very minor changes, and most users of regex-automata should be able
to move to 0.4 from 0.3 without any changes at all.

regex-syntax breaking change release:

This release also includes a regex-syntax 0.8.0 breaking change release,
which, like regex-automata, was necessary in order to support the new word
boundary assertions. This release also includes some changes to the Ast
type to reduce heap usage in some cases. If you are using the Ast type
directly, your code may require some minor modifications. Otherwise, users of
regex-syntax 0.7 should be able to migrate to 0.8 without any code changes.

regex-lite release:

The regex-lite 0.1.1 release contains support for the new word boundary
assertions. There are no breaking changes.

v1.9.6

Compare Source

==================
This is a patch release that fixes a panic that can occur when the default
regex size limit is increased to a large number.

• BUG aa4e4c71:
  Fix a bug where computing the maximum haystack length for the bounded
  backtracker could result underflow and thus provoke a panic later in a search
  due to a broken invariant.

v1.9.5

Compare Source

==================
This is a patch release that hopefully mostly fixes a performance bug that
occurs when sharing a regex across multiple threads.

Issue #​934
explains this in more detail. It is also noted in the crate
documentation.
The bug can appear when sharing a regex across multiple threads simultaneously,
as might be the case when using a regex from a OnceLock, lazy_static or
similar primitive. Usually high contention only results when using many threads
to execute searches on small haystacks.

One can avoid the contention problem entirely through one of two methods.
The first is to use lower level APIs from regex-automata that require passing
state explicitly, such as meta::Regex::search_with.
The second is to clone a regex and send it to other threads explicitly. This
will not use any additional memory usage compared to sharing the regex. The
only downside of this approach is that it may be less convenient, for example,
it won't work with things like OnceLock or lazy_static or once_cell.

With that said, as of this release, the contention performance problems have
been greatly reduced. This was achieved by changing the free-list so that it
was sharded across threads, and that ensuring each sharded mutex occupies a
single cache line to mitigate false sharing. So while contention may still
impact performance in some cases, it should be a lot better now.

Because of the changes to how the free-list works, please report any issues you
find with this release. That not only includes search time regressions but also
significant regressions in memory usage. Reporting improvements is also welcome
as well! If possible, provide a reproduction.

Bug fixes:

• BUG #​934:
  Fix a performance bug where high contention on a single regex led to massive
  slow downs.

v1.9.4

Compare Source

==================
This is a patch release that fixes a bug where RegexSet::is_match(..) could
incorrectly return false (even when RegexSet::matches(..).matched_any()
returns true).

Bug fixes:

• BUG #​1070:
  Fix a bug where a prefilter was incorrectly configured for a RegexSet.

v1.9.3

Compare Source

==================
This is a patch release that fixes a bug where some searches could result in
incorrect match offsets being reported. It is difficult to characterize the
types of regexes susceptible to this bug. They generally involve patterns
that contain no prefix or suffix literals, but have an inner literal along with
a regex prefix that can conditionally match.

Bug fixes:

• BUG #​1060:
  Fix a bug with the reverse inner literal optimization reporting incorrect match
  offsets.

v1.9.2

Compare Source

==================
This is a patch release that fixes another memory usage regression. This
particular regression occurred only when using a RegexSet. In some cases,
much more heap memory (by one or two orders of magnitude) was allocated than in
versions prior to 1.9.0.

Bug fixes:

• BUG #​1059:
  Fix a memory usage regression when using a RegexSet.

v1.9.1

Compare Source

==================
This is a patch release which fixes a memory usage regression. In the regex
1.9 release, one of the internal engines used a more aggressive allocation
strategy than what was done previously. This patch release reverts to the
prior on-demand strategy.

Bug fixes:

• BUG #​1027:
  Change the allocation strategy for the backtracker to be less aggressive.
