It also makes sense for symbol -tables, where derived classes will have the same keys (typically method names), -and the OP trees built for method calls can also share memory. The shared -string table behaves roughly like a cache for hash keys. - -But for hashes actually used as associative arrays - mapping keys to values - -typically the keys are not re-used in other hashes. For example, "seen" hashes -are keyed by object IDs (or addresses), and logically these keys won't repeat -in other hashes. - -Storing these "used just once" keys in the shared string table increases CPU -and RAM use for no gain. For such keys the shared string table behaves as a -cache with a 0% hit rate. Storing all the keys there increases the total size -of the shared string table, as well as increasing the number of times it is -resized as it grows. B<Worse> - in any environment that has "copy on write" -memory for child process (such as a pre-forking server), the memory pages used -for the shared string table rapidly need to be copied as the child process -manipulates hashes. Hence if most of the shared string table is such keys that -are used only in one place, there is no benefit from re-use within the perl -interpreter, but a high cost due to more pages for the OS to copy. - -The perl interpreter now disables shared hash keys for "large" hashes (that are -neither objects nor symbol tables). "Large" is a heuristic - currently the -heuristic is that sharing is disabled when adding a key to a hash triggers -allocation of more storage, and the hash has more than 42 keys. - -This B<might> cause slightly increased memory usage for programs that create -(unblessed) data structures that contain multiple large hashes that share the -same keys.

While most uses within Perl should not care about such -distinctions, this can be useful when serialising or encoding Perl data -structures for export to other languages or data formats where such a -distinction does matter. - -=head2 Support for not sharing all keys in large hash tables. - -This release includes support to build Perl so that it does not share all keys -in hash tables as has been historically the case since Perl v5.6. The shared -key behavior was added to Perl originally to support having many objects with -the same keys without having to store each key many times. For objects that -might be created hundreds or thousands of times this key sharing behavior can -result in using significantly less memory. However, key sharing comes at the -cost of having to maintain an internal "master hash table" (PL_str_tab), and -having to do two store operations per key stored in a hash table. It also can -result in surprising consequences with programs that fork, causing the master -hash table to be COWed (copy on write) into the memory space for each forked -process which can, in worst case, greatly increase the memory utilization of -such scripts. - -The new behavior is an attempt to have our cake and eat it too. Small hash -tables will continue to share keys, but once the hash table is used to store -more than a certain number of keys (currently 64) it will not share the new -keys that are added. This should benefit scripts that build large hash tables, -especially those that do so in forked sub-processes. The unshared mode is -triggered when the hash table is resized which is non-deterministic and depends -on the underlying hash function that perl has been built with and the seed used -by the current process so the exact circumstances when this new mode will be -enabled for a given hash will vary between different invocations of a script. - -We are uncertain of the exact effects of this new mode and are keen to get -field reports about the consequences of enabling it. We know that in many -cases not sharing keys speeds up scripts in general, and may result in a -reduction in memory consumption. Code that builds large hashes where the keys -are stored in only one hash, for instance where the keys are message digests, -will likely benefit from this change by being faster and using less memory. -However, there are also circumstances where not sharing keys can significantly -increase memory consumption, such as where large numbers of keys are stored in -multiple hash tables at once. We have data to suggest that not sharing keys -will reduce COW churn and overall memory consumption in scripts that fork and -construct large hash tables, however such scripts may also encounter a modest -speed penalty. Overall, the consequences of not sharing keys will vary -depending on workload. However, we believe that broadly speaking enabling this -feature will be beneficial for most of our users. We would like to get data -from the field to validate our assumptions. - -We are not enabling the new mode by default in this release as we want to -gather more data and obtain feedback from the field about how it affects -people's scripts, but our intention is to ship the next release of Perl, -version 5.38, with some form of this functionality enabled.

Hashes are still always of type C<SVt_PVHV>, -hash bodies are still allocated from arenas, and the address of the hash -doesn't change, because the address is the pointer to the head structure, which -never moves. - -Internally, a second arena (the arena with index 1) is used to allocate larger -bodies with space for C<struct xpvhv_aux>, the body "upgraded", and the "head" -structure updated to reflect this (much the same way that the bodies of scalars -are upgraded). We already re-purpose arenas - arena with index 0 is used for -C<HE *>s. - -None of this affects documented public XS interfaces. The only code changes are -in F<hv.c> and F<sv.c>.

The following people are known to have -contributed the improvements that became Perl 5.35.9: - -Branislav Zahradník, Christopher Yeleighton, Dagfinn Ilmari Mannsåker, -Dave Cross, David Cantrell, Hugo van der Sanden, James E Keenan, James -Raspass, Karl Williamson, Leon Timmermans, Max Maischein, Michiel Beijen, -Nicholas Clark, Nicolas R., Paul Evans, Renee Baecker, Ricardo Signes, -Sergey Zhmylove, TAKAI Kousuke, Tomasz Konojacki, Tony Cook, Yves Orton. - -The list above is almost certainly incomplete as it is automatically -generated from version control history. In particular, it does not include -the names of the (very much appreciated) contributors who reported issues to -the Perl bug tracker. - -Many of the changes included in this version originated in the CPAN modules -included in Perl's core.

There may also be information at -L<http://www.perl.org/>, the Perl Home Page. - -If you believe you have an unreported bug, please open an issue at -L<https://github.com/Perl/perl5/issues>.
