In an assignment like 'a = &b', is looks suspicious if 'a' has a scope
larger than 'b'.

Some comments still talked about bit 'isrealasize', which has been
removed.

A bad actor could fill only a few entries in a table (power of twos in
decreasing order, see tests) and produce a small table with a huge
length. If your program builds a table with external data and iterates
over its length, this behavior could be an issue.
Short strings can be external, too2025-07-15T17:40:27+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-15T17:40:27+00:00urn:sha1:60b6599e8322dd93e3b33c9496ff035a1c45552f
That complicates a little object equality (and therefore table access
for long strings), but the old behavior was somewhat weird. (Short
strings, a concept otherwise absent from the manual, could not be
external.)

Plus some other details. (Option '-Wuninitialized' was removed from
the makefile because it is already enabled by -Wall.)

When compiling with option HARDMEMTESTS, every creation of a new key
in a table forces an emergency GC.
Small optimization in 'luaH_psetshortstr'2024-12-28T18:05:01+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-12-28T18:05:01+00:00urn:sha1:abf8b1cd4a798fada026b4046e9dbc08791963f2
Do not optimize only for table updates (key already present).
Creation of new short keys in new tables can be quite common in
programs that create lots of small tables, for instance with
constructors like {x=e1,y=e2}.
