- fastpath for UnicodeSet.add(new last range)
- fewer UnicodeSet memory allocations:
initial internal list array, exponential array growth,
allocate strings list/set only when first one is added
- faster CodePointTrie.getRange(): fewer calls to filter function
- revert UnicodeSet(intprop=value) from trie ranges to range starts + lookup
- cache per-int-prop range starts: fewer lookups
This resolves the immediate problem of brittle memory management
in the error handling code.
An obvious future improvement would be to replace the old C style
"plain struct with pointers" VariantListEntry, AttributeListEntry
and ExtensionListEntry with contemporary C++ style containers that
take care of ownership and memory management.
The shared templated helper class MemoryPool can be used to replace the
local helper class CodePointMatcherWarehouse, reducing the amount of
specialized code needed.
This eliminates the need for a scratch buffer in Locale::forLanguageTag()
and also the need for counting bytes required in uloc_forLanguageTag(),
something that ByteSink will now handle correctly.
Instead of _appendLDMLExtensionAsKeywords() requiring to receive a pre-
allocated buffer of sufficient size to store all the temporary strings
it needs to store, have it use a MemoryPool<CharString> to allocate
storage space as needed.
Storing strings as individual CharString objects, instead of as NUL
delimited substrings in a contiguous memory area, also eliminates the
need for keeping track of string boundaries and NUL terminators.
By moving the required call to uhash_close() into the destructor of
LocExtKeyData and using CharString instead of raw chunks of bytes
allocated with uprv_malloc(), it becomes easier to guarantee that
memory handling is correct, without leaks or overflows.
With the need for custom deleter functions removed, the code doesn't use
any of the additional functionality provided by UVector, it just needs a
simple way to keep track of allocated objects to delete them after it's
done using them, which MemoryPool does in a simpler and typesafe way.
CalendarDataSink doesn't use any of the additional functionality
provided by UVector, it just needs a simple way to keep track of
allocated objects to delete them after it's done using them.
The shared templated helper class MemoryPool is a drop-in replacement
for the local helper class CharStringPool, with a simpler implementation
and an interface that allows parameters to be passed to the constructor.
This will be used first to replace existing locally defined memory
management helper classes such as CharStringPool (uloc_tag.cpp) and
CodePointMatcherWarehouse (numparse_affixes.h), then in new code.
This eliminates the need for a scratch buffer in Locale::toLanguageTag()
and also the need for counting bytes required in uloc_toLanguageTag(),
something that ByteSink will now handle correctly and thereby
eliminating the bug where too few bytes required was returned.
Using temporary variables for the two values to be compared here makes
GCC compile the code just like we expect it to. (What it really is that
it otherwise does on some architechtures remains a mystery.)
This will make the tests pass as expected also on IA-32 with GCC.
It'll also make it possible to revert the old workaround for SPARC
introduced by commit 5b0592af79.
