QStaticByteArrayMatcher: fix searching in 2+GiB haystacks
Add a test (same techniques as for the 4+GiB check in
tst_qcryptographichash).
Takes ~1s to build the 4GiB test data here, and skips
when RAM is too low:
$ qtbase/tests/auto/corelib/text/qbytearraymatcher/tst_qbytearraymatcher haystacksWithMoreThan4GiBWork
[...]
QDEBUG : tst_QByteArrayMatcher::haystacksWithMoreThan4GiBWork() created dataset in 891 ms
[...]
$ (ulimit -v 2000000; qtbase/tests/auto/corelib/text/qbytearraymatcher/tst_qbytearraymatcher haystacksWithMoreThan4GiBWork)
********* Start testing of tst_QByteArrayMatcher *********
[...]
SKIP : tst_QByteArrayMatcher::haystacksWithMoreThan4GiBWork() Could not allocate 4GiB plus a couple hundred bytes of RAM.
Loc: [/home/marc/Qt/qt5/qtbase/tests/auto/corelib/text/qbytearraymatcher/tst_qbytearraymatcher.cpp(242)]
[...]
Found during 6.3 API review.
[ChangeLog][QtCore][QStaticByteArrayMatcher] Fixed searching in
strings with size > 2GiB (on 64-bit platforms).
Fixes: QTBUG-100118
Pick-to: 6.3
