* QRegularExpression: minor fix to captureIndexForNameGiuseppe D'Angelo2012-03-081-0/+3
| | | | | | | | | | | | Although passing a null pointer to pcre16_get_stringnumber for the compiled pattern should simply make it error out, it's actually an undocumented behaviour, so let's stay safe and add an explicit check. Tests for this codepath are added. Change-Id: Ifd9c87874f6812ba487104ec1a5bbc83c3b16761 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* QRegularExpression: improve JIT memory handlingGiuseppe D'Angelo2012-03-081-12/+84
| | | | | | | | | | | | | | | | | PCRE's JIT uses by default 32K on the pcre_exec caller's stack. This is fine for most situations, but in some cases (esp. patterns with lot of recursion) more memory is required. Therefore, if a match execution fails due to exhausting JIT memory, we let PCRE allocate up to 512KB to be used for the JIT's stack. The pointer to the allocated memory is put in thread local storage (so it can be reused from the same thread, if needed, and automatically goes away when the thread dies).

* QRegularExpression: add optimizations autotestGiuseppe D'Angelo2012-03-071-5/+9
| | | | | | | | | | | | | | | Exporting the counter that controls the optimization of a compiled pattern lets us to forcibly optimize all patterns. Therefore, two tests are now run: one with default optimization values and another one which always optimizes the pattern. The counter itself was renamed with a qt_ prefix and put inside the Qt compilation namespace (thanks to rohanpm for pointing it out).

* QRegularExpression: fix optimizePattern, document the issueGiuseppe D'Angelo2012-03-071-7/+24
| | | | | | | | | | | | | | The studyData pointer is atomically set by the pointer assignment, but another processor running a different thread might see the new studyData value but not the memory it points to. Therefore, the current studyData is returned from optimizePattern and used by that thread. Docs were added to optimizePattern to explain what's going on.

* QRegularExpression: do not use JIT in debug buildsGiuseppe D'Angelo2012-03-061-1/+41
| | | | | | | | | | | | | PCRE's JIT uses self-modifying code extensively, requiring full SMC checks enabled by tools like valgrind, which slow down the execution considerably; not enabling SMC checks lead to crashes. Therefore, JIT is now disabled by default in debug builds of Qt. Its usage (both in debug and release builds) can be controlled by setting the QT_ENABLE_REGEXP_JIT environment variable.
