* QRegularExpression: print a warning if (?J) is used in a patternGiuseppe D'Angelo2013-02-121-0/+32
| | | | | | | | | (?J) inside a pattern string can be used to allow or disallow duplicated capturing group names in the pattern string itself. Although PCRE supports duplicated names, in Qt we don't yet. Change-Id: I21cd0c41273cd7ef42870ced3a0fad6ba7035cbc Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* QRegularExpression: add method for extracting the capturing group namesGiuseppe D'Angelo2013-02-051-0/+81
| | | | | | | | | | | | | | | | It may be useful to know which named capturing groups are defined in an regular expression, and for each of them, what's the corresponding index. This commit adds the needed method to QRegularExpression. Note that extracting the information doesn't happen while holding the mutex in the private -- pcre_fullinfo just reads information from the compiled pattern, so that's thread-safe.

| | | | | | | | | | | | | | | | | | | | This match type doesn't do any match at all; it's only necessary to properly introduce default constructors for QRegularExpressionMatch and QRegularExpressionMatchIterator (since they return the match type that created them).

| | | | | | | | | | | | 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'Angelo2012-03-081-0/+27
| | | | | | | | | | | | | | | | | 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'Angelo2012-03-071-39/+1
| | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | Some minor fixes: obviously, a valid match always come from a valid regular expression, but a valid regular expression can create an invalid match (internal error during matching). Also, testing an invalid iterator should silence the emitted warnings. Change-Id: I585bb99a81e22f108601fd66bf30b56e0229d68b Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
