html - Safari specific scroll bar issue in legacy code -

-

i trying debug issue occurring in safari. on few pages of web application, content larger frame , scroll bar appears on right when scroll bar moves or down content not scroll it. can "scroll" scroll bar content inaccessible though scroll bar mobile.

the issue occurs in "multi-process windows" debug mode option not in "single-process windows" option. scroll bar works fine in firefox, ie, , chrome, not in safari. because there's lot of legacy code, i'm not quite sure actual content , specific html elements relevant. can tell there's iframe element, html element, body element, div element, iframe element html element, body element , divs.

edit matter if of elements within <iframe> have attribute scrolling="no"? see on few of elements within iframe coworker reassures me don't matter.

have tried adding overflow-y: scroll; body css?

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
