android - Inserted row missing after application restarts -

-

i using ormlite insertion using code below:

protected void registeruser(edittext fullname, edittext email, edittext mobile, edittext username, edittext password) {         //perform db call insert records                          user user = new user();         user.setfullname(fullname.gettext().tostring());         user.setemail(email.gettext().tostring());         user.setmobile(mobile.gettext().tostring());         user.setusername(username.gettext().tostring());         user.setpassword(password.gettext().tostring());          dbmanager.getinstance().adduser(user);     }

but after restarting application, above record missing , login fails. use following code authenticate , works existing records.

public boolean login(string username, string password) {     boolean validlogin = false;     try {                    querybuilder<user, integer> qb = gethelper().getuserdao().querybuilder();                    qb.where().eq("username", username).and().eq("password", password);                  preparedquery<user> pq = qb.prepare();         user user = gethelper().getuserdao().queryforfirst(pq);             if(user!=null){             validlogin = true;         }                } catch (sqlexception e) {e.printstacktrace();}     return validlogin; }

in helper class, creating table when not available.

tableutils.createtableifnotexists(connectionsource, user.class);

how ormlite handle commit operations? have manually commit? please suggest if missing new android , ormlite.

after more information provided in comments, problem seems auto-commit had been disabled either calling dao.setautocommit(false) or starting transaction never finished or rolled back.

using try/finally pattern following recommended.

try {    dao.setautocommit(false);    ...    ...  } {    dao.setautocommit(true);    dao.commit();  }

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...
