python - catch the exception of a subprocess called by another function -

-

I want to automate a script execution on a subprocess, so I use subprocess lib I am doing thread and schedule lib to schedule it to be created.

I would like to verify that the script executed remotely is working without issues when I give script 1 (error) or when script_file is absent Whoever was trying does not print any error (and if I am not mistaken, by adding exception casing, kills subprocess and its work)

import import import Upprosas Import Multiprocessing Import import schedule import time Functools class MyClass: def catch_exceptions Job_func): @ functools.wraps (job_func) def wrapper (* args, ** kwargs): try: excluding job_func (* args, ** kwargs): Import Traceback Print ("Error") Print (traceback.format_exc ()) Return Cover @catch_exceptions def run (auto, user, host, command): subprocesses. Def (defined by user, host, script_path): schedule.every 0.01) .minutes.do (self.run, user, host, script_path)

All tips are welcome, we do not have INP wrapper target, but there is also a good solution to verify the execution of the defined method.

Use subprocess. POPIN () 

  Run cmd = popon (sCmd, shell = true, stdout = PIPE, stderr = PIPE) in RunCmd.stdout for sLine: print (sLine.decode ( )) Stdout.flush () in aLog.append (sLine.decode ()) for RunCmd.stderr in sLine: print (sLine.decode ()) stderr.flush () aErrorLog append (sLine.decode ()) RunCmd. Wait () RunCmd.returncode == 0: Run RunCmd.wait () else: Run RunCmd.returncode

RunCmd.wait () Wait for the process to finish, and the process The code will return (for succuss or failure) also prints the output on realtime.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
