dangers of _exit() - memory leak?

由 谁说我不能喝 提交于 2019-12-01 09:21:13
Sorry to repeat a question that has been posed repeatedly, but i couldn't find a specific mention of memory issues. if a process terminates with _exit(0) or _Exit(0) can its memory block be lost to the OS? Thanks, -nuun For just about any consumer O/S that will not happen. Modern multi-process Operating Systems will release any resources the process may have acquired (memory, locks, open files, etc) when the process shuts down. So I generally feel that memory or resource leaks "don't count" as leaks if I just acquire them at startup (not during runtime possibly repeatedly). However, there are

Are javaws exit codes really broken?

由 有些话、适合烂在心里 提交于 2019-12-01 05:14:07
I was working to automate same java code execution using JNLP and I was surprised to discover that jawaws did not gave me a valid return code. Original execution line was: javaws -wait http://example.com:666/missing.jnlp This did showed an ugly window with "Unable to launch application." message. As you can image I tried to make this not require a GUI and tried: javaws -wait -Xnosplash -import -silent http://example.com:666/missing.jnlp But even if this command fails, it will still return 0 , success. How to solve this? This is Bug ID 6898437 in the Oracle/Sun bug tracker, and is fixed in more

STS launch error - Java was started but returned exit code=13

由 寵の児 提交于 2019-12-01 02:26:52
So I installed STS a while back now onto my Windows 7 64-bit machine, every time I try run STS I get the attached Java exit code=13 error below. I don't have have Eclipse installed into my machine, I mention this because every time I have tried to Google this error code threads about the same issue happening on Eclipse come up. I have also tried checking if Java is installed on my machine which it is. Does anyone know how to resolve this? First you need to check that you are using 64 bit java. Next you need to point to that version of java in your STS.ini file. You can do this by specifying

Exit code when python script has unhandled exception

由 混江龙づ霸主 提交于 2019-12-01 01:00:44
问题 I need a method to run a python script file, and if the script fails with an unhandled exception python should exit with a non-zero exit code. My first try was something like this: import sys if __name__ == '__main__': try: import <unknown script> except: sys.exit(-1) But it breaks a lot of scripts, due to the __main__ guard often used. Any suggestions for how to do this properly? 回答1: Python already does what you're asking: $ python -c "raise RuntimeError()" Traceback (most recent call last)

How to deal with negative numbers that returncode get from subprocess in Python?

由 我怕爱的太早我们不能终老 提交于 2019-12-01 00:47:17
This piece of script in python: cmd = 'installer.exe --install ...' #this works fine, the ... just represent many arguments process = subprocess.Popen(cmd) process.wait() print(process.returncode) This code works fine in my opinion, the problem is the value of .returncode .

The installer.exe return: - Success is 0; - Failure and errors are NEGATIVE numbers I have a specific error that is -307 that installer.exe return. But python when

Get Exitcodes from WindowsForms Application in command window

由 北城余情 提交于 2019-12-01 00:39:27
I'm starting a Windows Forms application from the command promt and I need to get the exit codes that the windows forms application generates. The command promt starts the application and returns immediatly. But the application executes in the background. Is there a way to get the Exit codes? Kind Regards Christian. Fowl The answer is start /wait [Your Command] and then echo %errorlevel% to extract the return value. -- And because I like writing batch files... (it's a problem of mine...) @echo off echo Waiting for program to exit... start /wait %* echo Return code was %errorlevel% Save it

Perl: Capturing correct return value from 'system' command

由 馋奶兔 提交于 2019-11-30 22:25:51
I'm a beginner in Perl. I have a Windows batch script which contains multiple NMake commands. An existing issue with this batch script is that even if the NMake command fails during its execution, ERRORLEVEL doesn't get set properly. So we never know whether the command worked until we parse the log file. I looked into it but couldn't find a solution. I, then thought of converting this batch script to a Perl script assuming that trapping error will be easier but it seems it's not that easy :) Whenever I run my Perl script, the 'system' command always returns 0. I looked at many different links
