A spidermonkey File operation (often) causes the output of "ASS #####" followed by a "File operation pclose failed" error now that I've done a make current (last update was 4 weeks ago). The code puts a 0 or 1 into the variable fdFoundFile for later testing. This has worked for months until the make current. Now it fails with the pclose error 4/5 times. CODE: console_log("info","-3-\n"); //Do a check to make sure we can read the file var fd = new File("|[ -f "+myFileName+" ] && echo 1 || echo 0"); console_log("info","-4-\n"); fd.open("read"); console_log("info","-5-\n"); var fdFoundFile = fd.read(1); console_log("info","-6-\n"); fd.close(); console_log("info","-7-\n"); LOG: 2012-06-08 15:52:14.717917 [INFO] Testcall.js:1 -3- 2012-06-08 15:52:14.717917 [INFO] Testcall.js:1 -4- 2012-06-08 15:52:14.717917 [INFO] Testcall.js:1 -5- ASS 30937 2012-06-08 15:52:14.717917 [INFO] Testcall.js:1 -6- 2012-06-08 15:52:14.717917 [ERR] Testcall.js:258 Error: File operation pclose failed The # following "ASS" always changes and keeps on increasing.
