[PATCH] Review request: 6962637 TEST_BUG: java/io/File/MaxPathLength.java may fail in busy system (original) (raw)

Hi David,

To use dirFile.length() == 0 to replace the disk space measurement as guess the original test tries to prove that there's no extra disk spent when creating empty folders.

Root cause is the test is not reliable when system is busy, if disk space is changed by some other program, test can fail. so the fix is to check file.length() instead of disk space. I can not figure out what the original version of the test was doing with the disk space measurements but I can certainly appreciate that they could be changing dynamically while the test is running. But I don't really understand why dirFile is expected to have a zero length ??? David Regards, Eric
