#1976: System.Posix.User.getUserEntryForName: incorrect error for non-existent
user
----------------------------+-----------------------------------------------
Reporter: guest | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.8.3
Component: libraries/unix | Version: 6.8.2
Severity: normal | Resolution:
Keywords: errno | Difficulty: Easy (1 hr)
Testcase: | Architecture: x86_64 (amd64)
Os: Linux |
----------------------------+-----------------------------------------------
Changes (by tac-tics):
* keywords: => errno
Comment:
The reason for this is that getUserEntryForName uses a POSIX function
getpwnam_r for its underlying implementation. In the event the user isn't
found, getpwnam_r doesn't actually mess with errno at all, but instead
relies on its 5th parameter to indicate an error. getUserEntryForName
correctly detects the error, but since neither it nor getpwnam_r sets
errno, the text string it displays is Success instead of something more
appropriate.
