Also affects Fedora. +++ This bug was initially created as a clone of Bug #250077 +++ Description of problem: When using du against a directory target that contains, whithin its tree, non-accessible directories, du will not report the size of these. Since stat can get the size, du should do it as well. Moreover, in the code it seems that this was the intention, but a code bug has prevented this tool to report the size of these directories: -- } else if ((sp->fts_child = fts_build(sp, BREAD)) == NULL) { if (ISSET(FTS_STOP)) return (NULL); /* If fts_build's call to fts_safe_changedir failed because it was not able to fchdir into a subdirectory, tell the caller. */ because it was not able to fchdir into a subdirectory, tell the caller. */ if (p->fts_errno) - p->fts_info = FTS_ERR; + if (p->fts_info != FTS_DNR) + p->fts_info = FTS_ERR; /* FIXME: see if this should be in an else block */ LEAVE_DIR (sp, p, "2"); return (p); -- fts_build will return NULL on problems, and if it couldn't opendir() a directory it will set the flag fts_info to FTS_DNR which is an unreadable directory. So not checking if we just reset the flag and avoid counting the size of that directory, however, if we remember it, we can then stat and count its size. Version-Release number of selected component (if applicable): 5.2.1 How reproducible: Always Steps to Reproduce: 1. cd /tmp 2. mkdir -p du_test/unreadable 3. du -a -b du_test 4096 du_test/unreadable 8192 du_test 4. chmod 000 du_test/unreadable 5. du -b -a du_test du: `du_test/unreadable': Permission denied 4096 du_test Actual results: du: `du_test/unreadable': Permission denied 4096 du_test Only the directories that can be readable are counted. Expected results: du test 4 test/dir du: cannot read directory `test/unreachable-dir': Permission denied 12 test Additional info: Patch attached by Bryan Mason <bjmason> Let me know if you need anything else, -- Additional comment from jplans on 2007-07-30 07:47 EST -- Created an attachment (id=160237) Fix report size of unredable subdirectories. -- Additional comment from meyering on 2007-07-30 08:10 EST -- Nice one! Thanks. That's a bug upstream, too.
Built in devel branch as coreutils-6.9-12.fc9, will build for older Fedoras with some other fixes few days later. Closing RAWHIDE.
