2011-04-22fs-tests: integck: simplify dirent manipulationArtem Bityutskiy
Teach 'add_dir_entry()' to allocate the file/dir/symlink object for the client. This simplifies client's code. The only place where we do not want to do this is when we are creating a hardling pointing to an existing file. Teach 'remove_dir_entry()' to free the file/dir/symlink object for the client. Similarly, this simplifies client's code. The only place where we do not want to do this is the rename function - when we rename an object we want to only change its direntry, but not the object itself. But the main motivation for this change is not just to clean-up, but to fix another memory leak. In the re-name function we free the 'rename_entry', but we did not free the corresponding object. This patch fixes the situation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: do not forget to free mount_optsArtem Bityutskiy
The test forgets to free the args.mount_opts string on exit - fix this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: iterate for ever in case of power cut testingArtem Bityutskiy
If the test runs in power-cut testing mode, do not exit in case of EROFS error - but instead re-mount and start again. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: refuse R/O file-systemArtem Bityutskiy
Refuse to test the file-system if it is mounted Read-only. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: free all allocated memory on exitArtem Bityutskiy
Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: assume that the parent is present in new_dirArtem Bityutskiy
We always pass non-NULL 'parent' argument to 'new_dir()', so no need to test it for NULL. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: lessen memory consumption even moreArtem Bityutskiy
This patch kills the "name" field from 'struct file_info' where we stored the original file name. We do not really need to keep this name around, becaus it might have long gone and it is not very interesting. Besides, we have several memory leaks where we leak 'file->name' strings, so this is the easiest way to fix those leaks as well. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: lessen memory consumptionArtem Bityutskiy
We do not need to store directory name in the 'struct dir_info' objects, because we already have it in 'struct dir_entry_info'. So we duplicate the names for directories in 'dir->name' and 'dir->entry->name'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: clean up add_dir_entry usageArtem Bityutskiy
Make 'add_dir_entry()' consistent and allocate name for all types, not only for 'd' and 's'. Also, since 'add_dir_entry()' sets the parent - do not do this in the calling functions. This is a clean-up which makes 'add_dir_entry()' more consistent. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: remove symlinks memory leaksArtem Bityutskiy
When we create a symlink we also allocate a symlink_info structure and the target path name. But when we remove a symlink - we do not delete that memory. This patch fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: free raw write informationArtem Bityutskiy
The test leaks memory like hell because it does not free the raw writes information. This patch fixes the leaks. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: introduce free_writes_info helperArtem Bityutskiy
We have duplicated code for freeing write informatio - put it into a helper function. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: fix memory leak in dir_newArtem Bityutskiy
Do not initialize dir->name because add_dir_entry already does this for us, so we leak the memory. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: fix memory lead in dir_removeArtem Bityutskiy
When removing a directory and freeing corresponding 'dir_info' object - do not forget to free directory name as well. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2011-04-22fs-tests: integck: fix placeholders when printingArtem Bityutskiy
There is a lot of code where %u is used for printing off_t variables, which may be actually 64-bit wide. Fix this by using %llu. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: use unsigned int everywhereArtem Bityutskiy

2011-04-22fs-tests: integck: handle write failures in dir_newArtem Bityutskiy
Do not die in 'dir_new()' if it cannot create a new directory and this is not because of ENOSPC. Return NULL for all errors. Note, not all callers are ready to properly handle all errors so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: check deletion errors in rm_minus_rf_dirArtem Bityutskiy
Modify the 'rm_minus_rf_dir()' function to return -1 in case of any errors during deletions. Make 'integck()' handle the errors. Also introduce a 'pcv()' function to print error message if -v command line option was specified. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-22fs-tests: integck: introduce power cut testing argumentsArtem Bityutskiy
Introduce new command line arguments for power cut testing: -p to enable the power cut testing mode and -v to be verbose about the errors. The real functionality is not implemented so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not expect max name length to be 256Artem Bityutskiy
The 'make_name()' function assumes that the maxumum file name length is 256 bytes, which is wrong. This patch fixes this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: implement own version of CHECKArtem Bityutskiy
Remove the final dependency on the common code - the CHECK() macro. Now we are finally independent. The reason we needed this is that we are going to improve integck to handle errors more gracefully, in order to support failure testing better. And this requires changes in the common code, but it is ancient and shared by many tests, and we do not want to touch it. So we better make integck independent and concentrate on integck only. This patch also removes Makefile dependencies. And while on it, remove the broken 'tests' target. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use tests_random_noArtem Bityutskiy
Do not use the shared 'tests_random_no()' function but use our own simple implementation instead. We do not need those rather complex and difficult to understand computations. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use global common variablesArtem Bityutskiy
Do not use the 'tests_file_system_mount_dir' and 'tests_file_system_type' variables because we do not depend on them any longer. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use tests_get_total_spaceArtem Bityutskiy
Do not use the common tests_get_total_space but extend our own get_free_space function and make it return both free and total amount of space. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use tests_remountArtem Bityutskiy
Implement our own version of 'tests_remount()' instead of depending on the common implementation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use tests_fs_is_rootfsArtem Bityutskiy
Do not use the shared 'tests_fs_is_rootfs()' function - introduce 'fsinfo.is_rootfs' flag and utilize it instead. This is another step forward the goal to make integck independent of the common code. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: prefer to check for successArtem Bityutskiy
Many of standard C libraries return 0 on success and -1 on failure. Currently integck mostly checks for failure by comparing with -1, like: CHECK(fsync(fd) != -1) /* Don't die if not failure */ but in some places the check is like CHECK(fsync(fd) == 0) /* Don't die if success */ This patch harmonizes this an makes integck to use the second style which seems to be more logical. Besides, the binary is smaller in this case: [dedekind@eru fs-tests (master)]$ size integrity/integck-old text data bss dec hex filename 44677 1200 37408 83285 14555 integrity/integck [dedekind@eru fs-tests (master)]$ size integrity/integck-new text data bss dec hex filename 44661 1200 37408 83269 14545 integrity/integck Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use space after castArtem Bityutskiy
Since we are kernel people lets use the style we are accustomed to - no space between the cast and the variable: (type)a, not (type) a. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-04-18fs-tests: integck: do not use tests_clear_dirArtem Bityutskiy
Do not use shared 'tests_clear_dir()' function which removes a directory tree recursively, but instead use own implementation. This is because I'm trying to make integck independend on the shared code because I need this to do further improvements. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
