15688c4331 Revert "fs/fat/fs_fat32.c: Fixes issue when seeking to end of file where we move one too many clusters ahead due to < vs <= logic. This causes us to move past the last cluster in the file." 
This reverts commit 7ffe023766.

This change is reverted because it introduces other problems when seeking around the file.

97b0235d77 s/dirent: Corrects a problem with opendir() noted by Petteri Aimonen in Bitbucket Issue 132: "opendir() fails for FAT filesystem with trailing slash in path": 
I see the following behaviour on NuttX 7.26, where I have SD card mounted on /flash and a directory called "frm" on it:

opendir("/flash")  returns  (DIR *) 0x1000c580
opendir("/flash/") returns (DIR *) 0x1000c5d0
opendir("/flash/frm")  returns (DIR *) 0x1000c620
opendir("/flash/frm/")  returns (DIR *) 0x0

From POSIX specs for opendir(): "A pathname ... that ends with one or more trailing slashes shall be resolved as if a single dot character ( '.' ) were appended to the pathname."

So for mount points, opendir() works correctly, but for FAT32 filesystem it fails to open directory if the path has a trailing slash. I'm not quite sure how to cleanly fix this. Stripping the trailing slash in opendir() would require allocating a separate buffer, while fixing it in the FAT32 code seems somewhat complex due to the short/long filename logic.

It is not a big issue for me, I'm just going to fix it on the application side. But still a small portability and standards compliance issue.

NOTE: You would not see this problem if you call opendir() indirectly in NSH (like 'ls -R /') because NSH contains logic to remove trailing '/' characters from paths.

Pullreq FAT improvements

* NuttX: Add CONFIG_FAT_LFN_ALIAS_HASH to speed up creating long filenames.

    Long filenames on FAT filesystems have associated 8.3 character alias
    short filenames. The traditional form of these is FILENA~1.EXT with
    a running count of the number of similar names. However creating this
    unique count can take several seconds if there are many similarly named
    files in the directory. Enabling FAT_LFN_ALIAS_HASH uses an alternative
    format of FI0123~1.TXT where the four digits are a hash of the original
    filename. This method is similar to what is used by Windows 2000 and
    later.

* NuttX: Add CONFIG_FAT_LFN_ALIAS_TRAILCHARS alternative format for 8.3 filenames.

    Traditional format for long filename 8.3 aliases takes first 6
    characters of long filename. If this option is set to N > 0,
    NuttX will instead take first 6-N and last N characters to form
    the short name. This is useful for filenames like "datafile12.txt"
    where the first characters would always remain the same.

* NuttX: FAT32: Fix file date corruption in fat_truncate().

* NuttX: if SD card wait seems to be a long one, give time for other threads to run.

6a12213fbb fs/spiffs: I have been test with apps/examples/fstest which provides a good exercise but of the FS internals but not of the user interface. I build an SPIFFS aware NSH configuration and found and fixed a number of glaring usability errors: (1) Missing logic to stat the SPIFFS root directory, (2) Confusion in use to two similarly named struct field... caused files to be unexpectedly deleted. (3) Fixed a sempahore deadlock condition. And (5) Fix /procfs/mount. It was unaware of the SPIFFS file system type. 2018-09-28 17:35:25 -06:00

65ef3acf70 fs/spiffs: Still uses some internal error codes that should be replaced with errors from errno.h. For now, I just added a mapping function before any value is returned to the caller: And of these detailed internal errors are simply mapped to -EFTYPE. Most are related to improper internal data structures so -ETYPE is possibly appropriate. Aslo SPIFFs is no longer is EXPERIMENTAL. Many things work but I the code is very immature and many things will not work. 2018-09-27 11:33:09 -06:00
