file not visible in SPIFFS_readdir

[benpicco-tmp]

Hi,
you' ve always been curious about 'interesting' spiffs states, so I've got this one for you: In this dump there is a file called cli.bin.a32 but it does not show up when querying all files like this

void ls(void) {
    spiffs_DIR dir;
    struct spiffs_dirent file;

    SPIFFS_opendir(&spi_fs, 0, &dir);

    while (SPIFFS_readdir(&dir, &file)) {
        printf("\t%d %s\n", file.size, file.name);
    }

    SPIFFS_closedir(&dir);
}

> ls
2016-05-20 10:56:20,956 - INFO #    0 .volaWare
2016-05-20 10:56:20,978 - INFO #    68736 cli.bin

However, after deleting cli.bin…

> rm_all
2016-05-20 10:56:25,434 - INFO #    deleting cli.bin…
> ls
2016-05-20 10:56:37,208 - INFO #    0 .volaWare
2016-05-20 10:56:37,229 - INFO #    4 cli.bin.a32

it shows up!

I have no trouble opening/reading the file at any time.

my config is

    cfg.phys_erase_block = BLOCK_4K;    // 4096
    cfg.log_block_size   = BLOCK_4K;
    cfg.log_page_size    = 128;

hidden_file.spiffs

Thanks, I will have a peek at it as soon as I can (somewhat chaotic right
now).

Cheers / Peter

Thanks for finding this. It was a corner case indeed, but could lead to potentially very weird behaviour. Please retest with the new patch.

Cheers!

Ok to close?
