Hi,

In release v5.4 IDF will be switching to new version of VFS API, which will become the recommended one for users to use.
(Further documentation of the API and switch to new API for IDF-provided file-systems are in-progress)

This PR modifies esp_littlefs to use the new version of the API in all releases from v5.4 onwards.

Thank you!

Thank you! later today I'll double check that all the unit tests work, merge, and release!

@haberturdeur what version of v5.4 are you using? I checked out v5.4-beta1 and am hitting many errors pertaining to the new definitions like:

/Users/brianpugh/esp-idf/tools/unit-test-app/components/littlefs/src/esp_littlefs.c:372:8: error: unknown type name 'esp_vfs_dir_ops_t'; did you mean 'esp_vfs_id_t'?
  372 | static esp_vfs_dir_ops_t s_vfs_littlefs_dir = {
      |        ^~~~~~~~~~~~~~~~~
      |        esp_vfs_id_t

Looks like espressif/esp-idf:v5.4-beta might be tagged incorrectly? @haberturdeur 's commits are on espressif/esp-idf:master though.

I was able to checkout harberturdeur:master and run unit tests.

Test Setup

  • ESP32S3 (WROOM-1-N16-R8) as target
  • "flash_test" partition encrypted
  • power supplied via esp-prog
  • no changes to default VFS configuration in sdkconfig

Test Results

  • Multiple test failures (test-20 through test-25, test-31 through test-35)
  • System panic (test-26).

I rebuilt and re-ran the tests on IDF v5.3.1 and joltwallet:master and got the same results, so maybe the problem is something I'm doing wrong. I haven't analyzed the test results at all yet.

Always trying to minimize RAM usage in our application though -- happy to run some dev builds with v5.4-beta when unit tests get sorted out.

It is not tagged incorrectly. I assume, it just didn't make it to that round of testing and therefore that tag. It is in the release/v5.4 branch, so it should be included in the v5.4 release.

I will take a look at those failing tests.

Hi @tlubke-fireboard,

when running the unit tests I encountered two issues:

  • Failing build because of incompatible pointers - fixed here
  • The same issue as you with open_max_files test, which is caused by incorrect assumption in the tests here
    • For each of the stdin, stdout and stderr file descriptors at least one (usually two) other file descriptors needs to be open (see esp_vfs_console component)
    • For correct offset, you could probably parse output of esp_vfs_dump_fds (docs), but that seems a bit hacky

Note: the rest of the failures in your run seem to be caused by the failed open_max_files, which leaves the FS or VFS in somewhat incorrect state, restart fixes it for me.

The code looks good, and I have confirmed that tests are passing. I'll merge and release this as soon as esp-idf v5.4 is released (just in case something changes). I'll keep an eye out on it, but don't hesitate to ping me!
