[Ovmsdev] Attention: esp-idf upgrade still breaks configuration

I have raised the following github issue to Espressif:

https://github.com/espressif/esp-idf/issues/2730 <https://github.com/espressif/esp-idf/issues/2730>

Environment
Development Kit: none
Kit version (for WroverKit/PicoKit/DevKitC): none
Module or chip used: ESP32-WROVER 16MB
IDF version (run git describe --tags to find it): v3.2-beta1-208-g0d7f2d77c
Build System: make
Compiler version (run xtensa-esp32-elf-gcc --version to find it): (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0
Operating System: macOS
Power Supply: USB
Problem Description
TLDR: Between May and July 2018 a change was made to esp idf master that is causing corruption on FAT filesystems mounted on SPI flash.

Our project uses a partitions.csv as follows:

# Name,   Type, SubType, Offset,   Size
nvs,      data, nvs,     0x9000,  0x4000
otadata,  data, ota,     0xd000,  0x2000
phy_init, data, phy,     0xf000,  0x1000
factory,  app,  factory, 0x10000,  4M
ota_0,    app,  ota_0,   ,         4M
ota_1,    app,  ota_1,   ,         4M
store,    data, fat,     ,         1M
The 'store' partition is formatted as FAT, as follows:

esp_vfs_fat_mount_config_t m_store_fat;
wl_handle_t m_store_wlh;
memset(&m_store_fat,0,sizeof(esp_vfs_fat_sdmmc_mount_config_t));
m_store_fat.format_if_mount_failed = true;
m_store_fat.max_files = 5;
esp_vfs_fat_spiflash_mount("/store", "store", &m_store_fat, &m_store_wlh);
We have previously used a clone of esp idf master, dated around May 22 2018, without issues. The partition is very reliable.

However, on Jul 6 2018, we updated our clone to use the latest esp idf master at that time. Shortly afterwards, users started to report that their 'store' filesystem contents were corrupted. We rolled back.

We have now tried again (updating on Oct 20 2018 to v3.2-beta1-208-g0d7f2d77c) and immediately had the same issue. Random corruption of FAT filesystem in SPI flash.

Expected Behavior

No corruption of FAT filesystem.

Actual Behavior

Corruption of FAT filesystem.

Steps to reproduce

Create a partition in SPI flash, and mount FAT filesystem
Read and write to files on FAT filesystem
Reboot
Observe random corruption and unmountable filesystem
Code to reproduce this issue

esp_vfs_fat_mount_config_t m_store_fat;
wl_handle_t m_store_wlh;
memset(&m_store_fat,0,sizeof(esp_vfs_fat_sdmmc_mount_config_t));
m_store_fat.format_if_mount_failed = true;
m_store_fat.max_files = 5;
esp_vfs_fat_spiflash_mount("/store", "store", &m_store_fat, &m_store_wlh);
Debug Logs
n/a

Other items if possible
Please advise if you need anything further.

I think the timeline is correct (the issue is in esp idf master some time between May and July 2018), but please let me know if you know differently (or update the github issue with your comments).

Regards, Mark
