# Bug Report ## Problem ### What is expected to happen? When calling `FileWriter.write()` (with `create:true` flag) on same file concurrently leads to only one content (maybe the latest being written ?) to be stored into the file ultimately. ### What does actually happen? When calling `FileWriter.write()` (with `create:true` flag) on same file concurrently leads to both content being merged into the same file. ## Information I created a gist file allowing to test and reproduce the issue : https://gist.github.com/fcamblor/9d2552460766a2fe1e203fd45ddae449 The purpose is to concurrently call `FileWriter.write(file, "a")` and `FileWriter.write(file, "b")` then read `file`'s content and check if its content's length is `1` (as expected). If length is `2` (`ab` or `ba`) then it means that concurrent writes have been merged into the same file, which is unexpected. When executing the snippet on Android, I always met the expectation. When executing the snippet on iOS, the expectation is not met quickly (either on 1st, 2nd or 3rd attempt in most of the cases). ### Command or Code See this gist : https://gist.github.com/fcamblor/9d2552460766a2fe1e203fd45ddae449 ### Environment, Platform, Device iPhone 11 Emulator running on iOS 13.2.2 and AppleWebKit/605.1.15 ### Version information `[email protected]` ```> cordova platforms Installed platforms: android 8.1.0 browser 6.0.0 ios 5.1.1 ``` ```> cordova plugins cordova-android-firebase-gradle-release 4.0.0 "cordova-android-firebase-gradle-release" cordova-background-geolocation 3.2.2 "BackgroundGeolocation" cordova-plugin-androidx 2.0.0 "cordova-plugin-androidx" cordova-plugin-androidx-adapter 1.1.1 "cordova-plugin-androidx-adapter" cordova-plugin-background-fetch 5.6.0 "CDVBackgroundFetch" cordova-plugin-cocoalumberjack 0.0.4 "CocoaLumberjack" cordova-plugin-device 2.0.3 "Device" cordova-plugin-dialogs 2.0.2 "Notification" cordova-plugin-exitapp-ios 1.0.0 "ExitApp" cordova-plugin-file 6.0.2 "File" cordova-plugin-file-opener2 2.2.1 "File Opener2" cordova-plugin-file-transfer 1.7.1 "File Transfer" cordova-plugin-firebasex 11.0.3-cli "Google Firebase Plugin" cordova-plugin-geolocation 4.0.2 "Geolocation" cordova-plugin-inappbrowser 3.1.0 "InAppBrowser" cordova-plugin-ionic-webview 4.1.3 "cordova-plugin-ionic-webview" cordova-plugin-network-information 2.0.2 "Network Information" cordova-plugin-request-location-accuracy 2.3.0 "Request Location Accuracy" cordova-plugin-splashscreen 5.0.3 "Splashscreen" cordova-plugin-statusbar 2.4.3 "StatusBar" cordova-plugin-whitelist 1.3.4 "Whitelist" cordova.plugins.diagnostic 6.0.2 "Diagnostic" phonegap-plugin-barcodescanner 8.1.0 "BarcodeScanner"``` ## Checklist - [X] I searched for existing GitHub issues - [ ] I updated all Cordova tooling to most recent version I tried to update `[email protected]` to `[email protected]` but was not able to make all my plugins work with this version. I should have tried to reproduce the error on a dedicated sample with only the file plugin installed on it, but I admit I didn't had the time to (yet). - [X] I included all the necessary information above ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
