I need to save file to library directory to support retry capability, but some users found it not working.

After some research, I got the following information:

  1. It affects about 100+ users per day, about one in ten thousand of DAU.
  2. 96% of them are iOS 13, others are iOS 9, iOS 10, iOS 12(App lowest support version is iOS9).
  3. Once it occurs, later file creations always failed.
  4. App cant save file to sandbox, including library document temp caches directory, using API [NSString writeToFile:atomically:encoding:error:],the error it returns is "{"localizedRecoveryOptions":"","localizedDescription":"The operation couldn’t be completed.","domain":"NSCocoaErrorDomain","code":512,"localizedFailureReason":"","userInfo":{"NSUserStringVariant":"Folder"},"localizedRecoverySuggestion":""}", The localizedDescription is in Chinese(because the phone locale is Chinese), but I cant type Chinese in the post.
  5. Users some have remaining iCloud storage space and some not. They all have remaining disk stroage space.
  6. The sandbox is not empty, it contains some other files that App creates, but the files cretaed date earlier than the user last reinstall date, may synchronized by iCloud, but the user charging via power, not PC.
  7. The files in sandbox that already exist(eg: sqlite datebase file) can be edited.
  8. Scanning sandbox directory attribute using api -[NSFileManager attributesOfItemAtPath:error:], directory write permission returns "NSFilePosixPermissions":493(755 in Octal).
  9. After reinstall the App, It can create files again, some users after some time(may one day or longer) it occurs agains, the old files come back, newly created files disappear. and other users no more problems.



So why this happned and how can I fix this problem?

Within 

NSCocoaErrorDomain
, error 512 is 
NSFileWriteUnknownError
, which I’ll admit is not very instructive. In most situations like this the error’s 
userInfo
dictionary contains an 
NSUnderlyingErrorKey
property with more info about the error. Any sign of that here?

If you can engage with one of the users hitting this problem, you should ask them to trigger a sysdiagnose log immediately after seeing it. This captures a copy of their system log, which may contain clues as to what’s triggering the problem.

You can learn more about sysdiagnose logs from our Bug Reporting > Profiles and Logs page.

Thanks for your replay.

For now I didn't see the any NSUnderlyingErrorKey field for the error. I can get NSUserStringVariant field only.

For the sysdiagnose logs, I will try to contact the user can reproduce the problem, and then attach the logs.

HI,

Thanks for your remind, I remove the log。

After search the long log file. I did not see the direct error message in the context of the file creation. So I list the log above my error(The last line of the log is the error log of file creation, It printed by third parrt library CocoaLumberjack ), may it helps.

If you need any other message, remind me.

FYI, I rejected your post that contains a link to the sysdiagnose log. Such logs can contain a wide variety of sensitive info and, while they’re super useful for debugging problems coming in from the field, it’s best not to post them in a public place.

As to what you can do with your sysdiagnose log, you should unpack it and open the 

system_logs.logarchive
in Console app. Then start looking for log entries immediately before the failure. A good way to do this is to have your app log to the system log when it sees this error, so that you can locate the exact point in time where it shows up, and then work back from there.

Most of the stuff in the log you posted is networking related. The only thing file related is:

2020-02-17 16:31:59.474397 +0800 filecoordinationd Claim 772E9D0C-CCFE-4754-A337-52D9D785249A was revoked

AFAIK the API you’re calling isn’t coordinated. Are you doing this coordination yourself using 

NSFileCoordinator
?

Also, earlier you wrote:

App cant save file to sandbox, including library document temp caches directory

It’s not clear from that what directory you’re trying to write to here. Please elaborate.

HI:

I didnt use NSFileCoordinator class directlity. After search the source code, I only see the Google Firebase has the code calls.

Other failled logs between the context not contains the call of NSFileCoordinator. But the call of openudid's clicpboard operations.

My test code write files to below directories:

[NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) firstObject];
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject];
NSTemporaryDirectory();

File name generated by uuid for each directories:

NSString *uuid = [[NSUUID UUID] UUIDString];

And write a small string to these files:

NSString *file = [direcotry stringByAppendingPathComponent:uuid];
NSError *error = nil;
[@"test" writeToFile:file atomically:YES encoding:NSUTF8StringEncoding error:&error];

Then I see the error as the post. It means I cant create file.

But there is my database file exists. I guess it sync by iCloud. and the it can be edited.eg: insert update etc.

or can I upload the logfile. And you can search the keyword PURLogFileManagerDefault to see the error context. may it helps?

Yeah, I got nothing )-: My recommendation is that you open a DTS tech support incident and discuss it with one of DTS’s file system experts.

May I add your wei xin(fang zhi he xie)? my wei xin is rock_homeboy and my dian hua hao ma is 18616309756, Im a RD of ByteDance(Douyin), and I have encountered the same problem as you mentioned above, currently contacting the user so that I can provide disk and system log diagnosis to Apple.


Let me describe the problem:

1.Failed to create file through NSFileManager function

- (BOOL)createFileAtPath:(NSString *)path contents:(nullable NSData *)data attributes:(nullable NSDictionary<nsfileattributekey, id=""> *)attr;


The error information obtained by printing errno and strerror (errno) is as follows:

errorCode = 17, errorDesc = File exists.


The following key file attributes are provided:

{
    NSFileCreationDate = "1970-01-01 00:00:02 +0000";
    NSFilePosixPermissions = 493;
    NSFileSystemNumber = 16777222;
    NSFileType = NSFileTypeDirectory;
}

2.Can't write to file using NSData

- (BOOL)writeToFile:(NSString *)path options:(NSDataWritingOptions)writeOptionsMask error:(NSError **)errorPtr;
error: Error Domain=NSCocoaErrorDomain Code=512 "wei neng cun chu gai wen jian" UserInfo={NSUserStringVariant=Folder}

I'm also experiencing a similar issue. One user (out of thousands) is getting a 512 error – NSFileWriteUnknownError when the iOS app attempts to write a file to the caches directory or the documents directory.
The user is on iOS 13.3, and logging the error shows Error Domain=NSCocoaErrorDomain Code=512 "The file couldn’t be saved." UserInfo={NSUserStringVariant=Folder}

Having the exact same problem.


@logicat Did you ever find a root cause or fix besides deleting & reinstalling your app?


  • Can't create any new files.
  • The error message is "The file couldn't be saved." and there is no underlying error in the NSError instance.
  • errno == 17 after the write failure.
  • The file does not actually exist, nor are there any *.tmp.****** files present in the same parent directory.
  • Affects a very small segment of my user base, but that number is growing.
  • In my case, I only have reports for iOS 13+.
  • Offloading the app *does not* fix the problem
  • Deleting & reinstalling the app fixes the problem, but is obviously undesirable.

We have encountered the same exact issue. We've found that we can save a file to other directories like the documents directory but CANNOT save to the caches directory for a specific user.

We kept getting the 512 as well.

@logicat We are running into exact same issue. I was able to obtain the device from my user with an installed copy of our app, however it's an iPad 2 running iOS 9, so sysdiagnose is unavailable as I believe. Console log shows nothing helpful except my error messages. Doing some investigation, I was able to check that underlying error of a [NSData writeToFile:options:error] call is non-existent. I have Firebase (no idea where it's trying to save the file) and CocoaLumberjack logging (trying to save file at Library/Caches) both failing to save the file. Playing with time profiler here are the results of trying to create a new log file for CocoaLumberjack (if it might be helpfull to someone):

However with all that, I have no clue what causes the issue. Were you able to resolve it?
