Im using this code to get file content of commit:
GTBlob *blob = [repo lookUpObjectBySHA:#"d39a07ef51533a32da4bf0474462a71a40dc59e4" objectType:GTObjectTypeBlob error:NULL];
NSLog(#"Blob: %#",[blob content]);
where SHA - some specific commit.
But I always get the latest version of this file. What Im doing wrong ?
I found, that to get file in some past states you need:
get GTTree from GTCommit,
then get GTTreeEntry from GTTree and after that
get GTBlob as GTObject via objectWithTreeEntry:GTTreeEntry

I am new to S3 and need to use it for image storage. I found a half dozen versions of an s2wrapper for cf but it appears that the only one set of for v4 is one modified by Leigh
https://gist.github.com/Leigh-/26993ed79c956c9309a9dfe40f1fce29
Dropped in the com directory and created a "test" page that contains the following code:
s3 = createObject('component','com.S3Wrapper').init(application.s3.AccessKeyId,application.s3.SecretAccessKey);
but got the following error :
So I changed the line 37 from
variables.Sv4Util = createObject('component', 'Sv4').init(arguments.S3AccessKey, arguments.S3SecretAccessKey);
to
variables.Sv4Util = createObject('component', 'Sv4Util').init(arguments.S3AccessKey, arguments.S3SecretAccessKey);
Now I am getting:
I feel like going through Leigh code and start changing things is a bad idea since I have lurked here for year an know Leigh's code is solid.
Does any know if there are any examples on how to use this anywhere? If not what I am doing wrong. If it makes a difference I am using Lucee 5 and not Adobe's CF engine.
UPDATE :
I followed Leigh's directions and the error is now gone. I am addedsome more code to my test page which now looks like this :
<cfscript>
s3 = createObject('component','com.S3v4').init(application.s3.AccessKeyId,application.s3.SecretAccessKey);
bucket = "imgbkt.domain.com";
obj = "fake.ping";
region = "s3-us-west-1"
test = s3.getObject(bucket,obj,region);
writeDump(test);
test2 = s3.getObjectLink(bucket,obj,region);
writeDump(test2);
writeDump(s3);
</cfscript>
Regardless of what I put in for bucket, obj or region I get :
JIC I did go to AWS and get new keys:
Leigh if you are still around or anyone how has used one of the s3Wrappers any suggestions or guidance?
UPDATE #2:
Even after Alex's help I am not able to get this to work. The Link I receive from getObjectLink is not valid and getObject never does download an object. I thought I would try the putObject method
test3 = s3.putObject(bucketName=bucket,regionName=region,keyName="favicon.ico");
writeDump(test3);
to see if there is any additional information, I received this :
I did find this article https://shlomoswidler.com/2009/08/amazon-s3-gotcha-using-virtual-host.html but it is pretty old and since S3 specifically suggests using dots in bucketnames I don't that it is relevant any longer. There is obviously something I am doing wrong but I have spent hours trying to resolve this and I can't seem to figure out what it might be.
I will give you a rundown of what the code does:
getObjectLink returns a HTTP URL for the file fake.ping that is found looking in the bucket imgbkt.domain.com of region s3-us-west-1. This link is temporary and expires after 60 seconds by default.
getObject invokes getObjectLink and immediately requests the URL using HTTP GET. The response is then saved to the directory of the S3v4.cfc with the filename fake.ping by default. Finally the function returns the full path of the downloaded file: E:\wwwDevRoot\taa\fake.ping
To save the file in a different location, you would invoke:
downloadPath = 'E:\';
test = s3.getObject(bucket,obj,region,downloadPath);
writeDump(test);
The HTTP request is synchronous, meaning the file will be downloaded completely when the functions returns the filepath.
If you want to access the actual content of the file, you can do this:
test = s3.getObject(bucket,obj,region);
contentAsString = fileRead(test); // returns the file content as string
// or
contentAsBinary = fileReadBinary(test); // returns the content as binary (byte array)
writeDump(contentAsString);
writeDump(contentAsBinary);
(You might want to stream the content if the file is large since fileRead/fileReadBinary reads the whole file into buffer. Use fileOpen to stream the content.
Does that help you?
I'm working with Adwords API, I already can download reports like: all keywords with impressions, clics, ctr, conversions, etc...
The problem is, I need to show this report on our web tool when the user set the date range.
Now I'm doing this: The user selects Start Date 01/09/2014 End Date 15/09/2014, I call Adwords Api, download CSV, parsing it, and then show the results on the screen, but this way is not optimal and I would like to know how to call the API and get the results "at the moment", getting an XML or JSON without download a file.
Is it possible??
The only way I found was calling CampaignService class.. getting all campaigns, then for each campaign calling AdgroupService for get all Adgroups, then keywords.... It's really impractical.
How can I do it?
Thank you very much.
It appears in recent versions of the libary they created a function (getAsString()) so we can achieve this:
$reportDownloader = new ReportDownloader($session);
$reportDownloadResult = $reportDownloader->downloadReport($reportDefinition);
//Normal way of downloading to file
//$reportDownloadResult->saveToFile($filePath);
//printf("Report with name '%s' was downloaded to '%s'.\n",
// $reportDefinition->getReportName(), $filePath);
//New way by calling getAsString();
$reportAsString = $reportDownloadResult->getAsString();
echo $reportAsString;
Old suggestions about passing null as the $filePath no longer work.
Yes, you can get XML without downloading file. Just set $path to Null when calling ReportUtils::DownloadReport() and it returns you response without saving it to file.
The AdWords API library (as of v201506) allows you to set the download_format to one of CSVFOREXCEL, CSV, TSV, XML, GZIPPED_CSV, or GZIPPED_XML. It unfortunately does not support JSON, even if you ask to download the report data (not as a file).
$reportAsString = $reportDownloadResult->getAsString();
$xml = simplexml_load_string($reportAsString);
in my app, I want to load certain image user picks, make some modification, after that, save a copy in my own file format. Since I want to keep track of user modification, I decided to export my file as a package(bundle).
So, in my document class, there's a NSImage object that holds the image file. In the fileWrapperOfType:error: method, I've setup a NSFileWrapper object, and put the object in it. Here's the code:
NSDictionary *fileWrappers = [self.documentFileWrapper fileWrappers];
if (image != nil) {
NSBitmapImageRep *imageRep = [image bitmapImageRepresentation];
NSData *imageData = [imageRep representationUsingType:NSPNGFileType properties:nil];
NSFileWrapper *imageFileWrapper = [[NSFileWrapper alloc]
initRegularFileWithContents:imageData];
[imageFileWrapper setPreferredFilename:#"image"];
[[self documentFileWrapper] addFileWrapper:imageFileWrapper];
}
return self.documentFileWrapper;
In my project plist file, I have two document types, first is the type of public.image since I need to load images in my app:
The other one is my own document type. To make the file a package, I've checked the bundle checkbox in xcode:
If I simply run this now, the code compains that finding extension from type identifier is deprecated, so, I managed to add an entry in Exported UTIs:
At this moment, everything seems working, except that the outputed folder with mdc extension, is indeed a folder instead of a package, what am I missing here? Thanks in advance!
Finally I solved the problem, the key here is to change Conforms To field to com.apple.package.
In order for a package on OS X to be a pkg, it must have a .pkg extension. I hope it is as simple as having the wrong extension.
Note: Until recently, .pkg files were merely directories. Now, we often see package.pkg packages that are obscured cannot be browsed causually without some tricks like using Pacifist, pkgutil or xar:
pkgutil --extract file.pkg folder/
or
xar -xf file.pkg
I have two versions of my model Model001.xcdatamodel and Model002.xcdatamodel. These two are in the Model.xcdatamodeld bundle.
I also have a Model001to002.xcmappingmodel which is not part of the Model.xcdatamodeld. I checked: both the xcmappingmodel and the xcdatamodeld get copied into the .app bundle.
My managed object context is initialized like this:
NSURL *documentModel = [bundle URLForResource:#"Model"
withExtension:#"momd"]; managedObjectModel = [[NSManagedObjectModel alloc]
initWithContentsOfURL:documentModel]; return managedObjectModel;
I also set these properties on my overridden initWithFileURL: in my UIManagedObject subclass.
NSMutableDictionary *options = [NSMutableDictionary dictionaryWithDictionary:self.persistentStoreOptions];
[options setObject:#YES forKey:NSMigratePersistentStoresAutomaticallyOption];
[options setObject:#YES forKey:NSInferMappingModelAutomaticallyOption];
self.persistentStoreOptions = [options copy];
But when I try to open a documet, I get the following error:
Can't find mapping model for migration
-- UPDATE --
Even if I do a manual migration
[NSMappingModel mappingModelFromBundles:#[[NSBundle mainBundle]]
forSourceModel:sourceObjectModel
destinationModel:self.managedObjectModel];
this returns nil. Although I double checked that the Model001to002.cdm is in the app bundle. It has to be in the app bundle right?
A "gotcha" with mapping models is that you are not allowed to make any changes to the models after you created the mapping. If you do, you will also get this error.
OK, solved the problem by removing all core data files from Xcode, reading them and setting the source and destination of the mapping model again.
Damn you Xcode!
You are not allowed to make any changes to the source/destination model after you have created the mapping models.
If you do make some changes,
mappingModelFromBundles:forSourceModel:destinationModel: will not be able to find the mapping model file
addPersistentStoreWithType:configuration:URL:options:error: with {NSInferMappingModelAutomaticallyOption: #NO} will report an error "Can't find mapping model for migration"
migrateStoreFromURL:type:options:withMappingModel:toDestinationURL:destinationType:destinationOptions:error: will report an error "Mismatch between mapping and source/destination models"
So, just recreate the mapping model and copy every change you made in the old one.
TL;DR
At least as of Xcode 8/9, open the mapping model then from the Editor menu select Refresh data models. Usually it seems you need to restart Xcode. If that doesn't do it you might try re-selecting the destination at the bottom of the model editor.
More Tips
Definitely NEVER change a model after it has been distributed in an app build.
For this example, let's say you have published Data Model 1 (DM1) and are making a migration to DM2. If you set DM2 as the active version then run your app, a migration will run on your persistent store. If you then make another change to DM2, run your app... Boom!
The issue is that your store has already been migrated to "DM2" but the data in the store doesn't fit into the model anymore. And, we can't migrate from DM2 to DM2 again.
It may seem like an obvious solution to go ahead and create DM3. It is
usually a good idea though to minimize the number of models and
migrations while you are developing.
So... now you have a persistent store that has been migrated to a defunct DM2. How do you test the migration again? You could revert your app and generate some data with DM1 but I prefer to use backups
Creating a backup
Before you run your app with DM2 you can copy the existing store (with DM1) to use for later test migrations. On macOS you can easily do this manually. The code below should do the trick as well. Typically you wouldn't want to ship this, rather you could just put it somewhere before your normal CD stack opens, run the app, then stop the app (maybe place a breakpoint just after then end the run via Xcode).
let fm = FileManager.default
let url = // The store URL you would use in ↓
// try coordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: nil, at: url, options: nil)
let dir = url.deleteLastPathComponent().appendingPathComponent("Backup", isDirectory: true).appendingPathComponent("DM1", isDirectory: true)
print("Saving DB backup for DM1")
if !fm.fileExists(atPath: dir.path) {
do {
// Create a directory
try fm.createDirectory(at: dir, withIntermediateDirectories: true, attributes: nil)
let backupURL = dir.appendingPathComponent(url.lastPathComponent)
try fm.copyItem(at: url, to: backupURL)
}
catch {
print("Failed to save DB backup")
}
}
Oops, I need to make another change...
If you run your migration to DM2 then realize you need to make another change, you'll want to re-test your migration from DM1 -> DM2. This is where the backup comes in.
Same way you made the backup, run this code.
let fm = FileManager.default
let url = // The store URL you would use to add the store
let dir = url.deleteLastPathComponent().appendingPathComponent("Backup", isDirectory: true).appendingPathComponent("DM1", isDirectory: true)
let backupURL = dir.appendingPathComponent(url.lastPathComponent)
if fm.fileExists(atPath: backupURL.path) {
do {
fm.removeItem(at: url.path)
try fm.copyItem(at: backupURL, to: url)
}
catch {
print("Failed to restore DB backup")
}
}
You now have a restored DM1 store and have made changes to DM2. If you run the app the migration might succeed but it won't use your custom mapping model.
Remember if you are using a custom mapping, you will still need to use the Refresh Data Models technique before the mapping model will work.
This can happen if your test device's store is from a version of the data model that no longer exists.
For example I had Data Model Version 7, then I made Data Model Version 8. I made a mapping model to go from 7 to 8. Then I ran it on my test device and everything was happy.
Then I made some more changes to 8.
The thing to realize is that in Core Data, every model has a hash identifier that the system creates by taking a checksum of the xcdatamodel file. So if you make even a slight change, even if you didn't create a new version, it sees it as a different version. These versions' identifiers are NSStoreModelVersionHashes (see documentation here).
So in other words, I ended up with:
Data Model 7 (release) - 0plcXXRN7XHKl5CcF+fwriFmUpON3ZtcI/AfK748aWc=
Data Model 8 (beta) - qeN1Ym3TkWN1G6dU9RfX6Kd2ccEvcDVWHpd3LpLgboI=
Data Model 8 (release) - EqtMzvRnVZWkXwBHu4VeVGy8UyoOe+bi67KC79kphlQ=
Instead of making a version 9, and saving the original version 8 in the data model history, I just updated 8, figuring automatic migration could take care of me. Well, it couldn't, and I couldn't make a mapping between the two, because the old (beta) version of 8 was gone.
I did it that way because it was an intermediary internal build (not a release) so it wasn't a big deal, but it did throw me for a loop!
If it wasn't an internal build and I needed to make this work, I could go back to the (beta) commit and pull out that xcdatamodel file for 8 (beta), rename the (release) version to 9, then stick it into the release build and make a mapping model between 8 and 9.
However since it was just an internal beta build, we just erased and reinstalled the app on test devices. We did verify that, when going from 7 (release) to 8 (release), the migration went smoothly.
Removing Coredata files from its path an re - run project is worked for me
I'm trying to write/create a JSON file from a AIR app, I'm trying not so show a 'Save as' dialogue box.
Here's the code I'm using:
var fileDetails:Object = CreativeMakerJSX.getFileDetails();
var fileName:String = String(fileDetails.data.filename);
var path:String = String(fileDetails.data.path);
var f:File = File.userDirectory.resolvePath( path );
var stream:FileStream = new FileStream();
stream.open(f, FileMode.WRITE );
stream.writeUTFBytes( jsonToExport );
stream.close();
The problem I'm having is that I get a 'Error 3013. File or directory in use'. The directory/path is gathered from a Creative Suite Extension I'm building, this path is the same as the FLA being developed in CS that the Extension is being used with.
So I'm not sure if the problem is that there are already files in the directory I'm writing the JSON file to?
Do I need to add a timer in order to close the stream after a slight delay, giving some time to writing the file?
Can you set up some trace() commands? I would need to know what the values of the String variables are, and the f.url.
Can you read from the file that you are trying to write to, or does nothing work?
Where is CreativeMakerJSX.getFileDetails() coming from? Is it giving you data about a file that is in use?
And from Googling around, this seems like it may be a bug. Try setting up a listener for when you are finished, if you have had the file open previously.
I re-wrote how the file was written, no longer running into this issue.
