I am creating a file on linux using open()
mode_t perms = S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH | S_IWOTH;
int i = open(settingsPath.c_str(), O_CREAT | O_RDWR, perms);
As you can see I am specifiying Read/Write permissions for everyone.
But when I inspect the permissions in a terminal it says
-rw-rw-r-- 1 tstadler tstadler 0 Apr 17 10:54 settings.json
Why can't I give everyone write permissions?
Looks like write permissions to everyone are masked by current process' umask.
See man 2 umask

I've configured SQL second gen. instance and App Engine application (Python 2.7) in one project. I've made necessary settings according to that page.
app.yaml
runtime: python27
api_version: 1
threadsafe: true
env_variables:
CLOUDSQL_CONNECTION_NAME: coral-heuristic-215610:us-central1:db-basic-1
CLOUDSQL_USER: root
CLOUDSQL_PASSWORD: xxxxxxxxx
beta_settings:
cloud_sql_instances: coral-heuristic-215610:us-central1:db-basic-1
libraries:
- name: lxml
version: latest
- name: MySQLdb
version: latest
handlers:
- url: /main
script: main.app
Now as I try to connect from the app (inside Cloud Shell), the error:
OperationalError: (2002, 'Can\'t connect to local MySQL server through socket \'/var/run/mysqld/mysqld.sock\' (2 "No such file or directory")')
Direct connection works:
$ gcloud sql connect db-basic-1 --user=root
was successful...

I've authorized IP to connect to the Cloud SQL instance:
Any hints, help?
Google AppEngine Standard provides a unix socket at /cloudsql/[INSTANCE_CONNECTION_NAME] that automatically connects you to your CloudSQL instance. All you need to do is connect to it at that address. For the MySQLDb library, that looks like this:
db = MySQLdb.connect(
unix_socket=cloudsql_unix_socket,
user=CLOUDSQL_USER,
passwd=CLOUDSQL_PASSWORD)
(If you are running AppEngine Flexible, connecting is different and can be found here)
I am modifying the AudioSystem.cpp code which is part of the mediaserver process running in Android Framework. I added few lines of code in order to make it to write a file located in the sdcard of a Nexus 5 phone.
I am using the following code:
int fd = open("/mnt/shell/emulated/0/file.txt", O_RDWR | O_APPEND | O_CREAT, 0666);
if(fd > -1) {
__android_log_print(ANDROID_LOG_DEBUG, "gxp18", "Writing to SDCARD");
write(fd, "1", strlen("1"));
write(fd, "\n", 1);
close(fd);
}
I am always getting fd = -1. I don't have idea why it fails. In the phone FS I can see that only root and sdcard_r can access the folder:
shell#hammerhead:/mnt/shell/emulated $ ll
drwxrwx--x root sdcard_r 1970-07-04 21:05 0
Interestingly the symbolic link to the sdcard is declare as world readable and writable:
shell#hammerhead:/ $ ll
lrwxrwxrwx root root 1970-07-04 21:04 sdcard -> /storage/emulated/legacy
shell#hammerhead:/storage/emulated $ ll
lrwxrwxrwx root root 1970-07-04 21:04 legacy -> /mnt/shell/emulated/0
I am completely lost. why my write in the AudioSystem.cpp always fails?
Thanks in advance ;)
I have used bosh-lite to deploy a single node cloudfoundry in my development environment. After deployment, I run the bosh vms, and it returns the vms list:
+------------------------------------+---------+---------------+--------------+

| uaa_z1/0 | running | medium_z1 | 10.244.0.130 |
+------------------------------------+---------+---------------+--------------+
But when I try to use "cf api https://api.10.244.0.34.xip.io --skip-ssl-validation" to connect the cloudfoundry, it returns an error:
ConnectEx tcp: No connection could be made because the target machine
actively refused it.
The log information is very general (actually this is the exception from CF client which is written in .net), and doesn't provide useful information.
My question is, which VM handles the api command? And, where can I find the detail log in that VM?
api_z1/0 is handling the command. You can get its logs via the BOSH CLI itself: bosh logs api_z1 0 --all.
You probably also need to add the route to your local route table so that traffic to HAProxy container at 10.244.0.24 knows to go through the BOSH-lite VM at 192.168.50.4. Run bin/add-route or bin/add-route.bat from the root of your BOSH-lite repo.
I am trying to upload around 10 GB file from my local machine to S3 (inside a camel route). Although file gets uploaded in around 3-4 minutes, but it also throwing following exception:

Please see my code below and let me know, where I am going wrong:
TransferManager tm = new TransferManager(
S3Client.getS3Client());
// TransferManager processes all transfers asynchronously,
// so this call will return immediately.
Upload upload = tm.upload(
Utils.getProperty(Constants.BUCKET),
getS3Key(file.getName()), file);
try {
upload.waitForCompletion();
logger.info("Upload complete.");
} catch (AmazonClientException amazonClientException) {
logger.warn("Unable to upload file, upload was aborted.");
amazonClientException.printStackTrace();
}
The stacktrace doesn't even have any reference to my code, hence couldn't determine where the issue is.
Any help or pointer would be really appreciated.
Thanks
I'm using these flags:
SHFILEOPSTRUCTW op;
// ..
op.wFunc = FO_DELETE;
op.fFlags = FOF_ALLOWUNDO | FOF_NORECURSION |
FOF_RENAMEONCOLLISION | FOF_WANTNUKEWARNING |
FOF_FILESONLY | FOF_NOCONFIRMATION |
FOF_NO_CONNECTED_ELEMENTS | FOF_SILENT | FOF_NOERRORUI;
And all works ok for files that are not read-only nor system, but when such file is encountered there is a dialog window for user to confirm moving such file to trash. How to disable it ? Must I work around this by first stripping these attributes or is there a setting I do not know of ?
What I need to do is simply to move a file (one by one, I don't need wildcards) to trash. Are there any other api calls that can do this ?
Hidden attribute is not affected by this behavior.
