runningApplications deprecated in Mavericks, or what? - deprecated

Compiling the same project under OSX 10.8.5 and 10.9, I have found that runningApplications does not work with the same function as mentioned below:
-(void)killProcessesNamed:(NSString*)appName
{
for ( id app in [[NSWorkspace sharedWorkspace] runningApplications] )
{
if ( [appName isEqualToString:[[app executableURL] lastPathComponent]] )
{
[app terminate];
}
}
}
Looking at NSRunningApplication.h I've found this:
- (NSArray *)runningApplications NS_AVAILABLE_MAC(10_6);
I do not know if it is really deprecated, but I get a warnings about multiple ambiguous method found in NSRunningApplication.h and also in NSTask.h both regarding:
- (BOOL)terminate; // in NSRunningApplication.h
- (void)terminate; // in NSTask.h
therefore the warning disappears if I change terminated in forceTerminate:
//[app terminate];
[app forceTerminate];
The problem is that in Mavericks does not want to kill the process/app indicated.
To be more clear, the above warning appears only if the project is under ARC.
thanks

PhpStorm with PHPUnit 8.4 gives exception Uncaught PHPUnit\Runner\Exception class ... could not be found

I tried to use PHPUnit v8. However I was not succeeded with PhpStorm. When I run simple test (class method) in PhpStorm I got the following message:
PHP Fatal error: Uncaught PHPUnit\Runner\Exception: Class 'Mrself\\TreeType\\Tests\\Functional\\BuildingTest' could not be found in '/vagrant/symfony-tree-type/tests/Functional/BuildingTest.php'. in /vagrant/symfony-tree-type/vendor/phpunit/phpunit/src/Runner/StandardTestSuiteLoader.php:65
Yes, I have that class and yes I have psr configured properly:
"autoload": {
"psr-4": {
"Mrself\\TreeType\\": "./src/"
}
},
"autoload-dev": {
"psr-4": {
"Mrself\\TreeType\\Tests\\": "./tests/"
}
}
The proof the I have everything correctly setup is that when I run vendor/bin/phpunit it gives me correct result.
When I run method in PhpStorm I got the following call:
/usr/bin/php /vagrant/symfony-tree-type/vendor/phpunit/phpunit/phpunit --configuration /vagrant/symfony-tree-type/phpunit.xml --filter "/(::testFormCanBeBuild)( .*)?$/" Mrself\\TreeType\\Tests\\Functional\\BuildingTest /vagrant/symfony-tree-type/tests/Functional/BuildingTest.php --teamcity
However if I prepend class namespace with \\ everything works correctly as well. I can not get a clue what's going on. PHPUnit version 7 works as well.
Same thing happened to me. All of the sudden I started getting the following error:
PHP Fatal error: Uncaught PHPUnit\Runner\Exception: Class 'Tests\\Feature\\ExampleTest' could not be found
And after I have read #frank-vue's comment I noticed the same thing and he did: If I run tests on the entire folder it runs normally, but if I run test on a specific class/method I get that error.
I tried earlier version of PHPStorm, downgraded PHP plugin etc... and nothing worked.
In my case, when I checked the stacktrace looks like:
#0 /var/www/vendor/phpunit/phpunit/src/Runner/BaseTestRunner.php(145): PHPUnit\Runner\StandardTestSuiteLoader->load('Tests\\\\Unit\\\\Ex...', '/var/www/tests/...')
#1 /var/www/vendor/phpunit/phpunit/src/Runner/BaseTestRunner.php(105): PHPUnit\Runner\BaseTestRunner->loadSuiteClass('Tests\\\\Unit\\\\Ex...', '/var/www/tests/...')
#2 /var/www/vendor/phpunit/phpunit/src/TextUI/Command.php(177): PHPUnit\Runner\BaseTestRunner->getTest('Tests\\\\Unit\\\\Ex...', '/var/www/tests/...', Array)
#3 /var/www/vendor/phpunit/phpunit/src/TextUI/Command.php(159): PHPUnit\TextUI\Command->run(Array, true)
#4 /var/www/vendor/phpunit/phpunit/phpunit(61): PHPUnit\TextUI\Command::main()
#5 {main}
thrown in /var/www/vendor/phpunit/phpunit/src/Runner/StandardTestSuiteLoader.php on line 69
Notice Tests\\\\Unit\\\\Ex... instead of Tests\\Unit\\Ex....
So in the end I broke the rule and I've modified vendor file, which should be avoided at any cost, but as a temporary solution it solves my problem.
So I added 1 line to the vendor/phpunit/phpunit/src/Runner/BaseTestRunner.php on line 98 (PHPUnit version 8.4.1), which replaces unnecessary '\'s.
if (empty($suiteClassFile) && \is_dir($suiteClassName) && !\is_file($suiteClassName . '.php')) {
/** #var string[] $files */
$files = (new FileIteratorFacade)->getFilesAsArray(
$suiteClassName,
$suffixes
);
$suite = new TestSuite($suiteClassName);
$suite->addTestFiles($files);
return $suite;
}
$suiteClassName = str_replace('\\\\', '\\', $suiteClassName); // THIS IS THE LINE I ADDED
try {
$testClass = $this->loadSuiteClass(
$suiteClassName,
$suiteClassFile
);
} catch (Exception $e) {
$this->runFailed($e->getMessage());
return null;
}

posix_fallocate() failed: Operation not permitted while opening .realm file

I get the below error when i try to open and download .realm file in /tmp directory of serverless framework.
{"errorType":"Runtime.UnhandledPromiseRejection","errorMessage":"Error: posix_fallocate() failed: Operation not permitted" }
Below is the code:
let realm = new Realm({path: '/tmp/custom.realm', schema: [schema1, schema2]});
realm.write(() => {
console.log('completed==');
});
EDIT: this might soon be finally fixed in Realm-Core: see issue 4957.
In case you'll run into this problem elsewhere, here's a workaround.
This caused by AWS Lambda not supporting the fallocate and fallocate64 system calls. Instead of returning the correct error code in this case, which would be EINVAL for not supported on this file system, Amazon has blocked the system call so that it returns EPERM. Realm-Core has code that handles EINVAL return value correctly but will be bewildered by the unexpected EPERM returned from the system call.
The solution is to add a small shared library as a layer to the lambda: compile the following C file on Linux machine or inside lambda-ci Docker image:
#include <errno.h>
#include <fcntl.h>
int posix_fallocate(int __fd, off_t __offset, off_t __len) {
return EINVAL;
}
int posix_fallocate64(int __fd, off_t __offset, off_t __len) {
return EINVAL;
}
Now, compile this to a shared object with something like
gcc -shared fix.c -o fix.so
Then add it to a root of a ZIP file:
zip layer.zip fix.so
Create a new lambda layer from this zip
Add the lambda layer to your lambda function
Finally make the shared object be loaded by configuring the environment value LD_PRELOAD with value /opt/fix.so to your Lambda.
Enjoy.

QBS: Explicitly setting qbs.profiles inside Products causing build to fail

My use-case is this:
I have a static library which I want to be available for some profiles (e.g. "gcc", "arm-gcc", "mips-gcc").
I also have an application which links to this library, but this applications should only build using a specific profile (e.g. "arm-gcc").
For this I am modifying the app-and-lib QBS example.
The lib.qbs file:
import qbs 1.0
Product {
qbs.profiles: ["gcc", "arm-gcc", "mips-gcc"] //I added only this line
type: "staticlibrary"
name: "mylib"
files: [
"lib.cpp",
"lib.h",
]
Depends { name: 'cpp' }
cpp.defines: ['CRUCIAL_DEFINE']
Export {
Depends { name: "cpp" }
cpp.includePaths: [product.sourceDirectory]
}
}
The app.qbs file:
import qbs 1.0
Product {
qbs.profiles: ["arm-gcc"] //I added only this line
type: "application"
consoleApplication: true
files : [ "main.cpp" ]
Depends { name: "cpp" }
Depends { name: "mylib" }
}
The app build fails. Qbs wrongly tries to link to the "gcc" version of the library instead of the "arm-gcc" version, as you can see in the log:

The following products could not be built for configuration default:
app
The build fails only when selecting one profile in the app.qbs file, and this profile should not be the first profile in the qbs.profiles line in the lib.qbs file.
When selecting two or more profiles - the build succeeds.
My analysis:
I think this problem is related to multiplexing:
The lib.qbs contains more than one profile. This turns on multiplexing when building the library, which, in turn, adds additional 'multiplexConfigurationId' to the build-directory name (moduleloader.cpp).
The app.lib contains only one profile, so multiplexing is not turned on and the build-directory name does not get the extra string.
The problem can be solved by changing the code (moduleloader.cpp) so that multiplexing is turned even if there is only one profile i.e. with the following patch:
--- moduleloader.cpp 2018-10-24 16:17:43.633527397 +0300
+++ moduleloader.cpp.new 2018-10-24 16:18:27.541370544 +0300
## -872,7 +872,7 ##
= callWithTemporaryBaseModule<const MultiplexInfo>(dummyContext,
extractMultiplexInfoFromProduct);
- if (multiplexInfo.table.size() > 1)
+ if (multiplexInfo.table.size() > 0)
productItem->setProperty(StringConstants::multiplexedProperty(), VariantValue::trueValue());
VariantValuePtr productNameValue = VariantValue::create(productName);
## -891,7 +891,7 ##
const QString multiplexConfigurationId = multiplexInfo.toIdString(row);
const VariantValuePtr multiplexConfigurationIdValue
= VariantValue::create(multiplexConfigurationId);
- if (multiplexInfo.table.size() > 1 || aggregator) {
+ if (multiplexInfo.table.size() > 0 || aggregator) {
multiplexConfigurationIdValues.push_back(multiplexConfigurationIdValue);
item->setProperty(StringConstants::multiplexConfigurationIdProperty(),
multiplexConfigurationIdValue);
This worked for my use case. I don't know if it make sense in a broader view.
Finally, the questions:
Does it all make sense?
Is this a normal behavior?
Is this use-case simply not supported?
Is there a better solution?
Thanks in advance.
Yes, the default behavior with multiplexing is that the a non-multiplexed product depends on all variants of the dependency. In general, there is no way for a user to change that behavior, but there should be.
However, luckily for you, profiles are special:
Depends { name: "mylib"; profiles: "arm-gcc" }
This should fix your problem.

Boost-build/BJam language - checking the value of a flag

I need to edit a .jam file used by boost-build for a specific kind of projects. The official manual on BJAM language says:
One of the toolsets that cares about DEF files is msvc. The following line should be added to it. flags msvc.link DEF_FILE
;
Since the DEF_FILE variable is not used by the msvc.link action, we need to modify it to be: actions link bind DEF_FILE { $(.LD) ....
/DEF:$(DEF_FILE) .... } Note the bind DEF_FILE part. It tells bjam to
translate the internal target name in DEF_FILE to a corresponding
filename in the link
So apparently just printing DEF_FILE with ECHO wouldn't work. How can it be expanded to a string variable or something that can actually be checked?
What I need to do is to print an error message and abort the build in case the flag is not set. I tried:
if ! $(DEF_FILE)
{
errors.user-error "file not found" ;
EXIT ;
}
but this "if" is always true
I also tried putting "if ! $_DEF_FILE {...}" inside the "actions" contained but apparently it is ignored.
I am not sure I understand the global task you have. However, if you wanted to add checking for non-empty DEF_FILE -- expanding on the documentation bit you quote, you need to add the check in msvc.link function.
If you have a command line pattern (specified with 'actions') its content is what is passed to OS for execution. But, you can also have a function with the same name, that will be called before generating the actions. For example, here's what current codebase have:
rule link.dll ( targets + : sources * : properties * )
{
DEPENDS $(<) : [ on $(<) return $(DEF_FILE) ] ;
if <embed-manifest>on in $(properties)
{
msvc.manifest.dll $(targets) : $(sources) : $(properties) ;
}
}
You can modify this code to additionally:
if ! [ on $(<) return $(DEF_FILE) ] {
ECHO "error" ;
}

Cross platform way of testing whether a file is a directory

Currently I have some code like (condensed and removed a bunch of error checking):
dp = readdir(dir);
if (dp->d_type == DT_DIR) {
}
This works swimmingly on my Linux machine. However on another machine (looks like SunOS, sparc):
SunOS HOST 5.10 Generic_127127-11 sun4u sparc SUNW,Ultra-5_10
I get the following error at compile time:
error: structure has no member named `d_type'
error: `DT_DIR' undeclared (first use in this function)
I thought the dirent.h header was crossplatform (for POSIX machines). Any suggestions.
Ref http://www.nexenta.org/os/Porting_Codefixes:
The struct dirent definition in solaris does not contain the d_type field. You would need to make the changes as follows
if (de->d_type == DT_DIR)
{
return 0;
}
changes to
struct stat s; /*include sys/stat.h if necessary */
..
..
stat(de->d_name, &s);
if (s.st_mode & S_IFDIR)
{
return 0;
}
Since stat is also POSIX standard it should be more cross-platform. But you may want to use if ((s.st_mode & S_IFMT) == S_IFDIR) to follow the standard.
