jnr-posix's Issues

dev_major and dev_minor on Windows

It appears that the dev_major, dev_minor, rdev_major and rdev_minor methods from the File::Stat class try to return numeric values on MS Windows. It seems they're using the results of the dev and rdev methods, which return a drive number (0, 1, or 2 for A:, B: or C: drives, for example). The dev and rdev methods themselves are fine - that matches MRI.

However, in MRI these methods all return nil as these have no meaningful value on Windows.

Add getrlimit and setrlimit

Please add getrlimit and setrlimit

No gettimeofday on Windows

For jruby/jruby#4393 we added gettimeofday to jnr-posix. Unfortunately, it is not supported on Windows (jruby/jruby#4565).

I'm doing a workaround that uses System.currentTimeMillis on Windows. This won't preserve microsecond accuracy, but it will work.

We need to do the additional logic to make an appropriate gettimeofday on Windows. I found at least one SO post describing how: http://stackoverflow.com/questions/1676036/what-should-i-use-to-replace-gettimeofday-on-windows

SEGV due to posix_spawnattr_init called on a too small allocation

jnr-posix/src/main/java/jnr/posix/BaseNativePOSIX.java

Line 588 in e247624

Pointer nativeSpawnAttributes = Memory.allocateDirect(getRuntime(), 128);

expects sizeof(posix_spawnattr_t) to be <= 128.

But on my system (Linux localhost.localdomain 4.9.4-100.fc24.x86_64 #1 SMP Tue Jan 17 19:08:56 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux):

#include <stdio.h>
#include <spawn.h>

int main() {
	printf("posix_spawn_file_actions_t: %ld\n", sizeof(posix_spawn_file_actions_t));
	printf("posix_spawnattr_t: %ld\n", sizeof(posix_spawnattr_t));
	return 0;
}

prints:

posix_spawn_file_actions_t: 80
posix_spawnattr_t: 336

How should this be dealt with?
Is there a way to get the value of sizeof(posix_spawnattr_t) per platform?

FindFirstFileW on 32 bit JVM crashes

we have a FIXME: shortcutting WindowsPOSIX.stat to call win32's posix stat fallback. This is undesirable since it does not support UNC nor long paths. If I remove this work around in cases where GetFileAttributesExW fails we crash in fallback call to FindFirstFileW.

The crash itself appears to be us populating something incorrectly but windows itself seems very good at not changing word sizes between 32/64 so I am baffled by 32 fails and 64 works.

Wrong statVersion passed to __fxstat64

The code in LinuxPOSIX.java passed version "0" for 64 bit x86 Linux. But I believe this is an error, and needs to be 1 (see _STAT_VER in glibc's sysdeps/unix/sysv/linux/x86/bits/stat.h, or just compile a test program and print out _STAT_VER).

This doesn't cause any problems because glibc's __fxstat64 actually never checks the version argument, but it nevertheless seems strange to give it the wrong version.

Another related question - it seems you always call __fxstat64, even on 32-bit platforms. So why do you need that 32-bit structure definition?

loading native POSIX failed

Hi,

I seem to be running into an issue when I run my app (using jnr-posix) from a jetty instance inside eclipse. It fails to load the native implementation, and falls back to the java implementation (see traceback below). It does seem to work if you run it from a shell (I'm on ubuntu 12.04 64-bit). Do you have a workaround for this?

Thanks!

JVM crash with threaded use of Etc::getgrnam

The JVM crashes on threaded use of Etc::getgrnam This happens on all versions of java 1.7 I tested with, e.g. the latest Oracle java 1.7 update 75. Tested with both jruby 1.7.8 and 1.7.19 on CentOS 6.6 A sample test program that will demonstrate the problem is:

require 'etc'

i = 1
while true do
  puts "Iteration #{i}"
  i = i + 1
  threads = []
  10.times do
    threads << Thread.new do
      Etc::getgrnam('users')
    end
  end
  threads.each do |thr|
    thr.join
  end
end

This always crashes for me, usually it takes less than 200 iterations or so:

posix_spawnp() should return int, not long

posix_spawnp() should return an int and not a long.
https://github.com/jnr/jnr-posix/blob/master/src/main/java/jnr/posix/POSIX.java#L128-L133

This is as specified by the man page:

int posix_spawn(pid_t *pid, const char *path,
                       const posix_spawn_file_actions_t *file_actions,
                       const posix_spawnattr_t *attrp,
                       char *const argv[], char *const envp[]);

Of course, one problem is that a native int might be 4 bytes, 8 bytes or something different than the Java 4-bytes int. But many other functions have this problem, so I suppose primitive types take the native meaning and not necessarily Java's.

This means on Solaris, the returned value is actually wrong, and the real value is (returnValue >> 32).

setrlimit() and getrlimit() missing?

Do I overlook something or are setrlimit() and getrlimit() missing?

BaseNativePOSIX utimes/futimes API is not compatible with OpenBSD/i386

The BaseNativePOSIX utimes/futimes function uses long[] types for the atimeval and mtimeval arguments (see

jnr-posix/src/main/java/jnr/posix/BaseNativePOSIX.java

Line 353 in cc37a63

public int utimes(String path, long[] atimeval, long[] mtimeval) {

). On OpenBSD, struct timeval contains a time_t member for the seconds and a long member for the microseconds. Unfortunately, on OpenBSD/i386, the time_t type uses long long (64-bit), not long (32-bit). So you can't store the values in a long[] type.

Because it uses an incorrect size for the type, in general usage, the utimes/futimes function results in the modification time of the file being set to 0.

I think the API of utimes/futimes needs to be changed so that it takes a OS-dependent struct for the atimeval and mtimeval arguments, instead of using long[].

Support for Raspberry Pi?

I'm here due to jruby/jruby#3244.

It looks like jnr-posix fails to load native POSIX on Raspbian (Raspberry Pi OS), and I'm not exactly sure why. Unfortunately, I need process killing functionality, which the JavaPOSIX fallback doesn't support.

Are there any steps we can take to make it supported? Happy to lend a hand if necessary.

OpenBSD structure layout wrong after recent OpenBSD changes

Recently, OpenBSD moved from a 32-bit time_t to a 64-bit time_t, with some other changes as well:

Commit message: http://marc.info/?l=openbsd-cvs&m=137637321205010&w=2)
Changes to sys/_types.h: http://www.openbsd.org/cgi-bin/cvsweb/src/sys/sys/_types.h.diff?r1=1.5;r2=1.6
Changes to sys/stat.h: http://www.openbsd.org/cgi-bin/cvsweb/src/sys/sys/stat.h.diff?r1=1.22;r2=1.23

After this change in OpenBSD, JRuby will not fully install, as it fails when trying to install rake (http://pbot.rmdir.de/JDuDNBBfrpVBb_EQKuJSVA).

I believe I have a diff that brings the jnr-posix structure layouts in-line with OpenBSD-current, but I haven't tested it yet (http://pastie.org/pastes/8260655/text). However, a straight patch approach may be unacceptable as it would mean that jnr-posix would then not work correctly on older OpenBSD versions. Would that be a problem?

If it would be a problem, do you have a recommendation on the best way to fix this such that both older and newer OpenBSD would run correctly? Should we have code for both OpenBSD layouts, and pick which one to use at runtime? If so, should such a check go in POSIXFactory.java, and do you have an idea about how to check (such as using the operating system version)?

maven package command fails because GroupTest.java fails

First of all I'm a Linux/Java/GIT newbie. I just pulled your jnr-posix package down to my Fedora 21 desktop and then ran 'mvn package'. That had a test failure and I guess a single test failure also causes a failure in generating the jar. I did some searching and found:

http://pkgs.fedoraproject.org/cgit/jnr-posix.git/commit/?h=f22

Not quite sure what that link is. I guess you're doing some work with the Fedora project? At any rate I saw the comment about changing 'nogroup' to 'root' in GroupTest.java so I made the change on the source I pulled down. That fixed the build. I guess you should fix GroupTest.java on github.

Thanks,
Nick

getgroups() is incorrect on Linux and Solaris

@chrisseaton @nirvdrum
Specifically, on platforms where gid_t is 4 bytes, declaring getgroups as
int getgroups(int size, long[] groups);
https://github.com/jnr/jnr-posix/pull/82/files#diff-692c666e6bb39b5fe2f2f13854994febR168
is incorrect (it will return 2 groups per long and read out of bounds).

Probably some kind of gid_t type should be used instead.

Seemingly (on Windows 7) stat is not implemented in jnr-posix

It is implemented, of course, but there is a problem that raises an exception, along these lines, when using the native implementation. I can reproduce it; I know how it arises; but I don't understand jnr-posix well enough to offer a patch. This problem is relevant for us on the Jython project (see http://bugs.jython.org/issue2145)

The root of the problem (and it may be a jnr-ffi issue after all) is that during the construction of the interface for LibC, round about here:
https://github.com/jnr/jnr-ffi/blob/master/src/main/java/jnr/ffi/LibraryLoader.java#L262
the functionMapper supplied by jnr-posix gets dropped, and so methods in the constructed interface only have their own native names, not the mapped names carefully supplied by jnr-posix.

When it fails, the test runs like this:

>java -cp bin;lib\* StatTest
Exception in thread "main" java.lang.IllegalStateException: stat is not implemented in jnr-posix
        at jnr.posix.util.DefaultPOSIXHandler.unimplementedError(DefaultPOSIXHandler.java:28)

        at jnr.posix.CheckedPOSIX.stat(CheckedPOSIX.java:265)
        at jnr.posix.LazyPOSIX.stat(LazyPOSIX.java:267)
        at StatTest.main(StatTest.java:25)

The libraries on my classpath are:

>dir/b lib
asm-4.0.jar
jffi-1.2.7-native.jar
jffi-1.2.7.jar
jnr-constants-0.8.5.jar
jnr-ffi-1.0.10.jar
jnr-ffi-1.0.10.zip
jnr-posix-3.0.1-sources.jar
jnr-posix-3.0.1.jar

I've a couple of source zip/jars in there to support debugging. The Java version is:

>java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

If I delete the native jar (contains the DLLs) jnr-posix reverts to a Java implementation and it works:

            System.out.println(fs);

        } catch (IOException e) {
            System.err.println(e.getStackTrace());
        }
    }

}

Ability to disable fallback to JavaPOSIX

I would like a way to get POSIXFactory to handle failure to load the native POSIX by propagating the Throwable, not returning a JavaPOSIX.

The caller cannot function with the limited functionality of JavaPOSIX. It would be better to fail fast with a useful exception than to delay failure with an uninformative "not implemented" error.

gethostname() not implemented

The gethostname() function is in the POSIX manual, however it is not specified in the project's POSIX interface (and also is annoyingly not present in the JDK itself).

This might be a useful addition; also it should be fairly trivial to add.

Implement `chdir`

We need this to have Kernel#exec working properly in JRuby. (See http://jira.codehaus.org/browse/JRUBY-6994.)

Java 8 breakage

We use jnr-posix to relinquish root privileges after opening server sockets (that is, listening sockets < 1024). With java 8, we get

java.lang.IllegalStateException: getpwnam unimplemented is not implemented in jnr-posix at jnr.posix.util.DefaultPOSIXHandler.unimplementedError(DefaultPOSIXHandler.java:28) at jnr.posix.JavaPOSIX.getpwnam(JavaPOSIX.java:176) at jnr.posix.LazyPOSIX.getpwnam(LazyPOSIX.java:198)

This worked fine in previous JREs.

SpawnFileAction.open opens wrong filename

I have a problem with jnr-posix-3.0.29 running on CentOS 7 using JDK 1.8. I'm trying to spawn processes using posix_spawnp, with stdout redirected to a file. Unfortunately, it looks like the filename I provide to SpawnFileAction.open is not honored, and the output is written to a randomly named file (usually with unprintable characters) in the current directory.

I have created a minimum working example that shows the problem. One directory has working C code that does what I want, the other directory has Java JNR code that exhibits the problem.

Using strace, the C code file open looks something like this:
open("/tmp/foo-log", O_WRONLY|O_CREAT|O_TRUNC, 0644) = 3
while the JNR code produces strace output like this:
open("\300\216mu;\177", O_WRONLY|O_CREAT|O_TRUNC, 0644) = 12 where that first parameter should be /tmp/bar-log. Could the filename be uninitialized memory?

Any thoughts on what the problem might be? I have single-stepped the code in Eclipse, and on the Java side it looked reasonable. On the posix_spawn_file_actions_addopen man page I saw this tidbit: "The string described by path shall be copied by the posix_spawn_file_actions_addopen() function." not sure if that is relevant.

P.S. To clean up the files with unprintable names ls -lb and rm $'filename' are helpful :)

JavaSecuredFile has a Google copyright

JavaSecuredFile.java was added by @olabini in (commit redacted to reduce tainting potential) with an appropriately tri-licensed header but a Google copyright. We can't trace the lineage of this file, because it appeared all at once and does not appear to exist anywhere else in the world.

@olabini Was the Google copyright a mistake here, or did you actually get this from some Google code?

This is a blocker for some folks planning to embed jnr-posix.

NOTE: Anyone attempting to use my clean-room description below to reimpl this file MUST NOT have ever seen the original. So don't go looking for it.

read/write methods restrict number of bytes to 32 bit

AFAICT the underlying read(), write(), pread(), and pwrite() are supposed to be able to accept size_t as number of bytes argument and return ssize_t for number of bytes written. But the POSIX class is restricting the values to 32 bit Java int. Also the offset arguments for pread() and pread() are of type off_t which is often 64 bit.

    final int r = posix.execv("/bin/sh", new String[]{"/bin/sh"});
    if (r == -1) {
      LOG.error("execv: {}", strerror.strerror(posix.errno()));

  }
}

Running the program yields:

21:39:40.482 [main] DEBUG com.io7m.ja.MainExecv - creating libc loader
21:39:40.566 [main] ERROR com.io7m.ja.MainExecv - execv: Bad address

Tracing the program with strace shows:

[pid 26245] execve("/bin/sh", [0x68732f6e69622f, 0x7f1900000000, "/bin/sh"], [/* 52 vars */] <unfinished ...>

It looks as though the native code is not being passed the array of strings correctly. I'm not sure if I'm misusing the interfaces, or if the strace output is just misleading. Note that
0x68732f6e69622f == 68 72 2f 6e 69 62 2f == 'h' 's' '/' 'n' 'i' 'b' /...

Hang while handling SIGSEGV signal

Hi,

I am trying to catch and handle SIGSEGV by using jnr-posix to get thread dumps and some other informations before crash. I am using the following code sample:

POSIX posix = POSIXFactory.getPOSIX();
posix.signal(Signal.SIGSEGV, new SignalHandler() {
    @Override
    public void handle(int i) {
        System.out.println("handle: " + i);
    }
});
Unsafe unsafe = ...
unsafe.putLong(0l, 0l);

But when I run the code, it hangs while executing unsafe.putLong(0l, 0l);.
When I have debugged, as far as I see, signal is handled, jnr.ffi.provider.jffi.NativeClosureFactory$ClosureReference is created with correct referent which contains my handler as wrapped but then closureReference.get() always returns null inside NativeClosureProxy::getCallable() so seems that there is an infinite loop because of this.

My operating system is MacOSX and using JDK 1.8.0_60.
jnr-posix version is 3.0.23.

Thanks in advance.

Regards.

jnr.posix.POSIX.fstat(int, FileStat) fails on Windows

The following test unfortunately fails on Windows:

    @Test
    public void filestatDescriptor2() throws Throwable {
        File f = File.createTempFile("stat", null);

        try {
            int fd = posix.open(f.getAbsolutePath(), 0, 438);
            FileStat stat = posix.allocateStat();
            int result = posix.fstat(fd, stat);
            assertEquals(0, result);
            assertEquals(0, stat.st_size());
        } finally {
            f.delete();
        }

    }

With the following exception:

java.lang.IllegalArgumentException: instance of class jnr.posix.WindowsRawFileStat is not a struct
	at jnr.posix.BaseNativePOSIX$2.toNative(BaseNativePOSIX.java:746)
	at jnr.posix.BaseNativePOSIX$2.toNative(BaseNativePOSIX.java:1)

	at jnr.posix.CheckedPOSIX.fstat(CheckedPOSIX.java:129)
	at jnr.posix.LazyPOSIX.fstat(LazyPOSIX.java:126)
[..]

The call to jnr.posix.POSIX.fstat(int, FileStat) currently isn't covered in jnr.posix.FileStatTest, which is why this (likely) bug may have gone unnoticed yet.

Please add dup function

Add readlink(3) method

Please add a readlink(3) method: http://linux.die.net/man/3/readlink

lseek return type should be long on 64 bit platforms

off_t is a long on 64 bit platforms, but the POSIX interface lists it as an int. It should be updated to match the platform size on x86_64 systems. Discovered via jruby/jruby#3664

Use jnr-ffi function to get platform-specific C library name

This change in jnr-enxio shows how we'd like to start getting the C library, as a utility of jnr-ffi: jnr/jnr-enxio#12

We need to do the same in jnr-posix.

Add support for musl libc

Linux is not only glibc, there are also other C libraries like musl libc or uClibc.

I’m trying to run JRuby on Alpine Linux that uses musl libc and for example irb doesn’t work (see log at the end). I found two native libraries in JRuby, jffi and jansi (bundled in jline.jar), recompiled them against musl and loaded them using appropriate properties, but JRuby is still trying to load libcrypt.so and complains about fstat. I spent many hours trying to figure out what’s going on and what is trying to load libcrypt.so.

Then I finally found jnr-posix. I’ve tried to run tests and it failed in the same way (see log at the end).

Could you please make jnr-posix compatible with musl libc? I can prepare you setup for testing against musl on Travis, if you like.

EDIT: Heureka! I’ve just tried very desperate thing – symlink libc.so -> libcrypt.so… and it works! jirb now loads without any error and all jnr-posix tests pass! 🎆
