2010-08-19CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread insteadDaniel Dunbar
of the current thread. This has the unfortunate effect that assert() and abort() will end up bypassing our crash recovery attempts. We work around this for anything in the same linkage unit by just defining our own versions of the assert handler and abort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111583 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-27Factor out the handler work from SignalHandler into a helper function,Dan Gohman
and change llvm::sys::RunInterruptHandlers to call that function directly instead of calling SignalHandler, because the rest of SignalHandler invokes side effects which aren't appropriate, including raising the signal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104896 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-17Fix a false-positive memory leak in code using RemoveFileOnSignal(). BecauseJeffrey Yasskin
libstdc++'s std::string class points to the interior of an allocation, valgrind reports strings still alive at program termination as possible leaks. I didn't use a ManagedStatic for this because System can't depend on Support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98716 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-07When a crash signal is delivered do two things: remove all of ourChris Lattner

arbitrary functions to be run when a crash happens. Delete RemoveDirectoryOnSignal as it is dead and has never had clients.

2007-03-29For PR789:Reid Spencer
Make the sys::Path::getFileStatus function more efficient by having it return a pointer to the FileStatus structure rather than copy it. Adjust uses of the function accordingly. Also, fix some memory issues in sys::Path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35476 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-07Make the removal of files use Path::eraseFromDisk just like it does forReid Spencer
the removal of directories. Using std::remove is indiscriminate and can lead to the removal of things like /dev/null if run as root. The Path::eraseFromDisk method ensures that we only ever remove regular files or directories, but never character or block special nodes. This should clear up the problem with usage like: llvm-as -o /dev/null which is used in the llvm-test makefiles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29540 91177308-0d34-0410-b5e6-96231b3b80d8

the Signals module that registered the handlers would cause the stack trace to be generated. Now, you must explicitly call PrintStackTraceOnErrorSignal in order for that to happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28810 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-08Final Changes For PR495:Reid Spencer
This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22354 91177308-0d34-0410-b5e6-96231b3b80d8
2005-07-07For PR495:Reid Spencer
Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8
