2014-07-09Add tests of filelib and symlinksSiri Hansen
This commit complements 769996c0cd4cb68c157e39de725642f209ed7423 and adds tests for the following problems introduced by f11aabdc9fec593c31e6c4f3fa25c1707e9c35df: Given the symlink 'dirlink' pointing to an existing dir, then - filelib:is_regular("dirlink") -> false - filelib:is_dir("dirlink") -> false Given the symlink 'filelink' pointing to an existing file, then - filelib:is_regular("filelink") -> false - filelib:is_file("filelink") -> false - filelib:last_modified("filelink") and filelib:filesize("filelink") return the info of the link and not the file Given the symlink "broken_symlink" pointing to a non-existing file, then - filelib:wildcard("broken_symlink",File) -> []
2014-07-09Fix handling of broken symlinks in filelibAnthony Ramine
This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never follow symlinks. This fixed wildcard/1 but broke every other function using eval_read_file_info/2. Reported-by: Louis-Philippe Gauthier Reported-by: Danil Zagoskin

* bjorn/kernel/remove-file_info-vestiges/OTP-11982: Remove documentation and stub for non-exist file:file_info/1
2014-06-13Remove documentation and stub for non-exist file:file_info/1Björn Gustavsson
file:file_info/1 was removed a long time ago, but its documentation was not removed.
2014-06-12Allow unsticking pre-loaded modulesBjörn Gustavsson
Commit ed06dd12ea74018b902a2c4c7924313d23cedb75 made pre-loaded modules (such as erlang) sticky, and also made it impossible to unstick them to prevent them from ever be reloaded. It turns out that there are tools that may want to instrument the erlang module (such as concuerror), so making it impossible to unstick modules is harsh. Therefore, revert the part of the commit that prevented unsticking the pre-loaded modules.
2014-06-04Make pre-loaded modules permanently stickyBjörn Gustavsson
Modules in the kernel, stdlib, and compiler applications are by default "sticky", meaning that the code server will refuse to re-load them. The pre-loaded modules (those that are part of the run-time system itself, such as 'erlang') are, however, not sticky. They used to be sticky a long time ago when the pre-loaded modules were part of the kernel application. Now they are part of the erts application. Since re-loading a pre-loaded module can be catastrophic (especially re-loading the 'erlang' module), the pre-loaded modules must be sticky. Furthermore, it should not be allowed to unstick them. The sticky_dir/1 test case in code_SUITE is never actually run and is broken. Rewrite it.
2014-05-26application_SUITE: Clean up the code after the test is doneBjörn Gustavsson
2014-05-26Teach code:del_path/1 to ignore superfluous slashesBjörn Gustavsson
The following sequence will NOT leave the code path unchanged: code:add_path("/some/app/"), . . . code:del_path("/some/app/") The reason is that code:add_path/1 will normalize the path name (removing the trailing slash), while code:del_path/1 does not normalize the path before searching for it in the code path.

2014-04-22Merge branch 'siri/ac-change_app_data/OTP-11864' into maintSiri Hansen
* siri/ac-change_app_data/OTP-11864: Store expanded config in application_controller:change_application_data
2014-04-11Store expanded config in application_controller:change_application_dataSiri Hansen
If the Config given to application_controller:change_application_data included other config files, it was only expanded for already existing (loaded) applications. If an upgrade added a new application which had config data in an included config file, the new application did not get correct config data. This is now changed so config data will be expanded for all applications.

2014-03-26ose: Prepare slave for running on OSELukas Larsson
This change relies on the assumption that all arguments before the last -- to the parent beam should be left as they are.
2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
The inet driver for OSE has to handle signals instead of selects and thus the wrappers for ready_input/output are a little bit different. However the majority of the inet code remains the same.

2014-03-20Verify runtime_dependencies when running 'otp_build patch_app'Rickard Green
2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.

file:set_cwd/1 accepts binaries as arguments, however the binaries must be properly encoded as per file:native_name_encoding/0. Also update the note under no_translation error to refer that passing a ISO-latin-1 encoded binary under any unicode file name encoding.
2014-03-07Support the LLVM backend in HiPEYiannis Tsiouris
Add flags to enable and use the LLVM backend: * to_llvm: use the LLVM pipeline for compilation (default optimization level is O3), * llvm_save_temps: save the intermediate files in current directory in order to be able to debug or optimize the LLVM assembly, * {to_llvm, O}: set the optimization level of LLVM opt and llc tools. Add some debug support to the loader; no semantic change intented.
2014-02-28prim_file_SUITE: Remove the short 5 seconds timetrap timeoutBjörn Gustavsson
Several tests cases would typically fail because of a timetrap timeout on our older test machines running with a Linux kernel with a lower version than 2.6.30 and the ext3 file system. In http://lwn.net/Articles/328363/, the author desribes peformance issues with ext3 that were fixed in 2.6.30. Since common_test nowadays has a default timetrap timeout, there is no need to explicitly set a timeout in each test case (except for prolonging the default timeout).
