Thus, the execution of an addopen action that was created by a call to posix_spawn_file_actions_addopen( ) that specifies a relative path will be affected by the execution of a chdir or fchdir action that was created by a previous call to posix_spawn_file_actions_addchdir( ) or posix_spawn_file_actions_addfchdir( ). Likewise, a relative path passed to posix_spawn( ) will be affected by the last chdir or fchdir action in the file action list. The paragraph still occurs in the text proposed to be added in the new interface addition after page 1460, but was moved from DESCRIPTION to APPLICATION USAGE.

Since the existing Solaris implementation uses const char* for the _addchdir() name, we'd definitely want to spell things as addfchdir() for an int version rather than risk confusion why addchdir() takes a different type than addchdir_n(). But with that said, here's an exploratory patch originally proposed to glibc implementing an fchdir action under the name addchdir() (but which never went anywhere at the time) - 8 years ago! https://sourceware.org/ml/libc-alpha/2010-08/msg00107.html Issue History Date ModifiedUsername FieldChange == 2018-09-07 18:39 eblake New Issue 2018-09-07 18:39 eblake Name => Eric Blake 2018-09-07 18:39 eblake Organization => Red Hat 2018-09-07 18:39 eblake User Reference=> posix_spawn.chdir 2018-09-07 18:39 eblake Section => posix_spawn 2018-09-07 18:39 eblake Page Number => 1452 ff. 2018-09-07 18:39 eblake Line Number => 48227 ff. 2018-09-07 18:39 eblake Interp Status => --- 2018-09-07 18:39 eblake Relationship added related to 0001044 2018-09-07 18:44 eblake Desired Action Updated 2018-09-07 18:46 eblake Desired Action Updated 2018-09-07 18:49 eblake Desired Action Updated 2018-09-07 18:51 eblake Desired Action Updated 2018-09-07 18:53 eblake Desired Action Updated 2018-09-07 18:55 eblake Desired Action Updated 2018-09-07 18:55 eblake Tag Attached: issue8 2018-09-07 19:02 eblake Note Added: 0004109 2018-09-07 19:04 eblake Desired Action Updated 2018-09-07 19:29 eblake Desired Action Updated 2018-09-07 19:35 eblake Description Updated 2018-09-07 22:18 eblake Note Added: 0004110 2018-09-07 22:44 eblake Note Added: 0004111 ==

[1003.1(2016)/Issue7+TC2 0001208]: calling chdir as part of posix_spawn
The following issue has been SUBMITTED. == http://austingroupbugs.net/view.php?id=1208 == Reported By:eblake Assigned To: == Project:1003.1(2016)/Issue7+TC2 Issue ID: 1208 Category: System Interfaces Type: Enhancement Request Severity: Objection Priority: normal Status: New Name: Eric Blake Organization: Red Hat User Reference: posix_spawn.chdir Section:posix_spawn Page Number:1452 ff. Line Number:48227 ff. Interp Status: --- Final Accepted Text: == Date Submitted: 2018-09-07 18:39 UTC Last Modified: 2018-09-07 18:39 UTC == Summary:calling chdir as part of posix_spawn Description: One notable missing feature from posix_spawn is the ability to change the initial working directory of the new process. Of course, in the common case, it is possible to exec a shim process that will change the directory (GNU coreutils has 'env -C dir program ...' that will do this, but the standard itself does not have such a shim program, so users have to come up with their own). But even more complex is the fact that posix_spawn can change access permissions with PSOIX_SPAWN_RESETIDS, such that the parent may have permission to change to a particular directory, but the child with a different id cannot do so. There is also the case that a multi-threaded parent process can use openat() to open files relative to a particular directory without changing the global state of the current working directory, but there is no interface for openat() within posix_spawn (and it may be prohibitively expensive to convert a relative name into an absolute one). Thus, it can be argued that changing the directory needs to be directly part of posix_spawn(). Solaris has implemented an extension for chdir with a _np suffix (non-portable), and documents that relative names for posix_spawn(,path) and posix_spawnp(,file) are interpreted to the working directory selected for the child: https://docs.oracle.com/cd/E86824_01/html/E54766/posix-spawn-file-actions-addchdir-np-3c.html I'm proposing that we standardize this, but drop the _np suffix (since by standardizing it, it will no longer be non-portable), and also add a counterpart for fchdir. The addition of fchdir makes it possible to simulate openat semantics without actually needing to add posix_spawn_file_actions_addopenat. Note that I did not standardize the notion of a chroot file action (in part due to no existing practice), although such an extension may still make sense. Fix a couple of issues in posix_spawn_file_addclose while at it: you can't delete open/close actions from an existing file_actions object, only add more; and ENOMEM should be a 'shall fail' rather than 'may fail' error to match posix_spawn_file_adddup2. Yes, the additions to the XRAT example are just as borked as the existing implementation for handling an addopen action at lines 126723-126763 and 126852-126860 (very easy to write beyond end of fixed-length array, parse failure on filename containing '*', failure to fail with EBADF for negative filedes, etc) - but being consistently bad in something that is mainly for demo purposes isn't the end of the world. The use of _exit() instead of exit() in the example matches the resolution for http://austingroupbugs.net/view.php?id=1044.
