goto break; != break;

2002-11-17T08:54:29Z

I've no idea if this is the right behavior for the library, but this at least fixes the build, and matches what seems to be alfred's intent in the commit message for 1.19.

Rework the sysconf(3) interaction with aio:

2002-11-17T04:15:34Z

sysconf.c: Use 'break' rather than 'goto yesno' in sysconf.c so that we report a '0' return value from the kernel sysctl. vfs_aio.c: Make aio reset its configuration parameters to -1 after unloading instead of 0. posix4_mib.c: Initialize the aio configuration parameters to -1 to indicate that it is not loaded. Add a facility (p31b_iscfg()) to determine if a posix4 facility has been initialized to avoid having to re-order the SYSINITs. Use p31b_iscfg() to determine if aio has had a chance to run yet which is likely if it is compiled into the kernel and avoid spamming its values. Introduce a macro P31B_VALID() instead of doing the same comparison over and over. posix4.h: Prototype p31b_iscfg().

Provide more correct default values for sysconf(3) reporting of the AIO

2002-11-16T06:35:20Z

subsystems capabilities: _SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX _SC_AIO_MAX returns the default _POSIX_AIO_MAX _SC_AIO_PRIO_DELTA_MAX returns the default of 0 Without these adjustments the values returned are -1 even when the aio side of the kernel returns '0' for them which is incorrect.

Update limits and configuration parameters for 1003.1/TC1/D6.

2002-10-27T18:03:02Z

Implement new sysconf keys. Change the implenentation of _SC_ASYNCHRONOUS_IO in preparation for the next set of changes. Move some limits which had been in to where they belong. They had only ever been in syslimits.h to provide for the kernel implementation of the CTL_USER MIB branch, which went away with newsysctl years ago. (There is a #error in which I will downgrade in the next commit.)

Initiate deorbit burn sequence for sysctl CTL_USER MIB branch.

Use the correct constants directly from sysconf() rather than calling sysctl() to tell us the (still compiled-in) value. Leave the CTL_POSIX1B stuff alone for now (but I'd like to see this replaced with a single structure returning all of the relevant information). Implement all of the keys from 1003.1-2001 that we can. Ensure that the build will break if someone redefines an option constant to zero without implementing the necessary presence-detection logic here. (4 of 5)

Don't bother asking the kernel about _SC_FSYNC; it's not optional.

A break after a return is useless.

Fix SCM ID's.

Add support for sysconf(_SC_NPROCESSORS_CONF) and sysconf(_SC_NPROCESSORS_ONLN).

After one too many PRs on the subject, bite the bullet and define IOV_MAX

and its associated constants. Implement _SC_IOV_MAX in the usual way. Be a bit sloppy about the namespace question; this should get cleared up in time for 5.0. MFC after: 1 month
