| | | | | | | | | | | | | | multibyte character support: - In CHadd(), avoid writing past the end of the character set bitmap when the opposite-case counterpart of wide characters with values less than NC have values greater than or equal to NC. - In CHaddtype(), fix a braino that caused alphabetic characters to be added to all character classes!

* Refactor a bunch of scheduler code to give basically the same behaviourJulian Elischer2004-09-051-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | but with slightly cleaned up interfaces. The KSE structure has become the same as the "per thread scheduler private data" structure. In order to not make the diffs too great one is #defined as the other at this time. The KSE (or td_sched) structure is now allocated per thread and has no allocation code of its own. Concurrency for a KSEGRP is now kept track of via a simple pair of counters rather than using KSE structures as tokens. Since the KSE structure is different in each scheduler, kern_switch.c is now included at the end of each scheduler. Nothing outside the scheduler knows the contents of the KSE (aka td_sched) structure. The fields in the ksegrp structure that are to do with the scheduler's queueing mechanisms are now moved to the kg_sched structure. (per ksegrp scheduler private data structure). In other words how the scheduler queues and keeps track of threads is no-one's business except the scheduler's. This should allow people to write experimental schedulers with completely different internal structuring. A scheduler call sched_set_concurrency(kg, N) has been added that notifies teh scheduler that no more than N threads from that ksegrp should be allowed to be on concurrently scheduled. This is also used to enforce 'fainess' at this time so that a ksegrp with 10000 threads can not swamp a the run queue and force out a process with 1 thread, since the current code will not set the concurrency above NCPU, and both schedulers will not allow more than that many onto the system run queue at a time. Each scheduler should eventualy develop their own methods to do this now that they are effectively separated. Rejig libthr's kernel interface to follow the same code paths as linkse for scope system threads. This has slightly hurt libthr's performance but I will work to recover as much of it as I can. Thread exit code has been cleaned up greatly. exit and exec code now transitions a process back to 'standard non-threaded mode' before taking the next step.

* Some old tar archives rely on "regular-file-plus-trailing-slash" toTim Kientzle2004-09-041-12/+22
| | | | | | | | | | | | | | | | | | denote a directory. Unfortunately, in the presence of GNU or POSIX extensions, this code was checking the truncated filename stored in the regular header rather than the full filename stored in the extended attribute. As a result, long filenames with '/' in just the right position would trigger this check and be erroneously marked as directories. Move the check so it only considers the full filename. Note: the check can't simply be disabled for archives that contain these extensions because there are some very broken archivers out there.

* Reset the seek pointer to 0 when a file is successfully opened,Ian Dowse2004-09-041-0/+2
| | | | | | | | | | | | | | | | since otherwise the initial seek offset will contain the directory offset of the filesystem block that contained its directory entry. This bug was mostly harmless because typically the directory is less than one filesystem block in size so the offset would be zero. It did however generally break loading a kernel from the (large) kernel compile directory. Also reset the seek pointer when a new inode is opened in read_inode(), though this is not actually necessary now because all callers set it afterwards. Notes: svn path=/head/; revision=134760

| | | | | | | | | | | | | | | | _mcount() stub when profiling is enabled. Emit this code sequence for assembly routines as welli (MCOUNT definition in <machine/asm.h>. We do not pass the GOT entry however as the 4th argument, because it's not used. The _mcount() stub calls __mcount(), which does the actual work. Define _MCOUNT_DECL to define __mcount. We do not have an implementation of mcount(), so we define MCOUNT as empty, but have a weak alias to _mcount() in _mcount.S. Note that the _mcount() stub in the kernel is slightly different from the stub in userland. This is because we do not have to worry about nested routines in the kernel.

* struct tm.tm_year is listed as 'years since 1900', and is signed. OnPeter Wemm2004-08-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | 64 bit systems, years roughly -2^31 through 2^31 can be represented in time_t without any trouble. 32 bit time_t systems only range from roughly 1902 through 2038. As a consequence, none of the date munging code for all the various calendar tweaks before then is present. There are other problems including the fact that there was no 'year zero' and so on. So rather than get excited about trying to figure out when the calendar jumped by two weeks etc, simply disallow negative (ie: prior to 1900) years. This happens to have an important side effect. If you bzero a 'struct tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'. This happens to be representable (after canonification) in 64 bit time_t space. Zero tm structs are generally an error and mktime normally returns -1 for them. Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie: year -1. This conveniently trips the negative year test above, which means we can trivially detect the null 'tm' struct. This actually tripped up code at work. :-/ (Don't ask) Notes: svn path=/head/; revision=134231
