4616 5600 d 23 h brambora /branches/snapshot/ Added functions for storing task checkpoint to udebug interface.
Added uspace task chkpnt that launches the snapshot creation.		  
4605 5605 d 1 h decky /branches/snapshot/ add task snapshoting branch  
4601 5606 d 23 h decky /trunk/uspace/lib/libc/ small fixes and coding style changes related to the new memory allocator  
4600 5606 d 23 h decky /trunk/uspace/lib/libc/generic/ implement simple first-fit memory allocator
(modified from original code by Petr Tuma, used under permission)		  
4591 5607 d 22 h decky /trunk/uspace/ add support for creating null devices on demand  
4590 5608 d 5 h decky /trunk/uspace/lib/libc/generic/io/ set buffering according to what file descriptor we are opening
(this still does not cover the full complexity of stdio buffering)		  
4587 5608 d 17 h jermar /trunk/uspace/ Implement stat() and VFS_IN_STAT.
Modify bdsh() to use stat() during ls.
In devfs, allow lookups that don't
specify one of L_FILE and L_DIRECTORY.		  
4585 5608 d 19 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4584 5609 d 1 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4556 5619 d 6 h decky /trunk/ define endianess externally to be able to exactly specify whether we are using UTF-32LE or UTF-32BE
quit messing with BOM in UTF-32		  
4549 5620 d 17 h svoboda /trunk/uspace/ Fix assorted warnings and tiny glitches.  
4542 5621 d 17 h jermar /trunk/uspace/ Handle pending input using only one fibril.
Relax serialization in console, keep your fingers crossed.
Do not create a new "pending" fibril after each received call.		  
4541 5621 d 17 h svoboda /trunk/uspace/ Stdio stream buffering (only for writing a.t.m.) Issue: Do we need two moving delimiters (head, tail) to recover from error or is one moving data delimiter enough, like in the current implementation? (Where the buffer must be drained as a whole, cannot do it part at a time.  
4535 5623 d 2 h jermar /trunk/uspace/lib/libc/ On condvar signal/broadcast, dequeue the waiting fibril from the waiters list.
Add FIBRIL_CONDVAR_INITIALIZE.		  
4528 5624 d 19 h svoboda /trunk/uspace/ Use 'fibril_local' modifier for fibril-local variables instead of '__thread'. Since it is decalred in fibril.h, it need not begin with '__'.  
4527 5624 d 21 h jermar /trunk/uspace/lib/libc/ Condition variables for fibrils.  
4526 5625 d 18 h jermar /trunk/uspace/lib/libc/ Implement readers-writer locks for fibrils.  
4523 5626 d 19 h decky /trunk/uspace/lib/libc/generic/io/ remove obsolete terminology  
4522 5626 d 19 h decky /trunk/uspace/lib/libc/ remove obsolete comment
cstyle		  
4516 5627 d 16 h jermar /trunk/uspace/lib/libc/ Add simple synchronization primitives to be used with fibrils.
Provided are mutexes and dummy rwlocks.
