4616 5654 d 15 h brambora /branches/snapshot/ Added functions for storing task checkpoint to udebug interface.
Added uspace task chkpnt that launches the snapshot creation.		  
4605 5658 d 17 h decky /branches/snapshot/ add task snapshoting branch  
4601 5660 d 15 h decky /trunk/uspace/lib/libc/ small fixes and coding style changes related to the new memory allocator  
4600 5660 d 15 h decky /trunk/uspace/lib/libc/generic/ implement simple first-fit memory allocator
(modified from original code by Petr Tuma, used under permission)		  
4599 5660 d 15 h decky /trunk/uspace/lib/libc/include/ define just the basic memory allocator interface  
4598 5660 d 15 h decky /trunk/uspace/lib/libc/ remove dlmalloc  
4591 5661 d 15 h decky /trunk/uspace/ add support for creating null devices on demand  
4590 5661 d 22 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 5662 d 9 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.		  
4586 5662 d 12 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4585 5662 d 12 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 5662 d 17 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4583 5662 d 19 h svoboda /trunk/uspace/ Fix chaos in block library.  
4572 5664 d 10 h svoboda /trunk/uspace/ Allow libblock to operate in write-through mode. With 'wtcache' mount option, FAT sets write-through mode on the cache.  
4556 5672 d 23 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		  
4553 5673 d 9 h jermar /trunk/uspace/lib/libblock/ Use fibril synchronization in libblock.  
4550 5673 d 10 h jermar /trunk/uspace/lib/libblock/ Disk I/O should be serialized until libblock switches to fibril synchronization.  
4549 5674 d 9 h svoboda /trunk/uspace/ Fix assorted warnings and tiny glitches.  
4542 5675 d 9 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 5675 d 9 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.
