4616 5438 d 9 h brambora /branches/snapshot/ Added functions for storing task checkpoint to udebug interface.
Added uspace task chkpnt that launches the snapshot creation.		  
4605 5442 d 11 h decky /branches/snapshot/ add task snapshoting branch  
4601 5444 d 9 h decky /trunk/uspace/lib/libc/ small fixes and coding style changes related to the new memory allocator  
4600 5444 d 9 h decky /trunk/uspace/lib/libc/generic/ implement simple first-fit memory allocator
(modified from original code by Petr Tuma, used under permission)		  
4599 5444 d 9 h decky /trunk/uspace/lib/libc/include/ define just the basic memory allocator interface  
4598 5444 d 9 h decky /trunk/uspace/lib/libc/ remove dlmalloc  
4591 5445 d 9 h decky /trunk/uspace/ add support for creating null devices on demand  
4590 5445 d 15 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 5446 d 3 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 5446 d 5 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4585 5446 d 6 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 5446 d 11 h jermar /trunk/uspace/ Separate the VFS input and output protocols.  
4583 5446 d 13 h svoboda /trunk/uspace/ Fix chaos in block library.  
4572 5448 d 3 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 5456 d 16 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 5457 d 3 h jermar /trunk/uspace/lib/libblock/ Use fibril synchronization in libblock.  
4550 5457 d 4 h jermar /trunk/uspace/lib/libblock/ Disk I/O should be serialized until libblock switches to fibril synchronization.  
4549 5458 d 3 h svoboda /trunk/uspace/ Fix assorted warnings and tiny glitches.  
4542 5459 d 3 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 5459 d 3 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 5460 d 12 h jermar /trunk/uspace/lib/libc/ On condvar signal/broadcast, dequeue the waiting fibril from the waiters list.
Add FIBRIL_CONDVAR_INITIALIZE.		  
4528 5462 d 5 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 5462 d 7 h jermar /trunk/uspace/lib/libc/ Condition variables for fibrils.  
4526 5463 d 4 h jermar /trunk/uspace/lib/libc/ Implement readers-writer locks for fibrils.  
4523 5464 d 6 h decky /trunk/uspace/lib/libc/generic/io/ remove obsolete terminology  
4522 5464 d 6 h decky /trunk/uspace/lib/libc/ remove obsolete comment
cstyle		  
4517 5465 d 3 h jermar /trunk/uspace/lib/libc/ Include fibril synchronization primitives in libc build.  
4516 5465 d 3 h jermar /trunk/uspace/lib/libc/ Add simple synchronization primitives to be used with fibrils.
Provided are mutexes and dummy rwlocks.		  
4514 5465 d 14 h decky /trunk/uspace/lib/libc/ simple implementation of fdopen() and rewind()  
4513 5466 d 5 h jermar /trunk/uspace/lib/libc/generic/ Nit.  
4512 5466 d 5 h decky /trunk/uspace/lib/libc/generic/io/ cstyle  
4511 5466 d 5 h svoboda /trunk/uspace/lib/libc/generic/io/ getchar() and fgetc() are traditionally supposed to flush stdout and stderr.  
4510 5466 d 7 h jermar /trunk/uspace/lib/libc/generic/ A little bit of cleanup and a remedy for great confusion introduced in revision 2483.  
4509 5466 d 11 h decky /trunk/uspace/ rename libadt -> adt  
4508 5466 d 12 h decky /trunk/uspace/lib/libc/ keep a list of open files to support proper cleanup  
4496 5470 d 8 h decky /trunk/uspace/ be more pedantic about undefined function prototypes (to avoid memory access traps)
add missing header files		  
4492 5470 d 15 h jermar /trunk/uspace/ inode_t -> fdi_node_t  
4491 5471 d 2 h decky /trunk/uspace/ rename libc's fs_node_t to inode_t to avoid type conflict with VFS  
4484 5471 d 5 h decky /trunk/uspace/lib/libfs/ add libfs_open_node() helper function
cleanup		  
4483 5471 d 5 h decky /trunk/uspace/lib/libblock/ add missing include
