2569 6208 d 22 h jermar /trunk/uspace/ Tiny refinement of if-else_if-else statement in vfs_register.c.  
2568 6210 d 4 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.
 
2565 6210 d 4 h jermar /trunk/uspace/lib/libc/malloc/ Make uspace malloc() verbose when it aborts due to inconsistencies.  
2564 6210 d 4 h jermar /trunk/uspace/lib/libc/ Support for time() function.  
2550 6214 d 18 h cejka /trunk/ Fixed naming convention in IPC.  
2547 6214 d 21 h cejka /trunk/ Added basic support for device mapper.  
2541 6215 d 22 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.
 
2534 6222 d 18 h jermar /trunk/uspace/ In async_new_connection(), be more robust in the case that the function
is called by the server directly after its client accepts the
IPC_M_CONNECT_TO_ME call.

In fat.c main(), kill the "main" fibril and switch to the connection
fibril.
 
2531 6224 d 15 h jermar /trunk/uspace/ VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.

IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send().
 
2530 6225 d 6 h jermar /trunk/uspace/lib/libc/generic/ Pseudo thread -> fibril change in several comments.  
2529 6225 d 17 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.
 
2528 6225 d 18 h jermar /trunk/uspace/lib/libc/ Modify parts of the build system and libc to support building applications on
paths with differing distances from lib/libc (e.g. uspace/srv/ns and
uspace/srv/fs/fat).
 
2526 6227 d 20 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2525 6227 d 21 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6227 d 21 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().  
2522 6228 d 4 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2520 6229 d 16 h jermar /trunk/uspace/ VFS work.
Turn the dummy skeleton into a dummy skeleton that can handle connections.
There are already traces of the VFS protocol.
 
2495 6292 d 19 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2492 6298 d 17 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2490 6300 d 18 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2489 6300 d 21 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6302 d 13 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6302 d 16 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2485 6306 d 14 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6306 d 15 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6306 d 19 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.
 
2482 6307 d 10 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6307 d 12 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.
 
2479 6311 d 21 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6317 d 15 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6321 d 13 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().
 
2469 6321 d 15 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6321 d 16 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2465 6326 d 20 h jermar /trunk/ Merge arm32 into trunk.  
2445 6333 d 21 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2438 6334 d 14 h decky /trunk/ update for new compiler configuration scheme  
2436 6335 d 15 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
 
2359 6348 d 1 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2230 6386 d 19 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console
 
2229 6386 d 21 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.
