See http://www.nuttx.org/doku.php?id=wiki:graphics:nxgraphics - for a description of the fat, flat line bug. - * libc: Renamed nuttx/lib to nuttx/libc to make space for a true lib/ - directory that will be forthcoming. Also rename libraries: liblib.a -> libc.a, - libulib.a -> libuc.a, libklib.a -> libkc.a, liblibxx.a ->libcxx.a. - (I will probably, eventually rename libxx to libcxx for consistency) - * Makefile, lib/: A new, empty directory that will hold generated libraries. - This simplifies the library patch calculations and lets me get rid of some - bash logic. The change is functional, but only partially complete; - additional logic is needed in the arch/*/src/Makefile's as well. Right - now that logic generate multiple library paths, all pointing to the lib/ - directory. - * arch/*/src/Makefile: Now uses only the libraries in lib/ - Replace bash fragments that test for board/Makefile. - * Makefile.win: The beginnings of a Windows-native build. This is just - the beginning and not yet ready for prime time use. - * configs/stm32f4discovery/winbuild: This is a version of the standard - NuttX OS test, but configured to build natively on Windows. Its only - real purpose is to very the native Windows build logic. - * tools/mkdeps.bat and tools/mkdeps.c: mkdeps.bat is a failed attempt - to leverage mkdeps.sh to CMD.exe.

Provided - by Konstantin Dimitrov. - * Fixed an uninitialized variable in the file system that can cause - assertions if DEBUG on (contributed by Lorenz Meier). - * Config.mk: Defined DELIM to be either / or \, depending upon - CONFIG_WINDOWS_NATIVE.

From Petteri Aimonen. - * graphics/nxtk/nxtk_getwindow.c: Clipping would change the offset of returned - data, and caller has no way to know what the new offset would be. This messes - up font drawing when the text is partially out of window, e.g. when scrolling. - Also from Petteri Aimonen. - * include/stdbool.h: Can now be disabled for C++ files if CONFIG_C99_BOOL8 is - defined. CONFIG_C99_BOOL8 indicates (1) that the sizeof(_Bool) is one in both - C and C++, and (2) the the C compiler is C99 and supports the _Bool intrinsic - type.

Needed to move the + releasing of a semaphore inside of some conditional logic + (cosmetic). + * include/nuttx/sched.h, sched/task_setup.c, and sched/task_exithook.c: + Add support for remembering the parent task and sending + SIGCHLD to the parent when the task exists. + * sched/task_exithook.c: Fixed a *critical* bug. Here is + the scenario: (1) sched_lock() is called increments the lockcount + on the current TCB (i.e., the one at the head of the ready to run + list), (2) sched_mergepending is called which may change the task + at the head of the ready-to-run list, then (3) sched_unlock() is called + which decrements the lockcount on the wrong TCB. The failure case + that I saw was that pre-emption got disabled in the IDLE thread, + locking up the whole system. + * sched/sched_waitpid.c: Use SIGCHLD instead of a semaphore. This + is a much more spec-compliant implementation. However, there are + some issues with overruning signals because NuttX does not support + queueing of signals (POSIX does not require it).

This caused lots of problems + when changing configurations because there is no easy way to get the + system to rebuild the context. Now, the context will be rebuilt + whenever there is a change in either .config or the Makefile. + * apps/builtin/registry: Updated new built-in registration logic to handle + cases where (1) old apps/.config is used, and (2) applications ared + removed, not just added. + * apps/examples/nettest/Makefile: Fix an error that crept in during + some of the recent, massive build system changes. + * apps/builtin/Makefile: Need to have auto-generated header files + in place early in the dependency generation phase to avoid warnings. + It is not important if they are only stubbed out header files at + this build phase. + * apps/examples/hidbkd: Now supports decoding of encoded special keys + if CONFIG_EXAMPLES_HIDKBD_ENCODED is defined. + * apps/examples/hidbkd: Add support for decoding key release events + as well. However, the USB HID keyboard drier has not yet been + updated to detect key release events. That is kind of tricky in + the USB HID keyboard report data. + * apps/examples/wlan: Remove non-functional example. + * apps/examples/ostest/vfork.c: Added a test of vfork(). + * apps/exampes/posix_spawn: Added a test of posix_spawn(). + * apps/examples/ostest: Extend signal handler test to catch + death-of-child signals (SIGCHLD). + * apps/examples/ostest/waitpid.c: Add a test for waitpid(), waitid(), + and wait(). + * builtin/binfs.c: Add hooks for dup() method (not implemented). + * builtin/exec_builtin.c, nshlib/nsh_parse.c, and nshlib/nsh_builtin.c: + NSH now supports re-direction of I/O to files (but still not from). + * builtin/binfs.c: Greatly simplified (it is going to need to be + very lightweight). Now supports open, close, and a new ioctl to recover + the builtin filename. The latter will be needed to support a binfs + binfmt. + * builtin/binfs.c: Move apps/builtin/binfs.c to fs/binfs/fs_binfs.c + CONFIG_APPS_BINDIR rename CONFIG_FS_BINFS + * apps/include/builtin.h: Some of the content of + apps/include/apps.h moved to include/nuttx/binfmt/builtin.h. + apps/include/apps.h renamed builtin.h + * apps/builtin/exec_builtins.c: Move builtin + utility functions from apps/builtin/exec_builtins.c to + binfmt/libbuiltin/libbuiltin_utils.c + * apps/nshlib/nsh_mountcmds.c: The block driver/source + argument is now optional. Many files systems do not need + a source and it is really stupid to have to enter a bogus + source parameter. + * apps/nshlib/nsh_fileapp.c: Add the ability to execute a file + from a file system using posix_spawn(). + * apps/builtin/: Extensions from Mike Smith. + * apps/examples/ftpd/Makefile: Name ftpd_start is not the name of + the entrypoint.

It draws in + wrong place, and doesnt look very good in the correct place either. (from Petteri Aimonen). - * NxWidgets::CScrollingPanel: Usability improvements. It is borderless for now, - because there was no easy way to redraw only the required part of the border. - Contributed by Petteri Aimonen. - * NxWidgets::CNxWidgets and NxWM::CStartWindow: Small changes to make sub- - classing easier (from Petteri Aimonen). + * NxWidgets::CGraphicsPort: Many times we only want a constant background. + In that case the old code fills the background, reads it back, renders + the text and then writes it back. When used with LCD's (instead of + framebuffers) this causes unnecessary delay and screen flicker. + This commit adds a variant of drawText that takes background color, + so that the background and text can both be rendered at one go. + The old functions still function as before (Petteri Aimonen). + * NxWidgets::CLabel: The label was drawn as a single rectangular region, + then a text was added to the on top of this. The result is that the + text would flicker when the CLabel was updated. With this change, the + two step update is replaced with a five step update: The background + is updated as four rectangulear regions (leaving the previous text in + place), then the new text is updated. This eliminates the flicker + (Petteri Aimonen). + * Kconfig: Many NxWidgets/NxWM settings do not have meaningful, generic + default values. Colors, for example, depend on pixel depth. Some + geometry settings depending on other geometry settings. Font IDs are + not know-able by the configuration system. etc. In these cases, it + is best if the settings are just not undefined so that the system can + calculate a reasonable default. however, if no default is provided + in the .config file, mconf will complain and generate errors. So work + around this, I added several "enabling" settings to override the + default setting. This is awkward and I preferred the configuration as + it was before, but this avoids the mconf errors and warnings. + * UnitTests: Changed occurrences of lib_rawprintf() and lib_lowprintf() + to match recent changes to NuttX (will be in NuttX-6.25) + * CGraphicsPort::_drawText: Renamed from CGraphicsPort::drawText in order + to eliminate some naming collisions when overloaded in some configurations + (i.e., when both bool and nx_pixel_t are uint8_t). From Petteri Aimonen. + * CNxWidgets::drawContents: Change base drawContents from a do-nothing + function to a function that fills the widget with the background color. + This is useful when using CNxWidgets as a "panel" , i.e. a container + for other widgets. Subclasses will override drawContents and decide + themselves how to draw the background. + * CNxWidgets::CTabPanel: A new widget contributed by Petteri Aimonen. + This widget provides a tab panel, which has a button bar at the top + and panels below it. Pressing a button will select the corresponding + panel. uClibc++-1.0 2011-11-05 <gnutt@nuttx.org> diff --git a/nuttx/ReleaseNotes b/nuttx/ReleaseNotes index 02cb8158d..9d146e90a 100644 --- a/nuttx/ReleaseNotes +++ b/nuttx/ReleaseNotes @@ -3440,3 +3440,323 @@ Bugfixes (see the change log for details).

In NuttX-6.25, this interface is + available only for ARM7/9, ARMv7-M (Cortext-M3/4), and MIPS32 + (PIC32MX) platforms. + - exec() now sets the priority of the new task to the same priority as + the parent task (instead of the arbirtrary value of 50). + - New, partially complient implementations of execv() and execl(). + These are only partially compliant because they do not overlay any + existing "process space" but rather create the new task and exit(). + - Add a complete implementation of posix_spawn(). This standard + interface is a better match for an MMU-less architecture than are + vfork() plus execv() or execl(). + - Add a task start hook that will be called before the task main + is started. This can be used, for example, to schedule C++ + static constructors to run automatically in the context of the + new task. + + * Task Parentage + + - Repartitioned tasking data structures. All shared resources are now + collected together in a "task group". A task group includes the + original task plus all of the pthreads created by the task. + - Added support for remember the parent "task group" when a new task is + started. + - Added optional support to record the membership of each thread in + the "task group". + - Implement support for retaining child task status in the "task group" + after the child task exists. This is behavior required by POSIX. + But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and + CONFIG_SCHED_CHILD_STATUS + - Add internal logic to "reparent" a task. This is useful, + for example, where the child task is created through a trampoline + task that redirects I/O. Reparenting allows the caller of posix_spawn() + to be reparented for the eventual child thread. + - Added support for SIGCHLD. Sent to all members of the parent task + group when the file member of the child task group exits. + - If SIGCHLD and retention of child task exist status are enabled, then + a more spec-compliant version of waitpid() is enabled. + - New interfaces waitid() and wait() are also enabled when SIGCHLD + is enabled. + + * File System + + - dup() and dup2() can new be used with opened files in a mounted file + system. This supports re-direction of output in NSH to files. + - The binfs file system was moved from apps/builtin to fs/binfs. The + binfs file system was extended to support execution of "builtin + applications" using exec(), execv(), execl(), or posix_spawn(). + - Added logic based on SIGCHLD to automatically unload and clean-up + after running a task that was loaded into memory. + + * Binary Formats + + - Much of the logic for "builtin applications" was moved from + apps/builtin to nuttx/binfmt/libbuiltin. Includes some extensions + contributed by Mike Smith. + - A binary loader was added for builtin applications to support + execution of "builtin applications" using exec(), execv(), + execl(), or posix_spawn(). + + * Drivers: + + - Added logic to marshal and serialized "out-of-band" keyboard + commands (such as cursor controls and key release events) intermixed + with normal ASCII keypress data. The encoding is partially integrated + in the HID keyboard driver and the decoding full integrated into the + apps/examples hidkbd and keypadtest (the latter contributed by Denis + Carlikli). + - Driver for the UG-2864HSWEG01 OLED contributed by Darcy Gong. + - Add support for removable serial devices (like USB serial). This + support is enabled by CONFIG_SERIAL_REMOVABLE. + + * ARMv7-M: + + - Added an option to use the BASEPRI register to disable interrupts + (instead of the PRIMASK). This eliminates some innocuous hardfaults + that interfere with some debug tools. You need to switch to the + BASEPRI method only if you have such tool interference. + + * STM32 Drivers + + - Bring STM32 F1 DMA capabilities up to par with the STM32 F2/F4 + (contributed by Mike Smith). + - Add support for USART single wire mode (Contributed by the PX4 + team). + - Updates to support for SPI DMA on the STM32 F1/F2/F4. From + Petteri Aimonen. + + * STM32 Boards: + + - New configuration to support the UG-2864HSWEG01 OLED on the + STM32F4Discovery board. + - Added a posix_spawn() test configuration for the STM32F4Discovery. + + * LM3S/LM4F + + - Files and directories repartitioned to support both LM3S and LM4F + using the STM32 organization as a model. + - Partial definitions for the LM4F contributed by Jose Pablo Carballo + (this is still a work in progress). + + * LM3S Boards + + - Added scripts and documentation to use OpenOCD with the LM3S (from + Jose Pablo Carballo). + + * LPC176x/LPC178x + + - Files and directories repartitioned to support both LPC175x/LPC176x + and the LPC177x/LPC178x families using the STM32 organization as a + model. The LPC1788 port is a work in progress by Rommel Marcelo. + + * LPC176x/LPC178x Boards: + + - Added a configuration to support the Wave Share Open1788 board. + This is still a work in progress by Rommel Marcelo. + + * LPC2148 Boards: + + - Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148 + and the UG_2864AMBAG01 OLED). + - Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148 + and the UG_2864AMBAG01). + + * Simulator: + + - Add an nxlines configuration for the simulator. + + * Networking: + + - Add logic to work around delayed ACKs by splitting packets + (contributed by Yan T.). + - Split net_poll() to create the internal interface psock_poll(). + + * LCDs: + + - Added support for LCD1602 alphanumeric LCD (HD4468OU controller). + + * Graphics: + + - Added 5x8 monospace font. This tiny font is useful for graph + labels and for small bitmapped display. Contributed by Petteri + Aimonen. + + * Build System: + + - Add an options to better manage toolchain prefixes. + - Redesigned how the context targer works in the apps/ directory. + The old design caused lots of problems when changing configurations + because there is no easy way to get the system to rebuild the + context. This change should solve most the problems and eliminate + questions like "Why don't I see my builtin application in NSH?" + + * Kconfig Files: + + - There are several new configurations that use the kconfig-frontends + tools and several older configurations that have been converted to + use these tools. There is still a long way to go before the conversion + is complete: + + configs/sim/nxwm + configs/sim/nsh + configs/stm3220g-eval/nxwm + configs/stm32f4discovery/posix_spawn + configs/olimex-lpc1766stk/nsh + configs/olimex-lpc1766stk/hidkbd + configs/olimex-lpc1766stk/nettest + configs/open1788/ostest + configs/stm32f4discovery/nsh + configs/stm32f4discovery/usbnsh + configs/lm326965-ek (all configurations) + configs/mcu123-214x/nsh + configs/ubw32/ostest + + * Tools: + + - tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell. + - tools/configure.c: configure.c can be used to build a work-alike + program as a replacement for configure.sh. This work-alike + program would be used in environments that do not support Bash + scripting (such as the Windows native environment). + - tools/configure.bat: configure.bat is a small Windows batch + file that can be used as a replacement for configure.sh in a + Windows native environment. configure.bat is actually just a + thin layer that executes configure.exe if it is available. If + configure.exe is not available, then configure.bat will attempt + to build it first. + + * Applications: + + - New and modified examples: + + apps/examples/wlan: Remove non-functional example. + apps/examples/ostest: Added a test of vfork(). Extend signal + handler test to catch death-of-child signals (SIGCHLD). Add a + test for waitpid(), waitid(), and wait(). + apps/exampes/posix_spawn: Added a test of posix_spawn(). + + - NSH: + + NSH now supports re-direction of I/O to files (but still not from). + The block driver source argument to the mount command is now + optional for file systems that do not require a block driver. + NSH can now execute a program from a file system using posix_spawn(). + Added support for a login script. The init.d/rcS script will be + executed once when NSH starts; the .nshrc script will be executed + for each session: Once for serial, once for each USB connection, + once for each Telnet session. + + - Supports a new daemon that can be used to monitor USB trace outpout. + - Removed non-functional wlan example. + +Bugfixes (see the ChangeLog for details). Some of these are very important: + + * Tasking: + + - Fixed a *critical* task exit bug. Here is the failure scenario: + (1) sched_lock() is called increments the lockcount on the current + TCB (i.e., the one at the head of the ready to run list), (2) + sched_mergepending is called which may change the task at the head + of the ready-to-run list, then (3) sched_unlock() is called which + decrements the lockcount on the wrong TCB. The failure case that + I saw was that pre-emption got disabled in the IDLE thread, locking + up the whole system. + + * Signals: + + - sigtimedwait() would return a bad signal number if the signal was + already pending when the function was called. + + * Drivers: + + - Some SD cards will appear busy until switched to SPI mode for + first time. Having a pull-up resistor on MISO may avoid this + problem, but this fix from Petteri Aimonen makes it work also + without pull-up. + + * STM32 Drivers: + + - STM32 FLASH driver counting error (from Freddie Chopin). + - STM32 F4 maximum SPI frequency was wrong (corrected by Petteri + Aimonen). + + * STM32 Boards + + - Due to cloning of untested code, the logic to control on-board + LEDs did not work on any STM32 boards. + - Serial devices number /dev/ttyS0-5 is there is a serial console, + but /dev/ttyS1-6 if there is no serial console. + + * Binary Formats + + - C++ static constructors execute now using a start taskhook + so that they execute in the context of the child task (instead + of in the context of the parent task). + + * File Systems: + + - Several FAT-related bugs fixed by Petteri Aimonen. + + * Networking: + + - Fix poll/select issure reported by Qiang: poll_interrupt() must call + net_lostconnection() when a loss of connection is reported. Otherwise, + the system will not remember that the connection has been lost and will + hang waiting on a unconnected socket later. + - Similar issues corrected for recvfrom() and send(). + - Telnetd would hang in a loop if recv() ever returned a value <= 0. + + * Libraries: + + - fread() could hang on certain error conditions. + - Can't handle SYSLOG output to a character device from the IDLE task + (because the IDLE task can't block). + + * Build System: + + - Serial was driver was not being built if there is no console + device. Obviously, the serial driver may be needed even in + this case. + + * Additional Bugfixes: + + - sig_timedwait() and clock_time2ticks.c: Timing "rounding" logic + - ARM9 Compilation issue with low vectors. + - readline() return value + - Others as detailed in the ChangeLog: HID keyboard, LPC17xx bit + definitions, strndup(), PL2303, SYSLOG error handling, AT25, + apps/examples. |
