* Hi Erik and ManuelEric Andersen2005-01-292-1/+8
| | | | | | | | | | | | | | | | | | Long time no see :) It appears uClibc pthreads native debugging is broken w.r.t thread exit handling in uClibc(at least on PPC). When debugging ex7, gdb(6.2.1) bails out as soon as a thread exits. I found a comment in gdb that TD_DEATH handling was broken for glibc 2.3.1, so I figured that maybe it was broken in uClibc also. I added a #if 0 #endif in pthread_exit( see patch below) and then gdb behaved again. While looking into this I found a few differences( included in the patch) between glibc and uClibc. Don't know if these makes a difference, but I leave that to you to decide. Jocke

| | | | | | | | | | | | | Hi Erik, I'm not sure why the NIOS support is not in uClibc -- perhaps the patch was rejected or never submitted? In any case, I'm playing with some NIOS stuff and created this patch against 0.9.26. The work was done by Microtronix. I'm not sure who else contributed to it. It would be great to have the NIOS support available in uClibc so developers don't have to go searching for these bits. Pete

* Alexandre Oliva writes:Eric Andersen2004-05-141-0/+4
| | | | | | | | | A program that requests __pthread_sig_debug to be blocked will self-deadlock when it requests a thread to be created, because the debugger (rda or gdb) will never get the signal, so it won't wake up the pthread manager as expected. This patch fixes it.

| | | | | | | | | | | | | | | | The vfork() wrapper defined in libpthread, that's used to run pthread_atfork()-registered handlers, is not only a very bad idea, it's broken and useless. Here's the rationale: [---------snip----------] Since the implementation as it stands is broken (linking a program that vfork()s and exec()s on the child and wait()s on the parent works unless you happen to link with libpthread), and I can't think of any workable solution, I suggest that we simply remove the vfork() overrider in the non-MMU case. Yes, we might lose some small amount of functionality here, but it's not like people running uClinux expect anything resembling actual fork() to work.

| | | | | | | | | | | | | | | | | | | | This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem.

These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

* Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III2003-12-273-3/+0
| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.

| | | | | | | | | | | | | This patch adds the libpthread backend bits for sh64. As noted previously, we can't inline things like the testandset() in pt-machine.h as we need to use a completely different ISA / CFLAGS in order for this to work. As a result, this patch is somewhat of a RFC as well to see what people think of the libpthread/linuxthreads/sysdeps Makefile approach, etc. The approach I've taken currently has been to provide a sysdeps/Makefile with a note that TARGET_ARCHs that want build rules can simply add themselves into the list of matching architectures to add to the subdir rule for. This probably isn't the cleanest solution, but it's quite transparent and works quite well.

| | | | | | | | | | | | | | | | | | | | | | I've noticed a few people have posted over the last year about problems compiling programs that use vfork when pthreads are involved. Some detective work turned up that ptfork.c aliases vfork to fork and then tries to call the original fork as __libc_fork. This patch removes the aliasing when there is no MMU present, and uses the same call semantics to call __libc_vfork. I then added a symbol to the m68k vfork.S to allow vfork to be called as __libc_vfork. The same bug exists in the uClibc CVS, and with a possible tweak this patch should go through there as well. Obviously, all other platforms need __libc_vfork as a workable means to call vfork in order for this to work for them. Let me know if there are any problems with this patch.

* Add a new *scanf implementation, includeing the *wscanf functions.Manuel Novoa III2003-08-015-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Should be standards compliant and with several optional features, including support for hexadecimal float notation, locale awareness, glibc-like locale-specific digit grouping with the `'' flag, and positional arg support. I tested it pretty well (finding several bugs in glibc's scanf in the process), but it is brand new so be aware. The *wprintf functions now support floating point output. Also, a couple of bugs were squashed. Finally, %a/%A conversions are now implemented. Implement the glibc xlocale interface for thread-specific locale support. Also add the various *_l(args, locale_t loc_arg) funcs. NOTE!!! setlocale() is NOT threadsafe! NOTE!!! The strto{floating point} conversion functions are now locale aware. The also now support hexadecimal floating point notation. Add the wcsto{floating point} conversion functions. Fix a bug in mktime() related to dst. Note that unlike glibc's mktime, uClibc's version always normalizes the struct tm before attempting to determine the correct dst setting if tm_isdst == -1 on entry. Add a stub version of the libintl functions. (untested) Fixed a known memory leak in setlocale() related to the collation data. Add lots of new config options (which Erik agreed to sort out :-), including finally exposing some of the stripped down stdio configs. Be careful with those though, as they haven't been tested in a long time. (temporary) GOTCHAs... The ctype functions are currently incorrect for 8-bit locales. They will be fixed shortly. The ctype functions are now table-based, resulting in larger staticly linked binaries. I'll be adding an option to use the old approach in the stub locale configuration.
