This is maybe not the same problem that Zooko had, but bsddb doesn't build on my Linux 2.4.10 (SuSE 7.3) box either where Sleepycat db-4.1.25 was installed from the sources. It puts db.h under /usr/local/include per default where Python's setup.py doesn't find it. It used to be sufficient for me to add this directory to the db4 incdirs (see patch below) until 2.3c1 -- but this doesn't work for the CVS version any more. And yes, test_time fails with "AssertionError: AEST", too. For 2.3c1 as well as for current CVS.

MacPython-OS9 test failures
by Jack Jansen July 23, 2003

July 23, 2003

Barry (and others), I added a couple of bug reports for things that fail in MacPython-OS9. My personal feeling is that it's best to leave fixing these until the unix/windows/MacOSX release of Python 2.3 has been done. This has the disadvantage that MacPython-OS9 and the rest of the pythons are built from slightly different source trees, but we've done that in the past and no-one seems to be bothered by it. The alternative would be to fix the problems now, with any destabilizing results that may have.

Python Bug 775541 Introduced by Python Patch 769142 as applied. I believe this needs to be fixed for rc2. See Python Patch 776062: http://sourceforge.net/tracker/index.php?func=detail&aid=776062&group_id=54… -- KBK

Test_coercion failing on Panther for complex numbers
by Jack Jansen July 23, 2003

July 23, 2003

I need a little guidance with bug #775892. I think it's non-serious, but I'm not sure (and I don't know how easy it is to fix). Test_coercion is failing on the beta for MacOSX 10.3. All the failures have the same form: the output is (XXX-0j) in stead of the expected (XXX+0j).

optparse 1.4.2 in 2.3: any chance?
by Greg Ward July 23, 2003

July 23, 2003

I'm so out of the loop I didn't even know 2.3c1 was out until I checked www.python.org/2.3 tonight. ;-( Unfortunately, I was really really hoping to get Optik up to version 1.4.2 in time for Python 2.3. The only changes over 1.4.1 are various small refactorings to make Optik/optparse more easily extensible. This should have no effect on people merely using optparse, and anyone extending it (ie. subclassing Option and/or OptionParser) will win -- unless they're extending it by doing evil things like replacing another module's globals. Given that I won't have a minute to work on this stuff until next Monday (July 28) at the earliest, do I have any hope of getting it into 2.3final? Or should I just face reality and make optparse 1.4.2 the first checkin on the 2.3-maint branch? Greg -- Greg Ward <gward(a)python.net> http://www.gerg.ca/ Quick!! Act as if nothing has happened!

PyConfig.h On Solaris
by John Abel July 22, 2003

July 22, 2003

Hi, I apologise if this is an inappropriate post for this list; my query is concerned with the internals of Python, honest :) I am trying to compile a C module on Solaris, to return extended process information (args greater than 80 characters). However, the _FILE_OFFSET_BITS in pyconfig.h is causing me a bit of bother. It is preventing me, from correctly parsing /proc - according to the man pages, any handling of /proc entries must be done with 32bit structures, variables, etc. I've tried undefining it at compile time, without success. I've had to define _LP64, include <procfs.h>, then undefine _LP64. Doing this, allows me to use structured proc, instead of the deprecatd ioctl method. However, I don't think this is a working solution, as the code compiles, runs, but returns dubious results (I have a pure C version of the code, which works fine). I've included the code below. Is there a way, to tell Python to compile a module in 32bit mode? Or, is there a workaround for this Solaris oddity? Regards John #include "Python.h" #include <stdio.h> #define _LP64 #include <procfs.h> #undef _LP64 #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> static PyObject * psinfo_fullpidinfo(PyObject *self, PyObject *args) { PyObject *queryPid; char procBuf[50]; char argStr[512]; char **argvp; int fdPSInfoFile, fdASFile, counter; struct psinfo psBuf; if (!PyArg_ParseTuple(args, "i:pidinfo", &queryPid) ) { return NULL; } (void)sprintf(procBuf,"/proc/%i/psinfo", (int)queryPid); (void)sprintf(asBuf,"/proc/%i/as", (int)queryPid); if ((fdPSInfoFile = open(procBuf, O_RDONLY)) != -1 ) { if (read(fdPSInfoFile, &psBuf, sizeof(struct psinfo)) == sizeof(struct psinfo) ) { close(fdPSInfoFile); if ((fdASFile = open(asBuf, O_RDONLY)) == -1 ) { printf(" Open Of AS Failed"); } else { printf( "%d", psBuf.pr_argc); argvp=(char **) malloc(sizeof(char *) * (psBuf.pr_argc + 1)); if (lseek(fdASFile, psBuf.pr_argv, SEEK_SET) == -1) { printf ("Initial LSeek Failed" ); return NULL; } if (read(fdASFile, argvp, sizeof(char *) * (psBuf.pr_argc + 1)) == -1 ) { printf( "Read Failed" ); return NULL; } for ( counter=0; counter < psBuf.pr_argc; counter++ ) { if (lseek(fdASFile, argvp[ counter ], SEEK_SET) == -1) { printf( "2nd LSeek Failed"); return NULL; } if (read(fdASFile, argStr, 512) == -1) { printf( "Read Of AS File Failed"); return NULL; } printf( "Got %s.\n", argStr ); } close(fdASFile); } } } return Py_BuildValue( "s", argStr ); } static struct PyMethodDef PSInfoMethods[]={ { "fullpidinfo", psinfo_fullpidinfo, METH_VARARGS, "Display Full Arg Details For A Given PID" }, { NULL, NULL, 0, NULL } }; void initpsinfo(void) { (void)Py_InitModule("psinfo", PSInfoMethods); }

Re: [Python-Dev] bsddb3 test hang

I wanted to see this bsddb3 explosion for myself, so I tried to build the module, but couldn't figure out how to do it.

2.3rc1 delayed
by Jeremy Hylton July 22, 2003

July 22, 2003

I've decided to postpone the 2.3 release candidate 1 until Friday. Given the errors reported with current CVS on Cygwin, I don't expect that this release candidate stands much chance of becoming the final release. So I'd rather wait a little and see if anyone can make headway on the Cygwin problems. If we can fix something tomorrow, all the better. If not, we've only lost a day. I also checked in a probable fix for the problem Tim reported when running test_strptime, test_logging, and test_time in that order. I'm not confident that the fix is correct. Basically, it tries to restore the locale to its original value when test_logging finishes. Can someone who understands locales review that change? Please continue to avoid checkins on the head unless the changes are both trivial and critical <0.5 wink>. Jeremy

But as it doesn't, I'd have to agree that it's a new feature and not appropriate at this late stage (much as I'd like it to go in). [Mumble, click] Ah yes.

bsddb3 test hang
by Barry Warsaw July 22, 2003

July 22, 2003

I just did a fresh cvs up, configure, build and am running the test suite with TESTOPTS='-u all -v'. It looks like I'm getting a hang in test_bsddb3 on RH9. Running test_bsddb3 alone works just fine. The hang happens at: test02_SimpleLocks (bsddb.test.test_thread.BTreeSimpleThreaded) ... ok So I don't know if it's this test or the next one. I don't have time at the moment to dig further, but one useful thing would be to see if Martin's last checkin to _bsddb.c has any effect. strace-ing the process gives me: % strace -p 26615 futex(0x82fb8c0, FUTEX_WAIT, 0, NULL -Barry
