[Python-Dev] thoughts on having EOFError inherit from EnvironmentError?
http://bugs.python.org/issue1481036 Basically as things are now EOFError is on its own but often wants to be handled the same as other I/O errors that EnvironmentError currently covers. Many uses of EOFError in our code base do not provide it any arguments so it doesn't really fit the (errno, message [, filename]) tuple style that EnvironmentError promises. But we could fudge that with a reasonable default (whats reasonable?) if we rerooted this under EnvironmentError. Alternatively the bug suggests a new parent exception for EnvironmentError and EOFError both to inherit from. Last time changing the heirarchy around this came up there was pushback against adding yet another exception type so I'm thinking the simple re-rooting may be the best answer if anything is done at all. any thoughts? -gps ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

Re: [Python-Dev] Python 2.6a2 execution times with various compilers
I did some more tests concentrating on GCC, partly based on the feedback I got, results at http://www.in-nomine.org/2008/04/12/python-26-compiler-options-results/ Executive summary: Python needs to be compiled with -O2 or -O3. Not doing so, no optimization level, results with GCC 4.2.1 in a doubling of execution time. Using just -O1 is still ~15% slower than using -O2. Using -mtune=native -march=native can shave of 0,1/0,2 seconds, but otherwise I did not find much difference in using having march or mfpmath present.

[Python-Dev] Python 2.4.4/2.4.5 test_pty failure on Solaris 10
I know this is old stuff, but... I want to update our Python 2.4 installation at work from 2.4.2 to 2.4.5 (the latest 2.4 source release). I get a test failure for test_pty, an extra ^M at the end of one line. I don't get a failure in the 2.4.2 installation, but the 2.4.4 and 2.4.5 both fail this test. Looking at the code in test_pty.py, it appears to me that r43570 fixed things for OSF/1 and IRIX which both do weird things with output while breaking things for any other platform by suppressing the \r\n -> \n mapping which used to be performed for all platforms. So, for Solaris, that mapping doesn't happen and the actual and expected outputs don't agree. I'm not suggesting this needs to be fixed, I'm just looking for confirmation of my hypothesis if someone has a moment to compare the two revisions: http://svn.python.org/view/python/branches/release24-maint/Lib/test/test_pty.py?rev=43570&r1=42233&r2=43570 Thanks, Skip ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

I don't know if the # > of args passed are the same in both cases or not. I've now looked into this; in Subversion 1.2, the number of arguments passed to post-revprop-change had changed, giving an addition "action" as $5. This broke the old mailer.py, which expected only 4 arguments. The rationale for this additional argument was to be able to tell whether a property had been added, modified, or deleted; if it was added, the old value was supplied as stdin (since revprops themselves aren't versioned). I've now updated mailer.py, merging our (few) changes into it. If anything seems broken now, please let me know.

There is a long history to that. The short version is that configure decides on its own what flags to pass to the compiler; that overrides any CFLAGS passed by the users. There have been multiple patches over the years to resolve this, eventually arriving at the status quo.

[Python-Dev] weird configure (autotools) setup
Why is CFLAGS in Makefile.pre.in specified as CFLAGS= $(BASECFLAGS) $(OPT) $(EXTRA_CFLAGS) whereas that will negate any CFLAGS you pass to configure? A normal call to configure (as ./configure --help also explains) can contain a CFLAGS specification, e.g.: CFLAGS="-compiler_options" ./configure --config_options Configure happily compiles and tests everything with the working CFLAGS (as evident in config.log), but when it comes to the output substitution it will, of course, not be overridden. Now, I realize that configure.in talks about BASECFLAGS and OPT, but neither of these are documented in the ./configure --help output, nor are they standard when it comes to autotooling. Passing CFLAGS is the defacto standard. Furthermore, when passing compiler options to OPT, these are NOT taken along in the configure tests, which means you might have passed faulty options but configure will not detect any problems with them. You will only encounter this when you start building. So is there any rationale for all this? -- Jeroen Ruigrok van der Werven / asmodai イェルーン ラウフロック ヴァン デル ウェルヴェン http://www.in-nomine.org/ | http://www.rangaku.org/ Contentment that derives from knowing when to be content is eternal contentment... ___ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com

On my 6.3 box it became:

As you can see, some spurious 'thread' mentions got inserted.
Apparently this section is made by makedepend.
