But what about: "oofoo".strip("foo") => "" "oofoo".strip(["foo", "bar"]) => "oo" I.e., strip could accept *any* sequence (rather than just a string) as its optional parameter, and strip all occurrences of any item in that sequence. More flexible, but I can't think of a good use case, to be honest. <lurk> Cheers, Simon Brunning TriSystems Ltd. sbrunning(a)trisystems.co.uk ----------------------------------------------------------------------- The information in this email is confidential and may be legally privileged.

If people are interested, I can post my little auto-cvs-branch-patch- easier somewhere. It's pretty simple. I run a CVS commit email through it, and it generates a list of commands to run. Seems to work ok now... I also put a NEWS message that specifically mentions the rstrip('L') use case, to make people's life easier.

idle vs. idlefork?

18 Apr '02

Just curious... I noticed a couple idle checkins in the past few days. Are these changes going into idlefork? Is anything flowing back from idlefork to idle? Skip

(Walter: there's no > obligation, and I understand if you prefer not to learn about CVS > branches just yet. :-) I have not problems with branches, but I guess that those that do backports regularily have scripts that simplify the job. What's still missing is the version for unicode. Note that my patch http://www.python.org/sf/424606 works a little different: Here the argument is a complete word that should be stripped, not a collection of characters, i.e. your version: "oofoo".strip("foo") => "" my version: "oofoo".strip("foo") => "oo" -- Walter Dörwald · LivingLogic AG, Bayreuth/Germany · www.livinglogic.de

getter/setter function signatures
by Thomas Heller 18 Apr '02

18 Apr '02

The signature for the getter/setter functions in descrobj.h is typedef PyObject *(*getter)(PyObject *, void *); typedef int (*setter)(PyObject *, PyObject *, void *); At least descrobject.c, cPickle.c and funcobject.c defines PyGetSetDef arrays which use function signatures where the last void* parameter is missing. While obviously this does no harm (so far), it is surely a bug (or am I missing something)? ----- Related: I am always wondering, why the compiler (MSVC 6 in my case) gives a warning when you use these signatures for getter/setter functions PyObject *get(wrapperobject *, void *) int set(wrapperobject *, PyObject *, void *) (warning C4028: formal parameter 1 different from declaration), while if I use these signatures PyObject *get(PyObject *) int set(PyObject *, PyObject *) the compilation gives no warning at all. Another MSVC glitch? Thomas

FROM: GREY KOFI ADMIN.SECRETARY STANDARD SECURITIES. ACCRA, GHANA. DEAR SIR, I do hope this letter will not come to you as a surprise. It was borne out of my desire to share a mutual business relationship with you . My name is GREY KOFI. A 47 years Ghanaian national, married with a wife and four children. I work as an administrative secretary in Standard Securities and Services Limited in Accra-Ghana. I got the information concerning you from the Ghana Chambers of Commerce and Industries after due consultation with my opinion adviser, I decided to contact you believing that by the grace of God, you will accept to be my partner in this business. I joined the services of this company in 1991 as office assistant and have been working with this company for nine years, within this period, I have worked with states and government functionaries who have been using Standard Securities to move huge sums of money U.S Dollars, Pounds Sterling, Foreign Tiakh(Cash)to their foreign partners. They bring in these consignments of money cash and secretly declare the contents as jewelry, Gold, Diamond, Precious stones, Family Treasure, Documents, etc. General Sanni Abacha of Nigeria(dead), Mobutu Sese Sekou of zaire (dead) Foday Sankoh of Sierra Leone,Babangida of Nigeria etc. All these people have hundreds of consignments deposited with Standard securities. Their foreign partners friends and relatives are claiming most of these consignments, but a lot of them are lying here unclaimed for as much as fifteen years. Nobody has ever come for them because in most cases, the documents! of deposits are never available to any body except the depositors but most of them are dead. Some time last year, Standard Security management changed the procedure of claims of consignments. As soon as one is able to supply answers all the test questions as contained in the secret files of any consignment, They consignment will be released to you upon demand from our safe storage. More than one hundred and twenty consignments belonging to Gen.Abacha, and Mobutu have been claimed in the past months. This is why I am soliciting for your co-operation and assistance. Gen. Abacha has 85 consignments deposited with several different names and codes. 35 have been claimed in the past 6 months. Since he died, the first son also died in a plane crash and the second son is facing trial for murderand embezzlement. The family members are under restricted arrest without communication.And can no longer tourch or ask of this consignments as the eyes of their goverment is on them and their consignment with us has overstayed their grace period I have finished every arrangement for you to come and claim consignment NO: 1201 containing US$ 9,000,000.00 and consignment NO: 1200 containing US$ 12,000,000.00. My duty is to supply you with all the information and documents by fax or email which you will use to deal directly with the management. The procedure is simple; You will apply officially to the Director of Operations of Standard Securities for the release of consignments NO; 1200 and NO.1201. They will demand some documents and Secret Codes. Reach me, I will supply you with every detailed information and you will fax it to them. As soon as they confirm it correct, they will invite you for collection. If you do not want to come to Accra, you can arrange with them to transfer the consignment to anywhere but united States of America on agreement. Nobody should ever know that I am involved in this deal except the Lawyer who will write an Agreement for us. I will suggest upon conclusion, 30% goes to you and 70% for me. At the successful completion of the deal, you will arrange for me and family to come over to your country. I am assuring you that this business have been arranged for years now. It is very secure and risk free. Reach me on kofigrey(a)yahoo.com for further explanation and directives on the procedure, God bless you. Yours Sincerely, GREY KOFI Get back to me via:kofigrey@yahoo.com

string.strip and friends for 2.2.2...
by Anthony Baxter 18 Apr '02

18 Apr '02

I'd like to add the optional argument support for strip and friends to 2.2.2. It solves a real problem, and is useful for people going forward (in the same way as the not-really-bool() code).

core out of select.so
by Geoff Gerrietts 17 Apr '02

17 Apr '02

I'm currently able to pretty reliably produce a core file using Zope 2.5.0 and Python 2.1.3 on a box based on RedHat 6.2. The core is produced due to a segfault, from in select.so. I can look at the backtrace, and I've done some preliminary inspection of the active code object, the call out to select.so, etc. I haven't learned much as a consequence of that, unfortunately: the args passed to the C function don't appear to be a valid python object (can't access the type object), though the function seems okay; and I don't appear to have a filename for my code object (just /). My backtraces appear to vary in quality (not sure why) -- sometimes I get all the symbols I expect, sometimes I get no symbols at all. The best traceback I have at the moment (though I I'm writing now in the hopes that some of the regulars here have some standard recipes for extracting useful information from the backtraces that I might get something approaching a reconstruction of the python code that's being executed, and the arguments that are being supplied. If nobody's got any hints, that's fine, I'm still working on it -- but if you do, I'd appreciate it.

Importing top-level modules
by j.her＠t-online.de 17 Apr '02

17 Apr '02

Hi! I had a problem yesterday where I wanted to extend a top-level module by a module in a subpackage. I naively named my module the same as the toplevel module, and peer import bit me. I finally had to rename my module for no good reason to get things working. So my question is: is there an easy way to force a top-level import (adress the top-level namespace), that I overlooked? If not, what do you think of a from __top__ import systemmodule similar to from __future__ ... An alternative syntax would be "import .systemmodule", but that seems obscure. Ciao, Jürgen
