Mailing List Archive: ANN: Gadfly bugfix test release

Gadfly users and others: Please try one of the following
files

http://www.chordate.com/kwParsing/kwPtest.tgz (tar/gz version)

or

http://www.chordate.com/kwParsing/kwPtest.zip (zip version)

I believe this replacement fixes the following longstanding bugs:

-- multiline strings should be supported by sql parser.
-- table creates should not require a commit before inserts work.
-- unique indices should raise exception on non-unique insert.
-- table create followed by a recreate shouldn't require a commit to
work.
-- an obscure recovery error which is hard to describe
-- a server bug having to do with not handling poorly formed
requests correctly.

Also, the *.zip file has the correct version of gfclient.py unlike the
current one.
Also http://www.chordate.com/gfcontrib.html has the correct gfplus.py
link now.

Pleasy anyone try these replacements. The test suite

http://www.chordate.com/kwParsing/indexbug.py

demos that some of these bugs have been fixed (it will fail in several
ways with the current version).

If I don't hear complaints I will make this gadfly 1.01 in a week or so.
The changes are mainly very small ones. The big ones aren't ready for
prime time yet.

I just uploaded these *again*. One new bug is fixed
[recovery problem that is impossible, that someone ran
into anyway] and an old bug that wasn't actually fixed
before [unique indices should correctly prevent non-unique
inserts] is now fixed, I think.

Please try it out. I'll make it the official release
after it's stable. Thanks for previous feedback!!

Two more comments:
1) I just decided to go to the O'Reilly Open Source
Conference: does anyone want a hotel roommate?

2) In my efforts for gadfly 2 I came up with the following
benchmark

def test():
range1 = range(100, 30000)
print "testing loop"
from time import time
now = time()
result = range1[:]
for i in range(len(range1)):
result[i] = (range1[i], 'x')
elapsed = time()-now
print "elapsed", elapsed
print;
print "testing map"
now = time()
result = map(None, range1, ['x']*len(range1))
elapsed = time()-now
print "elapsed", elapsed

def test2():
range1 = range(100, 30000)
print "testing loop"
from time import time
now = time()
result = range1[:]
for i in range(len(range1)):
result[i] = range1[i]-3
elapsed = time()-now
print "elapsed", elapsed
print;
print "testing map"
now = time()
from operator import sub
result = map(sub, range1, [3]*len(range1))
elapsed = time()-now
print "elapsed", elapsed

test()
print
test2()

On my underpowered win95 machine this prints
testing loop
elapsed 1.10000002384

testing map
elapsed 0.330000042915

testing loop
elapsed 0.439999938011

testing map
elapsed 0.330000042915

Does this mean that map is always better than for
loops even when it looks stupid? Inquiring minds
want to know.
