ISSUES
1. [New comment] hashlib update really slow
http://ironpython.codeplex.com/workitem/34022
User clayton123 has commented on the issue:
"<p>This is probably only part of the problem, but the modules I've tried in
hashlib (md5, sha256, and sha512) all seem to have a strange linear increase in
how long it takes to call update(). Try this test code:<br>```<br>import
hashlib<br>from time import clock</p><p>buffer = ' '*1024<br>hash_count =
10000<br>hasher = hashlib.md5()<br>output = open( 'linear_growth.txt', 'wt'
)<br>while hash_count > 0:<br> start = clock()<br> hasher.update(
buffer )<br> finish = clock() - start<br> print >> output,
finish<br> hash_count -= 1<br>output.close()<br>```<br>When I run this on my
machine (64 bit Windows Server 2008 with IronPython 2.7.3) and look at the
timing data there is a very clear linear growth that suggests each call to
update takes (on average) around 3.5 usec longer than the one before. The
graphs are different between ipy and ipy64, but the growth trend is the same.
Very strange.</p"-----------------
2. [New comment] hashlib update really slow
http://ironpython.codeplex.com/workitem/34022
User pingy has commented on the issue:
"<p>Clayton123</p><p>thanks for the test code. Indeed I can reproduce the
linear growth phenomenon. The plot of the time per update vs iteration number
looks like an escalator. In fact, one can see detect multiple trend lines all
with the same slope. Very weird.</p"-----------------
3. [New comment] ast.parse fails on semicolon
http://ironpython.codeplex.com/workitem/34196
User paweljasinski has commented on the issue:
"<p>I think you have to update to 2.7.4 beta 1. Here is what I am
getting:</p><p>C:\Program Files\Console2>ipy<br>IronPython 2.7.4a1
(2.7.0.40) on .NET 4.0.30319.296 (32-bit)<br>Type "help",
"copyright", "credits" or "license" for more
information.<br>>>> import ast<br>>>> m=ast.parse("a =
1;b = 2")<br>>>>

know how to edit my own posts </p"-----------------
5. [New issue] Can't install 2.6.2 for .Net 4.0 - can't find wininst-9.0.exe
http://ironpython.codeplex.com/workitem/34199
User smartjoel has proposed the issue:
"I need to install 2.6 because i need to run Ironclad.
I am installing on Windows7 (x64).
The failing happens here:
InstallFiles: File: wininst-9.0.exe, Directory: C:\Program Files
(x86)\IronPython 2.6 for .NET 4.0\Lib\distutils\command\, Size: 196096
Error 1334. The file 'File_wininst_9.0.exe' cannot be installed because the
file cannot be found in cabinet file 'IronPy.cab'. This could indicate a
network error, an error reading from the CD-ROM, or a problem with this package.
MSI (s) (BC:0C) [09:34:33:380]: Product: IronPython 2.6 for .NET 4.0 -- Error
1334. The file 'File_wininst_9.0.exe' cannot be installed because the file
cannot be found in cabinet file 'IronPy.cab'. This could indicate a network

package."-----------------
6. [New comment] Can't install 2.6.2 for .Net 4.0 - can't find wininst-9.0.exe

User smartjoel has commented on the issue:
"<p>I wonder why it is File_wininst_9.0.exe? why 'File_ ' is appended to
wininst9.0.exe?</p"
