This closes SF bug #446136.
Fixed description of RE modifiers so that RE{#} and RE{#,} are more
clearly described and disambiguated (plain RE{#} had not been described
at all). Reported by Jeremy Craven via email.
delete the Tools and Lib directories at uninstall time. However,
under the old version of Wise, they didn't actually do anything. Under
the new version, they work as advertised, and even delete files users
added.
Got rid of those, and replaced them with similar uninstall cmds that
get rid of all .pyc and .pyo files (whether or not the installer created
them). This works nicely! It still tears down the directory structure,
except for those directories needed to get to any non-.pyc/o file(s) the
user may have added.
turns out the canned new "backup directory" dialog put its "back" and
"next" buttons at a different relative horizontal position than all the
other canned dialogs. This explains why you had to keep moving the
mouse around if you wanted to do a straight all-default install -- the
Next button kept moving around. Now the back/next buttons are in exactly
the same place on all dialogs, and you can click straight thru to the end.
about installing into a pre-existing directory *unless* you hit the
Browse button first. At least while testing, this screwed me repeatedly.
Plus I really liked the Inno Setup scheme of giving you a list box in
its "select directory" dialog without needing a distinct browse button
to ask for that.
So I redid this dialog from scratch: now gives a list box at once, the
browse button is gone, it asks for confirmation if the directory already
exists, and, since this is the first dialog in the set now, also removed
its "Back" button.
Python warning which can be catched by means of the Python warning
framework.
It also adds two new APIs which hopefully make it easier for Python
to switch to buffer overflow safe [v]snprintf() APIs for error
reporting et al. The two new APIs are PyOS_snprintf() and
PyOS_vsnprintf() and work just like the standard ones in many
C libs. On platforms which have snprintf(), the native APIs are used,
on all other an emulation with snprintf() tries to do its best.
GUI inserting those once before shortly after I started using it, but
don't know what triggers it -- presumably something in the "expert" view
(which is, suitably enough, unsuited to experts <wink>).
plain unprivileged User acct:
+ Had to duplicate Wise's Uninstal.wse script, in order to change the line
at its end that unconditionally tries to write uninstall info under HKLM.
This is our new file Uninstal.wse, which must be included by python20.wse
instead of using Wise's version.
+ In every other case we write to HKLM, also write to HKCU instead (we
were already doing that in *most* places, but not quite all).
+ If the user doesn't have admin privs, the DLLs we usually write to the
system dir are written to the root of the Python installation instead.
That's python22.dll, plus the two MSVC runtime DLLs.
+ Added a new component "Register file extensions". Registering .py etc
is done under HKEY_CLASSES_ROOT, and that also requires admin privs;
i.e., AFAICT it's impossible for an unprivileged user to accomplish this.
In the component selection dialog, if the user doesn't have admin privs
I gray out this new component so the user knows they aren't getting file
extensions.
After all that, Python installs, the Start Menu entries are OK, it runs
its test suite to completion, and the uninstaller works too. Only known
problem so far is that the integration with Win2K's Add/Remove subsystem
isn't quite right yet in this irritating case.
