I'm hoping someone can provide me with some more advanced examples or
assistance regarding the use of PyInstaller's PYZ Archives and approaches
for reducing redundancy in minimal deployments. I started with the
following simplistic .spec file for onefile:
# -*- mode: python -*-
a = Analysis(['j:\\rpmv\\RPM UI - V2\\src\\bootstrap.py'],
pathex=['j:\\git\\pyinstaller'],
hiddenimports=[],
hookspath=None,
runtime_hooks=None)
pyz = PYZ(a.pure)
exe = EXE(pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas - [('.\\pywintypes27.dll', '', '')],
name=os.path.join('dist', 'rpmgui.exe'),
debug=False,
strip=None,
upx=True,
console=False , icon='j:\\rpmv\\rpm UI -
v2\\src\\icons\\rpm-32.ico')
app = BUNDLE(exe,
name=os.path.join('dist', 'rpmgui.exe.app'))
And that seems to work, but single-file is less than optimal for my
scenario - I've got 7 or 8 scripts that share resources, so I started
working on a combined .spec file. It contains several Analyses, then I
create a combined PYZ for all of them:
# Create a common zip file.
Archive = PYZ(UIW.pure + LPR.pure + RAW.pure + EML.pure + DBM.pure +
PDF.pure,
'common.bin')
# Attempt to create our first output file.
UIW_EX = EXE(UIW.pure - Archive.toc,
UIW.scripts,
UIW.binaries,
name = 'rpmgui.exe',
console = True)
output = COLLECT(UIW_EX,
Archive,
name = 'dist-combo')
And that produces an output directory for me that contains this:
02/01/2013 01:03 PM <DIR> .
02/01/2013 01:03 PM <DIR> ..
02/01/2013 11:23 AM 3,638,842 common.bin
01/29/2013 01:36 PM 11,829 pyi_archive
01/29/2013 01:36 PM 7,322 pyi_importers
01/29/2013 01:36 PM 2,254 pyi_os_path
02/01/2013 01:03 PM 193,461 rpmgui.exe
02/01/2013 01:03 PM 967 rpmgui.exe.manifest
11/05/2012 07:56 AM 234 struct
7 File(s) 3,854,909 bytes
2 Dir(s) 327,856,742,400 bytes free
So I feel like I'm getting close to what I want, but my output directory
doesn't contain python27.dll and I was wondering if there was any example
code for the "top level code" that would allow these programs to load
directly from the PYZ. Is that something as simple as this:
sys.path.append(<path to zip file>)
Or is there something else I need to do to massage my apps into finding
their modules in this zip file? Ideally, I'm trying to get to a point
where I deploy as few files as possible (the PYZ, python27.dll, and the
.exe files is all I'd like, but I'll take other files if absolutely
necessary) and get things running so that it doesn't have to extract the
contents of the PYZ. Some of the programs are launched repeatedly in rapid
succession - the extra disk overhead of extracting, reading, operating, and
cleanup is degrading performance for us.
Thanks in advance for any suggestions. Please let me know if I can provide
more information.
