revlog: generate trivial deltas against null revision
To avoid extra memory usage and performance issues with large files,
generate a trivial delta header for deltas against the null revision
rather than calling the usual delta generator.
We append the delta header to meta rather than prepending it to data
to avoid a large allocate and copy.
The standalone Windows installer for Mercurial is built in a somewhat
jury-rigged fashion.
It has the following prerequisites, at least as I build it:
Python for Windows
http://www.python.org/ftp/python/2.4.3/python-2.4.3.msi
MinGW
http://www.mingw.org/
Python for Windows Extensions
http://sourceforge.net/projects/pywin32/
mfc71.dll (just download, don't install)
http://starship.python.net/crew/mhammond/win32/
The py2exe distutils extension
http://sourceforge.net/projects/py2exe/
Inno Setup
http://www.jrsoftware.org/isinfo.php
ISTool - optional
http://www.istool.org/default.aspx/
add_path (you need only add_path.exe in the zip file)
http://www.barisione.org/apps.html#add_path
And, of course, Mercurial itself.
Once you have all this installed and built, clone a copy of the
Mercurial repository you want to package, and name the repo
C:\hg\hg-release.
In a shell, build a standalone copy of the hg.exe program:
python setup.py build -c mingw32
python setup.py py2exe -b 1
Note: the previously suggested combined command of "python setup.py build -c
mingw32 py2exe -b 1" doesn't work correctly anymore as it doesn't include the
extensions in the mercurial subdirectory.
If you want to create a file named setup.cfg with the contents:
[build]
compiler=mingw32
you can skip the first build step.
Copy mfc71.dll and add_path.exe into the dist directory that just got created.
If you use ISTool, you open the C:\hg\hg-release\contrib\win32\mercurial.iss
file and type Ctrl-F9 to compile the installer file.
Otherwise you run the Inno Setup compiler. Assuming it's on the path you run:
iscc contrib\win32\mercurial.iss
The actual installer will be in the C:\hg\hg-release\Output directory.
To automate the steps above you may want to create a batchfile based on the
following:
echo [build] > setup.cfg
echo compiler=mingw32 >> setup.cfg
python setup.py py2exe -b 1
iscc contrib\win32\mercurial.iss
and run it from the root of the hg repository (c:\hg\hg-release).
