This does not seem to have been a very commonly hit case, since it's
been broken for python3 since before 2014, but a user has just hit it
for the first time.
Fixes#1851873
It is written raw, not via write_template, so it was never added to the
manifest. Therefore, it would remain behind when uninstalling calibre.
Also change the order in which steps are executed, in order to write the
env module -- and add it to the manifest -- before the uninstaller is
created, rather than after (which would be too late).
Some of these files no longer exist due to being devendored.
BeautifulSoup.py is now something else entirely which is
calibre-specific code and deserves the right to be linted.
There is actually no real consequential change here, because the update
is a trivial bugfix that doesn't affect calibre's use, but let's do it
anyway because it is both simple and harmless.
Since installing code will also delete a directory tree, it should run
first. This avoids exotic cases where it deletes the binaries it just
installed.
Use case: co-installing python2/python3 using a bindir bundled with the
rest of calibre's code, in order to maintain an alternatives system
pointing symlinks in /usr/bin at the configured binaries.
In order for xdg-utils programs to successfully install resources to the
staging root instead of /usr, this variable needs to be set and
additionally some arcane directories must be created that xdg-utils,
astoundingly, does not know how to just gracefully handle.
xdg-mime is simply hopeless as it does not have a --noupdate flag. When
using a staged install, copy it with shutil instead.
This creates an additional variable containing the version number
extracted from a git checkout via `git describe`, and diverts all
human-readable output to use that via get_version.
Apparently compileUi explicitly opens the file/buffer as unicode, not
bytes, and then writes a unicode header string (containing the source
file). So the previous attempt to use BytesIO was wrong in this case.
Also images.qrc is being constructed completely in the right here and
now from a bunch of unicode strings, so just use exactly that.
Now replaced in all dynamically loaded code. Recipes/metadata
sources/etc. In the case of recipes, since they get compiled by calibre
we simply make the unicode/unichr names available, no need for any
changes to the actual recipes themselves.
This value can be changed with the following commands:
defaults write -g NSTextInsertionPointBlinkPeriodOff -float 500
defaults write -g NSTextInsertionPointBlinkPeriodOn -float 500
Some mathjax distributions come with the unpacked versions removed as
per the upstream instructions for optimizing an installation. Only use
the unpacked versions if they exist; otherwise fallback on the packed
versions.
Also filter the .woff files to make sure they are actually .woff files,
since they may be files like fonts.dir, fonts.scale, .uuid (created by
xorg-mkfontdir, xorg-mkfontscale, fontconfig).
Improves performance for local clients such as PDF output and the
viewer. Since we have now removed the old unbundled mathjax, the file
count in the resources directory does not go up too much.
If the umask is set up to exlude execute, the installer will set up
calibre to be unreadable by any user other than the installing user.
When installing as `root`, a starting umask of `0o077` results in the
installer choosing a new umask of `0o033`, which means the calibre
install directory (and child directories) are installed with permissions
`0o744`, so only the installing user can actually use the resulting
calibre install.
To test, start with a system umask of `0o077` and run the installer
script as root:
```
% sudo sh ./setup/linux-installer.sh
Using python executable: /usr/bin/python3
WARNING: Your current umask disallows reading of files by some users, this can cause system breakage when running the installer because of bugs in common system utilities.
Should the installer (f)ix the umask, (i)gnore it or (a)bort [f/i/a Default is abort]: f
umask changed to: 022
