word_idx modified should be reset to false for each word index file, or all unchanged word index files after the first changed one will be resaved unnecessarily.
Our config allows to set the values for `dmode` and `fmode` to allow
users to explicitly define which permissions directories and files
should have.
To avoid unnessary chmod operations, we check the current umask to
compare what permissions files and directories would get witout our
intervention. If the result is already what the user wants, no chmods
will happen later on. Otherwise we set new configs called `dperm` and
`fperm` which will be used in chmod ops. This is done in
`init_creationmodes()`
When we created new directories, we used to pass the original `dmode`
config to `mkdir()`. The system will then apply the umask to that
`dmode`.
This means the resulting directory will *always* have different
permissions than `dmode`, *always* requiring a chmod operation.
That's silly.
**Breaking Change:** This patch removes the passing of `dmode` as
second parameter to all `mkdir` calls, making it default to `0700`
which is also what we test against in `init_creationmodes()`.
Plugins not relying on our `io_*` functions and do create their own
directories and which currenlty pass `dmode` to it need to be
adjusted to remove that second parameter.
Users may want to reapply the proper file permissions to their data
folder.
**Revert:** In 9fdcc8fcd8 @movatica
introduced a change to `init_creationmodes()` that compared the umask
against `fmode` instead of `0666`. I merged it because it looked logical
when compared to the code for directories which compared against `dmode`
as described above. However we do not pass `fmode` to any file creation
methods (that's not possible).
The result is that all changes made in the `fmode` setting resulted
in the wrong permissions for newly created files as first reported in
https://forum.dokuwiki.org/d/19463-setting-fmode-not-working-as-intended
I'm unsure about the orginal motivation behind @movatica's change. The
"fix" however, is wrong.
**Tests:** This patch introduces an integration test that will check the
actual results of directory and file creations under various umask,
`dmode` and `fmode` settings.
The $conf['fperm'] value was checked in multiple files using different methods.
This can cause permission trouble with restricted environments, i.e. when chmod is forbidden and file permissions are non-default.
Now, all checks use implicit cast to boolean which leads to consistent behaviour.
Also, a misleading variable was renamed in context to better understand one of the checks.
Not sure why Doku_Indexer caused phpcs to complain about the class name
not being in PascalCase, but Doku_Handler didn't. 🤷
The namespace and new class name was selected to be compatible with the
upcoming changes in #2943. This should hpopefully reduce the overall
hassle of touching the same code base.
