Updater was using this command to find the latest revision modifying a
path:

  git log -1 -- $PATH

but because of git log's history simplificiation [1] when the head of
the branch is a merge commit, the considered revision was not the merge
commit but its parent.

Use --full-history so that git does not simplify history and return the
merge commit if the latest commit is a merge.

I used this blog post

description of the index format.

Using the test class name was causing conflicts on some test classes.
CodingStyleTest was a case, all test use CodingStyleTest class with an
environment variable to control which business template is tested. In
this case, we want one log directory for each business template.

Introduce a getLogDirectoryPath method that's supposed to create and
return the path of the directory to use for log and override this method
for the special case of coding style test.

This test will guarantee that the issue of PyPdf2 overwrite warnings.showwarning method. By default, overwriteWarnings is True in PyPdf2 and we don't want change in many place in ERP5.

Then, this issue should be fixed in PyPdf2 package.

Substitution mapping can be used on the web section default document to include a list of documents.

The documents will match the web section predicates and a category defined on the web section layout configuration parameter.

To benefit from activity deduplication.
This may also improve same-processing-node behaviour when
SQLDict is crowded while SQLQueue is not, making these activities
behaviour more consistent with non-fulltext catalog indexation activities.
