from the commit(s) from issue 633. The diff parser assumed a properly
formatted diff that denotes empty context lines with a single space in
the first column. This single space however was missing, because the
hg and git backends got the diff through PHP's exec() function and
this returns already line-splitted output, but - and this is the actual
problem - removes trailing whitespace at the end of each line, essentially
making " \n" only "\n". When splitting this string now again with
PREG_SPLIT_NO_EMPTY the empty line was completely lost in the diff output.
To make it clear that an empty line does not mark a context line now, but
should stop the diff parsing, the Diff parser now also defaults to 'false'
as line type.
This commit fixes issue 688.
The diff parser code was rewritten for clarity and speed and now handles
a couple of ugly cornercases, like SVN's property change output and single
change chunks, much better. Since the path parsing was unified as well,
the SCM interface gained a new method `getPathStripLevel()` which determines
how many path components need to be shoven off a file name for the SCM
to form a valid path in the workspace (similar to patch(1)'s --strip option).
Fixes issue 627. Automated tests follow.
IDF_FileUtil and change all occurrences accordingly
* cache /etc/mime.types (or whatever is configured) per request in a static
variable in IDF_FileUtil
* always link directly to the download of attached files in the issues view
and place an additional "view" link only for those attachments which we
recognize as text with our weak criteria (closes issue 575)
We now have a limited support of the code review. Still some work to be
done to allow the submission of new patches on a given review and update
the status. For the moment, only pre-commit review is supported.
