[PATCH 1/1] forge: utilities to support classifying patches on the forge
Richard Earnshaw
rearnsha@arm.com
Tue Oct 28 14:10:39 GMT 2025
These two files are intended to be a demonstration of how we could auto-classify
patches submitted to the forge and appropriate labels.
This is work-in-progress; in particular the classify.py code cannot currently
read patch files or look up bugzilla tickets. However, it is possible to run
the script on the output of find (run from the top-level of the gcc source tree)
to see which labels would be added for each file in the repository. Use
something like:
(cd ${gcc_src}; find . \( -name .git -prune \) -o -type f) | ./classify.py
contrib/ChangeLog:
* forge/classify.py: New file.
* forge/labels: New file.

+

+
+# Format of this file:
+# - Comments start with '#' in the first column and continue to the
+# end of a line.
+# - Color markers start with ':color' and indicate the background
+# color of label. The value is RGB in hex. Color directives
+# continue until the next color marker.
+# - Multi-select/exclusive labels are marked ':multi' or ':exclusive'
+# and indicate if the tag forms part of an exclusive set (you can
+# set at most one such label on a patch or issue. These continue
+# until the next multi/exclusive marker. Note the label name's in
+# an exclusive set must follow Forgejo's rules for such labels.
+# - Other lines are in the format:
+# <label-name> {auto-assignment-query} [<optional description>]
+# The description text will be used to populate the description
+# field for the label.
+#
+# The auto-assignment-query is a search term or rule for applying
+# the label to the ticket. No search is performed if the query
+# field is empty ({}).
+#
+# Three forms of query are currently supported:
+# - BZ:<ticket-num>.<field>
+# Extracts 'field' from a bugzilla ticket and uses it to substitute
+# as the last component of the label (all such labels must use the
+# same query and all the valid values for the label must exist.
+# - BZ:imatch(<regex>).<ticket-num>.<field>
+# Extracts 'field' from a bugzilla ticket 'ticket-num'
+
+
+
+## Bug reports
+# All of these labels are expected to be automatically scraped from
+# the primary (first-referenced) bugzilla entry that is identified
+# from the cover text of a patch. Note that they will not be
