releasenotes: make the import of fuzzywuzzy optional If fuzzywuzzy is note present, we will not be having the capability to merge existing releasenotes with the new releasenotes on the similarity basis. The merging will still work good for exact same releasenotes entries. Differential Revision: https://phab.mercurial-scm.org/D1096

webcommands: replace str(ctx) etc with pycompat.bytestr(ctx) etc hgweb can now serve the graph view in Python 3. Differential Revision: https://phab.mercurial-scm.org/D1138

templater: don't blow up when trying to build an abort message __name__ is unicode, but we need bytes. For now, we'll make the (mostly-safe) assumption that template filter names will be ascii. Differential Revision: https://phab.mercurial-scm.org/D1137

webutil: use pycompat.bytestr() instead of str() Stops us from choking the templater on Python 3. With this patch applied, much of hgweb works correctly in Python 3. The notable exception is the graph page, which chokes because it gets node IDs as str instead of bytes. Differential Revision: https://phab.mercurial-scm.org/D1135

hgweb: correct an earlier error of mine - `start` should be bytes Gets hgweb very close to working with Python 3. Differential Revision: https://phab.mercurial-scm.org/D1134

config: simplify aliasing commands.update.check experimental.updatecheck was renamed into commands.update.check, use the config system to provides the fallback on the old config name instead of adding more code. Differential Revision: https://phab.mercurial-scm.org/D1117

run-tests: set HGPLAIN=1 when bisecting Otherwise a customized template may break the regex matching the bisect output. Differential Revision: https://phab.mercurial-scm.org/D949

run-tests: extract Popen logic to a single method This removes 3 lines in total LOC and makes the upcoming changes easier. Differential Revision: https://phab.mercurial-scm.org/D948
