From: Richard Si <63936253+ichard26@users.noreply.github.com> Date: Sat, 30 Jul 2022 03:28:43 +0000 (-0400) Subject: Remove blib2to3 grammar cache logging (#3193) X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/d85cf00ee80f00b25a819afef7f466dc871fa68d?ds=inline Remove blib2to3 grammar cache logging (#3193) As error logs are emitted often (they happen when Black's cache directory is created after blib2to3 tries to write its cache) and cause issues to be filed by users who think Black isn't working correctly. These errors are expected for now and aren't a cause for concern so let's remove them to stop worrying users (and new issues from being opened). We can improve the blib2to3 caching mechanism to write its cache at the end of a successful command line invocation later. --- diff --git a/CHANGES.md b/CHANGES.md index e027b2c..a30ac7f 100644 --- a/CHANGES.md +++ b/CHANGES.md @@ -54,6 +54,8 @@ - Change from deprecated `asyncio.get_event_loop()` to create our event loop which removes DeprecationWarning (#3164) +- Remove logging from internal `blib2to3` library since it regularily emits error logs + about failed caching that can and should be ignored (#3193) ### Packaging diff --git a/src/blib2to3/pgen2/driver.py b/src/blib2to3/pgen2/driver.py index 8fe8206..daf271d 100644 --- a/src/blib2to3/pgen2/driver.py +++ b/src/blib2to3/pgen2/driver.py @@ -263,14 +263,13 @@ def load_grammar( logger = logging.getLogger(__name__) gp = _generate_pickle_name(gt) if gp is None else gp if force or not _newer(gp, gt): - logger.info("Generating grammar tables from %s", gt) g: grammar.Grammar = pgen.generate_grammar(gt) if save: - logger.info("Writing grammar tables to %s", gp) try: g.dump(gp) - except OSError as e: - logger.info("Writing failed: %s", e) + except OSError: + # Ignore error, caching is not vital. + pass else: g = grammar.Grammar() g.load(gp)
