This closes `issue 754`*. The fix was contributed by `Daniel Diniz <pull 1773_>`*. - Fix: very complex source files like `this one <resolvent_lookup_>`\_ could cause a maximum recursion error when creating an HTML report. This is now fixed, closing `issue 1774`\_. - HTML report improvements: - Support files (JavaScript and CSS) referenced by the HTML report now have hashes added to their names to ensure updated files are used instead of stale cached copies. - Missing branch coverage explanations that said "the condition was never false" now read "the condition was always true" because it's easier to understand. - Column sort order is remembered better as you move between the index pages, fixing `issue 1766`*. Thanks, `Daniel Diniz <pull 1768_>`*. .. \_resolvent_lookup: https://github.com/sympy/sympy/blob/130950f3e6b3f97fcc17f4599ac08f70fdd2e9d4/sympy/polys/numberfields/resolvent_lookup.py .. \_issue 754[https://github.com/nedbat/coveragepy/issues/754](https://github.com/nedbat/coveragepy/issues/754)54 .. \_issue 176[https://github.com/nedbat/coveragepy/issues/1766](https://github.com/nedbat/coveragepy/issues/1766)766 .. \_pull 17[https://github.com/nedbat/coveragepy/pull/1768](https://github.com/nedbat/coveragepy/pull/1768)1768 .. \_pull 1[https://github.com/nedbat/coveragepy/pull/1773](https://github.com/nedbat/coveragepy/pull/1773)/1773 .. \_issue [https://github.com/nedbat/coveragepy/issues/1774](https://github.com/nedbat/coveragepy/issues/1774)s/1774 .. \_changes\_7-5-0: </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Enabled. ♻ **Rebasing**: Whenever PR becomes conflicted, or you tick the rebase/retry checkbox. 🔕 **Ignore**: Close this PR and you won't be reminded about this update again. --- - [ ] <!-- rebase-check -->If you want to rebase/retry this PR, check this box --- This PR has been generated by [Mend Renovate](https://www.mend.io/free-developer-tools/renovate/).

PythonParser.lines_matching()records a set of lines matching a given regex. However, it doesn't take multi-line statements into account. That causes statements that should be marked as "# pragma: no branch" to be counted as partial branches. IOW, "a pragma comment on the continuation lines of a multi-line if-statement won't have an effect".This PR fixes that by mapping line numbers through
parser._multiline, so that the number of the first line in a multi-line statement gets recorded instead.Fixes #754.
