HTML report fails with 'int' object is unsubscriptable

[nedbat]

Hi all,

Running coverage html, I'm running into this exception:

#!python

Traceback (most recent call last):
 File "/srv/bb-master/.local/bin/coverage", line 8, in <module>
   load_entry_point('coverage==3.3.1', 'console_scripts', 'coverage')()

TypeError: Couldn't evaluate {{ totals.pc_covered|format_pct }}: 'int' object is unsubscriptable

Anyone know what's wrong?

Attached is a .coverage file with which I can reproduce this issue. It was generated on an Ubuntu Hardy machine by generating coverage for Twisted. In a Twisted trunk@28817 checkout, this command was run:

coverage run ./bin/trial --reporter=bwverbose twisted

Coverage 3.3.1 was used (installed from source, as that version is not packaged for Hardy AFAICT), along with Python 2.5.2 (Hardy packaged version). The resulting file was then transferred to another Ubuntu Hardy machine and an html report generated using this command:

coverage html -d twisted-coverage --omit /usr,/srv/bb-slave/.local,/srv/bb-slave/Projects,/srv/bb-slave/Run/slave/twisted-coverage.py/Twisted/_trial_temp -i

As you might guess from the omit arguments, the Twisted checkout was in /srv/bb-slave/Run/slave/twisted-coverage.py/Twisted.

The second machine also had Coverage 3.3.1 installed, as well as Python 2.5.2 (Hardy packaged version).

This is because for whatever reason, your HTML report has no files in it. You must be over-constraining the report, or not measuring any data at all somehow.

In <<changeset 99a25749a8d2 (bb)>>, I fixed coverage.py to return a nice exception ("No data to report") rather than trip over itself with subscripted ints.
