[New-bugs-announce] [issue27762] ConfigParser ignores in-line comments for lines with semi-colons

[Joshua Haas]

New submission from Joshua Haas:

According to the 2.7 docs at https://docs.python.org/2/library/configparser.html, you can create in-line comments using ";" if it is preceded by white space.

However, if the value of a config option contains a semi-colon, for example "password=my;pass123", then only the first colon will be checked by the parser.

In the config file:
password=my;pass123 ;expires in 2018

Expected value:
my;pass123

Returned value:
my;pass123 ;expires in 2018

This is easily remedied with a while loop, lines 525-529 in the attached patch. Otherwise the docs should be changed to reflect this behavior, but a patch definitely seems more appropriate to me. Python 3.5 gives the expected value when using inline_comment_prefixes=';'.
