The pattern test method `test_rule_patterns` tests each rule by
fetching two strings from it: `test_good` and `test_bad`. Each
string is then presented as an input file to `custom_check_file`,
which should return True or False.
All lines in a string need to end with `\n`. Since the linter
expects an additional newline at the end of a file, the test case
adds `\n` to each string on top of that.
Fixes#6320.
This enforces our use of a consistent style in how we access Python
modules; "from os.path import dirname" is a particularly popular
abbreviation inconsistent with our style, and so it deserves a lint
rule.

Fixes#6543.
We want to convert stream names to stream ids as close
to the "edges" of our system as possible, so we let our
caller do the work of finding the stream id for a stream
narrow.
There are four regexes which try to ensure that the i18n strings are
properly captured.
1) The one which disallows multiline strings.
```
i18n\.t\([^)]+[^,\{\)]$
// Disallows:
i18n.t('some '
+ 'text');
```
2) The one which disallows concatenation within argument to i18n.t():
```
i18n\.t\([\'\"].+?[\'\"]\s*\+
// Disallows:
i18n.t("some " + "text");
```
3) There are two which disallow concatenation with i18n.t():
```
i18n\.t\(.+\).*\+
// Disallows:
i18n.t('some text') +
\+.*i18n\.t\(.+\)
// Disallows:
+ i18n.t('some text')
```
The ideal case is that you try to bring the string argument to the
i18n.t() on one line. In case this is not possible, you can do the
following:
```
var1 = i18n.t("Some text to be translated");
var2 = i18n.t("Some more text to be translated");
complete = var1 + var2;
This is needed in order to mock the method when testing
`custom_check.py`. The diff for this commit is a bit broken;
all it really does is moving the method out of `build_custom_checkers`.
We were getting pyflakes lint error output without line numbers like
this:
pyflakes | if user_profile.is_realm_admin and
pyflakes | ^
pyflakes |
Apparently the cause was that stdout and stderr was getting mixed
badly, creating "unused import"s lines that had the first of that
error (containing the line number) just above.
As a result, printing out the lines of output from pyflakes' merged
stdout/stderr feed looked like this:
b"zproject/settings.py:95: 'from .prod_settings import *' used; unable to detect undefined nameszerver/views/users.py:49:39: invalid syntax\n"
Note the lack of newline in between the end of the first error at
"names" and the start of the second at "zerver".
This appears to be a change in Pyflakes behavior when we switched to
Python 3; probably they're missing a flush() somewhere.
We're about to do this (a) in a number of places mentioning
system packages like `python3-dev` to install, and (b) in the
shebangs of every script in the tree.
