By allowing partial matches of selectors there are chances of collisions
such as those in issue #145, this removes it to expect explicit packages
for each rule.
Closes#145
- Get rid of 'core' and move CLI to cmd/gas directory
- Migrate (most) tests to use Ginkgo and testutils framework
- GAS now expects package to reside in $GOPATH
- GAS now can resolve dependencies for better type checking (if package
on GOPATH)
- Simplified public API
The filelist test was non-deterministic and causing intermittent
failures due to ordering. This change will ensure that the file list
returns an ordered list of files in the String() method now.
Additionally there were a number of test cases that the sample code
was incorrect, or would not compile. These have also been corrected.
This will hopefully reduce the number of false positives when it comes
to hard coded credentials. The zxcvbn library is used to calculate the
entropy of the string. By default the first 16 characters are considered
as doing the entropy check for strings much longer than that introduces
a fairly significant performance hit.
There were several issues with the error test case that have been
addressed in this commit.
- It is possible to specify a whitelist of calls that error handling
should be ignored for.
- Additional support for ast.ExprStmt for cases where the error is
implicitly ignored.
There were several other additions to the helpers and call list in order
to support this type of functionality.
Fixes#54
Update the AddRule interface to allow rules to register interest in
multiple ast.Nodes. Adds more flexibility to how rules can work, and was
needed to fix the hard coded credentials test specifically.
There seems to be an inconsistency in the way that the type.Info.Uses
map is populated by the type checker in Go 1.5 and the latest release.
It is possible to ascertain the package that relates to an object 1.7.x
release but this does not work for earlier Go versions.
To work around this limitation we now track imports, and monitor if they
are aliased or initalization only imports.
This makes the following changes:
- riles are identified by an ID
- include / exclude list now work
- rules are selected based on these lists
- blacklist rules are broken out into methods
- rule constructors now take the config map
- config file can be used to select rules
- CLI options embelish config selection options
This re-works the way that CLI options are passed through to the
analyzer so that they can act as overrides for config options. If
not given on the CLI, options will come from a config file. If no
file is used then a default value is chosen.
Two lists are also populated with tests to include or exclude.
These lists are not used for now but will eventually replace the
way we select test to run in a future patch to follow.
Creating a new generic blacklist rule and removing the older
specific ones. This will need configuration integration when
we have some.
The new test is immune to import aliasing but not shadowing
A CLI option can now be given to tell GAS it should parse data
from a JSON file. Fatal errors are given if the file is not
readable or is not valid JSON.
There are some cases where the '.' character would also match any
character and could lead to incorrect results. For example the
regular expression - `^ioutils.WriteFile$' would match
ioutils.WriteFile, but also ioutils_WriteFile.
Additionally made sure that all regexp were declared using raw
strings to avoid any unnecesary string escaping that potentially
make the regexp difficult to read.
The logic around annotations (nosec) was broken, meaning they were
ignored by default and would not skip sub-blocks. This fixes the
problem and also adds a test to make sure it wont be broken in the
future. Closes#25
Check right-hand side expr for literals when looking for hard-coded
credentials. This is to avoid issuing warnings for cases where a
password, token, etc. is read from a file or a terminal.
This prevents the string concat tests flagging a false positive if
joining two literal strings (eg "SELECT * FROM " + " table" ... )
or with a constant (eg const tab = "name"; "SELECT * from " + tab)
Go code running under CGI is vulnerable to httpoxy attack. See
https://httpoxy.org/ this checks for an import of net/http/cgi
that might indicate code may be run under CGI.
