This commit updates the test coverage report in include the latest
tests for the recent cgo handling updates for char, unsigned char,
and uint8_t arrays.
This commit adds a script which can be used to generate the test coverage
report. It detects whether or not gcc is installed and adds the necessary
build tag to enable the new cgo tests when gcc is available.
This commit adds tests for the recent cgo handling of char, unsigned char,
and uint8_t arrays.
In addition, it adds an architecture for the cgo specific testing based on
build constraints. This was done because spew itself does not require
cgo, but in order to test its handling of the cgo types it needs to be fed
cgo data. Rather than force all users to have a system which supports cgo
and an external compiler just to run the tests, the cgo test support must
explicitly be turned on via a build tag.
This commit adds support for dumping a few cgo types like hexdump -C as
requested in issue #11. In particular, it now handles char [#], unsigned
char [#], and uint8_t [#].
This commit modifies the code to detect nil slices and display them as
<nil> (as opposed to simply empty slices). For most instances a nil slice
can be treated the same as an empty slice, but there is a difference and
things like reflect.DeepEqual notice. This change makes it clear whether
the type in question is a nil slice or an empty slice.
This commit adds a function named Sdump which works exactly like Dump and
Fdump except it returns the formatted output as a string. This serves the
same purpose as the the Sprint* family of functions.
The name indent better describes the function. This also will help
differentiate the function from planned functions that are intended to
perform padding for the purposes of aligning fields, types, and values.
In order to help future proof itself, spew handles unrecognized reflect
values by passing them on to the standard fmt library. Since spew handles
all current reflect values in the language, this condition has to be
manually tested with a bit of hackery by using unsafe to change the kind
to a nonexistent value.
As of this commit, there is now 100% test coverage.
It was previously possible for an invalid reflect value to lead to a panic
in certain obscure cases. Rather than adding multiple checks for the
invalid reflect value, handle invalid reflect values immediately.
This commit adds tests for a struct which has an embedded struct pointer
and a field that is a pointer to the same object. This ensures the cycle
detection is properly reset between fields.
This commit adds tests for the DisableMethods and DisablePointerMethods
options. All combinations of method options and Stringer interface
invocation for both pointer receivers and non-pointer receivers are
tested.
If a type implements a Stringer or error interface with a pointer receiver
and the value being formatted is addressable, the interface should be
invoked even when the DisablePointerMethods option is set.
DisablePointerMethods is only intended to prevent the potentially unsafe
action of stepping around type-safety restriction to invoke a Stringer or
error interface with a pointer to an unaddressable value.
