Our assembly cache contains assemblies that are explicitly loaded by powershell egine, such as via module loading or the assembly entries from InitialSessionState. We should search it before searching all loaded assemblies to give preference to resolve a type against the assemblies contained in the cache, so that in case there is a conflict, we might have a preferred assembly to use for a type resolution.
Changes:
- Search from context.AssemblyCache.Values before search from all loaded assemblies.
- Skip assemblies that we already searched and found no matching type.
- Skip checking PS types kept in the scope and type accelerators when it's not necessary.
* Fix GetType() bad pattern and related issues in tests
$var.GetType() can raise an exception in tests so we should check $var
before make the call. A large part of the tests does not make this
check.
I start with searching ".GetType()" but discovered many related issues
in tests (reduntant and unneeded tests, "throw" bad pattens, bugs,
formattings (sorry!) and so on) - I had to fix them too.
* Fix after code review
* Second wave of migration GetType() -> BeOfType
Removed 'GetType().Name' patterns.
Interactive hosts expect an `IncompleteParseException` to signal that more input is expected.
When detecting errors, the parser can report 2 positions:
* where the error should be reported
* where the error was detected
Typically these are the same, so most error reporting methods have a single parameter.
For missing braces, the pattern is supposed to be to report the error after the opening brace, but the error is typically detected at the end of the file.
There were a few places where we were not consistent in reporting such errors, this PR corrects those places.
Native argument completers were not invoked when the argument was a single dash.
The fix is to treat unbound command parameters as command arguments for the purposes of parameter/argument completion.
* Make small optimization in parser tests
* Add Clear() for common command
Remove commands from AfterEach
* Refactoring test 'functions are resolved before cmdlets'
The tokenizer did multiple scans the script line to get tokens. Before
the fix the tokenizer on the first pass examined that string as
double-quoted (Expandable) string not as here string, figured the
average double quotation mark as a closing and then starting with the
single quotation mark continued processing the line as single-quoted
string which had no closing single quotation mark.
The fix is to stop the first scan pass after getting '=' (assume
assignment-expression '$a=' for next pass).
People use Out-Null despite much faster alternatives:
$null = Do-Stuff
[void] = Do-Stuff
Do-Stuff > $null
This change makes Out-Null work in roughly the same say as the above.
The optimization is to detect that we're calling the built-in Out-Null
cmdlet when invoking a pipeline from script (the change won't have any
effect in the PowerShell api). If we detect Out-Null, we rewrite the
pipe to look similar to `Do-Stuff > $null`.
1. Added parameterbinding test
2. Added ShouldBeErrorID function in helper file
3. Removed ShouldBeErrorID function from other test modules
4. Update New-TestHost to be able to run on full CLR
5. updated file map.json
