I use #babel/preset-env + babel-polyfill + corejs3 with "useBuiltIns": "usage" in .babelrc config.
I use browserlist to target the following browsers:
ie >= 9
edge >= 12
firefox >= 36
chrome >= 49
safari >= 10
I found that some ES3 features are polyfilled even they are considered available to all target browsers (according to CanIUse):
[/app/src/myscript.js] Added following core-js polyfills:
es.array.concat { "chrome":"49", "edge":"12", "firefox":"36", "ie":"9" }
es.array.slice { "chrome":"49", "edge":"12", "firefox":"36", "ie":"9" }
My goal is to minimize the file size and remove unnecessary polyfills.
My questions is: Why babel-polyfill decided to add those polyfills for es3 features ?

I managed to fix it on High Sierra(10.13.1) XCode 9.1 and with iOS 11.0.3 by defining OS_ACTIVITY_MODE as disable by going in XCode via
Product > Scheme > Edit Scheme > Arguments > Environment Variables
add OS_ACTIVITY_MODE disable

I have set the GST_PLUGIN_PATH_1_0 environment variable to "/usr/local/lib:/usr/local/lib/gstreamer-1.0:/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu/gstreamer-1.0"
I compiled and installed gstreamer1.0-1.2.4, together with the base, good, bad and ugly packages for that version. GES is installed with version 1.2.1 as this was the nearest to the gstreamer version I found. I also installed the libav-1.2.4.
The decodebin2 should be in base according to the make install log for plugin-base and is linked into libgstplayback, which is part of my GST_PLUGIN_PATH_1_0:
/usr/local/lib/gstreamer-1.0 libgstplayback_la-gstdecodebin2.lo
I do have gstreamer0.10 and the decodebin2 is there as a blacklisted version when I do 'gst-inspect-1.0 -b' as it sits in the gstreamer0.10 library path rather than on that for 1.0.
I tried clearing the ~/.cache/gstreamer files and running gst-inspect-1.0 again to regenerate the plugin registry but I still keep getting the error in the Python code. This sample code might be wrong as it is my first stab at writing a timeline using Gstreamer editing services. I am on Ubuntu Trusty or 14.04.
The file is an mp4 file which is why I installed gst-libav for the required libraries.

There is no "decodebin2" in GStreamer 1.x, which you're using here. It's just called "decodebin" now and is equivalent to "decodebin2" in 0.10.
Your problem here however is not that decodebin is not found. Your problem is that you're missing a plugin to play this specific media file. What kind of media file is it?
I have a testcase in which the behavior seems wrong. I see that in all generations the num_of_red_shoes is high, while I would expect a more even distribution. What is the cause of this behavior and how can it be fixed?

keep soft num_of_black_shoes < 10;
keep soft num_of_yellow_shoes < 10;
keep num_of_yellow_shoes + num_of_black_shoes + num_of_red_shoes == num_of_shoes;

When there are contradicting soft constraints, Specman does not randomize the softs which are enforced, but rather gives priority to the constraints which were written last. Since the soft on red shoes was first in the test, it is the one which is always overridden.
If the softs are known to be mutually exclusive (which is not the case here) you could use a simple flag to randomly choose which soft should hold. e.g. the code would look like this:
flag:uint[0..2];
keep soft read_only(flag==0) => num_of_red_shoes < 10;
keep soft read_only(flag==1) => num_of_black_shoes < 10;
keep soft read_only(flag==2) => num_of_yellow_shoes < 10;
However, since here there is no knowledge in advance how many softs are expected to hold (and it's possible and two or all three will be satisfied) a more complex solution should be made. Here is a code which does this randomization:
struct closet {
kind:[SMALL,BIG];
num_of_shoes:uint;
num_of_red_shoes:uint;
num_of_black_shoes:uint;
num_of_yellow_shoes:uint;
//replaces the original soft constraints (if a flag is true the correlating
//right-side implication will be enforced
soft_flags[3]:list of bool;
keep for each in soft_flags {
soft it == TRUE;
};
//this list is used to shuffle the flags so their enforcement will be done
//with even distribution
soft_indices:list of uint;
keep soft_indices.is_a_permutation({0;1;2});
keep soft_flags[soft_indices[0]] => num_of_red_shoes < 10;
keep soft_flags[soft_indices[1]] => num_of_black_shoes < 10;
keep soft_flags[soft_indices[2]] => num_of_yellow_shoes < 10;
keep num_of_yellow_shoes + num_of_black_shoes + num_of_red_shoes == num_of_shoes;
};
I'm not with Cadence, so I can't give you a definite answer. I think the solver will try to break as few constraints as possible and it just chooses the first one if finds (in your case the one for red shoes). Try changing the order and see if this changes (if the black constraint is first, I'd think you'll always get more black shoes).
As a solution, you could just remove the soft constraints when you have a big closet:
when BIG closet {
keep num_of_red_shoes.reset_soft();
keep num_of_black_shoes.reset_soft();
keep num_of_yellow_shoes.reset_soft();
keep num_of_shoes in [50..100];
};
If you want to randomly choose which one of them to disable (sometimes more than 10 red shoes, sometimes more than 10 black shoes, etc.), then you'll need a helper field:
when BIG closet {
more_shoes : [ RED, BLACK, YELLOW ];
keep more_shoes == RED => num_of_red_shoes.reset_soft();
keep more_shoes == BLACK => num_of_black_shoes.reset_soft();
keep more_shoes == YELLOW => num_of_yellow_shoes.reset_soft();
keep num_of_shoes in [50..100];
};
It depends on what you mean by "a more even distribution".
There is no way to satisfy all of your hard and soft constraints for a BIG closet. Therefore Specman attempts to find a solution by ignoring some of your soft constraints. The IntelliGen constraint solver doesn't ignore all of the soft constraints, but attempts to find a solution while still using a subset. This is explained in the "Specman Generation User Guide" (sn_igenuser.pdf):
[S]oft constraints that are loaded later are considered to have a higher priority than soft constraints loaded previously."
In this case that means that Specman discards the soft constraint on red shoes and since it can find a solution still obeying the other soft constraints it does not discard them.
If you combine all of your soft constraints into one, then you will probably get the result you were hoping for:
keep soft ((num_of_red_shoes < 10) and (num_of_black_shoes < 10) and
(num_of_yellow_shoes < 10));
There are advantages to giving later constraints priority: This means that using AOP you can add new soft constraints and they will get the highest priority.
For more distributed values, I would suggest the following.
I'm sure you can follow the intended logic too.
var1, var2 : uint;
keep var1 in [0..30];
keep var2 in [0..30];
when BIG closet {
keep num_of_shoes in [50..100];
keep num_of_yellow_shoes == (num_of_shoes/3) - 15 + var1;
keep num_of_black_shoes == (num_of_shoes - num_of_yellow_shoes)/2 - 15 + var2;
keep num_of_red_shoes == num_of_shoes - (num_of_yellow_shoes - num_of_black_shoes);
keep gen (var1, var2) before (num_of_shoes);
keep gen (num_of_shoes) before (num_of_yellow_shoes, num_of_black_shoes, num_of_red_shoes);
keep gen (num_of_yellow_shoes) before (num_of_black_shoes, num_of_red_shoes);
keep gen (num_of_black_shoes) before (num_of_red_shoes);
};
The challenge is that I'm checking my FoxPro code into source control (using Mercurial, but that's not the focus of this question) and would like a quick way to get the FoxPro SCCTEXT output alongside the binary output without using the Tools > Options > Projects > Active source control provider functionality.
For an example of the kind of output I'm looking to generate, the VFPX source contains many of these text .sca, .vca, etc. files. Is there any way to generate these files on demand?
Rather than setting a source control provider, you can hack scctext.prg (which ships with VFP) and use a project hook to generate the files - see http://paulmcnett.com/scX.php for an example implementation using Subversion.
Edit: Have you looked at the Alternate SCCText on Codeplex
Also see http://www.foxpert.com/docs/cvs.en.htm for another perspective.
Here is the code I use to genereate SCCText files for every file in my Project file. Just open your Project (to make sure it is the Active Project, then run this prg file).
(Updated 2011-06-10: Added a new feature that will only build new SCC text files if the DateTime of the original source file is newer than the existing SCC file. Essentially, this new version only generates a new SCC file if the VFP source file has been changed since the last time this was run.)
