How to get path excludes working in Madge? - madge

I'm trying to run madge on a fairly big typescript project. Its compiled output goes to dist/*, and its React frontend are in public/*. Madge's documentation is pretty clear about how to exclude directories, but no matter what I try, it appears to still be checking these directories.
First attempt:
madge --circular --extensions ts,js --exclude '^(dist|public)' --ts-config ./tsconfig.json --warning .
The reason I think it's still checking there is because, first, I still see it scanning those directories as it runs:
And also, its warnings show imports that only occur in public/:
(the '#'-style import is from module-alias)
What I've tried:
Using a regex like ^.*public.*$
Specifying the excludes in .madgerc rather than on cli:
{
"fileExtensions": ["js","ts"],
"tsConfig": "tsconfig.json",
"excludeRegExp": ["^.*dist.*$", "^.*public.*$"]
}
Running with --debug (the output is so massive I can't really make much of it - if I run it to console it crashes with out-of-memory, and if I pipe to a file, it gets so big that it literally fills up my SSD - I had to cancel when the log file surpassed 25 gigs).
Interestingly, it doesn't seem to be reporting any cycles in public/ or dist/, so I think it might be "partially" working. However, it does still seem to be scanning & processing those excluded paths, so I can't get rid of all the warnings that shouldn't be relevant to this run.

parcel watch only detects first file change

I have the following in ./js/parcel/build-js.js (it is more or less a simplification of exactly what the API docs example does, except that it takes an optional --watch argument):
#!/usr/bin/env node
const Bundler = require('parcel-bundler');
const path = require('path');
const watch = process.argv.indexOf('--watch') > 0;
if (watch) console.log('Watching files...');
(async function bundleJs() {
const jsBundler = new Bundler(path.join(__dirname, '../src/common.js'), {
watch,
hmr: false,
});
jsBundler.on('bundled', () => {
console.log('bundled!');
});
const bundle = await jsBundler.bundle();
console.log('done');
})();
When I run node js/parcel/build-js.js --watch, it detects the first change to src/common.js and prints:
Watching files...
✨ Built in 585ms.
bundled!
done
This is as I'd expect. When I edit and save src/common.js, it sees that and then the total output becomes (done gets deleted):
Watching files...
✨ Built in 585ms.
bundled!
✨ Built in 86ms.
bundled!
But after that, no file changes are detected. I make changes and save but it just sits there, producing no more output or updating the build. Why only once?
Note: If I do strace node js/parcel/build-js.js --watch, it seems to just sit on an unfinished epoll_wait(3,, which I guess means it's waiting for something, but maybe watching the wrong file...
Edit: Versions!
parcel-bundler: 1.12.3
node: 10.15.1
Ubuntu 18.04
Edit: using parcel watch
This appears to be a system-wide thing for me. I did yarn globals add parcel (which also installed 1.12.3), and now watching any JS file with parcel watch path/to/file.js does the same thing.
It turned out to be a conflict between Parcel's change detection and the default Vim setup. From the Hot Module Replacement docs:
Some text editors and IDE's have a feature called safe write that basically prevents data loss, by taking a copy of the file and renaming it when saved.
When using Hot Module Reload (HMR) this feature blocks the automatic detection of file updates, to disable safe write use the options provided below:
I added set backupcopy=yes to my .vimrc and it started working.
The solution for other editors is documented there as well.
It is a Parcel issue! I dropped it (until they fix it)
IMHO: I do not have to change my editor's behavior just to make bundler work correctly. (webpack works fine in the situation)

How can I get "HelloWorld - BitBake Style" working on a newer version of Yocto?

In the book "Embedded Linux Systems with the Yocto Project", Chapter 4 contains a sample called "HelloWorld - BitBake style". I encountered a bunch of problems trying to get the old example working against the "Sumo" release 2.5.
If you're like me, the first error you encountered following the book's instructions was that you copied across bitbake.conf and got:
ERROR: ParseError at /tmp/bbhello/conf/bitbake.conf:749: Could not include required file conf/abi_version.conf
And after copying over abi_version.conf as well, you kept finding more and more cross-connected files that needed to be moved, and then some relative-path errors after that... Is there a better way?
Here's a series of steps which can allow you to bitbake nano based on the book's instructions.
Unless otherwise specified, these samples and instructions are all based on the online copy of the book's code-samples. While convenient for copy-pasting, the online resource is not totally consistent with the printed copy, and contains at least one extra bug.
Initial workspace setup
This guide assumes that you're working with Yocto release 2.5 ("sumo"), installed into /tmp/poky, and that the build environment will go into /tmp/bbhello. If you don't the Poky tools+libraries already, the easiest way is to clone it with:
$ git clone -b sumo git://git.yoctoproject.org/poky.git /tmp/poky
Then you can initialize the workspace with:
$ source /tmp/poky/oe-init-build-env /tmp/bbhello/
If you start a new terminal window, you'll need to repeat the previous command which will get get your shell environment set up again, but it should not replace any of the files created inside the workspace from the first time.
Wiring up the defaults
The oe-init-build-env script should have just created these files for you:
bbhello/conf/local.conf
bbhello/conf/templateconf.cfg
bbhello/conf/bblayers.conf
Keep these, they supersede some of the book-instructions, meaning that you should not create or have the files:
bbhello/classes/base.bbclass
bbhello/conf/bitbake.conf
Similarly, do not overwrite bbhello/conf/bblayers.conf with the book's sample. Instead, edit it to add a single line pointing to your own meta-hello folder, ex:
BBLAYERS ?= " \
${TOPDIR}/meta-hello \
/tmp/poky/meta \
/tmp/poky/meta-poky \
/tmp/poky/meta-yocto-bsp \
"
Creating the layer and recipe
Go ahead and create the following files from the book-samples:
meta-hello/conf/layer.conf
meta-hello/recipes-editor/nano/nano.bb
We'll edit these files gradually as we hit errors.
Can't find recipe error
The error:
ERROR: BBFILE_PATTERN_hello not defined
It is caused by the book-website's bbhello/meta-hello/conf/layer.conf being internally inconsistent. It uses the collection-name "hello" but on the next two lines uses _test suffixes. Just change them to _hello to match:
# Set layer search pattern and priority
BBFILE_COLLECTIONS += "hello"
BBFILE_PATTERN_hello := "^${LAYERDIR}/"
BBFILE_PRIORITY_hello = "5"
Interestingly, this error is not present in the printed copy of the book.
No license error
The error:
ERROR: /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb: This recipe does not have the LICENSE field set (nano)
ERROR: Failed to parse recipe: /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb
Can be fixed by adding a license setting with one of the values that bitbake recognizes. In this case, add a line onto nano.bb of:
LICENSE="GPLv3"
Recipe parse error
ERROR: ExpansionError during parsing /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb
[...]
bb.data_smart.ExpansionError: Failure expanding variable PV_MAJOR, expression was ${#bb.data.getVar('PV',d,1).split('.')[0]} which triggered exception AttributeError: module 'bb.data' has no attribute 'getVar'
This is fixed by updating the special python commands being used in the recipe, because #bb.data was deprecated and is now removed. Instead, replace it with #d, ex:
PV_MAJOR = "${#d.getVar('PV',d,1).split('.')[0]}"
PV_MINOR = "${#d.getVar('PV',d,1).split('.')[1]}"
License checksum failure
ERROR: nano-2.2.6-r0 do_populate_lic: QA Issue: nano: Recipe file fetches files and does not have license file information (LIC_FILES_CHKSUM) [license-checksum]
This can be fixed by adding a directive to the recipe telling it what license-info-containing file to grab, and what checksum we expect it to have.
We can follow the way the recipe generates the SRC_URI, and modify it slightly to point at the COPYING file in the same web-directory. Add this line to nano.bb:
LIC_FILES_CHKSUM = "${SITE}/v${PV_MAJOR}.${PV_MINOR}/COPYING;md5=f27defe1e96c2e1ecd4e0c9be8967949"
The MD5 checksum in this case came from manually downloading and inspecting the matching file.
Done!
Now bitbake nano ought to work, and when it is complete you should see it built nano:
/tmp/bbhello $ find ./tmp/deploy/ -name "*nano*.rpm*"
./tmp/deploy/rpm/i586/nano-dbg-2.2.6-r0.i586.rpm
./tmp/deploy/rpm/i586/nano-dev-2.2.6-r0.i586.rpm
I have recently worked on that hands-on hello world project. As far as I am concerned, I think that the source code in the book contains some bugs. Below there is a list of suggested fixes:
Inheriting native class
In fact, when you build with bitbake that you got from poky, it builds only for the target, unless you mention in your recipe that you are building for the host machine (native). You can do the latter by adding this line at the end of your recipe:
inherit native
Adding license information
It is worth mentioning that the variable LICENSE is important to be set in any recipe, otherwise bitbake rises an error. In our case, we try to build the version 2.2.6 of the nano editor, its current license is GPLv3, hence it should be mentioned as follow:
LICENSE = "GPLv3"
Using os.system calls
As the book states, you cannot dereference metadata directly from a python function. Which means it is mandatory to access metadata through the d dictionary. Bellow, there is a suggestion for the do_unpack python function, you can use its concept to code the next tasks (do_configure, do_compile):
python do_unpack() {
workdir = d.getVar("WORKDIR", True)
dl_dir = d.getVar("DL_DIR", True)
p = d.getVar("P", True)
tarball_name = os.path.join(dl_dir, p+".tar.gz")
bb.plain("Unpacking tarball")
os.system("tar -x -C " + workdir + " -f " + tarball_name)
bb.plain("tarball unpacked successfully")
}
Launching the nano editor
After successfully building your nano editor package, you can find your nano executable in the following directory in case you are using Ubuntu (arch x86_64):
./tmp/work/x86_64-linux/nano/2.2.6-r0/src/nano
Should you have any comments or questions, Don't hesitate !

Testing for LibreSSL in a Perl build script

I released Net::NSCAng::Client a while ago and am getting a lot of test failures on OpenBSD. The reason for that is that the NSCAng protocol uses OpenSSL in preshared-key mode (RFC4279), something the folks at LibreSSL (default on OpenBSD now) have ripped out. However, they seem to have been hell-bent on doing this the most intransparent way: the include files have all the functions defined, just the shared library is missing the corresponding symbols, so compilation works fine but the tests fail.
There is a compatibility package on OpenBSD called eopenssl, and by testing for this first in Makefile.PL (using ExtUtils::PkgConfig) I can make it work if the compatibility library is installed. If it isn't, things still fail.
I could check for the CPP symbol OPENSSL_NO_PSK, but as the includes always come from LibreSSL, this fails even if linking with eopenssl would work fine. The only idea I have left is to try and have a test program run as part of the compilation phase as autoconf does it. Is that even possible with ExtUtils::MakeMaker (or something else -- I wouldn't mind switching the build system if necessary)?
It's easy to write feature tests with Devel::CheckLib. Something like the following can be used to check for the presence of function your_func (in Makefile.PL):
my $your_func_exists = check_lib(
header => 'your_header.h',
function => 'return your_func ? 1 : 0;',
);
If you simply want to abort compilation if the function is missing:
check_lib(
...
) or warn('your_func is missing'), exit;
Exiting with 0 should avoid a CPAN Tester's 'FAIL' report.

How to get Resharpers InspectCode to recognize Plugins?

I am trying to run ReSharpers command line tool InspectCode.exe. It's running fine doing it's job with the expected output.
However after my earlier attempt to get plugins to work, this time with the new version it is supposed to be supported. There is a switch in the command line interface that allows to specify the extension you want to use.
/extensions (/x) – allows using ReSharper extensions that affect code analysis. To use an extension, specify its ID, which you can find by opening the extension package page in the ReSharper Gallery, and then the Package Statistics page. Multiple values are separated with the semicolon.
But I cannot get it to work properly. I cannot even provoke any reaction to the /x switch at all. No matter how or what I pass, I get no feedback from the executable and the output is identical. I don't even get an error message when passing obvious garbage.
I tried the following commandlines for the exact same result:
inspectcode.exe /o="rcli.xml" /swea /x="ReSharper.StyleCop" "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ReSharper.StyleCop "my.sln"
inspectcode.exe /o="rcli.xml" /swea "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ABCDEFG "my.sln"

What am I doing wrong? How to get extensions to work?
I already tried the R# forums, but it took them more then 24h to approve my post and so far I'm not sure someone else even read it.
Unfortunately, the support for extensions was dropped in 9.0 due to the refactorings in the "ReSharper platform". I hope that JetBrains will bring it back soon.
See RSRP-436208.
This is a late answer that might help future readers (like myself). Currently inspectcode.exe will automatically look for and use any NuGet packages that are in the same folder as the executable (source).
Example for CleanCode extension:
if you have a R# instance on some machine and install the extension, it will be placed in C:\Users\{user}\AppData\Local\JetBrains\plugins\MO.CleanCode.5.6.15
copy MO.CleanCode.5.6.15.nupkg and paste it next to inspectcode.exe
when running inspectcode with verbosity = VERBOSE, the extension should appear in the Zones list:
$cmd = "..\JetBrains.ReSharper.CommandLineTools.2019.3.4\inspectcode.exe"
$outputFile = "..\Output\$($outputName).xml"
& $cmd -o="$outputFile" $sln --verbosity=VERBOSE

Algebra filter error in moodle

I installed moodle 1.9.12 and now I want to use Algebra notation in content. I enable "TeX Notation" and "Algebra Notation" in administrator panel and also install mimetext and dvips and Imagemagic on the server. fortunately Tex Notation works fine but I got the following error for Algebra:
sh: /var/www/html/moodle/filter/tex/mimetex.linux: not found
The shell command
"/var/www/html/moodle/filter/tex/mimetex.linux" -e "/var/www/moodledata/filter/algebra/de06d6c44d98ba4e42dffca988bf530b.gif" -- '\Large \frac{\sin\left(z\right)}{x^{2}+y^{2}}'
returned status = 127
File size of mimetex executable /var/www/html/moodle/filter/tex/mimetex.linux is 830675
The file permissions are: 100775
The md5 checksum of the file is 56bcc40de905ce92ebd7b083c76e019e
Image not found!
Note: /var/www/html/moodle/filter/tex/mimetex.linux exists on the server and is executable!!!
What is the problem?? Any idea?????
From what you have described, calling the general tex filter debug page works and does not show up the same error.
/filter/tex/texdebug.php works, but /filter/algebra/algebradebug.php does not.
If this is the case, perhaps you could check for an open_basedir, or safe_mode_exec_dir being set to include the current working directory, or otherwise restricting the execution of /var/www/html/moodle/filter/tex/mimetex.linux, while the current working directory is /var/www/html/moodle/filter/algebra.
You could look at this by visiting /admin/phpinfo.php at your site, and look carefully at the effective values of open_basedir, safe_mode and safe_mode_exec_dir.
You could also check the apache error log or add the following lines to the top of the algebra debug php file, and you might see some extra error messages:
$CFG->debug = 6143 ;
$CFG->debugdisplay= 1 ;
Hope that helps
