I am getting the error in the title when trying to run Apache Bench to test a HTTP endpoint I wrote, but only when specifying a POST file with contents. If I specify an empty file to -p.
I have been trying various solutions found online regarding the encoding and format of the contents, but it seems like just about any content will get this error.
The problem was that when installing Apache Bench from source, I had copied over the ab executable file from httpd/support/bin/.lib/ab to ~/.local/bin. When I did that, it used the system-wide libapr instead of the one I had downloaded to httpd/srclib/apr. This caused some sort of version mismatch, I assume.
The solution was to remove my copy of ab from ~/.local/bin and instead create a script ~/.local/bin/ab with contents
#!/bin/sh
$SRC/httpd/support/ab "$#"
and make this executable with chmod a+x ~/.local/bin/ab.

I'm using WSL with docker (with a complex pandoc configuration with latex, python and pandoc-filters) and trying a long command with --filter=filters/the_filter.sh that results in an error:
Error running filter filters/the_filter.sh: ./filters/the_filter.sh: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)
My filter is a .sh wrapper, mostly to make sure I'm using Python3 (which may not be needed, but I got the hint from here):
#!/bin/sh
python3 filters/the_filter.py $#
Googling the error shows lots of GitHub issues, but no definitive explanation on Stack overflow.
It turns out that my .sh file had Windows line endings: \r\n.
I assume that the system was trying to find /bin/sh\r but the error message is not explaining it.
Correcting the line-endings using dos2unix filters/the_filter.sh, I was able to get rid of the error.
Here are more details of a related problem.
I'm trying to move my few microservices to a docker containers using docker-compose project type from Visual Studio.
I also have Service Fabric project so I have to install Service Fabric SDK into my docker containers.
That's what I do to achieve this (my dockerfile(s)):
FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-nanoserver-1809 AS base
WORKDIR /app
EXPOSE 80
...
WORKDIR /temp
ADD https://aka.ms/vs/15/release/vs_buildtools.exe /temp #C:\TEMP\vs_buildtools.exe
...
The rest code doesn't matter since it crashes on line with ADD command.
The error from Output after I run this via Ctrl+F5:
3>Step 4/11 : ADD https://aka.ms/vs/15/release/vs_buildtools.exe /temp
3>Service 'bmt.microservices.snowforecastcenter' failed to build: ADD failed: CreateFile \\?\C:\ProgramData\Docker\tmp\docker-builder567273413\temp: The system cannot find the file specified.
I don't understand what I'm doing wrong and what does it mean 'system cannot find the file' since I simply load the file from the internet and place it into my newly created \temp folder (the link is valid, I checked).
Does anybody know what this might be related to?
Ok, I've accidentally fixed the problem by moving comment to next line.
From this:
ADD https://aka.ms/vs/15/release/vs_buildtools.exe /temp #C:\TEMP\vs_buildtools.exe
To this:
ADD https://aka.ms/vs/15/release/vs_buildtools.exe /temp
#C:\TEMP\vs_buildtools.exe
Then I red on official site (https://docs.docker.com/engine/reference/builder/#/from) that you cannot have inline comments since they are treated as arguments:
Docker treats lines that begin with # as a comment, unless the line is a valid parser directive. A # marker anywhere else in a line is treated as an argument.
I hope this will help other people who are new in Docker.
I'm following this tutorial and when I get to the part where I call:
cp /tf_files/stripped_retrained_graph.pb bazel-bin/tensorflow/examples/android/assets/stripped_output_graph.pb
and
cp /tf_files/retrained_labels.txt bin/tensorflow/examples/android/assets/imagenet_comp_graph_label_strings.txt
They both say "No such file or directory".
As you can see in this image I can cd to the tf_files folder and see that the files are there.
I can also cd to /tensorflow/tensorflow/examples/android/assets and call ls which shows there's just a BUILD file there.
In the cp command is there supposed to already be a stripped_output_graph.pb file in the destination which gets replaced? Or is it meant to just be creating a new file there?
Is there some way of doing cp [source] [current directory] rather than specifying the destination as a path?
I've tried removing the file path part in hope that it just uses the source filename but that doesn't work.
Calling
cp /tf_files/stripped_retrained_graph.pb /tensorflow/tensorflow/examples/android/assets/stripped_output_graph.pb
and
cp /tf_files/retrained_labels.txt /tensorflow/tensorflow/examples/android/assets/imagenet_comp_graph_label_strings.txt
finally worked, wasn’t at all obvious that I’d have to change the destination path or what it should be though.
Also I accidentally saved a file as .p rather than .pb but managed to remove it using $ docker exec <container> rm -rf /tensorflow/tensorflow/examples/android/asset
s/stripped_output_graph.p
Now I managed to copy the files in correctly, but then when I installed the app it was still just running the regular demo app.
Not sure why it didn’t work, so frustrating.
When I rebuilt it after copying the files in I got these conflict messages
Are these normal to have?
It looks like maybe a different labels file is taking priority over mine, how can I reach the external/inception5h/imagenet_comp_graph_label_strings.txt file to delete it so my file is used instead?
Does the “external” part mean that I can’t actually access it?
I'm using [or, trying to use] the docker cayley from here: https://github.com/saidimu/cayley-docker
I created a data dir at /var/lib/apps/cayley/data and dropped the .cfg file in there that I was instructed to make:
{
"database": "myapp",
"db_path": "/var/lib/apps/cayley/data",
"listen_host": "0.0.0.0"
}
I ran docker cayley with:
docker run -d -p 64210:64210 -v /var/lib/apps/cayley/data/:/data saidimu/cayley:v0.4.0
and it runs fine, I'm looking at it's UI in the browser:
And I add a triple or two, and I get success messages.
Then I go to the query interface and try to list any vertices:
> g.V
and there is nothing to be found (I think):
{
"result": null
}
and there is nothing written in the data directory I created.
Any ideas why data isn't being written?
Edit: just to be sure there wasn't something wrong with my data directory, I ran the local volume mounted docker for neo4j on the same directory and it saved data correctly. So, that eliminates some possibilities.
I can not comment yet but I think to obtain results from your query you need to use the All keyword
g.V().All() // Print All the vertices
OR
g.V().Limit(20) // Limits the results to 20
If that was not your problem I can edit and share my dockerfile which is derived from the same docker-file that you are using.

Trying to get a rails server running nicely.
downloaded ruby 1.8.7 using link from rails page.
did ./configure/make/install, installed it fine.
tried ruby -v , got nothing.
tried ./ruby -v from the folder and it worked.
I feel like i've gone from understanding something about unix, to completely lost. Clearly ruby is working as a 'daemon', but not running as it should. Any help would be MUCH appreciated. Losing too much hair through this process :(
J.
can you see where make install put the ruby executeable?
if you do, check if this dir is in your $PATH by
echo $PATH
In general, unix needs to know where to find the executable file to be able to run it. It uses $PATH to find this executable file.
So if you type "ruby" it will go look at you $PATH and then look in each of those directories for a file named "ruby". If it can't find it in any of those directories it should then also look in the current directory.
So, this whole process will fail if:
a) the directory that contains the executable ruby file is not in any of the directories in $PATH AND
b) the executable is not in the current directory
... one more alternative is that is is available in one of these directories... but is not actually marked as being executable by you. You can check this by making sure you're int e directory with the ruby file and typing "ls -l ./ruby"
That will list the ruby file along with all its permissions and who owns it.
It should be something like:
lrwxrwxrwx 1 root root 7 2010-02-14 10:45 ./ruby
Notice the rwx. If your ruby doesn't have x then you'll need to add executable permission using chmod eg: "chmod 755 ./ruby"
Also note the "root root" - that means it's owned by root - in general, this means that only root can run it. In this particular example it has eXecute permission for everyone so everybody can run it, but if you do not have execute permission set like this, then it means that if you are trying to run it as yourself, you won't have permission, and you should either add full permissions or try running it using: "sudo ruby"
However - by the sounds of it - the most likely problem is that you just don't have the ruby executable's directory in your $PATH. You will need to fix this even if you get it running right now - because, in future, you will need to run ruby from directories other than the current one.
You will need to google for instructions on adding things to your $PATH - because it differs depending on your version of linux and your current shell, but it's not very difficult.
Which shell are you running? If tcsh, you may need a "rehash". Otherwise, as leifg says, add the directory containing the ruby executable to your path.
