            How to install local package with conda
            Asked 2022-Feb-05 at 04:16

            I have a local python project called jive that I would like to use in an another project. My current method of using jive in other projects is to activate the conda env for the project, then move to my jive directory and use python setup.py install. This works fine, and when I use conda list, I see everything installed in the env including jive, with a note that jive was installed using pip.

            But what I really want is to do this with full conda. When I want to use jive in another project, I want to just put jive in that projects environment.yml.

            So I did the following:

            1. write a simple meta.yaml so I could use conda-build to build jive locally
            2. build jive with conda build .
            3. I looked at the tarball that was produced and it does indeed contain the jive source as expected
            4. In my other project, add jive to the dependencies in environment.yml, and add 'local' to the list of channels.
            5. create a conda env using that environment.yml.

            When I activate the environment and use conda list, it lists all the dependencies including jive, as desired. But when I open python interpreter, I cannot import jive, it says there is no such package. (If use python setup.py install, I can import it.) How can I fix the build/install so that this works?

            Here is the meta.yaml, which lives in the jive project top level directory:

            ANSWER

            Answered 2022-Feb-05 at 04:16

            The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment.

            I think the main issue is that python >=3.5 is only a valid constraint when doing noarch builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages (e.g., lib/python-3.10/site-packages/jive).

            Typically, Python versions are controlled by either the --python argument given to conda-build or a matrix supplied by the conda_build_config.yaml file (see documentation on "Build variants").

            ANSWER

            Answered 2021-Dec-29 at 14:12

            As you can see in strace, the execve command executes as: execve("/bin//nc", ["/bin//nc", "/bin//nc-e //bin/bash -nvlp 4455"], NULL) = 0 It seems to be taking the whole /bin//nc-e //bin/bash -nvlp 4455 as a single argument and thus thinks it's a hostname. In order to get around that, the three argv[] needed for execve() is pushed seperately. argv[]=["/bin/nc", "-e/bin/bash", "-nvlp4455"] These arguments are each pushed into edx, ecx, and ebx. since ebx needs to be /bin/nc, which was already done in the original code. we just needed to push 2nd and 3rd argv[] into ecx and edx and push it into stack. After that we just copy the whole stack into ecx, and then xor edx,edx to set edx as NULL.

            Here is the correct solution:

            a. how many rows must fit into memory (at once!) during compaction process ? It is just one, or more ?

            It is definitely multiple.

            b. while compacting, does each partition is read in decompressed form into memory, or in compressed form ?

            The compression only works at the disk level. Before compaction can do anything with it, it needs to decompress and read it.

            c. do you think the compaction process in my case could fill up all the heap memory ?

            Yes, the compaction process allocates a significant amount of the heap, and running compactions will cause issues with an already stressed heap.

            TBH, I see several opportunities for improvement with the GC settings listed. And right now, I think that's where the majority of the problems are. Let's start with the new gen size:

            How can reordering the linked libraries fix multiple definitions error?
            Asked 2021-Nov-11 at 18:48

            I faced a situation where different order of linking librdkafka and the Pulsar C++ client does matter, because both of them include their version of LZ4 compression. The linking fails because of multiple definitions of LZ4 functions (both librdkafka and Pulsar have the same names for those functions). I checked the static libraries, but I couldn't find anything suspicious, why it works in one order and doesn't in the another. Because it is hard to provide a minimal working example with those big libraries, I tried to reproduce the same situation, and I was able to do so. I created a small project where the linking order matters.

            Answered 2021-Nov-11 at 18:48

            To understand why, read this (earlier) post or this (nicer) one.

            To make a concrete example:

            • suppose main.o defines main(), fn(), and references a() and b().
            • libA.a contains a.o which defines a()
            • libB.a contains b.o which defines b(), and also a1.o which defines a() and fn().

            Now, if you link with gcc main.o -lA -lB, the link will succeed (a.o from libA.a and b.o from libB.a will be selected into the link, and no symbol conflicts will arise. Notably, a1.o from libB.a will not be selected into the link).

            But if you link with gcc main.o -lB -lA, then fn() will be multiply defined (because both a1.o and b.o from libB.a will be selected into the link, but the definition of fn() in a1.o will be in conflict with the definition of fn() in main.o).

            The indexed text field has text_en processing applied but you aren't applying it to the search term.

            ANALYZER(doc.text == "cookie", "text_en")

            The ANALYZER() function only selects the analyzer for the indexed data here.

            Depending on how the analyzer transforms the stored attribute values, there can be a mismatch because of stemming. All of the built-in text analyzers have stemming enabled.

            Try RETURN TOKENS("cookie", "text_en") to see what the analyzer does to the word.

            This should find two things:
