    Having tests in Lib/test instead of inside the package makes it easier to grep the unittest package without grepping the tests. The Windows installer has an "install without tests" option which is easier to honour if the tests aren't in the package.

    However, currently all packages that have test *packages* have the tests in the package rather than inside Lib/test. (There are no test packages inside Lib/test.)

    Examples: email, distutils, ctypes, importlib, json, lib2to3, sqlite3

    I also maintain an external port of unittest from Python 3. This is unittest2-py3k. Moving the tests would make it *slightly* harder to keep this in sync. I'm moving to maintaining this port as a set of patches rather than a separate branch. These patches can be applied automatically to unittest from py3k head. unittest2-py3k will be built automatically by a script, so it isn't a big deal.

    3.1 should also be considered if the tests are moved. In theory this is not a bug fix so it shouldn't go in 3.1, but in practice it will make merging more difficult. This might not be a strong argument though, considering that 3.1 will accept only security fixes soon and only the few developers that work on unittest will be affected.

    The same is true for 2.7 though, and that is getting bug fixes. svnmerge would no longer work (and to making the change would mean moving the tests in a point release).

    Copy link

    abalkin commented Nov 29, 2010

    +0, and I think we should hear from the maintainers of the affected packages first. For packages that are also externally maintained moving tests out may cause inconvenience to the maintainer.

    For the email package I would be in favor of moving the tests to Lib/test. I've always found it a bit inconvenient that they are in Lib/email. After hearing of Michael's intent with unittest, and given the evolution of email5 into email5.1, I am also considering the possibility of packaging email6 (when I get to it!) as a patch set against email5, which would make this change less of an issue for email6 development.

    The 2.7 sync issue is a concern, but there are certainly precedents for differing file layouts between 3.x and 2.7. I'm willing myself to deal with this for email.

    Barry may have a different opinion.

    All of that said, this is a general enough issue that it may be appropriate to raise it on python-dev. Even if exceptions are made for individual packages, it would be good to agree on a general "best practices" rule for this for the stdlib.

    warsaw commented Nov 29, 2010

    grepping the code without the tests doesn't seem that compelling a use case to me, given that grep and find both provide options to prune directories. I do think that moving the tests out of the email package will make it harder to maintain and distribute as a separate package. However, if RDM thinks the burden won't be too high, and the advantages of a split outweigh the disadvantages, then I defer to him. I would still make a case for distributing email6 as a package available on Cheeseshop though, otherwise it just won't get much independent use until it's in the stdlib.

    Copy link

    Yes, a cheeseshop package is definitely part of the plan, I didn't mean to imply otherwise. It won't be hard to automate the packaging, and indeed I'll wind up doing that anyway even if the tests stay inside Lib/email.

    I will say that that I'm probably only +0.5 on this change...I like it from a consistency standpoint (heading toward all stdlib tests being in Lib/test) and it seems like it would make the job of packagers who desire a 'no tests' option easier. But things have been working fine as they are, which is why I'm not at a full +1 :).

    merwok commented Nov 29, 2010

    For distutils tests, I’m ±0. I don’t see any major drawback nor any major benefit. Tarek will decide.

    Copy link

    Of those, it makes the most sense to move the json tests to Lib/tests. Bob is not externally maintaining the 3.x version. It's all our now.

    Also, it looks like importlib is in a maintenance mode now.

    There is merit to keeping 2to3, ctypes, sqlite tests separate.

    Currently all of the documentation files are still under Doc so we should keep it that way and not move them under package directory trees.

    Copy link

    I have no issue with moving importlib into Lib/test as long as I can still run the tests with python3 -m test.importlib. I actually only put the tests in importlib.tests because that was common practice amongst newer packages in the stdlib.

    And just to prevent some rumour from perpetuating, importlib is not in maintenance mode. In fact the API was heavily reworked in 3.2 and I plan on exposing more of the API publicly in 3.3 and hopefully to bootstrap as well. The only thing you could think is in maintenance mode is importlib's Chesseshop package, but that's just for 2.x compatibility and for Django's benefit.

    Changing the title to reflect broader scope of this issue. Json tests were moved to Lib/test/json_tests in r86875.

    I believe that the complete list of test files still located outside of Lib/test are:


    That last is somewhat ironic since Michael opened the issue :).

    I'm considering working on some of the uncommitted patches for sqlite3, so I may take on moving those tests.

    Talked to Michael in IRC. He isn't particularly in favor of the move of the unittest tests, but doesn't object if someone else wants to do it. So, unassigning the issue from him.

    abalkin commented Jan 10, 2013

    ctypes/tests is within my area of interests and may prove to be one of the harder pieces. I'll try to move it and report the results. I have not worked with the rest, so unless it is truly trivial this will have to wait for another volunteer.

    Copy link

    I honestly don't see the point of moving tests around.

    Copy link

    Two reasons for collecting all of the tests in a single location:

    1. Facilitates test discovery
    2. It makes packaging of CPython easier for Linux distros that prefer to leave the tests out of the core package

    Patch attached to move sqlite3 tests under Lib/test, and remove Lib/test/

    Naming of files has been kept the same in the move from Lib/sqlite/test, to allow for easier merging of future patches.

    Naming of files has been kept the same in the move from
    Lib/sqlite/test, to allow for easier merging of future patches.

    This should be done with "hg mv" -- this will also allow to change the name while preserving the history if that's desirable.

    gmwils mannequin commented Feb 25, 2013

    The move will need to be done by someone with commit access. These patches came from using hg mv.

    After doing the move, there is some cleanup needed in each. These changes are included in the attached patches.

    @merwok that was my intent. As @vstinner pointed out earlier, with distutils on its way out I don't think it's worth the effort.

    I created PR #94145 for IDLE tests, even if @terryjreedy asked to not move them. I would prefer to move the tests, but I will follow Terry's decision, he maintains IDLE. I wrote a PR to see the consequences of moving tests. See my comment in the PR.

    Copy link

    Lib/idlelib/idle_test/ is the last Lib/ sub-directory which contains tests which are not under Lib/test/. I wait for @terryjreedy's last word on my PR #94145 to see if we move IDLE tests, or if we leave tests there and just close the issue.

    Note: This change is not effective on Microsoft Windows.
    Cookies can store sensitive information and should therefore be protected
    against unauthorized third parties. This is also described in issue #79096.
    The filesystem permissions are currently set to 644, everyone can read the
    file. This commit changes the permissions to 600, only the creater of the file
    can read and modify it. This improves security, because it reduces the attack
    surface. Now the attacker needs control of the user that created the cookie or
    a ways to circumvent the filesystems permissions.
    This change is backwards incompatible. Systems that rely on world-readable
    cookies will breake. However, one could argue that those are misconfigured in
    the first place.

    However, it omits that initial double slashes also aren't collapsed.
    Later, in documentation of ``, `PurePath.root`, and `` it mentions UNC but:
    - this abbreviation says nothing to a person who is unaware about existence of UNC (Wikipedia doesn't help either by [giving a disambiguation page](
    - it shows up only if a person needs to use a specific property or decides to fully learn what the module provides.
    For context, see the BPO entry.

    the _struct module to the cache to Struct objects to the Struct
    type back to the module. If _struct.Struct is not gc-tracked, that
    cycle is never collected.
    This PR makes _struct.Struct GC-tracked, and adds a regression test.

    I think we may be as close as we're going to get due to Terry's request to leave IDLE's tests in place.

    Thank you Brett. I opened #95069 for possibly moving IDLE tests someday (but not until after 3.11), in which I better explain the special issues I see.
