With buildout raw underlying python interpreter does not have access to eggs with which gpython script was generated. See previous commit for details.
-
Kirill Smelkov authored
When buildout generates scripts, it injects the following prologue for them: #!/path/to/underlying/python import sys sys.path[0:0] = [ 'path/to/egg1', 'path/to/egg2', ... ] import SCRIPT SCRIPT.main() This way path to eggs are inserted before what was originally sys.path[0] and it breaks gpython check that `sys.path[0] == exedir`. -> Fix it by detecting buildout and in that case verifying that exedir is only present in sys.path, not located in sys.path[0].

We were appending whole $PYTHONPATH to pathv - a vector of path. But we should instead first split $PYTHONPATH by pathsep and extend pathv.

It is os.pathsep, which is ';' on Windows.

This continues 6b4990f6 (gpython: Fix pymain to properly setup sys.path[0]) - now we add test and verify that gpython actually sets sys.path in the same way as underlying python does: - don't add directory of gpython to sys.path - for `gpython file` add to sys.path[0] realpath(dir(file)) instead of dir(file) (see PySys_SetArgvEx for the reference, and else - if we do not make this change - added test breaks) - for `gpython -m mod` add to sys.path[0] realpath('') instead of ''. This exactly matches PY3 behaviour, while PY2 behaviour is to add '' However PY3 behaviour * is more sane, and * fixes test_defer_excchain_traceback on py27-gevent -> so we stick to it. Now all tests pass again.

GPython preimports golang and gevent, but until now, it was preimporting them before adjusting sys.path according to given -c/-m/file/... And this was leading to difference in behaviour with standard Python where e.g. `import golang` might result in different files loaded if e.g. golang/ is there on cwd and -c/-m was given. -> Rework gpython startup so that golang/gevent preimport happens after sys.path initialization. This fixes `tox -e py27-gevent` which was previously failing on test_defer_excchain_dump_pytest / test_defer_excchain_dump_ipython because dumped paths were different than expected ones. It, however, breaks test_defer_excchain_traceback on py27-gevent. -> We'll do more fixups to sys.path handling in the next patch which will fix that failure as well.

We'll need this in the next patch, where golang/gevent preimport will be moved from "before call to pymain", to "in between option parsing and interpreter start".

Reorganize parsiong of command line options so that first all options are parsed in a loop, and only after that a module/file/command is executed. This is needed as preparatory step for next patch: there we'll add support for -W, and `-W arg` can be given multiple times and has to be processed multiple times by creating multiple corresponding warning filters. Because those warning filters has to be applied uniformly to all 4 codepaths of execution phase (-m/-c/file/interactive console), it makes sense to move execution phase to after options parsing and inject common runtime preparatory steps right before that. This logic generally applies not only to -W, but to all other python options - e.g. -Q,-u,...

test_defer_excchain_dump_ipython was setting fresh env anew, thus not propagating $LD_PRELOAD that trun sets when libgolang was built with thread or address sanitizer. This way the subprocess spawned for IPython was failing with e.g. ==152924==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. -> Fix it by only adjusting environment for spawned IPython instead of setting it completely anew.

For example if test_defer_excchain_dump_ipython fails the output was: > assert retcode == 0 E assert 1 == 0 and it was unclear what was going on. Now the output is e.g. > assert retcode == 0, (stdout, stderr) E AssertionError: ('', '==152924==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

Until now gpython was always activating gevent on startup + adding goodness such as "always UTF-8 default encoding"; go, chan, b/u and friends available from builtin namespace, etc... While those goodness are sometimes useful on their own, it is not always appropriate to force a project to switch from threads to gevent. For this reason add a flag to select which runtime - either gevent or threads - gpython should use. gpython -Xgpython.runtime=gevent selects gevent, while gpython -Xgpython.runtime=threads selects threads. Gevent remains the default. It is also possible to specify desired runtime via $GPYTHON_RUNTIME environment variable. /reviewed-on nexedi/pygolang!5

This makes recovered exception object a good target to be explicitly chained into (PEP 3134) via .__cause__ because without .__traceback__ the information about where/how recovered exception originated would be lost. In turn, having recover to always return full exception info, should allow to use recover in "add error context"-style utilities. /reviewed-on: nexedi/pygolang!3

bb9a94c3 (golang: Teach defer to chain exceptions (PEP 3134) even on Python2) added integration patches for IPython and Pytest to properly dump tracebacks for chained exceptions even on Python2. However the functionality of patches was tested only manually. -> Add corresponding tests to verify how IPython and Pytest behaves when dumping tracebacks.

assertDoc normalizes paths in compared texts with the idea for etalon output to contain PYGOLANG instead of whatever actual path there will be when testing the package. This already works. However IPython, when dumping tracebacks, tries to shorten paths and abbreviate $HOME with ~ in them. This breaks normalization which misses to convert prefix of those paths into PYGOLANG. -> Fix it by teaching assertDoc to also handle paths that start with ~ and correctly normalize them. This will be needed in the next patch where we will add tests for how ipython and pytest dump tracebacks for chained exceptions.

qq is used to quote strings or byte-strings. The following example illustrates the problem we are currently hitting in zodbtools with Python3: >>> "hello %s" % qq("мир") 'hello "мир"' >>> b"hello %s" % qq("мир") Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' >>> "hello %s" % qq(b("мир")) 'hello "мир"' >>> b"hello %s" % qq(b("мир")) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'str' i.e. one way or another if type of format string and what qq returns do not match it creates a TypeError. We want qq(obj) to be useable with both string and bytestring format. For that let's teach qq to return special str- and bytes- derived types that know how to automatically convert to str->bytes and bytes->str via b/u correspondingly. This way formatting works whatever types combination it was for format and for qq, and the whole result has the same type as format. For now we teach only qq to use new types and don't generally expose _str and _unicode to be returned by b and u yet. However we might do so in the future after incrementally gaining a bit more experience. /proposed-for-review-on: nexedi/pygolang!1

i.e. unicode on py3 and bytes on py2. This makes it more likely to work for "format string %s ..." % qq(object) with format string being str and object of arbitrary type. However more on this topic in the next patch.

i.e. b(b(·)) and u(u(·)) are always identity. This property already holds and is easy to verify just by code review. However it might become less obvious once we start to tweak b and u. -> Add explicit test.

A build fix wrt gevent-1.5 + benchmarks for nogil go and channels.

Kirill Smelkov authored
Starting from gevent >= 1.5 '*.pxd' files for gevent API are no longer provided, at least in released gevent wheels. This broke pygolang: Error compiling Cython file: ------------------------------------------------------------ ... # Gevent runtime uses gevent's greenlets and semaphores. # When sema.acquire() blocks, gevent switches us from current to another greenlet. IF not PYPY: from gevent._greenlet cimport Greenlet ^ ------------------------------------------------------------ golang/runtime/_runtime_gevent.pyx:28:4: 'gevent/_greenlet.pxd' not found Since gevent upstream refuses to restore Cython level access[1], let's fix the build by using gevent bits via Python-level. Even when used via py import gevent-1.5 brings speed improvement compared to gevent-1.4 (used via cimport): (on i7@2.6GHz, gevent runtime) gevent-1.4 gevent-1.5 (cimport) (py import) name old time/op new time/op delta pyx_select_nogil 9.47µs ± 0% 8.74µs ± 0% -7.70% (p=0.000 n=10+9) pyx_go_nogil 14.3µs ± 1% 12.0µs ± 1% -16.52% (p=0.000 n=10+10) pyx_chan_nogil 7.10µs ± 1% 6.32µs ± 1% -10.89% (p=0.000 n=10+10) go 16.0µs ± 2% 13.4µs ± 1% -16.37% (p=0.000 n=10+10) chan 7.50µs ± 0% 6.79µs ± 0% -9.53% (p=0.000 n=10+10) select 10.8µs ± 1% 10.0µs ± 1% -6.78% (p=0.000 n=10+10) Using gevent-1.5 could have been even faster via cimport (it is still possible to compile and test against gevent installed in development mode via `pip install -e` because pxd files are there in gevent worktree and tarball): gevent-1.5 gevent-1.5 (py import) (cimport) name old time/op new time/op delta pyx_select_nogil 8.74µs ± 0% 7.90µs ± 1% -9.60% (p=0.000 n=9+10) pyx_go_nogil 12.0µs ± 1% 11.2µs ± 2% -6.35% (p=0.000 n=10+10) pyx_chan_nogil 6.32µs ± 1% 5.89µs ± 0% -6.80% (p=0.000 n=10+9) go 13.4µs ± 1% 12.4µs ± 1% -7.54% (p=0.000 n=10+9) chan 6.79µs ± 0% 6.42µs ± 0% -5.47% (p=0.000 n=10+10) select 10.0µs ± 1% 9.4µs ± 1% -6.39% (p=0.000 n=10+10) but we cannot use cimport to access gevent-1.5 universally, since pxd are not shipped in gevent wheel releases. In the future we might want to change plain version check into compile time check whether gevent/_greenlet.pxd is actually present or not and use faster access if yes. Requesting gevent to be installed in non-binary form might be also an option worth trying. However plain version check should be ok for now. [1] https://github.com/gevent/gevent/issues/1568
