build.log
Seconding this bug, just ran into it after an 'emerge --sync' and 'emerge -uDNav world' today. Interesting note:
On a whim I restarted emerge ("emerge -av --resume"). Resuming sets a different build order: pycparser now 2nd item in set, rebuild of dev-python/traceback2-1.4.0 comes first. traceback2 succeeds, pycparser fails again.
Resume again, pycparser comes first. I expect it to fail -- but it succeeds.
traceback2 doesn't include a 'lextab' component, and no other python changes were made in between, so not sure why this worked.
So, to summarize:
--- Event 1 ---
'emerge -uDNav world' fails on upgrade of dev-python/pycparser-2.20 (from dev-python/pycparser-2.19-r1), with:
warning: build_py: byte-compiling is disabled, skipping.
Traceback (most recent call last):
File "_build_tables.py", line 35, in <module>
import lextab
ModuleNotFoundError: No module named 'lextab'
--- Event 2 ---
'emerge --resume' starts with rebuild of dev-python/traceback2-1.4.0, followed by upgrade to dev-python/pycparser-2.20. traceback2 succeeds, but pycparser still fails:
warning: build_py: byte-compiling is disabled, skipping.
Traceback (most recent call last):
File "_build_tables.py", line 35, in <module>
import lextab
ModuleNotFoundError: No module named 'lextab'
--- Event 3 ---
'emerge --resume' starts with upgrade to dev-python/pycparser-2.20, and succeeds.
Same error today with pycparser-2.20, by the way. Any progress on this? Like OP, same error today, different machine than my previous report. This particular machine didn't have traceback2 installed, which saved my emerge --update last week. 'emerge --resume'ing wasn't getting me anywhere. So on a whim I installed dev-python/traceback2. It pulled in dev-python/pbr-4.2.0-r1, dev-python/linecache2-1.0.0, and dev-python/traceback2-1.4.0. Voila! dev-python/pycparser-2.20 now emerges. When I ran 'emerge --resume --skipfirst' pycparser completed without error, so apparently something does have to be emerge first for it to be able to find lextab. 'equery b /usr/lib64/python3.7/site-packages/pycparser/lextab.py' doesn't return anything, nor for the same file under …/python3.8/…, so I'm not sure what installed it. But neither of those files was there yesterday, so I'd guess that pycparser depends on whatever that package is being installed with the same python versions used to build pycparser. Same error on dev-python/pycparser-2.20-r1 today. emerging this a second time and it emerged fine... ERROR: dev-python/pycparser-2.20-r1::gentoo failed (compile phase) ModuleNotFoundError: No module named 'lextab' It is obvious that the problem is in 'pycparser' itself: # equery belongs /usr/lib/python3.7/site-packages/pycparser/lextab.py * Searching for /usr/lib/python3.7/site-packages/pycparser/lextab.py ... dev-python/pycparser-2.20 (/usr/lib/python3.7/site-packages/pycparser/lextab.py) I had seen similar issue in different project. It was caused by incomplete dependencies specification. Build system tried to use item which was not built yet. As workaround we disabled parallel build in that project. Build for 'dev-python/pycparser-2.20-r1' launched with 'emerge --jobs 1' finished successfully. emerged this the 2nd time and it build. concurrency issue, somehow dependency isn't expressed same here for pycparser-2.20-python3_9 not sure if setup.py uses make, in any case, buildlog is here: https://bootstrap.prefix.bitzolder.nl/results/x86_64-apple-darwin17/20211120/portage/dev-python/pycparser-2.20-r1/temp/build.log FWIW: seems fixed in 2.21 (In reply to Fabian Groffen from comment #13) > FWIW: seems fixed in 2.21 still happens with 2.21 pycparser-2.21 is still failing for missing module. 'emerge --jobs=1 pucparser' works. > pycparser-2.21 is still failing for missing module. Also failing pycparser-2.21-r1 > 'emerge --jobs=1 pucparser' works. Works for me too. Thanks! Cleanup of bugs open for old versions. On a new install of Gentoo today I ran into this exact problem. I pushed the eemrge until pycparser (2-21-r1) was the first in the --resume list then used --skipfirst to bypass it. i let another 15 or so packages install (this was part of adding gnuradio, soapysdr, and kicad to my system so 80pkgs or so in total). End result: in another terminal, while the rest of the ebuild was motoring on, I did 'emerge -O1 pycparser' and it built and installed without incident. The trouble was definitely rooted in not being able to build lextab. This bug persists. Issue persists. Hit on a system upgrade.

This does not work for me: emerge --jobs=1 pycparser But oddly, this did: emerge -O1 pycparser (In reply to Gary E. Miller from comment #24) > This does not work for me: > > emerge --jobs=1 pycparser --jobs=1 controls emerge-level parallelism so it shouldn't make a difference, it's not the same as MAKEOPTS. > > But oddly, this did: > > emerge -O1 pycparser That shouldn't make a difference to emerging pycparser by itself. It's more that it's a race and this happened to work. If you tried it in a loop, I suspect one would eventually fail.

If you tried it in a loop, I > suspect one would eventually fail. You are correct I tried it 5 times, and it failed 4 times. I'm looking into it. That said, I still can't reproduce. I've put it in a loop now, and few runs passed with no problem so far. I've inspected the code and there doesn't seem to be anything wrong with it. FWICS lex() should either read existing lextab (which doesn't exist, so that fails) or write one reliably, using a context manager. Nothing random to happen there. So far my only guess is that Python has some import caching, and it doesn't "notice" that lextab.py appeared. That said, if I can't reproduce it I'm going to need your help debugging it.

Debugging patch
Ok, I think technically ply could fail to write lextab and then put the error in some error log that probably isn't printed.
Could you please put the attached patch into /etc/portage/patches/dev-python/pycparser/ and attach/paste the output when you manage to make it fail again?
Note that this will only work with -r1. I'm going to push -r2 that unbundles ply shortly, and the patch will not apply to it. Please test with -r1.

I called the patch: /etc/portage/patches/dev-python/pycparser/patch701878 Looking at the build log, I do not see it being applied. What did I do wrong? (In reply to Gary E. Miller from comment #32) > I called the patch: > > /etc/portage/patches/dev-python/pycparser/patch701878 > > Looking at the build log, I do not see it being applied. What did I do > wrong? Ah, you have to give it a .patch (or .diff suffix) or Portage will ignore it, I think. I renamed it: /etc/portage/patches/dev-python/pycparser/print.patch And it seems to apply now. Running 10 times, got 10 failures. Build log attached. Created attachment 854018 [details]

Just for fun I tried: nice -n 20 emerge -1 pycparser And: ionice emerge -1 pycparser Hoping to jiggle any latency effects, but no change. Also no effect: MAKEOPTS="-j1" Now that's weird. I suppose: find /var/tmp/portage/dev-python/pycparser-2.21-r1/work/pycparser-2.21 -name lextab.py yields nothing? Can you try cloning the upstream git repo and testing there? i.e.: git clone https://github.com/eliben/pycparser/ cd pycparser python -m build -nw ? If that succeeds, you may want to try release_v2.21 tag too. (In reply to Michał Górny from comment #37) > Now that's weird.

The only things there are gpsd and ntpsec. I wipe site-packages frequently. Python will look there, then continue it's normal searsh for modules. Please test if the package fails to build with PYTHONPATH unset. (In reply to Michał Górny from comment #58) > Please test if the package fails to build with PYTHONPATH unset. As expected, unsetting PYTHONPATH has no effect. I'm afraid I have no clue what's happening here. FWICS things work when you call _build_tables.py manually but they don't when setup.py calls it (via build frontend). Could you perhaps could try a few times to remove lextab.py, then run _build_tables.py again and see if it perhaps fails 1 out of N attempts?

Ok, so apparently it doesn't even try to open it afterwards.
Could you apply the following patch to your git checkout and try:
rm lextab.py ; python -B _build_tables.py
again? It should print a bunch of import-related variables.
Created attachment 854658 [details]
rm lextab.py ; strace -o trace.log python -B _build_tables.py
strace log of failure.
Another idea: stat . ; rm lextab.py ; stat . ; python -B _build_tables.py ; stat .

You are using only second-precision timestamps, so what basically happens is: 1. You remove the file, so mtime of the directory is set to the current second. 2. The Python script writes lextab.py within the same second, so mtime stays the same. 3. Python determines mtime didn't change, so doesn't update the cache. I can't reproduce it because I have sub-second timestamps. Ideally, you could confirm it by doing something like: rm lextab.py ; touch -r / . ; python -B _build_tables.py Since it's resetting mtime of the current directory prior to starting the script, Python should start invalidating the cache.

Odd, how do I see the timestamp size? How do I get sub-seconds on ext4? > Ideally, you > could confirm it by doing something like: > > rm lextab.py ; touch -r / . ; python -B _build_tables.py > > Since it's resetting mtime of the current directory prior to starting the > script, Python should start invalidating the cache. Yeah, that always works. Nice touch. Created attachment 854660 [details, diff]

Ok, as a final request: could you `git checkout .` to undo our changes, reproduce the failure again, then apply the attached patch and confirm that it works with it applied? If it does, I'm going to send it upstream and have this resolved once and for all.

How many times have I heard that?? :-) re improving accuracy: I can't find much yet. I found e.g. https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond?rq=1 but nobody seems to talk about how to actually fix it or what causes it. Is it a really old ext4 partition or perhaps with tweaked parameters at creation time? (In reply to Sam James from comment #75) > re improving accuracy: I can't find much yet.

Is it a really old ext4 partition or perhaps with tweaked > parameters at creation time? I found there is the old ext2 and ext3 compatable ext4 inode, and a newer one, that is 2x the size, that implements the sub-seconds. The volume was created 2018-11-14. Must be before the change? But I have much older that seem unaffected. Here is the caps for subseconds ext4: capabilities: multi journaled extended_attributes large_files huge_files dir_nlink recover 64bit extents ext4 ext2 initialized And non-subseconds: capabilities: journaled extended_attributes large_files huge_files dir_nlink recover 64bit extents ext4 ext2 initialized The same, except for multi. But that is off topic, I'll work on that. Let's get this 3+ year old bug fixed! Hot on the trail! For ext4 to support nanoseconds, it needs a larger inode. The is controlled by the extra_isize feature, present since Linux 2.6.28. Oddly, dumpe2fs shows extra_isize on the seconds only ext4: Filesystem features: has_journal ext_attr dir_index filetype needs_recovery meta_bg extent 64bit flex_bg sparse_super large_file huge_file uninit_bg dir_nl ink extra_isize On the ext that has working sub-seconds: Filesystem features: has_journal ext_attr resize_inode dir_index filetype n eeds_recovery extent 64bit flex_bg sparse_super large_file huge_file dir_nlink e xtra_isize metadata_csum Both have identical /etc/mke2fs.conf No hookah smoking caterpillars yet.

The counterpart to that is "why do I have to rebuild things when nothing changed?" We usually only revbump if the installed files change or dependencies. |
