Mangled output in Copr logs

[voxik]

Observing Copr logs, there is corrupted output, presumably due to some encoding issues. Looking e.g. at libsbml build, the output contains:

/builddir/build/BUILD/libsbml-5.20.2/src/sbml/compress/zipfstream.cpp: In function ‘void* zipopen(const char*, const char*, int)’:
/builddir/build/BUILD/libsbml-5.20.2/src/sbml/compress/zipfstream.cpp:545:41: error: cannot convert ‘long unsigned int*’ to ‘uint32_t*’ {aka ‘unsigned int*’}
  545 |     filetime(filenameinzip,&zi.tmz_date,&zi.dosDate);
      |                                         ^~~~~~~~~~~
      |                                         |
      |                                         long unsigned int*
/builddir/build/BUILD/libsbml-5.20.2/src/sbml/compress/zipfstream.cpp:97:64: note:   initializing argument 3 of ‘long unsigned int filetime(const char*, tm_zip*, uint32_t*)’
   97 | unsigned long filetime(const char* f, tm_zip* tmzip, uint32_t* dt);
      |                                                      ~~~~~~~~~~^~

Please note the ’ sequences. Comparing with Koji, where the output is fine:

/builddir/build/BUILD/libsbml-5.20.2/src/sbml/compress/zipfstream.cpp: In function ‘void* zipopen(const char*, const char*, int)’:
/builddir/build/BUILD/libsbml-5.20.2/src/sbml/compress/zipfstream.cpp:545:41: error: cannot convert ‘long unsigned int*’ to ‘uint32_t*’ {aka ‘unsigned int*’}
  545 |     filetime(filenameinzip,&zi.tmz_date,&zi.dosDate);
      |                                         ^~~~~~~~~~~
      |                                         |
      |                                         long unsigned int*

   97 | unsigned long filetime(const char* f, tm_zip* tmzip, uint32_t* dt);
      |                                                      ~~~~~~~~~~^~

I know that with RPM 4.19 the default encoding changed from C to C.UTF-8. Can it be the reason for the issue?

P.S. sorry if the links to the logs disappeared by the time you are looking at the ticket.

[voxik]

My guess is that gcc is using typographic quotes with C.UTF-8, while using straight quotes for C encoding. And Copr handles the logs as C encoded.

Thank you for the report @voxik, I am uploading the log here so it doesn't get lost after Christmas - 06771727-builder-live.log.gz

'll often use a 'lazy' debug tool in .spec work, namely dropping a tree ./ into %prep, %build, etc., to see/poke in builder-live.log.gz

when I do, the display fonts -- only in the tree cmd output used at COPR online -- are munged. e.g., in a .spec

%prep
...
cd %{_builddir}
tree ./
...

in builder live log,

+ tree ./

when i build locally, no such issue -- fonts display as normal. fwiw, i've never noticed (yet) any font mangling other than with tree

attaching builder-live.log.gz

This issue appears t apply to any text file served by Copr. I noticed strange characters during package review. However, when downloading the file in question and viewing it locally (vim) it looked fine.

Here's a spec file that displays the first three words as We can’t run, whereas locally it displays correctly as We can’t run.

[praiskup]

This doesn't seem to be caused by CDN because even the source file is mangled.
