[Bug 1373726] Re: Config file buffer limit

[Heinrich Schuchardt]

With the ~/.ltrace.conf described above the problem is reproducible on
Ubuntu 21.04, 0.7.3-6.1ubuntu2.

$ ltrace ls
/home/user/.ltrace.conf:1: error: expected ')', got '
/home/user/.ltrace.conf:2: error: unknown type around ', EMSGSIZE=90, EPROTOTYPE=91, ENOPROTOOPT=92, EPROTONOSUPPORT=93, ESOCKTNOSUPPORT=94, EOPNOTSUPP=95, EPFNO

To which upstream do you relate? Please, provide a link to the upstream
patch.

Best regards

Heinrich

Title:
  Config file buffer limit

Status in ltrace package in Ubuntu:
  Confirmed

Bug description:
  The routine read_config_file is still using a statically sized buffer.
  Almost two years ago this was fixed in upstream.

  This breaks when using very long config file lines.  For example,
  trying to set an enum for all enumerated error numbers in errno (see
  below).

  daefa4a - Use getline instead of static buffer in read_config_file (1
  year, 7 months ago) - Petr Machata

  To reproduce, create a file named ~/.ltrace.conf with the following
  line:

  typedef errno=enum ( EPERM=1, ENOENT=2, ESRCH=3, EINTR=4, EIO=5,
  ENXIO=6, E2BIG=7, ENOEXEC=8, EBADF=9, ECHILD=10, EAGAIN=11, ENOMEM=12,
