[Darshan-users] Minor issues

[Harms, Kevin N.]

  Thank you for the bug reports.

> 1 - darshan-convert --annotate option : nb of character is limited to 6 for the metadata name

  This one is partially fixed in 2.2.8. The outcome might not be exactly desirable but when darshan-convert runs it appends the previous log version in the metadata. When adding this, there is a check if the metadata field would be exceeded and if so, it drops all other metadata and inserts only the prev_ver=x.yz data. Given that the current size of the metadata is limited to 64 characters, when we try to add prev_ver=2.02 to the existing metadata, the size will always be exceeded so no existing or new metadata will be inserted and only the prev_ver data will be present.

  I created a RT ticket for this: https://trac.mcs.anl.gov/projects/darshan/ticket/121

  I also committed a new code change that explicitly checks for overflow when appending user metadata.

  I opened an RT ticket and fixed this in revision 808 as well.
