gitup: load_file: problem reading /usr/src/contrib/llvm-project/libcxx/include/__string: Input/output error

[grahamperrin]

Briefly:

1. /usr/src might have been at 13.2.0 before the commands below
2. gitup release -t release/13.1.0 included removal of the /usr/src/contrib/llvm-project/libcxx/include/__string directory and its contents (lines 14035 and 14036 of the attached transcript), with an invitation to rerun gitup
3. gitup release -t release/13.1.0 failed with what might be a file-related error:

root@fuji:~ # gitup release -t release/13.1.0
# Scanning local repository...
# Host: git.freebsd.org
# Port: 443
# Repository Path: /src.git
# Target Directory: /usr/src
# Tag: release/13.1.0
# Have: 525ecfdad597980ea4cd59238e24c8530dbcd31d
# Want: fc952ac2212b121aa6eefc273f5960ec3e0a466d
# Action: pull
gitup: load_file: problem reading /usr/src/contrib/llvm-project/libcxx/include/__string: Input/output error
root@fuji:~ # 

error, __string.txt

Edge case, I suspect.

When I clone 525ecfdad5 and then pull fc952ac221, it goes through without any issue.

When I clone a previous commit (such as 3b5e5ce87b) then pull 525ecfdad5 and then pull fc952ac221, I get a different list of files to repair than what you're seeing and the repair never takes so this problem seems more widespread when reverting to earlier commits. This one might take me a while to fix.

If it helps …

contrib/llvm-project/libcxx/include/__string is:

• a non-directory file in releng/13.1 https://github.com/freebsd/freebsd-src/blob/releng/13.1/contrib/llvm-project/libcxx/include/__string
• a directory file in main https://github.com/freebsd/freebsd-src/tree/main/contrib/llvm-project/libcxx/include/__string

From https://github.com/johnmehr/gitup/issues/94#issue-1704546486:

… removal of the /usr/src/contrib/llvm-project/libcxx/include/__string directory and its contents (lines 14035 and 14036 of the attached transcript), …

Despite that, it still exists as a directory file:

root@fuji:~ # file /usr/src/contrib/llvm-project/libcxx/include/__string
/usr/src/contrib/llvm-project/libcxx/include/__string: directory
root@fuji:~ #

I just committed a potential fix for this issue. When you have a chance, could you please retrace your steps and see if the problem persists? Thank you!

[grahamperrin]

Thanks. Cloned, but (sorry) I need a hint of how to build and install from source.

If you cd into cloned directory and then execute make you should be able to run the updated code via ./gitup with your test parameters. Thanks!

[grahamperrin]

Sorry for taking so long.

… please retrace your steps and see if the problem persists? …

I think I retraced correctly, the problem is no longer reproducible. Thanks!

/usr/local/etc/gitup.conf temporarily edited to include these lines:

No worries!
