But this part of the code is just a copy of the existing code. See:
- if (readBytes != sizeof(SnapBuild))
- {
- int save_errno = errno;
-
- CloseTransientFile(fd);
-
- if (readBytes < 0)
- {
- errno = save_errno;
- ereport(ERROR,
- (errcode_for_file_access(),
- errmsg("could not read file \"%s\": %m", path)));
- }
- else
- ereport(ERROR,
- (errcode(ERRCODE_DATA_CORRUPTED),
- errmsg("could not read file \"%s\": read %d of %zu",
- path, readBytes, sizeof(SnapBuild))));
- }
We just moved it to a separate function as the same code is being
duplicated to multiple places.
