Thread: pgsql: Extend sendFileWithContent() to handle custom content length in
Extend sendFileWithContent() to handle custom content length in basebackup.c sendFileWithContent() previously got the content length by using strlen(), assuming that the content given is always a string. Some patches are under discussion to pass binary contents to a base backup stream, where an arbitrary length needs to be given by the caller instead. The patch extends sendFileWithContent() to be able to handle this case, where len < 0 can be used to indicate an arbitrary length rather than rely on strlen() for the content length. A comment in sendFileWithContent() mentioned the backup_label file. However, this routine is used by more file types, like the tablespace map, so adjust it in passing.

Did you mean >= 0? - len = strlen(content); + if (len < 0) + len = strlen(content);
