Named pipes report file size as 0, which leads to reading the whole content into memory (0 is less than 64K). This adds additional check to make sure that the passed in path is not a named pipe, and in that case opts for the create-temp-file-to-gzip code path. When running on GitHub Actions infrastructure on `windows` node, named pipes can be created using `mkfifo` from MSYS2. In that case `fs.Stats`s `isFIFO()` returns `false`, and not `true` as expected. This case is detected by `process.platform` being `win32` and the passed file having length of 0. As a side note, when MSYS2's `mkfifo` is run, a pipe file is created: ``` prw-rw-rw- 1 User None 0 Mar 31 12:58 pipe ``` If `fs.stat` is invoked at this point `ENOENT` error will be thrown. As soon as the pipe is written to, this pipe file is replaced by two same- named files: ``` -rw-r--r-- 1 User None 0 Mar 31 13:00 pipe -rw-r--r-- 1 User None 0 Mar 31 13:00 pipe ``` And at this point `fs.stat` `isFIFO()` returns `false`. Even though the file acts as a named pipe. |
