Handling Broken Pipe Errors in Go
When working with network connections, it's common to encounter "broken pipe" errors. These occur when a remote host unexpectedly terminates the connection. In Go, these errors are typically returned from calls to io.Copy with a net.Conn (e.g., a TCP connection) as the destination.
Differentiating Broken Pipe Errors
To distinguish broken pipe errors from other types of errors, you can use the syscall package. The syscall.EPIPE constant represents the broken pipe error:
<code class="go">if err == syscall.EPIPE { // Handle the broken pipe error }</code>
Extracting the Error Number
Sometimes, you may want to retrieve the error number associated with the broken pipe error. This can be done using a type assertion:
<code class="go">if e, ok := err.(syscall.Errno); ok { errno := uintptr(e) // Use the errno for error handling }</code>
Ignoring Broken Pipe Errors
In some cases, you may want to ignore broken pipe errors. This can be useful when you expect the remote host to terminate the connection frequently. To ignore these errors, simply use the following code:
<code class="go">if err == syscall.EPIPE { // Ignore the error }</code>
Additional Precautions
While handling broken pipe errors is usually straightforward, it's important to avoid relying on them too heavily. In some cases, a broken pipe error can indicate a more serious issue that requires investigation.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
