+Subject: [PATCH] Fix buffer size when formatting current date
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+gcc-8 and glibc-2.26.9000 reports this error:
+
+server/log.c:64:54: error: '%03d' directive output may be truncated writing between 3 and 11 bytes into a region of size between 0 and 49 [-Werror=format-truncation=]
+     snprintf(current_date, sizeof(current_date), "%s.%03d", buf, (int)(1000 * (time-seconds)));
+                                                      ^~~~
+
+This patch fixes two mistakes in the get_current_date() function:
+
+First strftime() can fail and then buf content is undefined. The patch
+makes sure the buf content is properly null-termited.
+
+Second if strftime() uses up the the whole buf array, no space will be
+left for appending miliseconds to current_date value in the subsequent
+snprintf() call. The patch increases current_data size so that things
+will always fit.
+
+In reality, all this should not matter because sane strftime() will
+return fixed-lenght string. But for all the cases and for sake of the
+compiler check this patch should be applied.
