gotwebd: fix double free in gotweb_process_request don't free the querystring, it's already done later by fcgi_celanup_request. ok tracey@

tog: add missing checks for NULL pointers in log view state ok jamsek

tog: don't block when processing log view 'G' key map As per stsp's TODO item, make tog respond to key presses while "loading..." history. Initial testing in src.git appears to work as intended. ok stsp@

tog: fix delayed tree index update If a child blame view has been opened, halfdelay() is reset to a 1 second refresh rate, so the index in the header lags behind subtree navigation as we set the index based on the selected tree entry, which isn't updated till that refresh cycle completes. Don't wait for the selected_entry to update; instead, compute the index from the first displayed entry and the currently selected line index. improved by and ok stsp@

tog: move all 'G' logic into log_move_cursor_down() Previously, we only handled 'G' in log_move_cursor_down() when all commits had not yet been loaded; move the case where all commits are already loaded into this routine too, and simplify by handling both cases the same. This change was prompted by Mikhail's observation of a redundant assignment in the previous 'G' handling in log_move_cursor_down(). ok stsp@

tog: fix log 'd' keymap when last commit is displayed When at the end of the log view such that the currently selected line is greater than nlines/2, add--don't assign--the page down value to the selected index so we don't jump up when the user expects tog to scroll down. While here, rework log page down logic for a smoother UX in horizontal split mode by moving the selection cursor down rather than scrolling when 'd' or 'f' is entered if the last commit is already on screen. ok stsp@

fix unused variable, function definition warnings for clang 15

convert gotwebd.conf "bind interface IP/iface" to "listen on IP/iface" ok kn, tracey

gotwebd: fix alternate colors in tree entries it was broken in 7ecc454 because now we're emitting tags with multiple `class' attributes (by mistake) and only the first one is used. However, instead of fixing the HTML `class' attribute, use a CSS selector to alternate the background colors. ok tracey@

gotwebd: add a some buffering This adds some buffering to fcgi_gen_binary_response so that we don't end up sending too many (very) small fastcgi records. While here also make fcgi_send_response non-void and make its errors "sticky". ok tracey@

gotwebd: switch some HTML IDs to classes HTML IDs are meant to be unique across the page. While here fix two small errors in the generated HTML (one missing closing div and one extra.) ok tracey@

gotwebd: wrap __packed around __attribute__ Needed for -portability reasons. OK op@

remove the last remaining use of sin_len from gotwebd I don't think this assignment to sin_len is needed at all, because sin_len is already being set via got_sockaddr_inet[6]_init() during the configuration stage. Tested successfully on both fcgi socket types (unix / tcp).

tog: drop regex for line types to colour the diff view ok stsp@
