got_get_repo_commits iterates over the commits and build a queue for later display. My previous memleak fix moved the TAILQ_INSERT_TAIL *before* the logic to exit the loop and so it broke the pagination. This fixes it by delaying the insertion into the queue, but also by moving the check for the "previous" button after we've opened the commit. ok tracey

This adds a new helper function `gotweb_link' that outputs an HTML link with the parameter correctly escaped. ok stsp@

reported by the W3C validator.

due to an error in the order of the arguments to fcgi_printf that I've introduced last time I touched gotweb_render_header the title is now "/" (or SCRIPT_NAME) and one assets (the safari pinned tab svg) is a funny URL :)

This guards against {mis,ab}use such as `tog < /dev/null`. ok plus fix from op@

keeping GOTWEBD_REPO_CACHESIZE * sizeof(struct cache_repo) inside the struct server makes it too large for imsg on some platforms (linux at least.) Instead, store a pointer and allocate the array when it's received on the child processes. ok stsp@

Avoid crashing by corrupting the pointer instead of writing to it and fix how sym is generated: it shouldn't include the '=' sign. ok / improvement tb@

We fail to release the memory for the nodes. To fix it however, we some consumer of the commit graph iterator need to be corrected: the returned pointer is safe to be used only up until the next iter_next call; save a copy it if it's needed afterwards too. ok stsp@

got_get_repo_commits mixes ids allocated on the heap and the one returned by the iter_next in the same variable, and then even attemp to free it. This is both a leak (we loose the pointer to the previously allocated id) and a possible invalid free since the object id pointer returned by the graph iterator is not to be passed to free(3). part of a bigger diff that's ok stsp@

Avoids leaking the node structure returned from add_node(). ok op@

Not everywhere getline does an implicit fflush, so we might end up not showing the prompt to the user. Spotted on alpine with muslc. ok Thomas Adams

while here drop the ternary too: if add_node succeeds `new_node' is non-NULL. ok stsp@

The tailq should ideally be empty when we reach got_commit_graph_close, but consumer code may exit the commit graph loop earlier. spotted by and ok stsp@
