reduce delta cache size to avoid running out of memory on large pack files As reported by Jerome Kasper, got-index-pack would run out of memory while cloning projects like LLVM or the Linux kernel. The delta cache was pushed to its maximum size limit of ~2GB, which is much higher than the default user data limit on OpenBSD. Set the delta cache size limits to values which should result in the cache limiting itself to 128MB or less.

add dedicated compilation flag for the delta cache, separate from object cache

zero-initialize all of struct got_deflate_buf in got_deflate_init() Fixes a potential bogus free on error. got_deflate_end() relies on zb.flags to be initialized. It will try to free a bogus zb.outbuf pointer if zb.flags happens to set by uninitialized stack memory while we are calling got_deflate_end() in an error path.

zero-initialize all of struct got_inflate_buf in got_inflate_init() Fixes a potential bogus free on error. got_inflate_end() relies on zb.flags to be initialized.

fix free() of wrong address in gotweb's parse.y Found by sthen via ports-gcc: gotweb/parse.y:504:3: warning: attempt to free a non-heap object 'file'

remove casts which make older gcc versions unhappy ../lib/diffreg.c:44: error: initializer element is not constant ../lib/diffreg.c:51: error: initializer element is not constant ../lib/diffreg.c:59: error: initializer element is not constant ../lib/diffreg.c:66: error: initializer element is not constant reported by Red on Libera IRC, and by sthen@ who pointed out such failures appearing in landry's sparc64 bulk build logs.

fix reference counting of raw objects opened via privsep helpers Such objects were never closed, resulting in memory and file descriptor leaks.
