Keep clone files and oversized responses out of the cacheBryce Kwon-2/+6
The dumb transport reads files that already sit on the disk, so a pack copied into a slot cost that disk twice and the request a second write of every byte. A snapshot took a slot whatever its size, so a visitor naming distinct refs and ids could fill the cache root with archives. `cache-max-slot-size`, 64 MB unless set, now serves a larger response from the lock file and drops it, along with any expired copy it would have replaced.
Harden the request path, scan and error recoveryBryce Kwon-8/+10
Clean up the whole treeBryce Kwon-2/+1
Restyle the sources and fix the audit's findingsBryce Kwon-20/+21
Settle the names, types and layout of the sourcesBryce Kwon-1/+1
Reorganize into source, assets and librariesBryce Kwon-0/+0
The C sources move to source/, the served files to assets/, the bundled Git submodule to libraries/git and the filter scripts to extensions/. Everything the build generates now lands in build/, so a clean is a single remove and the tree stays clean.

Switch to exclusively using global ctxLukas Fleischer-3/+2
Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_print_http_headers() * cgit_print_docstart() * cgit_print_pageheader() Remove context parameter from all commands Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_get_cmd() * All cgit command functions. * cgit_clone_info() * cgit_clone_objects() * cgit_clone_head() * cgit_print_plain() * cgit_show_stats() In initialization routines, use the global context variable instead of passing a pointer around locally. Remove callback data parameter for cache slots This is no longer needed since the context is always read from the global context variable. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
use __attribute__ to catch printf format mistakesMark Lodato-0/+1
Use "__attribute__((format (printf,N,M)))", as is done in git, do catch mistakes in printf-style format strings. Signed-off-by: Mark Lodato <lodatom@gmail.com>
cache.h: export hash_str()Lars Hjemli-0/+2
This function will be reused to cache the result of tree scanning. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
Add page 'ls_cache'Lars Hjemli-0/+3
This new page will list all entries found in the current cache, which is useful when reviewing the new cache implementation. There are no links to the new page, but it's reachable by adding 'p=ls_cache' to any cgit url. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
Redesign the caching layerLars Hjemli-12/+21
The original caching layer in cgit has no upper bound on the number of concurrent cache entries, so when cgit is traversed by a spider (like the googlebot), the cache might end up filling your disk. Also, if any error occurs in the cache layer, no content is returned to the client. This patch redesigns the caching layer to avoid these flaws by * giving the cache a bound number of slots * disabling the cache for the current request when errors occur The cache size limit is implemented by hashing the querystring (the cache lookup key) and generating a cache filename based on this hash modulo the cache size. In order to detect hash collisions, the full lookup key (i.e. the querystring) is stored in the cache file (separated from its associated content by ascii 0). The cache filename is the reversed 8-digit hexadecimal representation of hash(key) % cache_size which should make the filesystem lookup pretty fast (if directory content is indexed/sorted); reversing the representation avoids the problem where all keys have equal prefix. There is a new config option, cache-size, which sets the upper bound for the cache. Default value for this option is 0, which has the same effect as setting nocache=1 (hence nocache is now deprecated). Included in this patch is also a new testfile which verifies that the new option works as intended. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
Add cache.hLars Hjemli-0/+23
The functions found in cache.c are only used by cgit.c, so there's no point in rebuilding all object files when the cache interface is changed. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
