use struct strbuf instead of static buffers

2013-04-08T14:12:52Z

Use "struct strbuf" from Git to remove the limit on file path length. Notes on scan-tree: This is slightly involved since I decided to pass the strbuf into add_repo() and modify if whenever a new file name is required, which should avoid any extra allocations within that function. The pattern there is to append the filename, use it and then reset the buffer to its original length (retaining a trailing '/'). Notes on ui-snapshot: Since write_archive modifies the argv array passed to it we copy the argv_array values into a new array of char* and then free the original argv_array structure and the new array without worrying about what the values now look like.

Convert cgit_print_error to a variadic function

2013-04-08T14:11:29Z

This removes many uses of "fmt" which uses a fixed size static pool of fixed size buffers. Instead of relying on these, we now pass around argument lists for as long as possible before using a strbuf to render content of an arbitrary size. Signed-off-by: John Keeping

Fix out-of-bounds memory accesses with virtual_root=""

2013-04-08T13:59:46Z

The CGit configuration variable virtual_root is normalized so that it does not have a trailing '/' character, but it is allowed to be empty (the empty string and NULL have different meanings here) and there is code that is insufficiently cautious when checking if it ends in a '/': if (virtual_root[strlen(virtual_root) - 1] != '/') Clearly this check is redundant, but rather than simply removing it we get a slight efficiency improvement by switching the normalization so that the virtual_root variable always ends in '/'. Do this with a new "ensure_end" helper. Signed-off-by: John Keeping

Always #include corresponding .h in .c files

2013-04-08T13:45:34Z

While doing this, remove declarations from header files where the corresponding definition is declared "static" in order to avoid build errors. Also re-order existing headers in ui-*.c so that the file-specific header always comes immediately after "cgit.h", helping with future consistency. Signed-off-by: John Keeping

Return const char * in cgit_{httpscheme, hosturl, rooturl}()

2013-04-08T13:43:17Z

The return values of these functions are essentially constant and should never be modified. Note that this will introduce a compiler warning when we try to free the return value of any of these functions. However, given that all of these currently return statically allocated strings in some cases, they need to be refactored before this can be done anyway. Signed-off-by: Lukas Fleischer

ui-shared: squelch compiler warning.

2013-03-20T20:08:32Z

Since tail is initialized to 0, we will never get a warning on the last if statement, but recent gcc complains anyway. So, we initialize len as well. Future gcc versions should be able to optimize this out anyway.

ui-shared: fix return type of cgit_self_link

2013-03-20T19:21:17Z

cgit_self_link() is a void function but implements each case it handles by doing "return " which is not valid C; section 6.8.6.4 of C11 says: A return statement with an expression shall not appear in a function whose return type is void. Fix this by removing the return keywords and converting the final code block into an "else". Signed-off-by: John Keeping
