* Fix various sparse warnings in the git source codeLinus Torvalds2009-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

* imap.preformattedHTML to tell Thunderbird to send non-flowed textJeremy White2009-02-151-0/+53
| | | | | | | | | | | | | | | Many e-mail based development communities require non-flowed text to carry patches to prevent whitespaces from getting mangled, but there is no easy way to tell Thunderbird MUA not to use format=flowed, unless you configure it to do so unconditionally for all outgoing mails. A workaround for users who use git-imap-send is to wrap the patch in "pre" element in the draft folder as an HTML message, and tell Thunderbird to send "text only". Thunderbird turns such a message into a non-flowed plain text when sending it out, which is what we want for patch e-mails.

* Add calls to git_extract_argv0_path() in programs that call git_config_*Steffen Prohaska2009-01-261-0/+3
| | | | | | | | | | | | Programs that use git_config need to find the global configuration. When runtime prefix computation is enabled, this requires that git_extract_argv0_path() is called early in the program's main(). This commit adds the necessary calls.

* Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializerBrandon Casey2008-10-121-2/+1
| | | | | | | | | | | Many call sites use strbuf_init(&foo, 0) to initialize local strbuf variable "foo" which has not been accessed since its declaration. These can be replaced with a static initialization using the STRBUF_INIT macro which is just as readable, saves a function call, and takes up fewer lines.

* imap-send.c: more style fixesJunio C Hamano2008-07-251-114/+111
| | | | | | | | | | | | | | | | | | | | | | | The previous one sqeezed unnecessary whitespaces and joined function type and name in the definition split across lines. This patch further fixes many remaining style issues: - We are not particularly fond of typedef to hide the underlying struct definitions. - Asterisk comes next variable, i.e. "type *var", not "type * var" nor "type* var". - Casting to pointer to a type is "(type *)", not "(type*)". - An open brace comes on the same line as closing parenthesis of "if (...)" condition; "else" comes on the same line as closing brace of its corresponding "if (...) {". - Avoid single liner "if (...) <stmt>;"; they should be on two separate lines.

| | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables.

* Don't force imap.host to be set when imap.tunnel is setJeff King2008-04-221-2/+5
| | | | | | | | | | | | | | | | | | The documentation for git-imap-send suggests a tunnel setting such as Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null" which works wonderfully and doesn't require a username, password or port setting. However, git-imap-send currently requires that the imap.host variable be set in the config even when it was unused. This patch changes imap-send to only require that the imap.host setting is set if imap.tunnel is not set. Otherwise, server.host is set to "tunnel" for reporting purposes.

| | | | | | | | | | | | | If no imap host is specified in the git config, git imap-send used to try to lookup a null pointer through gethostbyname(), causing a segfault.

* Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-221-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

* strbuf change: be sure ->buf is never ever NULL.Pierre Habouzit2007-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | For that purpose, the ->buf is always initialized with a char * buf living in the strbuf module. It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

| | | | | | | | | | | | | | | * drop nfasprintf. * move nfvasprintf into imap-send.c back, and let it work on a 8k buffer, and die() in case of overflow. It should be enough for imap commands, if someone cares about imap-send, he's welcomed to fix it properly. * replace nfvasprintf use in merge-recursive with a copy of the strbuf_addf logic, it's one place, we'll live with it. To ease the change, output_buffer string list is replaced with a strbuf ;) * rework trace.c to call vsnprintf itself. It's used to format strerror()s and git command names, it should never be more than a few octets long, let it work on a 8k static buffer with vsnprintf or die loudly.

* Rename imap-send's internal info/warn functions.Shawn O. Pearce2006-12-211-12/+12
| | | | | | | | | | | | | | | Because I am about to introduce a global warn() function (much like the global error function) this global declaration would conflict with the one supplied by imap-send. Further since imap-send's warn function output depends on its Quiet setting we cannot simply remove its internal definition and use the forthcoming global one. So refactor warn() -> imap_warn() and info() -> imap_info() (the latter was done just to be consistent in naming). Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>

Note that this behavior is not compatible with the previous one. We also trace whole messages using one write(2) call to make sure messages from processes do net get mixed up in the middle.
