Ramsay Jones	84d32bf767	sparse: Fix mingw_main() argument number/type errors Sparse issues 68 errors (two errors for each main() function) such as the following: SP git.c git.c:510:5: error: too many arguments for function mingw_main git.c:510:5: error: symbol 'mingw_main' redeclared with different type \ (originally declared at git.c:510) - different argument counts The errors are caused by the 'main' macro used by the MinGW build to provide a replacement main() function. The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char ' but argument is of \ type 'char ' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Jeff King	bfae342c97	remote-testsvn: fix unitialized variable In remote-test-svn, there is a parse_rev_note function to parse lines of the form "Revision-number" from notes. If it finds such a line and parses it, it returns 0, copying the value into a "struct rev_note". If it finds an entry that is garbled or out of range, it returns -1 to signal an error. However, if it does not find any "Revision-number" line at all, it returns success but does not put anything into the rev_note. So upon a successful return, the rev_note may or may not be initialized, and the caller has no way of knowing. gcc does not usually catch the use of the unitialized variable because the conditional assignment happens in a separate function from the point of use. However, when compiling with -O3, gcc will inline parse_rev_note and notice the problem. We can fix it by returning "-1" when no note is found (so on a zero return, we always found a valid value).

Florian Achleitner	5bfc76b5b2	remote-svn: add marks-file regeneration fast-import mark files are stored outside the object database and are therefore not fetched and can be lost somehow else. marks provide a svn revision --> git sha1 mapping, while the notes that are attached to each commit when it is imported provide a git sha1 --> svn revision mapping. If the marks file is not available or not plausible, regenerate it by walking through the notes tree. , i.e. The plausibility check tests if the highest revision in the marks file matches the revision of the top ref. It doesn't ensure that the mark file is completely correct. This could only be done with an effort equal to unconditional regeneration.

Florian Achleitner	8e43a1d010	remote-svn: add incremental import Search for a note attached to the ref to update and read it's 'Revision-number:'-line. Start import from the next svn revision. If there is no next revision in the svn repo, svnrdump terminates with a message on stderr an non-zero return value. This looks a little weird, but there is no other way to know whether there is a new revision in the svn repo. On the start of an incremental import, the parent of the first commit in the fast-import stream is set to the branch name to update. All following commits specify their parent by a mark number. Previous mark files are currently not reused.

Florian Achleitner	f6529de9f4	Allow reading svn dumps from files via file:// urls For testing as well as for importing large, already available dumps, it's useful to bypass svnrdump and replay the svndump from a file directly. Add support for file:// urls in the remote url, e.g. svn::file:///path/to/dump When the remote helper finds an url starting with file:// it tries to open that file instead of invoking svnrdump.

Florian Achleitner	68f64ff8b4	Implement a remote helper for svn in C Enable basic fetching from subversion repositories. When processing remote URLs starting with testsvn::, git invokes this remote-helper. It starts svnrdump to extract revisions from the subversion repository in the 'dump file format', and converts them to a git-fast-import stream using the functions of vcs-svn/. Imported refs are created in a private namespace at refs/svn/<remote-name>/master. The revision history is imported linearly (no branch detection) and completely, i.e. from revision 0 to HEAD. The 'bidi-import' capability is used. The remote-helper expects data from fast-import on its stdin. It buffers a batch of 'import' command lines in a string_list before starting to process them.
