|\ \ | |/ |/| | | | | | | | | | | | | "git bisect" makes an internal call to "git diff-tree" when bisection finds the culprit, but this call did not initialize the data structure to pass to the diff-tree API correctly. * jk/bisect-show-tree: bisect: always call setup_revisions after init_revisions
| * bisect: always call setup_revisions after init_revisionsJeff King2016-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | init_revisions() initializes the rev_info struct to default values, and setup_revisions() parses any command-line arguments and finalizes the struct. In e22278c (bisect: display first bad commit without forking a new process, 2009-05-28), a show_diff_tree() was added that calls the former but not the latter. It doesn't have any arguments to parse, but it still should do the finalizing step. This may have caused other minor bugs over the years, but it became much more prominent after fe37a9c (pretty: allow tweaking tabwidth in --expand-tabs, 2016-03-29). That leaves the expected tab width as "-1", rather than the true default of "8". When we see a commit with tabs to be expanded, we end up trying to add (size_t)-1 spaces to a strbuf, which complains about the integer overflow. The fix is easy: just call setup_revisions() with no arguments. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | | strbuf: introduce strbuf_getline_{lf,nul}()Junio C Hamano2016-01-15
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The strbuf_getline() interface allows a byte other than LF or NUL as the line terminator, but this is only because I wrote these codepaths anticipating that there might be a value other than NUL and LF that could be useful when I introduced line_termination long time ago. No useful caller that uses other value has emerged. By now, it is clear that the interface is overly broad without a good reason. Many codepaths have hardcoded preference to read either LF terminated or NUL terminated records from their input, and then call strbuf_getline() with LF or NUL as the third parameter. This step introduces two thin wrappers around strbuf_getline(), namely, strbuf_getline_lf() and strbuf_getline_nul(), and mechanically rewrites these call sites to call either one of them. The changes contained in this patch are: * introduction of these two functions in strbuf.[ch] * mechanical conversion of all callers to strbuf_getline() with either '\n' or '\0' as the third parameter to instead call the respective thin wrapper. After this step, output from "git grep 'strbuf_getline('" would become a lot smaller. An interim goal of this series is to make this an empty set, so that we can have strbuf_getline_crlf() take over the shorter name strbuf_getline(). Signed-off-by: Junio C Hamano <gitster@pobox.com>

This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The log-tree code keeps a "struct decoration" hash to show text decorations for each commit during log traversals. It makes this available to other files by providing global access to the hash. This can result in other code adding entries that do not conform to what log-tree expects. For example, the bisect code adds its own "dist" decorations to be shown. Originally the bisect code was correct, but when the name_decoration code grew a new field in eb3005e (commit.h: add 'type' to struct name_decoration, 2010-06-19), the bisect code was not updated. As a result, the log-tree code can access uninitialized memory and even segfault. We can fix this by making name_decoration's adding function public. If all callers use it, then any changes to struct initialization only need to happen in one place (and because the members come in as parameters, the compiler can notice a caller who does not supply enough information). As a bonus, this also means that the decoration hashes created by the bisect code will use less memory (previously we over-allocated space for the distance integer, but now we format it into a temporary buffer and copy it to the final flex-array).
