I have to be honest: this commit message (including the subject) left me quite puzzled as to the intent of this patch. Maybe something like this would have spared me that puzzlement: Avoid unnecessary offset_1st_component() when prefixing filenames In the abspath_part_inside_repo() function that is called somewhere deep in the call-chain when prefixing paths, we calculate the offset of the first component, but under certain circumstances, the result is not even used. This patch changes the code to avoid that. If you also have a background story that motivated you to work on this patch (for example, if you hit a huge performance bottleneck with some tool that fed thousands of absolute paths to Git that needed to be turned into paths relative to the worktree's top-level directory), I would definitely put that into the commit message, too, if I were you. > diff --git a/setup.c b/setup.c > index 8cc34186c..1ce0189fa 100644 > --- a/setup.c > +++ b/setup.c > @@ -35,7 +35,6 @@ static int abspath_part_inside_repo(char *path) > return -1; > wtlen = strlen(work_tree); > len = strlen(path); > - off = offset_1st_component(path); > > /* check if work tree is already the prefix */ > if (wtlen <= len && !strncmp(path, work_tree, wtlen)) { > @@ -49,6 +48,8 @@ static int abspath_part_inside_repo(char *path) > } > /* work tree might match beginning of a symlink to work tree */ > off = wtlen; > + } else { > + off = offset_1st_component(path); > } Up until recently, we encouraged dropping the curly brackets from single-line statements, but apparently that changed. It is now no longer clear, and often left to the taste of the contributor. But not always. Sometimes we start a beautiful thread discussion the pros and cons of curly brackets in the middle of patch review, and drop altogether reviewing the actual patch.

I was guided by the rule from the Documentation/CodingGuidelines: When there are multiple arms to a conditional and some of them require braces, enclose even a single line block in braces for consistency.

I just saw it and wanted to change it. A commit message contains the reason why this is a good change to make. It lets others know what problems it's trying to solve or what usecase it tries to satisfy. The commit message basically needs to convince others why the change is necessary / desired, now, and in the future. This will help others to follow your thought process and it gives you the possiblity to communicate trade-offs you made, all which cannot inferred from the patch. For simple changes, the motivation can be simple too. To make it concrete: You are talking about a condition. What condition? And you say that the previously obtained value will not be necessary. What do you do with that value then? Why does this change improve the situation? These are things you can state in your commit message.

Is this intended as just a style change or a speculative performance change? So the general concept is: x = fa(); if (...) { if (...) { return 0; } x = fb(); } being rewritten as if (...) { if (...) { return 0; } x = fb(); } else { x = fa(); } or, in the last iteration if (!...) { x = fa(); } else { if (...) { return 0; } x = fb(); } which (at least conceptually) avoids setting x unnecessarily when we do the early return. I think the last iteration might suffer a bit from the condition inversion, since the comment feels a bit odd placed there at the "} else {" line, and if it were to be placed at the top, it would have to be negated "check if work tree is NOT already the prefix". Therefore I think the original or the first iteration might be a tad better from a readability perspective. (Going down this path, We could potentially also remove the 'off' variable completely, increment the 'path' pointer directly, and set the 'path0' pointer before, not sure if that's a good idea though...) -- Martin Erik Werner <martinerikwerner@gmail.com> ^ permalink raw reply [flat|nested] 7+ messages in thread

That is not quite correct. We do encourage if (...) single statement; with or without else another single statement; IOW, when both sides do not need curlies, we save vertical space. On the other hand, when one side needs curlies, we tend to add to both to make it easier to spot the correspondence, i.e. if (...) { compond statement; compond statement; } else { single statement; } or the other way around. if (...) { single statement; } else { compond statement; compond statement; } > However, we still encourage to put shorter alternative code paths > (i.e. the blocks after `if` and `else`) first, in your case: > > @@ -35,18 +35,19 @@ static int abspath_part_inside_repo(char *path) > return -1; > wtlen = strlen(work_tree); > len = strlen(path); > - off = offset_1st_component(path); > > /* check if work tree is already the prefix */ > - if (wtlen <= len && !strncmp(path, work_tree, wtlen)) { > + if (wtlen > len || strncmp(path, work_tree, wtlen)) > + off = offset_1st_component(path); > + else { > if (path[wtlen] == '/') { > memmove(path, path + wtlen + 1, len - wtlen); > return 0; > } else if (path[wtlen - 1] == '/' || path[wtlen] == '\0') { > /* work tree is the root, or the whole path */ > memmove(path, path + wtlen, len - wtlen + 1); > return 0; > } > /* work tree might match beginning of a symlink to work * tree */ > off = wtlen; > } This also may allow you to further dedent the if/else chain and make the result easier to follow.
