2021-08-27show-branch: simplify rev_is_head()René Scharfe

2021-06-28show-branch: don't <COLOR></RESET> for space charactersÆvar Arnfjörð Bjarmason
Change the colored output introduced in ab07ba2a24 (show-branch: color the commit status signs, 2009-04-22) to not color and reset each individual space character we use for padding. The intent is to color just the "!", "+" etc. characters. This makes the output easier to test, so let's do that now. The test would be much more verbose without a color/reset for each space character. Since the coloring cycles through colors we previously had a "rainbow of space characters". In theory this breaks things for anyone who's relying on the exact colored output of show-branch, in practice I'd think anyone parsing it isn't actively turning on the colored output.

2020-09-09Merge branch 'jt/interpret-branch-name-fallback'Junio C Hamano
"git status" has trouble showing where it came from by interpreting reflog entries that recordcertain events, e.g. "checkout @{u}", and gives a hard/fatal error. Even though it inherently is impossible to give a correct answer because the reflog entries lose some information (e.g. "@{u}" does not record what branch the user was on hence which branch 'the upstream' needs to be computed, and even if the record were available, the relationship between branches may have changed), at least hide the error to allow "status" show its output. * jt/interpret-branch-name-fallback: wt-status: tolerate dangling marks refs: move dwim_ref() to header file sha1-name: replace unsigned int with option struct
2020-09-02wt-status: tolerate dangling marksJonathan Tan
When a user checks out the upstream branch of HEAD, the upstream branch not being a local branch, and then runs "git status", like this: git clone $URL client cd client git checkout @{u} git status no status is printed, but instead an error message: fatal: HEAD does not point to a branch (This error message when running "git branch" persists even after checking out other things - it only stops after checking out a branch.) This is because "git status" reads the reflog when determining the "HEAD detached" message, and thus attempts to DWIM "@{u}", but that doesn't work because HEAD no longer points to a branch. Therefore, when calculating the status of a worktree, tolerate dangling marks. This is done by adding an additional parameter to dwim_ref() and repo_dwim_ref().

2020-07-31strvec: rename struct fieldsJeff King
The "argc" and "argv" names made sense when the struct was argv_array, but now they're just confusing. Let's rename them to "nr" (which we use for counts elsewhere) and "v" (which is rather terse, but reads well when combined with typical variable names like "args.v"). Note that we have to update all of the callers immediately. Playing tricks with the preprocessor is hard here, because we wouldn't want to rewrite unrelated tokens.

2020-07-28strvec: convert builtin/ callers away from argv_array nameJeff King
We eventually want to drop the argv_array name and just use strvec consistently. There's no particular reason we have to do it all at once, or care about interactions between converted and unconverted bits. Because of our preprocessor compat layer, the names are interchangeable to the compiler (so even a definition and declaration using different names is OK). This patch converts all of the files in builtin/ to keep the diff to a manageable size. The conversion was done purely mechanically with: git ls-files '*.c' '*.h' | xargs perl -i -pe ' s/ARGV_ARRAY/STRVEC/g; s/argv_array/strvec/g; ' and then selectively staging files with "git add builtin/". We'll deal with any indentation/style fallouts separately. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FDenton Liu
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code. Finally, using `git grep OPTION_CALLBACK \*.c`, leftover results which were not handled by the script were manually transformed.

2018-11-06assert NOARG/NONEG behavior of parse-options callbacksJeff King
When we define a parse-options callback, the flags we put in the option struct must match what the callback expects. For example, a callback which does not handle the "unset" parameter should only be used with PARSE_OPT_NONEG. But since the callback and the option struct are not defined next to each other, it's easy to get this wrong (as earlier patches in this series show). Fortunately, the compiler can help us here: compiling with -Wunused-parameters can show us which callbacks ignore their "unset" parameters (and likewise, ones that ignore "arg" expect to be triggered with PARSE_OPT_NOARG). But after we've inspected a callback and determined that all of its callers use the right flags, what do we do next? We'd like to silence the compiler warning, but do so in a way that will catch any wrong calls in the future. We can do that by actually checking those variables and asserting that they match our expectations. Because this is such a common pattern, we'll introduce some helper macros. The resulting messages aren't as descriptive as we could make them, but the file/line information from BUG() is enough to identify the problem (and anyway, the point is that these should never be seen). Each of the annotated callbacks in this patch triggers -Wunused-parameters, and was manually inspected to make sure all callers use the correct options (so none of these BUGs should be triggerable).

2018-11-06show-branch: mark --reflog option as NONEGJeff King
Running "git show-branch --no-reflog" will behave as if "--reflog" was given with no options, which makes no sense.

2018-08-29convert "oidcmp() != 0" to "!oideq()"Jeff King
This is the flip side of the previous two patches: checking for a non-zero oidcmp() can be more strictly expressed as inequality. Like those patches, we write "!= 0" in the coccinelle transformation, which covers by isomorphism the more common: if (oidcmp(E1, E2)) As with the previous two patches, this patch can be achieved almost entirely by running "make coccicheck"; the only differences are manual line-wrap fixes to match the original code. There is one thing to note for anybody replicating this, though: coccinelle 1.0.4 seems to miss the case in builtin/tag.c, even though it's basically the same as all the others. Running with 1.0.7 does catch this, so presumably it's just a coccinelle bug that was fixed in the interim. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-03parse-options: automatically infer PARSE_OPT_LITERAL_ARGHELPRené Scharfe
Parseopt wraps argument help strings in a pair of angular brackets by default, to tell users that they need to replace it with an actual value. This is useful in most cases, because most option arguments are indeed single values of a certain type. The option PARSE_OPT_LITERAL_ARGHELP needs to be used in option definitions with arguments that have multiple parts or are literal strings. Stop adding these angular brackets if special characters are present, as they indicate that we don't deal with a simple placeholder. This simplifies the code a bit and makes defining special options slightly easier. Remove the flag PARSE_OPT_LITERAL_ARGHELP in the cases where the new and more cautious handling suffices.

This reverts commit 136c8c8b8fa39f1315713248473dececf20f8fe7. That commit was trying to address a bug caused by 4c7f1819b3 (make color.ui default to 'auto', 2013-06-10), in which plumbing like diff-tree defaulted to "auto" color, but did not respect a "color.ui" directive to disable it. But it also meant that we started respecting "color.ui" set to "always". This was a known problem, but 4c7f1819b3 argued that nobody ought to be doing that. However, that turned out to be wrong, and we got a number of bug reports related to "add -p" regressing in v2.14.2. Let's revert 136c8c8b8, fixing the regression to "add -p". This leaves the problem from 4c7f1819b3 unfixed, but: 1. It's a pretty obscure problem in the first place. I only noticed it while working on the color code, and we haven't got a single bug report or complaint about it. 2. We can make a more moderate fix on top by respecting "never" but not "always" for plumbing commands. This is just the minimal fix to go back to the working state we had before v2.14.2. Note that this isn't a pure revert. We now have a test in t3701 which shows off the "add -p" regression. This can be flipped to success.

2017-07-13color: check color.ui in git_default_config()Jeff King
Back in prehistoric times, our decision on whether or not to show color by default relied on using a config callback that either did or didn't load color config like color.diff. When we introduced color.ui, we put it in the same boat: commands had to manually respect it by using git_color_config() or its git_color_default_config() convenience wrapper. But in 4c7f1819b (make color.ui default to 'auto', 2013-06-10), that changed. Since then, we default color.ui to auto in all programs, meaning that even plumbing commands like "git diff-tree --pretty" might colorize the output. Nobody seems to have complained in the intervening years, presumably because the "is stdout a tty" check does a good job of catching the right cases. But that leaves an interesting curiosity: color.ui defaults to auto even in plumbing, but you can't actually _disable_ the color via config. So if you really hate color and set "color.ui" to false, diff-tree will still show color (but porcelain like git-diff won't). Nobody noticed that either, probably because very few people disable color. One could argue that the plumbing should _always_ disable color unless an explicit --color option is given on the command line. But in practice, this creates a lot of complications for scripts which do want plumbing to show user-visible output. They can't just pass "--color" blindly; they need to check the user's config and decide what to send. Given that nobody has complained about the current behavior, let's assume it's a good path, and follow it to its conclusion: supporting color.ui everywhere. Note that you can create havoc by setting color.ui=always in your config, but that's more or less already the case. We could disallow it entirely, but it is handy for one-offs like: git -c color.ui=always foo >not-a-tty when "foo" does not take a --color option itself.

2017-05-08Convert lookup_commit* to struct object_idbrian m. carlson
Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

2017-04-27timestamp_t: a new data type for timestampsJohannes Schindelin
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

2017-02-27Merge branch 'jk/show-branch-lift-name-len-limit'Junio C Hamano
"git show-branch" expected there were only very short branch names in the repository and used a fixed-length buffer to hold them without checking for overflow. * jk/show-branch-lift-name-len-limit: show-branch: use skip_prefix to drop magic numbers show-branch: store resolved head in heap buffer show-branch: drop head_len variable
2017-02-15show-branch: use skip_prefix to drop magic numbersJeff King
We make several starts_with() calls, only to advance pointers. This is exactly what skip_prefix() is for, which lets us avoid manually-counted magic numbers. Helped-by: Pranit Bauva <pranit.bauva@gmail.com> Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-14show-branch: store resolved head in heap bufferJeff King
We resolve HEAD and copy the result to a fixed-size buffer with memcpy, never checking that it actually fits. This bug dates back to 8098a178b (Add git-symbolic-ref, 2005-09-30). Before that we used readlink(), which took a maximum buffer size. We can fix this by using resolve_refdup(), which duplicates the buffer on the heap. That also lets us just check for a NULL pointer to see if we have resolved HEAD, and drop the extra head_p variable.

2017-02-14show-branch: drop head_len variableJeff King
We copy the result of resolving HEAD into a buffer and keep track of its length. But we never actually use the length for anything besides the copy. Let's stop passing it around. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-11-20Remove get_object_hash.brian m. carlson
Convert all instances of get_object_hash to use an appropriate reference to the hash member of the oid member of struct object. This provides no functional change, as it is essentially a macro substitution. Signed-off-by: brian m. carlson <sandals@crustytoothpaste.net> Signed-off-by: Jeff King <peff@peff.net>
