We get loose object names like "objects/??/..." from the remote side, and need to convert them to their hex representation. The code to do so is rather hard to follow, as it uses some calculated lengths whose origins are hard to understand and verify (e.g., the path must be exactly 49 characters long. why? Why doesn't the strcpy overflow obj_hex, which is the same length as path?). We can simplify this a bit by using skip_prefix, using standard 40- and 20-character buffers for hex and binary sha1s, and adding some comments. We also drop a totally bogus comment that claims strlcpy cannot be used because "path" is not NUL-terminated. Right between a call to strlen(path) and strcpy(path).

In some cases, we use starts_with to check for a prefix, and then use an already-calculated prefix length to advance a pointer past the prefix. There are no magic numbers or duplicated strings here, but we can still make the code simpler and more obvious by using skip_prefix.

After handling options, any leftover arguments should be commands. However, we pass through "--help" and "--version", so that we convert them into "git help" and "git version" respectively. This is a straightforward use of skip_prefix to avoid a magic number, but while we are there, it is worth adding a comment to explain this otherwise confusing behavior.

There are several uses of the magic number "line+45" when parsing ACK lines from the server, and it's rather unclear why 45 is the correct number. We can make this more clear by keeping a running pointer as we parse, using skip_prefix to jump past the first "ACK ", then adding 40 to jump past get_sha1_hex (which is still magical, but hopefully 40 is less magical to readers of git code). Note that this actually puts us at line+44. The original required some character between the sha1 and further ACK flags (it is supposed to be a space, but we never enforced that). We start our search for flags at line+44, which meanas we are slightly more liberal than the old code. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When we see a file change in a commit, we expect one of: 1. A mark. 2. An "inline" keyword. 3. An object sha1. The handling of spaces is inconsistent between the three options. Option 1 calls a sub-function which checks for the space, but doesn't parse past it. Option 2 parses the space, then deliberately avoids moving the pointer past it. Option 3 detects the space locally but doesn't move past it. This is confusing, because it looks like option 1 forgets to check for the space (it's just buried). And option 2 checks for "inline ", but only moves strlen("inline") characters forward, which looks like a bug but isn't. We can make this more clear by just having each branch move past the space as it is checked (and we can replace the doubled use of "inline" with a call to skip_prefix).

As in earlier commits, the diff option parser uses starts_with to find that an argument starts with "--stat-", and then adds strlen("stat-") to find the rest of the option. However, in this case the starts_with and the strlen are separated across functions, making it easy to call the latter without the former. Let's use skip_prefix instead of raw pointer arithmetic to catch such a case. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Like earlier cases, we can use skip_prefix to avoid magic numbers that must match the length of starts_with prefixes. However, the numbers are a little more complicated here, as we keep parsing past the prefix. We can solve it by keeping a running pointer as we parse; its final value is the location we want.

Fast-import does a lot of parsing of commands and dispatching to sub-functions. For example, given "option foo", we might recognize "option " using starts_with, and then hand it off to parse_option() to do the rest. However, we do not let parse_option know that we have parsed the first part already. It gets the full buffer, and has to skip past the uninteresting bits. Some functions simply add a magic constant: char *option = command_buf.buf + 7; Others use strlen: char *option = command_buf.buf + strlen("option "); And others use strchr: char *option = strchr(command_buf.buf, ' ') + 1; All of these are brittle and easy to get wrong (especially given that the starts_with call and the code that assumes the presence of the prefix are far apart). Instead, we can use skip_prefix, and just pass each handler a pointer to its arguments. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

It's a common idiom to match a prefix and then skip past it with strlen, like: if (starts_with(foo, "bar")) foo += strlen("bar"); This avoids magic numbers, but means we have to repeat the string (and there is no compiler check that we didn't make a typo in one of the strings). We can use skip_prefix to handle this case without repeating ourselves. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

It's a common idiom to match a prefix and then skip past it with a magic number, like: if (starts_with(foo, "bar")) foo += 3; This is easy to get wrong, since you have to count the prefix string yourself, and there's no compiler check if the string changes. We can use skip_prefix to avoid the magic numbers here. Note that some of these conversions could be much shorter. For example: if (starts_with(arg, "--foo=")) { bar = arg + 6; continue; } could become: if (skip_prefix(arg, "--foo=", &bar)) continue; However, I have left it as: if (skip_prefix(arg, "--foo=", &v)) { bar = v; continue; } to visually match nearby cases which need to actually process the string. Like: if (skip_prefix(arg, "--foo=", &v)) { bar = atoi(v); continue; } Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

We detect the "import-marks" capability by looking for that string, but _without_ a trailing space. Then we skip past it using strlen("import-marks "), with a space. So if a remote helper gives us exactly "import-marks", we will read past the end-of-string by one character. This is unlikely to be a problem in practice, because such input is malformed in the first place, and because there is a good chance that the string has an extra NUL terminator one character after the original (because it formerly had a newline in it that we parsed off). We can fix it by using skip_prefix with "import-marks ", with the space. The other form appears to be a typo from a515ebe9 (transport-helper: implement marks location as capability, 2011-07-16); "import-marks" has never existed without an argument, and it should match the "export-marks" definition above. Speaking of which, we can also use skip_prefix in a few other places while we are in the function. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Fast-import shares code between its command-line parser and the "option" command. To do so, it strips the "--" from any command-line options and passes them to the option parser. However, it does not confirm that the option even begins with "--" before blindly passing "arg + 2". It does confirm that the option starts with "-", so the only affected case was: git fast-import - which would read uninitialized memory after the argument. We can fix it by using skip_prefix and checking the result. As a bonus, this gets rid of some magic numbers.

A submodule diff generally has content like: -Subproject commit [0-9a-f]{40} +Subproject commit [0-9a-f]{40} When we are using "git apply --index" with a submodule, we first apply the textual diff, and then parse that result to figure out the new sha1. If the diff has bogus input like: -Subproject commit 1234567890123456789012345678901234567890 +bogus we will parse the "bogus" portion. Our parser assumes that the buffer starts with "Subproject commit", and blindly skips past it using strlen(). This can cause us to read random memory after the buffer. This problem was unlikely to have come up in practice (since it requires a malformed diff), and even when it did, we likely noticed the problem anyway as the next operation was to call get_sha1_hex on the random memory. However, we can easily fix it by using skip_prefix to notice the parsing error. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched. This lets you write: if (skip_prefix(arg, "foo ", &arg)) do_foo(arg); else if (skip_prefix(arg, "bar ", &arg)) do_bar(arg); Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

There's no point in using: if (skip_prefix(buf, "foo")) over if (starts_with(buf, "foo")) as the point of skip_prefix is to return a pointer to the data after the prefix. Using starts_with is more readable, and will make refactoring skip_prefix easier. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

This function originally took a whole config variable name ("var") and an offset ("ofs"). It checked "var+ofs" against each color slot, but reported errors using the whole "var". However, since 8b8e8624 (ignore unknown color configuration, 2009-12-12), it returns -1 rather than printing its own error, and therefore only cares about var+ofs. We can drop the ofs parameter and teach its sole caller to derive the pointer itself. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
