2025-02-27Merge branch 'ua/os-version-capability'Junio C Hamano1-5/+64
The value of "uname -s" is by default sent over the wire as a part of the "version" capability. * ua/os-version-capability: agent: advertise OS name via agent capability t5701: add setup test to remove side-effect dependency version: extend get_uname_info() to hide system details version: refactor get_uname_info() version: refactor redact_non_printables() version: replace manual ASCII checks with isprint() for clarity
2025-02-19agent: advertise OS name via agent capabilityUsman Akinyemi1-1/+28
As some issues that can happen with a Git client can be operating system specific, it can be useful for a server to know which OS a client is using. In the same way it can be useful for a client to know which OS a server is using. Our current agent capability is in the form of "package/version" (e.g., "git/1.8.3.1"). Let's extend it to include the operating system name (os) i.e in the form "package/version-os" (e.g., "git/1.8.3.1-Linux"). Including OS details in the agent capability simplifies implementation, maintains backward compatibility, avoids introducing a new capability, encourages adoption across Git-compatible software, and enhances debugging by providing complete environment information without affecting functionality. The operating system name is retrieved using the 'sysname' field of the `uname(2)` system call or its equivalent. However, there are differences between `uname(1)` (command-line utility) and `uname(2)` (system call) outputs on Windows. These discrepancies complicate testing on Windows platforms. For example: - `uname(1)` output: MINGW64_NT-10.0-20348.3.4.10-87d57229.x86_64\ .2024-02-14.20:17.UTC.x86_64 - `uname(2)` output: Windows.10.0.20348 On Windows, uname(2) is not actually system-supplied but is instead already faked up by Git itself. We could have overcome the test issue on Windows by implementing a new `uname` subcommand in `test-tool` using uname(2), but except uname(2), which would be tested against itself, there would be nothing platform specific, so it's just simpler to disable the tests on Windows.

2025-02-18version: extend get_uname_info() to hide system detailsUsman Akinyemi1-7/+9
Currently, get_uname_info() function provides the full OS information. In a following commit, we will need it to provide only the OS name. Let's extend it to accept a "full" flag that makes it switch between providing full OS information and providing only the OS name. We may need to refactor this function in the future if an `osVersion.format` is added.

2025-02-18version: refactor get_uname_info()Usman Akinyemi1-0/+20
Some code from "builtin/bugreport.c" uses uname(2) to get system information. Let's refactor this code into a new get_uname_info() function, so that we can reuse it in a following commit.

2025-02-18version: refactor redact_non_printables()Usman Akinyemi1-6/+15
The git_user_agent_sanitized() function performs some sanitizing to avoid special characters being sent over the line and possibly messing up with the protocol or with the parsing on the other side. Let's extract this sanitizing into a new redact_non_printables() function, as we will want to reuse it in a following patch. For now the new redact_non_printables() function is still static as it's only needed locally. While at it, let's use strbuf_detach() to explicitly detach the string contained by the 'buf' strbuf.

2025-02-18version: replace manual ASCII checks with isprint() for clarityUsman Akinyemi1-1/+2
Since the isprint() function checks for printable characters, let's replace the existing hardcoded ASCII checks with it. However, since the original checks also handled spaces, we need to account for spaces explicitly in the new check.

2025-01-14meson: ensure correct version-def.h is usedToon Claes1-1/+6
To build the libgit-version library, Meson first generates `version-def.h` in the build directory. Then it compiles `version.c` into a library. During compilation, Meson tells to include both the build directory and the project root directory. However, when the user previously has compiled Git using Make, they will have a `version-def.h` file in project root directory as well. Because `version-def.h` is included in `version.c` using the #include directive with double quotes, some preprocessors will look for the header file in the same directory as the source file. This will cause compilation of `version.c` ran by Meson to include `version-def.h` previously made by Make, which might be out of date. To explicitly tell the preprocessor which `version-def.h` to use, pass the absolute path of this file as macro GIT_VERSION_H to the preprocessor using option `-D` and have `version.c` `#include GIT_VERSION_H`. To remain working with other build systems than Meson, include "version-def.h" if that macro is not defined.

2024-12-07Makefile: propagate Git version via generated headerPatrick Steinhardt1-0/+1
We set up a couple of preprocessor macros when compiling Git that propagate the version that Git was built from to `git version` et al. The way this is set up makes it harder than necessary to reuse the infrastructure across the different build systems. Refactor this such that we generate a "version-def.h" header via `GIT-VERSION-GEN` instead. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-12-06global: trivial conversions to fix `-Wsign-compare` warningsPatrick Steinhardt1-3/+1
We have a bunch of loops which iterate up to an unsigned boundary using a signed index, which generates warnigs because we compare a signed and unsigned value in the loop condition. Address these sites for trivial cases and enable `-Wsign-compare` warnings for these code units. This patch only adapts those code units where we can drop the `DISABLE_SIGN_COMPARE_WARNINGS` macro in the same step.

2017-12-14version --build-options: report commit, too, if possibleJohannes Schindelin1-0/+1
In particular when local tags are used (or tags that are pushed to some fork) to build Git, it is very hard to figure out from which particular revision a particular Git executable was built. It gets worse when those tags are deleted, or even updated. Let's just report an exact, unabbreviated commit name in our build options. We need to be careful, though, to report when the current commit cannot be determined, e.g. when building from a tarball without any associated Git repository. This could be the case also when extracting Git's source code into an unrelated Git worktree.

2012-08-03include agent identifier in capability stringJeff King1-0/+21
Instead of having the client advertise a particular version number in the git protocol, we have managed extensions and backwards compatibility by having clients and servers advertise capabilities that they support. This is far more robust than having each side consult a table of known versions, and provides sufficient information for the protocol interaction to complete. However, it does not allow servers to keep statistics on which client versions are being used. This information is not necessary to complete the network request (the capabilities provide enough information for that), but it may be helpful to conduct a general survey of client versions in use. We already send the client version in the user-agent header for http requests; adding it here allows us to gather similar statistics for non-http requests.

2012-06-03version: add git_user_agent functionJeff King1-0/+13
This is basically a fancy way of saying "git/$GIT_VERSION", except that it is overridable at build-time and through the environment. Which means that people who don't want to advertise their git version (for privacy or security reasons) can tweak it.
