"git --no-lazy-fetch cmd" allows to run "cmd" while disabling lazy fetching of objects from the promisor remote, which may be handy for debugging. * jc/no-lazy-fetch: git: extend --no-lazy-fetch to work across subprocesses git: document GIT_NO_REPLACE_OBJECTS environment variable git: --no-lazy-fetch option

trace2: emit 'def_param' set with 'cmd_name' event

2024-03-07T18:24:34Z

Some commands do not cause a set of 'def_param' events to be emitted. This includes "git-remote-https", "git-http-fetch", and various "query" commands, like "git --man-path". Since all of these commands do emit a 'cmd_name' event, add code to the "trace2_cmd_name()" function to generate the set of 'def_param' events. Remove explicit calls to "trace2_cmd_list_config()" and "trace2_cmd_list_env_vars()" in git.c since they are no longer needed.

git: extend --no-lazy-fetch to work across subprocesses

2024-02-27T17:53:14Z

Modeling after how the `--no-replace-objects` option is made usable across subprocess spawning (e.g., cURL based remote helpers are spawned as a separate process while running "git fetch"), allow the `--no-lazy-fetch` option to be passed across process boundaries. Do not model how the value of GIT_NO_REPLACE_OBJECTS environment variable is ignored, though. Just use the usual git_env_bool() to allow "export GIT_NO_LAZY_FETCH=0" and "unset GIT_NO_LAZY_FETCH" to be equivalents. Also do not model how the request is not propagated to subprocesses we spawn (e.g. "git clone --local" that spawns a new process to work in the origin repository, while the original one working in the newly created one) by the "--no-replace-objects" option, as this "do not lazily fetch from the promisor" is more about a per-request debugging aid, not "this repository's promisor should not be relied upon" property specific to a repository.

git: --no-lazy-fetch option

2024-02-13T20:53:15Z

Sometimes, especially during tests of low level machinery, it is handy to have a way to disable lazy fetching of objects. This allows us to say, for example, "git cat-file -e ", to see if the object is locally available. Signed-off-by: Junio C Hamano

replay: introduce new builtin

2023-11-26T01:10:48Z

For now, this is just a rename from `t/helper/test-fast-rebase.c` into `builtin/replay.c` with minimal changes to make it build appropriately. Let's add a stub documentation and a stub test script though. Subsequent commits will flesh out the capabilities of the new command and make it a more standard regular builtin.

read-cache*.h: move declarations for read-cache.c functions from cache.h

2023-06-21T20:39:53Z

For the functions defined in read-cache.c, move their declarations from cache.h to a new header, read-cache-ll.h. Also move some related inline functions from cache.h to read-cache.h. The purpose of the read-cache-ll.h/read-cache.h split is that about 70% of the sites don't need the inline functions and the extra headers they include.

repository: create disable_replace_refs()

2023-06-12T20:34:55Z

Several builtins depend on being able to disable the replace references so we actually operate on each object individually. These currently do so by directly mutating the 'read_replace_refs' global. A future change will move this global into a different place, so it will be necessary to change all of these lines. However, we can simplify that transition by abstracting the purpose of these global assignments with a method call. We will need to keep this read_replace_refs global forever, as we want to make sure that we never use replace refs throughout the life of the process if this method is called. Future changes may present a repository-scoped version of the variable to represent that repository's core.useReplaceRefs config value, but a zero-valued read_replace_refs will always override such a setting.
