git/http-backend.c, branch v2.3.3

Merge branch 'rs/run-command-env-array'

2014-10-24T21:57:54Z

Add managed "env" array to child_process to clarify the lifetime rules. * rs/run-command-env-array: use env_array member of struct child_process run-command: add env_array, an optional argv_array for env

use env_array member of struct child_process

2014-10-19T22:26:34Z

Convert users of struct child_process to using the managed env_array for specifying environment variables instead of supplying an array on the stack or bringing their own argv_array. This shortens and simplifies the code and ensures automatically that the allocated memory is freed after use. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

refs.c: change resolve_ref_unsafe reading argument to be a flags field

2014-10-15T17:47:24Z

resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency. Signed-off-by: Ronnie Sahlberg Signed-off-by: Jonathan Nieder Signed-off-by: Junio C Hamano

Merge branch 'rs/child-process-init'

2014-09-11T17:33:27Z

Code clean-up. * rs/child-process-init: run-command: inline prepare_run_command_v_opt() run-command: call run_command_v_opt_cd_env() instead of duplicating it run-command: introduce child_process_init() run-command: introduce CHILD_PROCESS_INIT

run-command: introduce CHILD_PROCESS_INIT

2014-08-20T16:53:37Z

Most struct child_process variables are cleared using memset first after declaration. Provide a macro, CHILD_PROCESS_INIT, that can be used to initialize them statically instead. That's shorter, doesn't require a function call and is slightly more readable (especially given that we already have STRBUF_INIT, ARGV_ARRAY_INIT etc.).

http-backend.c: replace `git_config()` with `git_config_get_bool()` family

2014-08-07T20:33:26Z

Use `git_config_get_bool()` family instead of `git_config()` to take advantage of the config-set API which provides a cleaner control flow. Signed-off-by: Tanay Abhra Reviewed-by: Matthieu Moy Signed-off-by: Junio C Hamano

* maint: use xmemdupz() to allocate copies of strings given by start and length use xcalloc() to allocate zero-initialized memory

use xmemdupz() to allocate copies of strings given by start and length

2014-07-21T17:37:02Z

Use xmemdupz() to allocate the memory, copy the data and make sure to NUL-terminate the result, all in one step. The resulting code is shorter, doesn't contain the constants 1 and '\0', and avoids duplicating function parameters. For blame, the last copied byte (o->file.ptr[o->file.size]) is always set to NUL by fake_working_tree_commit() or read_sha1_file(), so no information is lost by the conversion to using xmemdupz().

use skip_prefix to avoid magic numbers

2014-06-20T17:44:45Z

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: Jeff King Signed-off-by: Junio C Hamano
