# [RFC/PATCH] Add a new commit-raw command. 4 messages from 2009-02-24 to 2009-02-24. Participants: Felipe Contreras, Jeff King, Shawn O. Pearce. Thread: https://gitlist.dev/t/17996 ## Felipe Contreras, 2009-02-24 21:28 Subject: [RFC/PATCH] Add a new commit-raw command. Message-ID: <1235510914-23319-1-git-send-email-felipe.contreras@gmail.com> URL: https://gitlist.dev/e/1235510914-23319-1-git-send-email-felipe.contreras%40gmail.com ``` This command receives as input a raw commit object, and outputs the generated sha1. This is very useful when doing some serious repo reconstructions. For example: git cat-file -p 343ee25 | git write-raw 343ee2589d1b94772f513cc699765622351acb19 Signed-off-by: Felipe Contreras --- Makefile | 1 + builtin-commit-raw.c | 23 +++++++++++++++++++++++ builtin.h | 1 + git.c | 1 + 4 files changed, 26 insertions(+), 0 deletions(-) create mode 100644 builtin-commit-raw.c diff --git a/Makefile b/Makefile index b040a96..94212b3 100644 --- a/Makefile +++ b/Makefile @@ -524,6 +524,7 @@ BUILTIN_OBJS += builtin-checkout-index.o BUILTIN_OBJS += builtin-checkout.o BUILTIN_OBJS += builtin-clean.o BUILTIN_OBJS += builtin-clone.o +BUILTIN_OBJS += builtin-commit-raw.o BUILTIN_OBJS += builtin-commit-tree.o BUILTIN_OBJS += builtin-commit.o BUILTIN_OBJS += builtin-config.o diff --git a/builtin-commit-raw.c b/builtin-commit-raw.c new file mode 100644 index 0000000..66c41f4 --- /dev/null +++ b/builtin-commit-raw.c @@ -0,0 +1,23 @@ +/* + * Writes a raw commit object + */ + +#include "cache.h" +#include "commit.h" + +int cmd_commit_raw(int argc, const char **argv, const char *unused_prefix) +{ + unsigned char commit_sha1[20]; + struct strbuf buffer; + + strbuf_init(&buffer, 8192); + + strbuf_read(&buffer, 0, 0); + + if (!write_sha1_file(buffer.buf, buffer.len, "commit", commit_sha1)) { + printf("%s\n", sha1_to_hex(commit_sha1)); + return 0; + } + else + return 1; +} diff --git a/builtin.h b/builtin.h index 1495cf6..5c33e69 100644 --- a/builtin.h +++ b/builtin.h @@ -38,6 +38,7 @@ extern int cmd_cherry_pick(int argc, const char **argv, const char *prefix); extern int cmd_clone(int argc, const char **argv, const char *prefix); extern int cmd_clean(int argc, const char **argv, const char *prefix); extern int cmd_commit(int argc, const char **argv, const char *prefix); +extern int cmd_commit_raw(int argc, const char **argv, const char *prefix); extern int cmd_commit_tree(int argc, const char **argv, const char *prefix); extern int cmd_count_objects(int argc, const char **argv, const char *prefix); extern int cmd_describe(int argc, const char **argv, const char *prefix); diff --git a/git.c b/git.c index c2b181e..b033365 100644 --- a/git.c +++ b/git.c @@ -285,6 +285,7 @@ static void handle_internal_command(int argc, const char **argv) { "clone", cmd_clone }, { "clean", cmd_clean, RUN_SETUP | NEED_WORK_TREE }, { "commit", cmd_commit, RUN_SETUP | NEED_WORK_TREE }, + { "commit-raw", cmd_commit_raw, RUN_SETUP }, { "commit-tree", cmd_commit_tree, RUN_SETUP }, { "config", cmd_config }, { "count-objects", cmd_count_objects, RUN_SETUP }, -- 1.6.1.3 ``` ## Jeff King, 2009-02-24 22:14 Subject: Re: [RFC/PATCH] Add a new commit-raw command.
