never write accum_buf on error in got_pack_dump_delta_chain_to_file()
and also avoid to override `err' if fwrite fails. ok millert, stsp
plug memory leak in got_pack_dump_delta_chain_to_file()
found by smatch. ok stsp@
change got_packidx_match_id_str_prefix not to reset the stailq
Since it appends to the given stailq, the ownership is moved and so don't initialize/reset it at the start and neither on error. The caller has to take care of the contents. (kind of) follow up to 2234939fb4. Based upon an original diff from jamsek; ok jamsek
do not forget to flush after writing a cached fulltext to a temporary file
Fixes the following error during gotadmin pack -a: gotadmin: raw object has unexpected size
remove dependency of gitwrapper, gotctl, and gotsh on object_parse.c
Move some functions from object_parse.c into hash.c. These functions either require hash.c code anyway or contain object ID implementation internals. Add a new file object_qid.c, for got_object_id_queue and got_object_qid. This new file must be linked to virtually every program.
add some helper functions to compute hashes
This adds a set of functions to abstract over SHA1Init, SHA1Update, SHA1Final, their respective SHA256 variants and how to compare digests. Replace all the SHA1*() usage with the new APIs. It's a preparatory step for sha256 handling. ok stsp@
rename lib/sha1.c to lib/hash.c
It will soon grow functions to deal with sha256 too. stsp@ agrees.
include sha2.h too where sha1.h is included
In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>
change add_delta to take an off_t instead of size_t.
add_delta already calls got_delta_open casting the size_t to off_t, and all the add_delta callers pass an off_t anyway; fixes an implicit off_t truncation. ok stsp@
check size before calling mmap(2)
It's only a preparatory step, as checking whether a size_t is less than SIZE_MAX is moot. In a follow-up commit, however, the `filesize' field of the struct got_pack will become off_t and these checks will kick in. This also makes consistent how we guard mmap(2) against empty files. ok and improvements stsp@
fix off_t type mismatch
off_t is a signed type and depending on the platform, it can be "long" or "long long", so cast to long long for printf().
change got_pack_parse_offset_delta tslen argument to size_t
The tslen argument is always in the (1..9) range so `int' is technically fine (even int8_t would be!) but all the callers are passing a size_t, so change the type accordingly. ok stsp@
close parent's end of imsg pipe before waiting for a child process to exit
Prevents a dead-lock in 'tog log' where tog wants to exit (e.g. because the user pressed Ctrl-C) while a got-read-pack child process wants to send more commits. Closing the parent's pipe descriptor makes writes to the pipe fail in the child process. The child then unwinds via an ERR_EOF error and exits, instead of forever polling its end of the pipe in order to write more data. ok jamsek
