It is stored in Git’s object database directly. The tree object for the directory where the submodule lives will have an entry for the submodule’s commit (this is the so-called “gitlink”). Try doing git ls-tree master <path-to-directory-containing-submodule> (or just git ls-tree master if the submodule lives in the top-level directory).
Intel has upcoming instructions for accelerating the calculation of SHA1 /256 hashes. You can read more about them, how to detect if your CPU support them and how to use them here. (But not SHA-512, you’ll still need to manually vectorize that with regular SIMD instructions. AVX512 should help for SHA-512 (and for SHA-1 / … Read more
In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don’t need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus … Read more
Why does it not use a more modern version of SHA? Dec. 2017: It will. And Git 2.16 (Q1 2018) is the first release to illustrate and implement that intent. Note: see Git 2.19 below: it will be SHA-256. Git 2.16 will propose an infrastructure to define what hash function is used in Git, and … Read more
I ran into the same issue trying to use DigestUtils in my Android app. This was the best answer I could find by searching, but I was reluctant to rebuild the .jar file with the namespace changed. After spending some time on this issue, I found an easier way to solve the problem for my … Read more
This question is actually answered in Chapter 7 of the Pro Git book: Generally, eight to ten characters are more than enough to be unique within a project. One of the largest Git projects, the Linux kernel, is beginning to need 12 characters out of the possible 40 to stay unique. 7 digits are the … Read more
The usual answer goes thus: what is the probability that a rogue asteroid crashes on Earth within the next second, obliterating civilization-as-we-know-it, and killing off a few billion people? It can be argued that any unlucky event with a probability lower than that is not actually very important. If we have a “perfect” hash function … Read more
I solve this by SQL command: ALTER USER ‘mysqlUsername’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘mysqlUsernamePassword’; which is referenced by https://dev.mysql.com/doc/refman/8.0/en/alter-user.html if you are creating new user CREATE USER ‘jeffrey’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’; which is referenced by https://dev.mysql.com/doc/refman/8.0/en/create-user.html this works for me
