![]() I've looked through Jenkins documentation, but could not locate anything that describes the mangling that occurs. I'd like to have a way that I could provide information that I have and yield the branch name as it exists on disk. While I have the branch name (in git), and the build-number, and can see the 'archive' subdirectory on disk, that directory often exists beneath a 'mangled' directory making it difficult to locate in a deterministic way. When Jenkins decides to eliminate an archive, I'd like to be able to react to that and initiate integration activity. Name Mangler 2.4.5 released We’ve just released a minor update to Name Mangler that includes only a couple of changes: A new optional parameter (sequence identifier) has been added to Advanced mode’s Sequential Numbering function. Length for MD5 output : Fixed-length always 128 bits For easier display, they are usually displayed in hex, which because each hex digit (0-1-2-3-4-5-6-7-8-9-A-B-C-D-E-F) takes up 4 bits of space, so its output can be displayed as 32 hex digits. In addition to the above, here are some other features of note: Save any renaming action as a Preset, and automatically sync those presets across Macs Export renaming actions for sharing via email, etc. Can anyone point me at (or describe) the logic that Jenkins is using?įor integration purposes, I am composing some scripts that want to inspect the jenkins disk to determine the presence (or absence) of archives under a build. Im trying to calculate an MD5 hash based on the file contents, not the file name. Name Mangler 3 represents a quantum leap forward in file renaming: speed and beauty combined with ease of use, and loaded with features. I've tried various hashing patterns (MD5, SHA1, etc), but none of them seem to produce the given hash. For longer branch names, it looks like it is also forcing a fixed length, by dropping characters from the middle - first 12 characters + hash (8 chars) + last 12 characters. I'm trying to figure out what Jenkins will call my branch.įor example: (branch name left, mangled name right) "develop" - "develop" "release-3.9" - "release-3-9.t0j1ui" "patch-3.14-cumulative" - "patch-3-14-cumulative.4l8tb2" "patch-3.5-state_of_michigan" - "patch-3-5-st.cp75rj.-of-michigan"Įmpirically, it replaces "." with "-" and is adding a hash. However, many branch names get altered presumably to remove illegal characters and keep the branch name short. Name Mangler provides a nice preview of the entire sequence. The final action in the series appends the date the episode was created. Create an MD5 collision by running the following command (but replace the vector on the command line with the one you found in step 4). In this case, match 1 is the episode ID and match 3 is the name of the episode if it exists. Run the following command to create an initialization vector. MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4. That’s right, Name Mangler returns the matching tokens and makes them accessible for creating file names. ![]() I have found that certain (short, simple) branches do not get mangled - e.g. The 128-bit (16-byte) MD5 hashes (also termed message digests) are typically represented as a sequence of 32 hexadecimal digits. Jenkins stores certain data about multi-branch jobs in "$JENKINS_HOME/jobs/PIPELINE_NAME/branches/MANGLED_BRANCHNAME". ![]()
