or pushing to a Gerrit-monitored repository, your commit message must follow a specific structure to avoid being rejected. To "put together a solid text" that passes this check, follow these standard Git/Gerrit conventions: 1. The Subject Line (Max 65 Characters)

The first line must be a concise summary of the change. Gerrit often enforces a limit of 65 characters for this line. Stack Overflow Start with a prefix: Often a module name or "CC-65" if referencing a ticket. Use imperative mood: e.g., "Fix bug" instead of "Fixed bug." No period: Do not end the subject line with a period. 2. The Blank Line Always leave the second line completely

. This separates the summary from the detailed description, ensuring tools like git log --oneline work correctly. 3. The Body (Detailed Description)

This is where you explain the "why" and "how" of your changes. Wrap lines: Manually wrap your text at 72 characters to ensure it remains readable in all terminal viewers. cctools 65 new

Focus on the reasoning behind the change and any side effects, rather than just what code was moved. 4. Metadata (Footer) Include any required tags at the very bottom, such as:

2.4. Dynamic Library Compatibility Changes

install_name_tool received new options:

-delete_rpath – remove an existing rpath entry.
-add_rpath behavior improved to avoid duplicate entries.

otool -L now prints the current version and compatibility version of dynamic libraries by default. or pushing to a Gerrit-monitored repository, your commit

2. Stricter Symbol Hiding

The linker now respects .exports files more strictly. If your code relied on accidental exports, you must explicitly mark them.

Solution: Compile with -Wl,-warn_private_extern to identify missing exports.

5. Example Usage (v65 Specific)

1. Overview & Context

cctools (C Compiler Tools) is Apple’s open-source collection of low-level binary manipulation tools for Mach-O (Mach Object) files — the executable and object file format used by macOS, iOS, watchOS, tvOS, and bridgeOS. The suite includes classic UNIX-like tools such as:

otool (object file display)
lipo (fat binary creator/editor)
install_name_tool (dynamic library ID and rpath manipulation)
codesign_allocate (code signing helper)
segedit (segment editor)
nm, ar, ranlib, strip, size, strings, file (Mach-O versions)

Version 65 represents a specific milestone in the cctools lineage, tracked inside Apple’s Darwin open-source releases. It corresponds roughly to the Xcode 9.x / early Xcode 10 era (2017–2018), but the version number is independent of Xcode’s own versioning.

Note: cctools version numbers are not chronological with release dates; they increment with each Apple internal commit tagged for open-source export.
