Goals, Benefits & What Changes for Users + +### What Changed for Users + +**Nothing.** GAM behaves identically. Every command, flag, and output format is unchanged. Performance is the same or slightly better. This was a purely internal restructuring. + +### Why We Did This + +`gam/__init__.py` was a **72,735-line monolith** — a single file containing virtually all of GAM's logic. Every Google Workspace API surface (Drive, Gmail, Calendar, Classroom, Groups, Vault, Chat, ChromeOS, etc.) lived in one file. This created real problems: + +- **Navigating the codebase was painful.** Finding where a command was implemented meant scrolling through 73K lines or relying on grep. No IDE could provide useful file-level structure because everything was in one file. +- **Merge conflicts were constant.** Any two developers touching different features (say, Drive and Gmail) would conflict because they were editing the same file. +- **Understanding scope was impossible.** Which constants belong to Drive? Which helper functions are shared vs. specific to Gmail? When everything is in one namespace, you can't tell. +- **Code review was difficult.** A PR that modifies "Drive label permissions" shouldn't require a reviewer to open a 73K-line file and locate the relevant section. + +### What the New Layout Achieves + +| Before | After | +|--------|-------| +| 1 file, 72,735 lines | 95 files, all under 100KB | +| `gam/__init__.py` does everything | `gam/__init__.py` is a thin hub (~4,660 lines) | +| Find a function: scroll or grep the monolith | Find a function: look in the obvious module | +| Merge conflicts on every PR | Parallel work on Drive, Gmail, etc. with no conflicts | + +**Concrete benefits for developers:** + +1. **Find things fast.** Working on Gmail labels? Open `gam/cmd/gmail/labels.py`. Working on shared drive permissions? Open `gam/cmd/drive/shareddrives.py`. The file name tells you what's inside. + +2. **Smaller blast radius.** A change to Drive copy/move logic only touches `gam/cmd/drive/copymove/`. Reviewers can focus on the relevant 50-90KB file instead of a 73K-line monolith. + +3. **Better IDE support.** File outlines, go-to-definition, and symbol search all work better with reasonably-sized files. Your IDE's file explorer now shows a meaningful tree. + +4. **Easier onboarding.** A new contributor can understand the codebase structure by looking at the directory tree. "Oh, Chat commands are in `cmd/chat/`, Drive stuff is in `cmd/drive/`" — it's self-documenting. + +5. **No performance cost.** `gam print users` runs in ~0.39s, identical to before. Python's import system caches modules, so the split adds negligible startup overhead. + +--- + +## 2.

If you're looking for Gmail label code, check `gam/cmd/gmail/labels.py`. If you want Drive shared drive logic, check `gam/cmd/drive/shareddrives.py`. + +**Method 2: grep.** +```bash +# Find where a function is defined +grep -rn "def copyDriveFile" src/gam/cmd/ + +# Result: src/gam/cmd/drive/copymove/copymove_util.py:947 +``` + +**Method 3: Check the dispatch table.** If you know the GAM command name, search the dispatch tables in `__init__.py`: +```bash +grep "copyDriveFile\|copy.*drivefile" src/gam/__init__.py + +# Shows: Cmd.ARG_DRIVEFILE: copyDriveFile, +# Then grep for the import to find its module: +# from gam.cmd.drive import ( ... copyDriveFile, ... ) +``` + +**Method 4: Follow the re-export chain.** Every function is re-exported from `__init__.py`. Search for the name there to see which `cmd/` module it comes from: +```bash +grep -B50 "copyDriveFile," src/gam/__init__.py | grep "^from" + +# Result: from gam.cmd.drive import ( +# Then check drive/__init__.py to find the sub-module: +grep -B20 "copyDriveFile," src/gam/cmd/drive/__init__.py | grep "^from" + +# Result: from gam.cmd.drive.copymove import ( +# And finally: +grep -B20 "copyDriveFile," src/gam/cmd/drive/copymove/__init__.py | grep "^from" + +# Result: from gam.cmd.drive.copymove.copymove_util import ( +``` + +**Method 5: Your IDE.** Open `__init__.py`, Ctrl/Cmd-click on any function name, and your IDE will jump to the definition in the correct `cmd/` sub-module. + +### The Module Pattern + +Every extracted module follows the same pattern: + +```python +"""Brief description of what this module handles.""" + +import sys +from gamlib import glaction +from gamlib import glapi as API +from gamlib import glcfg as GC +from gamlib import glclargs +from gamlib import glentity +from gamlib import glindent +# ... other imports as needed + +Act = glaction.GamAction() +Ent = glentity.GamEntity() +Ind = glindent.GamIndent() +Cmd = glclargs.GamCLArgs() + +def _getMain(): + return sys.modules['gam'] +``` + +Key points: + +- **`_getMain()`** provides lazy runtime access to the `gam` module (i.e., `__init__.py`). This avoids circular imports — modules can't directly `import gam` during initialization because `gam` is still loading. Instead, they call `_getMain()` at runtime when the function is actually executed. Any function defined in `__init__.py` or re-exported through it is accessible as `_getMain().functionName()`. +- **`Act`, `Ent`, `Ind`, `Cmd`** are local instances of the standard GAM helper classes. These four classes (`GamAction`, `GamEntity`, `GamIndent`, `GamCLArgs`) use **class-level shared state**, meaning all instances across all modules see the same values. When `__init__.py` calls `Act.Set(Act.CREATE)` before dispatching to a command handler, every module's `Act` instance immediately reflects that action. This was necessary because the original monolith had a single instance of each; the refactoring created multiple instances that must stay synchronized. +- **Module-level constants** that were originally in `__init__.py` (like `MIMETYPE_GA_FOLDER`, `ME_IN_OWNERS`, `UNKNOWN`, `UTF8`, etc.) are duplicated into the modules that need them. This avoids import-time dependencies on the not-yet-loaded hub. +- **Cross-module function calls** use `_getMain()` for GAM-internal functions (e.g., `_getMain().entityUnknownWarning(...)`) rather than direct imports, which would cause circular import errors during module loading. Standard library and third-party imports (e.g., `from passlib.hash import sha512_crypt`) are safe to import directly at module level. + +--- + +## 3. What Happened to GData (Audit and Domain Shared Contacts)? + +GAM previously used two legacy Google APIs built on the GData XML protocol: + +1. **Email Audit API** — `gam audit monitor create/delete/list` +2. **Domain Shared Contacts API** — `gam create/update/delete/print contacts` + +Both APIs, along with the vendored `gdata/` and `atom/` libraries (~10,000 lines), have been **completely removed**. + +The affected commands now print a deprecation notice: + +``` +ERROR: GAM no longer supports the legacy API and this command. +If you must use this API you can install a copy of GAM 7.46.07 +which is the last version to support this command. +``` + +`contacts.py` still contains the People API utilities (shared constants, `PeopleManager`, etc.) used by `people.py` for modern user contact management. diff --git a/src/gam/util/api.py b/src/gam/util/api.py index 296b6f66..11d4420f 100644 --- a/src/gam/util/api.py +++ b/src/gam/util/api.py @@ -1,7 +1,7 @@ """GAM API utility functions.
