[PATCH v3] git-p4: improve encoding handling to support inconsistent encodings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tao Klerks <tao@xxxxxxxxxx>

git-p4 is designed to run correctly under python2.7 and python3, but
its functional behavior wrt importing user-entered text differs across
these environments:

Under python2, git-p4 "naively" writes the Perforce bytestream into git
metadata (and does not set an "encoding" header on the commits); this
means that any non-utf-8 byte sequences end up creating invalidly-encoded
commit metadata in git.

Under python3, git-p4 attempts to decode the Perforce bytestream as utf-8
data, and fails badly (with an unhelpful error) when non-utf-8 data is
encountered.

Perforce clients (especially p4v) encourage user entry of changelist
descriptions (and user full names) in OS-local encoding, and store the
resulting bytestream to the server unmodified - such that different
clients can end up creating mutually-unintelligible messages. The most
common inconsistency, in many Perforce environments, is likely to be utf-8
(typical in linux) vs cp-1252 (typical in windows).

Make the changelist-description- and user-fullname-handling code
python-runtime-agnostic, introducing three "strategies" selectable via
config:
- 'passthrough', behaving as previously under python2,
- 'strict', behaving as previously under python3, and
- 'fallback', favoring utf-8 but supporting a secondary encoding when
utf-8 decoding fails, and finally escaping high-range bytes if the
decoding with the secondary encoding also fails.

Keep the python2 default behavior as-is ('legacy' strategy), but switch
the python3 default strategy to 'fallback' with default fallback encoding
'cp1252'.

Also include tests exercising these encoding strategies, documentation for
the new config, and improve the user-facing error messages when decoding
does fail.

    RFC: Git p4 encoding strategy
    
    OPEN QUESTIONS:
    
     * Does it make sense to make "fallback" the default decoding strategy
       in python3? This is definitely a change in behavior, but I believe
       for the better; failing with "we defaulted to strict, but you can run
       again with this other option if you want it to work" seems unkind,
       only making sense if we thought fallback to cp1252 would be wrong in
       a substantial proportion of cases...
     * Is it OK to duplicate the bulk of the testing code across
       t9835-git-p4-metadata-encoding-python2.sh and
       t9836-git-p4-metadata-encoding-python3.sh?
     * Is it OK to explicitly call "git-p4.py" in tests, rather than the
       build output "git-p4", in order to be able to select the python
       runtime on a per-test basis? Is there a better approach?
     * Is the naming of the strategies appropriate? Should the default
       python2 strategy be called something less opinionated, like
       "passthrough"?
    
    Changes wrt v1:
    
     * Added "and replace any remaining unmappable bytes" behavior to the
       "fallback" strategy; common reasonable encodings like cp1252 still
       contain unmapped codepoints, and if those are found, there is really
       nothing that can be done about it other than ignoring the crazy
       bytes; this approach is consistent with the longstanding
       path-encoding-handling strategy.
     * Simplified error-handling accordingly
     * Cleaned up tests & commit messages slightly

@@ -636,7 +636,42 @@ git-p4.pathEncoding::
 	Git expects paths encoded as UTF-8. Use this config to tell git-p4
 	what encoding Perforce had used for the paths. This encoding is used
 	to transcode the paths to UTF-8. As an example, Perforce on Windows
-	often uses "cp1252" to encode path names.
+	often uses "cp1252" to encode path names. If this option is passed
+	into a p4 clone request, it is persisted in the resulting new git
+	repo.
+
+git-p4.metadataDecodingStrategy::
+	Perforce keeps the encoding of a changelist descriptions and user
+	full names as stored by the client on a given OS. The p4v client
+	uses the OS-local encoding, and so different users can end up storing
+	different changelist descriptions or user full names in different
+	encodings, in the same depot.
+	Git tolerates inconsistent/incorrect encodings in commit messages
+	and author names, but expects them to be specified in utf-8.
+	git-p4 can use three different decoding strategies in handling the
+	encoding uncertainty in Perforce: 'passthrough' simply passes the
+	original bytes through from Perforce to git, creating usable but
+	incorrectly-encoded data when the Perforce data is encoded as
+	anything other than utf-8. 'strict' expects the Perforce data to be
+	encoded as utf-8, and fails to import when this is not true.
+	'fallback' attempts to interpret the data as utf-8, and otherwise
+	falls back to using a secondary encoding - by default the common
+	windows encoding 'cp-1252' - with upper-range bytes escaped if
+	decoding with the fallback encoding also fails.
+	Under python2 the default strategy is 'passthrough' for historical
+	reasons, and under python3 the default is 'fallback'.
+	When 'strict' is selected and decoding fails, the error message will
+	propose changing this config parameter as a workaround. If this
+	option is passed into a p4 clone request, it is persisted into the
+	resulting new git repo.
+
+git-p4.metadataFallbackEncoding::
+	Specify the fallback encoding to use when decoding Perforce author
+	names and changelists descriptions using the 'fallback' strategy
+	(see git-p4.metadataDecodingStrategy). The fallback encoding will
+	only be used when decoding as utf-8 fails. This option defaults to
+	cp1252, a common windows encoding. If this option is passed into a
+	p4 clone request, it is persisted into the resulting new git repo.
 
 git-p4.largeFileSystem::
 	Specify the system that is used for large (binary) files. Please note
