Sun, 20 Dec 2015 16:00:27 -0800 revlog: avoid string slice when decompressing u* chunks
Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 16:00:27 -0800] rev 27475
revlog: avoid string slice when decompressing u* chunks Revlog chunks can be stored uncompressed. If the first byte of the raw data is \0, we store the data as is. Else we prefix it with 'u'. Before, we performed a string slice to strip out the 'u' prefix. With this patch, we use a buffer to avoid an extra memory copy and associated garbage collection overhead. I was unable to verify any performance impact of this patch. For both mozilla-central and the hg repos, the number of manifest revisions with 'u' prefixes is very small - under 1%. So this change likely isn't called enough to have an impact on manifest reading. However, the reasoning behind this change is solid, so it should be safe.

osutil: implement recvmsg() of SCM_RIGHTS for chg command server It will be used to attach client's stdio files to a background chg command server. The socket module of Python 2.x doesn't provide recvmsg(). This could be implemented by using ctypes, but it would be less portable than the C version because the handling of socket ancillary data heavily depends on preprocessor. Also, some length fields are wrongly typed in the Linux kernel.

Sun, 20 Dec 2015 18:38:21 -0800 perf: add perfrevlogrevision
Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 18:38:21 -0800] rev 27470
perf: add perfrevlogrevision As part of investigating performance improvements to revlog reading, I needed a mechanism to measure every part of revlog reading so I knew where time was spent and how effective optimizations were. This patch implements a perf command for benchmarking the various stages of reading a single revlog revision. When executed against a manifest revision at the end of a 30,000+ long delta chain in mozilla-central, the command demonstrates that ~80% of time is spent in zlib decompression.

Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 19:02:02 -0800] rev 27469
commands: use revlog._deltachain in debugdeltachain We have a nice API now. Use it. This does mean we introduce an extra index lookup for each revision. Considering this is a debug command, the overhead should be acceptable. We could add the chain size to revlog._deltachain(). However, that feels like avoidable overhead.
Sun, 20 Dec 2015 18:56:05 -0800 revlog: refactor delta chain computation into own function
Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 18:56:05 -0800] rev 27468
revlog: refactor delta chain computation into own function This code is already written in multiple locations. While this code needs to be fast and extracting it to its own function adds overhead, code paths reading delta chains typically read, decompress, and do binary patching on revlog data from the delta chain. This other work (especially zlib decompression) almost certainly accounts for a lot more time than the overhead of introducing a Python function call. So I'm not worried about the performance impact of this change.
Sun, 20 Dec 2015 17:57:44 -0800 perf: call clearcaches() in perfmanifest
Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 17:57:44 -0800] rev 27467
perf: call clearcaches() in perfmanifest The old code only partially cleared the caches. Now that we have a comprehensive method for wiping all caches, let's call it. This appears to introduce a marginal regression in `hg perfmanifest` on mozilla-central. This is good because the new result is more accurate since caches aren't being used.

Sun, 20 Dec 2015 17:48:20 -0800 revlog: make clearcaches() more effective
Gregory Szorc <gregory.szorc@gmail.com> [Sun, 20 Dec 2015 17:48:20 -0800] rev 27465
revlog: make clearcaches() more effective clearcaches() was added several years ago in e8d37b78acfb as part of implementing a perf command. Since revlog instances have many caches and since the spirit of this mostly unused method is to facilitate performance testing, I think it's appropriate for all the revlog's caches to get cleared when it is called.
Mon, 21 Dec 2015 22:31:16 +0900 fileset: detect unintentional existing() invocation at runtime
FUJIWARA Katsunori <foozy@lares.dti.ne.jp> [Mon, 21 Dec 2015 22:31:16 +0900] rev 27464
fileset: detect unintentional existing() invocation at runtime A fileset predicate can invoke 'matchctx.existing()' successfully, even if it isn't marked as "existing caller". It is aborted only in some corner cases: e.g. there were one deleted file in the working directory (see 8a0513bf030a for detail). This patch makes 'matchctx.existing()' invocation abort if not '_existingenabled', which is true only while "existing caller" running. After this changes, non-"existing caller" predicate function is aborted immediately, whenever it invokes 'matchctx.existing()'. This prevent developer from forgetting to mark a predicate as "existing caller". BTW, unintentional 'matchctx.status()' invocation can be detected easily without any additional trick like this patch, because it returns 'None' if a predicate isn't marked as "status caller", and referring field (e.g. '.modified') of it is always aborted.

FUJIWARA Katsunori <foozy@lares.dti.ne.jp> [Mon, 21 Dec 2015 22:31:16 +0900] rev 27463
fileset: use set instead of list to mark predicates for efficiency (API) This reduces cost of examining whether given predicate calls 'matchctx.status()' or 'matchctx.existing()' in 'getfileset()' at runtime. This kind of examination is used also in subsequent patch, which detects unintentional 'matchctx.existing()' invocation per each predicate evaluation.

FUJIWARA Katsunori <foozy@lares.dti.ne.jp> [Mon, 21 Dec 2015 22:31:16 +0900] rev 27461
fileset: use decorator to mark a predicate as "status caller" Before this patch, predicates calling 'matchctx.status()' are listed up by immediate list value in 'getfileset()'. This prevents 3rd party extensions from adding specific predicate calling 'matchctx.status()'. This uses decorator to mark a predicate as "status caller". This can also localize changes for adding (or removing) a "status caller" predicate function in source code.
Mon, 21 Dec 2015 22:31:16 +0900 fileset: use decorator to mark a function as fileset predicate
FUJIWARA Katsunori <foozy@lares.dti.ne.jp> [Mon, 21 Dec 2015 22:31:16 +0900] rev 27460
fileset: use decorator to mark a function as fileset predicate Using decorator can localize changes for adding (or removing) a fileset predicate function in source code. It is also useful to pick predicates up for specific purpose. For example, subsequent patches marks predicates as "call status" or "use existing" via decorator. To avoid (1) redundancy between "predicate name" and (the beginning of) help document, and (2) accidental typo of help document, this patch also makes decorator put predicate declration into the beginning of help.
Mon, 21 Dec 2015 22:31:16 +0900 fileset: treat encoding and eol as the predicate calling _existing
FUJIWARA Katsunori <foozy@lares.dti.ne.jp> [Mon, 21 Dec 2015 22:31:16 +0900] rev 27459
fileset: treat encoding and eol as the predicate calling _existing Before this patch, predicate function 'encoding' and 'eol' aren't listed up in '_existingcallers', even though they invoke 'existing()'. This causes unexpected failure of these predicate, if there is a (manually) deleted file in the working directory. 8a0513bf030a and 3ce3f2b059a1 seem to overlook putting already existing 'encoding' or newly introduced 'eol' into '_existingcallers'. This patch also changes order of fileset "eol(unix)" output in test, because "existing caller" predicates show "A(dded)" files before "C(lean)" ones.
