Raul Silvera	e6498adf75	More careful handling of temporary directories Only create $HOME/pprof if a profile is stored remotely and must be stored. Also, create non-profile temps on os.TempDir() instead of $HOME/pprof or /tmp.	vor 8 Jahren
Alexey Alexandrov	ddacd6aa78	Reset mapping file to empty string if it was patched to be the source URL. When the source is remote and a mapping doesn't have either build ID or file field set, the file field is set to the source URL so that the proper source from the source mapping is used during symbolz processing. Before this change, the file field would continue to point to the URL producing the URL in pprof output which confuses users. With the change it resets the file field back to the empty string. It also now skips the URL-like paths during local symbolization as reading at that path is not going to succeed. We discussed switching to generating more unique IDs. On the second thought, I propose leaving these to be URLs as that seems unique enough and in case this field leaks into the tool or log output seeing the URL seems still friendlier than some arbitrarily prefixed string.	vor 8 Jahren

Wade Simba Khadder	fe37e1287e	Only do Seek if there is an EOF in the perf fetcher This is to handle the case where we have a file that is smaller than the perf.data header, but is still (or can be converted in another way) a valid profile.proto.	vor 8 Jahren

Raul Silvera	0c91ef751d	Add symbolization support for Mach-O This will enable symbolization support for Go on Mac OS It re-enables symbolization using debug/pprof/symbol on Go profiles in the legacy format, and implements basic mach-O support on the binutils package.	vor 8 Jahren
Raul Silvera	039e3813be	Chunk profile fetching pprof fetches profiles concurrently, which allows to profile multiple running servers concurrently. However, this may translate into a large use of memory if many profiles are merged, as pprof attempts to decode all profiles in parallel. Limit the concurrency by chunking the concurrent fetches in groups of up to 64 profiles.	vor 9 Jahren
