Examples with LogCatHeader com.android.ddmlib.logcat.LogCatHeader used on opensource projects

Example 1 with LogCatHeader

use of com.android.ddmlib.logcat.LogCatHeader in project android by JetBrains.

the class AndroidLogcatReceiver method processNewLine.

@Override
public void processNewLine(@NotNull String line) {
    // Really, the user's log should never put any system characters in it ever - that will cause
    // it to get filtered by our strict regex patterns (see AndroidLogcatFormatter). The reason
    // this might happen in practice is due to a bug where either adb or logcat (not sure which)
    // is too aggressive about converting \n's to \r\n's, including those that are quoted. This
    // means that a user's log, if it uses \r\n itself, is converted to \r\r\n. Then, when
    // MultiLineReceiver, which expects valid input, strips out \r\n, it leaves behind an extra \r.
    //
    // Unfortunately this isn't a case where we can fix the root cause because adb and logcat are
    // both external to Android Studio. In fact, the latest adb/logcat versions have already fixed
    // this issue! But we still need to run properly with older versions. Also, putting this fix in
    // MultilineReceiver isn't right either because it is used for more than just receiving logcat.
    line = line.replaceAll("\\r", "");
    if (line.isEmpty()) {
        myDelayedNewlineCount++;
        return;
    }
    LogCatHeader header = myParser.processLogHeader(line, myDevice);
    if (header != null) {
        myStackTraceExpander.reset();
        myActiveHeader = header;
        myLineIndex = 0;
        // Intentionally drop any trailing newlines once we hit a new header. Usually, logcat
        // separates log entries with a single newline but sometimes it outputs more than one. As we
        // can't know which is user newlines vs. system newlines, just drop all of them.
        myDelayedNewlineCount = 0;
    } else if (myActiveHeader != null) {
        if (myDelayedNewlineCount > 0 && myLineIndex == 0) {
            // Note: Since we trim trailing newlines, we trim leading newlines too. Most users won't
            // use them intentionally and they don't look great, anyway.
            myDelayedNewlineCount = 0;
        } else {
            processAnyDelayedNewlines(myActiveHeader);
        }
        for (String processedLine : myStackTraceExpander.process(line)) {
            notifyLine(myActiveHeader, processedLine);
        }
    }

Example 2 with LogCatHeader

   * text doesn't match.

    final Matcher matcher = MESSAGE_WITH_HEADER.matcher(msg);
    if (!matcher.matches()) {
        return null;
    }
    // matcher.matches verifies all groups below are non-null
    @SuppressWarnings("ConstantConditions") LogCatHeader header = new LogCatHeader(Log.LogLevel.getByLetter(matcher.group(5).charAt(0)), Integer.parseInt(matcher.group(2)), Integer.parseInt(matcher.group(3)), matcher.group(4), matcher.group(6), LogCatTimestamp.fromString(matcher.group(1)));
